abstract

  • OBJECTIVES: To test rates over time of robotic partial and radical nephrectomy (RPN and RRN) at teaching vs nonteaching institutions and to examine associated complication rates and length of stay. MATERIALS AND METHODS: Within the National Inpatient Sample (2008-2013), after stratification according to institutional teaching status, we examined the rates of robotic, open, and laparoscopic PN and RN. Subsequently, we tested complication rates and length of stay associated with RPN or RRN according to institutional teaching status. We relied on estimated annual percentage change (EAPC) with the least squares linear regression to test temporal trends and on multivariable logistic regression (MLR) and Poisson regression models to test complication rates and length of stay. RESULTS: Overall, 4070 and 1683 RPN and RRN were identified. In MLR, RPN rates were lower at teaching vs nonteaching institutions (odds ratio [OR]: 0.79, p < 0.001). RPN increased at similar rates over time at teaching and nonteaching institutions (EAPC: +32.1% and +30.1%, all p < 0.05). In MLR, RRN rates were similar at teaching and nonteaching institutions (p: 0.4). RRN rate increase over time was of similar magnitude at teaching vs nonteaching institutions (EAPC: +35.5% and +43.0%, all p < 0.05). RPN at teaching institutions yielded higher genitourinary complication rates (OR: 1.46, p: 0.01). RRN at teaching institutions resulted in lower respiratory complications (OR: 0.66, p: 0.04) and shorter length of stay (rate ratio [RR]: 0.93, p: 0.01), but higher intraoperative complication rates (OR: 3.39, p: 0.04). CONCLUSION: Despite statistically significant differences in rates of RPN use, according to the institutional teaching status and despite statistically significant difference in selected complications, no meaningful differences distinguish teaching vs nonteaching institution when RPN and RRN are considered.
