نبذة مختصرة : Objectives: To verify the importance of Functional Independence Measure (FIM) on clinical outcomes in mechanically ventilated elderly and analyze risk factors associated with mortality. Methods: A prospective cohort of patients receiving IMV, divided into two groups: non survivor group - Hospital death and survivor Group - discharge. Results: FIM before admission to the ICU was on average for the non-survivor group 94.8 and for the surviving group 113.4 points (p=0.0062) and was associated with increased risk of death (p0.0001, RR=2.37, 95% CI=1.43-3.93). In the 27 patients evaluated after 6 months there was recovery of the FIM at approximate values (103.0 points) when compared to the moment before ICU admission (113.4). Conclusions: The reduction in FIM was associated with an increased risk of death. Mortality observed at admission was high at 59.0%. FIM suffered a significant reduction after admission to the ICU and 6 months after discharge from the ICU recovered to similar values when compared to before hospitalization. ; Objetivos: Verificar a importncia da medida da independncia funcional (MIF) nos desfechos clnicos de idosos mecanicamente ventilados e analisar os fatores de risco associados mortalidade. Mtodos: Coorte prospectiva de pacientes submetidos a VMI, divididos em dois grupos: Grupo no sobrevivente bito na internao e Grupo sobrevivente alta hospitalar. Resultados: A MIF antes da internao na UTI foi em mdia para o grupo no sobrevivente 94,8 e para o grupo sobrevivente 113,4 pontos (p=0,0062) e se relacionou com maior risco de bito (p0,0001; RR=2,37; IC 95%=1,43 a 3,93). Nos 27 pacientes avaliados aps 6 meses houve recuperao da MIF a valores prximos (103,0 pontos) comparados ao momento antes da internao na UTI (113,4). Concluses: A reduo da MIF relacionou-se com maior risco de bito. A mortalidade observada na internao foi alta com 59,0%. A MIF sofreu reduo significativa aps a internao na UTI e 6 meses aps a alta da UTI recuperou-se a valores semelhantes se comparada a antes da internao.
