Introduction:

The state of frailty is a syndrome, characterized by decreased resistance and physiological reserves of the elderly. It is related to the occurrence of adverse health effects such as: falls, disability, hospitalization, institutionalization and death.

Objectives:

To determine prognostic factors for mortality in frail elderly patients.

Method:

Longitudinal type and observational study, developed from December 2017 to November 2018. The sample consisted of 50 frail elderly, who were admitted to the Internal Medicine service of the Hospital Militar Central "Dr. Carlos J. Finlay" and were followed for 12 months afterwards of having been discharged.

Results:

Mortality was in the order of 62% (CI = 48-76). After logistic regression and adjusting for age and sex, independent variables were associated with mortality in frail elderly people: disability (OR = 13), poor health self-assessment (OR = 6.5) and cognitive impairment (OR = 4.3).

Conclusions:

The results of this study provide strong evidence to support the use as predictors of mortality in frail elderly people, the presence of cognitive impairment, disability and poor health self-perception.
