Abstract 107: The Impact of Out-of-Hospital Cardiac Arrest Patients on Hospital Quality Reporting of Percutaneous Coronary Intervention; Can Prediction Models Do Better?

Objectives: This study aimed to develop a mortality risk model for percutaneous coronary intervention (PCI) specific to the Out of Hospital Cardiac Arrest (OHCA) population and assess the influence of these patients on currently publicly reported PCI metrics in Washington state. Methods: Our study analyzed 331 out of hospital cardiac arrest patients who underwent PCI in Washington state over a 1-year period. Data was obtained over a 2-year period from the Clinical Outcomes Assessment Program (COAP), a PCI public reporting program for Washington hospitals and Cardiac Arrest Registry to Enhance Survival (CARES), a disease-based OHCA registry. Stepwise multivariate logistic regression was used for model development and bootstrapping was performed. Model performance was analyzed using c statistic and the Hosmer Lemeshow goodness of fit tests. Results: The OHCA model contains seven predictors of mortality: age, GFR, cardiogenic shock, emergency-salvage priority, witnessed arrest, arrest after 911 arrival, and ...
