The impact of robotic surgery on the surgical management of prostate cancer in the USA BJU INTERNATIONAL Chang, S. L., Kibel, A. S., Brooks, J. D., Chung, B. I. 2015; 115 (6): 929-936

Abstract

To describe the surgeon characteristics associated with RARP adoption and determine the possible impact of this adoption on practice patterns and cost.A retrospective cohort study with a weighted sample size of 489,369 men who underwent non-RARP (i.e., open or laparoscopic radical prostatectomy [RP]) or RARP in the United States from 2003 to 2010 was performed. We evaluated predictors for RARP adoption, defined as performing >50% of annual RP with the robotic approach. Additionally, we identified the resulting changes in prostate cancer surgery practice patterns and expenditures.From 2003 to 2010, RARP adoption increased from 0.7% to 42% of surgeons performing RP. High-volume surgeons, defined as performing >24 RP annually, had statically significantly higher odds of adopting RARP throughout the study period. From 2005 to 2007, adoption was more common among surgeons at teaching (OR: 2.4; 95% CI: 1.7-3.4), intermediate- (200-399 beds; OR: 5.96; 95% CI: 1.3-26.5) and large-sized hospitals (=400 beds; OR: 6.1; 95% CI: 1.4-25.8); after 2007, adoption was more common among surgeons at urban hospitals (OR: 3.3; 95% CI: 1.7 to 6.4). RARP adoption was generally associated with increased RP volume, greatest for high-volume surgeons and least for low-volume surgeons (<5 RP annually). The annual number of surgeons performing RP decreased from approximately 10,000 to 8,200, with the proportion of cases performed by high-volume surgeons increasing from 10% to 45%. RARP was more costly, disproportionally contributing to the 40% increase in annual prostate cancer surgery expenditures. RARP costs generally decreased plateauing at over $10,000 while non-RARP costs increased to nearly $9,000 by the end of the study.There was widespread RARP adoption in the United States between 2003 and 2010, particularly among high-volume surgeons. The diffusion of RARP was associated with a centralization of care and an increased economic burden for prostate cancer surgery.
