Data were collected as part of the baseline for a cluster randomized controlled trial in Kisumu County, Western Kenya, evaluating a social accountability–based quality improvement intervention designed to strengthen contraceptive service delivery through citizen feedback, public monitoring, and dialogue. Baseline data were gathered from all 137 public-sector facilities between May and October 2022 using structured unannounced visits and provider interviews. A very short facility audit was also conducted in between unannounced visits and provider interviews.
