Pattern of antimicrobial prescription in Africa: a systematic review of point prevalence surveys
Abstract
Introduction: inappropriate use of antimicrobials is a cause for concern and contributes to the global antimicrobial resistance crises especially in Africa. This review aims to summarize the available evidence on the point prevalence and pattern of antimicrobial and/or antibiotic prescription in Africa.
Methods: this review was carried out between April and September 2021 and identified published studies up until March 2021 on the point prevalence of antibiotic and/or antimicrobial use in Africa. Sources searched were OVID, PubMed, EMBASE, CINAHL, Web of Science, Google Scholar, Google, and African Journal Online (AJOL). Observational studies that reported prevalence published in English language were included. Covidence systematic review software was used for this review. A form for data extraction using domains culled from the Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) was developed on Covidence. Screening of studies for eligibility was done independently by two reviewers. Critical Appraisal tool for use in Joanna Briggs Institute (JBI) Systematic Reviews for prevalence studies was used for quality appraisal.
Results: a total of 17 studies that met the inclusion criteria were included in the review. The overall prevalence of antimicrobial/antibiotic use among inpatients in these studies ranged from 40.7% to 97.6%. The median antimicrobial/antibiotic use was 61.3 [IQR= 45.5-72.1]. The highest use of antimicrobials was reported among studies from Nigeria with a prevalence of 97.6%. The most prescribed antibiotics were the beta-lactam penicillin (Amoxicillin, clavulanic acid) (86.9%), and third generation cephalosporins (55.0%). There was general preference for parenteral route of administration of the antimicrobial agents (40-70%). Use for community acquired infections (28.0-79.5%) was the main reason for use. Majority of the prophylactic use of antimicrobial agents was for surgical prophylaxis.
Conclusion: the high prevalence of antimicrobial use in Africa reinforces the need for continued surveillance and concerted efforts to institutionalize and support antimicrobial stewardship for prescribers in health institutions in the African region.
