An Administrative Claims Measure Suitable for Profiling Hospital Performance Based on 30-Day All-Cause Readmission Rates Among Patients With Acute Myocardial Infarction

We present the development and validation of a model approved by the National Quality Forum and used by the Centers for Medicare median difference, 0.02 percentage points). CONCLUSIONS: This claims-based model of hospital risk-standardized readmission rates for patients with acute myocardial infarction produces estimates that are excellent surrogates for those produced from a medical record model.
