[Predictors factors about functional decline in community-dwelling older persons].
OBJECTIVE
The goal of this work was to prove the usefulness of simple standard geriatrics tools as a predictors of basic daily activities or quality of life decline in one year in older patients apparent healthy to apply in primary care.


METHODS
Prospective study of a randomised sample of 100 patients.


METHODS
Urban primary care center.


METHODS
A systematic sample of 100 patients of 75 years old or older, with Barthel index > or =90, Karnofsky scale > or =70 and without any neoformation process evaluated prospectively.


METHODS
A comprehensive geriatric assessment was done that include: physical performance, neural-psychologist performance, organic assessment, social assessment. After 12 month were assessed again basic activities of daily living (Barthel) and quality of life (Karnofsky). To estimate the odds ratio (OR) of association we used logistic regression models.


RESULTS
The alterations in cognition trials (Pfeiffer >2) and in instrumental activities of daily living (Lawton <7) showed predictors about decline in basic activities of daily living (OR=4.66; CI, 1.33-16.22), (OR=4.89; CI, 1.65-14.48). The alterations in instrumental activities of daily living (Lawton <7) and in performance tests (abbreviated Guralnik test <4) showed predictors about decline in quality of life (OR=4.31; CI, 1.62-11.44), (OR=7.41; CI, 1.54-35.62).


CONCLUSIONS
In primary care geriatric assessment tools based in instrumental activities of daily living, cognition and performance tests predict decline in basic activities of daily living and quality of life.
