Safety of abortion and tubal sterilization performed separately versus concurrently

Concurrent abortion and sterilization are preferred by many women to avoid a second hospitalization, operation, and, in some instances, general anesthesia. Several authors have shown concern, however, that the two procedures carry a higher risk of morbidity when performed concurrently versus separately. To determine whether the concurrent performance of sterilization and induced abortion is as safe as the two procedures performed separately, we selected women undergoing these procedures from two separate multicenter, prospective, national United States studies: the Joint Program for the Study of Abortion and the Collaborative Review of Sterilization. Using standard definitions of major morbidity, we calculated the crude rate of one or more major complications to be 0.9% for the abortion-only group, 1.7% for the group concurrent abortion and tubal sterilization. Thus our data suggest that performing concurrent abortion and sterilization is as safe as performing those procedures separately.
