Risk Adjusted Mortality (O/E) Ratio
<p>The risk-adjusted mortality O:E ratio is observed deaths/expected deaths (1.0 represents the average mortality rate; < 1.0 represents a better-than-expected mortality rate). The O:E ratio is a commonly used method of representing care and making data comparisons. Vizient data are used in this calculation to make effective comparisons. The institute’s O:E ratio remains well below expected. The population is defined as all patients admitted to the Medicine Institute’s service.</p>
