Background: To compare the rate of hospital based outcomes in patients with urologic malignancies who underwent surgery as part of treatment in academic and community hospitals. Methods: We reviewed the Vizient Clinical Database from September 2014 to December 2017. Vizient is a member-driven health services organization that includes ~99% of academic hospitals (AH) and more than 40 community hospitals (CH). This is a comparative database comprised of administrative billing. Data include patient demographics, readmission rates, costs, LOS, case mix index (CMI) and mortality. Patients aged ≥ 18 were included and ICD-9 and ICD-10 codes were used to identify patients with urologic malignancies who underwent surgical treatment. Chi square and student t-tests were used to compare categorical and continuous variables, respectively. Results: We identified a total of 37,628 cases. There were 33,290 (88%) procedures performed in AH and 4,330 (12%) in CH. These included radical prostatectomy (RP) 18,540, radical nephrectomy (rNx) 8,059, partial nephrectomy (pNx) (5,287), radical cystectomy (4,421), radical nephroureterectomy (rNu) (1,006), and partial cystectomy (321). There were no significant differences in 30-day readmission rates or mortality for any procedure between AH and CH. LOS was significantly lower (P<0.01) for radical cystectomy (8.83 vs 11.43 days) and RP (1.63 days vs 1.77 days) in AH, and lower in CH for rNx (4.93 vs 4.51, P: 0.03). AH had a significantly lower amount of partial cystectomies performed when compared to community centers (6.2% vs 16.2% P<0.001), and a similar number of partial nephrectomies performed (39.8% vs 38.0%, P=0.2). The mean direct cost for index admission was significantly higher in AH for rNx, pNx, rNu, and RP. Case complexity using the CMI was similar between CH and AH. Conclusions: The Vizient clinical database provides a novel resource for observational data at US hospitals. Despite academic and community hospitals having similar case complexity, direct costs were lower in community hospitals without an associated increase in readmission rates or deaths. The only clinically significant difference in length of stay was shorter stays for cystectomy in academic centers.
