Gynecologists' sex, clinical beliefs, and hysterectomy rates.

This study determined how gynecologists' sex, beliefs, appropriateness ratings, and practice characteristics influence hysterectomy rates in North Carolina. Gynecologists who performed hysterectomies at higher rates were further from training, practiced in areas with fewer gynecologists, and had more patients with abnormal bleeding or cancer. Male gynecologists performed 60% more hysterectomies than female gynecologists, but this may have been because they were further from their training. Appropriateness ratings were affected by gynecologists' attitudes toward surgery, recency of training, and practice case mix, and by patients' expressed desire to avoid surgery, but they did not predict hysterectomy rates. To decrease their chances of undergoing hysterectomy, patients should express their preferences and possibly seek the opinion of more recently trained gynecologists.
