Abstract

Postdischarge outcomes after percutaneous coronary intervention (PCI) are important measurements of quality of care and complement in-hospital measurements. We sought to assess in-hospital and postdischarge PCI outcomes to (1) better understand the relation between acute and 30-day outcomes, (2) identify predictors of 30-day hospital readmission, and (3) determine the prognostic significance of 30-day hospital readmission. We analyzed in-hospital death and length of stay (LOS) and nonelective cardiac-related rehospitalization after discharge in 10,965 patients after PCI in the Dynamic Registry. From 1999 to 2006 in-hospital death rate and LOS decreased. Thirty-day cardiac readmission rate was 4.6%, with considerable variability over time and among hospitals. Risk of rehospitalization was greater in women and those with congestive heart failure, unstable angina, multiple lesions, and emergency PCI. Conversely, a lower risk of rehospitalization was associated with a larger number of treated lesions. Patients readmitted within 30 days had higher 1-year mortality than those free from hospital readmission. In conclusion, although in-hospital mortality and LOS after PCI have decreased over time, the observed 30-day cardiac readmission rate was highly variable and risk of readmission was more closely associated with underlying patient characteristics than procedural characteristics.
