Insights
Same-day discharge (SDD) is feasible for over 85% of patients undergoing left atrial appendage occlusion (LAAO). Rehospitalization rates within 30 days were similar for patients discharged same-day versus overnight.
Area of Science:
- Cardiology
- Medical Procedures
Background:
- Evolving data exists on same-day discharge (SDD) safety post-left atrial appendage occlusion (LAAO).
- Assessing SDD feasibility and outcomes is crucial for patient management.
Purpose of the Study:
- To evaluate the feasibility of same-day discharge (SDD) after left atrial appendage occlusion (LAAO).
- To compare 30-day rehospitalization rates between SDD and overnight admission groups post-LAAO.
Main Methods:
- Single-centre retrospective study.
- Comparison of outcomes for patients discharged same-day versus those admitted overnight after LAAO.
Main Results:
- Over 85% of patients undergoing LAAO were safely discharged on the same day.
- The 30-day rehospitalization rate was comparable between the same-day discharge and overnight admission groups.
- Approximately 10% of all patients were rehospitalized within 30 days post-LAAO.
Conclusions:
- Same-day discharge is a safe and feasible option for a majority of patients undergoing LAAO.
- LAAO patient outcomes, specifically 30-day rehospitalization, are not significantly different between same-day discharge and overnight admission strategies.
Abstract:
Information is evolving on the safety of same-day discharge (SDD) after left atrial appendage occlusion (LAAO) procedures. This single-centre retrospective study evaluated the feasibility of SDD and reported on the 30-day rehospitalization rate in patients discharged same-day compared with those admitted overnight after LAAO. Key findings of this study included more than 85% of patients with LAAO were safely discharged same-day; the rate of postdischarge rehospitalization was similar in SDD patients and those admitted overnight; and approximately 1 in 10 patients who had LAAO procedures were rehospitalized within 30 days postprocedure.
