Predictors of 3-year mortality in subjects over 95 years of age. The NonaSantfeliu study.

Objectives: To examine the survival rates of subjects aged 95 or over after a follow-up period of 3 years, and to determine predictive factors for mortality risk.

Design: A prospective cohort study.

Setting: A community-based study.

Participants: Forty-eight subjects aged 95 or over.

Measurements: Sociodemographic data, Barthel Index, Lawton-Brody Index, Spanish version of the Mini-Mental State Examination, short version of the Mini Nutritional Assessment, comorbidity (Charlson Index), and prevalent chronic diseases were evaluated. Patients who died were compared with the rest.

Results: Thirty-six deaths (75%) were recorded during follow-up. The Cox multivariate analysis showed that lower Barthel Index scores and a history of heart failure were independently associated with long-term mortality.

Conclusions: In subjects aged 95 or over, poor functional status and history of heart failure were the two independent risk factors for 3-year mortality.
