Uptake of Same-Day Discharge for Patients Undergoing Robot-Assisted Radical Prostatectomy in the Michigan Urological Surgery Improvement Collaborative.

ABSTRACT

INTRODUCTION: Postoperative length of stay (LOS) after robot-assisted radical prostatectomy (RARP) is a potentially modifiable aspect of prostate cancer care. Our objective was to evaluate the use of same-day discharge (SDD) RARP and compare pre- and perioperative characteristics of these men with those who underwent hospitalization postoperatively. METHODS: Perioperative outcomes for patients undergoing RARP were evaluated from the Michigan Urological Surgery Improvement Collaborative (MUSIC) registry. Men were classified by hospital LOS SDD, 1 day, and 2 days. Practice and surgeon-level variation of SDD and the change in SDD use over time were assessed. The primary outcome was 30-day readmission after RARP. RESULTS: We identified 10,249 men undergoing RARP in MUSIC from 2018 to 2022. Most patients had 1-day LOS (79.6%), with 2.8% undergoing SDD. The proportion of patients undergoing RARPs with SDD rose from 0.6% in 2018 to 1.2% in 2019 and 4.4% for 2020 to 2022. At least one SDD was performed in 12 of 28 MUSIC practices (42.9%) and by 52 of 138 urologists (37.7%). In multivariable analysis, odds of 30-day readmission were not significantly different between patients .undergoing SDD and LOS 1 day (OR 1.72, 95% CI 0.92-3.22, P = .090). Limitations include retrospective, registry-based observational study with nonuniform utilization of SDD. CONCLUSIONS: Although more patients have undergone SDD after RARP beginning in 2018, rates across Michigan have remained < 5% annually. Importantly, patients undergoing SDD RARP did not experience significantly more readmissions compared to hospitalized patients. SDD appears safe and feasible for select patients who are motivated by this approach.
