Collaborative practice model: Madigan Army Medical Center.

In 2007, Madigan Army Medical Center implemented a new maternity care delivery model, integrating obstetricians and certified nurse-midwives (CNMs) in a collaborative practice. The change was driven by multiple factors, including patient preference, changes in the resident workweek, and low provider satisfaction. This article describes the elements of successful collaboration, including the structure, effective teamwork principles, role of the CNM in resident education, and preliminary data on mode of delivery, the number of CNM-supervised resident births, and procedures, such as episiotomy and epidural use.
