Global incidence, prevalence, years lived with disability (YLDs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) for 371 diseases and injuries in 204 countries and territories and 811 subnational locations, 1990-2021: a systematic analysis for the Global Burden of Disease Study 2021

BACKGROUND

Detailed, comprehensive, and timely reporting on population health by underlying causes of disability and premature death is crucial to understanding and responding to complex patterns of disease and injury burden over time and across age groups, sexes, and locations. The availability of disease burden estimates can promote evidence-based interventions that enable public health researchers, policy makers, and other professionals to implement strategies that can mitigate diseases. It can also facilitate more rigorous monitoring of progress towards national and international health targets, such as the Sustainable Development Goals. For three decades, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) has filled that need. A global network of collaborators contributed to the production of GBD 2021 by providing, reviewing, and analysing all available data. GBD estimates are updated routinely with additional data and refined analytical methods. GBD 2021 presents, for the first time, estimates of health loss due to the COVID-19 pandemic.

METHODS

The GBD 2021 disease and injury burden analysis estimated years lived with disability (YLDs), years of life lost (YLLs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) for 371 diseases and injuries using 100 983 data sources. Data were extracted from vital registration systems, verbal autopsies, censuses, household surveys, disease-specific registries, health service contact data, and other sources. YLDs were calculated by multiplying cause-age-sex-location-year-specific prevalence of sequelae by their respective disability weights, for each disease and injury. YLLs were calculated by multiplying cause-age-sex-location-year-specific deaths by the standard life expectancy at the age that death occurred. DALYs were calculated by summing YLDs and YLLs. HALE estimates were produced using YLDs per capita and age-specific mortality rates by location, age, sex, year, and cause. 95% uncertainty intervals (UIs) were generated for all final estimates as the 2·5th and 97·5th percentiles values of 500 draws. Uncertainty was propagated at each step of the estimation process. Counts and age-standardised rates were calculated globally, for seven super-regions, 21 regions, 204 countries and territories (including 21 countries with subnational locations), and 811 subnational locations, from 1990 to 2021. Here we report data for 2010 to 2021 to highlight trends in disease burden over the past decade and through the first 2 years of the COVID-19 pandemic.

FINDINGS

Global DALYs increased from 2·63 billion (95% UI 2·44-2·85) in 2010 to 2·88 billion (2·64-3·15) in 2021 for all causes combined. Much of this increase in the number of DALYs was due to population growth and ageing, as indicated by a decrease in global age-standardised all-cause DALY rates of 14·2% (95% UI 10·7-17·3) between 2010 and 2019. Notably, however, this decrease in rates reversed during the first 2 years of the COVID-19 pandemic, with increases in global age-standardised all-cause DALY rates since 2019 of 4·1% (1·8-6·3) in 2020 and 7·2% (4·7-10·0) in 2021. In 2021, COVID-19 was the leading cause of DALYs globally (212·0 million [198·0-234·5] DALYs), followed by ischaemic heart disease (188·3 million [176·7-198·3]), neonatal disorders (186·3 million [162·3-214·9]), and stroke (160·4 million [148·0-171·7]). However, notable health gains were seen among other leading communicable, maternal, neonatal, and nutritional (CMNN) diseases. Globally between 2010 and 2021, the age-standardised DALY rates for HIV/AIDS decreased by 47·8% (43·3-51·7) and for diarrhoeal diseases decreased by 47·0% (39·9-52·9). Non-communicable diseases contributed 1·73 billion (95% UI 1·54-1·94) DALYs in 2021, with a decrease in age-standardised DALY rates since 2010 of 6·4% (95% UI 3·5-9·5). Between 2010 and 2021, among the 25 leading Level 3 causes, age-standardised DALY rates increased most substantially for anxiety disorders (16·7% [14·0-19·8]), depressive disorders (16·4% [11·9-21·3]), and diabetes (14·0% [10·0-17·4]). Age-standardised DALY rates due to injuries decreased globally by 24·0% (20·7-27·2) between 2010 and 2021, although improvements were not uniform across locations, ages, and sexes. Globally, HALE at birth improved slightly, from 61·3 years (58·6-63·6) in 2010 to 62·2 years (59·4-64·7) in 2021. However, despite this overall increase, HALE decreased by 2·2% (1·6-2·9) between 2019 and 2021.

INTERPRETATION

Putting the COVID-19 pandemic in the context of a mutually exclusive and collectively exhaustive list of causes of health loss is crucial to understanding its impact and ensuring that health funding and policy address needs at both local and global levels through cost-effective and evidence-based interventions. A global epidemiological transition remains underway. Our findings suggest that prioritising non-communicable disease prevention and treatment policies, as well as strengthening health systems, continues to be crucially important. The progress on reducing the burden of CMNN diseases must not stall; although global trends are improving, the burden of CMNN diseases remains unacceptably high. Evidence-based interventions will help save the lives of young children and mothers and improve the overall health and economic conditions of societies across the world. Governments and multilateral organisations should prioritise pandemic preparedness planning alongside efforts to reduce the burden of diseases and injuries that will strain resources in the coming decades.

Global burden of 288 causes of death and life expectancy decomposition in 204 countries and territories and 811 subnational locations, 1990-2021: a systematic analysis for the Global Burden of Disease Study 2021

BACKGROUND

Regular, detailed reporting on population health by underlying cause of death is fundamental for public health decision making. Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic. When systematically analysed, mortality rates and life expectancy allow comparisons of the consequences of causes of death globally and over time, providing a nuanced understanding of the effect of these causes on global populations.

METHODS

The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 cause-of-death analysis estimated mortality and years of life lost (YLLs) from 288 causes of death by age-sex-location-year in 204 countries and territories and 811 subnational locations for each year from 1990 until 2021. The analysis used 56 604 data sources, including data from vital registration and verbal autopsy as well as surveys, censuses, surveillance systems, and cancer registries, among others. As with previous GBD rounds, cause-specific death rates for most causes were estimated using the Cause of Death Ensemble model-a modelling tool developed for GBD to assess the out-of-sample predictive validity of different statistical models and covariate permutations and combine those results to produce cause-specific mortality estimates-with alternative strategies adapted to model causes with insufficient data, substantial changes in reporting over the study period, or unusual epidemiology. YLLs were computed as the product of the number of deaths for each cause-age-sex-location-year and the standard life expectancy at each age. As part of the modelling process, uncertainty intervals (UIs) were generated using the 2·5th and 97·5th percentiles from a 1000-draw distribution for each metric. We decomposed life expectancy by cause of death, location, and year to show cause-specific effects on life expectancy from 1990 to 2021. We also used the coefficient of variation and the fraction of population affected by 90% of deaths to highlight concentrations of mortality. Findings are reported in counts and age-standardised rates. Methodological improvements for cause-of-death estimates in GBD 2021 include the expansion of under-5-years age group to include four new age groups, enhanced methods to account for stochastic variation of sparse data, and the inclusion of COVID-19 and other pandemic-related mortality-which includes excess mortality associated with the pandemic, excluding COVID-19, lower respiratory infections, measles, malaria, and pertussis. For this analysis, 199 new country-years of vital registration cause-of-death data, 5 country-years of surveillance data, 21 country-years of verbal autopsy data, and 94 country-years of other data types were added to those used in previous GBD rounds.

FINDINGS

The leading causes of age-standardised deaths globally were the same in 2019 as they were in 1990; in descending order, these were, ischaemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. In 2021, however, COVID-19 replaced stroke as the second-leading age-standardised cause of death, with 94·0 deaths (95% UI 89·2-100·0) per 100 000 population. The COVID-19 pandemic shifted the rankings of the leading five causes, lowering stroke to the third-leading and chronic obstructive pulmonary disease to the fourth-leading position. In 2021, the highest age-standardised death rates from COVID-19 occurred in sub-Saharan Africa (271·0 deaths [250·1-290·7] per 100 000 population) and Latin America and the Caribbean (195·4 deaths [182·1-211·4] per 100 000 population). The lowest age-standardised death rates from COVID-19 were in the high-income super-region (48·1 deaths [47·4-48·8] per 100 000 population) and southeast Asia, east Asia, and Oceania (23·2 deaths [16·3-37·2] per 100 000 population). Globally, life expectancy steadily improved between 1990 and 2019 for 18 of the 22 investigated causes. Decomposition of global and regional life expectancy showed the positive effect that reductions in deaths from enteric infections, lower respiratory infections, stroke, and neonatal deaths, among others have contributed to improved survival over the study period. However, a net reduction of 1·6 years occurred in global life expectancy between 2019 and 2021, primarily due to increased death rates from COVID-19 and other pandemic-related mortality. Life expectancy was highly variable between super-regions over the study period, with southeast Asia, east Asia, and Oceania gaining 8·3 years (6·7-9·9) overall, while having the smallest reduction in life expectancy due to COVID-19 (0·4 years). The largest reduction in life expectancy due to COVID-19 occurred in Latin America and the Caribbean (3·6 years). Additionally, 53 of the 288 causes of death were highly concentrated in locations with less than 50% of the global population as of 2021, and these causes of death became progressively more concentrated since 1990, when only 44 causes showed this pattern. The concentration phenomenon is discussed heuristically with respect to enteric and lower respiratory infections, malaria, HIV/AIDS, neonatal disorders, tuberculosis, and measles.

INTERPRETATION

Long-standing gains in life expectancy and reductions in many of the leading causes of death have been disrupted by the COVID-19 pandemic, the adverse effects of which were spread unevenly among populations. Despite the pandemic, there has been continued progress in combatting several notable causes of death, leading to improved global life expectancy over the study period. Each of the seven GBD super-regions showed an overall improvement from 1990 and 2021, obscuring the negative effect in the years of the pandemic. Additionally, our findings regarding regional variation in causes of death driving increases in life expectancy hold clear policy utility. Analyses of shifting mortality trends reveal that several causes, once widespread globally, are now increasingly concentrated geographically. These changes in mortality concentration, alongside further investigation of changing risks, interventions, and relevant policy, present an important opportunity to deepen our understanding of mortality-reduction strategies. Examining patterns in mortality concentration might reveal areas where successful public health interventions have been implemented. Translating these successes to locations where certain causes of death remain entrenched can inform policies that work to improve life expectancy for people everywhere.

Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950-2021, and the impact of the COVID-19 pandemic: a comprehensive demographic analysis for the Global Burden of Disease Study 2021

BACKGROUND

Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 countries and territories and 811 additional subnational locations from 1950 to 2021, with a particular emphasis on changes in mortality and life expectancy that occurred during the 2020-21 COVID-19 pandemic period.

METHODS

22 223 data sources from vital registration, sample registration, surveys, censuses, and other sources were used to estimate mortality, with a subset of these sources used exclusively to estimate excess mortality due to the COVID-19 pandemic. 2026 data sources were used for population estimation. Additional sources were used to estimate migration; the effects of the HIV epidemic; and demographic discontinuities due to conflicts, famines, natural disasters, and pandemics, which are used as inputs for estimating mortality and population. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate under-5 mortality rates, which synthesised 30 763 location-years of vital registration and sample registration data, 1365 surveys and censuses, and 80 other sources. ST-GPR was also used to estimate adult mortality (between ages 15 and 59 years) based on information from 31 642 location-years of vital registration and sample registration data, 355 surveys and censuses, and 24 other sources. Estimates of child and adult mortality rates were then used to generate life tables with a relational model life table system. For countries with large HIV epidemics, life tables were adjusted using independent estimates of HIV-specific mortality generated via an epidemiological analysis of HIV prevalence surveys, antenatal clinic serosurveillance, and other data sources. Excess mortality due to the COVID-19 pandemic in 2020 and 2021 was determined by subtracting observed all-cause mortality (adjusted for late registration and mortality anomalies) from the mortality expected in the absence of the pandemic. Expected mortality was calculated based on historical trends using an ensemble of models. In location-years where all-cause mortality data were unavailable, we estimated excess mortality rates using a regression model with covariates pertaining to the pandemic. Population size was computed using a Bayesian hierarchical cohort component model. Life expectancy was calculated using age-specific mortality rates and standard demographic methods. Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution.

FINDINGS

Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62·8% [95% UI 60·5-65·1] decline), and increased during the COVID-19 pandemic period (2020-21; 5·1% [0·9-9·6] increase). In contrast with the overall reverse in mortality trends during the pandemic period, child mortality continued to decline, with 4·66 million (3·98-5·50) global deaths in children younger than 5 years in 2021 compared with 5·21 million (4·50-6·01) in 2019. An estimated 131 million (126-137) people died globally from all causes in 2020 and 2021 combined, of which 15·9 million (14·7-17·2) were due to the COVID-19 pandemic (measured by excess mortality, which includes deaths directly due to SARS-CoV-2 infection and those indirectly due to other social, economic, or behavioural changes associated with the pandemic). Excess mortality rates exceeded 150 deaths per 100 000 population during at least one year of the pandemic in 80 countries and territories, whereas 20 nations had a negative excess mortality rate in 2020 or 2021, indicating that all-cause mortality in these countries was lower during the pandemic than expected based on historical trends. Between 1950 and 2021, global life expectancy at birth increased by 22·7 years (20·8-24·8), from 49·0 years (46·7-51·3) to 71·7 years (70·9-72·5). Global life expectancy at birth declined by 1·6 years (1·0-2·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15·7%) of 204 countries and territories between 2019 and 2021. The global population reached 7·89 billion (7·67-8·13) people in 2021, by which time 56 of 204 countries and territories had peaked and subsequently populations have declined. The largest proportion of population growth between 2020 and 2021 was in sub-Saharan Africa (39·5% [28·4-52·7]) and south Asia (26·3% [9·0-44·7]). From 2000 to 2021, the ratio of the population aged 65 years and older to the population aged younger than 15 years increased in 188 (92·2%) of 204 nations.

INTERPRETATION

Global adult mortality rates markedly increased during the COVID-19 pandemic in 2020 and 2021, reversing past decreasing trends, while child mortality rates continued to decline, albeit more slowly than in earlier years. Although COVID-19 had a substantial impact on many demographic indicators during the first 2 years of the pandemic, overall global health progress over the 72 years evaluated has been profound, with considerable improvements in mortality and life expectancy. Additionally, we observed a deceleration of global population growth since 2017, despite steady or increasing growth in lower-income countries, combined with a continued global shift of population age structures towards older ages. These demographic changes will likely present future challenges to health systems, economies, and societies. The comprehensive demographic estimates reported here will enable researchers, policy makers, health practitioners, and other key stakeholders to better understand and address the profound changes that have occurred in the global health landscape following the first 2 years of the COVID-19 pandemic, and longer-term trends beyond the pandemic.

Epidemiology of maxillofacial injury among adults in sub-Saharan Africa: a scoping review

BACKGROUND

Injuries remain one of the leading causes of death globally. These disproportionately affect young adults and are particularly prevalent in sub-Saharan Africa (SSA). Maxillofacial injuries (MI) pose significant challenges to public health systems. However, much remains unknown regarding the epidemiology and extent of the financial burden in resource-limited areas, such as SSA, further necessitating more research and support. This scoping review aims to investigate the mechanism, distribution, and financial impact of MI in adults aged ≥ 18 years in SSA.

MAIN BODY

The scoping review was guided by the methodological frameworks of Arksey and O'Malley and Levac. An electronic literature search for English-published articles on maxillofacial injuries in adults ≥ 18 years was conducted in Scopus, Medline, PubMed, Science Direct, CINAHL, Health Source: Nursing/Academic Edition, and grey literature. The PRISMA chart was used to document database searches and screening outcomes while reporting was guided by PRISMA-ScR. The data extraction process revolved around the predefined study outcomes, which encompassed the study characteristics and epidemiological parameters. The review used a narrative approach to report findings and evaluate publication quality using the STROBE checklist. The database search yielded 8246 studies, of which 30 met the inclusion criteria. A total of 7317 participants were included, 79.3% of whom were males. The peak age range for incidence was between 18 and 40 years. Road traffic collision (RTC) was the leading cause of MI, 59% of which resulted from motorcycle collisions. Assault/interpersonal violence ranked as the second leading cause of MI. The mandible was MI's most frequently affected hard tissue, followed by the midface. Factors such as alcohol/illicit drug use, poor knowledge of traffic regulations, and non-observance of these regulations were associated with MI. In our study, the cost range for mandibular fractures was $200-$468.6, borne by victims and their families.

CONCLUSIONS

Maxillofacial injuries are predominantly caused by road traffic collisions and assaults in SSA. The findings can provide valuable insights into policy decisions and prevention strategies aimed at reducing injury burden. Further research is warranted to explore the psychological impact of MI, including PTSD, for tailored support and intervention.

Cervical Cancer Screening and Treatment algorithms using Human Papillomavirus testing - lessons learnt from a South African pilot randomized controlled trial

BACKGROUND

To report quantitative and qualitative results on cervical cancer (CC) HPV-based screening and treatment algorithms, with/out triage with visual inspection after acetic acid (VIA), followed by ablative treatment (AT).

METHODS

Women 30-54 years-old from Durban, South Africa were recruited, regardless of HIV status, randomized into one of two study arms and screened for HPV. VIA-triage arm: HPV-positive women were triaged using VIA, biopsied and received AT if VIA-positive and eligible; no-triage arm: eligible HPV-positive women received AT. Women ineligible for AT were referred to colposcopy. Women were asked about side effects immediately and one week after AT. Retention to screening and treatment algorithms was compared between arms.

RESULTS

350 women (275 HIV-uninfected and 75 women living with HIV, (WLWH)) were allocated to receive HPV testing with VIA-triage (n=175) or no-triage (n=175). HPV prevalence was 28% (95%CI=23-33); WLWH: 52% (95%CI=40-64) vs HIV-uninfected: 21% (95%CI=17-27) (p<0.05). Among women who underwent VIA triage with histological diagnosis, 3/17 were VIA negative with CIN2+; 14/18 were VIA positive with

CONCLUSION

This pilot demonstrated the feasibility of implementing screening and treatment algorithms, including performing triage and treatment in one visit; however VIA triage did not reduce overtreatment and missed some precancerous lesions.

IMPACT

This study reports on implementation feasibility of two WHO screening and treatment algorithms (with/out VIA-triage). Although the retention to screening and treatment algorithms was high in both arms, the question of how best triaging HPV-positive women deserves further consideration, particularly for WLWH.

Understanding adolescent girls' experiences with accessing and using contraceptives in Zambia

BACKGROUND

Globally, the unmet need for contraception among adolescent girls is high and is driven by barriers to access and utilisation of contraceptives. Understanding adolescent girls' experiences with accessing and using contraceptives is crucial because it influences their decision to use and willingness to continue using health products and services. While determinants of contraceptive use have been extensively researched globally, few studies explore how adolescent girls experience contraceptive use in Zambia using qualitative methods. Therefore, this study aimed to understand Zambian adolescent girls' experiences using contraceptives.

METHODS

Thematic analysis was used to analyse data generated from 7 focus group discussions and three in-depth interviews with adolescent girls aged 15 to 19 years in 4 districts in Zambia. NVivo version 12 pro (QSR International) software was used to manage and organise the data.

RESULTS

Results revealed that adolescents' experiences concerning contraceptives across the continuum of care are shaped by various factors, including knowledge of contraceptives which comprises sources of information and contraceptives; experience with using contraceptives, challenges with access to contraceptives, and misconceptions about contraceptives; perspectives about existing contraceptives; and preferred types of contraceptives.

CONCLUSION

The multifactorial interaction relating to adolescents' personal experience, their community and the environment in which they access contraceptive services all contribute to their overall experience and influence their contraceptive decisions. Therefore, qualitative studies exploring adolescents' experiences with accessing and using contraceptives are vital for tailoring interventions responsive to the contraceptive needs of this age group.

Availability, stock levels and usage of In-vitro diagnostics in the Bono region, Ghana: A cross-sectional study

BACKGROUND

Point-of-care (POC) diagnostic tests play essential roles in diagnosis, surveillance, and disease management in health settings. Nevertheless, implementation challenges may hamper POC test accessibility. This study evaluated the availability and stock levels of the World Health Organization (WHO) prequalified existing in-vitro diagnostics (IVDs) for use in health facilities without laboratories.

AIM

To evaluate the availability, stock levels, and usage of POC diagnostic tests.

SETTING

Bono Region, Ghana.

METHODS

This cross-sectional survey involved 102 randomly selected Community Health-based and Planning Services (CHPS), 12 district health depots, and a regional medical depot. Using a survey tool, data were collected on clinic staffing, availability and stock levels of tests, and funding sources. STATA 17 was employed for data analysis.

RESULTS

Majority (37.3%) of the respondents were community health nurses, with 4.4 mean years of work experience and 38 working hours per week. Of the 18 existing WHO prequalified POC tests for use at facilities without laboratories, 10 (56%), 2 (11%) and 0 (0%) were found at CHPS, regional, and district depots, respectively. Majority (183 out of 301) stock levels were low. Of the 10 available tests found, 7 scored 111 (36%) of 'high use'. Supply chain management compliance was 5 (31%) out of 16. All CHPS received government funding with 25.5% of them receiving additional donor or internally generated funding.

CONCLUSION

This study found poor supply chain management compliance, and low availability of POC tests in the Bono Region of Ghana.Contribution: The study outlines POC tests availability and usage in low-resourced setting.

Factors contributing to changes in contraceptive use among adolescent girls in Zambia: a decomposition analysis

Despite its documented benefits, contraceptive use among adolescents remains low, particularly in low-and middle-income countries. This study aimed to decompose the main factors contributing to the changes in contraceptive use among adolescent girls in Zambia over the period 1996 to 2014. Data on adolescent girls aged 15-19 years from Zambia Demographic and Health Survey data were analysed using multivariate decomposition analysis of change. Stata 15/MP (Stata-Corp LLC) was used for analysis, at a 95% confidence level. A P-value of 0.05 was used to determine statistical significance. The sample included 9,072 adolescent girls. Contraceptive use increased by 3% from 7.6% in 1996 to 10.6% in 2013/14. Change in modern contraceptive use among adolescents was mainly due to differences in coefficients (changes in population behaviour). Increases in age contributed to the change in contraceptive use, resulting in 2.94 and 9.33% increases for 17- and 18-year-olds respectively. Marriage or living with a partner contributed the largest change (44%) while living in a rural area accounted for approximately 20%. Interventions targeting improving contraceptive use in adolescents should be responsive to the needs of various age groups, places of residence, and educational levels for maximum benefits.

Quality measures for palliative care in patients living with cancer in low- and middle-income countries: a scoping review protocol

INTRODUCTION

Quality assessment is a critical component of determining the value of medical services, including palliative care. The utilisation of palliative care quality measures could assist in assessing the degree to which patients living with cancer conform to best practice of palliative care, identifying gaps and monitoring changes in cancer care delivery models in different setting. This scoping review aims to map the available data on the usage of palliative care quality indicators that are relevant to cancer patients in low- and middle-income countries (LMICs).

METHODS

To structure this study, we will use the framework developed by Arksey and O'Malley, the Levac et al. recommendations and the Joanna Briggs Institute recommendations. We will search EBSCOHost, Web of Science, ProQuest One Academic, MEDLINE and Google Scholar for evidence on palliative care quality measures applicable for patients living with cancer published from inception till 2022. We will search grey literature in the form of dissertations, conference proceedings and websites of international organisations such as the World Health Organisation (WHO) reporting palliative care quality measures applicable to patients living with cancer in LMICs.

DISCUSSION

The purpose of this study is to establish the extent of existing research on the palliative care quality measures in LMICs. Although palliative care is still a new phenomenon, understanding of the palliative care quality measures applicable for cancer patients will assist to improve care across all components of health systems.

ETHICS AND DISSEMINATION

No ethical approval is required for the study as the data collection and results of the proposed scoping review will be conducted and disseminated electronically using peer-reviewed journals, print and presentations at scientific conferences and stakeholder presentations.

"Why Am I Even Here If I Can't Save the Patients?": The Frontline Healthcare Workers' Experience of Burnout during COVID-19 Pandemic in Mthatha, South Africa

INTRODUCTION

Globally, the high prevalence of burnout in healthcare workers (HCWs) is of the utmost concern. Burnout is a state of emotional exhaustion, depersonalization and a decreased sense of personal accomplishment. While the 2019 Coronavirus (COVID-19) exacerbated the burnout prevalence among HCWs, limited studies have explored this phenomenon using qualitative methodologies in the Eastern Cape Province and South Africa generally. This study explored how frontline healthcare workers experienced burnout during the COVID-19 pandemic in Mthatha Regional Hospital.

METHODS

Ten face-to-face in-depth interviews were conducted with non-specialized medical doctors and nurses who directly cared for COVID-19-infected patients during the pandemic in Mthatha Regional Hospital (MRH). In-depth interviews were digitally recorded and transcribed verbatim. Data were managed through NVIVO 12 software before being thematically analyzed using Colaizzi's analysis method.

RESULTS

Four main themes emerged from the analysis. These themes were burnout manifestation (emotional strain, detachment and irritability, uncertainty-induced fear, and anxiety, physical exhaustion, yet, low job accomplishment, dread and professional responsibility), precursors of burnout (occupational exposure to high mortality, staff shortages, elongated high patient volume and workload, disease uncertainties and consistent feeling of grief), alleviating factors of burnout (time off work, psychologist intervention, periods of low infection rate and additional staff), and the last theme was every cloud has a silver lining (improved infection prevention and control (IPC) measures, learning to be more empathetic, the passion remains and confidence grows).

CONCLUSION

The COVID-19 pandemic brought about a rapid change in the work environment of healthcare workers who are the backbone of efficient healthcare services, thereby rendering them vulnerable to increased burnout risks. This study provides strategic information for policymakers and managers on developing and strengthening welfare policies to promote and protect frontline health workers' well-being and work functioning.

The Prevalence of Compassion Fatigue among Oncology Healthcare Professionals in Three Public Healthcare Facilities in Kwazulu-Natal, South Africa

Compassion fatigue (CF) is a serious global challenge among healthcare professionals dealing with diseases with poor health outcomes in clinical settings. Chronic exposure to the suffering of others is inevitable in the oncology setting and remains one of the main contributors to CF. Therefore, this study determined the prevalence of CF among oncology healthcare professionals (OHPs) in three public healthcare facilities in KwaZulu-Natal, South Africa. This cross-sectional descriptive study was conducted among 73 OHPs using the Professional Quality of Life Scale version 5 questionnaire, and the data were analysed using the Statistical Package for Social Sciences. More than half (56.2%) of the participants reported average scores for CF, with 43.8% of them scoring low. The participants from Inkosi Albert Luthuli Central Hospital had the highest CF mean score (26.8) compared to those from Addington Hospital (21.2) and Greys Hospital (22.9). Female OHPs had a higher mean score (24.3) for CF, compared to their male counterparts (20.6). The CF scores were positively correlated with older age and longer work experience of the OHPs. The prevalence of CF among OHPs was average, compared to those reported by other local and international studies. Nevertheless, these results cannot be taken lightly, given the straining effects of unmanaged CF on the healthcare system generally and on patient care in particular. The results of this study can potentially contribute to policy development and the planning of intervention strategies towards the effective management of CF among OHPs.

Motivators and Influencers of Adolescent Girls' Decision Making Regarding Contraceptive Use in Four Districts of Zambia

Low contraceptive use in sub-Saharan Africa, and Zambia specifically, negates the potential benefits of contraception in preventing unwanted and early pregnancies. This study aimed to explore and understand the motivators and influencers of adolescent girls' contraceptive decision making. Using thematic analysis, we analysed qualitative data from seven focus group discussions and three key informant interviews with adolescent girls aged 15 to 19 years in four Zambian districts. The data were managed and organised using NVivo version 12 pro (QSR International). Fear of pregnancy, fear of diseases, fear of having more children, and spacing of children (especially among married adolescents) were key motivators for adolescents' contraceptive use. Friends and peers motivated them to use contraceptives while fear of side effects and fear of infertility drove non-use. Peer pressure and fear of mocking by their friends were important deterrents to contraceptive use. Parents, peers and friends, family members, partners, churches, and religious groups influenced adolescent girls' contraceptive decisions. Mixed messages from these influencers, with some in favour and others against contraceptives, make adolescents' decisions to use contraceptives complex. Therefore, interventions targeting increased contraceptive use should be all-inclusive, incorporating multiple influencers, including at institutional and policy levels, to empower adolescents and give them autonomy to make contraceptive decisions.

Mapping Evidence Regarding Decision-Making on Contraceptive Use among Adolescents in Sub-Saharan Africa: A Scoping Review

This scoping review mapped and synthesised existing evidence on the influence of individual, parental, peer, and societal-related factors on adolescents' decisions to use contraception in sub-Saharan Africa (SSA). Peer-reviewed and review articles published before May 2022, targeting adolescents aged 10-19 years were searched in PubMed, MEDLINE with Full Text via EBSCOhost, PsychINFO via EBSCOhost, CINAHL with Full Text via EBSCOhost, Google Scholar, Science Direct, and Scopus databases. Seven studies were included and analysed using thematic analysis based on the social-ecological model (SEM) and reported using the preferred reporting items for systematic reviews and meta-analyses (PRISMA). Individual (fear of side effects, fear of infertility), parental (parental disappointment and disapproval), peer (social stigma), partner (association with promiscuity and multiple sexual partners), societal and community (contraceptive use disapproval and stigma), and institutional and environmental factors (lack of privacy and confidentiality) influence contraceptive decisions among adolescents. These also include a lack of accurate information, social exclusion, negative health provider attitudes, and a lack of infrastructure that provides privacy and safe spaces. Identifying and addressing core issues within the context of local cultural practices that restrict contraceptive use is important. Holistic, inclusive approaches that promote the well-being of adolescents must be utilised to provide a conducive environment that ensures privacy, confidentiality, safety, and easy access to contraceptive services.

Facilitators and barriers to in vitro diagnostics implementation in resource-limited settings: A scoping review

BACKGROUND

The World Health Organization (WHO) developed the model list of essential in vitro diagnostics (EDL) to guide countries to develop and update point-of-care (POC) per their disease priorities. The EDL includes POC diagnostic tests for use in health facilities without laboratories; however, their implementation might face several challenges in low- and middle-income countries (LMICs).

AIM

To identify facilitators and barriers to POC testing service implementations in the primary health care facilities in the LMICs.

SETTING

Low- and middle-income countries.

METHODS

This scoping review was guided by Arksey and O'Malley's methodological framework. A comprehensive keyword search for literature was conducted in Google Scholar, EBSCOhost, PubMed, Web of Science and ScienceDirect using the Boolean terms ('AND' and 'OR'), as well as Medical Subject Headings. The study considered published articles in the English language from 2016 to 2021 and was limited to qualitative, quantitative and mixed-method studies. Two reviewers independently screened the articles at the abstract and full-text screening phases guided by the eligibility criteria. Data were analysed qualitatively and quantitatively.

RESULTS

Of the 57 studies identified through literature searches, 16 met this study's eligibility criteria. Of the 16 studies, 7 reported on both facilitators and barriers; and the remainder reported on only barriers to POC test implementation such as inadequate funding, insufficient human resource, stigmatisation, et cetera.

CONCLUSION

The study demonstrated a wide research gap in facilitators and barriers, especially in the general POC diagnostic test for use in health facilities without laboratories in the LMICs. Extensive research in POC testing service is recommended to improve service delivery.Contribution: This study's findings contribute to a few works of literature on existing evidence of POC testing.

Pre- and post-intervention survey on lung cancer awareness among adults in selected communities in KwaZulu-Natal, South Africa: A quasi-experimental study

Background

Lung cancer remains the number one cause of cancer mortality estimated at 1.8 million deaths. There are limited studies in resource poor countries regarding knowledge, attitudes and practices towards lung cancer.

Objective

This study aimed to assess the effects of a lung cancer awareness intervention in selected communities in KwaZulu- Natal, South Africa.

Materials and Methods

A quasi-experimental study design was conducted in the selected communities in KwaZulu-Natal. A community intervention was administered in the communities after a baseline survey. The intervention effects were assessed a month after implementation.

Results

There were statistical differences in the mean age (p<0.001) and proportion of males and females (p<0.001) at baseline and post-intervention. There were no differences in terms of smoking status (p=0.958), however, there was a reduction in the number of cigarettes smoked per day (p<0.001) and the number of packs smoked per week (p=0.026). The mean knowledge score increased from 41.8% (95% CI 35.7 - 47.9) at baseline to 59.9 (95% CI 53.8 - 66.0) post-intervention (p<0.001). The proportion of participants who were aware that lung cancer can be detected early increased from 46.5% (95% CI 39.1 - 53.9) at baseline to 81.1% (95% CI 71.7 - 87.9) post-intervention (p<0.001). The intervention had a statistically significant effect (aOR 4.370, 95% CI 1.477-12.928) on the level of lung cancer knowledge in the selected communities (p<0.001).

Conclusions

Interventions increasing the recognition of signs and symptoms, focusing on the importance of early detection and health seeking behaviour (including screening), smoking cessation, and addressing the perceived health system barriers are required.

Mapping Evidence on the Epidemiology and Cost Associated with Maxillofacial Injury among Adults in Sub-Saharan Africa: A Scoping Review Protocol

(1) Background: Maxillofacial injury (MI) occurs universally, for it disregards preference for age, gender, and geographical region. The global incidence and prevalence of facial fractures rose by 39.45% and 54.39%, respectively, between the years 1990 to 2017. Projections indicate that the burden of injuries will persist in sub-Saharan Africa (SSA) in the next twenty years. This scoping review aims to map the literature on MI epidemiology and the economic burden on society in SSA. (2) Methods: The methodology presented by Arksey and O'Malley and extended by Levac and colleagues will be employed in the scoping review. The researcher will report the proposed review through the Preferred Reporting Items for Systematic Review, and Meta-Analysis extension for scoping reviews (PRISMA-ScR). The review will include studies encompassing MI in sub-Saharan African adults 18 years and above. (3) Results: This will be presented as a thematic analysis of the data extracted from the included studies, and the Nvivo version 12 will be employed. (4) Discussion: We anticipate searching for related literature on the prevalence, incidence, risk factors, mortality, and cost associated with MI in the adult population of SSA. The conclusion from the review will assist in ascertaining research gaps, informing policy, planning, authorizing upcoming research, and prioritizing funding for injury prevention and management.

Lung cancer awareness training experiences of community health workers in KwaZulu-Natal, South Africa

BACKGROUND

Lung cancer is the leading cause of cancer mortality worldwide. Awareness interventions in the developing world remain scarce. Community health workers (CHWs) are a critical component towards ensuring efficient delivery of healthcare services in low- and middle-income countries.

AIM

This study explored the experiences of CHWs of their training as lung cancer awareness intervention implementers.

SETTING

The study was conducted in a resource-poor setting, with CHWs from previously disadvantaged communities.

METHODS

On the last day of training, 10 CHWs were requested to voluntarily participate in a focus group discussion regarding their experiences of the training, utilising a discussion guide.

RESULTS

The participants expressed positive experiences with the training. They cited the amenable and conducive learning environment established by the facilitator. The participants felt empowered through the newly acquired knowledge and wanted to help their communities. However, some participants expressed a desire to have other forms of learning incorporated in future training. The participants were also cognisant of existing gaps in their own knowledge that could be elaborated upon in preparation for potential questions by the community. Some participants confirmed their role as agents of change.

CONCLUSION

The authors propose large-scale intervention studies of lung cancer awareness utilising the CHW programme to gather conclusive evidence regarding their effectiveness at a community level.Contribution: This article provides insight into the training of community health workers on lung cancer awareness and future research on the integration of the intervention into already existing programmes.

The preference of women living with HIV for the HPV self-sampling of urine at a rural HIV clinic in Uganda

Background

Women living with HIV have a double risk of acquiring cervical cancer (CC) due to repeated human papilloma virus (HPV) infections resulting from reduced immunity, with CC screening being low at 46.7%.

Objectives

To determine the factors associated with the preference for HPV self-sampling using urine as well as establish its feasibility among women living with HIV attending a rural HIV clinic in Uganda.

Method

A cross-sectional study design using quantitative data collection methods was used at the HIV clinic, Luweero District Hospital, among 426 women aged between 30 and 65 years. Data were analysed using descriptive statistics and modified Poisson regression. Urine samples were analysed using a Liferiver high-risk HPV genotyping real-time polymerase chain reaction (PCR) kit to determine the prevalence of the 15 HPV subtypes. Cervical intraepithelial neoplasia 2 (CIN2) was determined by visual inspection under acetic acid (VIA) using the nurse-led approach.

Results

Most women (296/426, 70%) preferred nurse-led screening. Preference for HPV self-sampling using urine was associated with older age (46-65 years) (adjusted prevalence risk ratios [aPRR] 1.59; 95% confidence interval [CI]: 1.13-2.24), history of sexually transmitted infections (aPRR 0.74: 95% CI: 0.55-0.98) and acquisition of CC information from the television (aPRR 1.48: 95% CI: 1.09-2.02). Approximately 97% (68/70) of women living with HIV tested HPV positive with one or more subtypes. The most prevalent subtype of HPV was HPV 58 (87.1%). Only one woman tested positive with VIA.

Conclusion

Nurse-led CC screening is preferred among women living with HIV, and HPV self-sampling using urine is feasible at the HIV clinic. Therefore, educational programmes to reassure the masses about urine HPV self-sampling need to be designed.

Contribution

This study's findings provide early insights into the merits and demerits of the current HPV sample collection approaches. Hence, HPV testing should be tailored to routine HIV care in rural communities.

Lung Cancer Patients' Conceptualization of Care Coordination in Selected Public Health Facilities of KwaZulu-Natal, South Africa

BACKGROUND

Cancer patients commonly receive care, including comprehensive treatment options, from multiple specialists within and across facilities offering varying levels of care. Given this multi-layered approach to cancer care, there is a need for coordinated care enhanced through integrated information flow for optimal patient care and improved health outcomes.

OBJECTIVE

This study aimed to explore how patients conceptualized cancer care coordination in an integrated health care system in KwaZulu-Natal.

METHODS

The study employed a grounded theory design to qualitatively explore the patients' experiences and views on cancer care coordination using in-depth interviews. Guided by the grounded theory principles, data generation and analysis were conducted iteratively, followed by systematic thematic analysis to organize data, and review and interpret comprehensive findings. This process culminated in the development of themes relating to barriers to cancer care coordination and the interface between the primary and tertiary settings. Theoretical saturation was achieved at 21 in-depth interviews with consenting respondents.

RESULTS

This study revealed that care coordination was affected by multilevel challenges, including pertinent health system-level factors, such as difficulty accessing specialty care timeously, weak communication between patients and healthcare providers, and unmet needs concerning supportive care. We found that negative experiences with cancer care erode patient trust and receptiveness to cancer care, and patients advocated for better and proactive coordination amongst different care facilities, services, and providers.

CONCLUSIONS

An integrated care coordination setup is essential to create and sustain a high-performance health care system. These findings make a case for developing, implementing, and evaluating interventions to enhance the quality of cancer care for patients and ultimately improve health outcomes for patients in KwaZulu-Natal. This study will provide comprehensive data to inform professionals, policymakers, and related decisionmakers to manage and improve cancer care coordination.

Cervical cancer management in Zimbabwe (2019–2020)

Background

Globally, cervical cancer is the fourth most commonly diagnosed cancer amongst women, and it is especially common in low- and middle-income countries (LMICs). The aim of the study was to determine the current patterns and characteristics of CC management in Zimbabwe in the HIV pandemic era, including the knowledge, attitude and practice of patience.

Methods

The study was a mixed method which incorporated a cross-sectional survey of 408 CC patients which was conducted from October 2019 to September 2020 using an interviewer administered paper questionnaire. The study was conducted at Parirenyatwa hospital, the only cancer treating public health facility in Harare, Zimbabwe. Differences in study outcome by categorical variables were assessed using the Person Chi-square (χ²) test. Odds ratios (unadjusted and adjusted) and 95%CIs for potential risk factors associated with the outcome were estimated using logistic regression model.

Results

From a total of 408 CC patients recruited into the study no prevention mechanism was available or known to these patients and only 13% knew that CC is caused by Human papillomavirus. Only 87 (21%) had ever been screened for CC and 83 (97%) of those who had been screened had the visual inspection with acetic acid procedure done. Prevention (screening uptake) is statistically high among the educated (with secondary education OR = 9.497, 95%CI: 2.349–38.390; with tertiary OR = 59.381, 95%CI: 11.937–295.380). Late presentation varied statistically significantly with marital status (high among the divorced, OR = 2.866; 95% CI: 1.549–5.305 and widowed OR = 1.997; 95% CI: 1.112–3.587), was low among the educated (Tertiary OR = .393; 95% CI: .166-.934), low among those living in the rural (OR = .613; 95% CI: .375-.987), high among those with higher parity OR = 1.294; 95% CI: 1.163–1.439). Less than 1% of the patients had surgery done as a means of treatment. Radiotherapy was administered to 350 (86%) of the patients compared to chemotherapy administered to 155 (38%). A total of 350 (86%) have failed to take medication due to its unavailability, while 344 (85%) missed taking medication due to unaffordability. Complementary and alternative medicines were utilized by 235 (58%). Majority, 278 (68%) were HIV positive, mainly pronounced within age (36–49 years OR = 12.673; 95% CI: 2.110–76.137), among those with higher education (secondary education OR = 4.981; 95%CI: 1.394–17.802 and in those with no co-morbidities (893.956; 95%CI: 129.611–6165.810).

Conclusion

CC management was inadequate from prevention, screening, diagnosis, treatment and palliative care hence there is need to improve CC management in Zimbabwe if morbidity and mortality are to be reduced to acceptable levels. Education helped improve prevention, but reduces chances of diagnosis, working as a doubled edged sword in CC management Prevention was high among the educated. Those in rural areas experience poor CC management. It should be noted that general education is good; however it must be complimented by CC awareness to improve CC management outcomes holistically. Cervical cancer management services need to be decentralized so that those in rural areas have easy access. Given that those with co-morbidities and high parity have better CC management, CC services need to be tied to co-morbidity and antenatal/post-natal care and management services.

The global burden of cancer attributable to risk factors, 2010-19: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally.

METHODS

The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented.

FINDINGS

Globally, in 2019, the risk factors included in this analysis accounted for 4·45 million (95% uncertainty interval 4·01-4·94) deaths and 105 million (95·0-116) DALYs for both sexes combined, representing 44·4% (41·3-48·4) of all cancer deaths and 42·0% (39·1-45·6) of all DALYs. There were 2·88 million (2·60-3·18) risk-attributable cancer deaths in males (50·6% [47·8-54·1] of all male cancer deaths) and 1·58 million (1·36-1·84) risk-attributable cancer deaths in females (36·3% [32·5-41·3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20·4% (12·6-28·4) and DALYs by 16·8% (8·8-25·0), with the greatest percentage increase in metabolic risks (34·7% [27·9-42·8] and 33·3% [25·8-42·0]).

INTERPRETATION

The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Cervical cancer screening by visual inspection and HPV testing in Eswatini

In 2009, visual inspection with acetic acid (VIA) followed by cryotherapy (VIA-and-cryotherapy), was introduced into the Eswatini cervical cancer prevention programme. We present screening results of 654 women attending VIA-and-cryotherapy who participated in a sexually transmitted infections prevalence study, at which samples for HPV DNA testing and liquid-based cytology (LBC) were also collected. VIA positives (VIA+) ineligible for cryotherapy, suspected cancers and women with high-grade squamous intraepithelial or worse lesions (HSIL+) on LBC were referred for diagnosis and treatment. Women with negative VIA who were HPV positive (HPV+) and those VIA+ treated with cryotherapy were recalled for another VIA one-year later. The positivity rates of VIA, HPV, atypical squamous cells of undetermined significance or worse cytology abnormalities (LBC ASCUS+) and low-grade squamous intraepithelial or worse lesions (LBC LSIL+) were 9.7%, 42.6%, 13.2% and 5.3%, respectively. HPV testing detected 29 of 31 LSIL+ (93.6%, 95%CI: 78.6-99.2) while VIA only detected 11 (35.6%, 95%CI: 19.2-54.6). The HIV prevalence was 43% (95%CI: 39.2-46.9). HIV positives were at increased risk of being VIA+ (age-adjusted odds ratio: 2.5, 95%CI: 1.5-4.3), HPV+ (3.7, 2.6-5.3) and having LSIL+ (16.3, 4.9-54.8). The ineligibility rates for cryotherapy were 38% (24 of 63 VIA+), and 46% among HIV positives (18 of 39 VIA+). HPV testing was substantially more sensitive than VIA, thus, HPV followed by ablative treatment may be more effective. However, the high ineligibility for cryotherapy highlights the need for improving the assessment of eligibility for ablative treatment and for strengthening colposcopy, particularly in populations with high HIV prevalence.

Mapping Evidence on Management of Cervical Cancer in Sub-Saharan Africa: Scoping Review

Cervical cancer (CC) is the most common viral infection of the reproductive tract and in Sub-Saharan Africa (SSA), its morbidity and mortality rates are high. The aim of this review was to map evidence on CC management in SSA. The scoping review was conducted in accordance with Arksey and O’Malley’s scoping review framework. The review included studies on different aspects of CC management. The review was also done following the steps and guidelines outlined in the PRISMA-Extension for Scoping Reviews (PRISMA-ScR) checklist. The following databases were searched: PubMed, EBSCOhost, Scopus and Cochrane Database of Systematic Review. A total of 1121 studies were retrieved and 49 which were eligible for data extraction were included in the review. The studies were classifiable in 5 groups: 14 (28.57%) were on barriers to CC screening, 10 (20.41%) on factors associated with late-stage presentation at diagnosis, 11 (22.45%) on status of radiotherapy, 4 (8.20%) on status of chemotherapy and 10 (20.41%) on factors associated with high HPV coverage. High HPV vaccine coverage can be achieved using the class school-based strategy with opt-out consent form process. Barriers to CC screening uptake included lack of knowledge and awareness and unavailability of screening services. The reasons for late-stage presentation at diagnosis were unavailability of screening services, delaying whilst using complementary and alternative medicines and poor referral systems. The challenges in chemotherapy included unavailability and affordability, low survival rates, treatment interruption due to stock-outs as well as late presentation. Major challenges on radiotherapy were unavailability of radiotherapy, treatment interruption due to financial constraints, and machine breakdown and low quality of life. A gap in understanding the status of CC management in SSA has been revealed by the study implying that, without full knowledge of the extent of CC management, the challenges and opportunities, it will be difficult to reduce infection, improve treatment and palliative care. Research projects assessing knowledge, attitude and practice of those in immediate care of girls at vaccination age, situational analysis with health professionals and views of patients themselves is important to guide CC management practice.

Bayesian Spatial Modeling of Diabetes and Hypertension: Results from the South Africa General Household Survey

Determining spatial links between disease risk and socio-demographic characteristics is vital in disease management and policymaking. However, data are subject to complexities caused by heterogeneity across host classes and space epidemic processes. This study aims to implement a spatially varying coefficient (SVC) model to account for non-stationarity in the effect of covariates. Using the South Africa general household survey, we study the provincial variation of people living with diabetes and hypertension risk through the SVC model. The people living with diabetes and hypertension risk are modeled using a logistic model that includes spatially unstructured and spatially structured random effects. Spatial smoothness priors for the spatially structured component are employed in modeling, namely, a Gaussian Markov random field (GMRF), a second-order random walk (RW2), and a conditional autoregressive (CAR) model. The SVC model is used to relax the stationarity assumption in which non-linear effects of age are captured through the RW2 and allow the mean effect to vary spatially using a CAR model. Results highlight a non-linear relationship between age and people living with diabetes and hypertension. The SVC models outperform the stationary models. The results suggest significant provincial differences, and the maps provided can guide policymakers in carefully exploiting the available resources for more cost-effective interventions.

Mapping Scientific Productivity Trends and Hotspots in Remdesivir Research Publications: A Bibliometric Study from 2016 to 2021

In response to global efforts to control and exterminate infectious diseases, this study aims to provide insight into the productivity of remdesivir research and highlight future directions. To achieve this, there is a need to summarize and curate evidence from the literature. As a result, this study carried out comprehensive scientific research to detect trends in published articles related to remdesivir using a bibliometric analysis. Keywords associated with remdesivir were used to access pertinent published articles using the Scopus database. A total of 5321 research documents were retrieved, primarily as novel research articles (n = 2440; 46%). The number of publications increased exponentially from 2020 up to the present. The papers published by the top 12 institutions focusing on remdesivir accounted for 25.69% of the overall number of articles. The USA ranked as the most productive country, with 906 documents (37.1%), equivalent to one-third of the global publications in this field. The most productive institution was Icahn School of Medicine, Mount Sinai, in the USA (103 publications). The New England Journal of Medicine was the most cited, with an h-index of 13. The publication of research on remdesivir has gained momentum in the past year. The importance of remdesivir suggests that it needs continued research to help global health organizations detect areas requiring instant action to implement suitable measures. Furthermore, this study offers evolving hotspots and valuable insights into the scientific advances in this field and provides scaling-up analysis and evidence diffusion on remdesivir.

Prevalence and associated risk factors for anaemia amongst pregnant women attending three antenatal clinics in Eswatini

BACKGROUND

 Anaemia is a global health problem affecting about a third of the world's population. In pregnancy, it is a public health concern with consequences for mothers and infants, including maternal death and infant mortality. In low-income countries (LICs), 25% indirect maternal mortality and 30% neonatal deaths are due to anaemia in pregnancy.

AIM

 This study aimed to determine the prevalence and risks associated with anaemia amongst pregnant women attending antenatal clinic (ANC) in three health facilities in Eswatini.

SETTING

 This study was conducted in three health facilities in Eswatini, namely Mankayane, Raleigh Fitkin Memorial (RFM) and Mbabane Hospital.

METHODS

 This cross-sectional study used non-probability sampling in three hospitals of Eswatini, to select 550 pregnant women, aged 15-49 years. Data were collected from January to March 2021, using face-to-face interviews with a structured questionnaire. Logistic regression was used for statistical analysis.

RESULTS

 A total of 550 pregnant women were included in the study. Anaemia prevalence amongst pregnant women was 43.1% with mild, moderate and severe cases of 21.3%; 21.1% and 0.7%, respectively. Prevalence was high amongst women aged 15-19 years (53.3%). Factors associated with anaemia included living in urban areas (odds ratio [OR]: 1.8; confidence interval [CI]: 1.19-2.72), having anaemia 6 months before pregnancy (OR: 4.64; CI: 1.15-18.71), and gestational age at first ANC: third trimester (OR = 10.42; CI: 4.27-25.4) and second trimester (OR: 1.62; CI: 1.02-2.60).

CONCLUSION

 Anaemia remains prevalent amongst pregnant women in Eswatini. A comprehensive anaemia prevention programme would be justified and could lower the country's burden of anaemia.

The economic burden of prostate cancer in Eswatini

Background

Prostate cancer is the fifth cause of cancer mortality among men worldwide. However, there is limited data on costs associated with prostate cancer in low- and middle-income countries particularly in the sub-Saharan region. From a societal perspective, this study aims to estimate the cost of prostate cancer in Eswatini.

Methods

This prevalence–based cost-of-illness study used diagnosis specific data from national registries to estimate costs associated to prostate cancer during 2018. The prevalence-based approach was used employing both top down and bottom up costing approaches. Costs data included health care utilization, transport, sick leave days and premature death.

Results

The total annual cost of prostate cancer was $6.2 million (ranging between $ 4.7 million and 7.8 million estimated with lower and upper bounds). Average cost-per patient for radiotherapy, chemotherapy and other non-medical direct costs (transport and lodging) were the highest cost drivers recording $16,648, $7,498 and $5,959 respectively whilst indirect costs including productive loss due to sick leave and pre-mature mortality was estimated at $58,320 and $113,760 respectively. Cost of managing prostate cancer increased with advanced disease and costs were highest for prostate cancer stages III and IV recording $1.1million, $1.9million respectively.

Conclusions

Prostate cancer is a public health concern in Eswatini, and it imposes significant economic burden to the society. This finding point areas for policy makers to perform cost containment regarding therapeutic procedures for prostate cancer and the need for strategies to increase efficiencies in the health care systems for increased value for health care services.

A Scoping Review on the Epidemiology of Chronic Low Back Pain among Adults in Sub-Saharan Africa

BACKGROUND

The global burden of chronic low back pain (CLBP) is a major concern in public health. Several CLBP epidemiological studies have been conducted in high-income-countries (HICs) with little known in low-and-middle-income-countries (LMICs) due to other competing priorities of communicable diseases. The extrapolation of results of studies from HICs for use in LMICs is difficult due to differences in social norms, healthcare systems, and legislations, yet there is urgent need to address this growing burden. It is against this backdrop that we conducted this review to map the current evidence on the distribution of CLBP in Sub-Saharan Africa (SSA).

METHODS

A comprehensive literature search was conducted from the following databases: PubMed, Google Scholar, Science Direct databases, World Health Organizations library databases, EMBASE, EBSCOhost by searching the following databases within the platform; academic search complete, CINAHL with full text, health sources: nursing/academic and MEDLINE. The title, abstract and the full text screening phases were performed by two independent reviewers with the third reviewer employed to adjudicate discrepancies. The reference list of all included articles was also searched for eligible articles. This scoping review was reported in accordance with the PRISMA extension for scoping reviews (PRISMA-ScR): checklist and explanation, as well as guided by Arksey and O'Malley's scoping review framework. A thematic content analysis was used to give a narrative account of the review.

RESULTS

The electronic search strategy retrieved 21,189 articles. Title/abstract and full text screening only identified 11 articles, which were included in this review. The prevalence of CLBP among the general population ranged from 18.1% to 28.2% and from 22.2% to 59.1% among LBP patients. The prevalence of occupation based CLBP ranged from 30.1% to 55.5%. Identified risk factors for CLBP are multifactorial and included biomechanical, psychological, socioeconomic and lifestyle factors, with psychosocial factors playing a significant role. Hypertension, diabetes mellitus, peptic ulcer disease were the most common comorbidities identified. CLBP disability was significantly associated with psychosocial factors. The management of CLBP in primary care follows the traditional biomedical paradigm and primarily involves pain medication and inconsistent with guidelines.

CONCLUSIONS

There are limited epidemiological data on CLBP in SSA, however, this study concluded that the prevalence and risk factors of CLBP in SSA are comparable to reports in HICs. Considering the projected increase in the burden of CLBP in LMICs extensive research effort is needed to close this knowledge gap.

Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life Years for 29 Cancer Groups From 2010 to 2019: A Systematic Analysis for the Global Burden of Disease Study 2019

IMPORTANCE

The Global Burden of Diseases, Injuries, and Risk Factors Study 2019 (GBD 2019) provided systematic estimates of incidence, morbidity, and mortality to inform local and international efforts toward reducing cancer burden.

OBJECTIVE

To estimate cancer burden and trends globally for 204 countries and territories and by Sociodemographic Index (SDI) quintiles from 2010 to 2019.

EVIDENCE REVIEW

The GBD 2019 estimation methods were used to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life years (DALYs) in 2019 and over the past decade. Estimates are also provided by quintiles of the SDI, a composite measure of educational attainment, income per capita, and total fertility rate for those younger than 25 years. Estimates include 95% uncertainty intervals (UIs).

FINDINGS

In 2019, there were an estimated 23.6 million (95% UI, 22.2-24.9 million) new cancer cases (17.2 million when excluding nonmelanoma skin cancer) and 10.0 million (95% UI, 9.36-10.6 million) cancer deaths globally, with an estimated 250 million (235-264 million) DALYs due to cancer. Since 2010, these represented a 26.3% (95% UI, 20.3%-32.3%) increase in new cases, a 20.9% (95% UI, 14.2%-27.6%) increase in deaths, and a 16.0% (95% UI, 9.3%-22.8%) increase in DALYs. Among 22 groups of diseases and injuries in the GBD 2019 study, cancer was second only to cardiovascular diseases for the number of deaths, years of life lost, and DALYs globally in 2019. Cancer burden differed across SDI quintiles. The proportion of years lived with disability that contributed to DALYs increased with SDI, ranging from 1.4% (1.1%-1.8%) in the low SDI quintile to 5.7% (4.2%-7.1%) in the high SDI quintile. While the high SDI quintile had the highest number of new cases in 2019, the middle SDI quintile had the highest number of cancer deaths and DALYs. From 2010 to 2019, the largest percentage increase in the numbers of cases and deaths occurred in the low and low-middle SDI quintiles.

CONCLUSIONS AND RELEVANCE

The results of this systematic analysis suggest that the global burden of cancer is substantial and growing, with burden differing by SDI. These results provide comprehensive and comparable estimates that can potentially inform efforts toward equitable cancer control around the world.

A Bibliometric Analysis of the Literature on Norovirus Disease from 1991-2021

Norovirus (NoV) is one of the oldest recognized diseases and the leading causal pathogen for acute gastroenteritis (AGE) worldwide. Though numerous studies have been reported on NoV disease, limited research has explored the publication trends in this area. As a result, the objective of this work was to fill the void by conducting a bibliometric study in publication trends on NoV studies as well as discovering the hotspots. The Web of Science central assemblage database was hunted for publications from 1991 to 2021 with “norovirus” in the heading. Microsoft Excel 2016, VOSviewer, R Bibliometrix, and Biblioshiny packages were deployed for the statistical analysis of published research articles. A total of 6021 published documents were identified in the Web of Science database for this thirty-year study period (1991–2021). The analyses disclosed that the Journal of Medical Virology was the leading journal in publications on norovirus studies with a total of 215 published articles, the Journal of Virology was the most cited document with 11,185 total citations. The United States of America (USA) has the most significant productivity in norovirus publications and is the leading country with the highest international collaboration. Analysis of top germane authors discovered that X. Jiang (135) and J. Vinje (119) were the two top relevant authors of norovirus publications. The commonly recognized funders were US and EU-based, with the US emerging as a top funder. This study reveals trends in scientific findings and academic collaborations and serves as a leading-edge model to reveal trends in global research in the field of norovirus research. This study points out the progress status and trends on NoV research. It can help researchers in the medical profession obtain a comprehensive understanding of the state of the art of NoV. It also has reference values for the research and application of the NoV visualization methods. Further, the research map on AGE obtained by our analysis is expected to help researchers efficiently and effectively explore the NoV field.

Improving Timely Access to Diagnostic and Treatment Services for Lung Cancer Patients in KwaZulu-Natal, South Africa: Priority-Setting through Nominal Group Techniques

Background: Lung cancer is the most common cancer worldwide, and it disproportionately affects low-income countries (LICs), where over 58% of cases occur. It is an important public health concern, given its poor healthcare outcomes, yet it is under-researched compared to other cancers. Lung cancer is also very difficult for primary care physicians to diagnose. In many settings, health researchers and clinicians’ resort to engaging in collaborative efforts to determine the best way to implement evidence into routine clinical practice. Methods: This was a grounded theory study comprising seven experts providing oncological services. A Nominal Group Technique (NGT) was used to articulate ideas, identify key problems and reach consensus on the order of priorities for the identified problems. Results: The study findings revealed that access to healthcare facilities providing oncology services and diagnosis was the major barrier to lung cancer care. This was further exacerbated by the manner in which health systems are configured in South Africa. The priorities for the health providers were focused on the lack of specialized resources, whereby referral of patients suspected to have lung cancer was delayed and compounded by the limited availability of treatment. Conclusion: The inadequacy of supportive systems for access to healthcare services negates the government efforts to curb the rising lung cancer-related fatalities in South Africa.

Health trends, inequalities and opportunities in South Africa's provinces, 1990-2019: findings from the Global Burden of Disease 2019 Study

BACKGROUND

Over the last 30 years, South Africa has experienced four 'colliding epidemics' of HIV and tuberculosis, chronic illness and mental health, injury and violence, and maternal, neonatal, and child mortality, which have had substantial effects on health and well-being. Using data from the 2019 Global Burden of Diseases, Injuries and Risk Factors Study (GBD 2019), we evaluated national and provincial health trends and progress towards important Sustainable Development Goal targets from 1990 to 2019.

METHODS

We analysed GBD 2019 estimates of mortality, non-fatal health loss, summary health measures and risk factor burden, comparing trends over 1990-2007 and 2007-2019. Additionally, we decomposed changes in life expectancy by cause of death and assessed healthcare system performance.

RESULTS

Across the nine provinces, inequalities in mortality and life expectancy increased over 1990-2007, largely due to differences in HIV/AIDS, then decreased over 2007-2019. Demographic change and increases in non-communicable diseases nearly doubled the number of years lived with disability between 1990 and 2019. From 1990 to 2019, risk factor burdens generally shifted from communicable and nutritional disease risks to non-communicable disease and injury risks; unsafe sex remained the top risk factor. Despite widespread improvements in healthcare system performance, the greatest gains were generally in economically advantaged provinces.

CONCLUSIONS

Reductions in HIV/AIDS and related conditions have led to improved health since 2007, though most provinces still lag in key areas. To achieve health targets, provincial governments should enhance health investments and exchange of knowledge, resources and best practices alongside populations that have been left behind, especially following the COVID-19 pandemic.

The global burden of adolescent and young adult cancer in 2019: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

In estimating the global burden of cancer, adolescents and young adults with cancer are often overlooked, despite being a distinct subgroup with unique epidemiology, clinical care needs, and societal impact. Comprehensive estimates of the global cancer burden in adolescents and young adults (aged 15-39 years) are lacking. To address this gap, we analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, with a focus on the outcome of disability-adjusted life-years (DALYs), to inform global cancer control measures in adolescents and young adults.

METHODS

Using the GBD 2019 methodology, international mortality data were collected from vital registration systems, verbal autopsies, and population-based cancer registry inputs modelled with mortality-to-incidence ratios (MIRs). Incidence was computed with mortality estimates and corresponding MIRs. Prevalence estimates were calculated using modelled survival and multiplied by disability weights to obtain years lived with disability (YLDs). Years of life lost (YLLs) were calculated as age-specific cancer deaths multiplied by the standard life expectancy at the age of death. The main outcome was DALYs (the sum of YLLs and YLDs). Estimates were presented globally and by Socio-demographic Index (SDI) quintiles (countries ranked and divided into five equal SDI groups), and all estimates were presented with corresponding 95% uncertainty intervals (UIs). For this analysis, we used the age range of 15-39 years to define adolescents and young adults.

FINDINGS

There were 1·19 million (95% UI 1·11-1·28) incident cancer cases and 396 000 (370 000-425 000) deaths due to cancer among people aged 15-39 years worldwide in 2019. The highest age-standardised incidence rates occurred in high SDI (59·6 [54·5-65·7] per 100 000 person-years) and high-middle SDI countries (53·2 [48·8-57·9] per 100 000 person-years), while the highest age-standardised mortality rates were in low-middle SDI (14·2 [12·9-15·6] per 100 000 person-years) and middle SDI (13·6 [12·6-14·8] per 100 000 person-years) countries. In 2019, adolescent and young adult cancers contributed 23·5 million (21·9-25·2) DALYs to the global burden of disease, of which 2·7% (1·9-3·6) came from YLDs and 97·3% (96·4-98·1) from YLLs. Cancer was the fourth leading cause of death and tenth leading cause of DALYs in adolescents and young adults globally.

INTERPRETATION

Adolescent and young adult cancers contributed substantially to the overall adolescent and young adult disease burden globally in 2019. These results provide new insights into the distribution and magnitude of the adolescent and young adult cancer burden around the world. With notable differences observed across SDI settings, these estimates can inform global and country-level cancer control efforts.

Knowledge, attitude and practice towards cervical cancer prevention among mothers of girls aged between 9 and 14 years: a cross sectional survey in Zimbabwe

Background

Cervical cancer (CC) morbidity and mortality is still high in developing countries like Zimbabwe. Treatment for CC is out of reach for many women, hence the need to maximise on prevention which mainly includes screening and administering human papillomavirus (HPV) vaccine. Knowledge about CC prevention is a prerequisite for utilisation of all the available options for CC prevention, yet little is known about its levels and the corresponding attitudes and practices on cancer prevention methods within the society.

Methods

A cross sectional survey was done to assess knowledge, attitude and practice (KAP) on CC prevention among mothers of girls aged between 9 and 14 years in Zimbabwe as well as factors explaining the KAP. Four hundred and six mothers participate. Descriptive and inferential statistics (binary logistic regression and Chi-Square test of association) were applied to determine participant characteristics with KAP using STATA version 16 software.

Findings

Overall KAP of cervical cancer prevention is in a poor state. The knowledge was poor with 24% being able to say CC is caused by HPV; the attitude is negative with 58% being of the opinion that CC is caused by witchcraft and it is a death sentence, while the bad practices of relying only on traditional means were being practiced. Factors associated with knowledge are: not having medical aid (odds: 0.17, 95%CI: 0.05–0.59, p = 0.005) and high levels of education (secondary level odds: 4.20; 95%CI: 2.25–7.84 p < 0.001 and tertiary odds: 7.75; 95%CI: 2.04–29.45, p-value: 0.003 compared to primary education). Attitude towards CC management was driven by levels of education (secondary level odds: 0.39, 95%CI: 0.20–0.78, p = 0.007 and tertiary odds: 0.12, 95%CI: 0.04–0.33, p < 0.001), the same factor increases odds of good practice (secondary odds: 3.78, 95%CI: 1.99–7.18, p < 0.001 and tertiary odds: 3.78, 95%CI: 1.99–7.18, p < 0.001). On the other hand, HPV vaccine knowledge was also very moderate (with majority of mothers not knowing the right age of vaccination; vaccine acceptability was high (90%), but uptake was very low (8% had their daughter vaccinated).

Conclusion

KAP about CC prevention was poor with factors necessary for improvement of KAP identified as education, medical insurance coverage. Making health education easily accessible in schools, primary health facilities and various media platforms will help to address the myths on causes of CC and how it can be treated. Health education and availability of free screening services and free vaccine will improve CC prevention out outcomes.

The social burden experienced by families caring for members living with cancer in KwaZulu-Natal, South Africa

BACKGROUND

Cancer is a global public health problem and it affects people in different ways. Family caregivers (FCs) play an essential role in caring for patients with cancer, and thus, they experience many caregiver burdens that go unnoticed.

AIM

This research study explored the social burden that families experience in providing care to their family members living with cancer.

SETTING

This study was conducted in Durban and Pietermaritzburg, cities located in KwaZulu-Natal, South Africa.

METHODS

This was a qualitative study using the interpretative phenomenological approach that was ideal for understanding FCs subjective perspectives on their cancer caregiving experience. Data saturation were reached at 20 in-depth interviews.

RESULTS

Two major themes culminated from the data analysis; dynamics of a cancer diagnosis and psychosocial impact of a cancer diagnosis with respective sub-themes. Themes centred around the relational impact of a cancer diagnosis with FCs experiencing a shift in this dynamic and a disturbance to normality in social life. Social support systems were found to play a meaningful role in mitigating the impact of a cancer diagnosis with financial, psychosocial and educational support considered essential needs.

CONCLUSION

Cancer caregiving is a challenging task that also presents opportunities for strengthening family bonds as they evolve in new paths. A family-centred care approach is recommended as a form of social support with further collaboration with health care providers for guided patient care. If the needs of FCs are addressed accordingly through health care policies and interventions, FCs may be able to provide better care and support for their family members with cancer and thus positively impact cancer survivorship.

Facilitating factors and barriers to kangaroo mother care utilisation in low- and middle-income countries: A scoping review

BACKGROUND

Kangaroo mother care (KMC) has been widely adopted in low-and middle-income countries (LMICs) to minimise low birthweight infants' (LBWIs) adverse outcomes. However, the burden of neonatal and child mortality remains disproportionately high in LMICs.

AIM

Thus, this scoping review sought to map evidence on the barriers, challenges and facilitators of KMC utilisation by parents of LBWIs (parent of low birthweight infant [PLBWI]) in LMICs.

METHODS

We searched for studies conducted in LMICs and published in English between January 1990 and August 2020 from SciELO, Google Scholar, JSTOR, LILACS, Academic search complete, PubMed, CINAHL with full text, and Medline databases. We adopted Arksey and O'Malley's framework for conducting scoping reviews. Potential studies were exported to Endnote X7 reference management software for abstract and full article screening. Two independent reviewers did a parallel abstract and full article screening using a standardised form. The results were analysed using thematic content analysis.

RESULTS

We generated 22 040 studies and after duplicate removal, 42 studies were eligible for full-text screening and 22 studies, most form sub-Saharan Africa, were included in the content analysis. Eight themes emerged from the analysis: access, buy-in, co-ordination and collaboration, medical issues, motivation, social support-gender obligation and empowerment, time and timing and traditional/cultural norms.

CONCLUSION

Identifying factors affecting KMC may optimise KMC utilisation. Additional studies aiming at identifying influencing factors that affect KMC utilisation amongst PLBWIs' in LMICs need to be conducted to provide evidence-based strategies to enhance practice, inform policy and decision-makers in KMC utilisation amongst the PLBWIs in LMICs and beyond.

Establishing and Evaluating Cancer Surveillance System in KwaZulu-Natal, South Africa

Background:

The increasing cancer burden remains a public health challenge. Quality and accurate population data is important to improve cancer control, screening, and treatment programmes for the sub-Saharan Africa region.

Aim:

The aim of this study was to establish hospital-based cancer surveillance system, thereby reporting the burden that cancer diagnosis and treatment place on 3 hospitals – an approach of health systems strengthening.

Methods:

A hospital-based cancer surveillance was established in 3 public health facilities that provide oncology services in KwaZulu-Natal. An active method was used for finding cancer cases. The cancer surveillance database was evaluated according to the criteria recommended for cancer registries. Analyses of data included descriptive and crude incidence rates.

Results:

A total of 2307 newly diagnosed cancer cases were reported in 2018, with a majority from Inkosi Albert Luthuli Central hospital (65.3%), followed by Greys hospital (30.8%) and then Addington hospital (3.94%). Most of the cancer cases were from the 2 major urban areas of the province (eThekwini and uMgungundlovu district). The most commonly diagnosed cancers from all combined 3 facilities for both sexes were breast, cervix, colorectal, Kaposi Sarcoma, and lung. Approximately half of the cancer cases had no staging, and 12.8% of the cases were diagnosed at stage 4. The mostly prescribed treatments for the patients were radiotherapy and chemotherapy.

Conclusions:

Based on our hospital-based surveillance, cancer burden is high in the 3 facilities. Strengthening cancer screening and diagnostic policies and procedures that will allow expansion of accurate cancer surveillance system is essential in KwaZulu-Natal and South Africa as a whole.

Spatial Distribution of Cancer Cases Seen in Three Major Public Hospitals in KwaZulu-Natal, South Africa

Background:

Noncommunicable diseases (NCDs) like cancer are posing a challenge in the health system especially in low- and middle-income countries (LMICs). In South Africa, cancer is under-reported due to the lack of a comprehensive cancer surveillance system. The limited knowledge on the extent of cancer burden has led to inaccurate allocation of public health resources. The aim of this study was to describe cancer incidence and spatial distribution of cancer cases seen at 3 main public oncology facilities in KwaZulu-Natal.

Methods:

In this retrospective study, cases of cancer observed from year 2015 to 2017 were extracted from medical records. The crude incidence rate was estimated for the total cancer cases and for different type of cancer reported over that period. Age-standardised incidence rates (ASR) per 100 000 was calculated per year using age groups and sex according to the district population data of KwaZulu-Natal. The comparisons of cancer diagnosed incidences were made between 11 districts using the ASR. Choropleth spatial maps and Moran’s Index were used to assess the ASR cancer spatial distribution along with geographical patterns among the districts. One sample chi-square test was used to assess the significant increase/decrease over time.

Results:

The study lost numerous cases due to incompleteness. A total of 4909 new cases were diagnosed with cancer during 2015 to 2017, 62% of which were female. Both uMgungundlovu and eThekwini districts had the highest ASR among district municipalities of KwaZulu-Natal for both male and female (83.6 per 100 000 per men year for men, 158.2 per 100 000 women per year, and 60.1 per 100 000 men per year and 96.9 per 100 000 women per year, respectively). Random distribution of reported cancer cases in KwaZulu-Natal was observed with a high concentration being in and around 2 metropolitan districts. Spatial variation showed a significant difference from year to year between the districts with the random spatial distribution. Overall, there was a significant decline of cancer incidences observed from 2015 to 2017 (P < .05) in the province.

Conclusion:

The overall cancer incidence in the study shows that female cancers (breast and cervical) are still on the rise and still need to be given priority as they were most prevalent in KwaZulu-Natal. Spatial analysis (choropleth maps) was used to show a pattern of higher concentration of cancer incidence in the north-western parts of the province.

Mapping evidence on management of cervical cancer in sub-Saharan Africa: scoping review protocol

BACKGROUND

Cancer is a non-communicable disease and is the number 2 leading cause of death globally. Among all cancers, cervical cancer is the number 1 killer of women in low-income countries (LICs). Cervical cancer is a well understood preventable cancer. The rates of cervical cancer are very varied and inversely proportional to the effectiveness of disease management policies. Management of cervical cancer includes prevention, screening, diagnosis and treatment. The main objective of this scoping review is to map the evidence on cervical cancer management in sub-Saharan Africa (SSA) to understand the coverage of cervical cancer prevention and treatment services and provide an opportunity to generate knowledge on the risk factors, attitudes and practices extendable globally.

METHODS AND ANALYSIS

This review will be guided by Arksey and O'Malley's framework recommended for conducting scoping review studies. The Preferred Reporting Items for Systematic Review and Meta-Analysis extension for Scoping Reviews (PRISMA-Scr) checklist will also be completed to ensure that the review adheres to the sound methodological rigour acceptable for scoping review studies. The following electronic databases will be searched for potentially eligible articles: PubMed, Ebsco Host, Scopus and Cochrane Database of Systematic Reviews. Study screening procedures recommended by Higgins and Deeks will be followed. A narrative synthesis will be used, with data synthesised and interpreted using sifting, charting and sorting based on themes and key issues.

DISCUSSION

Cervical cancer can become a disease of the past with a proper control strategy in place. It is therefore imperative to map available evidence on the management of cervical cancer to inform policy and advocacy action. More knowledge on the status quo will guide policymakers in ensuring cancer management guiding policies are formulated/updated/revised accordingly.

Subnational mapping of HIV incidence and mortality among individuals aged 15-49 years in sub-Saharan Africa, 2000-18: a modelling study

BACKGROUND

High-resolution estimates of HIV burden across space and time provide an important tool for tracking and monitoring the progress of prevention and control efforts and assist with improving the precision and efficiency of targeting efforts. We aimed to assess HIV incidence and HIV mortality for all second-level administrative units across sub-Saharan Africa.

METHODS

In this modelling study, we developed a framework that used the geographically specific HIV prevalence data collected in seroprevalence surveys and antenatal care clinics to train a model that estimates HIV incidence and mortality among individuals aged 15-49 years. We used a model-based geostatistical framework to estimate HIV prevalence at the second administrative level in 44 countries in sub-Saharan Africa for 2000-18 and sought data on the number of individuals on antiretroviral therapy (ART) by second-level administrative unit. We then modified the Estimation and Projection Package (EPP) to use these HIV prevalence and treatment estimates to estimate HIV incidence and mortality by second-level administrative unit.

FINDINGS

The estimates suggest substantial variation in HIV incidence and mortality rates both between and within countries in sub-Saharan Africa, with 15 countries having a ten-times or greater difference in estimated HIV incidence between the second-level administrative units with the lowest and highest estimated incidence levels. Across all 44 countries in 2018, HIV incidence ranged from 2·8 (95% uncertainty interval 2·1-3·8) in Mauritania to 1585·9 (1369·4-1824·8) cases per 100 000 people in Lesotho and HIV mortality ranged from 0·8 (0·7-0·9) in Mauritania to 676·5 (513·6-888·0) deaths per 100 000 people in Lesotho. Variation in both incidence and mortality was substantially greater at the subnational level than at the national level and the highest estimated rates were accordingly higher. Among second-level administrative units, Guijá District, Gaza Province, Mozambique, had the highest estimated HIV incidence (4661·7 [2544·8-8120·3]) cases per 100 000 people in 2018 and Inhassunge District, Zambezia Province, Mozambique, had the highest estimated HIV mortality rate (1163·0 [679·0-1866·8]) deaths per 100 000 people. Further, the rate of reduction in HIV incidence and mortality from 2000 to 2018, as well as the ratio of new infections to the number of people living with HIV was highly variable. Although most second-level administrative units had declines in the number of new cases (3316 [81·1%] of 4087 units) and number of deaths (3325 [81·4%]), nearly all appeared well short of the targeted 75% reduction in new cases and deaths between 2010 and 2020.

INTERPRETATION

Our estimates suggest that most second-level administrative units in sub-Saharan Africa are falling short of the targeted 75% reduction in new cases and deaths by 2020, which is further compounded by substantial within-country variability. These estimates will help decision makers and programme implementers expand access to ART and better target health resources to higher burden subnational areas.

Mapping evidence on the distribution of the costs associated with cancer of prostate, cervix, and female breast in the sub-Saharan Africa: protocol for a scoping review

BACKGROUND

Despite the well-documented information on cancer prevention and management, among noncommunicable diseases (NCDs), globally, cancer continues to be the second leading cause of morbidity and mortality with devastating economic consequences. The burden is disproportionately more among developing countries and the extent of evidence available on the economic consequences (direct and indirect costs) of cancer remains unknown in low-income countries particularly in the sub-Saharan region. Understanding the costs of illness is important to inform decision-making on setting up health care policies and informing economic evaluation of interventions. This study aims to map evidence on the distribution of the economic burden (direct and indirect costs) associated with prevention, diagnosis, and treatment of three predominant cancers: prostate, cervix, and female breast in the sub-Saharan Africa.

METHODS

This scoping review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR), and will be conducted following Arksey and O'Malley's framework. We will search PubMed/MEDLINE, Web of Science, CINHAL (via EBSCOhost platform), Science Direct, Cochrane Database of Systematic Reviews, Africa-Wide Information, Google Scholar, and WHO Library. We will perform hand-searching of the reference lists of included studies and other relevant documents. Two reviewers will independently screen all citations, full-text articles, and abstract data. We will include primary studies from all study designs reporting costs associated with prevention, diagnosis and treatment of prostate, cervical, and breast cancers in the sub-Saharan region. Data analysis will involve quantitative (e.g., frequencies) and qualitative (e.g., thematic analysis) methods. A narrative summary of findings will be presented.

DISCUSSION

This review will map the extent of information available on the economic burden (direct and indirect costs) of prostate, cervical, and breast cancers in the sub-Saharan region. Further guidance for future research in the subject area will be discussed.

The economic burden of cervical cancer in Eswatini: Societal perspective

Background

Cervical cancer imposes considerable economic burden on societies and individuals. There is lack of evidence regarding this from the developing world and particularly from sub-Saharan Africa. Therefore, the study aimed to estimate the societal costs of cervical cancer in Eswatini.

Materials and methods

The cost of illness study (CoI) was applied using national specific clinical and registry data from hospitals, registries and reports to determine the prevalence of cervical intraepithelial neoplasia (CIN) and cervical cancer in Eswatini in 2018. Cost data included direct medical costs (health care utilization in inpatient and outpatient care), direct non-medical costs (patient costs for traveling) and indirect costs based on productivity loss due to morbidity (patient time during diagnosis and treatment) and premature mortality.

Results

The estimated total annual cost for cervical cancer was $19 million (ranging between $14 million and $24 million estimated with lower and upper bounds). Direct cost represented the majority of the costs at 72% ($13.7 million) out of which total pre-cancerous treatment costs accounted for 0.7% ($94,161). The management of invasive cervical cancer was the main cost driver with costs attributable to treatment for FIGO III and FIGO IV representing $1.7 million and $8.7 million respectively. Indirect costs contributed 27% ($5.3 million) out of which productivity loss due to premature mortality represented the majority at 67% ($3.5 million).

Conclusion

The economic burden of cervical cancer in Eswatini is substantial. National public health prevention strategies with prophylactic HPV vaccine and screening for cervical lesions should therefore be prioritized to limit the extensive costs associated with cervical cancer.

An ethnographic study exploring the experiences of patients living with cancer illness in support group settings in KwaZulu-Natal, South Africa

Background

The major strength of support groups stems from their ability to help patients manage their health within and outside the traditional hospital settings. Despite the known benefits of support groups for people living with cancer, ethnographic studies documenting the cancer patients’ experiences of living with cancer within the support group contexts in KwaZulu-Natal are scarce.

Aim

The aim of this study was to examine the experiences of patients living with cancer within a support group setting.

Setting

The study setting was support groups in KwaZulu- Natal, South Africa.

Materials and Methods

This study was conducted using, participant observation, focus group discussions and in-depth interviews. Data were generated over a 3-month period. Purposive sampling was used to identify the information-rich participants. Thematic data analysis was performed in order to obtain insights into the collective meaning of data generated.

Results

Participants viewed the support group settings as creating an environment with a unique sense of community. This was in contrast with the sense of isolation, rejection and lack of empowering knowledge on cancer, often experienced outside these contexts. Moreover, the support groups were lauded for facilitating positive relationships with family and friends and providing a safe space for members to freely express their emotions.

Conclusion

Psychosocial support provided by support groups can help to ameliorate the distress caused by cancer diagnosis and its treatment; however, these support groups are still few and far in between. Therefore, there should be a greater investment in establishing support groups.

Measuring universal health coverage based on an index of effective coverage of health services in 204 countries and territories, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Achieving universal health coverage (UHC) involves all people receiving the health services they need, of high quality, without experiencing financial hardship. Making progress towards UHC is a policy priority for both countries and global institutions, as highlighted by the agenda of the UN Sustainable Development Goals (SDGs) and WHO's Thirteenth General Programme of Work (GPW13). Measuring effective coverage at the health-system level is important for understanding whether health services are aligned with countries' health profiles and are of sufficient quality to produce health gains for populations of all ages.

METHODS

Based on the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we assessed UHC effective coverage for 204 countries and territories from 1990 to 2019. Drawing from a measurement framework developed through WHO's GPW13 consultation, we mapped 23 effective coverage indicators to a matrix representing health service types (eg, promotion, prevention, and treatment) and five population-age groups spanning from reproductive and newborn to older adults (≥65 years). Effective coverage indicators were based on intervention coverage or outcome-based measures such as mortality-to-incidence ratios to approximate access to quality care; outcome-based measures were transformed to values on a scale of 0-100 based on the 2·5th and 97·5th percentile of location-year values. We constructed the UHC effective coverage index by weighting each effective coverage indicator relative to its associated potential health gains, as measured by disability-adjusted life-years for each location-year and population-age group. For three tests of validity (content, known-groups, and convergent), UHC effective coverage index performance was generally better than that of other UHC service coverage indices from WHO (ie, the current metric for SDG indicator 3.8.1 on UHC service coverage), the World Bank, and GBD 2017. We quantified frontiers of UHC effective coverage performance on the basis of pooled health spending per capita, representing UHC effective coverage index levels achieved in 2019 relative to country-level government health spending, prepaid private expenditures, and development assistance for health. To assess current trajectories towards the GPW13 UHC billion target-1 billion more people benefiting from UHC by 2023-we estimated additional population equivalents with UHC effective coverage from 2018 to 2023.

FINDINGS

Globally, performance on the UHC effective coverage index improved from 45·8 (95% uncertainty interval 44·2-47·5) in 1990 to 60·3 (58·7-61·9) in 2019, yet country-level UHC effective coverage in 2019 still spanned from 95 or higher in Japan and Iceland to lower than 25 in Somalia and the Central African Republic. Since 2010, sub-Saharan Africa showed accelerated gains on the UHC effective coverage index (at an average increase of 2·6% [1·9-3·3] per year up to 2019); by contrast, most other GBD super-regions had slowed rates of progress in 2010-2019 relative to 1990-2010. Many countries showed lagging performance on effective coverage indicators for non-communicable diseases relative to those for communicable diseases and maternal and child health, despite non-communicable diseases accounting for a greater proportion of potential health gains in 2019, suggesting that many health systems are not keeping pace with the rising non-communicable disease burden and associated population health needs. In 2019, the UHC effective coverage index was associated with pooled health spending per capita (r=0·79), although countries across the development spectrum had much lower UHC effective coverage than is potentially achievable relative to their health spending. Under maximum efficiency of translating health spending into UHC effective coverage performance, countries would need to reach $1398 pooled health spending per capita (US$ adjusted for purchasing power parity) in order to achieve 80 on the UHC effective coverage index. From 2018 to 2023, an estimated 388·9 million (358·6-421·3) more population equivalents would have UHC effective coverage, falling well short of the GPW13 target of 1 billion more people benefiting from UHC during this time. Current projections point to an estimated 3·1 billion (3·0-3·2) population equivalents still lacking UHC effective coverage in 2023, with nearly a third (968·1 million [903·5-1040·3]) residing in south Asia.

INTERPRETATION

The present study demonstrates the utility of measuring effective coverage and its role in supporting improved health outcomes for all people-the ultimate goal of UHC and its achievement. Global ambitions to accelerate progress on UHC service coverage are increasingly unlikely unless concerted action on non-communicable diseases occurs and countries can better translate health spending into improved performance. Focusing on effective coverage and accounting for the world's evolving health needs lays the groundwork for better understanding how close-or how far-all populations are in benefiting from UHC.

Lung cancer awareness and palliative care interventions implemented in low-and middle-income countries: a scoping review

BACKGROUND

Lung cancer is the most diagnosed cancer worldwide. In low- and middle-income countries (LMICs), lung cancer is often diagnosed at a late stage due to poor knowledge and awareness of its signs and symptoms. Increasing lung cancer awareness is likely to reduce the diagnosis and treatment delays. The implementation of early palliative care has also been reported to improve a patient's quality of life, and even survival. The aim of this scoping review was to map evidence on lung cancer awareness and palliative care interventions implemented in sub-Saharan Africa (SSA) and other LMICs.

METHODS

This scoping review was guided by Arksey and O'Malley's framework. Databases such as the EBSCOhost, PubMed, Science Direct, Google Scholar, World Health Organization (WHO) library and grey literature were used to perform systematic searches of relevant articles. The methodological quality assessment of included primary studies was assessed using the Mixed Method Appraisal Tool (MMAT). NVivo version 10 software was used to perform the thematic content analysis of the included studies.

RESULTS

A total number of screened articles was 2886, with 236 meeting the eligibility criteria and 167 further excluded following abstract screening. Sixty-nine (69) articles qualified for full-article screening and 9 were selected for detailed data extraction and methodological quality assessment. Of the included nine studies, eight described at least one lung cancer warning signs and symptoms, while one described the effectiveness of palliative care for lung cancer. Eight articles recognized the level of lung cancer knowledge, risk factors awareness of warning signs and symptoms in LMICs, mostly Africa and Asia.

CONCLUSIONS

Most of the participants were aware of tobacco use as the major risk factor for lung cancer but lacked knowledge on the other pre-disposing risk factors. Evidence on palliative care is scarce, therefore, awareness interventions packaged with evidence on the value of timely access to palliative care services in improving the quality of life of the lung cancer patients and their families, are required.

Mapping geographical inequalities in access to drinking water and sanitation facilities in low-income and middle-income countries, 2000-17

BACKGROUND

Universal access to safe drinking water and sanitation facilities is an essential human right, recognised in the Sustainable Development Goals as crucial for preventing disease and improving human wellbeing. Comprehensive, high-resolution estimates are important to inform progress towards achieving this goal. We aimed to produce high-resolution geospatial estimates of access to drinking water and sanitation facilities.

METHODS

We used a Bayesian geostatistical model and data from 600 sources across more than 88 low-income and middle-income countries (LMICs) to estimate access to drinking water and sanitation facilities on continuous continent-wide surfaces from 2000 to 2017, and aggregated results to policy-relevant administrative units. We estimated mutually exclusive and collectively exhaustive subcategories of facilities for drinking water (piped water on or off premises, other improved facilities, unimproved, and surface water) and sanitation facilities (septic or sewer sanitation, other improved, unimproved, and open defecation) with use of ordinal regression. We also estimated the number of diarrhoeal deaths in children younger than 5 years attributed to unsafe facilities and estimated deaths that were averted by increased access to safe facilities in 2017, and analysed geographical inequality in access within LMICs.

FINDINGS

Across LMICs, access to both piped water and improved water overall increased between 2000 and 2017, with progress varying spatially. For piped water, the safest water facility type, access increased from 40·0% (95% uncertainty interval [UI] 39·4-40·7) to 50·3% (50·0-50·5), but was lowest in sub-Saharan Africa, where access to piped water was mostly concentrated in urban centres. Access to both sewer or septic sanitation and improved sanitation overall also increased across all LMICs during the study period. For sewer or septic sanitation, access was 46·3% (95% UI 46·1-46·5) in 2017, compared with 28·7% (28·5-29·0) in 2000. Although some units improved access to the safest drinking water or sanitation facilities since 2000, a large absolute number of people continued to not have access in several units with high access to such facilities (>80%) in 2017. More than 253 000 people did not have access to sewer or septic sanitation facilities in the city of Harare, Zimbabwe, despite 88·6% (95% UI 87·2-89·7) access overall. Many units were able to transition from the least safe facilities in 2000 to safe facilities by 2017; for units in which populations primarily practised open defecation in 2000, 686 (95% UI 664-711) of the 1830 (1797-1863) units transitioned to the use of improved sanitation. Geographical disparities in access to improved water across units decreased in 76·1% (95% UI 71·6-80·7) of countries from 2000 to 2017, and in 53·9% (50·6-59·6) of countries for access to improved sanitation, but remained evident subnationally in most countries in 2017.

INTERPRETATION

Our estimates, combined with geospatial trends in diarrhoeal burden, identify where efforts to increase access to safe drinking water and sanitation facilities are most needed. By highlighting areas with successful approaches or in need of targeted interventions, our estimates can enable precision public health to effectively progress towards universal access to safe water and sanitation.

Patterns, trends, and factors associated with contraceptive use among adolescent girls in Zambia (1996 to 2014): a multilevel analysis

BACKGROUND

Despite high levels of pregnancy and childbearing among adolescents in Africa, contraceptive use remains low. Examining variations in contraceptive use among adolescent girls is vital for informing programs to improve contraceptive utilisation among this segment of the population. This study aimed to examine the patterns, trends, and factors associated with contraceptive use among adolescents in Zambia over the period 1996-2014.

METHODS

The study involved an analysis of data from 1996, 2001/2, 2007 and 2013/14 Zambia Demographic and Health Surveys focusing on adolescent girls aged 15-19 years. Analysis entailed descriptive statistics and estimation of multilevel logistic regression models examining variations in contraceptive use among adolescent girls over time. Estimates with p-values less than 0.05 were considered statistically significant.

RESULTS

Results showed that contraceptive use remains low and ranged from 7.6% in 1996 to 10.9% in 2013/14, reflecting a change of 3.3 percentage points over 18 years. Over the 18 years, contraceptive use was significantly associated with age, level of education, and marital status. Older adolescent girls and those with higher levels of education were significantly more likely to use contraception compared to younger ones and those with lower levels of education. Although initially significant (AOR 0.556, 95% CI 0.317, 0.974 in 1996), rural-urban differences disappeared between 2001/2 and 2007 but re-emerged in 2013/14 (AOR 0.654, 95% CI 0.499, 0.859). Across all survey years, adolescents who were married or living with a partner were significantly more likely to use contraceptives compared to those who were not married.

CONCLUSIONS

The findings suggest the need for targeted interventions to improve contraceptive use among sexually active adolescent girls in the country in general, and those who are disadvantaged in particular.

Facilitating factors and barriers to accessibility and utilization of kangaroo mother care service among parents of low birth weight infants in Mangochi District, Malawi: a qualitative study

Background

Kangaroo Mother Care (KMC) is one of the interventions widely used in low-income countries to manage Low Birth Weight Infants (LBWIs), a global leading cause of neonatal and child mortality. LBWI largely contributes to neonatal mortality in Malawi despite the country strengthening and implementing KMC, nationwide, to enhance the survival of LBWIs. This qualitative study aimed to assess the facilitating factors and barriers to accessibility and utilization of KMC service by the parent of low birth weight infants (PLBWIs) in Mangochi District, Malawi.

Methods

Two focused group discussions assessed factors facilitating and hindering the accessibility and utilization of KMC service were conducted in April 2018 that reached out to (N = 12) participants; (n:6) PLBWI practicing KMC at Mangochi district hospital (MDH) referred from four health facilities and (n:6) high-risk pregnant mothers (HRPMs) visiting antenatal care (ANC) clinic at MDH. The availability of KMC at MDH was assessed using KMC availability checklist. The study used purposive, convenient and simple random sampling to identify eligible participants. Thematic analysis was used to analyze the findings.

Results

Sixteen themes emerged on facilitating factors and barriers to accessibility and utilization of KMC service by the PLBWIs. The identified themes included; availability of KMC providers, social factor (social support and maternal love), timing of KMC information, knowledge on KMC, health linkage systems, recognition of LBWIs, safety on the use of KMC, preference of LBWI’s care practice, lived experience on KMC practice, KMC expert clients, perceived causes of LBWI births, cultural/traditional factors, religious beliefs, health-seeking behavior, women empowerment and quality of care.

Conclusions

Although KMC was available in some of the health facilities, integration of KMC messages in ANC guidelines, community awareness and in sensitization of any health intervention may enhance KMC accessibility and utilization by the targeted population.

The interplay of HIV and human papillomavirus-related cancers in sub-Saharan Africa: scoping review

BACKGROUND

People living with HIV (PLHIV) are at a high risk of developing HPV-related cancers. HPV-related malignancies occur frequently and/or are high among PLHIV, with cervical cancer as a designated AIDS-defining condition. We aimed to explore the evidence on the interplay of HIV and HPV-related cancers in sub-Saharan Africa (SSA).

METHODS

The scoping review was guided by Arksey and O'Malley's framework. We searched for literature from the following databases: PubMed; World Health Organization (WHO) Library; Science Direct; Google Scholar and EBSCOhost (Academic search complete, Health Source: Nursing/Academic Edition, CINAHL). Studies reporting on evidence HIV and HPV-related cancers interplay in SSA were eligible for inclusion in this review. The Mixed Methods Appraisal Tool (MMAT) tool was used to assess the risk of bias of the included studies. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used for reporting the search results. Thematic analysis used to reveal the emerging themes from the included studies.

RESULTS

A total of 74 potentially eligible articles were screened. Of these, nine (7 reviews, 1 transversal case controls, and 1 quantitative study) were eligible for data extraction. The studies reported about a total of 16,351 participants in different settings. The nine included studies showed evidence of cervical cancer among HIV-infected women and distribution of HPV infection and cervical abnormalities among HIV-positive individuals. In the four studies generalizing about HIV and anal cancer, only one reported about HPV. Two studies generally reported about HIV and head and neck cancers and one reported about interaction of HIV with vaginal cancer, vulvar cancer, and penile cancer, respectively.

CONCLUSION

HIV positivity is associated with increased prevalence of HPV infection on different anatomic sites, which will result in increased burden of HPV-related cancers among PLHIV. Furthermore, primary studies with robust study designs aimed at investigating the risk developing HPV-related cancers among PLHIV are recommended. Systematic review registration: PROSPERO CRD42017062403.

Health systems influence on the pathways of care for lung cancer in low- and middle-income countries: a scoping review

Background

Globally, lung cancer is the most common cancer and cause of cancer-related deaths, responsible for nearly one in five deaths. Many health systems in low- and middle-income countries, including sub-Saharan Africa have weak organizational structure, which results in delayed lead time for lung cancer patient care continuum from diagnosis to palliative care.

Aim

To map evidence on the health systems issues impacting on the delays in timely lung cancer care continuum from diagnosis to palliative care in LMICs, including sub-Saharan Africa.

Methods

A scoping review was performed following the method of Arksey and O’Malley. Systematic searches were performed using EBSCOhost platform, a keyword search from the following electronic databases were conducted: PubMed/MEDLINE, Google Scholar, Science Direct, World Health Organization (WHO) library, and grey literature. The screening was guided by the inclusion and exclusion criteria. The quality of the included studies was determined by Mixed Method Appraisal Tool (MMAT).

Results

A total of 2886 articles were screened, and 236 met the eligibility criteria for this scoping review study. Furthermore, 155 articles were also excluded following abstract screening. Eighty-one articles were selected for full-article screening by two researchers with 10 being selected for independent detailed data extraction for synthesis. These studies were also subjected to methodological quality assessment. All included studies were conducted in LMICs mostly Asia, the Middle East, and Latin America and published between January 2008 and June 2018. The ten included studies described at least one interval in lung cancer care.

Conclusions

Reducing wait time across this care continuum is needed to improve easy access to healthcare, quality care, survival and patient outcomes, as many patients still face longer wait times for diagnosis and treatment of lung cancer than recommended in several healthcare settings. A multidisciplinary team approach will help to reduce wait time and ensure that all patients receive appropriate care. Interventions are needed to address delays in lung cancer care in LMICs. Health-care providers at all levels of care should be educated and equipped with skills to identify lung cancer symptoms and perform or refer for appropriate diagnostic tests.
