SETTING: The ED of an urban Level-I adult trauma center with existing CDS for CTPE. PARTICIPANTS: All attending physicians were stratified into quartiles by 2012 CTPE use and randomized to receive feedback reporting or not. INTERVENTION: Quarterly performance feedback reports consisting of individual and anonymized group data on EBG adherence (using the Wells criteria), CTPE use (CTPEs per 1,000 patients), and yield (percentage of CTPEs positive for PE) beginning January 2013.
