ObjectiveTo define the prognostic factors related with mortality of patients who suffer cardiorespiratory arrest (CRA) in the hospital, according to Utstein style guidelines.DesignA descriptive and prospective study covering a 30-month consecutive period of all the patients who suffered at least one episode of in-hospital CRA. A Cox regression multivariate analysis was made to identify the independent factors associated with mortality.SettingA medical-surgical center in Hospital "Virgen de las Nieves" (HUVN), Granada (Spain).PatientsAll the patients attended due to CRA in the hospital, except for those occurring in the operating and recovery room areas. They were followed-up to hospital discharge.Main VariablesMortality on hospital discharge.Results203 patients who suffered at least one cardiorespiratory arrest in the hospital, with a median age of 67 years and preponderance of male (60.6%). The most common location was in intensive care medicine unit (48%) and cardiac etiology (62%). Hospital survival rate was 23.15%. In multivariate analysis, strong predictors of mortality were administration of any dose of epinephrine during resuscitation maneuvers (OR 3.4; CI 95%. 1.6-7), total duration of resuscitation (HR 1.018; CI 95%, 1.012-1.024) and as protective factors the first ventricular fibrillation/ventricular tachycardia rhythm with no pulse (HR 0.6; CI 95%, 0.4-0.9) and witnessed by a doctor (HR 0.6; CI 95%, 0.5-0.9).ConclusionsThe type of witness was identified among the predictors of mortality on hospital discharge after an episode of cardiac arrest. This becomes important because the qualification of healthcare personnel can be improved through adequate training.Copyright 2008 Elsevier España, S.L. y SEMICYUC. All rights reserved.
