Colorectal procedures: what proportion is performed by American board of colon and rectal surgery-certified surgeons?
OBJECTIVE
The surgical workforce within the United States is moving rapidly toward increasing subspecialization. We hypothesized that over time an increasing proportion of colorectal procedures is performed by subspecialty-trained colorectal surgeons.


METHODS
We used data from the Surveillance, Epidemiology, and End Results-Medicare program to examine the treatment of patients who underwent a colorectal surgical procedure between 1992 and 2002. We established whether the surgeon responsible for the patient's initial care was a board-certified colorectal surgeon based on a linkage with 2 overlapping data sources: 1) historical data from the American Board of Colon and Rectal Surgery and 2) the American Medical Association Physician Masterfile.


RESULTS
We examined a total of 104,636 procedures; overall, 30.6% of anorectal procedures, 22.0% of proctectomies, 14.0% of ostomy-related procedures, and 11.5% of colectomies were performed by board-certified colorectal surgeons. Procedures in regions with lower population density or during urgent/emergent hospitalizations were more likely to be performed by a noncolorectal surgeon. Operations for cancer and those performed on an elective basis were more likely to be performed by a board-certified colorectal surgeon. Over time, the proportion of each of these types of cases performed by a colorectal surgeon increased. This increase was fastest for anorectal procedures.


CONCLUSIONS
During the 11-year period of our study, there was a significant increase in the proportion of colorectal surgical procedures performed by board-certified colorectal surgeons.
