Barriers to labor after cesarean: A survey of United States midwives.

Introduction: Despite calls for increased vaginal birth after cesarean (VBAC), <14% of candidates have VBAC. Requirements for documentation of scar type, and prohibitions on induction or augmentation of labor are not supported by evidence but may be widespread. The purpose of this study was to document midwives' perceptions of barriers to labor after cesarean (LAC) and their effects on midwives' ability to accommodate patient desires for LAC.

Methods: Midwives certified by the American Midwifery Certification Board (AMCB) were surveyed in 2019. Multiple option and open-ended text responses were analyzed using quantitative statistics and thematic content analysis. Select barriers to LAC, ability to accommodate LAC, and supportiveness of collaborators among midwives offering LAC were explored.

Results: Responses from 1398 midwives were analyzed. Eighty-four percent felt able to accommodate LAC "most of the time," and 39% reported one or more barriers to LAC. Barriers decreased ability to accommodate LAC by as much as 80%. Analysis of text responses revealed specific themes.

Conclusions: Thirty-nine percent of midwives reported their practice was limited by one or more barriers that were inconsistent with professional guidelines. Imposition of barriers was driven primarily by collaborating physicians, and superceded supportive practices of midwives, nurses, and system administrators. Affected midwives were significantly less able to accommodate patient requests for LAC than those not affected. Midwives also reported pride in providing VBAC care, restrictions specific to midwifery scope of practice, and variation in physician support for LAC within practices affecting their ability to provide care.
