%0 Report %A Fischer, Stefanie %A Royer, Heather %A White, Corey %T Health Care Centralization: The Health Impacts of Obstetric Unit Closures in the US %D 2023 %8 2023 Mar %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 15987 %U https://www.iza.org/index.php/publications/dp15987 %X Over the last few decades, health care services in the United States have become more geographically centralized. We study how the loss of hospital-based obstetric units in over 400 counties affect maternal and infant health via a difference-in-differences design. We find that closures lead mothers to experience a significant change in birth procedures such as inductions and C-sections. In contrast to concerns voiced in the public discourse, the effects on a range of maternal and infant health outcomes are negligible or slightly beneficial. While women travel farther to receive care, closures induce women to receive higher quality care. %K maternity ward %K maternal health %K infant health %K closure %K obstetric %K hospital quality
