Prehospital Predictors of Survival in Patients with Out-of-Hospital Cardiac Arrest

Background and Objectives: Despite advances in the treatment of heart diseases, outcome patients experiencing sudden cardiac arrest remains poor. The aim our study was to determine prehospital variables as predictors survival outcomes out-of-hospital (OHCA) victims. Materials Methods: This a retrospective observational cohort OHCA cases. EMS protocols created accordance with Utstein style reporting for OHCA, first responder intervention reports, medical dispatch center hospital reports were all reviewed. Multivariate logistic regression performed following variables: age, gender, witnessed status, location, bystander CPR, rhythm, etiology. Results: A total 381 interventions resuscitation attempts analyzed. In more than half (55%) them, CPR performed. Thirty percent achieved return spontaneous circulation (ROSC), 22% those 30-day (7% victims), 73% survived Cerebral Performance Score 1 or 2. model adjustment confirms that shockable initial rhythm predictor ROSC [OR: 4.5 (95% CI: 2.5–8.1)] 9.3 2.9–29.2)]. Age also associated (≤67 years) 3.9 1.3–11.9)] better survival. Conclusions: Elderly have lower rate. occurrence alarmingly low. Shockable is rate neurological compared non-shockable rhythm.
