Cardiac Arrests in U.S. hospitals each year than previously estimated

Cardiac arrests; Significantly more patients suffer cardiac arrests in U.S. hospitals each year than previously estimated, according to new research in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal. Cardiac arrest, which occurs when the heart malfunctions and stops beating, is not the same as a heart attack; which occurs when blood flow to the heart is blocked.

Estimating Cardiac arrests

Researchers develop a model for estimating cardiac arrest incidence; so using data on facilities from the American Hospital Association annual survey, which include hospitals link to the American Heart Association’s Get With The Guidelines-Resuscitation (GWTG-R) registry. In 2011 when cardiac arrest data from the two registries was last analyze; so annual incidence was estimated to be 211,000 for adults and 6,000 in children.

The new study estimates that there are about 292,000 adult in-hospital cardiac arrests; also 15,200 pediatric in-hospital events (of which 7,100 cases were pulseless cardiac arrests and 8,100 cases; so in which there was a pulse but still requiring CPR) in the United States each year. Compare to previous reports, the public health burden of adult; also pediatric pulseless in-hospital cardiac arrest is approximately 38% and 18% greater than previously estimated.

“Our findings illustrate a concerning trend in U.S. hospitals; also show that cardiac arrest is a major public health problem,” said Lars W. Andersen, M.D., M.P.H., Ph.D., D.M.Sc., study co-author and associate professor at Aarhus University in Denmark, who oversaw the study as a visiting researcher; so at Beth Israel Deaconess Medical Center’s Department of Emergency Medicine in Boston.

“Previous incidence estimates may no longer reflect the current public health burden; hence of cardiac arrest in hospitalized patients across the U.S. Unfortunately; so the data does not provide an explanation for the increase in adult in-hospital cardiac arrest, but it is likely due to many factors; also may reflect an increase in actual events or in the reporting of cases over time.”

Basic life support

Andersen said the findings may suggest that basic life support; also advance cardiac life support training programs which traditionally have focus on out-of-hospital resuscitation may need to be expand; so to include potential in-hospital responders. Researchers found no indication that; so the number of pediatric events has increase over time. Instead, the current estimates are base on a larger database and provide the most robust; so estimate of pediatric in-hospital cardiac arrest cases in the United States to date.

In 2015, prevention of in-hospital cardiac arrest; which was add to the Chain of Survival in the American Heart Association’s Guidelines Update for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. Although preventing cardiac arrest is complex, possible steps to reduce in-hospital cases include educating more medical personnel; hence identifying deteriorating patients through early warning signs; also early intervention by rapid response and emergency response teams.

“It is also important to note that end-of-life discussions; also decisions are crucial in order to avoid attempts at resuscitation in patients where it is likely futile or against a patient’s wishes,” Andersen said. They also note that the findings should be interpret with caution as data was limit to data from GWTG-R hospitals.
