Contributions of a community health worker program in improving district health system performance in South Africa, using routine health service variables in a quasi-experimental study design

Large-scale, sustained and comprehensive community health worker programs adequately covering populations contributed to improved urban district health system performance in Ekurhuleni, demonstrating their effectiveness. This was explored through improvements in health system performance over time. These findings, using routine health service variables, have policy implications for financial and other resource allocations in health districts in low- and middle-income countries.
