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: 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: 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.

The Critical Role and Evaluation of Community Mobilizers in Polio Eradication in Remote Settings in Africa and Asia.

This article assesses the CORE Group Polio Project (CGPP) experience over a 20-year period in 5 countries. It examines how a program designed to provide social mobilization to eradicate one disease, and which did so effectively, functioned within the general framework of community health workers (CHWs). Vertical health programs often have limited impact on broader community health. CGPP has a 20-year history of social mobilization and effective program interventions. This history provided an opportunity to assess how CGPP community mobilizers (CMs) functioned in polio and maternal and child health. The Updated Program Functionality Matrix for Optimizing Community Health Programs tool of the CHW Assessment and Improvement Matrix (AIM) was used to examine CGPP CM roles across different contexts. The analysis determined that CGPP CMs met the basic level of functioning (level 3) for 6 of the 10 components of the AIM tool. This cross-country descriptive analysis of the CGPP demonstrates the importance of embracing the full range of CHW AIM components, even in a vertical program. Use of data, community involvement, local adaptation, and linkage with the health system are especially critical for success. This general lesson could be applied to other community mobilization and disease/epidemic control initiatives, especially as we face the issues of the COVID-19 pandemic.

The CORE Group Polio Project: An Overview of Its History and Its Contributions to the Global Polio Eradication Initiative.

The CORE Group Polio Project (CGPP) has contributed to polio eradication by successfully engaging civil society, particularly the non-governmental organization (NGO) community. This engagement, which began with a grant from the U.S. Agency for International Development in 1999, has contributed to improvements in routine immunization programs, polio campaign quality, and surveillance for acute flaccid paralysis in many challenging geographic areas. The CGPP has worked closely with polio eradication partners in a collaborative and supportive role. The CGPP has focused largely on high-risk areas with marginalized or hard-to-reach populations where health systems and immunization programs have also been weak and where transmission of poliovirus had not been stopped. The CGPP has engaged local civic leaders and communities in ways to complement top-down vertical efforts of ministries of health and other partners in the Global Polio Eradication Initiative. The CGPP has developed innovative strategies to detect cases using community-based surveillance, promoted independent campaign monitoring, established cross-border initiatives, and developed a strong and creative cadre of community mobilizers to track missed children and deliver behavior change education. Many of the innovations and approaches that the CGPP helped to develop are now being replicated by governments and international agencies to tackle other public health priorities in underserved and marginalized communities around the world. This article is the first in a series of articles describing the work of the CGPP. Because the article describes the work of more than 40 NGOs in 11 countries over 20 years, it provides only an overview, leaving many important details and variations of the CGPP's work to be described elsewhere, including in other articles included in this series.

Community Involvement in Health Systems Strengthening to Improve Global Health Outcomes: A Review of Guidelines and Potential Roles.

Definitions of health systems strengthening (HSS) have been limited in their inclusion of communities, despite evidence that community involvement improves program effectiveness for many health interventions. We review 15 frameworks for HSS, highlighting how communities are represented and find few delineated roles for community members or organizations. This review raises the need for a cohesive definition of community involvement in HSS and well-described activities that communities can play in the process. We discuss how communities can engage with HSS in four different areas-planning and priority-setting; program implementation; monitoring, evaluation, and quality improvement; and advocacy-and how these activities could be better incorporated into key HSS frameworks. We argue for more carefully designed interactions between health systems policies and structures, planned health systems improvements, and local communities. These interactions should consider local community inputs, strengths, cultural and social assets, as well as limitations in and opportunities for increasing capacity for better health outcomes.

Institutionalizing community-focused maternal, newborn, and child health strategies to strengthen health systems: A new framework for the Sustainable Development Goal era.

BACKGROUND: Stronger health systems, with an emphasis on community-based primary health care, are required to help accelerate the pace of ending preventable maternal and child deaths as well as contribute to the achievement of the Sustainable Development Goals (SDGs). The success of the SDGs will require unprecedented coordination across sectors, including partnerships between public, private, and non-governmental organizations (NGOs). To date, little attention has been paid to the distinct ways in which NGOs (both international and local) can partner with existing national government health systems to institutionalize community health strategies. DISCUSSION: In this paper, we propose a new conceptual framework that depicts three primary pathways through which NGOs can contribute to the institutionalization of community-focused maternal, newborn, and child health (MNCH) strategies to strengthen health systems at the district, national or global level. To illustrate the practical application of these three pathways, we present six illustrative cases from multiple NGOs and discuss the primary drivers of institutional change. In the first pathway, "learning for leverage," NGOs demonstrate the effectiveness of new innovations that can stimulate changes in the health system through adaptation of research into policy and practice. In the second pathway, "thought leadership," NGOs disseminate lessons learned to public and private partners through training, information sharing and collaborative learning. In the third pathway, "joint venturing," NGOs work in partnership with the government health system to demonstrate the efficacy of a project and use their collective voice to help guide decision-makers. In addition to these pathways, we present six key drivers that are critical for successful institutionalization: strategic responsiveness to national health priorities, partnership with policymakers and other stakeholders, community ownership and involvement, monitoring and use of data, diversification of financial resources, and longevity of efforts. CONCLUSION: With additional research, we propose that this framework can contribute to program planning and policy making of donors, governments, and the NGO community in the institutionalization of community health strategies.

A new resource for developing and strengthening large-scale community health worker programs.

Large-scale community health worker programs are now growing in importance around the world in response to the resurgence of interest and growing evidence of the importance of community-based primary health care for improving the health of populations in resource-constrained, high-mortality settings. These programs, because of their scale and operational challenges, merit special consideration by the global health community, national policy-makers, and program implementers. A new online resource is now available to assist in that effort: Developing and Strengthening Community Health Worker Programs at Scale: A Reference Guide and Case Studies for Program Managers and Policymakers ( http://www.mchip.net/CHWReferenceGuide ). This CHW Reference Guide is the product of 27 different collaborators who, collectively, have a formidable breadth and depth of experience and knowledge about CHW programming around the world. It provides a thoughtful discussion about the many operational issues that large-scale CHW programs need to address as they undergo the process of development, expansion or strengthening. Detailed case studies of 12 national CHW programs are included in the Appendix-the most current and complete cases studies as a group that are currently available. Future articles in this journal will highlight many of the themes in the CHW Reference Guide and provide an update of recent advances and experiences. These articles will serve, we hope, to (1) increase awareness about the CHW Reference Guide and its usefulness and (2) connect a broader audience to the critical importance of strengthening large-scale CHW programs for the health benefits that they can bring to underserved populations around the world.

Community-based intervention packages facilitated by NGOs demonstrate plausible evidence for child mortality impact.

INTRODUCTION: Evidence exists that community-based intervention packages can have substantial child and newborn mortality impact, and may help more countries meet Millennium Development Goal 4 (MDG 4) targets. A non-governmental organization (NGO) project using such programming in Mozambique documented an annual decline in under-five mortality rate (U5MR) of 9.3% in a province in which Demographic and Health Survey (DHS) data showed a 4.2% U5MR decline during the same period. To test the generalizability of this finding, the same analysis was applied to a group of projects funded by the US Agency for International Development. Projects supported implementation of community-based intervention packages aimed at increasing use of health services while improving preventive and home-care practices for children under five. METHODS: All projects collect baseline and endline population coverage data for key child health interventions. Twelve projects fitted the inclusion criteria. U5MR decline was estimated by modelling these coverage changes in the Lives Saved Tool (LiST) and comparing with concurrent measured DHS mortality data. RESULTS: Average coverage changes for all interventions exceeded average concurrent trends. When population coverage changes were modelled in LiST, they were estimated to give a child mortality improvement in the project area that exceeded concurrent secular trend in the subnational DHS region in 11 of 12 cases. The average improvement in modelled U5MR (5.8%) was more than twice the concurrent directly measured average decline (2.5%). CONCLUSIONS: NGO projects implementing community-based intervention packages appear to be effective in reducing child mortality in diverse settings. There is plausible evidence that they raised coverage for a variety of high-impact interventions and improved U5MR by more than twice the concurrent secular trend. All projects used community-based strategies that achieved frequent interpersonal contact for health behaviour change. Further study of the effectiveness and scalability of similar packages should be part of the effort to accelerate progress towards MDG 4.

A methodological approach and framework for sustainability assessment in NGO-implemented primary health care programs.

An estimated 10.8 million children under 5 continue to die each year in developing countries from causes easily treatable or preventable. Non governmental organizations (NGOs) are frontline implementers of low-cost and effective child health interventions, but their progress toward sustainable child health gains is a challenge to evaluate. This paper presents the Child Survival Sustainability Assessment (CSSA) methodology--a framework and process--to map progress towards sustainable child health from the community level and upward. The CSSA was developed with NGOs through a participatory process of research and dialogue. Commitment to sustainability requires a systematic and systemic consideration of human, social and organizational processes beyond a purely biomedical perspective. The CSSA is organized around three interrelated dimensions of evaluation: (1) health and health services; (2) capacity and viability of local organizations; (3) capacity of the community in its social ecological context. The CSSA uses a participatory, action-planning process, engaging a 'local system' of stakeholders in the contextual definition of objectives and indicators. Improved conditions measured in the three dimensions correspond to progress toward a sustainable health situation for the population. This framework opens new opportunities for evaluation and research design and places sustainability at the center of primary health care programming.

An implementation framework for household and community integrated management of childhood illness.

This paper describes the development and recent history of the third component of the Integrated Management of Childhood Illness (IMCI) strategy, improving household and community practices (HH/C IMCI). An implementation framework for this third component, developed through review of experiences of non-governmental organizations (NGOs) working in community-based child health and nutrition programmes, is then presented. This Framework responds to demand from NGOs and their partners for a description of the different categories of community-level activities necessary for the implementation of a comprehensive child health and nutrition programme. These categories of activities facilitate the systematic cataloguing, synthesis and coordination of organizational activities and experience. It also serves as a reference tool for improving communication of related community child health activities, and a guide for designing appropriate behaviour change strategies. The Framework was endorsed by participants in an international workshop held in Baltimore, Maryland in January 2001, and specified three linked elements that are integral to HH/C IMCI, supported by a multi-sectoral platform that addresses constraints communities face in adopting practices that promote health and nutrition. The three programmatic Elements critical to HH/C IMCI programmes are (1). improving partnerships between health facilities or services and the communities they serve; (2). increasing appropriate and accessible care and information from community-based providers; and (3). integrating promotion of key family practices critical for child health and nutrition. The Framework presented in this paper is an ideal tool for describing, sharing and coordinating efforts in the field, and is purposely descriptive rather than prescriptive.
