Evidence-Based Strategies in Using Persuasive Interventions to Optimize Antimicrobial Use in Healthcare: a Narrative Review

A rise in antimicrobial resistance, seen especially since 2000, is in part caused by indiscriminate antimicrobial use. Varied types of persuasive interventions aimed to optimize antimicrobial use have been tried with varying success. Our review seeks to identify and assess factors associated with the successful implementation of persuasive interventions. We searched five databases (MEDLINE, EMBASE, The Cochrane Library, PsycINFO, and ERIC) to identify critical studies published between 2000 and December 2018 of interventions employing audit and feedback, education through meetings, academic detailing, reminders, and patient, family, or public education. Outcome measures of interest were any means to measure antimicrobial use. We included 26 articles in our analysis. Seventeen examined multimodal interventions and the most common was audit and feedback and meeting (four studies). Nine examined single interventions and the most common was audit and feedback (five studies). Our findings inform four evidence-based strategies to enable healthcare administrators, clinicians, and researchers to make informed choices when planning and designing an antimicrobial stewardship program: (1) implement a combination of persuasive interventions from both groups: audit and feedback, academic detailing, or patient, family, or provider education; and meeting or reminders, (2) design interventions that last one year or longer; post-intervention, assess the intervention’s long-term effects for at least another one year, (3) conduct quality improvement projects examining persuasive interventions if the prescribing database provides adequate diagnosis information, and most importantly, (4) make patient, family, or provider education an integral component of multimodal intervention.
