Improved survival for frail elderly inpatients on a geriatric evaluation unit (GEU): who benefits?

Previously reported data from a randomized controlled trial showed that admission to the geriatric evaluation unit (GEU) and follow-up clinic at the Sepulveda VA Medical Center leads to significantly improved outcomes for frail elderly hospital patients--including a 50% reduction of one-year mortality (p less than 0.005). In the present paper, two-year survival curves for GEU and control groups are reported. In addition, we subdivided the population by potential baseline risk factors (both patient- and treatment-related) and examined one-year survival using 12-month survival curves and odds ratios. There is evidence for GEU-related survival effects in specific subgroups of patients (e.g. patients with heart and pulmonary disease, patients with low baseline scores in functional status and mental status, and patients with high baseline morale scores). Finally, employing stepwise logistic regression, we determined the predictors of one-year survival in the pooled study population. These factors were: assignment to the GEU (adjusted odds ratio = 2.45; p less than 0.001); not having a heart diagnosis (2.24; p less than 0.001); and having primarily "geriatric/rehabilitation" problems (1.95; p less than 0.005). A predictive model derived from the regression defines patient subgroups likely to survive only when assigned to the GEU: cardiac patients with primarily "geriatric" or "rehabilitation" problems, and non-cardiac patients whose problems are primarily "medical". The dramatic effect of the GEU on survival appears to be concentrated on certain identifiable subgroups of patients who might be targeted to maximize program cost-effectiveness.

Predictors of immediate and 6-month outcomes in hospitalized elderly patients. The importance of functional status.

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.

Geriatric assessment on a subacute hospital ward.

The authors collected data on all patients admitted to the Sepulveda Veterans Administration Geriatric Evaluation Unit (GEU) during its first 6 years of operation. Analysis of these data indicate several beneficial effects associated with this type of specialized geriatric care: improved diagnostic accuracy, reduced use of drugs, improved functional status, and improved placement location. The authors also analyzed additional data from a previously published, randomized controlled trial to compare better process of care between patients randomized to the GEU and those receiving usual services. During their initial hospitalizations, GEU patients received significantly more specialty evaluations than controls (4.9 versus 1.7, p less than .001), had longer lengths of stay (85.1 days versus 44.3 days, p less than .001), had more new diagnoses discovered (2.9 versus 0.6, p less than .001), and had more drugs discontinued from their regimens (4.6 versus 2.3 p less than .001). These process differences were probably related to the previously reported outcome differences: GEU patients were more likely than controls to show improvements in functional status, affect, placement location, use of institutional services, and survival.

The development of health and social services for the elderly in Iceland: an overview.

In the present paper, we provide a general overview of the changing position of the aged population in Iceland. After a long history of subsistence, Icelandic society has evolved only recently from pre-industrial conditions compared with other Western developed nations. The 1000-year preindustrial record is in large part one of a struggle for survival in which formal and informal measures to support the frail and disabled were often overwhelmed by disease and famine; this history is outlined to provide a baseline for recent changes. Both the speed and propinquity of Iceland's transition from these conditions have left a unique stamp on the present-day society: development has driven a quick elaboration of occupational roles and other social status shifts, vast health status improvements, and great population and urban growth. Public and personal health services have grown in scope and adequacy in comparatively recent decades, contributing to the now unsurpassed health status of the general population. The effect of these trends on the condition of elderly is described. As the birth rate in Iceland has dropped in recent decades, the proportion and number of Icelanders in the older and especially the oldest age-strata has been steadily rising. The current and planned organization of health and social services is reviewed, as Iceland faces new tasks of caring for elderly.

Differential prognosis and utilization patterns among clinical subgroups of hospitalized geriatric patients.

While screening elderly inpatients on acute Veterans Administration (VA) hospital wards for a special geriatric program, we prospectively classified all patients age 65 and over, who had been hospitalized at least a week, into five clinical subgroups using specific diagnostic, prognostic, and functional criteria. These five subgroups were "geriatric evaluation unit (GEU) candidate", "severely demented", "medical", "terminal", and "independent". Medical record data from the initial admission and a full year of follow-up were collected from random samples of each subgroup and of nonscreened patients who had been hospitalized for less than a week. Analysis revealed that each subgroup had a distinctive pattern of survival, living location, and use of institutional services during the follow-up period. For one major subgroup ("GEU candidate"), a specific intervention (the GEU) has proved very effective in reducing mortality, increasing patient functioning, improving placement, and decreasing use of institutional services. Moreover, there are specific treatment and intervention strategies appropriate for each of the other subgroups (e.g., hospital-based home care, hospice, respite, and day treatment programs), although these services are not universally available nor clearly proved effective. The process of identifying patient subgroups illustrated in this study may be useful in needs assessment, in planning new intervention programs for frail elderly patients, and for identifying appropriate patients for these programs.
