The index considers several important factors, such as a patient’s medical problems and the severity of those problems. Patients who are very sick when they arrive will have a higher risk of mortality, while patients who are less sick when they arrive will have a lower risk of mortality.
A mortality index of 1.0 means the actual number of deaths equals the average number of deaths among peer hospitals. An index of less than 1.0 means fewer patients died than in the database, so a lower score is better.
