REACHOUT is a multi-country study in Asia and Africa that aims to improve quality, efficiency, and effectiveness of close-to-community health providers through quality improvement initiatives. The study uses a 5-year approach involving context analysis, quality improvement interventions, and embedding improvements into health systems. This includes building research capacity, identifying how context and policies influence health systems, developing and testing interventions, and informing evidence-based policymaking. Key areas of focus include supervision, community engagement, referral systems, and coordination among providers. The goal is to shift quality improvement efforts from researcher-led projects to being district-led.
