Outcomes for urologic oncology procedures: are there differences between academic and community hospitals?

OBJECTIVE: To compare the rate of hospital-based outcomes including costs, 30-day readmission, mortality, and length of stay in patients who underwent major urologic oncologic procedures in academic and community hospitals. METHODS: We retrospectively reviewed the Vizient Database (Irving, Texas) from September 2014 to December 2017. Vizient includes ~ 97% of academic hospitals (AH) and more than 60 community hospitals (CH). Patients aged ≥ 18 with urologic malignancies who underwent surgical treatment were included. 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 4330 (12%) in CH. These included prostatectomy (18,540), radical nephrectomy (rNx) 8059, partial nephrectomy (pNx) (5287), radical cystectomy (4421), radical nephroureterectomy (rNu) (1006), and partial cystectomy (321). There were no significant differences in 30-day readmission rates or mortality for any procedure between academic and community hospitals (Table 1), p > 0.05 for all. Length of stay was significantly lower for radical cystectomy and prostatectomy in AH (p < 0.01 for both) and lower for rNx in CH (p = 0.03). The mean direct cost for index admission was significantly higher in AH for rNx, pNx, rNu, and prostatectomy. Case mix index was similar between the community and academic hospitals. CONCLUSION: 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. Length of stay was shorter for cystectomy in academic centers.
