Evaluating a midwife-led model of antenatal care for women with a previous caesarean section: a retrospective, comparative cohort study

Abstract

Background: Research is yet to identify effective and safe interventions to increase the vaginal birth after cesarean (VBAC) rate. This research aimed to compare intended and actual VBAC rates before and after implementation of midwife-led antenatal care for women with one previous cesarean birth and no other risk factors in a large, tertiary maternity hospital in England.

Methods: This was a retrospective, comparative cohort study. Data were collected from the medical records of women with one previous lower segment cesarean delivery and no other obstetric, medical, or psychological complications who gave birth at the hospital before (2008) and after (2011) the implementation of midwife-led antenatal care. Chi-squared analysis was used to calculate the odds ratio, and logistic regression to account for confounders.

Results: Intended and actual VBAC rates were higher in 2011 compared with 2008: 90 percent vs. 77 percent, adjusted odds ratio (aOR) 2.69 (1.48–4.87); and 61 percent vs. 47 percent, aOR 1.79 (1.17–2.75), respectively. Mean rates of unscheduled antenatal care sought via the delivery suite and inpatient admissions were lower in 2011 than 2008. Postnatal maternal and neonatal safety outcomes were similar between the two groups, except mean postnatal length of stay, which was shorter in 2011 compared with 2008 (2.67 vs. 3.15 days).

Conclusions: Implementation of midwife-led antenatal care for women with one previous cesarean offers a safe and effective alternative to traditional obstetrician-led antenatal care, and is associated with increased rates of intended and actual VBAC.
