A Regional Approach to Strengthening Implementation of Sustainable Antimicrobial Stewardship Programs in Five countries in East, Central, and Southern Africa

Background: Antimicrobial stewardship (AMS) programs optimize use of antimicrobi-als and reduce antimicrobial resistance (AMR). This study evaluated implementation of AMS programs in Africa using a harmonized regional approach. Methods: This was an exploratory cross-sectional study across five countries involving 32 hospitals using adapted Periodic National and Hospitals Assessment Tool in WHO policy guidance on integrated AMS activities in human health. Results: This study found baseline scores for AMS core elements ranging from 34% to 79% and improved to 58% to 92% at the end line. At baseline, DTC functionality in updating facility-specific medicines and medical devices ranged from 58% to 100% and ranged from 79 to 100% at endline. Classifying antibiotics by WHO AWaRe classification ranged from 33% to 83% at baseline and 64% to 100% at endline. Leadership commitment scores were 47% at baseline and 66% at endline. Education and training scores were 42% and 63% at baseline and end-line respectively. Reporting and feedback was 34% at baseline and 58% at endline. Conclusions: Our study showed that understanding context and standardizing regional stewardship approaches enhanced cross-country learning and improved AMS implementation. Although challenges in LMICs are similar, they vary by country and can be addressed by strengthening AMS regulatory frameworks and surveillance systems.
