RESUMEN
BACKGROUND: The Health Extension Program (HEP) was introduced in 2003 to extend primary health care services by institutionalizing the former volunteer-based village health services.However, this program is not comprehensively evaluated.MATERIALS AND METHODS: The 2019 comprehensive national assessment of HEP involved (1) assessment through quantitative and qualitative primary data, (2) a thorough systematic review of the HEP literature, and (3) a synthesis of evidence from the two sources. The assessment included household survey(n=7122), a survey of health extension workers (HEWs) (n=584)_, and an assessment of health posts (HPs)(n=343) and their supervising health centers (HCs)(n=179)from 62 randomly selected woredas. As part of the comprehensive assessment.OUTPUT AND RESULTS: The outputs were (a) full and abridged reports, (b) 40 posters, (c) seven published, three under review scientific papers and (d) seven papers in this special issue. During the one-year period preceding the study, 54.8% of women, 32.1% of men, and 21.9% of female youths had at least a one-time interaction with HEWs. HPs and HEWs were universally available. There were critical gaps in the skills and motivation of HEWs and fulfillment of HP standards: 57.3% of HEWs were certified, average satisfaction score of HEWs was 48.6%, and 5.4% of HPs fulfilled equipment standards. CONCLUSIONS: The findings informed policy and program decisions of the Ministry of Health, including the design of the HEP Optimization Roadmap 20202035 and the development Health Sector Transformation Plan II.
