Non-Inferiority of Peer Comparison Interventions

"Peer comparison was an email-based intervention. Clinicians were ranked from highest to lowest inappropriate prescribing rate within each region using EHR data. Clinicians with the lowest inappropriate prescribing rates (the top-performing decile) were told via monthly email they were Top Performers. The remaining clinicians were told that they were Not a Top Performer in an email that included the number and proportion of antibiotic prescriptions they wrote for antibiotic-inappropriate acute respiratory tract infections, compared with the proportion written by top performers."
