Objective : The purpose of this study was to collect preliminary data on the feasibility of a prospective, observational study of maternal and neonatal outcomes associated with planned vaginal and planned Cesarean delivery. Methods : A convenience sample of women presenting for planned vaginal or Cesarean delivery at term was collected May-October, 2007. Women were asked their willingness to participate in a theoretical study of planned vaginal or Cesarean delivery, including option of a tissue biopsy and long-term follow-up. Data on maternal and neonatal complications, hospital costs, and satisfaction was compared between groups using chi-square, Mann-Whitney U, and t-tests. Results : Of the 185 women enrolled, 84% agreed to participate in the proposed study (45% with the vaginal biopsy and an additional 39% if the biopsy was excluded) while 74% agreed to be followed long- term. There was no difference in satisfaction according to method of delivery. Women planning Cesarean delivery were more likely to report abdominal pain (p=0.010) and less vaginal pain (p=0.011). Infants born by Cesarean delivery were more likely to need resuscitation (p<0.001) or have pulmonary complications (p=0.02) but were less likely to be injured during delivery (p=0.042). Planned Cesarean delivery was associated with higher direct costs for the mother (p=0.005) and for the baby (p=0.017). Conclusions : Women appear willing to participate in a prospective, observational study of planned vaginal versus planned Cesarean delivery, and sample size calculations should overestimate enrollment by approximately 15-25%. These data may provide effect size estimates for future prospective studies of mode of delivery
