Health system barriers to the implementation of the national action plan to combat antimicrobial resistance in Vietnam: a scoping review

BACKGROUND

Vietnam is among 11 countries in the Western Pacific region that has developed a National Action Plan for Antimicrobial Resistance (NAPCA).

METHODS

This scoping review characterises health system barriers to the implementation of the Vietnam NAPCA, with reference to the WHO Health Systems Framework.

RESULTS

Over 7 years, between 2013 and 2020, the Ministry of Health (MOH) of Vietnam has been implementing activities to achieve the six NAPCA objectives. They include revision of regulations needed for antimicrobial resistance (AMR) prevention programs; formation and operation of national management bodies; improvement of antimicrobial stewardship (AMS) in hospitals; maintenance of surveillance systems for AMR; provision of trainings on AMR and antibiotics use to doctors and pharmacists; and organization of nation-wide educational campaigns. Limited cooperation between MOH management bodies, shortages of human resource at all health system levels, a low degree of agreement between national and hospital guidelines on antibiotic use, low capability in the domestic supply of standardised drugs, and unequal training opportunities for lower-level health professionals present ongoing challenges. Actions suggested for the next period of the NAPCA include a final review of what has been achieved by the plan so far and evaluating the effectiveness of the different components of the plan. Different options on how to improve coordination across sectors in the development of a new NAPCA should be put forward.

CONCLUSIONS

The 6-year implementation of the Vietnam NAPCA has yielded valuable lessons for AMS in Vietnam, guiding the development of future national plans, with a central focus on scaling up AMS in hospitals and promoting community AMS programs to combat AMR.

Smoking behaviour, tobacco sales and tobacco advertising at 40 'Smoke Free Hospitals' in Vietnam

BACKGROUND

Tobacco remains the leading cause of preventable death globally. Vietnam's 2012 Law on Prevention and Control of Tobacco Harms establishes all healthcare facilities as smoke-free environments. We aimed to evaluate the implementation of these policies within health facilities across Vietnam.

METHODS

A cross-sectional study was undertaken at 40 central, provincial, district and commune healthcare facilities in four provinces of Vietnam. The presence of tobacco sales, smoke-free signage, evidence of recent tobacco use and smoking behaviours by patients and staff were observed over a 1-week period at multiple locations within each facility. Adherence with national regulations was reported using descriptive statistics.

RESULTS

23 out of 40 facilities (57.5%) followed the requirements of the national smoke-free policy regarding tobacco sales, advertising and signage. Smoking was observed within health facility grounds at 26 (65%) facilities during the observation period. Indirect evidence of smoking was observed at 35 (88%) facilities. Sites where smoking was permitted (n=2) were more likely to have observed smoking behaviour (relative risk (RR) 2.16, 95% CI 1.83 to 2.56). Facilities where tobacco was sold (n=7) were more likely to have smoking behaviour observed at any of their sites (RR 1.53, 95% CI 0.93 to 2.51).

CONCLUSIONS

Implementation of current smoke-free hospital regulations remains incomplete, with widespread evidence of smoking observed at three levels of the Vietnamese healthcare facilities. Further interventions are required to establish the reputation of Vietnamese healthcare facilities as smoke-free environments.

An analysis of the relationship between HIV risk self-perception with sexual behaviour and HIV status in South African older adults

Objective: To examine how older adults perceive their own risk of acquiring HIV; and how this perception correlates with their sexual behaviour and HIV status.Methods: We used cross-sectional survey data for 435 adults aged 50 years and older from South Africa. All participants completed a questionnaire on their basic socio-demographic and economic factors, self-reported health, sexual behaviour, HIV knowledge and attitudes, and self-perceived risk of HIV acquisition. In addition, anthropometrical measurements (weight, height, blood pressure, cholesterol) and HIV testing were conducted. Multinomial logistic regressions were used to determine the association between self-perceived HIV risk (categorised as "not at risk", at "low risk", at "high risk" and "didn't know") and being sexually active and testing HIV-positive, controlling for socio-demographic, behavioural and health-related factors.Results: Of the 435 respondents, 9.4% perceived themselves as at high risk of HIV infection, 18.9% as at low risk and 53.6% believed they were not at risk of HIV. Most respondent who perceived themselves as at low risk or not-at-risk at all of HIV were not sexually active. Older adults that were sexually active were more likely to consider themselves as at high risk of acquiring HIV (relative risk ratio [RRR] 2.05; 95% confidence interval (CI) 1.05-4.00; p = 0.036), as well as to test HIV positive (RRR 10.5; 95% CI 3.8-29.1; p < 0.001). Self-perceived HIV risk was significantly associated with age, sex, population group, and a greater awareness about HIV and how it is transmitted.Conclusions: Older persons who perceived themselves as at high risk of HIV were closely associated with sexual activity and testing HIV positive. Therefore, there is an urgent need for older persons, particularly those who remain sexually active, to screen and test for HIV routinely. Furthermore, there should be policy and programme interventions, such as the development of a simple risk-assessment tool for older adults to determine their risk for HIV. Older persons have been neglected in sexual health and HIV programmes. There is, therefore, a need to encourage older persons to take up appropriate HIV risk reduction and prevention behaviours.

Prevalence of, and factors associated with anaemia in children aged 1-3 years in Aceh, Indonesia: A cross-sectional study

Background: Child anaemia continues to represent a major public health challenge in lower-and-middle income countries. It has serious long-term consequences for child growth and development. In Indonesia, there was a 10% increase in the national prevalence of child anaemia between 2013 and 2018. Aim: This study aims to assess the prevalence of, and factors associated with anaemia among children aged one to three years in eight districts in Aceh Province, Indonesia. Methods: A cross-sectional study was conducted on a sample of 1148 mother-child dyads aged one to three years between November and December 2018. The sampling process involved a three-stage cluster sampling design using the probability proportionate to size methodology. Anaemia status was determined using haemoglobin level (Hb < 11.0 g/dL). Data were analysed using multivariable logistic regression to estimate adjusted odds ratios (aOR) and their 95% confidence intervals (95% CI) for associated factors. Results: The overall prevalence of anaemia was 76.1% (869/1142). 44.7% (510/1142) and 28.6% (327/1142) had moderate and mild anaemia, respectively. Child aged 12-24 months (aOR: 2.00, 95% CI: 1.26-3.17), not receiving routine immunisation (aOR: 2.62, 95% CI: 1.34-5.10), and maternal anaemia (aOR: 2.15, 95% CI: 1.59-2.90) were significantly associated with anaemia. Conclusion: The prevalence of anaemia among the children in this study was high, and was associated with child age, immunisation status, and maternal anaemia. These findings provide further insight into anaemia as a public health issue at a sub-national level in Indonesia and for development of targeted programmes to address associated risk factors of child anaemia.

Harnessing new mHealth technologies to Strengthen the Management of Multidrug-Resistant Tuberculosis in Vietnam (V-SMART trial): a protocol for a randomised controlled trial

INTRODUCTION

Multidrug-resistant tuberculosis (MDR-TB) remains a major public health problem globally. Long, complex treatment regimens coupled with frequent adverse events have resulted in poor treatment adherence and patient outcomes. Smartphone-based mobile health (mHealth) technologies offer national TB programmes an appealing platform to improve patient care and management; however, clinical trial evidence to support their use is lacking. This trial will test the hypothesis that an mHealth intervention can improve treatment success among patients with MDR-TB and is cost-effective compared with standard practice.

METHODS AND ANALYSIS

A community-based, open-label, parallel-group randomised controlled trial will be conducted among patients treated for MDR-TB in seven provinces of Vietnam. Patients commencing therapy for microbiologically confirmed rifampicin-resistant or multidrug-resistant tuberculosis within the past 30 days will be recruited to the study. Participants will be individually randomised to an intervention arm, comprising use of an mHealth application for treatment support, or a 'standard care' arm. In both arms, patients will be managed by the national TB programme according to current national treatment guidelines. The primary outcome measure of effectiveness will be the proportion of patients with treatment success (defined as treatment completion and/or bacteriological cure) after 24 months. A marginal Poisson regression model estimated via a generalised estimating equation will be used to test the effect of the intervention on treatment success. A prospective microcosting of the intervention and within-trial cost-effectiveness analysis will also be undertaken from a societal perspective. Cost-effectiveness will be presented as an incremental cost per patient successfully treated and an incremental cost per quality-adjusted life-year gained.

ETHICS

Ethical approval for the study was granted by The University of Sydney Human Research Ethics Committee (2019/676).

DISSEMINATION

Study findings will be disseminated to participants and published in peer-reviewed journals and conference proceedings.

Inappropriate supply of antibiotics for common viral infections by community pharmacies in Vietnam: A standardised patient survey

BACKGROUND

This study aimed to evaluate the appropriateness of antibiotic dispensing of private pharmacies in Vietnam.

METHODS

Standardised patient surveys were conducted in randomly selected community pharmacies across 40 districts in Vietnam. Four clinical scenarios were represented by patient actors: (a) an adult requesting treatment for a sibling with a viral upper respiratory tract infection (URTI), (b) a parent requesting treatment for a child with acute diarrhoea, (c) an adult making a direct antibiotic request, and (d) an adult presenting with an antibiotic prescription. We calculated the proportion of interactions that resulted in inappropriate supply of antibiotics and patient advice. Predictors of inappropriate antibiotic supply were assessed.

FINDINGS

Patient actors attended 949 pharmacies, resulting in 1266 clinical interactions. Antibiotics were inappropriately supplied to 92% (291/316) of adults requesting treatment for URTI symptoms, 43% (135/316) for children with acute diarrhoea symptoms and to 84% (267/317) of direct request for antibiotics. Only 49% of pharmacies advised patients regarding their antibiotic use. Female actors were more likely to be given antibiotics than male actors for URTI (aOR 2·71, 1·12-6·60) but not for diarrhoeal disease. Pharmacies in northern Vietnam were more likely than those in southern Vietnam to supply antibiotics without a prescription: for adult URTI (aOR=5·8, 95% CI: 2·2-14·9) and childhood diarrhoea (aOR=3·5, 95% CI: 2·0-6·0) symptoms, but less likely to dispense for direct antibiotics request.

INTERPRETATION

Inappropriate antibiotic supply was common in Vietnamese private pharmacies. Multifaceted measures are urgently needed to achieve WHO's global action plan for the optimal use of antimicrobials.

FUNDING

This study was funded by a grant from the Australian Department of Foreign Affairs and Trade.

How community participation in water and sanitation interventions impacts human health, WASH infrastructure and service longevity in low-income and middle-income countries: a realist review

OBJECTIVE

To understand how, and under what circumstances community participation in water and sanitation interventions impacts the availability of safe water and sanitation, a change in health status or behaviour and the longevity of water, sanitation and hygiene (WASH) resources and services.

DESIGN

Realist review.

DATA SOURCES

PubMed, Web of Science and Scopus databases were used to identify papers from low-income and middle-income countries from 2010 to 2020.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Criteria were developed for papers to be included. The contribution of each paper was assessed based on its relevance and rigour (eg, can it contribute to context, mechanism or outcome, and is the method used to generate that information credible).

ANALYSIS

Inductive and deductive coding was used to generate context-mechanism-outcome configurations.

RESULTS

73 studies conducted in 29 countries were included. We identified five mechanisms that explained the availability, change and longevity outcomes: (1) accountability (policies and procedures to hold communities responsible for their actions and outcomes of an intervention), (2) diffusion (spread of an idea or behaviour by innovators over time through communication among members of a community), (3) market (the interplay between demand and supply of a WASH service or resource), (4) ownership (a sense of possession and control of the WASH service or resource) and (5) shame (a feeling of disgust in one's behaviour or actions). Contextual elements identified included community leadership and communication, technical skills and knowledge, resource access and dependency, committee activity such as the rules and management plans, location and the level of community participation.

CONCLUSIONS

The findings highlight five key mechanisms impacted by 19 contextual factors that explain the outcomes of community water and sanitation interventions. Policymakers, programme implementers and institutions should consider community dynamics, location, resources, committee activity and practices and nature of community participation, before introducing community water and sanitation interventions.

Gun violence in Australia, 2002-2016: a cohort study

OBJECTIVES

To describe the burden, geographic distribution, and outcomes of firearm-related violence in New South Wales during 2002-2016.

DESIGN, SETTING, PARTICIPANTS

Population-based record linkag study of people injured by firearms in NSW, 1 January 2002 - 31 December 2016.

MAIN OUTCOME MEASURES

Frequency, proportion, and rate of firearm-related injuries and deaths by intent category (assault, intentional self-harm, accidental, undetermined/other) and socio-demographic characteristics; medical service use (hospitalisations, ambulatory mental health care) before and after firearm-related injuries; associations between rates of firearm-related injury and those of licensed gun owners, by statistical area level 4.

RESULTS

Firearm-related injuries were recorded for 2390 people; for 849 people, the injuries were caused by assault (36%), for 797 by intentional self-harm (33%), and for 506 by accidents (21%). Overall rates of firearm injuries were 4.1 per 100 000 males and 0.3 per 100 000 females; the overall rate was higher in outer regional/rural/remote areas (3.8 per 100 000) than in major cities (1.6 per 100 000) or inner regional areas (1.8 per 100 000). During 2002-2016, the overall firearm-related injury rate declined from 3.4 to 1.8 per 100 000 population, primarily because of declines in injuries caused by assault or accidental events. The rate of self-harm injuries with firearms were highest for people aged 60 years or more (41.5 per 100 000 population). Local rates of intentional self-harm injuries caused by firearms were strongly correlated with those of licensed gun owners (r = 0.94).

CONCLUSIONS

Rates of self-harm with firearms are higher for older people, men, and residents in outer regional and rural/remote areas, while those for assault-related injuries are higher for younger people, men, and residents of major cities. Strategies for reducing injuries caused by self-harm and assault with firearms should focus on people at particular risk.

Standardised patient study to assess tuberculosis case detection within the private pharmacy sector in Vietnam

Background

Of the estimated 10 million people affected by (TB) each year, one-third are never diagnosed. Delayed case detection within the private healthcare sector has been identified as a particular problem in some settings, leading to considerable morbidity, mortality and community transmission. Using unannounced standardised patient (SP) visits to the pharmacies, we aimed to evaluate the performance of private pharmacies in the detection and treatment of TB.

Methods

A cross-sectional study was undertaken at randomly selected private pharmacies within 40 districts of Vietnam. Trained actors implemented two standardised clinical scenarios of presumptive TB and presumptive multidrug-resistant TB (MDR-TB). Outcomes were the proportion of SPs referred for medical assessment and the proportion inappropriately receiving broad-spectrum antibiotics. Logistic regression evaluated predictors of SPs’ referral.

Results

In total, 638 SP encounters were conducted, of which only 155 (24.3%) were referred for medical assessment; 511 (80·1%) were inappropriately offered antibiotics. A higher proportion of SPs were referred without having been given antibiotics if they had presumptive MDR-TB (68/320, 21.3%) versus presumptive TB (17/318, 5.3%; adjusted OR=4.8, 95% CI 2.9 to 7.8). Pharmacies offered antibiotics without a prescription to 89.9% of SPs with presumptive TB and 70.3% with presumptive MDR-TB, with no clear follow-up plan.

Conclusions

Few SPs with presumptive TB were appropriately referred for medical assessment by private pharmacies. Interventions to improve appropriate TB referral within the private pharmacy sector are urgently required to reduce the number of undiagnosed TB cases in Vietnam and similar high-prevalence settings.

Behaviors and Attitudes Toward Smoking Among Health Care Workers at Health Facilities in 4 Provinces of Vietnam: A Representative Cross-Sectional Survey

Tobacco smoking is a leading cause of premature death. Smoking prevalence in Vietnam ranks among the highest in Southeast Asia. Given the important role of health care workers (HCWs) in promoting and supporting smoking cessation, this project aimed to characterize the prevalence of smoking among HCWs in Vietnam, and their attitudes toward smoking cessation interventions. A cross-sectional survey was conducted among care workers in 4 levels of the health system, within 4 provinces of Vietnam. Descriptive statistics evaluated participant attitudes, perception, behaviors, and knowledge about smoking. Multivariable logistic regression models evaluated risk factors for smoking. Among 3343 HCWs, 7.5% identified as current smokers, comprising 22.2% males and 0.5% of females. Males had substantially greater odds (adjusted odds ratio = 55.3; 95% confidence interval = 29.0-105.6) of identifying as current smokers compared with females. HCWs in urban settings had higher odds of identifying as smokers compared with rural workers (adjusted odds ratio = 1.72; 95% confidence interval = 1.23-2.24). Strong support for smoking cessation policies and interventions were identified, even among staff who smoked. HCWs play an integral role in identifying smokers and supporting smoking cessation interventions for their patients. Efforts to support affordable smoking cessation interventions within health facilities are likely to contribute to a reduction in smoking prevalence in Vietnam.

What are the most effective community-based antimicrobial stewardship interventions in low- and middle-income countries? A narrative review

Antimicrobial resistance (AMR) is a major global issue and antimicrobial stewardship is central to tackling its emergence. The burden of AMR disproportionately impacts low- and middle-income countries (LMICs), where capacity for surveillance and management of resistant pathogens is least developed. Poorly regulated antibiotic consumption in the community is a major driver of AMR, especially in LMICs, yet community-based interventions are neglected in stewardship research, which is often undertaken in high-income settings and/or in hospitals. We reviewed the evidence available to researchers and policymakers testing or implementing community-based antimicrobial stewardship strategies in LMICs. We critically appraise that evidence, deliver recommendations and identify outstanding areas of research need. We find that multifaceted, education-focused interventions are likely most effective in our setting. We also confirm that the quality and quantity of community-based stewardship intervention research is limited, with research on microbiological, clinical and economic sustainability most urgently needed.

Factors affecting healthcare pathways for chronic lung disease management in Vietnam: a qualitative study on patients' perspectives

BACKGROUND

Chronic obstructive pulmonary disease (COPD) and asthma rank among the leading causes of respiratory morbidity, particularly in low- and middle-income countries. This qualitative study aimed to explore the healthcare pathways of patients with chronic respiratory disease, and factors influencing their ability to access healthcare in Vietnam, where COPD and asthma are prevalent.

METHODS

We conducted 41 in-depth interviews among patients, including 31 people with COPD, eight with asthma and two with asthma-COPD overlap syndrome. Participants were recruited at provincial- or national-level health facilities in two urban and two rural provinces in Vietnam. The interviews were audio-recorded, transcribed, and analysed using thematic analysis.

RESULTS

Patients' healthcare pathways were complex and involved visits to multiple health facilities before finally obtaining a definitive diagnosis at a provincial- or national-level hospital. Access to healthcare was affected considerably by participants' limited knowledge of their respiratory conditions, the availability of social support, especially from family members, the costs of healthcare as well as health system factors (including the coverage of public health insurance, the distance to health facilities, and attitude of healthcare providers).

CONCLUSION

The study demonstrated the need for improved access to timely diagnosis and treatment of chronic lung disease within the lower level of the health system. This can be achieved by enhancing the communication skills and diagnostic capacity of local healthcare workers. Health education programmes for patients and caregivers will contribute to improved control of lung disease.

Smoking behaviour among adult patients presenting to health facilities in four provinces of Vietnam

Background

Attendance at healthcare facilities provides an opportunity for smoking cessation interventions. However, the smoking behaviours of patients seeking healthcare in Vietnam are not well-understood. We aimed to evaluate behaviours related to smoking among patients presenting to health facilities in Vietnam.

Methods

We conducted a cross-sectional study in 4 provinces of Vietnam. Consecutive patients aged ≥15 years presenting to 46 health facilities were assessed. Current smokers were randomly selected to complete a full survey about smoking behaviour, quit attempts, and preparedness to quit.

Results

Among 11,245 patients who sought healthcare, the prevalence of current smoking was 18.6% (95% CI: 17.8–19.4%) overall, 34.6% (95% CI: 33.2–36.0%) among men and 1.1% (95% CI: 0.8–1.3%) among women. Current smokers who were asked about smoking by healthcare providers in the last 12 months were more likely to make quit attempts than those not asked (40.6% vs 31.8%, p = 0.017). Current smokers who attempted to quit in the past 12 months made limited use of cessation aids: counselling (1.9%) and nicotine replacement therapy (10%). A higher proportion of patients wanted to quit in the next month at national/provincial hospitals (30.3%) than those visiting district hospitals (11.3%, p < 0.001) and commune health centres (11.1%, p = 0.004).

Conclusions

Smoking is common among male patients presenting to healthcare facilities in Vietnam. Formal smoking cessation supports are generally not used or offered. This population is likely to benefit from routine smoking cessation interventions that are integrated within the routine healthcare delivery system.

Health Risks, Preventive Behaviours and Respiratory Illnesses at the 2019 Arbaeen: Implications for COVID-19 and Other Pandemics

COVID-19 poses grave challenges for mass gatherings. One of the world’s largest annual gatherings, Arbaeen, occurs in Iraq. We studied respiratory symptoms and risk and protective factors using representative sampling of Arbaeen pilgrims in 2019 to inform prevention of COVID-19 transmission. Structured sampling was used to recruit walking pilgrims. A questionnaire asked about respiratory symptoms, risk, and preventive factors, including hygiene-related resources of toilet facilities. The commonest symptom reported by the 1842 participants (63.3% male, 36.7% female) was cough (25.6%). Eating in mawkibs (rest areas) with indoor kitchens and drinking only packaged water were associated with lower risk of cough (AOR = 0.72, CI = 0.56–0.94; AOR = 0.60; CI = 0.45–0.78, p < 0.05). Facemask use was associated with increased risk of cough (AOR = 2.71, CI = 2.08–3.53, p < 0.05). Handwashing was not protective against cough, or against (one or more of) cough, fever, or breathlessness in multivariate analysis. Toilet facilities often lacked running water (32.1%) and soap (26.1%), and had shared hand towels (17%). To reduce risk of respiratory infections including COVID-19 during Arbaeen or other mass gatherings, needs include running water, soap, and hygienic hand drying options or hand sanitiser. Education on proper handwashing and facemask approaches and monitoring around food preparation and eating spaces are needed.

Systemic Inflammation (C-Reactive Protein) in Older Chinese Adults Is Associated with Long-Term Exposure to Ambient Air Pollution

There is an established association between air pollution and cardiovascular disease (CVD), which is likely to be mediated by systemic inflammation. The present study evaluated links between long-term exposure to ambient air pollution and high-sensitivity C reactive protein (hs-CRP) in an older Chinese adult cohort (n = 7915) enrolled in the World Health Organization (WHO) study on global aging and adult health (SAGE) China Wave 1 in 2008–2010. Multilevel linear and logistic regression models were used to assess the associations of particulate matter (PM) and nitrogen dioxide (NO₂) on log-transformed hs-CRP levels and odds ratios of CVD risk derived from CRP levels adjusted for confounders. A satellite-based spatial statistical model was applied to estimate the average community exposure to outdoor air pollutants (PM with an aerodynamic diameter of 10 μm or less (PM₁₀), 2.5 μm or less (PM_2.5), and 1 μm or less (PM₁) and NO₂) for each participant of the study. hs-CRP levels were drawn from dried blood spots of each participant. Each 10 μg/m³ increment in PM₁₀, PM_2.5, PM₁, and NO₂ was associated with 12.8% (95% confidence interval; (CI): 9.1, 16.6), 15.7% (95% CI: 10.9, 20.8), 10.2% (95% CI: 7.3, 13.2), and 11.8% (95% CI: 7.9, 15.8) higher serum levels of hs-CRP, respectively. Our findings suggest that air pollution may be an important factor in increasing systemic inflammation in older Chinese adults.

A syndromic approach to assess diagnosis and management of patients presenting with respiratory symptoms to healthcare facilities in Vietnam

Background

The aim of the study was to establish syndromic diagnoses in patients presenting with respiratory symptoms to healthcare facilities in Vietnam and to compare the diagnoses with facility-level clinical diagnoses and treatment decisions.

Methods

A representative sample of patients aged ≥5 years, presenting with dyspnoea, cough, wheezing, and/or chest tightness to healthcare facilities in four provinces of Vietnam were systematically evaluated. Eight common syndromes were defined using data obtained.

Results

We enrolled 977 subjects at 39 facilities. We identified fixed airflow limitation (FAL) in 198 (20.3%) patients and reversible airflow limitation (RAL) in 26 (2.7%) patients. Patients meeting the criteria for upper respiratory tract infection (URTI) alone constituted 160 (16.4%) patients and 470 (48.1%) did not meet the criteria for any of the syndromes. Less than half of patients with FAL were given long-acting bronchodilators. A minority of patients with either RAL or FAL with eosinophilia were prescribed inhaled corticosteroids. Antibiotics were given to more than half of all patients, even among those with URTI alone.

Conclusion

This study identified a substantial discordance between prescribed treatment, clinician diagnosis and a standardised syndromic diagnosis among patients presenting with respiratory symptoms. Increased access to spirometry and implementation of locally relevant syndromic approaches to management may help to improve patient care in resource-limited settings.

This study identified discordance between a standardised syndromic diagnosis of respiratory diseases and the diagnosis reached within the Vietnamese health system. Implementing a syndromic approach to case management might help to improve patient care.https://bit.ly/36oJORg

An Analysis of Healthy Food Access Amongst Women in Peri-urban Honiara

Highly processed and energy-dense foods are contributing to the high and rising rates of non-communicable diseases and nutrient deficiencies in Solomon Islands. Non-communicable diseases currently cause 69% of deaths in Solomon Islands, and the rate is rising, fuelled in part by limited health system capacity to treat these conditions. Solomon Islands also has the highest reported undernourishment rate in the Pacific. Recent decades have seen several factors change the food and economic environment in Solomon Islands. Importantly, rural-to-urban migration has caused a disconnect between urban residents and access to land and home gardens. This study aimed to examine the complexities of nutritious food access in urban Solomon Islands. Data were collected from 32 women in Honiara, the islands' capital, using a novel survey instrument. There were 3 important findings: (1) the dominant influencers of the diet patterns described by participants in this study were food affordability and access to land on which to grow it, (2) all participants experienced food insecurity, and (3) reported diet patterns reflected unhealthy diets which were particularly high in processed and sugary foods. These findings suggest a need for improvements in the food environment in Honiara.

Indian Public Health Students' Perspectives on Global Health Education

Global health discipline is of increasing interest for educators and students in public health across the world. Public health education is recently gaining momentum in India, but global health is still at an embryonic stage. Value of students as stakeholders in curriculum development is increasingly recognized but literature about perspectives of public health students regarding global health education is limited. This study aimed to explore Indian public health students' perspectives about global health education and to provide platform for the development of global health education framework for future public health professionals. This study involved a series of focus groups with students and sought to understand perceptions about global health and global health education framework. We recruited public health students at three institutes across India for focus group discussions. Focus groups questions covered current understanding of global health, opinions regarding global health education for public health curriculum and the relevance of global health competency domains for future employment. Recordings were transcribed verbatim and the transcripts were read along with field notes and then analyzed thematically. A total of 36 students participated in four focus groups. There was a general recognition that global health is transnational and that a global outlook is now essential. But there were concerns regarding local and global priorities in public health. Global health was regarded as being wider than public health by some, but others viewed public health being the umbrella term with global health as a specialization. Global health competencies were viewed as a “step up” from the public health competencies but core public health competencies were considered essential. International experiences and use of technology were key themes for delivery of global health education. Employability and career progression for global health graduates were of concern for many participants. This study provides insight into the student perspectives regarding global health education for public health programs in India. Clear direction in terms of curriculum and its utility for career growth and employability as a global health professional needs to be established for global health education in India and other similar settings.

Ambient air pollution, lung function and COPD: cross-sectional analysis from the WHO Study of AGEing and adult health wave 1

BACKGROUND

Long-term exposure to ambient air pollution leads to respiratory morbidity and mortality; however, the evidence of the effect on lung function and chronic obstructive pulmonary disease (COPD) in older adult populations is inconsistent.

OBJECTIVE

To address this knowledge gap, we investigated the associations between particulate matter (PM), nitrogen dioxide (NO2) exposure and lung function, as well as COPD prevalence, in older Chinese adults.

METHODS

We used data from the WHO Study on global AGEing and adult health (SAGE) China Wave 1, which includes 111 693 participants from 64 townships in China. A cross-sectional analysis explored the association between satellite-based air pollution exposure estimates (PM with an aerodynamic diameter of ≤10 µm [PM10], ≤2.5 µm [PM2.5] and NO2) and forced expiratory volume in one second (FEV1), forced vital capacity (FVC), the FEV1/FVC ratio and COPD (defined as post-bronchodilator FEV1/FVC <70%). Data on lung function changes were further stratified by COPD status.

RESULTS

Higher exposure to each pollutant was associated with lower lung function. An IQR (26.1 µg/m3) increase in PM2.5 was associated with lower FEV1 (-71.88 mL, 95% CI -92.13 to -51.64) and FEV1/FVC (-2.81 mL, 95% CI -3.37 to -2.25). For NO2, an IQR increment of 26.8 µg/m3 was associated with decreases in FEV1 (-60.12 mL, 95% CI -84.00 to -36.23) and FVC (-32.33 mL, 95% CI -56.35 to -8.32). A 31.2 µg/m3 IQR increase in PM10 was linked to reduced FEV1 (-8.86 mL, 95% CI -5.40 to 23.11) and FEV1/FVC (-1.85 mL, 95% CI -2.24 to -1.46). These associations were stronger for participants with COPD. Also, COPD prevalence was linked to higher levels of PM2.5 (POR 1.35, 95% CI 1.26 to 1.43), PM10 (POR 1.24, 95% CI 1.18 to 1.29) and NO2 (POR 1.04, 95% CI 0.98 to 1.11).

CONCLUSION

Ambient air pollution was associated with lower lung function, especially in individuals with COPD, and increased COPD prevalence in older Chinese adults.

Ambient air pollution exposure association with diabetes prevalence and glycosylated hemoglobin (HbA1c) levels in China. Cross-sectional analysis from the WHO study of AGEing and adult health wave 1

Over the past decades, air pollution has become one of the critical environmental health issues in China. The present study aimed to evaluate links between ambient air pollution and the prevalence of type 2 diabetes mellitus (T2DM) and the levels of glycosylated hemoglobin (HbA1c). A multilevel linear and logistic regression was used to assess these associations among 7,770 participants aged ≥50 years from the WHO Study on global AGEing and adult health (SAGE) in China in 2007-2010. The average exposure to each of pollutants (particulate matter with an aerodynamic diameter of ≤10 μm/≤2.5 μm/≤1 μm [PM₁₀/PM_2.5/PM₁] and nitrogen dioxide [NO₂]) was estimated using a satellite-based spatial statistical model. In logistic models, a 10 µg/m³ increase in PM₁₀ and PM_2.5 was associated with increased T2DM prevalence (Prevalence Odds Ratio, POR: 1.27; 95% CI: 1.11, 1.45 and POR: 1.23; 95% CI: 1.03, 1.46). Similar increments in PM₁₀, PM_2.5, PM₁ and NO₂ were associated with increase in HbA1c levels of 1.8% (95% CI: 1.3, 2.3), 1.3% (95% CI: 1.1, 1.5), 0.7% (95% CI: 0.1, 1.3), and 0.8% (95% CI: 0.4, 1.2), respectively. In a large cohort of older Chinese adults, air pollution was liked to both higher T2DM prevalence and elevated HbA1c levels.

Ambient Air Pollution Exposure Association with Anaemia Prevalence and Haemoglobin Levels in Chinese Older Adults

BACKGROUND

Health effects of air pollution on anaemia have been scarcely studied worldwide. We aimed to explore the associations of long-term exposure to ambient air pollutants with anaemia prevalence and haemoglobin levels in Chinese older adults.

METHODS

We used two-level linear regression models and modified Poisson regression with robust error variance to examine the associations of particulate matter (PM) and nitrogen dioxide (NO₂) on haemoglobin concentrations and the prevalence of anaemia, respectively, among 10,611 older Chinese adults enrolled in World Health Organization (WHO) Study on global AGEing and adult health (SAGE) China. The average community exposure to ambient air pollutants (PM with an aerodynamic diameter of 10 μm or less (PM₁₀), 2.5 μm or less (PM_2.5), 1 μm or less (PM₁) and nitrogen dioxide (NO₂)) for each participant was estimated using a satellite-based spatial statistical model. Haemoglobin levels were measured for participants from dried blood spots. The models were controlled for confounders.

RESULTS

All the studied pollutants were significantly associated with increased anaemia prevalence in single pollutant model (e.g., the prevalence ratios associated with an increase in inter quartile range in three years moving average PM₁₀ (1.05; 95% CI: 1.02-1.09), PM_2.5 (1.11; 95% CI: 1.06-1.16), PM₁ (1.13; 95% CI: 1.06-1.20) and NO₂ (1.42; 95% CI: 1.34-1.49), respectively. These air pollutants were also associated with lower concentrations of haemoglobin: PM₁₀ (-0.53; 95% CI: -0.67, -0.38); PM_2.5 (-0.52; 95% CI: -0.71, -0.33); PM₁ (-0.55; 95% CI: -0.69, -0.41); NO₂ (-1.71; 95% CI: -1.85, -1.57) respectively.

CONCLUSIONS

Air pollution exposure was significantly associated with increased prevalence of anaemia and decreased haemoglobin levels in a cohort of older Chinese adults.

Social engagement pattern, health behaviors and subjective well-being of older adults: an international perspective using WHO-SAGE survey data

BACKGROUND

Social engagement forms the basis of social relationships by providing a sense of belonging, social identity, and fulfillment. Previous research demonstrates that social engagement was associated with positive health behaviors among older adults. However, the results have been different across health-related behaviors, and mostly based on data from high-income countries. For example, studies from the US and UK showed that social engagement was protective against smoking, while others found social engagement encouraged more smoking in many Asian cultures. In this study, we aim to examine the association between social engagement and a range of health-related behaviors and subjective well-being among older adults in six low- to middle-income countries.

METHODS

Data from the WHO Study on Global Ageing and Adult Health (SAGE Wave 1) were used. A total of 33,338 individuals aged 50 and older in China, Russia, India, Ghana, South Africa, and Mexico were included. Social engagement, tobacco use, alcohol consumption, fruit and vegetable intake, physical activity, sedentary behavior, sleep duration, depression symptoms, self-rated health status, and quality of life were assessed using established self-reported measures. Multiple logistic regression models were used to examine the relationship between social engagement and nine outcome variables, adjusting for socio-demographic characteristics.

RESULTS

Lower levels of social engagement were positively related to physical inactivity, prolonged sitting time, unhealthy sleep duration, perceived depression, poor self-rated health, and low quality of life. However, the associations between social engagement and tobacco use, excessive drinking, and insufficient fruit and vegetable intake were mixed across countries.

CONCLUSION

This international study found high social engagement as a potential health-promoting factor in some low- to middle-income countries. Although the impacts of social engagement on tobacco and alcohol use and diet were complicated and culture-specific, interventions at both individual and community levels should encourage healthy lifestyles through positive social engagement.

Arbaeen public health concerns: A pilot cross-sectional survey

BACKGROUND

Arbaeen is an annual religious procession in Iraq with an estimated 17-20 million participants. Public health risks associated with such a mass gathering can be serious at both local and global levels. This is the first quantitative examination of risk factors for, and symptoms of, infectious disease among Arbaeen participants.

METHODS

A cross-sectional survey was conducted of a convenience sample of 191 Arbaeen participants in 2017. Interviewers administered a structured questionnaire. Questions included food sources, preventive measures used and symptoms of infectious diseases during the procession.

RESULTS

Data were collected for 191 participants (143 males, 58 females). The most prevalent symptoms were respiratory (runny nose: 22.6%, cough: 22.5%). Diarrhoea was reported by 12.6% of participants, with a strong association with high-income country origin and eating (commercial) street food (odds ratios 6.1 and 4.1, respectively, p < 0.05). All symptoms investigated, except breathlessness, were more prevalent in high-income country participants (p < 0.05).

CONCLUSION

Street food and high-income country origin were independent risk factors for respiratory or gastrointestinal infection symptoms in this sample of Arbaeen participants. However, these results cannot be generalised due to possible selection bias. Further studies are required to inform policy development and health system preparedness to reduce Arbaeen-associated health risks.

Tracking the leavers: towards a better understanding of doctor migration from Ireland to Australia 2008-2018

BACKGROUND

The recession of 2008 triggered large-scale emigration from Ireland. Australia emerged as a popular destination for Irish emigrants and for Irish-trained doctors. This paper illustrates the impact that such an external shock can have on the medical workforce and demonstrates how cross-national data sharing can assist the source country to better understand doctor emigration trends.

METHOD

This study draws on Australian immigration, registration and census data to highlight doctor migration flows from Ireland to Australia, 2008-2018.

FINDINGS

General population migration from Ireland to Australia increased following the 2008 recession, peaked between 2011 and 2013 before returning to pre-2008 levels by 2014, in line with the general economic recovery in Ireland. Doctor emigration from Ireland to Australia did not follow the same pattern, but rather increased in 2008 and increased year on year since 2014. In 2018, 326 Irish doctors obtained working visas for Australia. That doctor migration is out of sync with general economic conditions in Ireland and with wider migration patterns indicates that it is influenced by factors other than evolving economic conditions in Ireland, perhaps factors relating to the health system.

DISCUSSION

Doctor emigration from Ireland to Australia has not decreased in line with improved economic conditions in Ireland, indicating that other factors are driving and sustaining doctor emigration. This paper considers some of these factors. Largescale doctor emigration has significant implications for the Irish health system; representing a brain drain of talent, generating a need for replacement migration and a high dependence on internationally trained doctors. This paper illustrates how source countries, such as Ireland, can use destination country data to inform an evidence-based policy response to doctor emigration.

Health system preparedness for emerging infectious diseases: A synthesis of the literature

This review reflects on what the literature to date has taught us about how health systems of low- and middle-income countries (LMICs) respond to emerging infectious disease (EID) outbreaks. These findings are then applied to propose a conceptual framework characterising an EID prepared health system. A narrative synthesis approach was adopted to explore the key elements of LMIC health systems during an EID outbreak. Overarching themes ('core health system constructs') and sub-themes ('elements') relevant to EID preparedness were extracted from 49 peer-reviewed articles. The resulting conceptual framework recognised six core constructs: four focused on material resources and structures (i.e. system 'hardware'), including (i) Surveillance, (ii) Infrastructure and medical supplies, (iii) Workforce, and (iv) Communication mechanisms; and two focused on human and institutional relationships, values and norms (i.e. system 'software'), including (i) Governance, and (ii) Trust. The article reinforces the interconnectedness of the traditional health system building blocks to EID detection, prevention and response, and highlights the critical role of system 'software' (i.e. governance and trust) in enabling LMIC health systems to achieve and maintain EID preparedness. The review provides recommendations for refining a set of indicators for an 'optimised' health system EID preparedness tool to aid health system strengthening efforts.

Advancing Planetary Health in Australia: focus on emerging infections and antimicrobial resistance

With rising population numbers, anthropogenic changes to our environment and unprecedented global connectivity, the World Economic Forum ranks the spread of infectious diseases second only to water crises in terms of potential global impact. Addressing the diverse challenges to human health and well-being in the 21st century requires an overarching focus on ‘Planetary Health’, with input from all sectors of government, non-governmental organisations, academic institutions and industry. To clarify and advance the Planetary Health agenda within Australia, specifically in relation to emerging infectious diseases (EID) and antimicrobial resistance (AMR), national experts and key stakeholders were invited to a facilitated workshop. EID themes identified included animal reservoirs, targeted surveillance, mechanisms of emergence and the role of unrecognised human vectors (the ‘invisible man’) in the spread of infection. Themes related to AMR included antimicrobial use in production and companion animals, antimicrobial stewardship, novel treatment approaches and education of professionals, politicians and the general public. Effective infection control strategies are important in both EID and AMR. We provide an overview of key discussion points, as well as important barriers identified and solutions proposed.

Access to a Nutritious Diet in Samoa: Local Insights

The adult obesity prevalence in Samoa is the third highest globally, and diet is a significant contributor. Our study aimed to explore the behavioral and demographic factors which influence diets in Samoa. The most important findings for strategic policy design were: i) cost was the most important reason for food choice, ii) participants reported high rates of consumption of sugary and fatty energy foods - along with high rates of food insecurity, and iii) the food frequency questionnaire findings from our small sample are in line with the existing evidence that the nutrition transition is underway in Samoa.

Women's autonomy and utilisation of maternal healthcare services in 31 Sub-Saharan African countries: results from the demographic and health surveys, 2010-2016

OBJECTIVES

To examine the association between women's autonomy and the utilisation of maternal healthcare services across 31 Sub-Saharan African countries.

DESIGN, SETTING AND PARTICIPANTS

We analysed the Demographic and Health Survey (DHS) (2010-2016) data collected from married women aged 15-49 years. We used four DHS measures related to women's autonomy: attitude towards domestic violence, attitude towards sexual violence, decision making on spending of household income made by the women solely or jointly with husbands and decision making on major household purchases made by the women solely or jointly with husbands. We used multiple logistic regression analyses to examine the association between women's autonomy and the utilisation of maternal healthcare services adjusted for five potential confounders: place of residence, age at birth of the last child, household wealth, educational attainment and working status. Adjusted ORs (aORs) and 95% CI were used to produce the forest plots.

OUTCOME MEASURES

The primary outcome measures were the utilisation of ≥4 antenatal care visits and delivery by skilled birth attendants (SBA).

RESULTS

Pooled results for all 31 countries (194 883 women) combined showed weak statistically significant associations between all four measures of women's autonomy and utilisation of maternal healthcare services (aORs ranged from 1.07 to 1.15). The strongest associations were in the Southern African region. For example, the aOR for women who made decisions on household income solely or jointly with husbands in relation to the use of SBAs in the Southern African region was 1.44 (95% CI 1.21 to 1.70). Paradoxically, there were three countries where women with higher autonomy on some measures were less likely to use maternal healthcare services. For example, the aOR in Senegal for women who made decisions on major household purchases solely or jointly with husbands in relation to the use of SBAs (aOR=0.74 95% CI 0.59 to 0.94).

CONCLUSION

Our results revealed a weak relationship between women's autonomy and the utilisation of maternal healthcare services. More research is needed to understand why these associations are not stronger.

How food insecurity could lead to obesity in LMICs: When not enough is too much: a realist review of how food insecurity could lead to obesity in low- and middle-income countries

While food insecurity is a well-known cause of under-nutrition and stunting, in recent decades it has also been linked with obesity. Understanding and thus minimising the risk factors for obesity in low- and middle-income country contexts, which often lack the health system capacity to treat the consequent obesity-related illnesses, is crucial. This study adopted realist review methodology because it enabled us to analyse and organise the evidence from low- and middle-income countries into a coherent scheme. By comparing this evidence to existing theory on food security and nutrition, we aimed to provide a richer understanding of the nuances and the socio-demographic nature of the food insecurity-obesity relationship. The review generated 13 peer-reviewed articles which studied the relationship between food insecurity and overweight/obesity in low- and middle-income countries. Affordability of high-energy, processed foods was identified as a main mechanism, which determined whether or not food insecurity leads to obesity in low- and middle-income countries. Other mechanisms identified were: quantity and diversity of food consumed; spatial-temporal access to nutritious food; inter-personal food choice and distribution; and non-dietary behaviours. Despite the limited empirical evidence available, our review presents meaningful and policy-relevant insights into the food insecurity-obesity relationship in from low- and middle-income countries. Interventions to address the food insecurity-obesity link need to address diet quality, and demand a broad understanding across a variety of experiences.

HIV prevalence and related behaviours of older people in Botswana - secondary analysis of the Botswana AIDS Impact Survey (BAIS) IV

The focus of HIV interventions in Botswana, a country with the second highest prevalence of HIV in the world, remains targeted at those aged 15-49 years despite a growing cohort of older people living with the disease - driven largely by the successful roll-out of antiretroviral therapy (ART). Primarily utilising the Botswana AIDS Impact Survey IV, we set out to examine HIV related characteristics and behaviours of this often ignored older cohort (50-64 years) relative to younger (25-49 years) adults. Analysis revealed that more than 80% of older people living with HIV were on ART. HIV prevalence among this older cohort was 24.6% in 2013 compared to 35.1% among the younger cohort, p < 0.0001. Prevalence in older adults was higher among older males (27.8%) than females (21.9%), p = 0.02. Furthermore, 58.9% of older adults acknowledged being sexually active, with 59.0% of these admitting to inconsistent condom use during sexual intercourse. In addition to this low condom usage, older men (6.0%) were significantly more likely to be unaware of their HIV-positive status than older women (3.0%), p = 0.002. While HIV prevalence showed a dramatic increase among older men over time (17.2% in 2004, to 23.4% in 2008, to 27.8% in 2013), the trend was flatter among older women (16.3% in 2004, to 22.4% in 2008, to 21.9% in 2013). These trends are likely attributable to a large increase in ART coverage and uptake. Going forward, more targeted interventions acknowledging the ageing epidemic are important to consider.

"For us here, we remind ourselves": strategies and barriers to ART access and adherence among older Ugandans

BACKGROUND

Very little is known about the barriers and facilitators to antiretroviral therapy (ART) access and adherence among older Africans. Most studies on ART have focused on individuals who are 15-49 years of age.

METHODS

We used in-depth interviews with 40 persons living with HIV, aged 50 to 96 years, who had either initiated ART (n = 26) or were waiting to initiate ART (n = 14), to explore barriers and facilitators to ART access and adherence in rural Uganda.

RESULTS

Guided by the Andersen Behavior Model, thematic content analysis highlighted 21 primary factors related to environment, patient and health behavior. Nine of the factors were common to both access and adherence, the remaining 12 were evenly split between access and adherence. Transportation costs, food insecurity, and healthcare workers' knowledge, attitudes and behaviors were key barriers.

CONCLUSIONS

These barriers were similar to those outlined for younger populations in other studies, but were compounded by age. Despite barriers, either due to the exceptional nature of HIV care or overreporting, both ART access and self-reported adherence were better than expected. Older persons living with HIV highlighted health care needs for non-HIV-related illnesses, suggesting while HIV care is adequate, care for the ailments of "old age" is lagging.

Social engagement and survival in people aged 50 years and over living with HIV and without HIV in Uganda: a prospective cohort study

This study examined the association between social engagement and survival in people with or without HIV aged 50 years and over in Uganda. We analysed two waves of a survey from two sites in Uganda to assess predictors of mortality between waves. The first wave was conducted between 2009 and 2010 while the second wave was conducted between 2012 and 2013. A standardised questionnaire adapted from the World Health Organization study on global AGEing and adult health (SAGE) was administered through face-to-face interviews at both survey waves. Cox proportional hazards models and Nelson-Aalen cumulative hazards functions were used to investigate associations between the strength of participants' social ties, using distance and intimacy metrics, and their social engagement with mortality between waves. Of the original 510 participants, 63 (12.3%) died between waves. Being more socially engaged and able to provide in-kind or financial contributions to family or friends were protective. After adjusting for covariates neither social tie measure was predictive of mortality. There were no significant differences in social engagement and survival by HIV status. Further research is needed in African settings on the relationship between social relationships and subsequent mortality in older adults to assess if improved social relationships could moderate mortality.

How to assess and prepare health systems in low- and middle-income countries for integration of services-a systematic review

Despite growing support for integration of frontline services, a lack of information about the pre-conditions necessary to integrate such services hampers the ability of policy makers and implementers to assess how feasible or worthwhile integration may be, especially in low- and middle-income countries (LMICs). We adopted a modified systematic review with aspects of realist review, including quantitative and qualitative studies that incorporated assessment of health system preparedness for and capacity to implement integrated services. We searched Medline via Ovid, Web of Science and the Cochrane library using terms adapted from Dudley and Garner’s systematic review on integration in LMICs. From an initial list of 10 550 articles, 206 were selected for full-text review by two reviewers who independently reviewed articles and inductively extracted and synthesized themes related to health system preparedness. We identified five ‘context’ related categories and four health system ‘capability’ themes. The contextual enabling and constraining factors for frontline service integration were: (1) the organizational framework of frontline services, (2) health care worker preparedness, (3) community and client preparedness, (4) upstream logistics and (5) policy and governance issues. The intersecting health system capabilities identified were the need for: (1) sufficiently functional frontline health services, (2) sufficiently trained and motivated health care workers, (3) availability of technical tools and equipment suitable to facilitate integrated frontline services and (4) appropriately devolved authority and decision-making processes to enable frontline managers and staff to adapt integration to local circumstances. Moving beyond claims that integration is defined differently by different programs and thus unsuitable for comparison, this review demonstrates that synthesis is possible. It presents a common set of contextual factors and health system capabilities necessary for successful service integration which may be considered indicators of preparedness and could form the basis for an ‘integration preparedness tool’.

Policy-maker attitudes to the ageing of the HIV cohort in Botswana

Background: The roll out of antiretroviral therapy in Botswana, as in many countries with near universal access to treatment, has transformed HIV into a complex yet manageable chronic condition and has led to the emergence of a population aging with HIV. Although there has been some realization of this development at international level, no clear defined intervention strategy has been established in many highly affected countries. Therefore we explored attitudes of policy-makers and service providers towards HIV among older adults (50 years or older) in Botswana. Methods: We conducted qualitative face-to-face interviews with 15 consenting personnel from the Ministry of Health, medical practitioners and non-governmental organizations involved in the administration of medical services, planning, strategies and policies that govern social, physical and medical intervention aimed at people living with HIV and health in general. The Shiffman and Smith Framework of how health issues become a priority was used as a guide for our analysis. Results: Amidst an HIV prevalence of 25% among those aged 50–64 years, the respondents passively recognized the predicament posed by a population aging with HIV but exhibited a lack of comprehension and acknowledgement of the extent of the issue. An underlying persistent ageist stigma regarding sexual behaviour existed among a number of interviewees. Respondents also noted the lack of defined geriatric care within the provision of the national health care system. There seemed, however, to be a debate among the policy strategists and care providers as to whether the appropriate response should be specifically towards older adults living with HIV or rather to improve health services for older adults more generally. Respondents acknowledged that health systems in Botswana are still configured for individual diseases rather than coexisting chronic diseases even though it has become increasingly common for patients, particularly the aged, to have two or more medical conditions at the same time. Conclusions: HIV among older adults remains a low priority among policy-makers in Botswana but is at least now on the agenda. Action will require more concerted efforts to recognize HIV as a lifelong infection and putting greater emphasis on targeted care for older adults, focussing on multimorbidity.

Effectiveness of SMS Technology on Timely Community Health Worker Follow-Up for Childhood Malnutrition: A Retrospective Cohort Study in sub-Saharan Africa

BACKGROUND

The Millennium Villages Project facilitated technology-based health interventions in rural under-resourced areas of sub-Saharan Africa. Our study examined whether data entry using SMS compared with paper forms by community health workers (CHWs) led to higher proportion of timely follow-up visits for malnutrition screening in under-5 children in Ghana, Rwanda, Senegal, and Uganda.

METHODS

Children under 5 years were screened for malnutrition every 90 days by CHWs using mid-upper arm circumference (MUAC) readings. CHWs used either SMS texts or paper forms to enter MUAC data. Reminder texts were sent at 15 days before follow-up was needed. Chi-square tests assessed proportion of timely follow-up visits within 90 days between SMS and paper groups. Logistic regression analysis was conducted in a step-wise multivariate model. Post-hoc power calculations were conducted to verify strength of associations.

RESULTS

SMS data entry was associated with a higher proportion of timely malnutrition follow-up visits compared with paper forms across all sites. The association was strongest with consistent SMS use over consecutive visits. SMS use at the first of 2 consecutive visits was most effective, highlighting the importance of SMS reminder alerts.

CONCLUSIONS

SMS technology with reminders increased timely CHW malnutrition screening visits for under-5 children in Ghana, Rwanda, Senegal, and Uganda, highlighting the importance of such technology for improving health worker behavior in low-resource settings.

Stakeholders' perspectives on facilitators of and barriers to the utilisation of and access to maternal health services in Eritrea: a qualitative study

BACKGROUND

Wars affect maternal health services by destroying health systems. Eritrea experienced two wars with neighbouring Ethiopia. Despite this, the maternal mortality ratio (MMR) in Eritrea fell by 69% from 1590 per 100,000 live births in 1990 to 501 in 2015. This study aimed to examine facilitators of and barriers to the utilisation of and access to maternal health services in Eritrea.

METHODS

Using in-depth interviews and field observations for data collection, this qualitative study was conducted in five healthcare facilities in Asmara, the capital of Eritrea, in February and March 2016. The participants were: women (n = 40), husbands (n = 5), healthcare providers (n = 10), and decision makers (n = 5).

RESULTS

There were two perceived facilitators of utilisation of and access to maternal health services: health education (related to the WHO health service delivery building blocks) and improvement in gender equality driven by the role played by Eritrean women as combatants during the War of Independence (1961-1991). The only perceived barrier was poor quality of care due to lack of ultrasound machines, short clinic opening hours, and shortage of healthcare workers (related to the WHO health workforce building block).

CONCLUSION

This study assessed women and their husbands/partners' perceptions and the possible effects of contemporary Eritrean culture and the history of war on the utilisation of and access to maternal health services in the country. As well, we examined healthcare providers' and decision makers' perspectives. The two key facilitators of women's utilisation of and access to maternal health services were health education and women's empowerment driven by their role as combatants during the War of Independence. One main barrier was poor quality of care due to lack of ultrasound machines, short clinic opening hours, and a shortage of healthcare workers. As only a limited number of qualitative studies have been published about maternal health services in war-affected sub-Saharan African countries, our findings regarding health education and women's empowerment could be considered in other war-affected countries similar to Eritrea. Nevertheless, further research is needed to investigate our findings - particularly regarding female empowerment driven by women's role in combat in relation to their maternal health.

Health system reforms in five sub-Saharan African countries that experienced major armed conflicts (wars) during 1990-2015: a literature review

BACKGROUND

Sub-Saharan Africa (SSA) has had more major armed conflicts (wars) in the past two decades - including 13 wars during 1990-2015 - than any other part of the world, and this has had an adverse effect on health systems in the region.

OBJECTIVE

To understand the best health system practices in five SSA countries that experienced wars during 1990-2015, and yet managed to achieve a maternal mortality reduction - equal to or greater than 50% during the same period - according to the Maternal Mortality Estimation Inter-Agency Group (MMEIG). Maternal mortality is a death of a woman during pregnancy, or within 42 days after childbirth - measured as maternal mortality ratio (MMR) per 100,000 live births.

DESIGN

We conducted a selective literature review based on a framework that drew upon the World Health Organisation's (WHO) six health system building blocks. We searched seven databases, Google Scholar as well as conducting a manual search of sources in articles' reference lists - restricting our search to articles published in English. We searched for terms related to maternal healthcare, the WHO six health system building blocks, and names of the five countries.

RESULTS

Our study showed three general health system reforms across all five countries that could explain MMR reduction: health systems decentralisation, the innovation related to the WHO workforce health system building block such as training of community healthcare workers, and governments-financing reforms.

CONCLUSION

Restoring health systems after disasters is an urgent concern, especially in countries that have experienced wars. Our findings provide insight from five war-affected SSA countries which could inform policy. However, since few studies have been conducted concerning this topic, our findings require further research to inform policy, and to help countries rebuild and maintain their health systems resilience.

Tuberculosis among older adults in Zambia: burden and characteristics among a neglected group

Background

The 2010 Global Burden of Disease estimates show that 57% of all TB deaths globally occurred among adults older than 50 years of age. Few studies document the TB burden among older adults in Southern Africa. We focused on adults older than 55 years to assess the relative TB burden and associated demographic factors.

Methods

A cross sectional nationally representative TB prevalence survey conducted of Zambian residents aged 15 years and above from 66 clusters across all the 10 provinces of Zambia. Evaluation included testing for TB as well as an in-depth questionnaire. We compared survey data for those aged 55 and older to those aged 15–54 years. Survey results were also compared with 2013 routinely collected programmatic notification data to generate future hypotheses regarding active and passive case finding.

Results

Among older adults with TB, 30/ 54 (55.6%) were male, 3/27 (11.1%) were HIV infected and 35/54 (64.8%) lived in rural areas. TB prevalence was higher in those aged ≥55 (0.7%) than in the 15–54 age group (0.5%). Males had higher rates of TB across both age groups with 0.7% (15–54) and 1.0% (≥55) compared with females 0.4% (15–54) and 0.6% (≥55). In rural areas, the prevalence of TB was significantly higher among older than younger adults (0.7% vs 0.3%), while the HIV infection rate was among TB patients was lower (11.1% vs 30.8%). The prevalence survey detected TB in 54/7484 (0.7%) of older adults compared to 3619/723,000 (0.5%) reported in 2013 programmatic data.

Conclusion

High TB rates among older adults in TB endemic areas justify consideration of active TB case finding and prevention strategies.

A Review of Global Health Competencies for Postgraduate Public Health Education

During the last decade, the literature about global health has grown exponentially. Academic institutions are also exploring the scope of their public health educational programs to meet the demand for a global health professional. This has become more relevant in the context of the sustainable development goals. There have been attempts to describe global health competencies for specific professional groups. The focus of these competencies has been variable with a variety of different themes being described ranging from globalization and health care, analysis and program management, as well as equity and capacity strengthening. This review aims to describe global health competencies and attempts to distill common competency domains to assist in curriculum development and integration in postgraduate public health education programs. A literature search was conducted using relevant keywords with a focus on public health education. This resulted in identification of 13 articles that described global health competencies. All these articles were published between 2005 and 2015 with six from the USA, two each from Canada and Australia, and one each from UK, Europe, and Americas. A range of methods used to describe competency domains included literature review, interviews with experts and employers, surveys of staff and students, and description or review of an academic program. Eleven competency domains were distilled from the selected articles. These competency domains primarily referred to three main aspects, one that focuses on burden of disease and the determinants of health. A second set focuses on core public health skills including policy development, analysis, and program management. Another set of competency domains could be classified as "soft skills" and includes collaboration, partnering, communication, professionalism, capacity building, and political awareness. This review presents the landscape of defined global health competencies for postgraduate public health education. The discussion about use of "global health," "international health," and "global public health" will continue, and academic institutions need to explore ways to integrate these competencies in postgraduate public health programs. This is critical in the post-MDG era that we prepare global public health workforce for the challenges of improving health of the "global" population in the context of sustainable development goals.

Chronic Noncommunicable Diseases in 6 Low- and Middle-Income Countries: Findings From Wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (SAGE)

In this paper, we examine patterns of self-reported diagnosis of noncommunicable diseases (NCDs) and prevalences of algorithm/measured test-based, undiagnosed, and untreated NCDs in China, Ghana, India, Mexico, Russia, and South Africa. Nationally representative samples of older adults aged ≥50 years were analyzed from wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (2007-2010; n = 34,149). Analyses focused on 6 conditions: angina, arthritis, asthma, chronic lung disease, depression, and hypertension. Outcomes for these NCDs were: 1) self-reported disease, 2) algorithm/measured test-based disease, 3) undiagnosed disease, and 4) untreated disease. Algorithm/measured test-based prevalence of NCDs was much higher than self-reported prevalence in all 6 countries, indicating underestimation of NCD prevalence in low- and middle-income countries. Undiagnosed prevalence of NCDs was highest for hypertension, ranging from 19.7% (95% confidence interval (CI): 18.1, 21.3) in India to 49.6% (95% CI: 46.2, 53.0) in South Africa. The proportion untreated among all diseases was highest for depression, ranging from 69.5% (95% CI: 57.1, 81.9) in South Africa to 93.2% (95% CI: 90.1, 95.7) in India. Higher levels of education and wealth significantly reduced the odds of an undiagnosed condition and untreated morbidity. A high prevalence of undiagnosed NCDs and an even higher proportion of untreated NCDs highlights the inadequacies in diagnosis and management of NCDs in local health-care systems.
