Introduction: Most patients undergoing a left atrial appendage occlusion (LAAO) procedure are admitted for overnight observation. A same-day discharge strategy offers the opportunity to improve resource utilization without compromising patient safety. We compared the patient safety outcomes and post-discharge complications between same-day discharge versus hospital admission (HA) (>1 day) in patients undergoing LAAO procedure.
Methods: A systematic search of MEDLINE and Embase was conducted. Outcomes of interest included peri-procedural complications, re-admissions, discharge complications including major bleeding and vascular complications, ischemic stroke, all-cause mortality, and peri-device leak >5 mm. Mantel-Haenszel risk ratios (RRs) with 95% CIs were calculated.
Results: A total of seven observational studies met the inclusion criteria. There was no statistically significant difference between same-day discharge versus HA regarding readmission (RR: 0.61; 95% confidence interval [CI]: [0.29-1.31]; p = .21), ischemic stroke after discharge (RR: 1.16; 95% CI: [0.49-2.73]), peri-device leak >5 mm (RR: 1.27; 95% CI: [0.42-3.85], and all-cause mortality (RR: 0.60; 95% CI: [0.36-1.02]). The same-day discharge study group had significantly lower major bleeding or vascular complications (RR: 0.71; 95% CI: [0.54-0.94]).
Conclusions: This meta-analysis of seven observational studies showed no significant difference in patient safety outcomes and post-discharge complications between same-day discharge versus HA. These findings provide a solid basis to perform a randomized control trial to eliminate any potential confounders.
