Does the Inclusion of Stroke Severity in a 30-Day Mortality Model Change Standardized Mortality Rates at Veterans Affairs Hospitals

The small number of stroke admissions and the narrow range of 30–day stroke mortality rates at the facility level in the Veterans Health Administration cast doubt on the value of using 30–day RSMRs as a means of identifying outlier hospitals based on their stroke care quality.
