Two-Year Course of Quality of Life in Nursing Home Residents with Dementia

Abstract

To assess the course of quality of life (QoL) in nursing home residents with dementia and to study its predictors. This longitudinal, multicenter, observational cohort study with a 2-year follow-up looked at 290 residents with dementia, who lived in 14 dementia special care units in nine nursing homes in the Netherlands. QoL was assessed with the Qualidem, providing a total score and QoL profile with nine subscales. Residents were assessed at five assessments: every 6 months during 2 years. A linear mixed model was used for data analysis. No change was found in the Qualidem total score (range: 0-111) over 2 years. However, a significant increase of QoL over time was seen in the subscales "Care relationship," "Negative affect," "Restless tense behavior," "Positive self-image," "Social isolation," and "Feeling at home." A significant decrease of QoL was seen in the subscales "Positive affect," "Social relations," and "Having something to do." Most predictors of the course of Qol were found for the subscales "Positive self-image" (sex, Global Deterioration Scale, Severe Impairment Battery, Activities of Daily Living, and Neuropsychiatric Inventory) and "Having something to do" (Global Deterioration Scale, Severe Impairment Battery, and Activities of Daily Living). Sex and Neuropsychiatric Inventory at baseline were the predictors found most frequently. The total QoL score was stable over a 2-year period. However, QoL subscales showed multidirectional changes. The largest QoL decline in the subscale "Having something to do" suggests that more attention should be given to useful activities in nursing home care.
