Targeted versus standard feedback: results from a randomized quality improvement trial.

BACKGROUND: Quality improvement is central to improving the care of patients with cardiovascular disease; however, the optimum type of data feedback to support such efforts is unknown. METHODS: Over 26 months, 149 eligible Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With The Guidelines hospitals were randomized to receive either standard (n = 76 control) or targeted (n = 73 intervention) performance feedback reports for acute myocardial infarction patient care. Each report summarized performance on identified metrics (providing hospitals with detailed data on their 3 lowest-performing quality metrics, relative to their peers). Intervention sites received 5 targeted feedback reports. Overall composite performance was compared between cohorts at end of study and as a change from baseline. RESULTS: Intervention (n = 60) and control (n = 64) hospitals that completed the study had similar baseline performance (median score 83.7% vs 84.2%). Over 26 months of follow-up, the change in overall composite score across hospitals was neutral (median 0.1% [interquartile range {IQR} -2.4% to 3.3%]). There was no difference in observed improvement in either the intervention (median -0.2% [IQR-2.6% to 3.3%]) or control (median 0.1% [IQR -2.2% to 3.4%]) hospitals. CONCLUSIONS: We were unable to demonstrate that targeted performance feedback reports lead to more rapid care improvements than standard reports. Future directions should explore the relationship between hospital self-selection of targeted metrics and the identification and promulgation of less common metrics--particularly those that reflect processes of care.
