[MSB-05] Early Discharge After Isolated Coronary Artery Bypass Graft Surgery Does Not Increase Risk of Rehospitalization.

Objective: This study aimed to investigate whether early discharge after coronary artery bypass grafting (CABG) is associated with increased rates of hospital readmission and emergency room (ER) presentation. Methods: This retrospective cohort study utilized data from the Koşuyolu Adult Cardiac Surgery Quality Improvement Program database. Consecutive adults who underwent isolated CABG at a single institution between May 2023 and December 2023 were assessed for eligibility. Patients were excluded if they had surgery other than isolated CABG, experienced in-hospital mortality, or had a prolonged length of stay (>14 days) during index hospitalization. The study population was divided into early discharge (≤5 days) and late discharge (>5 days) groups. The primary endpoint was all-cause hospital readmission within 30 days of discharge, while the secondary endpoint was ER presentation for any reason within 30 days of discharge. Results: The final cohort included 608 patients (228 early-discharge, 380 late-discharge). Median age was 61 years (interquartile range, 54-67). Groups were balanced in terms of demographics, risk profile, operative details, and outcomes. Thirty-day rehospitalization and ER presentation rates were lower in the early discharge group compared to the late discharge group; however, the differences were statistically insignificant (7.0% Conclusion: Early discharge after isolated CABG surgery was not associated with increased rates of hospital readmission or ER presentation within 30 days of discharge.
