"Efforts to speed up patients' arrival at the hospital are absolutely crucial. We have very effective treatments, we just need to get patients to the hospital as fast as possible," says Lewis Morgenstern, M.D., senior author of the hospital study and first author of the school study. "Our first paper really speaks to the need to educate and motivate the public to call 911 for stroke, while the second shows one means to accomplish that goal."

Both studies are from a community-based research effort funded by the National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health. Researchers from the University of Texas at Houston and Eastern Michigan University are also involved.

The hospital study included 2,347 patients with ischemic (clot-based) strokes who reported to hospitals in the study area between January 2000 and June 2005. The average age was 71 years, and just over half were women. U-M stroke neurologist Jennifer Majersik, M.D., led the analysis.

The researchers reviewed medical records in detail, looking for information on what time each patient was last known to be without symptoms, and what time they reached the hospital. In some cases, when an exact time for the start of the symptoms was not known, the researchers used an estimate. They broke the patients up into groups by the time to presentation (arrival) at the hospital: less than three hours, three to six hours, six to 12 hours, and more than 12 hours.

The researchers also assessed how severe the patients' strokes were, and looked for differences in the time to hospital presentation for each severity group. The patients with the most severe strokes made it to the hospital in the fastest time, with nearly half of them making it in less than three hours. In contrast, only 28 percent of patients with the mildest level of stroke made it in that time. The study did not include patients who suffered transient is
