Outline of Final Research Achievements

Using Japanese nationwide registry for out-of-hospital cardiac arrest (OHCA), we have developed a termination-of-resuscitation (TOR) rule in the field for patients with refractory OHCA, including the resuscitation duration by emergency medical services (EMS) personnel. The developed TOR rule is as follows: EMS personnel could consider termination of resuscitation in the field if patients meet all 3 of following criteria; (1) unwitnessed arrest (2)initial non-shockable rhythm, and (3) no return of spontaneous circulation after 15 minutes of EMS-initiated cardiopulmonary resuscitation. The specificity and positive predictive value for predicting 1-month death in patients who met these 3 criteria were 99.1% and 98.8%, respectively. Implementation of this TOR rule would have reduced the percentage of patients transported to the emergency department, approximately 9%, and the number of attendant hazards to EMS personnel, and have improved the utilization of hospital healthcare resources.
