Impact of same-day discharge (SDD) on cost of hospitalization following elective percutaneous coronary interventions (PCI) is unclear.
Nationwide Inpatient Sample data files from 2003 to 2014 were used to extract adult patients (age > 18 years) who underwent elective PCI. Patients who developed major complications (acute stroke, gastrointestinal bleeding, acute kidney injury, cardiac arrest, cardiogenic shock, vascular complications, and in-hospital mortality) after PCI were excluded to identify those with uncomplicated hospital stay. Patients who were discharged on the same day after the procedure were identified if their length of hospitalization was zero days. Propensity score matched analysis was performed to adjust for baseline characteristics between SDD and non-SDD groups. Linear regression model was used to assess the effect of SDD on cost of hospitalization.
Of 370,161 uncomplicated elective PCI procedures, 3,475 patients (0.9%) were discharged on the same day after the procedure. After adjusting for the differences in baseline characteristics, 5,222 uncomplicated PCIs were identified, of which 2,611 patients were discharged on the same day following the procedure and 2,611 patients were not discharged on the same day. SDD was associated with a significant reduction in cost of hospitalization (cost difference ($) = – 5,678; 95% CI = – 2,681 to – 5,501; P=0.0005).
SDD is associated with a significant reduction in cost of hospitalization following uncomplicated elective PCI.
