Mortality ratio. The number of patient deaths (mortality) in a hospital is shown as a mortality ratio that compares patients' actual mortality rates to their expected rate of mortality. The observed-to-expected mortality rate is a risk-adjusted measure of a hospital's mortality rate. This ratio is created from two sets of numbers: 1  Observed mortality. 2  The actual number of patients that died in the hospital each month. 3  Expected mortality.
