Updated Variable-Radius Measures of Hospital Competition (original) (raw)

This research builds on previous studies of hospital market definitions by adopting a circular market model that captures the majority of a hospital's patient population. By calculating variable radii for hospitals across several states and predicting these measurements for all nonfederal, short-term general hospitals in the continental US, it investigates the impact of competition within these defined markets using metrics such as the number of hospitals and the Herfindahl-Hirschman index (HHI) for competition assessment. Results demonstrate varying competition levels influenced by geographical and operational factors including hospital size, service offerings, and adjacency to metropolitan areas.
