Only about 20% of people that have a cardiac arrest inside a hospital will survive. This statistic prompted the development of a Cardiac Arrest System of Care. Four out of five patients with cardiopulmonary arrest have changes in vital signs prior to the arrest. Therefore, most patients that eventually have a cardiac arrest showed signs of impending cardiac arrest. Survival rate could be improved if patients are identified and treated with ACLS protocols sooner.
Originally, specialized groups of responders within a hospital, called Cardiac Arrest Teams, attended to a patient with recognized cardiac arrest. These teams responded to a “Code Blue” after someone presumably recognized an active cardiac arrest and sought help. Many believed Cardiac Arrest Teams would improve patient survival, but results were disappointing. Studies show that survival rates were the same in hospitals with Cardiac Arrest Teams as in those without a team. As a result, hospitals are replacing Cardiac Arrest Teams with Rapid Response Teams (RRTs) or Medical Emergency Teams (METs).
Rather than waiting for loss of consciousness and full cardiopulmonary arrest, RRTs/METs closely monitor patients in order to treat patients before the cardiac arrest occurs. These teams combine the efforts of nurses, physicians, and family members to detect an impending cardiac arrest.
RRT/MET Alert Criteria
When hospitals implement RRTs/METs, there are fewer cardiac arrests, fewer ICU transfers, improved survival rates, and shorter length of inpatient stay.
