Background: Nigeria joined the global community in monitoring antimicrobial prescribing practices since 2015. Results of individual hospital Global Point Prevalence Survey (Global-PPS) have stimulated efforts at instituting hospital-based antimicrobial stewardship (AMS) programmes. We report the trends of antimicrobial prescribing rates and quality indicators for 3 surveillance periods; 2015, 2017 and 2018.
Methodology: The web-based Global-PPS for surveillance of antimicrobial use in hospitals (www.global-pps.com) was completed by each participating hospital site for all inpatients receiving antimicrobials on a selected day in 2015, 2017 and 2018. Data included details on antimicrobial agents, reasons and indications for treatment and a set of quality prescribing indicators. Data were validated by the web-based data management system of University of Antwerp, exported into Microsoft Excel and analyzed with EPI INFO version 7.2.
Results: Thirteen hospitals participated in the survey involving a total of 5,174 inpatients. Mean weighted overall antimicrobial prescribing prevalence was 70.7% which declined over the years from 71.7% in 2015 to 59.1% in 2018 (p<0 p=0.6803), p=0.008).> Conclusions: The survey showed reduction in the overall antimicrobial prescribing rate especially in hospitals that had introduced AMS programmes. Among the quality prescribing indicators, documentation of post prescription review date showed improvement. The Global-PPS serves as a cost effective, flexible and user-friendly tool in instituting AMS programmes in hospitals.
