Response to the ISAR-HP questions, baseline impairments and functional outcomes at three and twelve months in the three risk groups for functional decline.

ISAR-HP = identification of seniors at risk-hospitalized patients, IADL = instrumental activities of daily living, ADL = activities of daily living, SD = standard deviation.*Katz ADL index; range of scores between 0–6, with a higher score indicating more dependence.†Functional decline was measured with the Katz ADL index and the outcome at three or twelve months was compared to premorbid functioning two weeks prior to hospital admission. These data were only available for those patients still alive at follow up.
