The use of small group based educational interventions in General Practice to improve antimicrobial prescribing behaviours: a mixed methods systematic review protocol

Background Inappropriate use of antimicrobial agents in healthcare settings is one area that has received attention as a possible route to mitigate the threat of antimicrobial resistance. Globally, the highest consumption of antimicrobials in human healthcare originates from prescriptions in Primary Care. Strategies to increase appropriate antibiotic prescribing, which can mean not prescribing an antibiotic e.g. cases of viral infection, have been developed and evaluated. This systematic review aims to review the literature of studies of group based in person educational interventions designed to increase appropriate antibiotic prescribing behaviours in General Practice settings. Methods EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, MEDLINE and PsycINFO will be systematically searched from inception until February 2024 for primary studies of group based educational interventions designed to improve the antimicrobial prescribing behaviours in General Practice. Qualitative, quantitative and mixed methods studies that report on the phenomenon of interest will be included. All identified articles will be double screened at title and abstract level. One reviewer will then screen all included studies at full text level, extract the data, code the intervention and perform risk of bias assessment with a second reviewer performing verification of a randomly selected 20% of the articles. We will use an integrated approach to mixed method systematic reviews and will perform a narrative, or if possible quantitative, synthesis. Discussion The review will identify and assess the efficacy and / or effectiveness of small group based educational interventions designed to improve the antibiotic prescribing behaviours of General Practitioners. By using a mixed methods approach we aim to identify the salient content of the included interventions and the perspectives of participants on the content and delivery of the included interventions. We will use the findings to inform the design and content of a small group educational intervention for GP registrars.
