•
1 like•574 views
This document summarizes an assessment of data sources and quality used in South Africa's District Health Barometer. It finds that census and vital statistics data are generally adequate, while population surveys, health records, service records, and resource records are only present but not adequate. Health records in particular have problems of being burdensome, incomplete, of poor quality, and having inadequate staffing. The document reviews challenges with health data management and discusses specific issues with HIV prevalence data sources and vital statistics reporting.
