Abstract
This survey was carried out to explore the relationship between symptoms and functional status in the elderly living at home. The setting is an urban area of Turin (Northern Italy). A cross-sectional screening for 20 symptoms was completed in 747 subjects, aged 75 and older. Dependence in basic Activities of Daily Living (ADL) and in Instrumental Activities of Daily Living (IADL), Short Portable Mental Status Questionnaire and Cumulative Illness Rating Scale were also ascertained. A discriminant analysis was performed to determine the potential value of symptoms in predicting functional impairment. The mean number of symptoms was 6.0 per subject (±S.D. 3.3) and dependence in ADLs was 8.2%. Amongst a 20-symptom list, six symptoms (fatigue, memory loss, indigestion, nutrition, hearing and speaking problems), either alone or in association, showed sufficient discriminatory power to identify dependence in ADLs (sensitivity=72%), mental impairment (72%), psychological distress (80%), but not dependence in IADLs (48%). Symptoms are common in the free-living elders, but their functional status is good. A short (6 items) formal screening for symptoms may be a simple way to predict functioning and to rapidly manage problems.
