Purpose: Historically, robotic-assisted radical prostatectomy is accompanied by an inpatient hospital admission. The COVID-19 pandemic necessitated a transition to same-day discharge robotic-assisted radical prostatectomy in some centers to free up critically needed inpatient beds. This study aims to compare complications, total health care costs, and patient satisfaction for same-day discharge vs inpatient robotic-assisted radical prostatectomy.
Materials and methods: We compared 392 consecutive robotic-assisted radical prostatectomies performed as same-day discharge (n = 206) vs inpatient (n = 186) from February 2020 to November 2022 at 2 academic medical centers. We utilized propensity score analysis to assess the impact of same-day discharge vs inpatient robotic-assisted radical prostatectomy on 30-day complications (primary outcome). Time-driven activity-based costing analysis was applied to compare total costs of robotic-assisted radical prostatectomy care, and we administered a validated Patient Satisfaction Outcome Questionnaire to compare satisfaction scores.
Results: Inpatient robotic-assisted radical prostatectomy patients were more likely to be older, self-reported Black race or Hispanic ethnicity, and have higher American Society of Anesthesiologists classification. Complication rates were nonsignificantly lower for same-day discharge vs inpatient robotic-assisted radical prostatectomy (OR 0.87, 95% CI 0.35 to 2.21; P = .8). Same-day discharge vs inpatient robotic-assisted radical prostatectomy demonstrated a $2106 (19%) overall cost reduction. Median satisfaction survey scores were similar, and a clinically significant difference can be excluded.
Conclusions: Same-day discharge robotic-assisted radical prostatectomy is cost-effective and should be the preferred approach in appropriately selected patients.
