Evolution of functional capacity of older people during hospital stay

Background: Up to 70% of hospitalized older people experience a deterioration of their functional capacity during the course of hospital stay. This change has a dismal effect of quality of life and prognosis. Aim: To assess the change in functional status of older people during the course of hospitalization in a geriatric unit. Material and Methods: Review of medical records of 83 patients with a mean age of 79 years (70% women), hospitalized in an acute geriatric unit of a clinical hospital, between 2007 and 2009. Functional capacity was assessed using Barthel and Lawthon scales in a basal period, on admission and on discharge. Results: Mean hospital stay was nine days. Median scores of Barthel scale on the basal period, on admission and on discharge were 90, 50 and 80, respectively. The figures for Lawthon scale were 4,2 and 3 respectively. Seventy eight percent of patients lost functional capacity during hospital stay and 72% recovered their functional status on discharge. Conclusions: A great proportion of older people experience a loss of functional capacity during hospitalization. This deterioration can be reverted with an adequate geriatric management.
