Variation in rates of hospital admission from the emergency department among Medicare patients at the regional, hospital, and physician levels.
Rates of admission from the emergency department (ED) vary widely across regions of the country, hospitals within regions, and physicians within hospitals. The study objective was to determine the extent to which variation in admission decisions was described by differences in admission rates at these 3 levels. The investigators concluded that within-area variation, both across hospitals within a region and across physicians within a hospital, was a more substantial component of observed variation in admission rates from the ED than regional level variation.
