Background: Advancement in surgery has shifted numerous procedures to a same-day discharge (SDD) setting. In this study, we evaluated factors related to SDD after robotic transversus abdominis release (rTAR). Materials and Methods: A retrospective analysis of a prospectively maintained hernia databank was performed. Patients who underwent rTAR for incisional hernias were assigned to either the SDD group (length of stay [LOS] <1) or the inpatient group (LOS ≥1 day). Pre-, intra-, and postoperative variables were compared. Predictors of SDD were explored through a logistic regression, and a mediation analysis was performed to assess their effect on the LOS. Results: Out of the 167 patients included, 53 patients were discharged the same day. Age, American Society of Anesthesiologists score, history of coronary artery disease, and wound infection were significantly higher in the inpatient group. Overall, median LOS was 1 (0-2). Postoperative complications did not differ between SDD and inpatient groups except for Clavien-Dindo Grade-II (1 versus 14, respectively; P = .039). Thirty-day readmission rates were comparable (P = .229). A binary logistic regression to predict factors associated with SDD rTAR showed statistical significance in age, operative time, mesh area, and history of wound infection. Mediation analysis showed that mesh size indirectly affected the LOS through the operative time (a = 0.54; b = 0.46; P < .001). An age >46-year-old, an operative time beyond 217 minutes, and a mesh size >475 cm2 increased the probability of an inpatient stay (area-under-the-receiver operating characteristic curves: 0.69, 0.81, and 0.82, respectively). Conclusion: The pre- and intraoperative factors associated with SDD rTAR were age, history of wound infection, operative time, and mesh area. Further studies are needed to investigate the appropriateness of discharge decisions while balancing patients' benefits, resource utilization, and costs.
