RESUMO
OBJECTIVE: Laborist programs have expanded throughout the United States in the last decade. Meanwhile, there has been no published research examining their effect on patient outcomes. Cesarean delivery is a key performance metric with maternal health implications and significant financial impact. Our hypothesis is that the initiation of a full-time dedicated laborist staff decreases cesarean delivery. STUDY DESIGN: In a tertiary hospital staffed with private practice physicians, data were retrospectively reviewed for 3 time periods from 2006 through 2011. The first period (16 months) there were no laborists (traditional model), followed by 14 months of continuous in-hospital laborist coverage provided by community staff (community laborist), and finally a 24-month period with full-time laborists providing continuous in-hospital coverage. The primary hypothesis was that full-time laborists would decrease cesarean delivery rates. RESULTS: Data from 6206 term nulliparous patients were retrospectively reviewed. The cesarean delivery rate for no laborist care was 39.2%, for community physician laborist care was 38.7%, and for full-time laborists was 33.2%. With adjustment via logistic regression, full-time laborist presence was associated with a significant reduction in cesarean delivery when contrasted with no laborist (odds ratio, 0.73; 95% confidence interval, 0.64-0.83; P < .0001) or community laborist care (odds ratio, 0.77; 95% confidence interval, 0.67-0.87; P < .001). The community laborist model was not associated with an effect upon cesarean delivery. CONCLUSION: A dedicated full-time laborist staff model is associated with lower rates of cesarean delivery. These findings may be used as part of a strategy to reduce cesarean delivery, lower maternal morbidity and mortality, and decrease health care costs.
