Abstract

Background: Post hoc analyses of clinical trials suggest that certain patients are eligible for early discharge after ST-segment elevation myocardial infarction. The extent to which ST-segment elevation myocardial infarction patients are discharged early after primary percutaneous coronary intervention (PPCI) in current practice is unknown. Methods: We examined 115,113 patients in the CathPCI Registry to assess temporal trends in length of stay (LOS) after PPCI. Baseline characteristics were compared between patients with LOS ≤2 and >2 days. Predictors of LOS >2 days were determined by logistic regression and adjusted for clustering among centers. Patterns of discharge within 2 days for low-risk patients with no inhospital complications were examined. Results: From January 2005 through March 2009, mean LOS (4.0 ± 3.0 to 3.6 ± 2.7 days) (P for trend <.001) and the proportion of patients discharged after 2 days decreased (72.0%-65.9%), while predicted inhospital mortality risk remained unchanged. Patients with LOS >2 days (n = 77,471; 67.3%) were older and more likely to have had an intra-aortic balloon pump, cardiogenic shock, transfusions, and post-PPCI complications. Of 958 hospitals, 437 (45.6%) discharged at least half of their low-risk patients with no inhospital complications within 2 days. Conclusions: While the predicted risk profile has remained stable, there has been a significant decrease in LOS after PPCI. Nevertheless, hospitals vary in discharging low-risk and uncomplicated patients early. Discharge within 2 days was associated with specific patient, procedure, and hospital factors. Further study is needed to determine the safety of early discharge among patients undergoing PPCI.
