  • Background: The rate of survival to hospital discharge is less than 10% for out-of-hospital cardiac arrest (OHCA). Aim: To develop and implement a Chilean prospective, standardized cardiac arrest registry following the Utstein criteria. Material and Methods: We conducted a prospective registry for patients presenting at an urban, academic, high complexity emergency department (ED) after having an OHCA. The facility serves approximately 10% of the national population. Data were registered and analyzed following the Utstein criteria for reporting OHCA. Results: For three years, 289 patients aged 59 ± 19 years (63% men) were included. Fifty seven percent of patients were taken to a health care facility for the first medical assessment by relatives or witnesses and 34% was assisted and transferred by prehospital personnel. In the subgroup of non-traumatic OHCA, 28% (n = 54) received bystander cardiopulmonary resuscitation (CPR). The registered cardiac rhythms were asystole (61%), pulseless electrical activity (PEA) (25%) and ventricular tachycardia (VT) or ventricular fibrillation (VF) (11%). The overall survival rate to discharge from the hospital was 10%, while survival with mRankin score 0-1 was 5%. The median hospitalization length of stay was 18 days among those who survived, compared with five days for the group of patients that died during the hospital stay. Conclusions: OHCA is an important cause of death in Chile. The development of a national registry that follows the International Liaison Committee on Resuscitation guidelines is the first step to assess the profile of OHCA in the region. It will provide crucial information to identify prognostic factors and variables that can help develop standards of care and set up the basis to optimize cardiac arrest management within our country and region.
