Although health-related quality of life in older people is generally assessed by measuring specific domains of health status, such as activities of daily living or pain, the association between health-status measures and patients'perceptions of their quality of life is not clear.
Indeed, it is controversial whether these health-status measures should be considered measures ofquality oflife at all.
Our objective was to determine the association between health-status measures and older patients'perceptions of their global quality of life.
We performed a cross-sectional study of 493 cognitively intact patients 80 years of age and older, interviewed 2 months after a hospitalization.
We measured patients'self-assessed global quality of life and four domains of health status : physical capacity, limitations in performing activities of daily living, psychological distress, and pain.
Each of the four scales was significantly correlated with patients'global perceptions of their quality of life (P<0.001).
The ability of the health-status scales to discriminate between patients with differing global quality of life was generally good, especially for the physical capacity (c statistic=0.72) and psychological distress scales (c statistic=0.70).
However, for a substantial minority of patients, scores on the health-status scales did not accurately reflect their global quality of life. (...)
