Quality of life among elderly patients with dementia in institutions.Dement Geriatr Cogn Disord. 2011; 31(6):435-42.DG
To study quality of life among the elderly with dementia in institutions.
Patients above 60 years with dementia, 82 in nursing home and 74 in departments of geriatric psychiatry, were included. They were assessed with the Quality of Life in Late-Stage Dementia (QUALID); the Self-Maintenance scale, Mini Mental State Examination (MMSE) and Clinical Dementia Rating scale. Patient's age, gender, previous medical and psychiatric history were recorded. Dementia was diagnosed according to ICD-10 criteria for research. Based on information in an interview with the patient and a carer and information in the patient's record, a geriatric psychiatrist made a diagnosis of major depression according to DSM-IV, if present.
The patients' mean (± SD) age was 82.9 ± 7.7 years, 103 (66%) were women. A factor analysis of the QUALID scale resulted in two factors: 'discomfort' and 'comfort'. Three linear regression analyses were performed. Variables associated with lower quality of life (total QUALID score) were: a diagnosis of major depression (p < 0.001), lower score on MMSE (p = 0.032), impaired function in activities of daily living (p = 0.007) and female gender (p = 0.046). Variables associated with the 'discomfort' subscale score were: major depression (p < 0.001), lower score on MMSE (p = 0.006) and living in a department of geriatric psychiatry (p = 0.041). The 'comfort' subscale score was associated with impaired function in activities of daily living (p < 0.001). Explained variance for the three models was 34, 33 and 23%, respectively.
Quality of life is diminished among elderly patients in institutions and the most marked correlates were a diagnosis of major depression, worse performance in activities of daily living and worse cognitive function.
