Newly trained pediatric urologists encounter varied case complexity and diversity, with many performing predominantly minor procedures. Male surgeons generally perform more operations, highlighting the need for continued education and mentorship post-fellowship.
Area of Science:
- Urology
- Surgical Education
- Pediatric Surgery
Background:
- Pediatric urology fellowships aim to prepare surgeons for early career cases.
- Concerns exist regarding the actual complexity and diversity of cases new pediatric urologists perform.
- Understanding practice patterns is crucial for surgical training and workforce planning.
Purpose of the Study:
- To determine the frequency of procedures performed by newly trained pediatric urologists.
- To identify factors influencing case complexity and diversity.
- To assess differences in surgical case volume and complexity between male and female surgeons.
Main Methods:
- Review of case logs from pediatric urologists applying for certification between 2007 and 2013.
- Analysis of 51 index cases per urologist, assessing procedure complexity and diversity (CPT codes).
- Comparison of case volumes and complexity based on surgeon demographics (sex) and practice volume quartiles.
Main Results:
- Surgeons in the highest case volume quartile performed significantly more cases across all complexity levels compared to the lowest quartile.
- Common procedures included circumcisions, orchiopexies, and inguinal hernia repairs; rare procedures included open nephroureterectomies and complete male epispadias repair.
- Male surgeons performed more cases overall, particularly those of minimal and significant complexity, compared to female surgeons.
Conclusions:
- Significant variability exists in case diversity and complexity among newly trained pediatric urologists.
- The majority of new pediatric urologists perform a high volume of minor procedures.
- Disparities in operative experience, particularly between male and female surgeons, underscore the importance of ongoing education and mentorship.
