ObjectiveTo compare the functional capacity of younger elderly individuals (60 to 79
years old) with that of older elderly individuals (≥ 80 years old)
during the first 6 months after discharge from the intensive care unit.MethodsA multicenter prospective cohort study was conducted, in which data on
intensive care unit admission and outcomes after hospital discharge
(immediate post-discharge, after 3 months and after 6 months) were
collected. Muscle strength was evaluated through the protocol of the Medical
Research Council and dynamometry (handgrip); the ability to perform
activities of daily life and functional independence were assessed by the
Barthel index and the usual level of physical activity (International
Physical Activity Questionnaire); and quality of life was assessed by the
12-Item Short-Form Health Survey Version 2.ResultsAmong the 253 patients included, 167 were younger elderly (between 61 and 79
years old), and 86 were older elderly (≥ 80 years old). During the
sixth month of evaluation, the older elderlies presented a higher need for a
caregiver (69.0% versus 49, 5%, p = 0.002). Functional
capacity prior to intensive care unit admission and in the third month after
discharge was lower in older elderlies than in younger ones (Barthel prior
to the intensive care unit: 73.0 ± 30.0 versus 86.5
± 22.6; p <0.001, Barthel in the third month: 63.5 ± 34.0
versus 71.5 ± 35.5, p = 0.03), as was the usual
level of physical activity (International Physical Activity Questionnaire in
the third month: active/very active 3.4% versus 18.3%, no
physical activity 64.4% versus 39.7%, p < 0.001, and
International Physical Activity Questionnaire in the sixth month:
active/very active 5.8% versus 20.8%, no physical activity
69.2% versus 43.4%, p = 0.005). Older elderlies had lower
muscle strength when assessed according to handgrip in both the dominant
(14.5 ± 7.7 versus 19.9 ± 9.6, p = 0.008) and
non-dominant limb (13.1 ± 6.7 versus 17.5 ±
9.1, p = 0.02). There were no differences in functional capacity loss or
reported quality of life between the age groups.ConclusionAlthough there were great functional capacity losses after discharge from the
intensive care unit in both age groups, there was no difference in the
magnitude of functional capacity loss between younger (60 to 79 years) and
older elderly individuals (≥ 80 years old) during the first 6 months
after discharge from the intensive care unit.
