Current status and future direction of antimicrobial stewardship programs and antibiotic prescribing in primary care hospitals in Zambia.

Antimicrobial Stewardship Programs (ASPs) intended to optimize antibiotic use will be more effective if informed by the current status and patterns of antibiotic utilisation. In Zambia's primary healthcare (PHC) settings, data on ASPs and antibiotic utilisation were inadequate to guide improvements. As a first step, this study assessed antibiotic prescribing and ASP core elements among PHC first-level hospitals (FLHs) in Zambia. A point prevalence survey was conducted at the five FLHs in Lusaka using the Global-PPS® protocol. Hospital ASP core elements evaluated included hospital leadership commitment, accountability, pharmacy expertise, action, tracking, reporting, and education. Antibiotic use prevalence was 79.8% (146/183). A total of 220 antibiotic prescription encounters were recorded among inpatients, with ceftriaxone (J01DD04, Watch) being the most (50.0%) prescribed. Over 90.0% (202) of the antibiotic prescriptions targeted suspected community-acquired infections, but only 36.8% (81) were compliant with national treatment guidelines. ASP core element implementation was 36.0% (16.2/45), with only two hospitals achieving over 50.0%. The most deficient core elements were accountability, action, tracking, and reporting. ASP implementation in Zambia's FLHs providing PHC was sub-optimal, with high antibiotic prescribing rates, frequent use of broad-spectrum Watch group antibiotics, and low compliance with national treatment guidelines. As key ways forward, ASPs in Zambia's PHC require strengthening by adapting the WHO AWaRe recommendations and improving accountability, actions, tracking, and reporting antibiotic use to improve stewardship practice and reduce AMR.
