TUESDAY, July 10 (HealthDay News) -- Although prompt medical treatment is essential for people experiencing a stroke, hospitals aren't notified about incoming stroke patients in about one-third of cases, two new studies find.
The failure of emergency medical services (EMS) personnel to alert hospitals adds precious minutes on to how long it takes to diagnose stroke patients and administer clot-busting drugs, according to researchers.
Experts from the American Heart Association/American Stroke Association advised EMS to notify hospitals about incoming stroke patients so preparations can be made for their timely evaluation and treatment.
In the studies, researchers examined about 372,000 cases of acute ischemic stroke (caused by a blocked blood vessel to the brain) between 2003 and 2011. The patients were taken by ambulance to one of nearly 1,600 hospitals participating in a quality improvement program -- called "Get with The Guidelines-Stroke" -- launched by the heart/stroke associations.
One study, published in Circulation: Cardiovascular Quality & Outcomes, found that when EMS alerted hospitals about incoming stroke cases, the patients were diagnosed and treated more quickly.
Fast diagnosis and treatment is critical because certain clot-busting drugs have to be given within 3 to 4.5 hours after the onset of stroke symptoms to be effective, according to the study.
But a second study found that EMS pre-notification of stroke patients happened in only 67 percent of stroke cases in 2011, a slight increase from 2003 when hospitals were notified in about 58 percent of cases.
That study is published in the Journal of the American Heart Association.
"Despite national guidelines recommending pre-notification by EMS for acute stroke patients, it's disappointing that there's been little improvement," the senior author of both studies, Dr. Gregg C. Fonarow, a professor of cardiovas
