Effectiveness of training supervisors to improve reproductive health quality of care: a cluster-randomized trial in Kenya.

Health facility supervisors are in a position to increase motivation, manage resources, facilitate communication, increase accountability and conduct outreach. This study evaluated the effectiveness of a training intervention for on-site, in-charge reproductive health supervisors in Kenya using an experimental design with pre- and post-test measures in 60 health facilities. Cost information and data from supervisors, providers, clients and facilities were collected. Regression models with the generalized estimating equation approach were used to test differences between study groups and over time, accounting for clustering and matching. Total accounting costs per person trained were calculated. The intervention resulted in significant improvements in quality of care at the supervisor, provider and client-provider interaction levels. Indicators of improvements in the facility environment and client satisfaction were not apparent. The costs of delivering the supervision training intervention totalled US$2113 per supervisor trained. In making decisions about whether to expand the intervention, the costs of this intervention should be compared with other interventions designed to improve quality.
