Institutional trends and safety profile of same-day discharge for robot-assisted laparoscopic radical prostatectomy: A retrospective analysis

Purpose: To report the trends, predictors, and patient outcomes of same-day discharge (SDD) versus non-SDD for robot-assisted laparoscopic radical prostatectomy (RALP). Materials and Methods: We queried our centralized data warehouse to identify men with prostate cancer who underwent RALP between January 2020 and May 2022. Patient demographics and clinical characteristics were compared between SDD and non-SDD. Then, we examined the utilization of SDD in a univariable logistic regression. Then, we fitted a logistic regression model to identify the predictors of SDD. To examine the safety profile of SDD, an inverse probability of treatment weighting (IPTW) adjusted logistic regression was fitted to examine the effect of SDD on 30-day postoperative complications and readmissions. Results: Overall, 1,153 patients underwent RALP, of which 224 (19.4%) were SDD. The proportion of SDD increased from 4.4% in the fourth quarter of 2020 to 45% in the second quarter of 2022 (p < 0.01). The predictors of SDD were the facility where the surgery was performed (OR: 1.57; 95%CI [1.08−2.28]; p = 0.02) and whether a high-volume surgeon performed it (OR: 1.96; 95%CI [1.09−3.54]; p = 0.03). After IPTW, SDD compared to non-SDD was not associated with a difference in complications (OR: 1.07; 95%CI [0.38−2.95]; p = 0.90) or readmissions (OR: 1.22; 95%CI [0.40−3.74]; p = 0.72). Conclusion: In our health system, the use of SDD is safe and currently composes of half of our RALP volume. With the advent of the hospital-at-home services, we anticipate that almost all our RALP cases will be SDD.
