Abstract

in English, Spanish

BACKGROUND:

Frailty in elderly results from impaired physiological reserve in multiple systems. Establishing if frail elderly inpatients develop more functional impairment at discharge, will allow the development of strategies for preventing or limiting the deterioration in this vulnerable group.

METHODS:

Prospective cohort in 133 elderly inpatients. At admission, frailty, functional status, comorbidity and comprehensive geriatric evaluation were determined. The main outcome was functional state at hospital discharge.

RESULTS:

64 patients presented frailty (48.1%) and 69 did not present that state (51.9%), with a mean age of 73 and 68 years, respectively. Mean decrement in functional state at discharge was -8.06 % (IC 95 % -10.38 to -5.74), from 97.97 % to 89.91 % (p < 0.001) in patients who did not present frailty, and -21.18 % (IC 95 % -24.97 to -17.38), from 87.52 % to 66.34 % (p < 0.001) in frail patients. The difference between groups at discharge was -14.37 % (IC 95 % -16.80 to -11.94, p < 0.001) to the detriment of the frail. Frailty was associated with functional impairment in the univariated and multivariated analysis, beta -13.11 % (IC 95 % -17.45 to -8.78, p < 0.001) and beta -17.27 (IC 95 % -23.27 to -11.28, p < 0.001), respectively. In the final model, frailty (beta -14.73, IC 95 % -19.39 to -10.07, p < 0.001) and cognitive impairment (beta -8.19, IC 95 % -15.28 to -1.10, p = 0.024) predict functional decrement.

CONCLUSION:

Frailty independently predicts functional impairment at hospital discharge.
