The role of 'hidden' community volunteers in community-based health service delivery platforms: examples from sub-Saharan Africa

Labour conditions in dual-cadre community health worker programmes: a systematic review

BACKGROUND

Health care delivered by community health workers reduces morbidity and mortality while providing a considerable return on investment. Despite growing consensus that community health workers, a predominantly female workforce, should receive a salary, many community health worker programmes take the form of dual-cadre systems, where a salaried cadre of community health workers works alongside a cadre of unsalaried community health workers. We aimed to determine the presence, prevalence, and magnitude of exploitation in national dual-cadre programmes.

METHODS

We did a systematic review of available evidence from peer-reviewed databases and grey literature from database inception to Aug 2, 2021, for studies on unsalaried community health worker cadres in dual-cadre systems. Editorials, protocols, guidelines, or conference reports were excluded in addition to studies about single-tier community health worker programmes and those reporting on only salaried cadres of community health workers in a dual-cadre system. We extracted data on remuneration, workload, task complexity, and self-reported experiences of community health workers. Three models were created: a minimum model with the shortest time and frequency per task documented in the literature, a maximum model with the longest time, and a median model. Labour exploitation was defined as being engaged in work below the country's minimum wage together with excessive work hours or complex tasks. The study was registered with PROSPERO, CRD42021271500.

FINDINGS

We included 117 reports from 112 studies describing community health workers in dual-cadre programmes across 19 countries. The majority of community health workers were female. 13 (59%) of 22 unsalaried community health worker cadres and one (10%) of ten salaried cadres experienced labour exploitation. Three (17%) of 18 unsalaried community health workers would need to work more than 40 h per week to fulfil their assigned responsibilities. Unsalaried community health worker cadres frequently reported non-payment, inadequate or inconsistent payment of incentives, and an overburdensome workload.

INTERPRETATION

Unsalaried community health workers in dual-cadre programmes often face labour exploitation, potentially leading to inadequate health-care provision. Labour laws must be upheld and the creation of professional community health worker cadres with fair contracts prioritised, international funding allocated to programmes that rely on unsalaried workers should be transparently reported, the workloads of community health workers should be modelled a priori and actual time use routinely assessed, community health workers should have input in policies that affect them, and volunteers should not be responsible for the delivery of essential health services.

FUNDING

None.

The experiences and challenges of community health volunteers as agents for behaviour change programming in Africa: a scoping review

Community health volunteers are considered a vital part of the community health structure in Africa. Despite this vital role in African health systems, very little is known about the community health volunteers’ day-to-day lived experiences providing services in communities and supporting other health workers. This scoping review aims to advance understanding of the day-to-day experiences of community health volunteers in Africa. In doing so, this review draws attention to these under-considered actors in African health systems and identifies critical factors and conditions that represent challenges to community health volunteers’ work in this context. Ultimately, our goal is to provide a synthesis of key challenges and considerations that can inform efforts to reduce attrition and improve the sustainability of community health volunteers in Africa. This scoping review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for scoping reviews checklist to achieve the objectives. A comprehensive search of six databases returned 2140 sources. After screening, 31 peer-reviewed studies were selected for final review. Analytical themes were generated based on the reviewers’ extraction of article data into descriptive themes using an inductive approach. In reviewing community health volunteers’ accounts of providing health services, five key challenges become apparent. These are: (1) challenges balancing work responsibilities with family obligations; (2) resource limitations; (3) exposure to stigma and harassment; (4) gendered benefits and risks; and (5) health-system level challenges. This scoping review highlights the extent of challenges community health volunteers must navigate to provide services in communities. Sustained commitment at the national and international level to understand the lived experiences of community health volunteers and mitigate common stressors these health actors face could improve their performance and inform future programs.

Community health workers at the dawn of a new era: 9. CHWs' relationships with the health system and communities

BACKGROUND

This is the ninth paper in our series, "Community Health Workers at the Dawn of a New Era". Community health workers (CHWs) are in an intermediary position between the health system and the community. While this position provides CHWs with a good platform to improve community health, a major challenge in large-scale CHW programmes is the need for CHWs to establish and maintain beneficial relationships with both sets of actors, who may have different expectations and needs. This paper focuses on the quality of CHW relationships with actors at the local level of the national health system and with communities.

METHODS

The authors conducted a selective review of journal articles and the grey literature, including case study findings in the 2020 book Health for the People: National CHW Programs from Afghanistan to Zimbabwe. They also drew upon their experience working with CHW programmes.

RESULTS

The space where CHWs form relationships with the health system and the community has various inherent strengths and tensions that can enable or constrain the quality of these relationships. Important elements are role clarity for all actors, working referral systems, and functioning supply chains. CHWs need good interpersonal communication skills, good community engagement skills, and the opportunity to participate in community-based organizations. Communities need to have a realistic understanding of the CHW programme, to be involved in a transparent process for selecting CHWs, and to have the opportunity to participate in the CHW programme. Support and interaction between CHWs and other health workers are essential, as is positive engagement with community members, groups, and leaders.

CONCLUSION

To be successful, large-scale CHW programmes need well-designed, effective support from the health system, productive interactions between CHWs and health system staff, and support and engagement of the community. This requires health sector leadership from national to local levels, support from local government, and partnerships with community organizations. Large-scale CHW programmes should be designed to enable local flexibility in adjusting to the local community context.

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: 5. Roles and tasks

BACKGROUND

This is the fifth of our 11-paper supplement on "Community Health Workers at the Dawn of a New Era." When planning new community health worker (CHW) roles or expanding existing roles, programme planners need to analyse global and local research evidence and evidence-based guidance on the effectiveness and safety of relevant tasks performed by CHWs.

METHODS

In this paper, we explore key areas of consideration when selecting roles and tasks; present current knowledge regarding these issues; and suggest how decision-makers could consider these issues when assigning tasks in their setting. This paper draws on the chapter "Community Health Worker Roles and Tasks" in Developing and Strengthening Community Health Worker Programs at Scale: A Reference Guide and Case Studies for Program Managers and Policymakers, as well as on a recently published compendium of 29 case studies of national CHW programmes and on recently published literature pertaining to roles and tasks of CHWs.

RESULTS

This paper provides a list of questions that aim to help programme planners think about important issues when determining CHW roles and tasks in their setting. Planners need to assess whether the recommended roles and tasks are considered acceptable and appropriate by their target population and by the CHWs themselves and those who support them. Planners also need to think about the practical and organizational implications of each task for their particular setting with regard to training requirements, health systems support, work location, workload, and programme costs.

CONCLUSION

When planning CHW roles and tasks, planners, programme implementers, and policy-makers should draw from global guidance and research evidence, but they also need to engage with the experiences, needs, and concerns of local communities and health workers. By drawing from both sources of information, they will stand a better chance of developing programmes that are effective in achieving their goals while remaining acceptable to those affected by them, feasible to implement, and sustainable over time.

Sources of nutrition information for Indonesian women during pregnancy: how is information sought and provided?

OBJECTIVE

Adequate and appropriate nutrition education is expected to contribute towards preventing risk of child stunting and maternal overweight/obesity. Understanding women's information-seeking behaviours is an important key step for health professionals and departments of health in order to improve the development of optimal and targeted nutrition education during pregnancy. This study investigated the experience of Indonesian women in seeking and receiving nutritional information during pregnancy and its relationship to women's socio-demographic and pregnancy characteristics.

DESIGN

An online cross-sectional study.

SETTING

Malang City, Indonesia.

PARTICIPANTS

Women who had given birth within the past 2 years (n 335).

RESULTS

All women in this study sought or received food and nutrition information from multiple sources, including social and health professional contacts and media sources. The women frequently discussed nutrition issues with their family, particularly their husband (98·2 %) and mother or mother-in-law (91·6 %). This study identified four groups of sources based on women's search habits. Women from high socio-economic strata were more likely to discuss food and nutrition issues or received nutrition information from obstetricians, their family or online sources (adjusted R2 = 26·3 %). Women from low socio-economic strata were more likely to receive nutrition information from midwives, health volunteers or Maternal and Child Health books (adjusted R2 = 14·5 %).

CONCLUSIONS

A variety of nutrition information sources needs to be provided for women from different socio-economic strata. Involvement of family members in antenatal nutrition education may improve the communication and effectiveness of young mothers' dietary and nutrition education.

An evaluation of self-management outcomes among chronic care patients in community home-based care programmes in rural Malawi: A 12-month follow-up study

This paper investigates the impact of community home-based care (CHBC) on self-management outcomes for chronically ill patients in rural Malawi. A pre- and post-evaluation survey was administered among 140 chronically ill patients with HIV and non-communicable diseases, newly enrolled in four CHBC programmes. We translated, adapted and administered scales from the Stanford Chronic Disease Self-Management Programme to evaluate patient's self-management outcomes (health status and self-efficacy), at four time points over a 12-month period, between April 2016 and May 2017. The patient's drop-out rate was approximately 8%. Data analysis included descriptive statistics, tests of associations, correlations and pairwise comparison of outcome variables between time points, and multivariate regression analysis to explore factors associated with changes in self-efficacy following CHBC interventions. The results indicate a reduction in patient-reported pain, fatigue and illness intrusiveness, while improvements in general health status and quality of life were not statistically significant. At baseline, the self-efficacy mean was 5.91, which dropped to 5.1 after 12 months. Factors associated with this change included marital status, education, employment and were condition-related; whereby self-efficacy for non-HIV and multimorbid patients was much lower. The odds for self-efficacy improvement were lower for patients with diagnosed conditions of longer duration. CHBC programme support, regularity of contact and proximal location to other services influenced self-efficacy. Programmes maintaining regular home visits had higher patient satisfaction levels. Our findings suggest that there were differential changes in self-management outcomes following CHBC interventions. While self-management support through CHBC programmes was evident, CHBC providers require continuous training, supervision and sustainable funding to strengthen their contribution. Furthermore, sociodemographic and condition-related factors should inform the design of future interventions to optimise outcomes. This study provides a systematic evaluation of self-management outcomes for a heterogeneous chronically ill patient population and highlights the potential and relevant contribution of CHBC programmes in improving chronic care within sub-Saharan Africa.

Indonesian antenatal nutrition education: A qualitative study of healthcare professional views

BACKGROUND

Early lifestyle intervention, including antenatal nutrition education, is required to reduce the triple burden of malnutrition. Understanding healthcare professionals' views and experiences is essential for improving future nutrition education programmes for Indonesian pregnant women. This study aimed to investigate the views of Indonesian antenatal healthcare professionals regarding nutrition education for pregnant women and the improvements required to provide more effective antenatal nutrition education.

METHODS

A descriptive qualitative study involved semi-structured interviews was conducted with 24 healthcare professionals, including nutritionists (n = 10), midwives (n = 9) and obstetricians (n = 5) in Malang, Indonesia, between December 2018 and January 2019. Data were analysed using thematic analysis.

RESULTS

The study identified four main themes. First, healthcare professionals were aware of the importance of providing antenatal nutrition education, which included supporting its targeted delivery. Second, there were differing views on who should provide nutrition education. Most midwives and obstetricians viewed nutritionists as the prime nutrition education provider. Nutritionists were confident in their capability to provide nutrition education. However, some nutritionists reported that only a few women visited primary health centres and received nutrition counselling via this pathway. Third, healthcare professionals revealed some barriers in providing education for women. These barriers included a limited number of nutritionists, lack of consistent guidelines, lack of healthcare professionals' nutrition knowledge and lack of time during antenatal care services. Fourth, participants expressed the need to strengthen some system elements, including reinforcing collaboration, developing guidelines, and enhancing capacity building to improve future antenatal nutrition education.

CONCLUSIONS

Healthcare professionals play a central role in the provision of antenatal nutrition education. This study highlighted the importance of educational models that incorporate various antenatal nutrition education delivery strategies. These methods include maximizing referral systems and optimizing education through multiple delivery methods, from digital modes to traditional face-to-face nutrition education in pregnancy classes and community-based health services.

Trends and Factors Associated with Healthcare Utilization for Childhood Diarrhea and Fever in Ethiopia: Further Analysis of the Demographic and Health Surveys from 2000 to 2016

Background

Healthcare use for childhood illness reduces the risk of under-five deaths from common preventable diseases. However, rates of healthcare seeking for childhood diarrhea and fever remain low in most low- and middle-income countries including Ethiopia. This study aimed to assess the trends and factors for healthcare diarrhea and fever in Ethiopia from 2000 to 2016.

Methods

Analysis of healthcare use for diarrhea and fever trends was done using data from four Ethiopian Demographic Health Surveys. Descriptive statistics were used to report sample characteristics and healthcare use for diarrhea and fever trends, and chi-square tests were used to assess associations between independent variables and healthcare utilization in each survey. Binary logistic regression analysis was fitted to find the factors related to healthcare utilization for diarrhea and fever. All variables with odds ratio p values <0.05 were considered as significant determinants of the outcome.

Results

Healthcare seeking for diarrheal illness significantly increased from 13% (95% CI: 12.5–13.5) in 2000 to 44% (95% CI: 43.2–44.78) in 2016, while healthcare uses for fever significantly increased from 22% (95% CI: 16.7–27.3) in 2000 to 35% (95% CI: 34.3–35.7) in 2016. Factors of healthcare seeking for diarrhea in 2000–2016 were as follows: maternal age <30 years, urban residence, being a male child, nonexposure to mass media and not hearing information about oral rehydration, no desire to have more children, poor wealth index, and region. Meanwhile, factors for healthcare seeking for fever in 2000–2016 were as follows: a long distance from the nearest health facilities, first birth order, nonexposure to mass media, no desire to have more children, maternal age <30 years, urban residence, region, absence of antenatal and postnatal care utilization, poor wealth index, and being born from uneducated mothers (p values <0.05 were considered as significant determinants of the outcome.

Conclusions

Factors associated with healthcare utilization for diarrhea and fever differed between 2000 and 2016. Though Ethiopia has achieved a significant reduction in under-five mortality, it needs to accelerate the reduction through strengthening healthcare utilization for common childhood illness to avoid deaths from preventable diseases.

Key challenges of health care workers in implementing the integrated management of childhood illnesses (IMCI) program: a scoping review

Background: Several evaluative studies demonstrate that a well-coordinated Integrated Management of Childhood Illnesses (IMCI) program can reduce child mortality. However, there is dearth of information on how frontline providers perceive IMCI and how, in their view, the program is implemented and how it could be refined and revitalized.Purpose: To determine the key challenges affecting IMCI implementation from the perspective of health care workers (HCWs) in primary health care facilities.Methods: A scoping review based on the five-step framework of Arskey and O'Malley was utilized to identify key challenges faced by HCWs implementing the IMCI program in primary health care facilities. A comprehensive search of peer-reviewed literature through PubMed, ScienceDirect, EBSCOhost and Google Scholar was conducted. A total of 1,475 publications were screened for eligibility and 41 publications identified for full-text evaluation. Twenty-four (24) published articles met our inclusion criteria, and were investigated to tease out common themes related to challenges of HCWs in terms of implementing the IMCI program.Results: Four key challenges emerged from our analysis: 1) Insufficient financial resources to fund program activities, 2) Lack of training, mentoring and supervision from the tertiary level, 3) Length of time required for effective and meaningful IMCI consultations conflicts with competing demands and 4) Lack of planning and coordination between policy makers and implementers resulting in ambiguity of roles and accountability. Although the IMCI program can provide substantial benefits, more information is still needed regarding implementation processes and acceptability in primary health care settings.Conclusion: Recognizing and understanding insights of those enacting health programs such as IMCI can spark meaningful strategic recommendations to improve IMCI program effectiveness. This review suggests four domains that merit consideration in the context of efforts to scale and expand IMCI programs.

Sub-national perspectives on the implementation of a national community health worker programme in Gauteng Province, South Africa

INTRODUCTION

In 2011, in line with principles for Universal Health Coverage, South Africa formalised community health workers (CHWs) into the national health system in order to strengthen primary healthcare. The national policy proposed that teams of CHWs, called Ward-based Primary Healthcare Outreach Teams (WBPHCOTs), supervised by a professional nurse were implemented. This paper explores WBPHCOTs' and managers' perspectives on the implementation of the CHW programme in one district in South Africa at the early stages of implementation guided by the Implementation Stages Framework.

METHODS

We conducted a qualitative study consisting of five focus group discussions and 14 in-depth interviews with CHWs, team leaders and managers. A content analysis of data was conducted.

RESULTS

There were significant weaknesses in early implementation resulting from a vague national policy and a rushed implementation plan. During the installation stage, adaptations were made to address gaps including the appointment of subdistrict managers and enrolled nurses as team leaders. Staff preparation of CHWs and team leaders to perform their roles was inadequate. To compensate, team members supported each another and assisted with technical skills where they could. Structural issues, such as CHWs receiving a stipend rather than being employed, were an ongoing implementation challenge. Another challenge was that facility managers were employed by the local government authority while the CHW programme was perceived to be a provincial programme.

CONCLUSION

The implementation of complex programmes requires a shared vision held by all stakeholders. Adaptations occur at different implementation stages, which require a feedback mechanism to inform the implementation in other settings. The CHW programme represented a policy advance but lacked detail with respect to human resources, budget, supervision, training and sustainability, which made it a difficult furrow to plough. This study points to how progressive reform remains fraught without due attention to the minutiae of practice.

The CORE Group Polio Project's Community Volunteers and Polio Eradication in Ethiopia: Self-Reports of Their Activities, Knowledge, and Contributions

In 2001, the CORE Group Polio Project (CGPP) began to support polio eradication initiatives in hard-to-reach pastoralist and semi-pastoralist high-risk border areas of Ethiopia by training and supporting community volunteers (CVs) for immunization promotion and community-based surveillance activities. This article describes the development and current status of the CGPP CV network in Ethiopia. It also reports the results of a 2016 survey of CVs. Community volunteers are selected jointly by the local community, local government officials, and local health facility staff. They work closely with the health extension worker in their area and are responsible for 50-100 households. More than 12,000 CVs have been trained and have reached six million people. They make routine home visits to 1) provide education on vaccine-preventable diseases, 2) promote healthy behaviors, 3) inform parents on how to access immunization services, and 4) report cases of acute flaccid paralysis, neonatal tetanus, and measles as well as births. The 2016 survey of 675 CVs demonstrated that 84.1% had conducted home visits in the previous month to 1) identify and register pregnant mothers and newborns, 2) provide health education, 3) conduct disease surveillance, and 4) search for and register immunization defaulters. Of the CVs, 98.2% reported that their work had led to improvements in the community. Knowledge of CVs about vaccine-preventable diseases was suboptimal. CVs expressed a desire for more training. Community volunteers have made notable contributions to polio eradication efforts in high-risk areas of Ethiopia as well as to immunization promotion and disease control more broadly.

Primary healthcare system performance in low-income and middle-income countries: a scoping review of the evidence from 2010 to 2017

INTRODUCTION

The 2018 Astana Declaration reaffirmed global commitment to primary healthcare (PHC) as a core strategy to achieve universal health coverage. To meet this potential, PHC in low-income and middle-income countries (LMIC) needs to be strengthened, but research is lacking and fragmented. We conducted a scoping review of the recent literature to assess the state of research on PHC in LMIC and understand where future research is most needed.

METHODS

Guided by the Primary Healthcare Performance Initiative (PHCPI) conceptual framework, we conducted searches of the peer-reviewed literature on PHC in LMIC published between 2010 (the publication year of the last major review of PHC in LMIC) and 2017. We also conducted country-specific searches to understand performance trajectories in 14 high-performing countries identified in the previous review. Evidence highlights and gaps for each topic area of the PHCPI framework were extracted and summarised.

RESULTS

We retrieved 5219 articles, 207 of which met final inclusion criteria. Many PHC system inputs such as payment and workforce are well-studied. A number of emerging service delivery innovations have early evidence of success but lack evidence for how to scale more broadly. Community-based PHC systems with supportive governmental policies and financing structures (public and private) consistently promote better outcomes and equity. Among the 14 highlighted countries, most maintained or improved progress in the scope of services, quality, access and financial coverage of PHC during the review time period.

CONCLUSION

Our findings revealed a heterogeneous focus of recent literature, with ample evidence for effective PHC policies, payment and other system inputs. More variability was seen in key areas of service delivery, underscoring a need for greater emphasis on implementation science and intervention testing. Future evaluations are needed on PHC system capacities and orientation toward social accountability, innovation, management and population health in order to achieve the promise of PHC.

Moving to a strong(er) community health system: analysing the role of community health volunteers in the new national community health strategy in Malawi

Since the Alma Ata Declaration in 1978, community health volunteers (CHVs) have been at the forefront, providing health services, especially to underserved communities, in low-income countries. However, consolidation of CHVs position within formal health systems has proved to be complex and continues to challenge countries, as they devise strategies to strengthen primary healthcare. Malawi's community health strategy, launched in 2017, is a novel attempt to harmonise the multiple health service structures at the community level and strengthen service delivery through a team-based approach. The core community health team (CHT) consists of health surveillance assistants (HSAs), clinicians, environmental health officers and CHVs. This paper reviews Malawi's strategy, with particular focus on the interface between HSAs, volunteers in community-based programmes and the community health team. Our analysis identified key challenges that may impede the strategy's implementation: (1) inadequate training, imbalance of skill sets within CHTs and unclear job descriptions for CHVs; (2) proposed community-level interventions require expansion of pre-existing roles for most CHT members; and (3) district authorities may face challenges meeting financial obligations and filling community-level positions. For effective implementation, attention and further deliberation is needed on the appropriate forms of CHV support, CHT composition with possibilities of co-opting trained CHVs from existing volunteer programmes into CHTs, review of CHT competencies and workload, strengthening coordination and communication across all community actors, and financing mechanisms. Policy support through the development of an addendum to the strategy, outlining opportunities for task-shifting between CHT members, CHVs' expected duties and interactions with paid CHT personnel is recommended.

Exploring the roles and factors influencing community health workers' performance in managing and referring severe acute malnutrition cases in two subdistricts in South Africa

As primary providers of preventive and curative community case management services in low- and middle-income countries (LMICs), community health workers (CHWs) have emerged as a formalised part of the health system (HS). However, discourses on their practices as formalised cadres of the HS are limited. Therefore, we examined their role in care, referral (to clinics) and rehabilitation of severe acute malnutrition (SAM) cases. Focusing on SAM was essential since it is a global public health problem associated with 30% of all South Africa's (SA's) child deaths in 2015. Guided by a policy analysis framework, a qualitative case study was conducted in two rural subdistricts of North West province. From April to August 2016, data collected from CHW's training manuals and guideline reviews, 20 patient record reviews and 15 in-depth interviews with four CHW leaders and 11 CHWs. Using thematic content analysis which was guided by the Walt and Gilson policy triangle, data was manually analysed to derive emerging themes on case management and administrative structures. The study found that although CHWs were responsible for identifying, referring, and rehabilitating SAM cases, they neglected curative roles of stabilisation before referral and treatment of uncomplicated cases. Such limitations resulted from restrictive CHW policies, inadequate training, lack of supportive supervision and essential resources. Concurrently, the CHW program was based on weak operational and administrative structures which challenged CHWs practices. Poor curative components and weak operational structures in this context compromised the use of CHWs in LMICs to strengthen primary healthcare. If CHWs are to contribute to Sustainable Development Goal (SDG) 3 by reducing SAM mortality, strategies on community management of acute malnutrition coupled with thorough training, supportive supervision, firm operational structures, adequate resources and providers' motivation should be adopted by governments.

Community-Based Interventions for Newborns in Ethiopia (COMBINE): Cost-effectiveness analysis

About 87 000 neonates die annually in Ethiopia, with slower progress than for child deaths and 85% of births are at home. As part of a multi-country, standardized economic evaluation, we examine the incremental benefit and costs of providing management of possible serious bacterial infection (PSBI) for newborns at health posts in Ethiopia by Health Extension Workers (HEWs), linked to improved implementation of existing policy for community-based newborn care (Health Extension Programme). The government, with Save the Children/Saving Newborn Lives and John Snow, Inc., undertook a cluster randomized trial. Both trial arms involved improved implementation of the Health Extension Programme. The intervention arm received additional equipment, support and supervision for HEWs to identify and treat PSBI. In 2012, ∼95% of mothers in the study area received at least one pregnancy or postnatal visit in each arm, an average of 5.2 contacts per mother in the intervention arm (4.9 in control). Of all visits, 79% were conducted by volunteer community health workers. HEWs spent around 9% of their time on the programme. The financial cost per mother and newborn was $34 (in 2015 USD) in the intervention arm ($27 in control), economic costs of $37 and $30, respectively. Adding PSBI management at community level was estimated to reduce neonatal mortality after day 1 by 17%, translating to a cost per DALY averted of $223 or 47% of the GDP per capita, a highly cost-effective intervention by WHO thresholds. In a routine situation, the intervention programme cost would represent 0.3% of public health expenditure per capita and 0.5% with additional monthly supervision meetings. A platform wide approach to improved supervision including a dedicated transport budget may be more sustainable than a programme-specific approach. In this context, strengthening the existing HEW package is cost-effective and also avoids costly transfers to health centres/hospitals.

Community-Based Management of Acute Malnutrition to Reduce Wasting in Urban Informal Settlements of Mumbai, India: A Mixed-Methods Evaluation

Under the NGO–government partnership, wasting among children under age 3 decreased by 28% in intervention areas and by only 5% in comparison areas. Success factors included persuading and engaging with communities including delivery of tailored information, close presence and supervision of field staff, and holistic management of other issues beyond acute malnutrition. This intensive approach may be challenging for the government to adapt effectively at large scale.

Background:

We evaluated an adaptation of a large-scale community-based management of acute malnutrition program run by an NGO with government partnerships, in informal settlements of Mumbai, India. The program aimed to reduce the prevalence of wasting among children under age 3 and covered a population of approximately 300,000.

Methods:

This study used a mixed-methods approach including a quasi-experimental design to compare prevalence estimates of wasting in intervention areas with neighboring informal settlements. Cross-sectional data were collected from March through November 2014 for the baseline and October through December 2015 for the endline. Endline data were analyzed using mixed-effects logistic regression models, adjusting for child, maternal, and household characteristics. In addition, we conducted in-depth interviews with 37 stakeholders (13 staff and 24 mothers) who reported on salient features that contributed to successful implementation of the program.

Results:

We interviewed 2,578 caregivers at baseline and 3,455 at endline in intervention areas. In comparison areas, we interviewed 2,082 caregivers at baseline and 2,122 at endline. At endline, the prevalence of wasting decreased by 28% (18% to 13%) in intervention areas and by 5% (16.9% to 16%) in comparison areas. Analysis of the endline data indicated that children in intervention areas were significantly less likely to be malnourished (adjusted odds ratio, 0.81; confidence interval, 0.67 to 0.99). Stakeholders identified 4 main features as contributing to the success of the program: (1) tailoring and reinforcement of information provided to caregivers in informal settings, (2) constant field presence of staff, (3) holistic case management of issues beyond immediate malnourishment, and (4) persistence of field staff in persuading reluctant families. Staff capabilities were enhanced through training, stringent monitoring mechanisms, and support from senior staff in tackling difficult cases.

Conclusion:

NGO–government partnerships can revitalize existing community-based programs in urban India. Critical to success are processes that include reinforced knowledge-building of caregivers, a high level of field support and encouragement to the community, and constant monitoring and follow-up of cases by all staff levels.

Approaches and strategies used in the training and supervision of Health Extension Workers (HEWs) delivering integrated community case management (iCCM) of childhood illness in Ethiopia: a qualitative rapid appraisal

Background

Globally, preventable and treatable childhood conditions such as pneumonia, diarrhoea, malaria, malnutrition and newborn conditions still account for 75% of under-five mortality. To reduce the mortality rate from these conditions, Ethiopia launched an ambitious Health Extension Programme (HEP) in 2003. Trained Community Health Workers (CHWs), named Health Extension Workers (HEWs) were deployed to deliver a package of care which includes integrated Community Case-Management (iCCM) of common childhood diseases.

Objectives

This qualitative study aimed to explore approaches and strategies used in the HEW training and supervision as part of an evaluation of the Catalytic Initiative to Save a Million Lives.

Method

A qualitative rapid appraisal study using focus group discussions and in-depth interviews was conducted.

Results

Training of HEWs followed a cascaded training of trainer approach supported by implementing partners under guidance of the Ministry of Health. A comprehensive planning phase enabled good coverage of districts and consistency in training approaches. Training was complemented by on-going supportive supervision. HEW motivation was enhanced through regular review meetings and opportunities for career progression.

Conclusion

These findings describe a thorough approach to training and supervision of HEWs delivering iCCM in rural Ethiopia. Ongoing investments by partners will be critical for long-term sustainability.

Reduction in child mortality in Ethiopia: analysis of data from demographic and health surveys

Background

To examine changes in under–5 mortality, coverage of child survival interventions and nutritional status of children in Ethiopia between 2000 and 2011. Using the Lives Saved Tool, the impact of changes in coverage of child survival interventions on under–5 lives saved was estimated.

Methods

Estimates of child mortality were generated using three Ethiopia Demographic and Health Surveys undertaken between 2000 and 2011. Coverage indicators for high impact child health interventions were calculated and the Lives Saved Tool (LiST) was used to estimate child lives saved in 2011.

Results

The mortality rate in children younger than 5 years decreased rapidly from 218 child deaths per 1000 live births (95% confidence interval 183 to 252) in the period 1987–1991 to 88 child deaths per 1000 live births in the period 2007–2011 (78 to 98). The prevalence of moderate or severe stunting in children aged 6–35 months also declined significantly. Improvements in the coverage of interventions relevant to child survival in rural areas of Ethiopia between 2000 and 2011 were found for tetanus toxoid, DPT3 and measles vaccination, oral rehydration solution (ORS) and care–seeking for suspected pneumonia. The LiST analysis estimates that there were 60 700 child deaths averted in 2011, primarily attributable to decreases in wasting rates (18%), stunting rates (13%) and water, sanitation and hygiene (WASH) interventions (13%).

Conclusions

Improvements in the nutritional status of children and increases in coverage of high impact interventions most notably WASH and ORS have contributed to the decline in under–5 mortality in Ethiopia. These proximal determinants however do not fully explain the mortality reduction which is plausibly also due to the synergistic effect of major child health and nutrition policies and delivery strategies.

"Helping my neighbour is like giving a loan…" -the role of social relations in chronic illness in rural Uganda

BACKGROUND

Understanding individuals' experience of accessing care and tending to various other needs during chronic illness in a rural context is important for health systems aiming to increase access to healthcare and protect poor populations from unreasonable financial hardship. This study explored the impact on households of access to free healthcare and how they managed to meet needs during chronic illness.

METHODS

Rich data from the life stories of individuals from 22 households in rural south-western Uganda collected in 2009 were analysed.

RESULTS

The data revealed that individuals and households depend heavily on their social relations in order to meet their needs during illness, including accessing the free healthcare and maintaining vital livelihood activities. The life stories illustrated ways in which households draw upon social relations to achieve the broader social protection necessary to prevent expenses becoming catastrophic, but also demonstrated the uncertainty in relying solely on informal relations.

CONCLUSION

Improving access to healthcare in a rural context greatly depends on broader social protection. Thus, the informal social protection that already exists in the form of strong reciprocal social relations must be acknowledged, supported and included in health policy planning.

Effectiveness of interventions to reduce household air pollution and/or improve health in homes using solid fuel in low-and-middle income countries: A systematic review and meta-analysis

BACKGROUND

Cookstove intervention programs have been increasing over the past two (2) decades in Low and Middle Income Countries (LMICs) across the globe. However, there remains uncertainty regarding the effects of these interventions on household air pollution concentrations, personal exposure concentrations and health outcomes.

OBJECTIVES

The primary objective was to determine if household air pollution (HAP) interventions were associated with improved indoor air quality (IAQ) in households in LMICs. Given the potential impact of HAP interventions on health, a secondary objective was to evaluate the effectiveness of HAP interventions to improve health in populations receiving these interventions.

DATA SOURCES

OVID Medline, Ovid Embase, SCOPUS and PubMED were searched from their inception until December 2015 with no restrictions on study design. The WHO Global database of household air pollution measurements and Members' archives were also reviewed together with the reference lists of identified reviews and relevant articles.

STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTION

We considered randomized controlled trials, or non-randomized control trials, or before-and-after studies; original studies; studies conducted in a LMIC (based on the United Nations Human Development Report released in March 2013 (World Bank, 2013); interventions that were explicitly aimed at improving IAQ and/or health from solid fuel use; studies published in a peer-reviewed journal or student theses or reports; studies that reported on outcomes which was indicative of IAQ or/and health. There was no restriction on the type of comparator (e.g. household receiving plancha vs. household using traditional cookstove) used in the intervention study.

STUDY APPRAISAL AND SYNTHESIS METHODS

Five review authors independently used pre-designed data collection forms to extract information from the original studies and assessed risk of bias using the Effective Public Health Practice Project (EPHPP). We computed standardized weighted mean difference (SMD) using random-effects models. Heterogeneity was computed using the Q and I2-statistics. We examined the influence of various characteristics on the study-specific effect estimates by stratifying the analysis by population type, study design, intervention type, and duration of exposure monitoring. The trim and fill method was used to assess the potential impact of missing studies.

RESULTS

Fifty-five studies met our a priori inclusion criteria and were included in the systematic review. Fifteen studies provided 43 effect estimates for our meta-analysis. The largest improvement in HAP was observed for average particulate matter (PM) (SMD=1.57) concentrations in household kitchens (1.03), followed by daily personal average concentrations of PM (1.18), and carbon monoxide (CO) concentrations in kitchens. With respect to personal PM, significant improvement was observed in studies of children (1.26) and studies monitoring PM for ≥24h (1.32). This observation was also noted in terms of studies of kitchen concentrations of CO. A significant improvement was also observed for kitchen levels of PM in both adult populations (1.56) and in RCT/cohort designs (1.59) involving replacing cookstoves without chimneys. Our findings on health outcomes were inconclusive.

LIMITATIONS, CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

We observed high statistical between study variability in the study-specific estimate. Thus, care should be taken in concluding that HAP interventions - as currently designed and implemented - support reductions in the average kitchen and personal levels of PM and CO. Further, there is limited evidence that current stand-alone HAP interventions yield any health benefits. Post-intervention levels of pollutants were generally still greatly in excess of the relevant WHO guideline and thus a need to promote cleaner fuels in LMICs to reduce HAP levels below the WHO guidelines.

Geographic information system for improving maternal and newborn health: recommendations for policy and programs

This correspondence argues and offers recommendations for how Geographic Information System (GIS) applied to maternal and newborn health data could potentially be used as part of the broader efforts for ending preventable maternal and newborn mortality. These recommendations were generated from a technical consultation on reporting and mapping maternal deaths that was held in Washington, DC from January 12 to 13, 2015 and hosted by the United States Agency for International Development's (USAID) global Maternal and Child Survival Program (MCSP). Approximately 72 participants from over 25 global health organizations, government agencies, donors, universities, and other groups participated in the meeting.The meeting placed emphases on how improved use of mapping could contribute to the post-2015 United Nation's Sustainable Development Goals (SDGs), agenda in general and to contribute to better maternal and neonatal health outcomes in particular. Researchers and policy makers have been calling for more equitable improvement in Maternal and Newborn Health (MNH), specifically addressing hard-to-reach populations at sub-national levels. Data visualization using mapping and geospatial analyses play a significant role in addressing the emerging need for improved spatial investigation at subnational scale. This correspondence identifies key challenges and recommendations so GIS may be better applied to maternal health programs in resource poor settings. The challenges and recommendations are broadly grouped into three categories: ancillary geospatial and MNH data sources, technical and human resources needs and community participation.

Household air pollution and the sustainable development goals

Globally, 41% of households, over 2.8 billion people, rely on solid fuels (coal and biomass) for cooking and heating. In developing countries in Asia and sub-Saharan Africa where these fuels are predominantly used, women who are customarily responsible for cooking, and their young children, are most exposed to the resulting air pollution. Solid fuels are still in widespread use and it appears that intervention efforts are not keeping pace with population growth in developing countries. Here we pinpoint the challenges and identify opportunities for addressing household air pollution while mitigating global climate change and promoting the sustainable development goals.

We recommend the following actions: implementation of the WHO indoor air quality guidelineson household fuel combustion; effective promotion and dissemination of improved cookstoves through formation of country alliances for clean cookstoves; expansion of liquefied petroleum gas production facilities and distribution networks; harnessing renewable energy potential; promotion of biogas production at both household and community level; ensuring improved ventilation of homes through education and enforcement of building standards; and exploiting opportunities in the health and other sectors for changing health-damaging cooking behaviour.

Niger's Child Survival Success, Contributing Factors and Challenges to Sustainability: A Retrospective Analysis

BACKGROUND

Household surveys undertaken in Niger since 1998 have revealed steady declines in under-5 mortality which have placed the country 'on track' to reach the fourth Millennium Development goal (MDG). This paper explores Niger's mortality and health coverage data for children under-5 years of age up to 2012 to describe trends in high impact interventions and the resulting impact on childhood deaths averted. The sustainability of these trends are also considered.

METHODS AND FINDINGS

Estimates of child mortality using the 2012 Demographic and Health Survey were developed and maternal and child health coverage indicators were calculated over four time periods. Child survival policies and programmes were documented through a review of documents and key informant interviews. The Lives Saved Tool (LiST) was used to estimate the number of child lives saved and identify which interventions had the largest impact on deaths averted. The national mortality rate in children under-5 decreased from 286 child deaths per 1000 live births (95% confidence interval 177 to 394) in the period 1989-1990 to 128 child deaths per 1000 live births in the period 2011-2012 (101 to 155), corresponding to an annual rate of decline of 3.6%, with significant declines taking place after 1998. Improvements in the coverage of maternal and child health interventions between 2006 and 2012 include one and four or more antenatal visits, maternal Fansidar and tetanus toxoid vaccination, measles and DPT3 vaccinations, early and exclusive breastfeeding, oral rehydration salts (ORS) and proportion of children sleeping under an insecticide-treated bed net (ITN). Approximately 26,000 deaths of children under-5 were averted in 2012 due to decreases in stunting rates (27%), increases in ORS (14%), the Hib vaccine (14%), and breastfeeding (11%). Increases in wasting and decreases in vitamin A supplementation negated some of those gains. Care seeking at the community level was responsible for an estimated 7,800 additional deaths averted in 2012. A major policy change occurred in 2006 enabling free health care provision for women and children, and in 2008 the establishment of a community health worker programme.

CONCLUSION

Increases in access and coverage of care for mothers and children have averted a considerable number of childhood deaths. The 2006 free health care policy and health post expansion were paramount in reducing barriers to care. However the sustainability of this policy and health service provision is precarious in light of persistently high fertility rates, unpredictable GDP growth, a high dependence on donor support and increasing pressures on government funding.
