Development assistance for community health workers in 114 low- and middle-income countries, 2007-2017

Equity effect of a community-based primary healthcare program on the incidence of childhood morbidity in rural Northern Ghana

BACKGROUND

Childhood morbidity is a precursor and contributor to under-five child mortality. Community-based primary healthcare programs are culturally responsive and low-cost strategies for delivering maternal and child health services in rural communities.

AIM

To evaluate the equity effect of the Ghana Essential Health Intervention Program (GEHIP) - a five-year community-based primary healthcare program - on childhood morbidity.

METHODS

GEHIP was implemented in the Upper East region of Northern Ghana. Household baseline and end line surveys conducted in 2010/2011 and 2014/2015, respectively, from both intervention and comparison districts were used to assess three childhood morbidity conditions: maternal recall of neonatal illness, the incidence of diarrhoea, and fever. Difference-in-differences analysis, mean comparison test, and multivariate logistic regressions are used to assess the effect of GEHIP exposure on these three childhood morbidity conditions.

RESULTS

Baseline sample data of 2,911 women and end line sample of 2,829 women were included in this analysis. There was generally more reduction in all three childhood morbidity conditions in intervention communities relative to comparison communities. Diarrhoea and fever had a statistically significant treatment effect (AOR = 0.95, p-value<0.01 and AOR = 0.94, p-value<0.001). Results of equity analysis indicate significant mean reductions for both the poor and non-poor for neonatal illness and diarrhea, while only the intervention group had a significant reduction for both poor and non-poor for fever. Regression analysis shows no significant equity/inequity effects of GEHIP on the incidence of diarrhoea and fever. Neonatal illness, however, shows significant effects of wealth within the intervention group.

CONCLUSION

This study shows that GEHIP contributed significantly to childhood morbidity reduction. This implies that community-based strategies have the potential to improve child health and contribute to the attainment of the United Nations sustainable development goal related to child health. Specific targeted measures are recommended to ensure both the poor and relatively better-off benefit from interventions.

Evolution and effectiveness of bilateral and multilateral development assistance for health: a mixed-methods review of trends and strategic shifts (1990-2022)

BACKGROUND

Development assistance for health (DAH) plays a vital role in supporting health programmes in low- and middle-income countries. While DAH has historically focused on infectious diseases and maternal and child health, there is a lack of comprehensive analysis of DAH trends, strategic shifts and their impact on health systems and outcomes. This study aims to provide a comprehensive review of DAH from 1990 to 2022, examining its evolution and funding allocation shifts.

METHODS

We conducted a mixed-methods review, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A systematic literature search was performed across PubMed, Embase, Web of Science and the Cochrane databases, yielding 102 eligible studies. Quantitative data were obtained from the Institute for Health Metrics and Evaluation database, covering DAH data from 1990 to 2022. Qualitative data were analysed through thematic synthesis based on the WHO's six health system building blocks.

RESULTS

The DAH has predominantly focused on HIV/AIDS and maternal and child health. Despite the increasing global burden of non-communicable diseases (NCDs), the proportion of DAH allocated to NCDs remained low, increasing only from 1% in 1990 to 2% in 2022. Similarly, the overall funding for health system strengthening decreased from 19% in 1990 to 7% in 2022. Major contributors to DAH included the USA, the UK and the Bill & Melinda Gates Foundation. While associations between DAH and improvements in certain health outcomes were observed, establishing causality is challenging due to multiple influencing factors. The COVID-19 pandemic underscored the importance of robust health systems. However, DAH allocation did not show any substantial shift towards health system strengthening during this period. Economic evaluations calculated the median incremental cost-effectiveness ratio of DAH interventions, CONCLUSIONS: This study reviews DAH trends from 1990 to 2022, showing a predominant focus on HIV/AIDS and maternal and child health, with insufficient attention to NCDs and health system strengthening. Despite the increasing burden of NCDs and the impact of COVID-19, DAH priorities have not significantly shifted, highlighting the need for ongoing evaluation and strategic adjustments. To enhance DAH effectiveness, it is crucial to adopt a more balanced approach and also align interventions with needs from recipient countries and implement evidence-based strategies with continuous monitoring and evaluation.

Global development assistance for early childhood care and education in 134 low- and middle-income countries, 2007-2021

INTRODUCTION

Low- and middle-income countries (LMICs) often dedicate limited domestic funds to expand quality early childhood care and education (ECCE), making complementary international donor support potentially important. However, research on the allocation of international development assistance for ECCE has been limited.

METHODS

We analysed data from the Creditor Reporting System on aid projects to assess global development assistance for ECCE in 134 LMICs from 2007 to 2021. By employing keyword-searching and funding-allocation methods, we derived two estimates of ECCE aid: a lower-bound estimate comprising projects primarily focusing on ECCE and an upper-bound estimate comprising projects with both primary and partial ECCE focus, as well as those that could benefit ECCE but did not include ECCE keywords. We also assessed aid directed to conflict-affected countries and to ECCE projects integrating COVID-19-related activities.

RESULTS

Between 2007 and 2021, the lower-bound ECCE aid totaled US$3646 million, comprising 1.7% of the total US$213 279 million allocated to education. The World Bank led in ECCE aid, contributing US$1944 million (53.3% out of total ECCE aid). Low-income countries received less ECCE aid per child before 2016, then started to catch up but experienced a decrease from US$0.8 (2020) per child to US$0.6 (2021) per child. Funding for ECCE projects with COVID-19 activities decreased from a total of US$50 million in 2020 to US$37 million in 2021, representing 11.4% and 6.6% of annual total ECCE aid, respectively. Over 15 years, conflict-affected countries received an average of US$0.3 per child, a quarter of the aid received by non-conflict-affected countries (US$1.2 per child).

CONCLUSION

Although ECCE aid increased significantly between 2007 and 2021, its proportion of total educational aid fell short of UNICEF's suggested 10% minimum. Recommendations include increasing the share of ECCE aid in total educational aid, increasing aid to low-income and conflict-affected countries, and investing more in preparing ECCE programmes for future global crises.

Transition and change: opportunities and challenges of CHW programme reform for community health systems and vertical disease programmes in Liberia

BACKGROUND

Globally, community health worker (CHW) programmes are critical to addressing health worker shortages and have been recognised as critical pillars within the drive towards universal health coverage (UHC). In 2016, the Liberian Ministry of Health launched the National Community Health Services Policy 2016-2021, which included significant CHW programme reform to address ongoing health workforce capacity gaps in the country. However, little consideration was given to the impact of such reforms on ongoing health interventions that rely heavily on the use of CHW cadres. Our study explores how CHW programme reform in Liberia influenced performance of CHWs involved in the delivery of Neglected Tropical Disease (NTD) programmes to elucidate how health systems reform can impact the delivery of routine health interventions and vice versa.

METHODS

We used a qualitative case study approach conducted between March 2017 and August 2018. Our instrumental case study approach uses qualitative methods, including document review of five CHW and NTD program-related policy documents; 25 key informant interviews with facility, county, and national level decision-makers; and 42 life and job histories with CHWs in Liberia. Data were analysed using a thematic framework approach, guided by Kok et al. framework of CHW performance. Data were coded in QRS NVIVO 11 Pro.

RESULTS

Our findings show that CHW programme reform provides opportunities and challenges for supporting enhanced CHW performance. In relation to health system hardware, we found that CHW programme reform provides better opportunities for: formal recognition of CHWs; strengthening capacity for effective healthcare delivery at the community level through improved and formalised training; a more formal supervision structure; and provision of monthly incentives of 70 US dollars. Efficiency gaps in routine intervention delivery can be mitigated through the strengthening of these hardware components. Conversely, supervision deficits in routine CHW functioning can be supported through health interventions. In relation to systems software, we emphasise the ongoing importance of community engagement in CHW selection that is responsive to gendered power hierarchies and accompanied by gendered transformative approaches to improving literacy.

CONCLUSIONS

This study shows how CHW programme reform provides opportunities and challenges for health system strengthening that can both positively and negatively impact the functioning of routine health interventions. By working together, CHW programmes and routine health interventions have the opportunity to leverage mutually beneficial support for CHWs, which can enhance overall systems functioning by enhancing CHW performance.

The Journey of Zanzibar's Digitally Enabled Community Health Program to National Scale: Implementation Report

BACKGROUND

While high-quality primary health care services can meet 80%-90% of health needs over a person's lifetime, this potential is severely hindered in many low-resource countries by a constrained health care system. There is a growing consensus that effectively designed, resourced, and managed community health worker programs are a critical component of a well-functioning primary health system, and digital technology is recognized as an important enabler of health systems transformation.

OBJECTIVE

In this implementation report, we describe the design and rollout of Zanzibar's national, digitally enabled community health program-Jamii ni Afya.

METHODS

Since 2010, D-tree International has partnered with the Ministry of Health Zanzibar to pilot and generate evidence for a digitally enabled community health program, which was formally adopted and scaled nationally by the government in 2018. Community health workers use a mobile app that guides service delivery and data collection for home-based health services, resulting in comprehensive service delivery, access to real-time data, efficient management of resources, and continuous quality improvement.

RESULTS

The Zanzibar government has documented increases in the delivery of health facilities among pregnant women and reductions in stunting among children younger than 5 years since the community health program has scaled. Key success factors included starting with the health challenge and local context rather than the technology, usage of data for decision-making, and extensive collaboration with local and global partners and funders. Lessons learned include the significant time it takes to scale and institutionalize a digital health systems innovation due to the time to generate evidence, change opinions, and build capacity.

CONCLUSIONS

Jamii ni Afya represents one of the world's first examples of a nationally scaled digitally enabled community health program. This implementation report outlines key successes and lessons learned, which may have applicability to other governments and partners working to sustainably strengthen primary health systems.

Adoption of mHealth Technologies by Community Health Workers to Improve the Use of Maternal Health Services in Sub-Saharan Africa: Protocol for a Mixed Method Systematic Review

BACKGROUND

Studies have shown that mobile health technologies (mHealth) enhance the use of maternal health services. However, there is limited evidence of the impact of mHealth use by community health workers (CHWs) on the use of maternal health services in sub-Saharan Africa.

OBJECTIVE

This mixed method systematic review will explore the impact of mHealth use by CHWs on the use of the maternal health continuum of care (antenatal care, intrapartum care, and postnatal care [PNC]), as well as barriers and facilitators of mHealth use by CHWs when supporting maternal health services.

METHODS

We will include studies that report the impact of mHealth by CHWs on the use of antenatal care, facility-based births, and PNC visits in sub-Saharan Africa. We will search 6 databases (MEDLINE, CINAHL, Web of Science, Embase, Scopus, and Africa Index Medicus), with additional articles identified from Google Scholar and manual screening of references of the included studies. The included studies will not be limited by language or year of publication. After study selection, 2 independent reviewers will perform title and abstract screening, followed by full-text screening to identify the final papers to be included. Data extraction and risk-of-bias assessment will be performed using Covidence software by 2 independent reviewers. We will use a Mixed Methods Appraisal Tool to perform risk-of-bias assessments on all included studies. Finally, we will perform a narrative synthesis of the outcomes, integrating information about the effect of mHealth on maternal health use and barriers and facilitators of mHealth use. This protocol follows the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols) guidelines.

RESULTS

In September 2022, we conducted an initial search in the eligible databases. After removing duplicates, we identified 1111 studies that were eligible for the title and abstract screening. We will finalize the full-text assessment for eligibility, data extraction, assessment of methodological quality, and narrative synthesis by June 2023.

CONCLUSIONS

This systematic review will present new and up-to-date evidence on the use of mHealth by CHWs along the pregnancy, childbirth, and PNC continuum of care. We anticipate the results will inform program implementation and policy by highlighting the potential impacts of mHealth and presenting contextual factors that should be addressed to ensure the success of the programs.

The use of medicinal plants in the prevention of COVID-19 using the Health Belief Model: A survey based on the Iranian population

BACKGROUND

Because of the spread of coronavirus disease 2019 (COVID-19), the preventive measures have increased, such as focusing on the use of medicinal plants in most communities, including Iran. The purpose of this study was to identify the knowledge, attitude, and performance of individuals toward the use of medicinal plants and to identify the predictors of the use of medicinal plants in the prevention of COVID-19.

MATERIALS AND METHODS

This descriptive-analytical study (February-April 2021) was performed on 3840 Iranian men and women aged 20-70 years selected as a multi-stage cluster study. At the first stage, all provinces were divided into five regions: North, South, East, West, and Center. In the second stage, a provincial center and a city were randomly selected from each region (North: Sari, Babol; South: Bushehr, Bandar Genaveh; East: Mashhad, Sabzevar; West: Hamedan, Toisarkan; Center: Yazd, Ardakan). Data were collected by a researcher-made scale based on the Health Belief Model (HBM). Data analysis was performed applying Pearson correlation coefficient, logistic regression, and linear regression.

RESULTS

The results showed that people have relatively high knowledge and positive attitude toward the use of medicinal plants in prevention of COVID-19. The most important reason for positive attitude was the perceived benefits with the mean of 75.06%. Also, half of the people had poor performance. Correlation coefficient showed that the use of medicinal plants with perceived sensitivity (p = 0.000, r = 0.3), perceived benefits (p = 0.012, r = 0.126), perceived barriers (p = 0.000, r = 0.179), and perceived self-efficacy (p = 0.000, r = 0.305) had a significant correlation. The strongest correlation between perceived self-efficacy was observed with the use of herbs in prevention of COVID-19. The HBM constructs can predict 26% of the variance for the use of medicinal plants in the prevention of COVID-19, among which perceived self-efficacy (β = 0.230) was the most powerful predictor.

CONCLUSION

Based on the results, the predictive role of self-efficacy constructs for the use of medicinal plants in prevention of COVID-19 has been confirmed according to the HBM. Therefore, methods of increasing self-efficacy such as training programs and providing appropriate intervention models can be used not only as promoters of using medicinal plants in prevention of COVID-19 but also for improving people's performance in the proper use of medicinal plants.

Agentes Comunitárias de Saúde na pandemia de Covid-19: scoping review

RESUMO Este artigo teve por objetivo sistematizar e analisar a literatura que aborda o trabalho das Agentes Comunitárias de Saúde (ACS) no enfrentamento da pandemia de Covid-19. Trata-se de uma revisão de escopo, realizada na Embase, Lilacs, SciELO, Medline e Cochrane Library. Envolve publicações no período de janeiro a dezembro de 2020, tendo os estudos selecionados sido submetidos à análise, considerando as seguintes categorias: práticas, formação, condições de trabalho e legitimidade. Foram incluídos 29 estudos na revisão cujo cenário de atuação das ACS foram países da África, América do Sul, América do Norte, Ásia e Europa. Os resultados revelaram enfoques diversificados de práticas nos países estudados que envolvem ações de cuidado, vigilância, comunicação e educação em saúde, práticas administrativas, articulação intersetorial e mobilização social. A formação recebida parece não corresponder ao rol de práticas e impacto esperado do trabalho das ACS. As condições de trabalho continuam precarizadas com alguns incentivos extras sendo ofertados em diferentes cenários. O reconhecimento e a legitimidade perante as autoridades sanitárias revelam a disputa em torno do próprio rumo dos modelos de atenção à saúde e abrangência dos sistemas de proteção social nos diversos países.

Community Health Workers in the Covid-19 pandemic: scoping review

ABSTRACT This paper aimed to systematize and analyze the literature that addresses the role of Community Health Workers (CHWs) in addressing the Covid-19 pandemic. This scoping review was conducted in the Embase, Lilacs, SciELO, Medline, and Cochrane Virtual Libraries databases. It includes publications from January to December 2020, and the selected studies were submitted to analysis, considering the following categories: practices, training, working conditions, and legitimacy. Twenty-nine studies were included in the review whose CHW performance backdrops were African, South American, North American, Asian, and European countries. The results revealed diversified approaches to practice in the countries studied that involve care, surveillance, health communication, education, administrative, intersectoral articula- tion, and social mobilization actions. The training received does not seem to correspond to the list of practices and expected impact of the CHWs. Working conditions remain substandard, with some extra incentives offered in different backdrops. The recognition and legitimacy before the health authorities reveal the dispute over the direction of health care models and the scope of social protection systems in different countries.

Community health workers at the dawn of a new era: 11. CHWs leading the way to "Health for All"

BACKGROUND

This is the concluding paper of our 11-paper supplement, "Community health workers at the dawn of a new era".

METHODS

We relied on our collective experience, an extensive body of literature about community health workers (CHWs), and the other papers in this supplement to identify the most pressing challenges facing CHW programmes and approaches for strengthening CHW programmes.

RESULTS

CHWs are increasingly being recognized as a critical resource for achieving national and global health goals. These goals include achieving the health-related Sustainable Development Goals of Universal Health Coverage, ending preventable child and maternal deaths, and making a major contribution to the control of HIV, tuberculosis, malaria, and noncommunicable diseases. CHWs can also play a critical role in responding to current and future pandemics. For these reasons, we argue that CHWs are now at the dawn of a new era. While CHW programmes have long been an underfunded afterthought, they are now front and centre as the emerging foundation of health systems. Despite this increased attention, CHW programmes continue to face the same pressing challenges: inadequate financing, lack of supplies and commodities, low compensation of CHWs, and inadequate supervision. We outline approaches for strengthening CHW programmes, arguing that their enormous potential will only be realized when investment and health system support matches rhetoric. Rigorous monitoring, evaluation, and implementation research are also needed to enable CHW programmes to continuously improve their quality and effectiveness.

CONCLUSION

A marked increase in sustainable funding for CHW programmes is needed, and this will require increased domestic political support for prioritizing CHW programmes as economies grow and additional health-related funding becomes available. The paradigm shift called for here will be an important step in accelerating progress in achieving current global health goals and in reaching the goal of Health for All.

Community health workers at the dawn of a new era: 1. Introduction: tensions confronting large-scale CHW programmes

BACKGROUND

Community health worker (CHW) programmes are again receiving more attention in global health, as reflected in important recent WHO guidance. However, there is a risk that current CHW programme efforts may result in disappointing performance if those promoting and delivering them fail to learn from past efforts. This is the first of a series of 11 articles for a supplement entitled "Community Health Workers at the Dawn of a New Era".

METHODS

Drawing on lessons from case studies of large well-established CHW programmes, published literature, and the authors' experience, the paper highlights major issues that need to be acknowledged to design and deliver effective CHW programmes at large scale. The paper also serves as an introduction to a set of articles addressing these issues in detail.

RESULTS

The article highlights the diversity and complexity of CHW programmes, and offers insights to programme planners, policymakers, donors, and others to inform development of more effective programmes. The article proposes that be understood as actors within community health system(s) and examines five tensions confronting large-scale CHW programmes; the first two tensions concern the role of the CHW, and the remaining three, broader strategic issues: 1) What kind of an actor is the CHW? A lackey or a liberator? Provider of clinical services or health promoter? 2) Lay versus professional? 3) Government programme at scale or nongovernmental organization-led demonstration project? 4) Standardized versus tailored to context? 5) Vertical versus horizontal?

CONCLUSION

CHWs can play a vital role in primary healthcare, but multiple conditions need to be met for them to reach their full potential.

Community health workers at the dawn of a new era: 4. Programme financing

BACKGROUND

This is the fourth of our 11-paper supplement on "Community Health Workers at the Dawn of New Era". Here, we first make the case for investing in health programmes, second for investing in human resources for health, third for investing in primary healthcare (PHC) workers, and finally for investing in community health workers (CHWs).

METHODS

Searches of peer-reviewed journals and the grey literature were conducted with a focus on community health programme financing. The literature search was supplemented with a search of the grey literature for information about national health sector plans, community health strategies/policies, and costing information from databases of various countries' ministries of health, and finally a request for information from in-country partners.

RESULTS

The global shortage of human resources for health is projected to rise to 18 million health workers by 2030, with more acute shortages in Africa and South Asia. CHWs have an important role to play in mitigating this shortage because of their effectiveness (when properly trained and supported) and the feasibility of their deployment. Data are limited on the costs of current CHW programmes and how they compare to government and donor expenditures for PHC and for health services more broadly. However, available data from 10 countries in Africa indicate that the median per capita cost of CHW programmes is US$ 4.77 per year and US$ 2574 per CHW, and the median monthly salary of CHWs in these same countries is US$ 35 per month. For a subset of these countries for which spending for PHC is available, governments and donors spend 7.7 times more on PHC than on CHW programming, and 15.4 times more on all health expenditures. Even though donor funding for CHW programmes is a tiny portion of health-related donor support, most countries rely on donor support for financing their CHW programmes.

CONCLUSION

The financing of national CHW programmes has been a critical element that has not received sufficient emphasis in the academic literature on CHW programmes. Increasing domestic government funding for CHW programmes is a priority. In order to ensure growth in funding for CHW programmes, it will be important to measure CHW programme expenditures and their relationship to expenditures for PHC and for all health-related expenditures.

Pragmatic economic evaluation of community-led delivery of HIV self-testing in Malawi

INTRODUCTION

Community-based strategies can extend coverage of HIV testing and diagnose HIV at earlier stages of infection but can be costly to implement. We evaluated the costs and effects of community-led delivery of HIV self-testing (HIVST) in Mangochi District, Malawi.

METHODS

This economic evaluation was based within a pragmatic cluster-randomised trial of 30 group village heads and their catchment areas comparing the community-led HIVST intervention in addition to the standard of care (SOC) versus the SOC alone. The intervention involved mobilising community health groups to lead 7-day HIVST campaigns including distribution of HIVST kits. The SOC included facility-based HIV testing services. Primary costings estimated economic costs of the intervention and SOC from the provider perspective, with costs annualised and measured in 2018 US$. A postintervention survey captured individual-level data on HIV testing events, which were combined with unit costs from primary costings, and outcomes. The incremental cost per person tested HIV-positive and associated uncertainty were estimated.

RESULTS

Overall, the community-led HIVST intervention costed $138 624 or $5.70 per HIVST kit distributed, with test kits and personnel the main contributing costs. The SOC costed $263 400 or $4.57 per person tested. Individual-level provider costs were higher in the community-led HIVST arm than the SOC arm (adjusted mean difference $3.77, 95% CI $2.44 to $5.10; p<0.001), while the intervention effect on HIV positivity varied based on adjustment for previous diagnosis. The incremental cost per person tested HIV positive was $324 but increased to $1312 and $985 when adjusting for previously diagnosed self-testers or self-testers on treatment, respectively. Community-led HIVST demonstrated low probability of being cost-effective against plausible willingness-to-pay values, with HIV positivity a key determinant.

CONCLUSION

Community-led HIVST can provide HIV testing at a low additional unit cost. However, adding community-led HIVST to the SOC was not likely to be cost-effective, especially in contexts with low prevalence of undiagnosed HIV.

Effect of community-led delivery of HIV self-testing on HIV testing and antiretroviral therapy initiation in Malawi: A cluster-randomised trial

BACKGROUND

Undiagnosed HIV infection remains substantial in key population subgroups including adolescents, older adults, and men, driving ongoing transmission in sub-Saharan Africa. We evaluated the impact, safety, and costs of community-led delivery of HIV self-testing (HIVST), aiming to increase HIV testing in underserved subgroups and stimulate demand for antiretroviral therapy (ART).

METHODS AND FINDINGS

This cluster-randomised trial, conducted between October 2018 and July 2019, used restricted randomisation (1:1) to allocate 30 group village head clusters in Mangochi district, Malawi to the community-led HIVST intervention in addition to the standard of care (SOC) or the SOC alone. The intervention involved mobilising community health groups to lead the design and implementation of 7-day HIVST campaigns, with cluster residents (≥15 years) eligible for HIVST. The primary outcome compared lifetime HIV testing among adolescents (15 to 19 years) between arms. Secondary outcomes compared: recent HIV testing (in the last 3 months) among older adults (≥40 years) and men; cumulative 6-month incidence of ART initiation per 100,000 population; knowledge of the preventive benefits of HIV treatment; and HIV testing stigma. Outcomes were measured through a post-intervention survey and at neighboring health facilities. Analysis used intention-to-treat for cluster-level outcomes. Community health groups delivered 24,316 oral fluid-based HIVST kits. The survey included 90.2% (3,960/4,388) of listed participants in the 15 community-led HIVST clusters and 89.2% (3,920/4,394) of listed participants in the 15 SOC clusters. Overall, the proportion of men was 39.0% (3,072/7,880). Most participants obtained primary-level education or below, were married, and reported a sexual partner. Lifetime HIV testing among adolescents was higher in the community-led HIVST arm (84.6%, 770/910) than the SOC arm (67.1%, 582/867; adjusted risk difference [RD] 15.2%, 95% CI 7.5% to 22.9%; p < 0.001), especially among 15 to 17 year olds and boys. Recent testing among older adults was also higher in the community-led HIVST arm (74.5%, 869/1,166) than the SOC arm (31.5%, 350/1,111; adjusted RD 42.1%, 95% CI 34.9% to 49.4%; p < 0.001). Similarly, the proportions of recently tested men were 74.6% (1,177/1,577) and 33.9% (507/1,495) in the community-led HIVST and SOC arms, respectively (adjusted RD 40.2%, 95% CI 32.9% to 47.4%; p < 0.001). Knowledge of HIV treatment benefits and HIV testing stigma showed no differences between arms. Cumulative incidence of ART initiation was respectively 305.3 and 226.1 per 100,000 population in the community-led HIVST and SOC arms (RD 72.3, 95% CI -36.2 to 180.8; p = 0.18). In post hoc analysis, ART initiations in the 3-month post-intervention period were higher in the community-led HIVST arm than the SOC arm (RD 97.7, 95% CI 33.4 to 162.1; p = 0.004). HIVST uptake was 74.7% (2,956/3,960), with few adverse events (0.6%, 18/2,955) and at US$5.70 per HIVST kit distributed. The main limitations include the use of self-reported HIV testing outcomes and lack of baseline measurement for the primary outcome.

CONCLUSIONS

In this study, we found that community-led HIVST was effective, safe, and affordable, with population impact and coverage rapidly realised at low cost. This approach could enable community HIV testing in high HIV prevalence settings and demonstrates potential for economies of scale and scope.

Health for the People: Past, Current, and Future Contributions of National Community Health Worker Programs to Achieving Global Health Goals

National community health worker programs are at the dawn of a new era, given the growing recognition of their importance for achieving global health goals and for controlling the COVID-19 pandemic. Now is the time to provide them with the respect and funding that they need and deserve.

Community Health Worker Program Sustainability in Africa: Evidence From Costing, Financing, and Geospatial Analyses in Mali

Understanding specific program costs through efficiency analyses and geospatial targeting allows national stakeholders to make strategic, targeted investments, making the first steps toward sustainability. Costs required for community health worker programs can be reduced without sacrificing quality, and spending can be geographically targeted to optimize service use by rural populations. Results from Mali provide an example for other sub-Saharan African countries.

Background:

In Mali, community health workers (CHWs) deliver essential community care (ECC) to rural populations. The dominance of external funding for the program threatens the sustainability of this critical workforce as donor financing decreases. This article summarizes results of analyses aimed at assisting Mali's decision makers and leaders in initiating a transition to a sustainable CHW program supported by domestic funding through strategic and rational investment.

Methods:

Data on ECC implementation norms, workforce, coverage, utilization, cost, and geospatial features were collected between 2016 and 2019. The data informed interlinked CHW financing analyses—situational, services costing, efficiency, and geospatial mapping. Analysis showed distribution of reported expenditures, estimates of required CHW funding, cost-saving options, and spatially visualized discrepancies between spending estimates and normative costs.

Results:

Thirteen financing sources contributed to CHW program expenditures, 88% of which were from international donors, for a package of 23 curative, preventive, and promotive interventions. In 2015, the CHW program spent US$13.01 million; an estimated US$8.36 million would have been needed to achieve the same service volume under standard care protocols. Medicines and start-up training had US$6.88 million more than needed; supervision, program management, and recurrent training components were underfunded by US$2.2 million. Cost-saving opportunities of US$6.16 million were identified in 41 of 44 districts. Funding reallocation opportunities (after meeting technical efficiency requirements) were identified in 20 of 44 districts (US$2.56 million). Use of geospatial targeting and mapping suggests district- and village-level reallocation options for theoretical funding surpluses.

Conclusion:

CHW costs can be significantly reduced without sacrificing service technical quality. Spending can be geographically targeted to optimize service use by rural populations. Efficiency analyses provide evidence to build stronger engagement, support improved decision making, efficiently prioritize resources, and target investments for sustainable financing of CHW programs.

Mind the Global Community Health Funding Gap

Community health workers play a critical role in providing both essential health services and pandemic response. Community health demonstrates a strong return on investment, but funding for this sector is limited and fragmented. Understanding the underlying costs of a community health system is crucial for both planning and policy; the data demonstrate a strong investment case.

Applying the Community Health Worker Coverage and Capacity Tool for Time-Use Modeling for Program Planning in Rwanda and Zanzibar

Community health worker (CHW) programs are a critical component of health systems, notably in lower- and middle-income countries. However, when policy recommendations exceed what is feasible to implement, CHWs are overstretched by the volume of activities, implementation strength is diluted, and programs fail to produce promised outcomes. To counteract this, we developed a time-use modeling tool-the CHW Coverage and Capacity (C3) Tool-and used it with government partners in Rwanda and Zanzibar to address common policy questions related to CHW needs, coverage, and time optimization.In Rwanda, the C3 Tool was used to analyze 2 well-established cadres of CHWs and 1 new one. The well-established CHW cadres were within a "manageable" workload range whereas the new cadre was projected to achieve less than half of assigned activities. This is informing ongoing changes to the CHWs' scopes of work. In Zanzibar, the C3 Tool was used to update the national community health strategy to include community health volunteers (CHVs) for the first time and determine how many CHVs were needed. The tool projected that 2,200 CHVs could achieve approximately 90% coverage of all defined services. Based on these figures, Zanzibar updated its national community health strategy, which officially launched in February 2020.We discuss lessons from these 2 experiences. Translating analysis into decision making depends not only on the programmatic will and motivation of governments but also on finding opportune timing for when policy and program processes allow for optimization of CHW investments. Further research is needed but our experience supports the value of a modeling tool to ground program plans within estimated constraints on CHW time.

Is patient navigation a solution to the problem of "leaving no one behind"? A scoping review of evidence from low-income countries

Patient navigation interventions, which are designed to enable patients excluded from health systems to overcome the barriers they face in accessing care, have multiplied in high-income countries since the 1990s. However, in low-income countries (LICs), indigents are generally excluded from health policies despite the international paradigm of universal health coverage (UHC). Fee exemption interventions have demonstrated their limits and it is now necessary to act on other dimensions of access to healthcare. However, there is a lack of knowledge about the interventions implemented in LICs to support the indigents throughout their care pathway. The aim of this paper is to synthesize what is known about patient navigation interventions to facilitate access to modern health systems for vulnerable populations in LICs. We therefore conducted a scoping review to identify all patient navigation interventions in LICs. We found 60 articles employing a total of 48 interventions. Most of these interventions targeted traditional beneficiaries such as people living with HIV, pregnant women and children. We utilized the framework developed by Levesque et al. (Patient-centred access to health care: conceptualising access at the interface of health systems and populations. Int J Equity Health 2013;12:18) to analyse the interventions. All acted on the ability to perceive, 34 interventions on the ability to reach, 30 on the ability to engage, 8 on the ability to pay and 6 on the ability to seek. Evaluations of these interventions were encouraging, as they often appeared to lead to improved health indicators and service utilization rates and reduced attrition in care. However, no intervention specifically targeted indigents and very few evaluations differentiated the impact of the intervention on the poorest populations. It is therefore necessary to test navigation interventions to enable those who are worst off to overcome the barriers they face. It is a major ethical issue that health policies leave no one behind and that UHC does not benefit everyone except the poorest.

Cost-effectiveness of community health systems strengthening: quality improvement interventions at community level to realise maternal and child health gains in Kenya

INTRODUCTION

Improvements in maternal and infant health outcomes are policy priorities in Kenya. Achieving these outcomes depends on early identification of pregnancy and quality of primary healthcare. Quality improvement interventions have been shown to contribute to increases in identification, referral and follow-up of pregnant women by community health workers. In this study, we evaluate the cost-effectiveness of using quality improvement at community level to reduce maternal and infant mortality in Kenya.

METHODS

We estimated the cost-effectiveness of quality improvement compared with standard of care treatment for antenatal and delivering mothers using a decision tree model and taking a health system perspective. We used both process (antenatal initiation in first trimester and skilled delivery) and health outcomes (maternal and infant deaths averted, as well as disability-adjusted life years (DALYs)) as our effectiveness measures and actual implementation costs, discounting costs only. We conducted deterministic and probabilistic sensitivity analyses.

RESULTS

We found that the community quality improvement intervention was more cost-effective compared with standard community healthcare, with incremental cost per DALY averted of $249 under the deterministic analysis and 76% likelihood of cost-effectiveness under the probabilistic sensitivity analysis using a standard threshold. The deterministic estimate of incremental cost per additional skilled delivery was US$10, per additional early antenatal care presentation US$155, per maternal death averted US$5654 and per infant death averted US$37 536 (2017 dollars).

CONCLUSIONS

This analysis shows that the community quality improvement intervention was cost-effective compared with the standard community healthcare in Kenya due to improvements in antenatal care uptake and skilled delivery. It is likely that quality improvement interventions are a good investment and may also yield benefits in other health areas.

Compensation models for community health workers: Comparison of legal frameworks across five countries

Background

Despite the life-saving work they perform, community health workers (CHWs) have long been subject to global debate about their remuneration. There is now, however, an emerging consensus that CHWs should be paid. As the discussion evolves from whether to financially remunerate CHWs to how to do so, there is an urgent need to better understand the types of CHW payment models and their implications.

Methods

This study examines the legal framework on CHW compensation in five countries: Brazil, Ghana, Nigeria, Rwanda, and South Africa. In order to map the characteristics of each approach, a review of the regulatory framework governing CHW compensation in each country was undertaken. Law firms in each of the five countries were engaged to support the identification and interpretation of relevant legal documents. To guide the search and aid in the creation of uniform country profiles, a standardized set of questions was developed, covering: (i) legal requirements for CHW compensation, (ii) CHW compensation mechanisms, and (iii) CHW legal protections and benefits.

Results

The five countries profiled represent possible archetypes for CHW compensation: Brazil (public), Ghana (volunteer-based), Nigeria (private), Rwanda (cooperatives with performance based incentives) and South Africa (hybrid public/private). Advantages and disadvantages of each model with respect to (i) CHWs, in terms of financial protection, and (ii) the health system, in terms of ease of implementation, are outlined.

Conclusions

While a strong legal framework does not necessarily translate into high-quality implementation of compensation practices, it is the first necessary step. Certain approaches to CHW compensation – particularly public-sector or models with public sector wage floors – best institutionalize recommended CHW protections. Political will and long-term financing often remain challenges; removing ecosystem barriers – such as multilateral and bilateral restrictions on the payment of salaries – can help governments institutionalize CHW payment.
