Effect of a patient-centered decision app on TOLAC: An RCT

Project: Research project

Project Details

Description

Cesarean delivery (CD) accounts for one-third of all births in the US, representing an increase of approximately 50% in the last decade. Elective repeat CDs (ERCD) are a significant contributor to the rising cesarean rate, resulting from the combination of an increasing rate of primary CD and a decreasing rate of vaginal birth after cesarean (VBAC). A primary driver of the decreased frequency of VBAC is the decline in frequency with which eligible women elect a trial of labor after cesarean (TOLAC). The reasons for this decline are unclear; in particular, little is known about the extent to which patient preferences have contributed to this decrease. In addition, tools to help patients and providers engage in patient-preference driven, shared decision making regarding approach to delivery after cesarean are lacking.
We propose to 1) identify patient preference drivers of delivery approach (TOLAC or ERCD) and mode (VBAC or CD) among 240 English- or Spanish-speaking TOLAC-eligible women; 2) use this data to create an innovative, personalized decision support mHealth app (Prior CD Decision App) that integrates values clarification exercises with a validated VBAC prediction tool; and 3) conduct a randomized trial of the Prior CD Decision Appversus usual care among 1650 English- or Spanish-speaking women to assess its effect on TOLAC and VBAC rates and decision quality.
Our hypotheses are that compared to women who receive only usual care, women who are randomized to use the Prior CD Decision App will be more likely to undergo TOLAC and have a VBAC; and will experience less decisional conflict, be more knowledgeable about TOLAC and ERCD and experience more optimal shared decision making.
