Functional homeostasis is the ability of an individual to withstand illness without loss of function.
We investigate whether the level of functional homeostasis predicts adverse outcomes in the 6 months posthospital discharge in older men and women.
A prospective cohort study was conducted in an acute care geriatric inpatient unit of a university hospital.
Subjects included a consecutive series of patients admitted to the unit.
The Functional Independence Measure (FIMTM) instrument was used to assess patients at four time points : preillness, hospital admission, hospital discharge, and 6 months postdischarge.
Of the 122 subjects available for analysis, 64 (52%) experienced a decline in functional level from preillness to hospital discharge and were defined as having poor functional homeostasis, whereas 58 (48%) experienced no change or an increase in functional status and were defined as having good functional homeostasis.
Those with poor functional homeostasis had a higher 6-month readmission rate to the hospital (59.4 v 39.7% ; P=0.03) and a higher rate of any adverse outcome (78.1 v 50% ; P=0.001) than those with good functional homeostasis.
In logistic regressive analyses, functional homeostasis remained a significant and powerful predictor of adverse outcomes independent of actual level of function at discharge, age, gender, living status, and other factors that might influence outcomes. (...)
