HOSPITAL DEFIBRILLATOR USE APPEARS SLOW
January 3, 2008
About half a million patients suffer cardiac arrest inside a U.S. hospital each year. Less than a third survive. In many cases, a medical device called a defibrillator can restart a stopped heart by delivering an electrical shock, but only if it is used quickly. Since 1991, the American Heart Association has recommended that hospitals be ready to shock a stopped heart within two minutes after detecting cardiac arrest.
However, American hospitals frequently take too long to restart stopped hearts after cardiac arrest, according to a study published in the New England Journal of Medicine.
Other major findings:
- In 30 percent of cardiac-arrest episodes, hospitals waited longer than two minutes, leading to more deaths.
- Between 2000 and 2005, only 70 percent of patients received a shock within the recommended two minutes; for those patients, the chances of leaving the hospital alive were 39 percent.
- About 17 percent of the patients were shocked in the third through the fifth minute; for them, the survival rate was 28 percent and when hospitals took longer than five minutes to shock a patient, the survival rate fell to 15 percent.
- Facilities with fewer than 250 beds did worse than larger ones, the study found and the participating hospitals were about 23 percent more likely to be tardy in shocking a black patient than a white one.
Dr. Paul Chan of the University of Michigan and lead author of the study suggested the following ways to improve the statistics:
- Allowing nurses to administer shocks with manual defibrillators, installing automated defibrillators that anybody can use.
- Expanding use of automated monitoring systems that detect cardiac arrest.
