<p>We defined ‘baseline’ as January-April 2022, ‘midline’ as May-July 2022 and ‘endline’ as August-October 2022. We reviewed PrEP registers at baseline to establish the number of high-risk pregnant and breastfeeding women initiated on PrEP. A quality improvement team was formed and trained on the Plan-Do-Study-Act approach. Together with the team, we analysed the root causes of low PrEP initiation among high-risk pregnant and breastfeeding women using fishbone analysis and implemented interventions. To evaluate the intervention success, we reviewed PrEP data for high-risk pregnant and breastfeeding women at midline and endline and assessed changes from baseline as proportions of targeted women who were initiated on PrEP using chi-square test.</p>
