Urologic oncology case volume among early career urologists: An analysis of certification data from the American board of urology between 2003 and 2019.

Abstract

Introduction: The incidence of urologic cancer is expected to increase as the U.S. population ages, but the size of the urologic workforce is not expected to increase at a commensurate rate. To understand this growing imbalance, we explored the extent to which early career urologists performed oncology cases, particularly open surgical cases, between 2003 and 2019.

Materials and methods: We examined case logs submitted by early career urologists applying for their oral American Board of Urology Certifying Examination (Part 2) between 2003 and 2019. We included case logs spanning at least 120 days between the first and last record. We used CPT® codes to identify urologists who performed an open radical cystectomy, nephrectomy, or prostatectomy, as well as those who performed a minimally invasive (MIS) radical nephrectomy or prostatectomy. We calculated the annual percentage of urologists who performed each procedure. Multivariable logistic regression analysis analyzed the association between performing each procedure and specialization or fellowship training in oncology, adjusting for gender, practice type, and year of case log submission.

Results: We identified 4,166 unique urologists submitting case logs between 2003 and 2019. Their average age was 34.9 years, 81.3% were male, 14.2% specialized in oncology, and 8.2% reported oncology fellowship training. From 2003 to 2019, the percentage of urologists who performed open oncologic procedures decreased, while the percentage who performed MIS oncologic procedures increased. Fellowship training in oncology significantly increased the odds of performing the following procedures: open radical cystectomy (72.5% with fellowship training vs. 30.0% without fellowship training, OR 2.51, 95% CI 0.63-0.92, P < 0.001), open radical nephrectomy (74.3% with fellowship training vs 42.4% without fellowship training, OR 2.02, 95% CI 1.48-2.78, P < 0.001), open radical prostatectomy (42.1% with fellowship training vs. 26.9% without fellowship training, OR 1.86, 95% CI 1.34-2.58, P < 0.001) and MIS radical prostatectomy (80.4% with fellowship training vs. 45.0% without fellowship training, OR 1.69, 95% CI 1.16-2.48, P = 0.006). When comparing those with solely oncology specialization to those with both oncology specialization and fellowship training, we found that those with oncology fellowship training had over 2 times higher odds of performing open radical cystectomy (OR 2.58, CI 1.78-3.74, P < 0.001), open radical nephrectomy (OR 2.06, CI 1.42-2.99, P < 0.001) and open radical prostatectomy (OR 2.12, CI 1.44-3.12, P < 0.001). Female urologists had significantly lower odds of performing each oncologic procedure.

Conclusions: In this analysis of early career urologist case logs, the proportion of urologists performing a radical cystectomy, radical nephrectomy, and open prostatectomy declined between 2003 and 2019. Oncology specialization or fellowship training, however, significantly increased the odds of performing the procedures. Specifically, oncology fellowship alone was associated with over 2 times the odds of performing major open oncologic procedures. These findings reflect ongoing specialization among early career urologists, such that an oncology fellowship or practice focus has likely become necessary for access to open urologic procedures and to become a high-volume urologic oncology surgeon.
