Community health workers: An opportunity for reverse innovation

摘要

Prabhjot Singh and Jeffrey Sachs' Viewpoint (July 27, p 363) describes well the rationale for scaling-up a subsystem of community health workers (CHWs) in sub-Saharan Africa and the progress to date.It is well recognised that CHWs can bring multiple benefits to individuals and populations, and improve efficiency and equity within health systems. WHO now recommends an expanded CHW role. What is less well recognised is that such a system is applicable to all WHO member states.
