Awareness of inappropriate use related to antimicrobial resistance among medical doctors by country economic status: A systematic review

BACKGROUND: Antimicrobial resistance (AMR) is promoted by inappropriate use and is a greater burden for low to middle income countries (LMIC) than high income countries (HIC). OBJECTIVE: This systematic review aimed to compare the awareness of inappropriate use related to AMR among medical doctors from LMIC and HIC using published knowledge, attitude and practice (KAP) studies. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, sequential systematic literature search of PubMed and Web of Science databases for articles published since inception up to June 1, 2022 for KAP studies involving medical doctors. Using fifteen KAP items related to promoting AMR, data on proportion of participants responding affirmatively was extracted and reported using means, ranges and 95% confidence intervals (CI). RESULTS: Forty-two studies met the inclusion criteria and involved 13,089 medical doctors from 11HIC and 21LMIC. All were cross-sectional studies, 71.4% involved non-probability sampling and 78.6% were of satisfactory quality. Knowledge items showed mean proportion of more medical doctors responding correctly. Similar affirmation trends were observed for attitude and prescribing practice items. Awareness appeared similar between medical doctors of the economic groups, except for a greater interest in training for LMIC (95.4%; 95%CI 93.0%, 97.9%) versus HIC (81.7%; 95%CI 65.6%, 97.9%). Countries with poor proportions were identified in both economic groups. CONCLUSION: For identified studies, trends suggest good awareness among medical doctors of the known inappropriate use and perceived threat of AMR, as well as prescribing practices to reduce the risk of AMR. Trends were similar across HIC and LMIC; however, countries with evidence of poor awareness exist in both economic groups.
