Abstract

OBJECTIVES:

To determine the incidence, risk factors and causes of hospital readmission in a large series of patients who underwent radical cystectomy (RC) and urinary diversion.

PATIENTS AND METHODS:

We retrospectively analysed the data of 1000 patients who underwent RC and urinary diversion between January 2004 and September 2009 in our tertiary referral centre. Patients stayed in hospital for 21 and 11 days for orthotopic and ileal conduit diversions, respectively. The primary outcome was the development of a complication requiring hospital readmission at ≤3 months (early) and >3 months (late). Causes of hospital readmissions were categorised according to frequency of readmissions. Predictors were determined using univariate and multivariate logistic regression models.

RESULTS:

In all, 895 patients were analysed excluding 105 patients because of perioperative mortality and loss to follow-up. Early and late readmissions occurred in 8.6% and 11% patients, respectively. The commonest causes of first readmission were upper urinary tract obstruction (UUO, 13%) and pyelonephritis (12.4%) followed by intestinal obstruction (11.9%) and metabolic acidosis (11.3%). The development of postoperative high-grade complications (odds ratio [OR] 1.955; 95% confidence interval [CI] 1.254-3.046; P = 0.003) and orthotopic bladder substitution (OR 1.585; 95% CI 1.095-2.295; P = 0.015) were independent predictors for overall hospital readmission after RC. Postoperative high-grade complications (OR 2.488; 95% CI 1.391-4.450; P = 0.002), orthotopic bladder substitution (OR 2.492; 95% CI 1.423-4.364; P = 0.001) and prolonged hospital stay (OR 1.964; 95% CI:1.166-3.308; P = 0.011) were independent predictors for early readmission while hypertension (OR 1.670; 95% CI 1.007-2.769; P = 0.047) was an independent predictor for late readmission.

CONCLUSION:

Hospital readmissions are a significant problem after RC. In the present study, UUO, pyelonephritis, metabolic acidosis and intestinal obstruction were the main causes of readmission. Orthotopic bladder substitution and development of postoperative high-grade complications were significant predictors for overall readmission.
