We randomly assigned frail elderly inpatients with a high probability of nursing-home placement to an innovative geriatric evaluation unit intended to provide improved diagnostic assessment, therapy, rehabilitation, and placement. Patients randomly assigned to the experimental (n = 63) and control (n = 60) groups were equivalent at entry. At one year, patients who had been assigned to the geriatric unit had much lower mortality than controls (23.8 vs. 48.3 per cent, P less than 0.005) and were less likely to have initially been discharged to a nursing home (12.7 vs. 30.0 per cent, P less than 0.05) or to have spent any time in nursing home during the follow-up period (26.9 vs. 46.7 per cent, P less than 0.05). The control-group patients had substantially more acute-care hospital days, nursing-home days, and acute-care hospital readmissions. Patients in the geriatric unit were significantly more likely to have improvement in functional status and morale than controls (P less than 0.05). Direct costs for institutional care were lower for the experimental group, especially after adjustment for survival. We conclude that geriatric evaluation units can provide substantial benefits at minimal cost for appropriate groups of elderly patients, over and above the benefits of traditional hospital approaches.

This article presents results of a prospective multivariate study of hospitalized elderly patients at an acute-care Veterans Administration (VA) hospital to identify factors on hospital admission predictive of several short- and long-term outcomes: in-hospital and 6-month mortality, immediate and delayed nursing home admission, length of hospital stay, and 6-month rehospitalization. All patients aged 70 years and over admitted to acute-care beds on the medical service wards during a 1-year period were included in the study (N = 396). Factors most predictive of 6-month mortality (using logistic regression) were decreased functional status, admitting diagnosis, and decreased mental status. Factors most predictive of nursing home admission were decreased functional status, living location, and decreased mental status. Functional status was a stronger predictor of length of stay, mortality, and nursing home placement than was principal admitting diagnosis--of relevance to the current emphasis on diagnosis-related groups (DRGs). These data may be helpful in improving discharge planning, in resource allocation, and in targeting patients for different specialized geriatric programs.

Measuring functional status using specific instruments is an important part of geriatric assessment. These instruments, however, often rely on data sources different from those with which they were originally validated. To study possible biasing effects of different data sources on functional status scores, we examined scores for two widely used instruments (the Lawton Personal Self-Maintenance Scale, PSMS, and Instrumental Activities of Daily Living, IADL, Scale) on a group of hospitalized elderly (n = 61) using three different data sources (the patients themselves, the patients' nurses, and significant others). Analysis showed that PSMS scores derived from patients were significantly higher than scores derived from significant others (p less than .025) and that patient-derived IADL scores were significantly higher than both nurse-derived scores (p less than .001) and significant-other-derived scores (p less than .001). We also compared scores for a group of nursing home patients (n = 68) on the Katz Activities of Daily Living (ADL) Scale, using data obtained from patients and their nurses. Again, the patient-derived scores were significantly higher than those from nurses (p less than .001). We conclude that data sources for determining patient functional ability are not interchangeable and that patients may overstate their functional abilities, whereas significant others may understate them, relative to judgments of skilled nursing personnel.
