Outcome of elderly patients requiring ventilatory support in intensive care.

The objectives of the study were: 1) to evaluate mortality in elderly patients requiring ventilatory support in Intensive Care Unit (ICU) and at 6, 12 and 18 months after discharge from ICU; 2) (main objective) to determine predictors of mortality in ICU and after discharge; and 3) to assess the life-style of survivors. One hundred and ten consecutive hospitalized patients > or = 70 years were included in this retrospective study. Follow-up evaluation was conducted by telephone interview. Mortality in ICU and after discharge was the outcome variable. Fifteen parameters were recorded at admission and during hospitalization. Residence, health status, and self-sufficiency were evaluated after discharge. 1) Mortality in ICU and at 6, 12 and 18 months after discharge was 38%, 60%, 63% and 67% respectively. 2) The predictors of mortality in ICU were admission in shock, and use of major therapeutic interventions. Predictors of mortality at 6 months were admission in shock, previous impaired health status and marital status. 3) Eighteen months after discharge 92% of the surviving patients (N = 33) had the same residence, 75% had the same health status, and 78% had the same autonomy compared with pre-admission status. We concluded that shock and previous health status but not age are predictors of short- and long-term prognoses in elderly patients hospitalized in ICU for mechanical ventilation.
