S1 Dataset for "Associations between health systems capacity and mother-to-child HIV prevention program outcomes in Zambia"

We investigated the association between health system capacity and use of prevention of mother-to-child HIV transmission (PMTCT) services in Zambia. We analyzed data from two studies conducted in rural and semi-urban Lusaka Province in 2014–2015.

Health system capacity, our primary exposure, was measured with a validated balanced scorecard approach. Based on WHO building blocks for health systems strengthening, we derived overall and domain-specific facility scores (range: 0–100), with higher scores indicating greater capacity. Our outcome, community-level maternal antiretroviral drug use at 12 months postpartum, was measured via self-report in a large cohort study evaluating PMTCT program impact.
