Development of 2 Registry-Based Risk Models Suitable for Characterizing Hospital Performance on 30-Day All-Cause Mortality Rates Among Patients Undergoing Percutaneous Coronary Intervention.

The article presents a research study that developed models of percutaneous coronary interventions (PCI) mortality using merged clinical data from the CathPCI Registry and administrative claims to produce hospital-specific risk standardized 30-day PCI mortality rates. Methods are presented involving data sources, outcome and candidate and final variables. Results of the analysis are discussed indicating the registry-based models produce estimates of hospital risk-standardized mortality rates.
