Performance of Multihospital Health Systems' Flagship Hospitals in the CMS Star Rating Program

摘要

Using the Hospital Compare overall hospital quality star ratings and other publicly available data on acute care hospitals, we examined star ratings for the flagship hospitals of a set of multihospital health systems in the United States. We compared star ratings and hospital characteristics of flagship and nonflagship hospitals across and within 113 health systems. The system flagship hospitals had significantly lower star ratings than did nonflagship hospitals, and they did not generally have the highest star ratings in their own systems. Higher teaching intensity, larger bed size, higher uncompensated care, and higher disproportionate share hospital (DSH) patient percentage were all significantly associated with lower star ratings of flagship hospitals when compared with nonflagship hospitals across all health systems; the flagship hospital of a system was more likely to have the lowest star rating in its system if the difference in DSH percentage was relatively large between the flagship and nonflagship hospitals in that system.
