Counseling women with a previous cesarean birth: toward a shared decision-making partnership.

Pregnant women who had a previous cesarean birth must choose whether to have a repeat cesarean or to attempt a vaginal birth. Many of these women are candidates for a trial of labor. Current practice guidelines recommend that women should be thoroughly counseled during prenatal care about the benefits and harms of both a trial of labor after cesarean (TOLAC) and an elective repeat cesarean delivery and be offered the opportunity to make an informed decision about mode of birth in collaboration with their provider. The purpose of this article is to improve the process of counseling, decision making, and informed consent by increasing health care providers' knowledge about the essential elements of shared decision making. Factors that affect the decisions to be made and concepts that are critical for effective counseling are explored, including clinical considerations, women's perspectives, decision-making models, health literacy and numeracy, communicating risk, and the use of decision aids. Issues related to birth sites for TOLAC are also discussed, including access, safety, refusal of surgery, and clinical management.
