Integrating community health workers to sustain malaria services in the Greater Mekong Subregion: Findings from implementer case studies

Many countries in the Asia Pacific rely on community health workers (CHWs) to care for various health needs. In the Greater Mekong Subregion (GMS), malaria CHWs have been an essential component of malaria elimination. Yet as the malaria burden declines, the role of malaria CHWs in local health systems and communities is changing. There is a need to expand malaria CHW roles to take on the provision of health services beyond malaria. This study sought to understand the process and experience of this role expansion including implementation, financing, policy, and sustainability within the Asia Pacific region. We documented malaria CHW programs that included health services in addition to malaria. We conducted 21 key-stakeholder interviews from thirteen programs in eight countries throughout the Asia Pacific region virtually in English and findings were analyzed using rapid-matrix analysis. Participants were recruited by an online landscaping survey, with an inclusion criterion of five + years' work experience and English speaking. Governments ran five of the thirteen programs; six were international non-governmental organizations (INGOs), and two were academic. Senior staff from programs that have expanded roles of malaria CHWs or integrated CHW programs explained expansion processes, challenges, and opportunities. We found that integration can occur in multiple program domains and does not necessarily occur in all domains simultaneously. We identified entry points for role expansion: integrated policy and financing, planning, assessments, and research. Operational entry points included the selection, training, motivation, management, supervision, and monitoring of CHWs. Enabling factors included decentralized management structures, health system linkages, commodity provision and referral procedures, and community engagement. While there is not a linear or unique path towards integration, we provide considerations for the policy level, practical implementation steps, and enabling factors for countries in the GMS to consider as they move towards sustainable, integrated malaria CHWs.
