The impact of poverty and socioeconomic status on brain, behaviour, and development: a unified framework

In this article, we, for the first time, provide a comprehensive overview and unified framework of the impact of poverty and low socioeconomic status (SES) on the brain and behaviour. While there are many studies on the impact of low SES on the brain (including cortex, hippocampus, amygdala, and even neurotransmitters) and behaviours (including educational attainment, language development, development of psychopathological disorders), prior studies did not integrate behavioural, educational, and neural findings in one framework. Here, we argue that the impact of poverty and low SES on the brain and behaviour are interrelated. Specifically, based on prior studies, due to a lack of resources, poverty and low SES are associated with poor nutrition, high levels of stress in caregivers and their children, and exposure to socio-environmental hazards. These psychological and physical injuries impact the normal development of several brain areas and neurotransmitters. Impaired functioning of the amygdala can lead to the development of psychopathological disorders, while impaired hippocampus and cortex functions are associated with a delay in learning and language development as well as poor academic performance. This in turn perpetuates poverty in children, leading to a vicious cycle of poverty and psychological/physical impairments. In addition to providing economic aid to economically disadvantaged families, interventions should aim to tackle neural abnormalities caused by poverty and low SES in early childhood. Importantly, acknowledging brain abnormalities due to poverty in early childhood can help increase economic equity. In the current study, we provide a comprehensive list of future studies to help understand the impact of poverty on the brain.

Household Air Pollution Interventions to Improve Health in Low- and Middle-Income Countries: An Official American Thoracic Society Research Statement

Background: An estimated 3 billion people, largely in low- and middle-income countries, rely on unclean fuels for cooking, heating, and lighting to meet household energy needs. The resulting exposure to household air pollution (HAP) is a leading cause of pneumonia, chronic lung disease, and other adverse health effects. In the last decade, randomized controlled trials of clean cooking interventions to reduce HAP have been conducted. We aim to provide guidance on how to interpret the findings of these trials and how they should inform policy makers and practitioners.Methods: We assembled a multidisciplinary working group of international researchers, public health practitioners, and policymakers with expertise in household air pollution from within academia, the American Thoracic Society, funders, nongovernmental organizations, and global organizations, including the World Bank and the World Health Organization. We performed a literature search, convened four sessions via web conference, and developed consensus conclusions and recommendations via the Delphi method.Results: The committee reached consensus on 14 conclusions and recommendations. Although some trials using cleaner-burning biomass stoves or cleaner-cooking fuels have reduced HAP exposure, the committee was divided (with 55% saying no and 45% saying yes) on whether the studied interventions improved measured health outcomes.Conclusions: HAP is associated with adverse health effects in observational studies. However, it remains unclear which household energy interventions reduce exposure, improve health, can be scaled, and are sustainable. Researchers should engage with policy makers and practitioners working to scale cleaner energy solutions to understand and address their information needs.

Navigating the economic challenges in childhood cancer control in low- and middle-income countries: Insights from the CC-BRIDGE tool and the global initiative for childhood cancer

The increasing incidence of childhood cancer in low- and middle-income countries (LMICs) presents significant economic and logistical challenges, affecting health care provision and equitable treatment access. This editorial explores the economic barriers to pediatric oncology care in LMICs, highlighting resource scarcity, socioeconomic inequities, and health care complexities. It emphasizes the need for detailed cost analysis within health systems complicated by inadequate data and variable treatment protocols. Central to the discussion is the "Childhood Cancers Budgeting Rapidly to Incorporate Disadvantaged Groups for Equity (CC-BRIDGE) Tool" from the manuscript by Nancy Bolous et al., who proposed an innovative method to estimate the cost of integrating childhood cancer services into National Cancer Control Plans. This tool aligns with the World Health Organization's Global Initiative for Childhood Cancer to enhance survival rates and advocate for universal health coverage in pediatric oncology. The CC-BRIDGE tool's methodological rigor provides a structured framework for cost analysis. Yet, it is recognized as an initial step requiring further enhancements for comprehensive economic forecasting and societal cost assessments. In conclusion, the editorial highlights the tool's critical role in incorporating childhood cancer care into national strategies in LMICs, contributing to the broader fight against cancer and advocating for comprehensive, equitable health care. It signifies a vital stride toward addressing pediatric oncology's economic challenges and supporting universal health coverage for childhood cancer care.

Optimizing Clinical Implementation of Hypofractionation: Comprehensive Evidence Synthesis and Practical Guidelines for Low- and Middle-Income Settings

The global cancer burden, especially in low- and middle-income countries (LMICs), worsens existing disparities, amplified by the rising costs of advanced treatments. The shortage of radiation therapy (RT) services is a significant issue in LMICs. Extended conventional treatment regimens pose significant challenges, especially in resource-limited settings. Hypofractionated radiotherapy (HRT) and ultra-hypofractionated/stereotactic body radiation therapy (SBRT) offer promising alternatives by shortening treatment durations. This approach optimizes the utilization of radiotherapy machines, making them more effective in meeting the growing demand for cancer care. Adopting HRT/SBRT holds significant potential, especially in LMICs. This review provides the latest clinical evidence and guideline recommendations for the application of HRT/SBRT in the treatment of breast, prostate, and lung cancers. It emphasizes the critical importance of rigorous training, technology, stringent quality assurance, and safety protocols to ensure precise and secure treatments. Additionally, it addresses practical considerations for implementing these treatments in LMICs, highlighting the need for comprehensive support and collaboration to enhance patient access to advanced cancer care.

Perceptions of Suicide among Pakistanis: Results of an Online Survey

OBJECTIVE

In Pakistan, a predominantly Muslim country, information on the patterning of suicidal thoughts and behaviors, as well as associated public perceptions and opinions, is limited. We sought to advance knowledge on suicide and self-harm in Pakistan with a large, online survey.

METHOD

Leveraging results from a twelve-item online survey (N = 5,157) circulated by the largest English language newspaper in Pakistan, we assessed personal experiences, opinions, and attitudes toward help-seeking in the context of suicide. We calculated proportions with 95% confidence intervals for endorsed responses and implemented binomial generalized linear models with odds ratios to assess differing response tendencies by age, gender, and urban/rural residence.

RESULTS

Personal experiences related to suicide and self-harm as well as encounters in social circles were common. Mental illness tended to be recognized as a high likelihood contributor to suicide death over and above nonviolent interpersonal problems. Most considered suicide a way to escape pain, and few considered suicide to be immoral. Barriers to help-seeking included social deterrents, inaccessibility, and unaffordability. Women and youth emerged as higher risk groups, though the status of rural Pakistanis remained unclear.

CONCLUSION

The survey provides a preliminary basis for considering the unique experiences and perspectives of the public in shaping suicide prevention and intervention efforts in Pakistan.

Research Review: Psychological and psychosocial interventions for children and adolescents with depression, anxiety, and post-traumatic stress disorder in low- and middle-income countries - a systematic review and meta-analysis

BACKGROUND

The incidence of depression, anxiety, and post-traumatic stress disorder (PTSD) among children and adolescents residing in low- and middle-income countries (LMICs) poses a significant public health concern. However, there is variation in the evidence of effective psychological interventions. This meta-analysis aims to provide a complete overview of the current body of evidence in this rapidly evolving field.

METHODS

We conducted searches on PubMed, Embase.com, and EBSCO/APA PsycInfo databases up to June 23, 2022, identify randomized controlled trials (RCTs) investigating the effectiveness of psychological interventions in LMICs that targeted children and adolescents with elevated symptoms above a cut-off score for depression, anxiety, and PTSD, comparing a psychological or psychosocial intervention with other control conditions. We conducted random effects meta-analyses for depression, anxiety, and PTSD symptoms. Sensitivity analysis for outliers and high-risk studies, and analyses for the publication bias were carried out. Subgroup analyses investigated how the intervention type, intervention format, the facilitator, study design, and age group of the participant predicted effect sizes.

RESULTS

Thirty-one RCTs (6,123 participants) were included. We found a moderate effect of interventions on depression outcomes compared to the control conditions (g = 0.53; 95% CI: 0.06-0.99; NNT = 6.09) with a broad prediction interval (PI) (-1.8 to 2.86). We found a moderate to large effect for interventions on anxiety outcomes (g = 0.88; 95% CI: -0.03 to 1.79; NNT = 3.32) with a broad PI (-3.14 to 4.9). Additionally, a moderate effect was observed on PTSD outcomes (g = 0.54; 95% CI: 0.19-0.9; NNT = 5.86) with a broad PI (-0.64 to 1.72).

CONCLUSIONS

Psychological and psychosocial interventions aimed at addressing depression, anxiety, and PTSD among children and adolescents in LMICs have demonstrated promising results. However, future studies should consider the variation in evidence and incorporate long-term outcomes to better understand the effectiveness of these interventions.

A scoping review considering the processes involved in changing abortion laws in low- and middle-income countries

Providing legal and safe abortion is promoted as one of the key global strategies for reducing maternal mortality. Following the landmark 1994 International Conference on Population and Development, low- and middle-income countries (LMICs) are shifting towards more liberal abortion legislation. Whilst the existing literature has predominantly focused on agenda setting and individual country contexts, there is a need to understand the universal policy process of changing abortion laws. Drawing on the heuristic policy stages model and policy analysis triangle, this paper explores the processes involved in changing abortion laws in LMICs and discusses the influencing factors. We conducted a search for peer-reviewed literature in ProQuest, Scopus, Global Health (Ovid), PubMed and CINAHL. Initially, the search was conducted in February 2021 and was then re-run in May 2023. A total of 25 studies were included in the analysis. Following a descriptive, thematic and interpretive analysis of the extracted data, we have drawn out the key stages involved in changing abortion laws in LMICs: (1) establishing the need for changing abortion laws in a local context; (2) generating local evidence to support changes in abortion laws; (3) drafting of new and/or amendments of existing abortion laws; (4) adoption and enactment of changes in abortion laws; (5) translating the legal provisions into services and (6) assessing the impact of changes in abortion laws on maternal health. Our analysis explores the influence of actors and contextual factors, and we also discuss the policy solutions and decisions made by governments. The findings demonstrate that while the timing of change in abortion law was found to be dependent on the context of individual settings, the process and factors that influenced the change were remarkably consistent across geographies. Further research is required to evaluate the link between changes in abortion laws and maternal health outcomes.

Developing an infection prevention and control intervention to reduce hospital-acquired infections in Cambodia and Lao People's Democratic Republic: the HAI-PC study protocol

Background

Hospital-acquired infections (HAIs) are significant public health issues, especially in low-and middle-income countries (LMICs). Hand hygiene and low-level disinfection of equipment practices among healthcare workers are some of the essential measures to reduce HAIs. Various infection prevention and control (IPC) interventions to reduce HAI incidence have been developed. However, effective interventions have not been well developed in the LMICs context. Therefore, this protocol aims to develop, pilot, and assess the feasibility and acceptability of an IPC intervention in Cambodia and the Lao People's Democratic Republic.

Methods

This study will consist of four phases guided by the Medical Research Council (MRC) Framework. Three hospitals will be purposely selected - each from the district, provincial, and national levels - in each country. The gap analysis will be conducted in Phase 1 to explore IPC practices among healthcare workers at each hospital through desk reviews, direct observation of hand hygiene and low-level disinfection of equipment practices, in-depth interviews with healthcare workers, and key informant interviews with stakeholders. In Phase 2, an IPC intervention will be developed based on the results of Phase 1 and interventions selected from a systematic literature review of IPC interventions in LMICs. In Phase 3, the developed intervention will be piloted in the hospitals chosen in Phase 1. In Phase 4, the feasibility and acceptability of the developed intervention will be assessed among healthcare workers and representatives at the selected hospitals. National consultative workshops in both countries will be conducted to validate the developed intervention with the national technical working groups.

Discussion

The MRC Framework will be employed to develop and evaluate an intervention to reduce HAIs in two LMICs. This theoretical framework will be used to explore the factors influencing hand hygiene compliance among healthcare workers. The gap analysis results will allow us to develop a comprehensive IPC intervention to reduce HAI incidence in Cambodia and Lao People's Democratic Republic. Findings from this protocol will feed into promising IPC interventions to reduce HAI incidence in other resource-limited settings.

The long-term impact and value of curative therapy for HIV: a modelling analysis

INTRODUCTION

Curative therapies (CTx) to achieve durable remission of HIV disease without the need for antiretroviral therapy (ART) are currently being explored. Our objective was to model the long-term health and cost outcomes of HIV in various countries, the impact of future CTx on those outcomes and the country-specific value-based prices (VBPs) of CTx.

METHODS

We developed a decision-analytic model to estimate the future health economic impacts of a hypothetical CTx for HIV in countries with pre-existing access to ART (CTx+ART), compared to ART alone. We modelled populations in seven low-and-middle-income countries and five high-income countries, accounting for localized ART and other HIV-related costs, and calibrating variables for HIV epidemiology and ART uptake to reproduce historical HIV outcomes before projecting future outcomes to year 2100. Health was quantified using disability-adjusted life-years (DALYs). Base case, pessimistic and optimistic scenarios were modelled for CTx+ART and ART alone. Based on long-term outcomes and each country's estimated health opportunity cost, we calculated the country-specific VBP of CTx.

RESULTS

The introduction of a hypothetical CTx lowered HIV prevalence and prevented future infections over time, which increased life-years, reduced the number of individuals on ART, reduced AIDS-related deaths, and ultimately led to fewer DALYs versus ART-alone. Our base case estimates for the VBP of CTx ranged from $5400 (Kenya) up to $812,300 (United States). Within each country, the VBP was driven to be greater primarily by lower ART coverage, lower HIV incidence and prevalence, and higher CTx cure probability. The VBP estimates were found to be greater in countries where HIV prevalence was higher, ART coverage was lower and the health opportunity cost was greater.

CONCLUSIONS

Our results quantify the VBP for future curative CTx that may apply in different countries and under different circumstances. With greater CTx cure probability, durability and scale up, CTx commands a higher VBP, while improvements in ART coverage may mitigate its value. Our framework can be utilized for estimating this cost given a wide range of scenarios related to the attributes of a given CTx as well as various parameters of the HIV epidemic within a given country.

Patient perspectives on the helpfulness of a community health worker program for HIV care engagement in Tanzania

Task-shifting is a valuable approach for redistributing clinical tasks to nonprofessional health workers and relieving human resource shortages. The Community-Based HIV Services (CBHS) program is a national cohort of volunteer community health workers (CHWs) who support HIV care engagement at clinics in Tanzania. We recruited 23 patients initiating HIV care at two clinics to understand their experiences with the CBHS program. Participants completed qualitative interviews by telephone discussing the perceived helpfulness of the program, their level of connection with CHWs, and suggestions for improvement. Data were analyzed through an inductive, team-based qualitative approach. Most participants found the program to be helpful and described close, positive connections. CHWs offered education, emotional support to accept one's diagnosis and cope with stigma, and encouragement to remain engaged in HIV care. However, several participants described minimal, shallow contact with CHWs, and felt the program did not benefit their HIV care. Participants recommended increasing CHW efforts to engage people living with HIV (PLWH) in the broader community, and addressing socioeconomic barriers to care engagement. When contacts are consistent, the CBHS program is a strong resource for PLWH. To maximize the potential of the program, administrators should enhance oversight and extend new training opportunities for CHWs.

A qualitative investigation of the psychosocial services utilised by care-givers of patients with Alzheimer's disease and related dementias in southwestern Uganda

Individuals with Alzheimer's disease and related dementias often require substantial support from other people. Much of the care-giving is from family members who eventually experience physical, emotional and financial stress, depression and fatigue. In Uganda, families are a cornerstone in providing care to individuals with dementia. However, little is known about the psychosocial supports available to the care-givers in their care-giving role. We assessed the psychosocial supports available to care-givers of individuals with Alzheimer's disease and related dementias in southwestern Uganda. We conducted 34 in-depth interviews at three referral hospitals at which care-givers identified by the treating clinicians were approached for informed consent. The interviews were conducted until thematic saturation was reached, and the interviews were translated and transcribed. Thematic content analysis was used to analyse the data. Care-giver supports were structured into two major themes: medical supports utilized and supports beyond the medical care system. Medical supports highlighted information provided by medical professionals. Supports beyond the medical care system included emotional and instrumental supports provided by religious leaders, the local communities and family members. Care-givers for individuals with dementia in southwestern Uganda receive educational support from medical practitioners, and unstructured emotional and instrumental supports from the family and community.

Four years after the implementation of antimicrobial stewardship program in Jordan: evaluation of program's core elements

Objectives

To combat antimicrobial resistance, the World Health Organization (WHO) urged healthcare organizations in Low- and Middle-Income Countries (LMICs) to implement the core elements of the antimicrobial stewardship (AMS) programs. In response, Jordan took action and developed a national antimicrobial resistance action plan (NAP) in 2017 and commenced the AMS program in all healthcare facilities. It is paramount to evaluate the efforts to implement the AMS programs and understand the challenges of implementing a sustainable and effective program, in Low-Middle Income Country (LMIC) contexts. Therefore, the aim of this study was to appraise the compliance of public hospitals in Jordan to the WHO core elements of effective AMS programs after 4 years of commencement.

Methods

A cross-sectional study in public hospitals in Jordan, using the WHO AMS program core elements for LMICs was carried out. The questionnaire comprised 30 questions that covered the program's six core elements: leadership commitment, accountability and responsibility, AMS actions, education and training, monitoring, and evaluation, and reporting and feedback. A five-point Likert scale was employed for each question.

Results

A total of 27 public hospitals participated, with a response rate of 84.4%. Adherence to core elements ranged from (53%) in the leadership commitment domain to (72%) for AMS procedure application (actions). Based on the mean score, there was no significant difference between hospitals according to location, size, and specialty. The most neglected core elements that emerged as top priority areas were the provision of financial support, collaboration, access, as well as monitoring and evaluation.

Conclusion

The current results revealed significant shortcomings in the AMS program in public hospitals despite 4 years of implementation and policy support. Most of the core elements of the AMS program were below average, which requires hospital leadership commitment, and multifaceted collaborative actions from the concerned stakeholders in Jordan.

Using an Antibiogram Profile to Improve Infection Control and Rational Antimicrobial Therapy in an Urban Hospital in The Gambia, Strategies and Lessons for Low- and Middle-Income Countries

Antimicrobial resistance is a global health threat and efforts to mitigate it is warranted, thus the need for local antibiograms to improve stewardship. This study highlights the process that was used to develop an antibiogram to monitor resistance at a secondary-level health facility to aid empirical clinical decision making in a sub-Saharan African county. This retrospective cross-sectional descriptive study used 3 years of cumulative data from January 2016 to December 2018. Phenotypic data was manually imputed into WHONET and the cumulative antibiogram constructed using standardized methodologies according to CLSI M39-A4 guidelines. Pathogens were identified by standard manual microbiological methods and antimicrobial susceptibility testing was performed using Kirby-Bauer disc diffusion method according to CLSI M100 guidelines. A total of 14,776 non-duplicate samples were processed of which 1163 (7.9%) were positive for clinically significant pathogens. Among the 1163 pathogens, E. coli (n = 315) S. aureus (n = 232), and K. pneumoniae (n = 96) were the leading cause of disease. Overall, the susceptibility for E. coli and K. pneumoniae from all samples were: trimethoprim-sulfamethoxazole (17% and 28%), tetracycline (26% and 33%), gentamicin (72% and 46%), chloramphenicol (76 and 60%), and ciprofloxacin (69% and 59%), and amoxicillin/clavulanic (77% and 54%) respectively. Extended spectrum beta-lactamase (ESBL) resistance was present in 23% (71/315) vs. 35% (34/96) respectively. S. aureus susceptibility for methicillin was 99%. This antibiogram has shown that improvement in combination therapy is warranted in The Gambia.

Technical Perspective for Video Based Assessment of Surgeries in Low-Resource Settings

OBJECTIVE

Scalable digital learning environments are essential to sustain surgical training programs worldwide. Detailed images of surgeries enriched with educational annotations are vital to train the eyes of the learners. Here, we report a low-cost method, deployed in a low-resource setting in West Africa, which may contribute to the growth of use in open-sourced digital surgical resources world-wide.

DESIGN

This paper is based on the authors participatory and observational experiences creating surgical video content by way of recording surgical procedures and reflecting on field notes and video content. All surgeries were recorded between January and December 2018.

SETTING

Masanga Hospital, a rural district hospital in Sierra Leone, West Africa.

PARTICIPANTS

Thirty-five patients undergoing inguinal hernia repair, elective caesarian section, salpingectomy, bowel resection, hydrocele repair, or below-knee amputation consented for recording their surgical procedure and using the anonymized material for educational purposes.

RESULTS

This manual for non-professional cinematographers provides chronological steps for shooting a surgical procedure in a low-resource setting. Recording a surgical procedure to explain surgical techniques, and perform quality assessment through error analysis and coaching requires more than just point-and-shoot. While taking into account local customs and possibilities, practical tips were provided to prepare for the set-up, and recording of a surgical procedure in a low-resourced setting.

CONCLUSION

Commercially available digital video technology allows for filming high-quality surgical procedures for educational purposes at rural district hospitals in a low-resource setting.

Utilization of telehealth to manage the Covid-19 pandemic in low- and middle-income countries: a scoping review

OBJECTIVE

Recently, the coronavirus disease 2019 (Covid-19) pandemic has led to an increase in the use of telehealth technology. It seems that the application of this technology in low- and middle-income countries (LMICs) has been limited, and few studies have been undertaken to review the current state of knowledge in this area. The aim of the present study was to explore the utilization of telehealth to manage the Covid-19 pandemic in LMICs.

MATERIALS AND METHODS

This scoping review was conducted in 2022. PubMed, Web of Science, Scopus, the Cochrane Library, IEEE Xplore, and ProQuest were searched, and all quantitative research, qualitative studies, case reports, and case studies related to the use of telehealth to manage Covid-19 in LMICs and published since 2020 were included in the study. The findings were analyzed and reported narratively.

RESULTS

In total, 18 articles were included in the research. These studies were conducted in South Asia, sub-Saharan Africa, the Middle East and North Africa, and East Asia and Oceania. Telehealth interventions included teleconsultation, telecoaching, teledermatology, televisit, mhealth applications, telerehabilitation, telepharmacy, and telepsychiatry. WhatsApp was the most common way for service delivery and in most studies, patients and health care providers were satisfied with services.

CONCLUSION

Although the use of telehealth interventions was limited in LMICs during the Covid-19 pandemic, in most cases, it was an effective solution to combat the outbreak of Covid-19 and had positive outcomes. A comparison between the characteristics and clinical effectiveness of similar interventions in different countries including LMICs are worth investigation in the future studies.

Sociodemographic, economic, physical, and mental health status of previously hospitalised patients with COVID-19 symptoms in Bangladesh: Protocol for a mixed-method study

Introduction

Not much is known about the long-term consequences of COVID-19, popularly known as long COVID. This is particularly so in terms of patterns and clusters of symptoms over time, sociodemographic and economic characteristics of patients, and related clinical history. This is crucial for resource-constrained health systems such as Bangladesh to address long COVID as a forthcoming challenge. This protocol aims to investigate the consequences of COVID-19 over time for physical and mental health and how these are associated with demographic and socio-economic factors.

Methods and analysis

This mixed-method study collected information on all patients with symptoms of COVID-19 admitted to and discharged after recovery from a COVID-19-dedicated hospital in Bangladesh (N = 942), from April to December 2020. The sources of data were admission records and discharge certificates from the hospital for clinical history, cross-sectional survey on physical and mental health (assessed by DASS21 scale)-related symptoms and socioeconomic changes after recovery, and qualitative in-depth interviews on experiences of COVID-19. Interviews were conducted over the phone. Quantitative analysis was done to estimate the prevalence of physical and mental health consequences of COVID-19 after recovery and the association with socio-economic and demographic information. The qualitative analysis was performed using a thematic analysis approach.

Discussion

It is imperative to understand the post-COVID consequences and related health and non-health aspects to inform evidence-based policymaking, especially for resource-poor contexts such as Bangladesh. Given the dearth of evidence in this regard, the proposed study will contribute to bridging this knowledge gap. It is important to note that this study is one of the few which presents information on post-COVID-19 consequences in the context of low- and middle-income countries and the first in Bangladesh.

An Innovative Method for BTEX Emission Inventory and Development of Mitigation Measures in Developing Countries-A Case Study: Ho Chi Minh City, Vietnam

Benzene, toluene, ethylbenzene, and xylenes (BTEX) are carcinogenic pollutants. However, the average concentration in 1 h of some pollutants belonging to BTEX, such as benzene, in Ho Chi Minh City (HCMC) is higher than the national standard QCVN 06:2009/BTNMT by about ten times. This research is the first to calculate the emission of BTEX for developing countries on a city scale. This paper developed a method to calculate cold emission factors based on hot emission factors for BTEX. Five spreadsheets developed and calculated these cold emission factors for five vehicle categories. A comprehensive emission inventory (EI) for BTEX was conducted in HCMC to determine the cause of BTEX pollution. An innovative methodology with bottom-up and top-down combination was applied to conduct BTEX EI, in which the EMISENS model was utilized to generate the EI for road traffic sources, and the emission factors method was utilized for other emission sources. Among emission reasons, motorcycles contribute the highest to HCMC air pollution, responsible for 93%, 90%, 98.9%, and 91.5% of benzene, toluene, ethylbenzene, and xylene, respectively. Cars contributed 5%, 6%, 0.8%, and 6.5% of benzene, toluene, ethylbenzene, and xylene, respectively. For LDVs, the emission from benzene, toluene, ethylbenzene, and xylene accounted for 1%, 2%, 0.2%, and 1.9%. The major reasons for point sources were metal production, which had 1%, 2%, and 0.1% for benzene, toluene, ethylbenzene, and xylenes emissions. The area source had a minority emission of total BTEX in Ho Chi Minh City. Our findings can be used to invest in the most significant sources to reduce BTEX in HCMC. Our approach can be applied in similar urban areas in BTEX EI. This research also developed nine measures to reduce BTEX in HCMC for human health protection.

Perceptions of the use of mobile phones to access reproductive health care services in Tamale, Ghana

Introduction

Africa has one of the world's highest populations of young people. In addition, Africa has one of the highest proportions of young people facing the worst health challenges. Although previous scholars have reported that young people were using mobile phones to fill in the gaps in accessing reproductive health services, among other health services, there was little comprehensive research on the perception of young people in Tamale, Ghana, on the use of mobile phones to access reproductive health services. This study analyzed the perceptions on mobile phone use to access reproductive health services among young people in Tamale, Ghana.

Methods

The research used a quantitative method design from a target population of 72,706 young people from selected peri-urban, low-income, middle income and high-income residential areas in Tamale Metropolis, Ghana. The sample size used was 397 young people. Participants were selected using a stratified multistage sampling strategy. Descriptive statistics were used to analyse the data.

Results

A total of 86% of the respondents agree that the use of mobile phones helps to overcome cultural challenges that young people in Tamale encounter in accessing reproductive health care. Also, 84.6% of the respondents agree that the use of mobile phones helps them to overcome inadequate access to reproductive health information and services. The use of mobile phones helps to overcome the negative attitude of health providers toward young people in need of reproductive health services was agreed by most of the respondents [strongly agree (35.4%) and agree (49.4%)].

Conclusion

This study informed highly positive perceptions and attitudes toward the use of mobile phones to access Reproductive Health Services in Tamale, Ghana. There is, therefore the need for the health sector to reform its mode of prescriptions of medication, consultation, and service delivery to leverage on the advantages that mHealth presents.

Potential productivity loss from uncorrected and under-corrected presbyopia in low- and middle-income countries: A life table modeling study

Objective

To estimate the burden of potential productivity losses due to uncorrected and under-corrected presbyopia in LMICs among the working-age population in both the cross-sectional and longitudinal manner.

Methods

We extracted data for the prevalence of presbyopia from the Global Burden of Diseases (GBD), Injuries, and Risk Factors Study 2019. Data for the gross domestic product (GDP) per capita were extracted from the World Bank database and Central Intelligence Agency's World Factbook. We introduced life table models to construct age cohorts (in 5-year age groups) of the working-age population (aged from 40 to 64 years old) in LMICs, with simulated follow-up until 65 years old in people with and without uncorrected presbyopia. The differences in productivity-adjusted life years (PALYs) lived and productivity between these two cohorts were calculated. The potential productivity loss was estimated based on GDP per capita. The WHO standard 3% annual discount rate was applied to all years of life and PALYs lived.

Results

In 2019, there were 238.40 million (95% confidence interval [CI]: 150.92-346.78 million) uncorrected and under-corrected presbyopia cases in LMICs, resulting in 54.13 billion (current US dollars) (95% confidence interval [CI]: 34.34-79.02 billion) potential productivity losses. With simulated follow-up until retirement, those with uncorrected and under-corrected presbyopia were predicted to experience an additional loss of 155 million PALYs (an average loss of 0.7 PALYs per case), which was equivalent to a total loss of US$ 315 billion (an average loss of US$ 1453.72 per person).

Conclusions

Our findings highlight the considerable productivity losses due to uncorrected and under-corrected presbyopia in LMICs, especially in a longitudinal manner. There is a great need for the development of enabling eye care policies and programs to create access to eye care services, and more healthcare investment in the correction of presbyopia in the working-age population in LMICs. This study could provide evidences for some potential health-related strategies for socio-economic development.

Management of fracture-related infection in low resource settings: how applicable are the current consensus guidelines?

The global burden of fracture-related infection (FRI) is likely to be found in countries with limited healthcare resources and strategies are needed to ensure the best available practice is context appropriate. This study has two main aims: (i) to assess the applicability of recently published expert guidance from the FRI consensus groups on the diagnosis and management of FRI to low- and middle-income countries (LMICs); (ii) to summarise the available evidence on FRI, with consideration for strategies applicable to low resource settings.

Data related to the International Consensus Meeting Orthopaedic Trauma Work Group and the International Fracture Related Infection Consensus Group FRI guidelines were collected including panel membership, country of origin, language of publication, open access status and impact factor of the journal of publication. The recommendations and guidelines were then summarised with specific consideration for relevance and applicability to LMICs. Barriers to implementation were explored within a group of LMIC residents and experienced workers.

The authorship, evidence base and reach of the FRI consensus guidelines lack representation from low resource settings. The majority of authors (78.5–100%) are based in high-income countries and there are no low-income country collaborators listed in any of the papers. All papers are in English.

The FRI consensus guidelines give a clear set of principles for the optimum management of FRI. Many of these – including the approach to diagnosis, multidisciplinary team working and some elements of surgical management – are achievable in low resource settings. Current evidence suggests that it is important that a core set of principles is prioritised but robust evidence for this is lacking. There are major organisational and infrastructure obstacles in LMICs that will make any standardisation of FRI diagnosis or management challenging. The detail of how FRI consensus principles should be applied in low resource settings requires further work.

The important work presented in the current FRI consensus guidelines is relevant to low resource settings. However, leadership, collaboration, creativity and innovation will be needed to implement these strategies for communities who need it the most.

Does Digital Literacy Empower Adolescent Girls in Low- and Middle-Income Countries: A Systematic Review

Background: The vast majority (90%) of the world's adolescents aged 10–19 live in low- and middle-income countries (LMICs); and in those resource-limited settings, girls face distinct challenges across multiple health, social, and economic domains. Gender equality and girls' empowerment are key goals in their own right and are central to all other development goals. Digital literacy is a great enabler for the empowerment of young girls. This systematic review aims to assess the range and nature of digital literacy interventions implemented to empower adolescent girls in LMICs and identify evidence about adolescent girls' access and use of digital technologies in LMICs.

Methods: We conducted a systematic review of studies following Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) standards for systematic reviews. Two reviewers selected studies, conducted quality assessments, and extracted data by using standard forms. The collected data include the design of the study, type of digital literacy intervention, target audience, intervention received, intervention reach, data analysis, and study outcomes. The review is registered with PROSPERO (CRD42020216756).

Results: Thirty-five studies met the eligibility for inclusion and of those, 11 were experimental studies (randomized controlled trial = 6; quasi-experimental = 2; before-after with no control = 3), 11 were cross-sectional/descriptive studies, seven studies used a mixed-method approach, and six were qualitative studies on digital literacy interventions to empower young girls in LMICs. The majority of digital literacy interventions were designed and implemented to improve sexual and reproductive health rights and decision-making of adolescent girls in LMICs (n = 33). Only three papers reported the use of digital media for health-related information and decision making, while only one reported on educational and social empowerment.

Discussion: Our findings suggest that digital literacy interventions such as mobile phones, mobile health tools, media exposure, access to the internet, internet-based educational strategies, social media exposure are effective to empower adolescent girls to access health services and information and also enhance the access to educational resources. However, we found inconclusive evidence on the effectiveness of digital literacy to enhance girls' access to financial services and economic empowerment. More rigorous studies with long-term follow-ups to assess the effectiveness of such interventions to empower adolescent girls in LMICs are urgently needed.

Implementation of Best-Evidence Osteoarthritis Care: Perspectives on Challenges for, and Opportunities From, Low and Middle-Income Countries

The "Joint Effort Initiative" (JEI) is an international consortium of clinicians, researchers, and consumers under the auspices of the Osteoarthritis Research Society International (OARSI). The JEI was formed with a vision to improve the implementation of coordinated programs of best evidence osteoarthritis care globally. To better understand some of the issues around osteoarthritis care in low- and middle-income countries (LMICs), the JEI invited clinician researcher representatives from South Africa, Brazil, and Nepal to discuss their perspectives on challenges and opportunities to implementing best-evidence osteoarthritis care at the OARSI World Pre-Congress Workshop. We summarize and discuss the main themes of the presentations in this paper. The challenges to implementing evidence-based osteoarthritis care identified in LMICs include health inequities, unaffordability of osteoarthritis management and the failure to recognize osteoarthritis as an important disease. Fragmented healthcare services and a lack of health professional knowledge and skills are also important factors affecting osteoarthritis care in LMICs. We discuss considerations for developing strategies to improve osteoarthritis care in LMICs. Existing opportunities may be leveraged to facilitate the implementation of best-evidence osteoarthritis care. We also discuss strategies to support the implementation, such as the provision of high-quality healthcare professional and consumer education, and systemic healthcare reforms.

A Systematic Review of Interventions That Integrate Perinatal Mental Health Care Into Routine Maternal Care in Low- and Middle-Income Countries

BACKGROUND

Women in low- and middle-income countries (LMICs) are disproportionally affected by perinatal depression and anxiety and lack access to mental health care. Integrating perinatal mental health care into routine maternal care is recommended to address gaps in access to mental health care in such under-resourced settings. Understanding the effectiveness of interventions that integrate perinatal mental health care into routine maternal care in LMICs is critical to inform ongoing intervention development, implementation, and scale-up. This systematic review aims to assess the effectiveness of interventions that integrate perinatal mental health care into routine maternal care to improve maternal mental health and infant health outcomes in LMICs.

METHOD

In accordance with the PRISMA guidelines, an electronic database search was conducted seeking publications of controlled trials examining interventions that aimed to integrate perinatal mental health care into routine maternal care in LMICs. Abstracts and full text articles were independently reviewed by two authors for inclusion utilizing Covidence Review Software. Data was extracted and narrative synthesis was conducted.

FINDINGS

Twenty studies met eligibility criteria from the initial search results of 2,382 unique citations. There was substantial heterogeneity between the study samples, intervention designs, and outcome assessments. Less than half of the studies focused on women with active depression or anxiety. Most studies (85%) implemented single intervention designs involving psychological, psychosocial, psychoeducational, or adjuvant emotion/stress management. There were few interventions utilizing multicomponent approaches, pharmacotherapy, or referral to mental health specialists. Outcome measures and assessment timing were highly variable. Eighteen studies demonstrated significantly greater improvement on depression and/or anxiety measures in the intervention group(s) as compared to control.

CONCLUSION

Integrated interventions can be effective in LMICs. The findings provide a critical understanding of current interventions design gaps. This includes the lack of comprehensive intervention designs that incorporate increasing intensity of treatment for more severe illness, pharmacotherapy, mental health specialist referrals, and non-mental health professional training and supervision. The findings also provide strategies to overcome design and implementation barriers in LMICs. Study findings provide a foundation for future evidence-based adaptation, implementation, and scale-up of interventions that integrate perinatal mental health care into routine maternal care in LMICs.

Implementation of Fingerprint Technology for Unique Patient Matching and Identification at an HIV Care and Treatment Facility in Western Kenya: Cross-sectional Study

Background

Unique patient identification remains a challenge in many health care settings in low- and middle-income countries (LMICs). Without national-level unique identifiers for whole populations, countries rely on demographic-based approaches that have proven suboptimal. Affordable biometrics-based approaches, implemented with consideration of contextual ethical, legal, and social implications, have the potential to address this challenge and improve patient safety and reporting accuracy. However, limited studies exist to evaluate the actual performance of biometric approaches and perceptions of these systems in LMICs.

Objective

The aim of this study is to evaluate the performance and acceptability of fingerprint technology for unique patient matching and identification in the LMIC setting of Kenya.

Methods

In this cross-sectional study conducted at an HIV care and treatment facility in Western Kenya, an open source fingerprint application was integrated within an implementation of the Open Medical Record System, an open source electronic medical record system (EMRS) that is nationally endorsed and deployed for HIV care in Kenya and in more than 40 other countries; hence, it has potential to translate the findings across multiple countries. Participants aged >18 years were conveniently sampled and enrolled into the study. Participants’ left thumbprints were captured and later used to retrieve and match records. The technology’s performance was evaluated using standard measures: sensitivity, false acceptance rate, false rejection rate, and failure to enroll rate. The Wald test was used to compare the accuracy of the technology with the probabilistic patient-matching technique of the EMRS. Time to retrieval and matching of records were compared using the independent samples 2-tailed t test. A survey was administered to evaluate patient acceptance and satisfaction with use of the technology.

Results

In all, 300 participants were enrolled; their mean age was 36.3 (SD 12.2) years, and 58% (174/300) were women. The relevant values for the technology’s performance were sensitivity 89.3%, false acceptance rate 0%, false rejection rate 11%, and failure to enroll rate 2.3%. The technology’s mean record retrieval speed was 3.2 (SD 1.1) seconds versus 9.5 (SD 1.9) seconds with demographic-based record retrieval in the EMRS (P<.001). The survey results revealed that 96.3% (289/300) of the participants were comfortable with the technology and 90.3% (271/300) were willing to use it. Participants who had previously used fingerprint biometric systems for identification were estimated to have more than thrice increased odds of accepting the technology (odds ratio 3.57, 95% CI 1.0-11.92).

Conclusions

Fingerprint technology performed very well in identifying adult patients in an LMIC setting. Patients reported a high level of satisfaction and acceptance. Serious considerations need to be given to the use of fingerprint technology for patient identification in LMICs, but this has to be done with strong consideration of ethical, legal, and social implications as well as security issues.

Improved documentation following the implementation of a trauma registry: A means of sustainability for trauma registries in low- and middle-income countries

INTRODUCTION

Trauma registries in low- and middle-income countries (LMICs) are critical for improving trauma care; however, while some registries have been established in low-income settings, few are sustained due to a lack of sustainable funding. In many LMIC institutions, funding is dependent on documentation of trauma patients, but patient records may be of poor quality, missing, or incomplete. The development of a trauma registry and electronic patient registration system could be used to improve documentation of trauma patients in a low-income setting and lead to increased funding for trauma care.

METHODS

A retrospective chart review of trauma patients at Mbarara Regional Referral Hospital in Uganda was performed, documenting the monthly admissions from January 2015-July 2016 prior to the establishment of a trauma registry. A trauma registry and electronic patient registration system were established in 2017, and monthly admissions from February 2017-December 2019 were documented. A negative binomial regression analysis was performed comparing the incident rate of admission pre-implementation of the registry compared to post-implementation, adjusting for month and year. Completeness of trauma patient records was also assessed.

RESULTS

Prior to the implementation of the trauma registry and patient registration system (2015-2016), there was a mean of 5.2 (SD 4.4) trauma records per month identified. Following the implementation of the trauma registry, a mean of 103.4 trauma records per month were documented (SD 32.0) for an increased incident rate ratio of 20.9 (95% CI 15.7-27.6, p<0.001). There was also a significant increase in percentage of documents completed (OR 49.1, CI 12.4-193.7, p<0.001).

DISCUSSION

Following the implementation of a trauma registry and electronic patient registration system at this low-income country hospital, an increase of 20.9 times completed trauma patient documentation was identified, and completion of the records improved. This more accurate documentation could be used to apply for increased government funding for trauma patients and sustain the trauma registry in the long term and could represent a means of long-term sustainability for other trauma registries in LMICs.

Assessing the Influence of Community Health Worker Support on Early Antiretroviral Therapy Adherence, Anticipated Stigma, and Mental Health Among People Living with HIV in Tanzania

In many low- and middle-income countries, community health workers (CHWs) support multiple aspects of HIV care, including patient education and counseling, adherence support, and re-engaging patients lost to care. In Tanzania, the Community-Based HIV Services program is a nationwide cohort of CHWs supporting HIV care engagement. We enrolled a prospective cohort study of 80 people initiating HIV care at two Tanzanian clinics and conducted baseline and 3-month follow-up assessments to examine the potential influence of CHW support and other factors on patient early self-reported medication adherence, depression, anxiety, attitudes about medication, and HIV stigma. The vast majority of participants reported maintaining strong antiretroviral therapy (ART) adherence during the study and endorsed beliefs that ART is beneficial for them. However, there was high occurrence of likely depression and anxiety disorders in the study sample. Patient contact with CHWs at the clinic was unexpectedly low; fewer than two-thirds of participants were informed about the CHW program and fewer than one-third ever met with a CHW. Among participants who met with a CHW, there was mixed feedback about the helpfulness of the program, and contact with a CHW did not improve medication adherence at 3-month follow-up. Male participants, those with likely depression, and those who lived further from the clinic were significantly more likely to experience adherence challenges. The study findings indicate that CHWs are currently underutilized to provide patient support and may not be producing observable benefits to patients in this setting, representing a missed opportunity to address patient challenges, including depression and anxiety.

Systematic Review Estimating the Burden of Dementia in the Latin America and Caribbean Region: A Bayesian Approach

Background: The global burden of dementia has increasingly shifted to low- and middle-income regions that lack essential data for monitoring epidemiological progression, and policy and planning support. Drawing upon data that have emerged since the last known estimates published in 2015, this study aims to update dementia estimates in the Latin America and Caribbean (LAC) region for the years 2020, 2030, and 2050 through the application of a recently validated Bayesian approach for disease estimates useful when data sources are scarce.

Methods: A comprehensive parallel systematic review of PubMed, EMBASE, PsycINFO, Global Health, and LILACS was conducted to identify prospective population-based epidemiological studies on dementia published in English from 2013 to 2018 in LAC. English and non-English data cited by a recent review on dementia estimates in LAC were also examined for additional data. A Bayesian normal-normal hierarchical model (NNHM) was developed to estimate age-specific and age-adjusted dementia prevalence in people aged 60+. Using age-specific population projections from the UN, the total number of people affected by dementia for the years 2020, 2030, and 2050 were estimated.

Results: 1,414 studies were identified, of which only 7 met the inclusion criteria. The studies had 7,684 participants and 1,191 dementia cases. The age-standardized prevalence of all forms of dementia in LAC was 8% (95% CI: 5–11.5%) in people aged 60+. The estimated prevalence varied with age, increasing from 2.5% (95% CI: 0.08–4.0%) in the 60-69 age group, to 9.4% (95% CI: 5.4–13.2%) in the 70–79 age group and 28.9% (95% CI: 20.3–37.2%) in the ≥80 age group. The number of people age 60 and older living with dementia in LAC in 2020 was estimated at 6.86 (95% CI: 4.3–9.8) million, 9.94 (95% CI: 6.16–14.15) million in 2030, and 19.33 (95% CI: 12.3–13.6) million in 2050.

Conclusion: We project an upward disease trajectory for dementia in LAC countries. The projection is likely an underestimation of the true dementia burden given the underrepresentation of rural and socio-economically deprived populations. More research is urgently needed to improve the accuracy of disease estimates, guide clinicians to improve evaluations for earlier recognition of dementia, and support the development of effective policies for improving dementia prevention, diagnosis and clinical management in LAC's diverse and aging communities.

Barriers to and facilitators of employment of persons with disabilities in low- and middle-income countries: A scoping review

BACKGROUND

Unemployment rates for persons with disabilities in low- and middle-income countries (LMICs) are high. This is despite the call to action by the United Nations Convention on the Rights of Persons with Disabilities and Sustainable Development Goals aimed at improving the economic well-being of the marginalised. To improve the employment outcomes of persons with disabilities in these countries, factors that facilitate and hinder employment should be explored.

OBJECTIVES

This study explored barriers to and facilitators of employment for persons with disabilities in LMICs through a scoping review.

METHODS

A search strategy included a systematic search of nine databases using specific keywords. The International Classification of Functioning, Disability and Health (ICF) framework was used as a conceptual framework and barriers and facilitators were reported according to the domains of the ICF. Articles published between 2008 and 2020 were reviewed using a predefined criteria.

RESULTS

Thirty-two studies were identified in the review. Factors were identified in all domains of the ICF: (1) body function and body structure (12; 39%); (2) activities and participation (13; 42%); (3) personal factors (23; 74%); (4) environmental factors (27; 84%).

CONCLUSION

Factors that hinder and facilitate the participation of persons with disabilities in LMICs were mainly found in the environment, with personal factors also influencing participation. The presence of negative attitudes and lack of services mainly in health and transport were major factors within the environment whilst personals factors included the lack of educational qualifications and skills. These results indicate the importance of consideration of contextual factors when developing intervention strategies aimed at facilitating the employment of persons with disabilities in LMICs.

Breast cancer treatment: A phased approach to implementation

Optimal treatment outcomes for breast cancer are dependent on a timely diagnosis followed by an organized, multidisciplinary approach to care. However, in many low- and middle-income countries, effective care management pathways can be difficult to follow because of financial constraints, a lack of resources, an insufficiently trained workforce, and/or poor infrastructure. On the basis of prior work by the Breast Health Global Initiative, this article proposes a phased implementation strategy for developing sustainable approaches to enhancing patient care in limited-resource settings by creating roadmaps that are individualized and adapted to the baseline environment. This strategy proposes that, after a situational analysis, implementation phases begin with bolstering palliative care capacity, especially in settings where a late-stage diagnosis is common. This is followed by strengthening the patient pathway, with consideration given to a dynamic balance between centralization of services into centers of excellence to achieve better quality and decentralization of services to increase patient access. The use of resource checklists ensures that comprehensive therapy or palliative care can be delivered safely and effectively. Episodic or continuous monitoring with established process and quality metrics facilitates ongoing assessment, which should drive continual process improvements. A series of case studies provides a snapshot of country experiences with enhancing patient care, including the implementation of national cancer control plans in Kenya, palliative care in Romania, the introduction of a 1-stop clinic for diagnosis in Brazil, the surgical management of breast cancer in India, and the establishment of a women's cancer center in Ghana.

Evaluating chronic kidney disease in rural South Africa: comparing estimated glomerular filtration rate using point-of-care creatinine to iohexol measured GFR

OBJECTIVES

The prevalence of chronic kidney disease is rising rapidly in low- and middle-income countries. Serum creatinine and estimation of glomerular filtration rate (GFR) are critical diagnostic tools, yet access to centralised laboratory services remains limited in primary care resource-limited settings. The aim of this study was to evaluate point-of-care (POC) technologies for serum creatinine measurement and to compare their performance to a gold standard measurement using iohexol measured GFR (mGFR).

METHODS

POC creatinine was measured using iSTAT^® and StatSensor^® devices in capillary and venous whole blood, and laboratory creatinine was measured using the compensated kinetic Jaffe method in 670 participants from a rural area in South Africa. GFR estimating equations Chronic Kidney Disease Epidemiology Collaboration and Modification of Diet in Renal Disease (CKD-EPI and MDRD) for POC and laboratory creatinine were compared to iohexol mGFR.

RESULTS

Calculated GFR for laboratory and POC creatinine measurements overestimated GFR (positive bias of 1.9-34.1 mL/min/1.73 m²). However, all POC devices had less positive bias than the laboratory Jaffe method (1.9-14.7 vs. 34.1 for MDRD, and 8.4-19.9 vs. 28.6 for CKD-EPI). Accuracy within 30% of mGFR ranged from 0.56 to 0.72 for POC devices and from 0.36 to 0.43 for the laboratory Jaffe method. POC devices showed wider imprecision with coefficients of variation ranging from 4.6 to 10.2% compared to 3.5% for the laboratory Jaffe method.

CONCLUSIONS

POC estimated GFR (eGFR) showed improved performance over laboratory Jaffe eGFR, however POC devices suffered from imprecision and large bias. The laboratory Jaffe method performed poorly, highlighting the need for laboratories to move to enzymatic methods to measure creatinine.

Prevalence and factors associated with use of sleeping pills among older adults in Brazil

OBJECTIVES

Little is known about sleeping pills consumption among older adults in low- and middle-income countries. This study investigated the prevalence and factors associated with sleeping pills use among Brazilians aged 50 and over.

METHODS

A cross-sectional study was conducted using baseline data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil), a nationally representative study of persons aged 50 years and older (n = 9412). Univariate and bivariate analyses were used to describe the sample. Robust Poisson regression was employed to estimate prevalence ratios and predict probabilities.

KEY FINDINGS

Prevalence of sleeping pills use among older Brazilians was estimated at 16.8%, with considerable disparities related to gender (22.3% among women and 10.3% among men), race/skin colour (19.7% among whites and 11.9% among blacks) and geographic region (ranging from 5.9% in the North to 20.5% in the South). The multivariate analysis showed associations between sleeping pills consumption and sociodemographic factors (age, gender, race/skin colour, geographic region and income), health status/behaviour characteristics (poor self-rated health status, number of chronic conditions and alcohol consumption) and variables related to healthcare utilisation (number of visits, usual source of care, care coordination, doctor's awareness of all medication, difficulty in managing own medication and number of medicines).

CONCLUSIONS

Our work found that sleeping pills consumption is disproportionately prevalent among women, is associated with worse health status and increases with more medical office visits and use of additional medicines. Moreover, the large inexplicable variations in care deserve special attention from policy-makers and clinicians.

The development of hospital accreditation in low- and middle-income countries: a literature review

Hospital accreditation has been transferred from high-income countries (HICs) to many low- and middle-income countries (LMICs), supported by a variety of advocates and donor agencies. This review uses a policy transfer theoretical framework to present a structured analysis of the development of hospital accreditation in LMICs. The framework is used to identify how governments in LMICs adopted accreditation from other settings and what mechanisms facilitated and hindered the transfer of accreditation. The review examines the interaction between national and international actors, and how international organizations influenced accreditation policy transfer. Relevant literature was found by searching databases and selected websites; 78 articles were included in the analysis process. The review concludes that accreditation is increasingly used as a tool to improve the quality of healthcare in LMICs. Many countries have established national hospital accreditation programmes and adapted them to fit their national contexts. However, the implementation and sustainability of these programmes are major challenges if resources are scarce. International actors have a substantial influence on the development of accreditation in LMICs, as sources of expertise and pump-priming funding. There is a need to provide a roadmap for the successful development and implementation of accreditation programmes in low-resource settings. Analysing accreditation policy processes could provide contextually sensitive lessons for LMICs seeking to develop and sustain their national accreditation programmes and for international organizations to exploit their role in supporting the development of accreditation in LMICs.

Comparative Effectiveness of Reperfusion Strategies in Patients with ST-Segment Elevation Myocardial Infarction: A Secondary Analysis of the Acute Coronary Syndrome Quality Improvement in Kerala (ACS QUIK) Trial

Introduction:

Substantial heterogeneity exists in reperfusion strategies for patients with ST-segment myocardial infarction (STEMI) in low- and middle-income countries (LMICs). We sought to compare outcomes associated with primary percutaneous coronary intervention (PPCI) and non-primary percutaneous coronary intervention (nPPCI) reperfusion strategies in patients with STEMI in Kerala, India.

Methods:

We performed a retrospective analysis of patients with STEMI (n = 8665) from the Acute Coronary Syndrome Quality Improvement in Kerala (ACS QUIK) randomized trial receiving either PPCI (n = 6623) or nPPCI (n = 2042). nPPCI included all PCI strategies implemented when PPCI was not available including all post-fibrinolysis PCI strategies and PCI without fibrinolysis. Clinical outcomes among patients undergoing PPCI and nPPCI were compared after propensity-score matching. The main outcomes were the rates of in-hospital and 30-day major adverse cardiovascular events (MACE), defined as the composite of death, reinfarction, stroke, and major bleeding.

Results:

In the propensity-score matched cohort (n = 1266 in each group), nPPCI had longer symptom onset to hospital arrival time (347.5 vs. 195.0 minutes, p < 0.001), door to balloon time (108 minutes vs. 75 minutes, p < 0.001), and were less likely to receive a coronary stent (89.4% vs. 95%, p < 0.001), including drug-eluting stents (89.5% vs. 94.4%, p < 0.001). There were no clinically meaningful differences in discharge medical therapy. However, patients treated with nPPCI were less commonly referred for cardiac rehabilitation (20.2% vs. 24.2%; p = 0.019). In-hospital (3.6% vs. 3.3%, p = 0.74%) and 30-day (4.4% vs. 4.6%, p = 0.77) MACE did not differ between nPPCI and PPCI matched groups.

Conclusion:

In a large, contemporary population of STEMI patients from a LMIC, patients treated with a nPPCI reperfusion strategy had comparable short- and intermediate-term outcomes compared to PPCI despite differences in hospital presentation time and coronary stent use. These findings are reassuring but highlight the need for continued quality improvement in the delivery of STEMI care in resource-limited settings.

Cost-effectiveness analyses of breast cancer medications use in developing countries: a systematic review

BACKGROUND

Pharmacoeconomic evaluation is important for breast-cancer medications due to their high costs. To our knowledge, no systematic literature reviews of pharmacoeconomic studies for breast-cancer medication use are present in developing-countries.

OBJECTIVES

To systematically review the existing cost-effectiveness evaluations of breast-cancer medication in developing-countries.

METHODOLOGY

A systematic literature search was performed in PubMed, EMBASE, SCOPUS, and EconLit. Two researchers determined the final articles, extracted data, and evaluated their quality using the Quality of Health-Economic Studies (QHES) tool. The interclass-correlation-coefficient (ICC) was calculated to assess interrater-reliability. Data were summarized descriptively.

RESULTS

Fourteen pharmacoeconomic studies published from 2009 to 2019 were included. Thirteen used patient-life-years as their effectiveness unit, of which 10 used quality-adjusted life-years. Most of the evaluations focused on trastuzumab as a single agent or on regimens containing trastuzumab (n = 10). The conclusion of cost-effectiveness analysis varied among the studies. All the studies were of high quality (QHES score >75). Interrater reliability between the two reviewers was high (ICC = 0.76).

CONCLUSION

In many studies included in the review, the use of breast-cancer drugs in developing countries was not cost-effective. Yet, more pharmacoeconomic evaluations for the use of recently approved agents in different disease stages are needed in developing countries.

Multimorbidity patterns in low-middle and high income regions: a multiregion latent class analysis using ATHLOS harmonised cohorts

OBJECTIVES

Our aim was to determine clusters of non-communicable diseases (NCDs) in a very large, population-based sample of middle-aged and older adults from low- and middle-income (LMICs) and high-income (HICs) regions. Additionally, we explored the associations with several covariates.

DESIGN

The total sample was 72 140 people aged 50+ years from three population-based studies (English Longitudinal Study of Ageing, Survey of Health, Ageing and Retirement in Europe Study and Study on Global Ageing and Adult Health) included in the Ageing Trajectories of Health: Longitudinal Opportunities and Synergies (ATHLOS) project and representing eight regions with LMICs and HICs. Variables were previously harmonised using an ex-post strategy. Eight NCDs were used in latent class analysis. Multinomial models were made to calculate associations with covariates. All the analyses were stratified by age (50-64 and 65+ years old).

RESULTS

Three clusters were identified: 'cardio-metabolic' (8.93% in participants aged 50-64 years and 27.22% in those aged 65+ years), 'respiratory-mental-articular' (3.91% and 5.27%) and 'healthy' (87.16% and 67.51%). In the younger group, Russia presented the highest prevalence of the 'cardio-metabolic' group (18.8%) and England the 'respiratory-mental-articular' (5.1%). In the older group, Russia had the highest proportion of both classes (48.3% and 9%). Both the younger and older African participants presented the highest proportion of the 'healthy' class. Older age, being woman, widowed and with low levels of education and income were related to an increased risk of multimorbidity. Physical activity was a protective factor in both age groups and smoking a risk factor for the 'respiratory-mental-articular'.

CONCLUSION

Multimorbidity is common worldwide, especially in HICs and Russia. Health policies in each country addressing coordination and support are needed to face the complexity of a pattern of growing multimorbidity.

Availability, Price, and Affordability of Essential Medicines to Manage Noncommunicable Diseases: A National Survey From Nepal

The aim of this study was to evaluate the availability, price, and affordability of essential noncommunicable disease (NCD) medicines in Nepal. A cross-sectional survey was conducted in Nepal in 2015 using World Health Organization/Health Action International (WHO/HAI) methodology. We collected data on the availability and price of 60 essential NCD medicines from medicine distribution outlets in both the public and private health care sectors in 6 regions. Essential NCD medicines were more available in the private sector (78%) than the public sector (60%). Furosemide tablets were the cheapest (NPR 0.6/10 tablets) and streptokinase injections were the most expensive (NPR 2200/vial) drugs. There was no significant difference (P > .05) in availability and affordability of essential NCD medicines across the 6 survey areas. Treating selected NCD conditions with medicines was generally affordable, with 1 month of treatment costing no more than a day’s wage of the lowest paid unskilled government worker. The lower availability of NCD medicines in the public sector limits the effectiveness of the government’s policy of providing free health services at public facilities. Although NCD medicines were generally affordable, future health policy should aim to ensure improved equitable access to NCD medicines, particularly in public facilities.

Grief and Bereavement in Parents After the Death of a Child in Low- and Middle-Income Countries

While great strides have been made in improving childhood mortality, millions of children die each year with significant health-related suffering. More than 98% of these children live in low- and middle-income countries (LMICs). Efforts have been made to increase access to pediatric palliative care (PPC) services to address this suffering in LMICs through policy measures, educational initiatives, and access to essential medicines. However, a core component of high-quality PPC that has been relatively neglected in LMICs is grief and bereavement support for parents after the death of their child. This paper reviews the current literature on parental grief and bereavement in LMICs. This includes describing bereavement research in high-income countries (HICs), including its definition, adverse effect upon parents, and supportive interventions, followed by a review of the literature on health-related grief and bereavement in LMICs, specifically around: perinatal death, infant mortality, infectious disease, interventions used, and perceived need. More research is needed in grief and bereavement of parents in LMICs to provide them with the support they deserve within their specific cultural, social, and religious context. Additionally, these efforts in LMICs will help advance the field of parental grief and bereavement research as a whole.

A glimpse of hope: cardiac surgery in low- and middle-income countries (LMICs)

Currently, more than five times more people live in low- and middle-income countries (LMICs) than in high-income countries (HICs). As such, the downward trend in cardiac surgical needs in HICs reflects only the situation of one sixth of the world population while the vast majority living in LMICs has still no or limited access to life saving heart operations. In these countries, rheumatic heart disease (RHD) still accounts for a significant proportion of cardiac surgical needs. In low- and lower-middle income countries it remains the single most common cardiovascular disease in young adult and adolescent patients in need of heart surgery outweighing other indications such as congenital cardiac defects almost 4-fold. Compared to HICs with their predominance of calcific aortic stenosis in the elderly mitral valve surgery is required in >90% of the largely young patients with RHD in low-income countries (LICs) and still in 70% of the often middle aged patients in middle-income countries (MICs). Although recent government initiatives in LICs led to the establishment of local, independent cardiac surgical services gradually replacing fly-in missions, these centers still only cover less than 2% of the needs of their populations. In MICs, cardiac surgical needs continually grow with the emergence of degenerative diseases. As such, in spite of the concomitant growth of cardiac surgical capacity, significantly less than half the estimated patients in need have access. Capacities in LICs range from 0.5 to 7 cardiac operations/million population; 100-481/million in MICs and >1,200/million in HICs such as the USA and Germany. While a new level of awareness of the scope and magnitude of the problem has begun to emerge in LICs and the establishment of local cardiac surgical capacity has given rise to a glimpse of hope, the challenges of expanding these fledgling services to a significant proportion of the population still seem insurmountable. Challenges in MICs are on the other hand the widening gap between private cardiac medicine for the affluent few and overwhelmed public services for the many and the rural urban divide with the underappreciation of the ongoing dominance of RHD in the rural and indigent population on the other. Overshadowing all LMICs is the low level of valve-repair skills associated with insufficient cardiac surgical capacity and the unavailability of suitable replacement valves which address the young age of the patients and the difficulties of anticoagulation in a socioeconomic environment distinctly different from the elderly patients of HICs.

Pulmonary hypertension in low- and middle-income countries with focus on sub-Saharan Africa

Pulmonary hypertension (PH) is a devastating, progressive disease with increasingly debilitating symptoms and usually shortened overall life expectancy. This article reviews the global epidemiology of PH with focus on low- and middle-income countries (LMICs) and sub-Sahara African in particular. Although left ventricular heart disease is the most common cause globally, the main contributing risk factors in LMICs are chronic infectious diseases especially human immunodeficiency virus (HIV) and schistosomiasis. Other important risk factors of PH are rheumatic heart disease, untreated congenital heart disease (CHD), and sickle cell disease. Despite existing epidemiological data of PH risk factors suggesting a high prevalence in sub-Saharan Africa (SSA), the available literature is limited. International registries in LMICs like the pan African pulmonary hypertension cohort (PAPUCO) study are essential to provide information about the causes, treatment, outcome, and the natural course of PH in Africa and other parts of the world. In addition, there is a need to track diagnostic and management practices in order to develop suitable algorithms to diagnose PH in LMICs.

An overview of heart failure in low- and middle-income countries

Heart failure (HF) is a global public health concern with disproportionate socioeconomic, morbidity and mortality burden on low- and middle-income countries (LMICs). This review summarises contemporary data on the demographic and clinical characteristics, aetiologies, treatment, economic burden and outcomes of HF in LMICs. Patients with HF in LMICs are younger than those from high-income countries (HICs) and present at advanced stages of the disease. Hypertension, ischaemic heart disease (IHD), cardiomyopathy (CMO), and rheumatic heart disease (RHD) are the leading causes of HF in LMICs. The contribution of infectious diseases to HF remains prominent in many LMICs. Most health facilities in LMICs lack adequate diagnostic tools for HF, and the use of evidence-based medical and device therapies is suboptimal. Further, HF in LMICs is associated with prolonged hospital stay and high in-hospital and one-year mortality. Finally, HF has profound economic impact on individual patients who, mostly, have no health insurance, and on societies where patients are young, comprising those who have the greatest potential to contribute to economic productivity.

Cardiac arrhythmias in low- and middle-income countries

Many low- and middle-income countries (LMICs) are undergoing an epidemiological transition. With an improvement in socioeconomic conditions and an aging population, cardiovascular diseases (CVDs), like cardiac arrhythmias, are expected to increase in these countries. However, there are limited studies on the epidemiology and management of cardiac arrhythmias in LMICs. This review will highlight the unique challenges and opportunities that these countries face when managing cardiac arrhythmias.

Cervical spine pathology and treatment: a global overview

Cervical spine pathology is becoming increasingly prevalent with an aging world population and is associated with significant morbidity, affecting all areas of the world. This review was undertaken to provide a global perspective on cervical spine pathology, including epidemiology, burden of disease, access to care, and plan of care in both developed and developing low- and middle-income countries (LMICs). We found that epidemiology, access to care, plan of care, and health outcomes were relatively similar between nations with similar economies. However, these aspects change dramatically when comparing developing nations to LMICs, with LMICs displaying substantial barriers to care and subsequently higher rates of morbidity and mortality. There is currently a need for large-scale, global, prospective multicenter studies that analyze not only the epidemiology and treatment of cervical spine pathology, but also consider patient outcomes.

Intensive Care Unit Capacity Strain and Outcomes of Critical Illness in a Resource-Limited Setting: A 2-Hospital Study in South Africa

OBJECTIVE

To measure the association of intensive care unit (ICU) capacity strain with processes of care and outcomes of critical illness in a resource-limited setting.

METHODS

We performed a retrospective cohort study of 5332 patients referred to the ICUs at 2 public hospitals in South Africa using the country's first published multicenter electronic critical care database. We assessed the association between multiple ICU capacity strain metrics (ICU occupancy, turnover, census acuity, and referral burden) at different exposure time points (ICU referral, admission, and/or discharge) with clinical and process of care outcomes. The association of ICU capacity strain at the time of ICU admission with ICU length of stay (LOS), the primary outcome, was analyzed with a multivariable Cox proportional hazard model. Secondary outcomes of ICU triage decision (with strain at ICU referral), ICU mortality (with strain at ICU admission), and ICU LOS (with strain at ICU discharge), were analyzed with linear and logistic multivariable regression.

RESULTS

No measure of ICU capacity strain at the time of ICU admission was associated with ICU LOS, the primary outcome. The ICU occupancy at the time of ICU admission was associated with increased odds of ICU mortality (odds ratio = 1.07, 95% confidence interval: 1.02-1.11; P = .004), a secondary outcome, such that a 10% increase in ICU occupancy would be associated with a 7% increase in the odds of ICU mortality.

CONCLUSIONS

In a resource-limited setting in South Africa, ICU capacity strain at the time of ICU admission was not associated with ICU LOS. In secondary analyses, higher ICU occupancy at the time of ICU admission, but not other measures of capacity strain, was associated with increased odds of ICU mortality.

Intervention development for the indicated prevention of depression in later life: the "DIL" protocol in Goa, India

Because depression is a major source of the global burden of illness- related disability, developing effective strategies for reducing its incidence is an important public health priority, especially in low-income countries, where resources for treating depression are scarce. We describe in this report an intervention development project, funded by the US National Institute of Mental Health, to address "indicated" prevention of depression in older adults attending rural and urban primary care clinics in Goa, India. Specifically, participants in the "DIL" ("Depression in Later Life") trial were older adults living with mild, subsyndromal symptoms of depression and anxiety and thus at substantial risk for transitioning to fully syndromal major depression and anxiety disorders. Building upon the MANAS treatment trial ("Promoting Mental Health") led by Patel et al in the same locale, we present here lessons learned in the development and implementation of a protocol utilizing lay health counsellors (LHCs) who deliver a multi-component depression prevention intervention organized conceptually around Problem Solving Therapy for Primary Care (PST), with additional components addressing brief behavioural treatment of sleep disturbances such as insomnia, meeting basic social casework needs, and education in self- management of prevalent comorbid chronic diseases, such as diabetes mellitus. To our knowledge, DIL is the first randomized clinical trial addressing the prevention of depressive disorders ever conducted in a low- or middle-income country.

Community engagement in sexual health and uptake of HIV testing and syphilis testing among MSM in China: a cross-sectional online survey

INTRODUCTION

HIV and syphilis testing rates remain low among men who have sex with men (MSM) in low- and middle-income countries (LMICs). Community engagement has been increasingly used to promote HIV testing among key populations in high-income countries, often in settings with stronger civil society. This study aimed to assess socio-demographic, behavioural, and community engagement factors associated with HIV and syphilis testing among MSM in China.

METHODS

MSM ≥16 years old who had condomless sex in the past three months were recruited nationwide to complete a cross-sectional online survey in November 2015. Data were collected on socio-demographics, sexual behaviours, HIV testing, syphilis testing, and community engagement in sexual health. We defined community engagement in sexual health using six items assessing awareness and advocacy of sexual health programmes. The underlying factor structure of a 6-item community engagement scale was determined through exploratory factor analysis. Univariate and multivariable logistic regressions identified correlates of HIV and syphilis testing.

RESULTS

1189 MSM were recruited. 54% (647/1189) of men had ever tested for HIV and 30% (354/1189) had ever tested for syphilis. Factor analysis suggested three levels of community engagement (minimal, moderate, and substantial) and this model explained 79.5% of observed variance. A quarter (26%, 312/1189) reported none to minimal engagement, over one half (54%, 644/1189) reported moderate engagement, and a fifth (20%, 233/1189) reported substantial engagement. Multivariable logistic regression showed that MSM with greater community engagement in sexual health were more likely to have ever tested for HIV (substantial vs. no engagement: aOR 7.91, 95% CI 4.98-12.57) and for syphilis (substantial vs. no engagement: aOR 5.35, 95% CI 3.16-9.04).

CONCLUSION

HIV and syphilis testing are suboptimal among MSM in China. Community engagement may be useful for promoting testing in China and should be considered in intervention development and delivery. Further research is needed to better understand the role of LMIC community engagement in HIV interventions.

Power Difference and Risk Perception: Mapping Vulnerability within the Decision Process of Pregnant Women towards Clinical Trial Participation in an Urban Middle-Income Setting

To address the burden of maternal morbidity and mortality in low- and middle-income countries (LMICs), research with pregnant women in these settings is increasingly common. Pregnant women in LMIC-context may experience vulnerability related to giving consent to participate in a clinical trial. To recognize possible layers of vulnerability this study aims to identify factors that influence the decision process towards clinical trial participation of pregnant women in an urban middle-income setting. This qualitative research used participant observation, in-depth interviews, and focus group discussion with medical staff and pregnant women eligible for trial participation, at a regional hospital in Accra, Ghana. Besides lack of familiarity with modern scientific concepts, specific factors influencing the decision-making process were identified. These include a wide power difference between health provider and patient, and a different perception of risk through externalization of responsibility of risk management within a religious context as well as a context shaped by authority. Also, therapeutic misconception was observed. The combination of these factors ensued women to rely on the opinion of the medical professional, rather than being guided by their own motivation to participation. Although being a (pregnant) woman per se should not render the label of being vulnerable, this study shows there are factors that influence the decision process of pregnant woman towards trial participation in a LMIC context that can result in vulnerability. The identification of context-specific factors that can create vulnerability facilitates adaptation of the design and conduct of research in a culturally competent manner.

Continuous positive airway pressure (CPAP) to treat respiratory distress in newborns in low- and middle-income countries

Severe respiratory distress is a serious complication common to the three major causes of neonatal mortality and morbidity (prematurity, intra-partum-related hypoxia and infections). In low- and middle-income countries (LMICs), 20% of babies presenting with severe respiratory distress die.Continuous positive airway pressure (CPAP), is an effective intervention for respiratory distress in newborns and widely used in high-income countries. Following the development of simple, safe and relatively inexpensive CPAP devices, there is potential for large-scale implementation in the developing world.In this article, we describe existing CPAP systems and present a review of the current literature examining the effectiveness of CPAP compared to standard care (oxygen) in newborns with respiratory distress. We also discuss the evidence gap which needs to be addressed prior to its integration into health systems in LMICs.
