Does Cognitive Impairment Infl uence Quality of Life Among Nursing Home Residents

Purpose: We investigated the relationship between cognitive status and quality of life (QOL) of Minnesota nursing home (NH) residents and the relationship between conventional or Alzheimer ’ s special care unit (SCU) placement and QOL. The study may inform development of dementia-specifi c quality measures. Design and Methods: Data for analyses came from face-to-face interviews with a representative sample of 13,130 Minnesota NH residents collected through the 2007 Minnesota NH Resident Quality of Life and Consumer Satisfaction survey. We examined 7 QOL domains: comfort, meaningful activities, privacy, environment, individuality, autonomy, relationships, and a positive mood scale. We applied multilevel models (resident and facility) to examine the relationship between the resident ’ s score on each QOL domain and the resident ’ s cognitive impairment (CI) level and SCU placement after controlling for covariates, such as activities of daily living dependency, pain, depression or psychiatric diagnosis, and length of stay. Results: Residents with more severe CI reported higher QOL in the domains of comfort and environment and lower QOL in activities, individuality, privacy and meaningful relationships, and the mood scale. Residents on SCU reported higher QOL in the meaningful activities, comfort, environment, and autonomy domains but had lower mood scores. Implications: Our fi ndings point to QOL domains that show signifi cant variation by CI and thus may be of greatest interest to consumers, providers, advocacy groups, and other stakeholders committed to improving dementia care. Findings are particularly applicable to the development of NH quality indicators that more accurately represent the QOL of NH residents with CI.
