Importance Studies demonstrate that use of prostate-specific antigen screening decreased significantly following the US Preventive Services Task Force (USPSTF) recommendation against prostate-specific antigen screening in 2012. Objective To determine downstream effects on practice patterns in prostate cancer diagnosis and treatment following the 2012 USPSTF recommendation. Design, Setting, and Participants Procedural volumes of certifying and recertifying urologists from 2009 through 2016 were evaluated for variation in prostate biopsy and radical prostatectomy (RP) volume. Trends were confirmed using the New York Statewide Planning and Research Cooperative System and Nationwide Inpatient Sample. The study included a representative sample of urologists across practice settings and nationally representative sample of all RP discharges. We obtained operative case logs from the American Board of Urology and identified urologists performing at least 1 prostate biopsy (n = 5173) or RP (n = 3748), respectively. Exposures The 2012 USPSTF recommendation against routine population-wide prostate-specific antigen screening. Main Outcomes and Measures Change in median biopsy and RP volume per urologist and national procedural volume. Results Following the USPSTF recommendation, median biopsy volume per urologist decreased from 29 to 21 (interquartile range [IQR}, 12-34; P < .001). After adjusting for physician and practice characteristics, biopsy volume decreased by 28.7% following 2012 (parameter estimate, −0.25; SE, 0.03; P < .001). Similarly, following the USPSTF recommendation, median RP volume per urologist decreased from 7 (IQR, 3-15) to 6 (IQR, 2-12) (P < .001), and in adjusted analyses, RP volume decreased 16.2% (parameter estimate, −0.15; SE, 0.05; P = .003). Conclusions and Relevance Following the 2012 USPSTF recommendation, prostate biopsy and RP volumes decreased significantly. A panoramic vantage point is needed to evaluate the long-term consequences of the 2012 USPSTF recommendation.
