How to interpret the risk-adjusted mortality index
Our mortality scores take into account the severity of illness or injury.
A score of 1.0 means a hospital's survival rate is what would be expected given the severity of its patients' illnesses or injuries. The further below 1.0 the number is, the better job a hospital has done to save lives and provide safe, quality care.
Our scores for the past year (lower is better):
- .62 risk-adjusted mortality index for February 2015. Compared to other academic medical centers nationwide, this score ranks us in the top 8 percent for this important measure of patient outcomes.
- .68 risk-adjusted mortality index to date for the fiscal year. Compared to other academic medical centers nationwide, this score ranks us in the top 13 percent year-to-date.
Saving more lives
A low risk-adjusted mortality index is more than just a number. It means more patients were discharged from our hospital whose diagnoses and other health-related risk factors indicated they had a low likelihood of survival. This includes even severely ill or injured patients who were considered at high risk of death.

How is risk-adjusted mortality measured?
When a patient is discharged from our hospital, information about their stay (minus identifying information) is sent to University HealthSystems Consortium. The UHC is an alliance of academic medical centers that collects and reports data from its member hospitals. UHC looks at the patient's diagnosis upon admission to the hospital and other health-related factors which could affect the patient's outcome. These include previous medical history and chronic conditions. From this data, UHC estimates the risk of the patient dying during that hospitalization and compares it to the patient's actual outcome.
Each month, we receive data from UHC comparing the number of actual deaths in our hospital to their estimated number of expected deaths. The more our actual number is below the expected number, the better job our hospital has done to save lives and provide safe, quality care.
