THURSDAY, May 3 (HealthDay News) -- People diagnosed in the emergency room with a specific type of bleeding stroke should immediately be transferred to a hospital that treats at least 35 of these cases each year, according to new recommendations from the American Heart Association and the American Stroke Association.
Aneurysmal subarachnoid hemorrhage occurs when a weakened blood vessel within the brain ruptures, resulting in bleeding into the space around the brain.
Death rates within a month after this type of stroke were 39 percent in hospitals admitting fewer than 10 such patients each year, compared with 27 percent in hospitals treating more than 35 of these patients, according to an association news release.
