Impact of a Simple Automated Best Practice Alert (BPA) on Quantity and Quality of In-hospital Antibiotic Use in a Tertiary and Three Secondary Hospitals

The goal of the stepped-wedge cluster-randomized trial is to assess the impact of an antimicrobial stewardship intervention: a simple, automated Best Practice Alert (BPA) that reminds prescribers to reevaluate antibiotic therapy after 72 hours (or 24 hours for prophylaxis), in accordance with guideline recommendations. The primary hypothesis is that this simple BPA reduces antibiotic use in terms of quantity (amount and duration) and quality (spectrum breadth), measured by days of antibiotic spectrum coverage at the patient level (primary outcome), as well as at both patient and cluster levels using various metrics of antibiotic use. The trial will introduce the BPA in a stepwise manner, with all wards implementing it by the end. It will compare the intervention period to the baseline (pre-intervention) and control periods.
