Global Experience of Community Health Workers for Delivery of Health Related Millennium Development Goals: A Systematic Review, Country Case Studies, and Recommendations for Integration into National Health Systems

Participation of community health workers (CHWs) in the provision of primary health care has been experienced all over the world for several decades, and there is an amount of evidence showing that they can add significantly to the efforts of improving the health of the population, particularly in those settings with the highest shortage of motivated and capable health professionals. With the overall aim of identifying CHWs programs with positive impact on Millennium Development Goals (MDGs) related to health or otherwise, a global systematic review was undertaken of such interventions, as well as eight in-depth country case studies in Sub-Saharan Africa (Ethiopia Mozambique and Uganda), South East Asia (Bangladesh, Pakistan and Thailand) and Latin America (Brazil and Haiti). The focus was on key aspects of these programs, encompassing typology of CHWs, selection, training, supervision, standards for evaluation and certification, deployment pat­terns, in-service training, performance, and impact assessment.
