Randomized trial of targeted performance feedback to facilitate quality improvement in acute myocardial infarction care

Background-Efforts to improve quality of care for patients with acute myocardial infarction (AMI) are a national priority. To date, there have been few studies that have prospectively evaluated hospital quality improvement (QI) interventions. Methods and Results-Using hospitals in the National Cardiovascular Data Registry (NCDR) ACTION Registry-GWTG, a cluster randomized trial of the effectiveness of targeted performance feedback to facilitate process improvement for AMI care will be conducted. ACTION Registry-GWTG hospitals with a minimum of 50 AMI patients per 2 quarters are eligible for randomization. The control arm receives standard performance feedback reports, and the intervention arm receives standard performance feedback reports in addition to a supplemental report on the "top 3" centrally identified, hospital-specific performance gaps. The primary outcome will be improvement in a composite of all metrics, and the secondary outcome will be improvement in the targeted metrics. At study inception in January 2009, 149 sites were randomized: 76 to the intervention arm, and 73 to the control arm. Intervention and control sites were well balanced in terms of baseline performance, center characteristics, and AMI volume (-70 patients per quarter). The intervention phase will continue for 5 feedback cycles, each containing 2 quarters of data feedback over 18 months. A final trial outcome report will follow. Conclusions-This randomized trial will evaluate a novel hospital-level QI intervention of targeted performance feedback for AMI, thereby demonstrating the effective use of national registries for QI and furthering our understanding of effective QI methods.
