Alarming Antimicrobial Prescribing Patterns at a Tertiary Hospital in Nigeria: A Point Prevalence Survey using the Global-PPS Protocol.

Background: Antimicrobial resistance is a critical threat in Nigeria, where inappropriate prescribing remains one of the major drivers. This study evaluated antimicrobial use patterns at Usmanu Danfodiyo University Teaching Hospital (UDUTH) using the Global Point Prevalence Survey methodology. Methodology: A cross-sectional survey was conducted October 21-25, 2024 across all inpatient wards using standardized GPPS protocols. Data collectors received virtual training through the Fleming Fund project.
