The changing landscape of perinatal regionalization.

Regionalization, which emphasizes matching patient needs with the capabilities of the hospital in which care is provided, has long been a recommended approach to reducing neonatal morbidity and mortality. Over the past decade, research methods surrounding the measurement and evaluation of such programs have improved, thus strengthening arguments for implementation of these strategies. However, regionalization policies vary widely across regions and between countries, with potential impacts on neonatal outcomes as well as costs of care. It is important to account for geographic and other regional differences when determining the feasibility of regionalization for a specific region, as certain areas and populations may need particular consideration in order for regionalization policies to be successful.
