Antibiotic Prescribing Recommendations in COVID-19: A Systematic Survey

Abstract

Background: COVID-19 and antimicrobial resistance (AMR) are two intersecting public health crises. Antimicrobial overuse in patients with COVID-19 threatens to contribute to the growing threat of AMR. Guidelines are fundamental in encouraging antimicrobial stewardship. We sought to assess the quality of antibiotic prescribing guidelines and recommendations in the context of COVID-19, and if these guidelines incorporate principles of antimicrobial stewardship. Methods: We performed a systematic survey which included a search using the concepts “antibiotic/antimicrobial” in September to November 2022 of the eCOVID-19 living map of recommendations (RecMap) which aggregates and summarizes guidelines across a range of international sources and all languages. Guidelines providing explicit recommendations regarding antibacterial use in COVID-19 from any jurisdiction were eligible for inclusion. Guideline and recommendation quality were assessed using the AGREE II and AGREE-REX instruments, respectively. We extracted guideline characteristics including panel representation and the presence or absence of explicit statements related to antimicrobial stewardship (i.e., judicious antibiotic use, antimicrobial resistance or adverse effects as a consequence of antibiotic use). We used logistic regression to evaluate the relationship between guideline characteristics including quality and incorporation of antimicrobial stewardship principles. Results: Twenty-eight guidelines with 63 antibiotic prescribing recommendations were included. Recommendations focused on antibiotic initiation (n=52, 83%) and less commonly antibiotic selection (n=13, 21%), and duration of therapy (n=15, 24%). Guideline and recommendation quality varied widely. Twenty (71%) guidelines incorporated at least one concept relating to antimicrobial stewardship. Including infectious diseases expertise on the guideline panel (OR 9.44, 97.5%CI: 1.09 to 81.59) and AGREE-REX score (OR 3.26, 97.5%CI: 1.14 to 9.31 per 10% increase in overall score) were associated with a higher odds of guidelines addressing antimicrobial stewardship. Conclusion: There is an opportunity to improve antibiotic prescribing guidelines in terms of both quality and incorporation of antimicrobial stewardship principles. These findings can help guideline developers better address antibiotic stewardship in future recommendations beyond COVID-19.
