Changing the model of care during the COVID-19 pandemic: Same-day discharge of patients undergoing elective invasive cardiac procedures in Hong Kong.

BACKGROUND: Despite an evidence-based protocol to facilitate same-day discharge (SDD) of patients undergoing elective intracoronary procedures, overnight hospitalization remains a routine practice. OBJECTIVES: This study aimed to determine the frequency of SDD after intracoronary procedures among patients treated before and during the COVID-19 pandemic, and identify factors predictive of a decision for SDD. METHODS: This retrospective cohort study (N = 680) was based on registry data of a cardiac ambulatory center. RESULTS: The frequency of SDD was significantly higher in 2020 relative to 2019 (p < 0.001). No complication were identified during the next-day follow-up among SDD cohort. Compared to those who stayed overnight, SDD patients had a lower 30-day readmission rate (p < 0.001), but not 30-day mortality (p = 1.000). Radial access, some procedural-related and comorbidities of patients significantly predicted SDD. CONCLUSIONS: SDD is safe and feasible when a dedicated protocol has been implemented. The findings support the routine use of this practice.
