Official title
Effect of a Patient-Centered Decision App on TOLAC: An RCT
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Cesarean delivery (CD) is the most common inpatient surgery in the US, accounting for nearly one third of births annually. In the last decade, the CD rate has increased by approximately 50%, with almost 1.3 million procedures performed in 2012 (Hamilton 2013). CDs have been associated with an increase in major maternal morbidity (Silver 2010), with corresponding increases in length of inpatient care following delivery and frequency of hospital readmission (Lydon-Rochelle 2000). Organizations including Healthy People, the American College of Obstetricians and Gynecologists (ACOG), and the American College of Nurse Midwives have targeted reducing the CD rate as an important public health goal for more than a decade; however, identifying interventions to achieve this goal has proven challenging. Repeat CDs are a significant contributor to the increased cesarean rate, resulting from the combination of a rising rate of primary CD and a decreasing rate of vaginal birth after cesarean (VBAC), which declined from a high of 28.3% in 1996 (Guide 2010) to 9.2% in 2010 (Hamilton 2011). Why the VBAC rate has decreased so dramatically remains a subject of debate; the extent to which these changes are driven by patient preferences is not known. An NIH consensus conference statement noted that "the informed consent process for TOLAC and Elective Repeat Cesarean Delivery (ERCD) should be evidence-based, minimize bias, and incorporate a strong emphasis on the values and preferences of pregnant women," and recommended "interprofessional collaboration to refine, validate, and implement decision-making and risk assessment tools" to accomplish that goal (Cunningham 2010). Our group recently created a decision tool, which we refer to as the Prior CD App (PCDA), to help English- or Spanish-speaking TOLAC-eligible women delivering at hospitals that offer TOLAC consider individualized risk assessments, incorporate their values and preferences, and participate in a shared decision making process with their providers to make informed decisions about delivery approach. We are now conducting a randomized study of the effect of a Prior CD App on TOLAC and VBAC rates, as well as a number of aspects of decision quality.
