| Annotation | Indicators of physical function and health status can predict important outcomes in older people, but little is known about the meaning of change in these measures. This study assesses the magnitude and patterns of change occurring in 1 year in six measures of health and function, and simulated the effect on survival for 5 years. This prospective cohort study was based in two US health care systems. Data were collected during home visits at baseline and every 3 months for one year. Subsequent deaths occurring within 5 years were ascertained using the National Death Index. Of 439 older people, 88 (20%) died within the subsequent 5 years. The optimal magnitude of decline to predict 5-year mortality was 0.1 metres per second gait speed, 1 point in the Short Physical Performance Battery, and 0.05 points for Euroqol. Independent contributions were found for decline in gait speed, Short Physical Performance Battery, global health, and activities of daily living (ADLs). More than half of the episodes of decline were transient. Persistent decline at 1 year consistently predicted death, and transient decline in gait speed and global health increased mortality risk compared with no change. (RH). |
