Predictors of failed same-day discharge in patients undergoing robot-assisted radical prostatectomy in a Canadian universal healthcare system.

Abstract

Introduction: Same-day discharge (SDD) after robot-assisted radical prostatectomy (RARP) has been shown to be feasible and safe. In order to improve uptake of this ambulatory model in Canada, we aimed to update our experience of SDD after RARP and identify reasons for SDD pathway non-initiation and failure in a universal healthcare system.

Methods: A review of our prospectively collected database of patients undergoing RARP at a Canadian tertiary academic center from May 2021 to May 2023 was conducted. Binary logistic regression analysis determined predictors SDD pathway non-initiation and failure.

Results: We identified 387 patients, of which 198 were initiated on the SDD pathway. Of those initiated, 104 (51.7 %) were successfully discharged home on the same day. Patients who travelled distances greater than 100 km, or who had non-CPAP compliant obstructive sleep apnea were significantly less likely to be initiated on the SDD pathway (both p<0.05). Patients that were scheduled to be the second case or later, had an estimated blood loss ≥300 mL, or had a postoperative abdominal drain, were predictive of failing SDD after initiation (all p<0.05). There were similar rates of readmissions, unscheduled office visits, and emergency department presentations, when compared to the traditional in-patient model (all p>0.05).

Conclusions: SDD after RARP in a Canadian healthcare system remains feasible and safe for selected patients. Predictors of failed SDD identified in this study inform the development of future ambulatory protocols and highlight areas of need in infrastructure to increase uptake of these outpatient pathways.
