Clinical Trial Controlled Clinical Trial
Controlled trial of a geriatric case-finding and liaison service in an emergency department.
To evaluate the effects of a program of case-finding and liaison service for older patients visiting the emergency department. ⋯ Numerous previously unrecognized geriatric medical and social problems can be detected in older persons visiting the emergency department. Despite this, an emergency department-based geriatric assessment and management program failed to produce improved outcomes. This suggests that either disease acuity is an overwhelming factor in subsequent outcome or, alternatively, more control over medical and social service delivery during and after the emergency department visit than was demonstrated in this program will be required before successful outcomes can be assured.

Many practitioners perform a thyroid stimulating hormone (TSH) assay as a screening test in older patients. The introduction of sensitive TSH assays with lower normal limits has created a laboratory abnormality that is often of uncertain significance. Mechanisms include autonomous overproduction of thyroid hormone, nonthyroidal illness including medication effects, and hypothalamic/pituitary dysfunction. ⋯ Low total T3 levels, TSH normalization, and excess mortality suggest that nonthyroidal illness plays a role in the pathogenesis of low TSH determinants in the nursing home. Autonomous production of thyroid hormone also plays a role. We believe that the term "subclinical hyperthyroidism" should be used only if the clinician believes that autonomous overproduction of thyroid hormone is the cause of a low TSH level. If subsequent research shows correctable adverse consequences associated with subclinical hyperthyroidism from autonomous overproduction of thyroid hormone, a more aggressive diagnostic approach will be needed to define the mechanism of a low TSH level at the time of its discovery.

To assess patients' willingness to accept life-sustaining treatment when the expected outcome is a diminished mental health state. ⋯ In the case of "severe pneumonia", about half of our older male veterans reported a willingness to accept intubation and ventilatory support even if it resulted in persistent cognitive disability. These results suggest that experience in a medical intensive care unit with the ventilators and experience with strokes may make patients more tolerant of treatments that may result in impaired cognitive function.
