Brief summary

This study tests strategies for improving PrEP implementation in maternal and child health clinics using an interrupted time series.

Detailed description

This study aims to improve integrated delivery of PrEP to women seeking health services in maternal and child health clinics by piloting and evaluating four strategies or bundles of strategies for optimized PrEP delivery. Strategies to be tested include three packages of strategies identified by stakeholders.

Interventions

There were three bundles of strategies tested determined based on the qualitative information gathered in Aim 1 by stakeholders

Intervention model description

A difference-in-difference design will be used; this is a quasi-experimental design that compares data before an intervention is introduced to data after the intervention is introduced and compares that with the expected change before and after in comparison clinics. Three rounds of difference-in-differences tests will be used to evaluate three PrEP optimization interventions, identified by stakeholders based on qualitative information. Each of the three rounds will include 4 facilities receiving the intervention and 4 facilities serving as an ongoing concurrent comparator group; these 4 facilities will not receive any of the packages of interventions, but will undergo the same data collection procedures.

PrEP Adherence

Proportion of women who have \>80 percent adherence to PrEP by pill count among those initially prescribed PrEP

Time frame: 6 months

Population: During preparatory activities for data collection, it was determined that it was not feasible to extract patient adherence information,; this outcome was neither collected nor compared. It was not feasible to extract patient adherence information because routine program data at each facility different substantially in how it quantified adherence to PrEP; it was not possible, nor meaningful to collect or analyze these data.

PrEP Continuation

PrEP Efficiency

Time frame: 6 months

Population: During preparatory activities for data collection, it was determined that it was not feasible to collect efficiency. This outcome was neither collected nor compared. It was not feasible to quantify efficiency in the way in which we originally envisioned due to the heterogeneity between sites and within sites on how service provision was organized and delivered.
