The Applicability of AWaRe-Based Antibiotic Quality Indicators to Assess the Appropriateness of Antibiotic Prescribing in Primary Healthcare in South Africa: A Multicentre Point Prevalence Study and Implications for the Future

Abstract

Background/Objectives: Inappropriate antibiotic prescribing in primary healthcare (PHC) contributes to bacterial antimicrobial resistance (AMR). Antibiotic stewardship, including measuring the appropriateness of antibiotic prescribing using quality indicators, is a priority in PHC where most antibiotics are used. Using previously developed WHO AWaRe classification-based quality indicators, we aim to test the clinimetric properties of 13 acute respiratory tract infection (RTI) quality indicators and qualitatively explore factors influencing PHC antibiotic prescribing in South Africa. Methods: We conducted a mixed-methods exploratory feasibility study using point prevalence surveys (PPSs) with clinimetric assessment and prescriber interviews. PPSs were conducted at four PHC facilities in Gauteng province that had taken part in previous PPS studies, alongside face-to-face interviews with PHC personnel. Results: In total, 52/52 (100%) RTI patients received antibiotics. Four (30.8%) indicators achieved scores above 85%, while six (46.2%) scored below 50%. All indicators had applicability scores ≥10%. Twelve (92.3%) indicators had a measurability score of 100%, while one (7.7%) had a measurability score <75%. Twelve (92.3%) indicators met all predefined acceptable scores for applicability and measurability. No participant knew of the WHO’s AWaRe classification and none had specific training on antibiotic prescribing and AMR. They also had no antibiotic stewardship programmes (ASPs) or specific antibiotic-prescribing guidelines at their facilities. Key factors affecting antibiotic prescribing included shortages, patient expectations and fear of complications. Conclusions: The indicators demonstrated acceptable clinimetric properties in South Africa. Robust locally validated indicators, combined with ASPs promoting the AWaRe classification, are imperative for accurate assessment and improvement of antibiotic prescribing.
