This activity is intended for healthcare providers delivering care to women and their families.
After completing this activity, the participant should be better able to:
1. Recall the factors that decrease the probability of TOLAC success
2. Discuss the scenarios in which a TOLAC would be an option to a patient requesting a TOLAC
Estimated time to complete activity: 0.25 hours

For Pharmacists: Upon successfully completing the post-test with a score of 100% and the activity evaluation form, transcript information will be sent to the NABP CPE Monitor Service within 4 weeks.
In support of improving patient care, this activity has been planned and implemented by the Postgraduate Institute for Medicine and The ObG Project. Postgraduate Institute for Medicine is jointly accredited by the Accreditation Council for Continuing Medical Education (ACCME), the Accreditation Council for Pharmacy Education (ACPE), and the American Nurses Credentialing Center (ANCC), to provide continuing education for the healthcare team.
Postgraduate Institute for Medicine designates this enduring material for a maximum of 0.25 AMA PRA Category 1 Credit(s)™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.
The maximum number of hours awarded for this Continuing Nursing Education activity is 0.2 contact hours.
The November 2017 ACOG practice bulletin on the safety and outcomes of trial of labor after cesarean (TOLAC) and Vaginal birth after cesarean (VBAC) replaces the previous 2010 practice bulletin.
While there are risks to TOLAC, most are related to complications, such as hemorrhage, that may arise from cesarean section in the setting of an unsuccessful trial of labor. However, TOLAC is still offered to patients as an option due to the significant risks associated with multiple repeat cesarean deliveries. Risks of placenta accreta, cystotomy, bowel injury, ureteral injury, and ileus, the need for postoperative ventilation, intensive care unit admission, hysterectomy, and blood transfusion requiring 4 or more units, and the duration of operative time and hospital stay significantly increase with increasing number of cesarean deliveries. In the NICHD MFMU study (Obstetrics and Gynecology 2006), Placenta accreta was present in 0.24% (1st cesarean sections [CS]) 0.31% (2nd CS), 0.57% (3rd CS), 2.13% (4th CS), 2.33% (5th CS), 6.74% (6 or more CS). Hysterectomy was required in 0.65% (1st CS) 0.42% (2nd CS) (0.90% (3rd CS) 2.41% (4th CS) 3.49% (5th CS) and 8.99% (6 or more CS). In 723 women who had previa in this study, risk for placenta accreta was 3% (1st CS), 11% (2nd CS), 40% (3rd CS) 61% (4th CS), and 67% (5 or more CS).
Clinical Factors and Probability of Success
Note: The ACOG VBAC guidance acknowledges MFMU Network calculators to assess predicted chance of a successful VBAC ( links below in ‘Learn More – Primary Source’ ) and states the following
Although such a calculator may provide more specific information about the chance of VBAC, which can be used by health care providers and their patients to further the process of shared decision making, no prediction model for VBAC has been shown to result in improved patient outcomes.
Take a post-test and get CME credits
OBG Project CME requires a modern web browser (Internet Explorer 10+, Mozilla Firefox, Apple Safari, Google Chrome, Microsoft Edge). Certain educational activities may require additional software to view multimedia, presentation, or printable versions of their content. These activities will be marked as such and will provide links to the required software. That software may be: Adobe Flash, Apple QuickTime, Adobe Acrobat, Microsoft PowerPoint, Windows Media Player, or Real Networks Real One Player.
This educational activity may contain discussion of published and/or investigational uses of agents that are not indicated by the FDA. The planners of this activity do not recommend the use of any agent outside of the labeled indications.
The opinions expressed in the educational activity are those of the faculty and do not necessarily represent the views of the planners. Please refer to the official prescribing information for each product for discussion of approved indications, contraindications, and warnings.
Participants have an implied responsibility to use the newly acquired information to enhance patient outcomes and their own professional development. The information
presented in this activity is not meant to serve as a guideline for patient management. Any procedures, medications, or other courses of diagnosis or treatment discussed or suggested in this activity should not be used by clinicians without evaluation of their patient’s conditions and possible contraindications and/or dangers in use, review of any applicable manufacturer’s product information, and comparison with recommendations of other authorities.
