Incidence and predictors of early and late hospital readmission after transurethral resection of the prostate: a population-based cohort study.

Abstract

To evaluate the incidence and predictors of hospital readmission and emergency department (ED) visits in patients with benign prostatic hyperplasia treated by transurethral resection of the prostate (TURP). We conducted a retrospective cohort study using a linked administrative dataset from Calgary, Canada. Participants were men who underwent their first TURP procedure between 2015 and 2017. We examined patient demographics, and type of surgery (elective or urgent). Comorbidities were scored using the Charlson comorbidity index (CCI). The primary outcomes were unplanned hospital readmissions and ED visits at 30, 60 and 90 days after TURP. The secondary aim was to identify potential predictors across these groups. We identified 3059 men, most of whom underwent elective TURP (83%). The mean (sd) patient age was 71.0 (10.0) years. A total of 224 patients (7.4%) were readmitted to the hospital within 30days, 290 (9.5%) within 60days, and 339 (11.1%) within 90days of discharge. The frequency of return visits within 30, 60 and 90 days of TURP were 21.4%, 26% and 28.6%, respectively. The most responsible diagnoses for ED visit within 90days were haematuria (15.4%) and retention of urine (12.8%). Multivariable analysis showed that age (odds ratio [OR] 1.61, P < 0.001), surgery type (OR 2.20, P < 0.001), and CCI score (OR 2.03, P < 0.001) were independently associated with odds of readmission and ED visits at all time points. Older age, poorer health and urgent surgery predicted return to ED or readmission after TURP; efforts should be made to improve selection, counselling and preoperative optimization based on these risks.
