Health-related quality of life (HRQOL) levels and their determinants in those living in nursing homes are unclear. The aim of this study was to investigate different HRQOL domains as a function of the degree of cognitive impairment and to explore associations between them and possible determinants of HRQOL.
Five HRQOL domains using the Minimum Data Set - Health Status Index (MDS-HSI) were investigated in a large sample of nursing home residents depending on cognitive performance levels derived from the Cognitive Performance Scale. Large effect size associations between clinical variables and the different HRQOL domains were looked for.
HRQOL domains are impaired to variable degrees but with similar profiles depending on the cognitive performance level. Basic activities of daily living are a major factor associated with some but not all HRQOL domains and vary little with the degree of cognitive impairment.
This study is limited by the general difficulties related to measuring HRQOL in patients with cognitive impairment and the reduced number of variables considered among those potentially influencing HRQOL.
HRQOL dimensions are not all linearly associated with increasing cognitive impairment in NH patients. Longitudinal studies are required to determine how the different HRQOL domains evolve over time in NH residents.
