OBJECTIVE: To provide a multi-institutional analysis of clinical factors predicting unplanned hospital readmission after major inpatient urologic surgery. MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program is a risk-adjusted data collection mechanism for analyzing clinical outcomes data including 30-day perioperative readmissions and complications. We identified 23,108 patients who underwent major inpatient urologic surgery from 2011 to 2012. Readmission rates were determined and stratified by procedure type. Multiple logistic regression was used to determine independent risk factors for 30-day unplanned hospital readmissions. RESULTS: Of a total of 23,108 patients undergoing urologic surgery, 1329 patients (5.8%) had unplanned readmissions. Upper tract reconstruction and urinary diversion without cystectomy (21/102) and with cystectomy (291/1662) had the highest rates of readmission of all procedures analyzed. Readmitted patients had a 64.2% (853/1329) and 64.4% (855/1329) rate of major and minor complications, respectively, compared with 6.7% (1459/21,779) and 15.9% (3462/21,779) for patients not readmitted (P? < .02). Organ space infection (odds ratio [OR] 15.23), pulmonary embolism (OR 12.14), deep venous thrombosis (OR 10.96), and return to the operating room (OR 8.46) were the most substantial predictors of readmission. Laparoscopic-robotic procedures had significantly lower readmission rates compared with open procedures for prostatectomy, partial nephrectomy, and nephrectomy (P? < .01). CONCLUSION: Readmission after inpatient urologic surgery occurs at a rate of 5.8%, with cystectomy and urinary diversion demonstrating the highest rates. Major and minor postoperative complications were the most substantial predictors of readmission. These results may guide risk reduction initiatives to prevent readmissions after major urologic surgery.
