Variation in primary cesarean delivery rates by individual physician within a single-hospital laborist model.

Background: Laborist practice models are associated with lower rates of cesarean delivery than individual private practice models in several studies; however, this effect is not uniform. Further exploration of laborist models may help us better understand the observed decrease in rates of cesarean delivery in some hospitals that implement a laborist model.

Objective: Our objective was to evaluate the degree of variation in rates of primary cesarean delivery by individual laborists within a single institution that uses a laborist model.
