C-68 | Readmission Outcomes in those with Same Day Discharge After Percutaneous Coronary Intervention for Non-ST Elevation Myocardial Infarction

Same day discharge (SDD) following elective percutaneous coronary intervention (PCI) is safe, increases patient satisfaction, and may provide an economic advantage to hospitals. Outcomes associated with SDD after PCI for NSTEMI are not well characterized. Patients with a primary diagnosis of NSTEMI and PCI were identified using the National Readmissions Database (NRD) from 2014 to 2020. Patients with death within 2 days of admission or a secondary diagnosis of cardiogenic shock or cardiac arrest were excluded. Patients with SDD (LOS of 0 days) were compared with patients without SDD. Outcomes were 90-day all-cause, cardiovascular and bleeding readmissions. Cox proportional hazards modeling with propensity weighting was used to determine the association between SDD and outcomes using the no SDD group as the reference. A total of 592,177 patients were included, of whom 3,891 (0.7%) had SDD. After PSW, all variables were balanced between groups. There was no significant association between SDD and 90-day all-cause, CV or bleeding readmissions (Figure 1). These findings suggest that SDD following NSTEMI may be feasible and safe in appropriately selected, low-risk patients without increased 90-day all-cause, CV, and bleeding readmissions. Further investigation is necessary to better characterize those most appropriate for SDD following NSTEMI.
