Robust research demonstrates CHWs improve access to care, reduce maternal, newborn, and child mortality, improve clinical outcomes for chronic diseases, and prevent disease outbreaks [3]. But there remains an important opportunity to improve the status quo approach to implementing national-scale CHW programs. While ample, high-quality evidence exists that small-scale CHW programs can reduce morbidity and mortality [4], three studies of CHW scale-up conducted in Burkina Faso, Ethiopia, and Malawi in 2016 documented limited access, quality, and mortality impact [5-7]. The impact of these programs, and those of the dozens of other countries currently revamping their own national CHW programs, could be optimized if the most recent evidence and global best practices were incorporated into design and implementation [8-11]. To support the operationalization of quality CHW program design and implementation, USAID, UNICEF, the Community Health Impact Coalition, and Initiatives Inc. have updated and adapted the Community Health Worker Assessment and Improvement Matrix (CHW AIM) Program Functionality Matrix [12]. This tool can be used to identify design and implementation gaps in both small- and national-scale CHW programs, and close gaps in policy and practice…..more
