Out-of-hospital XXXX in the elderly: A large-scale population-based study.

@entity1 @entity1167
BACKGROUND: There is little information on elderly @entity1 who suffer from out-of-hospital @entity1167 (OHCA). AIM: To determine 30-day mortality and neurological outcome in elderly @entity1 with OHCA. METHODS: OHCA @entity1 >=  70 years of age who were registered in the Swedish Cardiopulmonary Resuscitation Register between 1990 and 2013 were included and divided into three age categories (70-79, 80-89, and >=  90 years). Multiple logistic regression analyses were performed to identify independent predictors of 30-day survival. RESULTS: Altogether, 36,605 cases were included in the study. Thirty-day survival was 6.7% in @entity1 aged 70-79 years, 4.4% in @entity1 aged 80-89 years, and 2.4% in those over 90 years. For @entity1 with witnessed OHCA of cardiac aetiology found in a shockable rhythm, survival was higher: 20%, 15%, and 11%, respectively. In 30-day survivors, the distribution according to the cerebral performance categories (CPC) score at discharge from hospital was similar in the three age groups. In multivariate analysis, in @entity1 over 70 years of age, the following factors were associated with increased chance of 30-day survival: younger age, OHCA outside the home, witnessed OHCA, CPR before arrival of EMS, shockable first-recorded rhythm, and short emergency response time. CONCLUSIONS: Advanced age is an independent predictor of mortality in OHCA @entity1 over 70 years of age. However, even in @entity1 above 90 years of age, defined subsets with a survival rate of more than 10% exist. In survivors, the neurological outcome remains similar regardless of age.
