Including Stroke Severity in Risk Models Improves Mortality Prediction

Adding stroke severity to a hospital 30-day mortality model based on claims data for Medicare beneficiaries with acute ischemic stroke was associated with 1) improvement in predicting the risk of death at 30 days and 2) changes in performance ranking regarding mortality for a considerable proportion of hospitals, according to a new study whose authors include two University of Cincinnati (UC) neurologists.

The study is published in the July 18, 2012, issue of JAMA: The Journal of the American Medical Association. Authors include Joseph Broderick, MD, Albert Barnes Voorheis Chair and professor of neurology at UC, and Dawn Kleindorfer, MD, professor and division director of cerebrovascular disease at UC. Both are members of the UC Gardner Neuroscience Institute. The study was led by Gregg Fonarow, MD, of the University of California, Los Angeles.
