Mortality rates are a measure of how many people die while receiving care in the hospital. The University of Chicago Medicine reports risk-adjusted mortality rates in comparison to the expected mortality rates for an academic medical center such as ours. Risk-adjusted mortality rates account for the severity of illness or injury, as some hospital deaths are not preventable.
The University of Chicago Medicine consistently rates well for risk-adjusted mortality, and scores below the expected mortality rate for academic medical centers, as reported by the University HealthSystem Consortium. A score of 1.0 means the hospital's survival rate is as expected, given the severity of illness or injury of its patients. Scores below 1.0 indicate that a hospital is performing better than expected--demonstrating that adherence to quality care practices saves lives.
