Early discharge and post-discharge outcomes in patients undergoing radical cystectomy for bladder cancer

To assess whether discharging patients early after radical cystectomy (RC) is associated with an increased risk of readmission and post-discharge complications.

The National Surgical Quality Improvement Program database was queried to identify patients who underwent an elective RC from 2012 to 2015. Patients were stratified into two groups: those with a length of hospital stay (LOS) of 4-5 days (early-discharge group) and those with an LOS of 6-9 days (routine-discharge group). We used multivariable logistic regression analyses to assess the impact of early discharge on 30-day readmission and post-discharge complication rates. Sensitivity analyses and subgroup analyses were performed to validate the robustness of our primary analyses.

A total of 3 311 patients were included. Unadjusted outcomes comparison showed no difference in readmission rate (21.6% vs 23.0%) or post-discharge complication rate (17.7% vs 19.6%) between the early-discharge and the routine-discharge group. Multivariable logistic regression also showed that early discharge was not associated with increased odds of readmission (odds ratio [OR] 1.00, 95% confidence interval [CI] 0.82-1.22; P = 1.000) or post-discharge complications (OR 0.95, 95% CI 0.77-1.17; P = 0.616). Two-step sensitivity analyses (excluding patients with LOS of 8-9 days, followed by patients with any pre-discharge adverse event) validated the robustness of our primary analyses. Subgroup analyses also yielded similar results in all subgroups except for the subgroup of patients aged ≥85 years.

Early discharge after RC was not associated with increased readmissions or post-discharge complications. Future prospective studies, with defined peri-operative care pathways, are needed to identify potential components that may enable hospitals to discharge patients early without compromising post-discharge outcomes.
