Integrated primary health care in low- and middle-income countries: a double challenge

CHD-related/specific mortality of 3.17 million people in a transitioning region: trends, risk factors, and prevention

BACKGROUND

Demographic shifts cause uncertain changes in the burden of coronary heart disease (CHD) in transitioning regions. We aimed to analyze the trends of CHD burden and its risk factors in Pudong, Shanghai, and explore prevention strategies for transitioning regions.

METHODS

We analyzed CHD-related and CHD-specific deaths in Pudong from 2005 to 2020, including the crude mortality rate (CMR), age-standardized mortality rate worldwide (ASMRW), years of life lost (YLL), and age-specific proportions. We also examined the impact of population aging on the burden of CHD. The Joinpoint Regression Program was used to analyze trends, and the decomposition method was used to evaluate the impact of demographics on the mortality rate.

RESULTS

Of the 86,171 CHD-related deaths, 52,152 (60.52%) were CHD-specific deaths. For both CHD-related and CHD-specific deaths, there was a significant increase in the CMR, ASMRW, and YLL rate, except in the 70-79-year age group, which exhibited a distinctive and statistically significant decline in these rates (all P < 0.05). There were steadily increasing trends in the rates caused by aging from 2005 to 2020, with average annual percent changes (AAPCs) of 42.59% and 41.43%, respectively (all P < 0.05).

CONCLUSIONS

Our results indicate that the CHD burden in Pudong has been persistently increasing, but in the age group of 70-79 years, substantial declines were observed. The quality of primary healthcare services may be a critical point in addressing the overwhelming CHD burden.

Acute Health Care Provision in Rural Long-Term Care Facilities: A Scoping Review of Integrated Care Models

OBJECTIVES

We aimed to map integrated care models for acute health care in rural long-term care facilities (LTCFs) for future investigation.

DESIGN

Systematic scoping review.

SETTING AND PARTICIPANTS

Residential LTCFs in rural areas worldwide.

METHODS

The common health-related online databases were systematically searched complemented by a manual search of gray literature. Following the 5-stage framework of Arksey and O'Malley, the extent of included literature was identified and findings were summarized using qualitative meta-summary.

RESULTS

A total of 35 references were included for synthesis, predominantly primary research on completed and ongoing projects reporting on integrated health care services in rural LTCFs. Incorporating previous research, we extracted 5 approaches of integrated acute-health care models: (1) Availability of Specialists, (2) Networks, (3) Quality Management (QM) and Organization, (4) Telemedicine, and (5) Telehealth.

CONCLUSIONS AND IMPLICATIONS

This research presents the result of a literature review examining integrated care models as a way to improve acute health care in LTCFs in rural areas. Integrated care models in rural settings can help face the challenging situation and fulfil the complex health care needs of LTCF residents by reducing fragmentation and thereby improve continuity and coordination of acute health care services. These results can guide policy making in creating interventions and support adequate implementation of care models by knowledge translation in health care.

Contamination of herbal medicinal products in low-and-middle-income countries: A systematic review

The use of herbal medicinal products (HMPs) has grown significantly across low-and-middle-income countries (LMICs). Consequently, the safety of these products due to contamination is a significant public health concern. This systematic review aimed to determine the prevalence, types, and levels of contaminants in HMPs from LMICs. A search was performed in seven online databases, i.e., Africa journal online (AJOL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Directory of Open Access Journals (DOAJ), Health Inter-Network Access to Research Initiative (HINARI), World Health Organization Global Index Medicus (WHO GIM), Scopus, and PubMed using appropriate search queries and reported as per the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) guidelines. Ninety-one peer-reviewed articles published from 1982 to 2021 from 28 different countries across four continents were included in the study. Although metals, microbial, mycotoxins, pesticides, and residual solvents were the reported contaminants in the 91 articles, metals (56.0%, 51/91), microbial (27.5%, 25/91), and mycotoxins (18.7%, 17/91) were the most predominant. About 16.4% (1236/7518) of the samples had their contaminant levels above the regulatory limits. Samples tested for microbial contaminants had the highest proportion (46.4%, 482/1039) of contaminants exceeding the regulatory limit, followed by mycotoxins (25.8%, 109/423) and metals (14.3%, 591/4128). The proportion of samples that had their average non-essential metal contaminant levels above the regulatory limit was (57.6%, 377/655), 18.3% (88/480), 10.7% (24/225), and 11.3% (29/257) for Pb, Cd, Hg, and As, respectively. The commonest bacteria species found were Escherichia coli (52.3%, 10/19) and Salmonella species (42.1%, 8/19). This review reported that almost 90% of Candida albicans and more than 80% of moulds exceeded the required regulatory limits. HMP consumption poses profound health implications to consumers and patients. Therefore, designing and/or implementing policies that effectively regulate HMPs to minimize the health hazards related to their consumption while improving the quality of life of persons living in LMICs are urgently needed.

Primary healthcare delivery models in African conflict-affected settings: a systematic review

BACKGROUND

In conflict-affected settings, access to primary healthcare for displaced populations is constrained by multiple challenges. These include geographical, cultural, communication, logistical and financial barriers, as well as risks posed to health workers and the population by insecurity. Different models of care are used to provide primary healthcare to affected communities. However, there is a paucity of evidence on how these models are selected and implemented by organisations working in conflict and displacement-affected settings. Our aim was to explore the different primary healthcare delivery models used in conflict-affected settings to understand gaps in existing healthcare delivery models.

METHODS

We conducted a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The review protocol was registered with the International Prospective Register of Systematic Reviews. We searched six databases for manuscripts published from January 1992 to December 2020. Publications were included if they reported primary healthcare models of care in conflict-affected settings of Africa. Data was analyzed descriptively and thematically using tables, charts and text.

RESULTS

Forty-eight primary research articles were included for analysis from which thirty-three were rated as "high" quality. The results showed that the models of care in place in these conflict-affected settings include health facility-based, community-based, mobile clinics, outreach and home visits. Primary healthcare for internally displaced persons and refugees is provided by a wide range of actors including national and international organisations. A range of services is offered, most commonly nutrition, mental health and sexual/reproductive health. Some organisations offer vertical (stand-alone) services, while others use an integrated service delivery model. Multiple cadres of healthcare workers provide services, frequently lay healthcare workers such as Community Health Workers.

CONCLUSION

Understanding the different modalities of primary healthcare delivery in conflict-affected settings is important to identify existing practices and gaps in service delivery. Service delivery using community health workers in conflict-affected settings is a low-cost primary care delivery strategy that may help optimize contributions of existing personnel through task shifting.

Implementing community-based health program in conflict settings: documenting experiences from the Central African Republic and South Sudan

BACKGROUND

The delivery of quality healthcare for women and children in conflict-affected settings remains a challenge that cannot be mitigated unless global health policymakers and implementers find an effective modality in these contexts. The International Committee of the Red Cross (ICRC) and the Canadian Red Cross (CRC) used an integrated public health approach to pilot a program for delivering community-based health services in the Central African Republic (CAR) and South Sudan in partnership with National Red Cross Societies in both countries. This study explored the feasibility, barriers, and strategies for context-specific agile programming in armed conflict affected settings.

METHODS

A qualitative study design with key informant interviews and focus group discussions using purposive sampling was used for this study. Focus groups with community health workers/volunteers, community elders, men, women, and adolescents in the community and key informant interviews with program implementers were conducted in CAR and South Sudan. Data were analyzed by two independent researchers using a content analysis approach.

RESULTS

In total, 15 focus groups and 16 key informant interviews were conducted, and a total of 169 people participated in the study. The feasibility of service delivery in armed conflict settings depends on well-defined and clear messaging, community inclusiveness and a localized plan for delivery of services. Security and knowledge gaps, including language barriers and gaps in literacy negatively impacted service delivery. Empowering women and adolescents and providing context-specific resources can mitigate some barriers. Community engagement, collaboration and negotiating safe passage, comprehensive delivery of services and continued training were key strategies identified for agile programming in conflict settings.

CONCLUSION

Using an integrative community-based approach to health service delivery in CAR and South Sudan is feasible for humanitarian organizations operating in conflict-affected areas. For agile, and responsive implementation of health services in conflict-affected settings, decision-makers should focus on effectively engaging communities, bridge inequities through the engagement of vulnerable groups, collaborate and negotiate for safe passage for delivery of services, keep logistical and resource constraints in consideration and contextualize service delivery with the support of local actors.

Retracing loss of momentum for primary health care: can renewed political interest in the context of COVID-19 be a turning point?

The COVID-19 pandemic has revealed major weaknesses in primary health care (PHC), and how such weaknesses pose a catastrophic threat to humanity. As a result, strengthening PHC has re-emerged as a global health priority and will take centre stage at the 2023 United Nations High Level Meeting (UNHLM) on Universal Health Coverage (UHC). In this analysis, we examine why, despite its fundamental importance and incredible promise, the momentum for PHC has been lost over the years. The portrayal of PHC itself (policy image) and the dominance of global interests has undermined the attractiveness of intended PHC reforms, leading to legacy historical policy choices (critical junctures) that have become extremely difficult to dismantle, even when it is clear that such choices were a mistake. PHC has been a subject of several political declarations, but post-declarative action has been weak. The COVID-19 provides a momentous opportunity under which the image of PHC has been reconstructed in the context of health security, breaking away from the dominant social justice paradigms. However, we posit that effective PHC investments are those that are done under calm conditions, particularly through political choices that prioritise the needs of the poor who continue to face a crisis even in non-pandemic situations. In the aftermath of the 2023 UNHLM on UHC, country commitment should be evaluated based on the technical and financial resources allocated to PHC and tangible deliverables as opposed to the formulation of documents or convening of a gathering that simply (re) endorses the concept.

Effects of primary healthcare reform on routine health information systems (RHISs): a mixed-methods study in Lesotho

BACKGROUND AND OBJECTIVE

The Ministry of Health of Lesotho and Partners In Health piloted the Lesotho National Primary Health Care Reform (LPHCR) from July 2014 to June 2017 to improve quality and quantity of service delivery and enhance health system management. This initiative included improvement of routine health information systems (RHISs) to map disease burden and reinforce data utilisation for clinical quality improvement.

METHODS AND ANALYSIS

The WHO Data Quality Assurance framework's core indicators were used to compare the completeness of health data before versus after the LPHCR in 60 health centres and 6 hospitals across four districts. To examine change in data completeness, we conducted an interrupted time series analysis using multivariable logistic mixed-effects regression. Additionally, we conducted 25 key informant interviews with healthcare workers (HCWs) at the different levels of Lesotho's health system, following a purposive sampling approach. Interviews were analysed using deductive coding based on the Performance of Routine Information System Management framework, which inspected organisational, technical and behavioural factors influencing RHIS processes and outputs associated with the LPHCR.

RESULTS

In multivariable analyses, trends in monthly data completion rate were higher after versus before the LPHCR for: documenting first antenatal care visit (adjusted OR (AOR): 1.24, 95% CI: 1.14 to 1.36) and institutional delivery (AOR: 1.19, 95% CI: 1.07 to 1.32). When discussing processes, HCWs highlighted the value of establishing clear roles and responsibilities in reporting under a new organisational structure, improved community programmes among district health management teams, and enhanced data sharing and monitoring by districts.

CONCLUSION

The Ministry of Health had a strong data completion rate pre-LPHCR, which was sustained throughout the LPHCR despite increased service utilisation. The data completion rate was optimised through improved behavioural, technical and organisational factors introduced as part of the LPHCR.

Implementation considerations for non-communicable disease-related integration in primary health care: a rapid review of qualitative evidence

BACKGROUND

Integrated delivery of primary health care (PHC) services is a health reform recommended for achieving ambitious targets of the Sustainable Development Goals and Universal Health Coverage, responding to growing challenges of managing non-communicable and multimorbidity. However, more evidence is needed on effective implementation of PHC integration in different country settings.

OBJECTIVE

This rapid review synthesized qualitative evidence on implementation factors affecting integration of non-communicable disease (NCD) into PHC, from the perspective of implementers. The review contributes evidence to inform the World Health Organizations' guidance on integration of NCD control and prevention to strengthen health systems.

METHOD

The review was guided by standard methods for conducting rapid systematic reviews. Data analysis was guided by the SURE and WHO health system building blocks frameworks. We used Confidence in the Evidence of Reviews of Qualitative Research (GRADE-CERQual) to assess the confidence of the main findings.

RESULTS

The review identified 81 records eligible for inclusion, from 595 records screened. We sampled 20 studies for analysis (including 3 from expert recommendations). Studies covered a wide range of countries (27 countries from 6 continents), the majority from low-and middle-income countries (LMICs), with a diverse set of NCD-related PHC integration combinations and implementation strategies. The main findings were categorised into three overarching themes and several sub-themes. These are, A: Policy alignment and governance, B: Health systems readiness, intervention compatibility and leadership, and C: Human resource management, development, and support. The three overarching findings were assessed as each having a moderate level of confidence.

CONCLUSION

The review findings present insights on how health workers responses may be shaped by the complex interaction of individual, social, and organizational factors that may be specific to the context of the intervention, the importance of cross-cutting influences such as policy alignment, supportive leadership and health systems constraints, knowledge that can inform the development of future implementation strategies and implementation research.

Bibliometric Analysis of Research Themes and Trends of the Co-Occurrence of Autism and ADHD

Background

In recent years, there has been a growing body of research suggesting that ASD and ADHD are two disorders that often co-exist. Despite the rapid development of research, little is known about their etiology, diagnostic markers, and interventions, which has led us to review and summarise the development of the field in the hope that this will provide an opportunity to look for future directions.

Methods

A bibliometric approach was used to analyse papers in the field of ASD co-morbidities in ADHD on Web of Science from 1991-2022, using CiteSpace and VOSview to map the country/institution, journal, author, co-citation, and keyword networks in the field and to visualise the results.

Results

A total of 3284 papers were included, showing an increasing trend in terms of posting trends. Research on co-morbidities of ASD has proven to be mainly focused on universities. The USA (1662) published the most relevant literature in this area, followed by the UK (651) and Sweden (388). Lichtenstein P is the most published author (84), and research into the pathogenesis of ASD co-occurring ADHD and related clinical diagnostics is currently at the forefront of the field.

Conclusion

This analysis identifies the most influential institutions and countries, cited journals, and authors in the field of ASD co-morbid ADHD research. The future direction of ASD co-occurring ADHD should be based on improving case identification, discovering the etiological and diagnostic markers of ASD and ADHD, and finding more effective clinical interventions.

Screening and Interventions for Cardiovascular Disease Prevention in the Limpopo Province, South Africa: Use of the Community Action Model

The rise in non-communicable diseases (NCDs) has been attributed to economic growth in developing countries, shifts in societal norms, and behaviors such as dietary habits and physical activity. Up to 80% of NCDs could be prevented by eliminating shared risk factors, mainly tobacco use, unhealthy diets, physical inactivity, and the harmful use of alcohol. The South African government’s national strategic plan to control NCDs, which includes cardiovascular disease (CVD) prevention, places a strong emphasis on the need to improve the prevention, detection, early intervention, and management of NCDs. In line with the above recommendations, this study aimed to screen rural communities using the non-laboratory INTERHEART Risk Score tool (NLIRS) and develop relevant and suitable intervention strategies for a patient at moderate risk of developing a heart attack. A quantitative research approach applying a household-based design was used to conduct this study and the community action model (CAM). The difference between pre-intervention and post-intervention results were analyzed using a t-test and Analysis of covariance (ANCOVA) with age, smoke, hypertension, and diabetes as the covariates. The study found a significant difference in proportions between pre and post-intervention for raised Systole (SBP), obesity by body mass index (BMI), and waist circumference (WC). In rural communities, using CAM to improve knowledge and behavioral practices of NCD risk factors is feasible and effective. This basket of interventions will assist community members in reducing their risk of developing metabolic syndromes as well as their risk of developing CVDs. Continued investment and research in CVD prevention interventions are required to improve health, reduce costs, and have long-term benefits for conflict-affected individuals and communities.

Chronic disease care integration into primary care services in sub-Saharan Africa: a 'best fit' framework synthesis and new conceptual model

OBJECTIVE

To examine the relevance of existing chronic care models to the integration of chronic disease care into primary care services in sub-Saharan Africa and determine whether additional context-specific model elements should be considered.

DESIGN

'Best fit' framework synthesis comprising two systematic reviews. First systematic review of existing chronic care conceptual models with construction of a priori framework. Second systematic review of literature on integrated HIV and diabetes care at a primary care level in sub-Saharan Africa, with thematic analysis carried out against the a priori framework. New conceptual model constructed from a priori themes and new themes. Risk of bias of included studies was assessed using CASP and MMAT.

ELIGIBILITY CRITERIA

Conceptual models eligible for inclusion in construction of a priori framework if developed for a primary care context and described a framework for long-term management of chronic disease care. Articles eligible for inclusion in second systematic review described implementation and evaluation of an intervention or programme to integrate HIV and diabetes care into primary care services in SSA.

INFORMATION SOURCES

PubMed, Embase, CINAHL Plus, Global Health and Global Index Medicus databases searched in April 2020 and September 2022.

RESULTS

Two conceptual models of chronic disease care, comprising six themes, were used to develop the a priori framework. The systematic review of primary research identified 16 articles, within which all 6 of the a priori framework themes, along with 5 new themes: Improving patient access, stigma and confidentiality, patient-provider partnerships, task-shifting, and clinical mentoring. A new conceptual model was constructed from the a priori and new themes.

CONCLUSION

The a priori framework themes confirm a need for co-ordinated, longitudinal chronic disease care integration into primary care services in sub-Saharan Africa. Analysis of the primary research suggests integrated care for HIV and diabetes at a primary care level is feasible and new themes identified a need for a contextualised chronic disease care model for sub-Saharan Africa.

Indicator-activities to apply primary health care principles in national or large-scale community health worker programs in low-and middle-income countries: a Delphi exercise

INTRODUCTION

Primary Health Care (PHC) gained considerable momentum in the past four decades and led to improved health outcomes across a wide variety of settings. In low-and middle-income countries (LMICs), national or large-scale Community Health Worker Programs (CHWPs) are considered as vehicles to incorporate PHC principles into healthcare provision and are an essential aspect of the PHC approach to achieve health for all and sustainable development goals. The success of CHWPs is rooted in the application of PHC principles. However, there is evidence that shows patchy implementation of PHC principles across national CHWPs in LMICs. This may reflect the lack of information on what activities would illustrate the application of these principles in CHWPs. This study aimed to identify a set of core/indicator-activities that reflect the application of PHC principles by CHWPs in LMICs.

METHODS

A two-round modified Delphi study was undertaken with participants who have extensive experience in planning, implementation and evaluation of CHWPs. Survey design and analysis was guided by the four PHC principles namely Universal Health Coverage, Community Participation, Intersectoral Coordination and Appropriateness. Responses were collected using a secure online survey program (survey monkey). In round one, participants were asked to list 'core activities' that would reflect the application of each PHC principle and its sub-attributes and challenges to apply these principles in CHWPs. In round two, participants were asked to select whether they agree or disagree with each of the activities and challenges. Consensus was set a priori at 70% agreement of participants for each question.

RESULTS

Seventeen participants from 15 countries participated in the study. Consensus was reached on 59 activities reflecting the application of PHC principles by CHWPs. Based on participants' responses, a set of 29 indicator-activities for the four PHC principles was developed with examples for each indicator-activity.

CONCLUSION

These indicator-activities may provide guidance on how PHC principles can be implemented in CHWPs. They can be used in the development and evaluation of CHWPs, particularly in their application of PHC principles. Future research may focus on testing the utility of indicator-activities on CHWPs in LMICs.

Title: the impact of a pilot integrated care model on the quality and costs of inpatient care among chinese elderly: a difference-in-difference analysis of repeated cross-sectional data

Background

Recently, integrated care has received tremendous popularity in China, a leading example of which is the Luohu model. In the present analysis, we aimed to examine the impacts of the Luohu model on the quality and costs of inpatient care.

Methods

We conducted a retrospective analysis using administrative claims databases of Shenzhen City (the city that the Luohu district sits) from Jan 2015–Apr 2017, which encompassed the time before and after the implementation of the pilot model. The outcomes were 30-day readmission, inpatient costs, and length of stay (LOS). Multivariable difference-in-difference analyses were conducted.

Results

In the first year following the integration, the Luohu model did not have impacts on any of the outcomes. Although its effect on readmission (ratio of odds ratio: 1.082; 95% CI: 0.865 to 1.353) was still not identified in the first four months of the second post-integration year, it decreased inpatient costs by CN¥ 1224.1 (95% CI: 372.7 to 2075.5) and LOS by 0.938 days (95% CI: 0.0416 to 1.835) per hospitalization episode during the same period.

Conclusions

The Luohu model may reduce costs and LOS in the long term. It is potentially a viable approach to improve the value of inpatient care in China.

Intersectoral and multisectoral approaches to health policy: an umbrella review protocol

BACKGROUND

It is widely recognized that one's health is influenced by a multitude of nonmedical factors, known as the social determinants of health (SDH). The SDH are defined as "the conditions in which people are born, grow, live, work and age, and which are shaped by the distribution of money, power and resources at global, national and local levels". Despite their influence on health, most of the SDH are targeted through government departments and ministries outside of the traditional health sector (e.g. education, housing). As such, the need for intersectoral and multisectoral approaches arises. Intersectoral and multisectoral approaches are thought to be essential to addressing many global health challenges our world faces today and achieving the Sustainable Development Goals. There are various ways of undertaking intersectoral and multisectoral action, but there are three widely recognized approaches (Health in All Policies [HiAP], Healthy Cities, and One Health) that each have a unique focus. However, despite the widespread acceptance of the need for intersectoral and multisectoral approaches, knowledge around how to support, achieve and sustain multisectoral action is limited. The goal of this study is to assemble evidence from systematic approaches to reviewing the literature (e.g. scoping review, systematic review) that collate findings on facilitators/enablers and barriers to implementing various intersectoral and multisectoral approaches to health, to strengthen understanding of how to best implement health policies that work across sectors, whichever they may be.

METHODS

An umbrella review (i.e. review of reviews) is to be undertaken to collate findings from the peer-reviewed literature, specifically from Ovid MEDLINE and Scopus databases. This umbrella review protocol was developed following the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P), and study design informed by the PRISMA guidelines for scoping reviews (PRISMA-ScR).

DISCUSSION

Countries that employ multisectoral approaches are better able to identify and address issues around poverty, housing and others, by working collaboratively across sectors, with multisectoral action by governments thought to be required to achieve health equity.

Exploring facilitators and barriers to introducing health technology assessment: a systematic review

Objective

This study aims to identify and codify the facilitators and barriers to help implementing partners institutionalize health technology assessment (HTA) successfully and navigate complex systems for health-related policy making.

Methods

We searched for peer-reviewed and gray literature articles examining HTA programs globally using six databases. Keywords used as a guide for capturing articles included “health technology assessment,” “barrier,” and “facilitator” and their synonyms. Search results were scrutinized for duplicates and screened through a review of titles and abstracts. A full-text review was conducted exploring articles’ coverage of twenty-seven evaluation criteria across four primary areas of interest: barriers/facilitators, motivations, guidelines, and institutional frameworks.

Results

A total of 18,599 records were identified for duplication check, title, and abstract review. A total of 1,594 articles underwent full-text review, leading to a final synthesis of 262 studies. We found that ninety-seven articles discussed barriers/facilitators, with fifty-three of those discussing local capacity and unavailable human resources. Out of the sixty-six articles discussing motivations, forty-two cited the interest in supporting the decision-making process for, and promoting, appropriate resource allocation. Of the sixty-one articles that discussed guidelines and institutional framework, twenty-one articles described HTA as an independent national unit, and sixteen described their HTA unit as a unit within the Ministry of Health (MOH).

Conclusions

This systematic review unpacks the dynamic and relevant contexts for understanding the HTA institutionalization process to help policy makers and practitioners achieve tangible progress in confronting the most critical issues facing priority setting and HTA institutionalization.

The role of registered charities in the delivery of global surgery in low- and middle-income countries - a personal experience

The world's resources are unequally divided. Investment in healthcare in Low- and Middle-Income Countries (LMICs) has traditionally involved vertical public health strategies with little emphasis on the delivery of safe and effective surgery and anesthesia. The past 20 years has witnessed greater awareness of the numbers of people who have no access to surgery, the morbidity and mortality of such limited access, and the cost to the individual and society if a solution is not found. Global surgery has become a hot topic and The Millennium Development Goals (MDG) and the Sustainable Development Goals (SDG) have underlined the importance of surgery in national health care plans. The harsh metrics reported by the Lancet Commission has framed the problem in more concrete terms and as of today, over 5 billion people lack access to safe surgery, over 143 million extra surgeries are needed annually to affect the imbalance and more than 15,000 children die each day in Sub Saharan Africa and Southeast Asia from preventable disease, including the lack of access to safe surgery. Horizontal integrated healthcare that includes surgical provision is the new norm, but its introduction is expensive and will need time. The ambition of universal healthcare access for all people (SDG) with a corresponding reduction in child and maternal mortality will be difficult for most governments. Altruistic, Non-Governmental Organizations (NGOs) are ideally placed to assist this goal but must introduce changes in practice to include onsite and off-site training, broad partnerships with other NGOs and academic bodies and greater advocacy with governments to ensure sustainability. NGOs should work in concert with local agencies, hospitals and governments to meet local needs.

Experiences of nursing students regarding clinical placement and support in primary healthcare clinics: Strengthening resilience

Background

This research addressed the need to have a deeper understanding of nursing students’ experiences of clinical placement and support in primary healthcare (PHC) settings.

Aim

To explore and describe the experiences of nursing students’ clinical placement in PHC settings.

Setting

The study was conducted at PHC clinics in a specific province in South Africa.

Method

A qualitative, exploratory, descriptive and contextual research design was used. The population comprised fourth-year nursing students selected using purposive sampling. Five semi-structured focus group interviews were conducted. Data saturation determined the sample size which comprised 25 nursing students. Thematic data analysis produced four main themes.

Results

The main themes were (1) the meaning of placement, (2) experiences of clinical placement, (3) needs for support, and (4) resilience of nursing students.

Conclusions

Nursing students encountered negative and positive experiences. Both experiences confirmed that PHC settings can be valuable learning opportunities for nursing students. Nursing students appreciated the supervision of professional nurses who created an atmosphere conducive for teaching and learning by welcoming and encouraging nursing students’ independence. Recommendations include: appointing a professional nurse specifically for supervision of nursing students, tutor support before summative examinations, improvement of services, including the availability of resources.

Contribution

This article contributes to awareness of how nursing students manage to stay resilient irrespective of negative experiences during clinical placement and how tutors and professional nurses can support them. The study’s recommendations can guide professional nurses, nurse educators, nurse managers and other healthcare PHC workers to support nursing students.

Tele-Neurorehabilitation During the COVID-19 Pandemic: Implications for Practice in Low- and Middle-Income Countries

The importance of neurorehabilitation services for people with disabilities is getting well-recognized in low- and middle-income countries (LMICs) recently. However, accessibility to the same has remained the most significant challenge, in these contexts. This is especially because of the non-availability of trained specialists and the availability of neurorehabilitation centers only in urban cities owned predominantly by private healthcare organizations. In the current COVID-19 pandemic, the members of the Task Force for research at the Indian Federation of Neurorehabilitation (IFNR) reviewed the context for tele-neurorehabilitation (TNR) and have provided the contemporary implications for practicing TNR during COVID-19 for people with neurological disabilities (PWNDs) in LMICs. Neurorehabilitation is a science that is driven by rigorous research-based evidence. The current pandemic implies the need for systematically developed TNR interventions that is evaluated for its feasibility and acceptability and that is informed by available evidence from LMICs. Given the lack of organized systems in place for the provision of neurorehabilitation services in general, there needs to be sufficient budgetary allocations and a sector-wide approach to developing policies and systems for the provision of TNR services for PWNDs. The pandemic situation provides an opportunity to optimize the technological innovations in health and scale up these innovations to meet the growing burden of neurological disability in LMICs. Thus, this immense opportunity must be tapped to build capacity for safe and effective TNR services provision for PWNDs in these settings.

Association between diabetes and edentulism and their joint effects on health status in 40 low and middle-income countries

INTRODUCTION

Previous studies on the diabetes-edentulism relationship have yielded conflicting results. Therefore, the goal of this study was to investigate the association between diabetes and edentulism, and their joint effects on health status in adults from 40 low and middle-income countries (LMICs).

RESEARCH DESIGN AND METHODS

Data from the World Health Survey were used for this cross-sectional study (2002-2004). Forty countries (18 low-income and 22 middle-income countries) were included. Edentulism and diabetes were assessed using yes-no questions based on self-report. Health status was assessed in seven different domains (self-care, pain/discomfort, cognition, interpersonal activities, sleep/energy, affect, and perceived stress). The association between diabetes (exposure) and edentulism (outcome) was analyzed using multivariable logistic regression models, while their joint effects on health status were assessed using multivariable linear regression models.

RESULTS

There were 175 814 adults aged ≥18 years included in this study (mean (SD) age 38.4 (16.0) years; 49.3% men). Overall, the prevalence of edentulism was 6.0% and diabetes was 2.9%. There was a positive and significant association between diabetes and edentulism in the overall sample (OR=1.40, 95% CI 1.18 to 1.66), in low-income countries (OR=1.78, 95% CI 1.21 to 2.62) and in middle-income countries (OR=1.24, 95% CI 1.04 to 1.47). In addition, people with comorbid diabetes and edentulism had worse health status in the domains of cognition, sleep/energy, and perceived stress, compared with those with diabetes only.

CONCLUSIONS

Diabetes was positively associated with edentulism in this sample of more than 175 000 individuals living in LMICs. Providing oral care to individuals with diabetes may potentially lead to a reduction in their risk of edentulism.

Forms of Health System Fragmentation During Conflict: The Case of Yemen

The continuous and protracted conflict in Yemen has evolved into the worst humanitarian situation in modern history. All public structures in the country, including the health system and its basic functions, have been under tremendous pressures. One of the key obstacles to improve the health outcomes in Yemen is fragmentation of the health system. This study aims at exploring and documenting the forms of health system fragmentation in humanitarian and conflict-affected contexts by studying Yemen as a case study. We collected national qualitative data from key informants through in-depth interviews. A pool of respondents was identified from the Ministry of Public Health and Population, donors, and non-governmental organizations. Data were collected between May and June 2019. We interviewed eight key informants and reviewed national health policy documents, and references provided by key informants. Interviews were recorded, transcribed, and analyzed using qualitative content analysis. We further conducted a literature review to augment and triangulate the findings. Six themes emerged from our datasets and analyses, representing various forms of fragmentation: political, structural, inter-sectoral, financial, governance, and health agenda-related forms. Health system fragmentation in Yemen existed before the conflict eruption and has aggravated as the conflict evolves. The humanitarian situation and the collapsing health system enabled the influx of various national and international health actors. In conclusion, the protracted conflict and fragile situation in Yemen have accentuated the fragmentation of the health system. Addressing these fragmentations' forms by all health actors and building consensus on health system agenda are recommended. Health system analysis and in-depth study of fragmentation drivers in Yemen can be beneficial to build common ground and priorities to reduce health system fragmentation. Furthermore, capacity building of a health system is fundamental for the humanitarian development nexus, health system integration, and recovery efforts in the future.

The Rising Burden of Diabetes-Related Blindness: A Case for Integration of Primary Eye Care into Primary Health Care in Eswatini

There is a rampant increase in diabetes prevalence globally. Sub-Saharan Africa (SSA) is projected to carry the largest burden of diabetes (34.2 million) by 2030. This will inevitably cause a parallel increase in diabetes-associated complications; with the predominant complications being blindness due to diabetic retinopathy and diabetic cataracts. Eye programs in developing countries remain inadequate, existing as stand-alone programs, focused on the provision of acute symptomatic care at secondary and tertiary health levels. Over 60% of people with undiagnosed diabetes report to eye care facilities with already advanced retinopathy. While vision loss due to cataracts is reversible, loss of vision from diabetic retinopathy is irreversible. Developing countries have in the last two decades been significantly impacted by infectious pandemics; with SSA countries committing over 80% of their health budgets towards infectious diseases. Consequently, non-communicable diseases and eye health have been neglected. This paper aimed to highlight the importance of strengthening primary health care services to prevent diabetes-related blindness. In SSA, where economies are strained by infectious disease, the projected rise in diabetes prevalence calls for an urgent need to reorganize health systems to focus on life-long preventative and integrated measures. However, research is critical in determining how best to integrate these without further weakening health systems.

The Role of Noncommunicable Diseases in the Pursuit of Global Health Security

Noncommunicable diseases and their risk factors are important for all aspects of outbreak preparedness and response, affecting a range of factors including host susceptibility, pathogen virulence, and health system capacity. This conceptual analysis has 2 objectives. First, we use the Haddon matrix paradigm to formulate a framework for assessing the relevance of noncommunicable diseases to health security efforts throughout all phases of the disaster life cycle: before, during, and after an event. Second, we build upon this framework to identify 6 technical action areas in global health security programs that are opportune integration points for global health security and noncommunicable disease objectives: surveillance, workforce development, laboratory systems, immunization, risk communication, and sustainable financing. We discuss approaches to integration with the goal of maximizing the reach of global health security where infectious disease threats and chronic disease burdens overlap.

Evidence of integrated health service delivery during COVID-19 in low and lower-middle-income countries: protocol for a scoping review

INTRODUCTION

The importance of integrated, people-centred health systems has been recognised as a central component of Universal Health Coverage. Integration has also been highlighted as a critical element for building resilient health systems that can withstand the shock of health emergencies. However, there is a dearth of research and systematic synthesis of evidence on the synergistic relationship between integrated health services and pandemic preparedness, response, and recovery in low-income and lower-middle-income countries (LMICs). Thus, the authors are organising a scoping review aiming to explore the application of integrated health service delivery approaches during the emerging COVID-19 pandemic in LMICs.

METHODS AND ANALYSIS

This scoping review adheres to the six steps for scoping reviews from Arksey and O'Malley. Peer-reviewed scientific literature will be systematically assembled using a standardised and replicable search strategy from seven electronic databases, including PubMed, Embase, Scopus, Web of Science, CINAHL Plus, the WHO's Global Research Database on COVID-19 and LitCovid. Initially, the title and abstract of the collected literature, published in English from December 2019 to June 2020, will be screened for inclusion which will be followed by a full-text review by two independent reviewers. Data will be charted using a data extraction form and reported in narrative format with accompanying data matrix.

ETHICS AND DISSEMINATION

No ethical approval is required for the review. The study will be conducted from June 2020 to May 2021. Results from this scoping review will provide a snapshot of the evidence currently being generated related to integrated health service delivery in response to the COVID-19 pandemic in LMICs. The findings will be developed into reports and a peer-reviewed article and will assist policy-makers in making pragmatic and evidence-based decisions for current and future pandemic responses.

The Implications of Zinc Therapy in Combating the COVID-19 Global Pandemic

The global pandemic from COVID-19 infection has generated significant public health concerns, both health-wise and economically. There is no specific pharmacological antiviral therapeutic option to date available for COVID-19 management. Also, there is an urgent need to discover effective medicines, prevention, and control methods because of the harsh death toll from this novel coronavirus infection. Acute respiratory tract infections, significantly lower respiratory tract infections, and pneumonia are the primary cause of millions of deaths worldwide. The role of micronutrients, including trace elements, boosted the human immune system and was well established. Several vitamins such as vitamin A, B6, B12, C, D, E, and folate; microelement including zinc, iron, selenium, magnesium, and copper; omega-3 fatty acids as eicosapentaenoic acid and docosahexaenoic acid plays essential physiological roles in promoting the immune system. Furthermore, zinc is an indispensable microelement essential for a thorough enzymatic physiological process. It also helps regulate gene-transcription such as DNA replication, RNA transcription, cell division, and cell activation in the human biological system. Subsequently, zinc, together with natural scavenger cells and neutrophils, are also involved in developing cells responsible for regulating nonspecific immunity. The modern food habit often promotes zinc deficiency; as such, quite a few COVID-19 patients presented to hospitals were frequently diagnosed as zinc deficient. Earlier studies documented that zinc deficiency predisposes patients to a viral infection such as herpes simplex, common cold, hepatitis C, severe acute respiratory syndrome coronavirus (SARS-CoV-1), the human immunodeficiency virus (HIV) because of reducing antiviral immunity. This manuscript aimed to discuss the various roles played by zinc in the management of COVID-19 infection.

Evidence for the Use of Triage, Respiratory Isolation, and Effective Treatment to Reduce the Transmission of Mycobacterium Tuberculosis in Healthcare Settings: A Systematic Review

Evidence is limited for infection prevention and control (IPC) measures reducing Mycobacterium tuberculosis (MTB) transmission in health facilities. This systematic review, 1 of 7 commissioned by the World Health Organization to inform the 2019 update of global tuberculosis (TB) IPC guidelines, asked: do triage and/or isolation and/or effective treatment of TB disease reduce MTB transmission in healthcare settings? Of 25 included articles, 19 reported latent TB infection (LTBI) incidence in healthcare workers (HCWs; absolute risk reductions 1%-21%); 5 reported TB disease incidence in HCWs (no/slight [high TB burden] or moderate [low burden] reduction) and 2 in human immunodeficiency virus-positive in-patients (6%-29% reduction). In total, 23/25 studies implemented multiple IPC measures; effects of individual measures could not be disaggregated. Packages of IPC measures appeared to reduce MTB transmission, but evidence for effectiveness of triage, isolation, or effective treatment, alone or in combination, was indirect and low quality. Harmonizing study designs and reporting frameworks will permit formal data syntheses and facilitate policy making.

The Greatest Challenge to Using AI/ML for Primary Health Care: Mindset or Datasets?

The global vision for primary health care (PHC) is defined by regular access to quality care for comprehensive services throughout the course of life. However, this is not what typically happens, especially in low- and middle-income countries, where many people access the formal health system only for emergent needs. Yet, even episodic care is nearly impossible to attain due to infrastructure barriers, critical shortages of health care providers, and low-quality care. Artificial intelligence and machine learning (AI/ML) can help us revolutionize the current reality of health care into the vision of continuous health care that promotes individuals to maintain a constant healthy state. AI/ML can deliver precise recommendations to the individual, transforming patients from a passive receiver of health services into an active participant of their own care. By accounting for each individual, AI/ML can also ensure equitable coverage for entire populations with an ongoing data exchange between personal health, genomic data, public health, and environmental factors. The greatest challenge to enlisting AI/ML in the quest toward the PHC vision will be instilling a sense of responsibility with global citizens to recognize health data for the global good while prioritizing protected, individually owned data sets. Only when individuals start taking a collective approach to health data, shifting the mindset toward the goal of prevention, will the potential of AI/ML for PHC be realized. Until we overcome this challenge, the paradigm shift of the global community away from our ad hoc, reactive health system culture will not be achieved.

Opportunities for gender transformative approaches in a community-based drowning reduction program in Bangladesh

Background

Community-based programs in rural low-and middle-income country settings are well-placed to conduct gender transformative activities that aid program sustainability and catalyse wider social change, such as reducing gender inequities that in turn improve health outcomes. The Anchal program is a drowning prevention intervention for children aged 1–5 years old in rural Bangladesh. It provides community crèche-based supervision delivered by local trained paid-female volunteers. We aimed to identify the influence of the Anchal program on gender norms and behaviours in the community context, and the effects these had on program delivery and men and women’s outcomes.

Methods

Qualitative in-depth interviews, focus group discussions and observations were conducted with program beneficiaries and providers. Gender outcomes were analysed using FHI 360’s Gender Integration Framework.

Results

The Anchal program was found to be a gender accommodating program as it catered for communities’ gender-based roles and constraints but did not actively seek to change underlying beliefs, perceptions and norms that led to these. The program in some cases enhanced the independence and status of female community staff. This changed perceptions of communities towards acceptable levels of physical mobility and community involvement for women. Conversely, gender affected program delivery by reducing the ability of female supervisory staff to engage with male community leaders. The double burden of wage and household labour carried by local female staff also limited performance and progression. Gender-based constraints on staff performance, attrition and community engagement affected efficiency of program delivery and sustainability.

Conclusions

The Anchal program both adapted to and shaped community gender norms and roles. The program has well-established relationships in the community and can be leveraged to implement gender transformative activities to improve gender-based equity. Health programs can broaden their impacts and target social determinants of health like gender equity to increase program sustainability and promote equitable health outcomes.

Strengthening Primary Health-Care Services to Help Prevent and Control Long-Term (Chronic) Non-Communicable Diseases in Low- and Middle-Income Countries

The prevalence of long-term (chronic) non-communicable diseases (NCDs) is increasing globally due to an ageing global population, urbanization, changes in lifestyles, and inequitable access to healthcare. Although previously more common in high- and upper-middle-income countries, lower-middle-income countries (LMICs) are more affected, with NCDs in LMICs currently accounting for 85–90% of premature deaths among 30–69 years old. NCDs have both high morbidity and mortality and high treatment costs, not only for the diseases themselves but also for their complications. Primary health care (PHC) services are a vital component in the prevention and control of long-term NCDs, particularly in LMICs, where the health infrastructure and hospital services may be under strain. Drawing from published studies, this review analyses how PHC services can be utilized and strengthened to help prevent and control long-term NCDs in LMICs. The review finds that a PHC service approach, which deals with health in a comprehensive way, including the promotion, prevention, and control of diseases, can be useful in both high and low resource settings. Further, a PHC based approach also provides opportunities for communities to better access appropriate healthcare, which ensures more significant equity, efficiency, effectiveness, safety, and timeliness, empowers service users, and helps healthcare providers to achieve better health outcomes at lower costs.

Cost-Effectiveness and Challenges of Implementing Intensive Blood Pressure Goals and Team-Based Care

PURPOSE OF REVIEW

Review the effectiveness, cost-effectiveness, and implementation challenges of intensive blood pressure (BP) control and team-based care initiatives.

RECENT FINDINGS

Intensive BP control is an effective and cost-effective intervention; yet, implementation in routine clinical practice is challenging. Several models of team-based care for hypertension management have been shown to be more effective than usual care to control BP. Additional research is needed to determine the cost-effectiveness of team-based care models relative to one another and as they relate to implementing intensive BP goals. As a focus of healthcare shifts to value (i.e., cost, effectiveness, and patient preferences), formal cost-effectiveness analyses will inform which team-based initiatives hold the highest value in different healthcare settings with different populations and needs. Several challenges, including clinical inertia, financial investment, and billing restrictions for pharmacist-delivered services, will need to be addressed in order to improve public health through intensive BP control and team-based care.

How context affects implementation of the Primary Health Care approach: an analysis of what happened to primary health centres in India

INTRODUCTION

In this paper, we elucidate challenges posed by contexts to the implementation of the Primary Health Care (PHC) approach, using the example of primary health centres (rural peripheral health units) in India. We first present a historical review of 'written' policies in India-to understand macro contextual influences on primary health centres. Then we highlight micro level issues at primary health centres using a contemporary case study.

METHODS

To elucidate macro level factors, we reviewed seminal policy documents in India and some supporting literature. To examine the micro context, we worked with empirical qualitative data from a rural district in Maharashtra-collected through 12 community focus group discussions, 12 patient interviews and 34 interviews with health system staff. We interpret these findings using a combination of top-down and bottom-up lenses of the policy process.

RESULTS

Primary health centres were originally envisaged as 'social models' of service delivery; front-line institutions that delivered integrated care close to people's homes. However, macro issues of chronic underfunding and verticalisation have resulted in health centres with poor infrastructure, that mainly deliver vertical programmes. At micro levels, service provision at primary health centres is affected by doctors' disinterest in primary care roles and an institutional context that promotes risk-averseness and disregard of outpatient care. Primary health centres do not meet community expectations in terms of services, drugs and attention provided; and hence, private practitioners are preferred. Thus, primary health centres today, despite having the structure of a primary-level care unit, no longer embody PHC ideals.

CONCLUSIONS

This paper highlights some contextual complexities of implementing PHC-considering macro (pertaining to ideologies and fiscal priorities) and micro (pertaining to everyday behaviours and practices of actors) level issues. As we recommit to Alma-Ata, we must be cautious of the ceremonial adoption of interventions, that look like PHC-but cannot deliver on its ideals.

Global Updates on Cardiovascular Disease Mortality Trends and Attribution of Traditional Risk Factors

PURPOSE OF REVIEW

The last 2-3 decades have witnessed a decline in age-standardized cardiovascular mortality rates in high-income regions, whereas this has only slightly decreased or even increased in most of the low- and middle-income countries. A systematic comparison of global CVD mortality by regions attributable to various modifiable risk factors such as diabetes, obesity, hypertension, poor diet, and physical inactivity is not available.

RECENT FINDINGS

We present a summary of time trends and heterogeneity in the distribution of global CVD mortality and the attribution of risk factors between 1990 and 2017 using the Global Burden of Disease (GBD) 2017 study. Globally, an estimated ~ 17.8 million (233.1 per 100,000) people died of CVD in 2017. The rate of CVD death was decreased in high-income countries (1990: 271.8 (95% UI (uncertainty interval), 270.9-273.5); 2017: 128.5 (95% UI, 126.4-130.7) per 100,000)) whereas it remained the same in lower- and middle-income countries (1990: 368.2 (95% UI, 335.6-383.3); 2017: 316.9 (95% UI, 307.0-325.5) per 100,000). Among the various traditional risk factors, high systolic blood pressure, unhealthy diet, high fasting plasma glucose, and high low-density lipoprotein levels were attributed to most of the CVD death and disability-adjusted life year lost. We also observed gender variations in tobacco and increased alcohol consumption. In addition to the traditional risk factors, poor air quality is associated with increased CVD burden in developing countries. Surveillance, country-specific guidelines, evidence-based policies, reinforcement of multisectoral health systems, and innovative solutions are urgently needed in resource-challenged settings to curb CVD risk factors and overall burden.
