Trends and Outcomes After Same-Day Discharge After Percutaneous Coronary Interventions

Despite the demonstrated safety of the same-day discharge (SDD) after percutaneous coronary intervention (PCI), uptake of this program has been relatively poor in the United States. We evaluated the temporal trends and variations in the utilization of SDD after PCI during the contemporary era. In addition, we evaluated the predictors of SDD (compared with next-day discharge) and the causes of readmission in these 2 patient cohorts.

Data were extracted from State Ambulatory Surgical Database and State Inpatient Database from Florida and New York ranging from 2009 to 2013. All adults undergoing PCI in an outpatient setting were included. Data were merged with the directory available from the American Hospital Association to obtain detailed information on hospital-related characteristics. Unplanned readmissions within 7 and 30 days constituted the coprimary outcomes. There was modest increase in the proportion of SDD after PCI from 2.5% in 2009 to 7.4% in 2013 (P-trend <0.001). SDD was more frequently used among male and younger patients with fewer comorbidities. There were considerable differences in the discharge practices among the different hospital types. Larger hospitals, teaching hospitals, and high PCI volume hospitals had higher utilization of SDD compared with their respective counterparts. SDD and next-day discharge cohorts had similar rates of unplanned readmissions, in-hospital mortality, and acute myocardial infarction during follow-up. Furthermore, uninsured patients had significantly lower odds of SDD along with higher incidence of unplanned readmission within 30 days after PCI compared with insured patients.

During 2009 to 2013, there has been a modest increase in SDD after PCI. Several demographic and clinical characteristics play critical role in determination of SDD after PCI. There were significant disparities in discharge practices between different sex, racial, and insurance-based strata.
