Background: Limited data exist regarding in-hospital use of resources, LOS, and cost of RC-associated admissions in teaching hospital (TH) versus nonteaching hospital (NTH) settings. The goal of this study was to address the above void in literature. Methods:We focused on 13,272 admissions for RC between 2008-2014 within the National Inpatient Sample. Patients with concurrent diagnosis of other bladder conditions (n=914) were excluded. ICD-9 diagnosis and procedure codes were used to study inpatient procedures performed during admission. Type of admissions, receipt of a procedure, type of procedures performed, LOS, and total inflation-adjusted cost were then compared between TH and NTH. Complex survey chi-squared test and analysis of variance procedures were used to account for the NIS sampling design. Results: Of the 12,358 assessable records, 49% were at THs. Patients were more commonly admitted to emergency department at NTH (85%) compared to TH (80%; p<0.001). Weekend admissions were more common at NTH (24%) compared to TH (21%) (p=0.004). Receipt of a procedure during admission was higher in TH (65%) compared to NTH (60%; p<0.001). Number of procedure codes recorded was higher in TH (>= 2 codes; 28.9% in TH vs 24.5% in NTH; p <0.001. More complex procedures like cystectomy were almost exclusively performed at TH (cystectomy 2.4% in TH vs 0.4% in NTH admissions; p <0.001), whereas there was no difference in procedures like blood transfusion (TH 34%; NTH 33%; p=0.3), suprapubic cystostomy (TH 1.3%; NTH 1.4%; p=0.8), and transurethral procedures (TH 14%; NTH 16%; p=0.06). Despite statistically significant difference in LOS between the two groups (Median days (IQR): TH 5 (3-9); NTH 5 (3-8); p<0.001) the difference was not clinically significant. Cost of admission was higher in TH (10,377$ TH; 8504$ NTH; p<0.001). Conclusions: In the United States, patients with RC are more frequently admitted to the emergency department in NTH. Patients admitted to TH receive a procedure more often, receive a higher number of procedures, and more complex procedures, compared to NTH. This explains higher cost of admission in TH. Further research is needed to study the readmission rates and outcomes of patients treated in both types of health systems to know the best practices that can reduce morbidity and readmissions.
