Safety of Same-Day Discharge After Percutaneous Coronary Intervention in Selected Patients With Non-ST Elevation Acute Coronary Syndrome.

Objectives: We aimed to investigate the safety of same-day discharge (SDD) after percutaneous coronary intervention (PCI) for non-ST segment elevation acute coronary syndrome (NSTEACS), and to investigate the reduction in duration of hospitalization achievable by SDD.

Background: Previous studies have established the safety of SDD after elective PCI, while the safety of SDD after non-elective PCI for acute coronary syndrome has only been sparsely studied.

Methods: A single-center, observational, retrospective study of 923 consecutive procedures in patients with NSTEACS who had PCI was performed. The procedures were divided into 2 groups based on postprocedural management: SDD (n = 195) and non-SDD (n = 728).

Results: No differences were seen in the total number of adverse events at 1 month (1.5% SDD vs 1.4% non-SDD; P=.74), 3 months (2.5% SDD vs 2.3% non-SDD; P=.80), and 6 months (3.5% SDD vs 3.3% non-SDD; P=.84) after discharge, and there were no deaths in the SDD group. No difference was found in unplanned rehospitalizations within 6 months (20.5% SDD vs 25.3% non-SDD; P=.17), while unplanned revascularizations were more frequent in non-SDD patients (5.6% SDD vs 13.4% non-SDD; P<.01). Median duration of hospitalization was 1.3 days shorter for SDD patients than for non-elderly, uncomplicated non-SDD patients.

Conclusions: SDD after PCI in a selected group of NSTEACS patients was associated with low rates of adverse events, unplanned rehospitalizations, and revascularizations. SDD was associated with a shorter hospitalization duration.
