Why the study?
Limited information exists regarding current trends, hospital variation, and the safety of same-day discharge after elective PCI in Canada.
Does same-day discharge after elective PCI maintain safety outcomes compared to an overnight stay in outpatients?
Population
35 972 outpatients undergoing elective PCI at 17 centers in Ontario, Canada
Comparison
Same-day discharge vs non-same-day discharge (1 overnight stay)
Design
Population-based propensity-weighted cohort study
Follow-up
30 days
Key result
Same-day discharge after elective PCI showed no significant difference in 30-day death or hospitalization for acute coronary syndrome compared with an overnight stay (HR 0.84; 95% CI 0.65-1.08; P=0.17).

Same-day discharge after elective PCI is safe and does not increase the 30-day risk of death or ACS hospitalization compared to an overnight stay.
Madan et al. (2019) conducted a cohort in Elective percutaneous coronary intervention (n=35,972). Same-day discharge (SDD) vs. Non-SDD (1 overnight stay) was evaluated on 30-day all-cause death or hospitalization for acute coronary syndrome (HR 0.84, 95% CI 0.65-1.08, p=0.17). Same-day discharge after elective PCI showed no significant difference in 30-day death or hospitalization for acute coronary syndrome compared with an overnight stay (HR 0.84; 95% CI 0.65-1.08; P=0.17).
