For CABG patients, the 100 Top hospitals had an average mortality index of 0.79 and an average complications index of 0.93, compared with 1.16 and 1.21 for all other hospitals in the study group. Average length of stay and cost are also lower at the 100 Top hospitals. HCIA collects, manages, and distributes comparative healthcare information. HCIA provides decision support systems to more than 1,500 hospitals, as well as many of the largest U.S. health insurance companies and managed care organizations for the purpose of measuring clinical outcomes and managing the medical costs of populations. Hospitals with the most significant decrease between expected and observed received the highest rankings.
Favorable values are lower.
HCIA compared the predicted number of complications with the observed number. Favorable values are lower. There is strong evidence supporting better outcomes as volumes increase. The actual ranking was based on patient volume within the hospital's region. Favorable values are higher.
