Dispersion in the hospital network of shared patients is associated with less efficient care.
The purpose of this study was to examine the level of distribution of patient-sharing networks across U.S. hospitals and its relationship with 3 measures of care delivered by hospitals that were likely to relate to coordination. The researchers utilized data from 2016 Medicare Fee-for-Service claims to measure the volume of patients that hospitals treated in common, and then calculated a measure of dispersion for each hospital. The relationship between network dispersion, Medicare spending per beneficiary, readmission rates, and emergency department (ED) throughput rates were then estimated. The study reported that hospitals with more dispersed networks had greater spending rates but not higher admission rates or slower ED processes. Among hospitals with less resources, more dispersion was associated with higher readmission rates and slower ED processes. The researchers concluded that dispersed interhospital networks create difficulties in coordinating patients who are treated at multiple hospitals, and that the structure of patient-sharing networks may be an overlooked factor that influences the delivery of care in health care organizations.
