Empanelment is a foundational strategy for building or improving primary health care systems and critical pathway achieving effective universal coverage. However, there little international guidance defining empanelment understanding how to implement in low- middle-income countries. To fill this gap, multi-country collaborative within the Joint Learning Network Universal Health Coverage developed overview, proposing people-centered definition of that reflects responsibility proactively...
