Thyroidectomy is one of the most common operations performed in the U.S, often due to thyroid cancer, over-activity, or enlargement of the thyroid gland, which is located at the base of the throat and produces hormones that regulate metabolism. But most consumers would be surprised to learn that about half (51 percent) of surgeons who perform thyroidectomy do so just once a year, according to a study published in the Annals of Surgery.
“This is a very technical operation, and patients should feel empowered to ask their surgeons how many procedures they do each year, on average,” said Dr. Julie A. Sosa, MD, senior author and Duke endocrine surgeon. “Surgeons have an ethical responsibility to report their case numbers. While this is not a guarantee of a positive outcome, choosing a more experienced surgeon certainly can improve the odds that the patient will do well.”
Although total thyroidectomy is generally safe, it can cause life-altering complications that were seen in some study patients, such as bleeding, problems with the parathyroid glands, and damage to the laryngeal nerve that can lead to difficulty speaking, breathing and swallowing. Any complication can require more care, driving up patient costs and potentially compromising quality of life.
The study evaluated data from 16,954 patients who had thyroidectomies between 1998 and 2009 and were enrolled in a national database from the Health Care Utilization Project.
In analyzing the case volumes of 4,627 surgeons, researchers found an association between the number of procedures surgeons performed each year and rates of complications. Notably, patients of surgeons who performed fewer than 25 thyroidectomies a year were 1.5 times more likely to experience complications.
As the average number of cases increased, the risk of complications for patients steadily decreased. Risks leveled out for surgeons who performed an average of 25 or more operations a year.
