Abstract

Objectives:
To synthesize current evidence for the effectiveness of interventions to ensure the timely review of antibiotics in acute care hospitals.
Methods:
Five databases were searched from 1 January 2015 to 8 March 2019 for studies in English, focused on the timely review of antibiotics in acute care hospitals. Randomized controlled trials, non-randomized studies, case–control and cohort study designs were eligible. Intervention strategies were categorized according to the Cochrane Effective Practice and Organisation of Care taxonomy of health interventions, then mapped to the intervention functions of the behaviour change wheel.
Results:
Fourteen studies were included. Most studies (11 out of 14) were conducted in single sites. Nine out of 14 reported intervention delivery by more than one healthcare professional. Physicians were the main targets of interventions in all studies. Thirteen out of 14 studies tested interventions comprising more than one strategy. The three most commonly utilized strategies within interventions were clinical practice guidelines, audit and feedback, and educational materials. Only one study employed theory in intervention evaluation. Reported interventions led to timely review and switch of IV antibiotic therapy, and shortened durations of overall antibiotic therapy.
Conclusions:
Interventions to improve the review of antibiotics were found to be effective in the short to medium term, with limited evidence of long-term sustainability in multiple sites. Future research may benefit from the application of theory to intervention design and detailed specifications of interventions to aid their easy replication and implementation in different contexts.
