Special acute care unit for older adults with Alzheimer's disease

Abstract

To describe the cognitive, functional, and nutritional features of patients admitted to a Special Acute Care Unit (SACU) for elderly patients with Alzheimer's disease (AD). One-year observational study of patients with AD and other related disorders hospitalized in the SACU, Department of Geriatrics, Toulouse university Hospital during 2005. A comprehensive neurocognitive and non-cognitive geriatric assessment was performed. Data on full clinical evaluation, nutritional status, activities of daily living (ADL), gait and balance disturbance, behavioural and psychological symptoms (BPSD), and sociodemographics were recorded. Four-hundred and ninety-two patients were assessed. Their mean age was 81.1+/-7.7, the mean length of stay was 10.7+/-6.3 days, 62% were female, 63.9% were admitted from their own home and 30.4% from a nursing home. Eighty percent of patients had probable Alzheimer's disease or mixed dementia, less than 20% had other causes of dementia. Results of their comprehensive assessment showed a mean mini-mental state examination of 14.5+/-7.4; a mean total ADL score of 3.7+/-1.7. Seventy-seven percent had gait or balance disturbances; 90% of patients presented an unsatisfactory nutritional status. The most common reason for admission was BPSD. AD complications are responsible for many acute admissions. Elderly patients suffering from dementia represent a population with unique clinical characteristics. Further randomised clinical trials are needed to evaluate the effectiveness of Special Acute Care Units for patients with AD and other related disorders.
