The review seeks to compare models of centralized and decentralized care. Increasingly since 1990, centralization of care has been the backdrop of studies regarding decentralized models. Moreover, this review seeks to compare models of care in their ability to provide safe, high quality, cost effective perinatal surgical care to rural women specifically, and so rural health was a required search subject.
