Introduction: We have witnessed the slow uptake of many contemporary techniques in the surgical management of renal tumours. We sought to evaluate surgeon-level characteristics associated with the uptake of laparoscopy, partial nephrectomy (PN) and adrenal-sparing approaches in surgically managing these tumours.
Methods: Using the Ontario Cancer Registry, we identified surgeons treating renal cell carcinoma (RCC) in the province of Ontario, Canada between 2002 and 2004. We then classified individuals within this cohort as either high or low utilizers of laparoscopy, PN or adrenal-sparing approaches. Further variables analyzed included academic status, surgeon graduation year and surgical volume status. We then used univariable and multivariable logistic regression models to assess predictors of uptake.
Results: We evaluated a total of 108 surgeons for their uptake of both laparoscopy and adrenal-sparing approaches and 94 surgeonsfor their uptake of PN. We identified 32 surgeons (30%) as high users of laparoscopy. Predictors of uptake of laparoscopy included graduation year after 1990 (odds ratio [OR] 4.81, confidence interval [CI] 1.57-14.8) and high-surgeon volume (OR 4.33, CI1.60-10.4). We identified 41 surgeons (44%) as high users of PN. The only predictor of uptake of PN was academic status (OR 5.83,CI 1.96-17.3). We identified 69 surgeons (65%) as high users of adrenal-sparing approaches, but did not identify any significant predictors for uptake in this group.
Discussion: We identify unique factors contributing to the uptake of distinct surgical techniques in the management of RCC. This information sheds lights on the underlying mechanisms and helps us understand how to further encourage the dissemination of these practices.
