Delirium, or acute confusional state, which often results from hospital-related complications or inadequate hospital care for older patients, can serve as a marker of the quality of hospital care. By reviewing five pathways that can lead to a greater incidence of delirium--iatrogenesis, failure to recognize delirium in its early stages, attitudes toward the care of the elderly, the rapid pace and technological focus of health care, and the reduction in skilled nursing staff--we identify how future trends and cost-containment practices may exacerbate the problem. ⋯ Local strategies would include routine cognitive assessment and the creation of systems to enhance geriatric care, such as incentives to change practice patterns, geriatric expertise, case management, and clinical pathways. National strategies might include providing education for physicians and nurses to improve the recognition of delirium and the awareness of its clinical implications, improving quality monitoring systems for delirium, and creating environments to facilitate the provision of high-quality geriatric care.

Randomized Controlled Trial Clinical Trial
The effects of physical treatment on induced fever in humans.
Initial treatments for fever include the amelioration of underlying causes and administration of antipyretic medications. However, patients who fail these treatments are often actively cooled, which may be counterproductive because decreasing skin temperature increases the thermoregulatory core target temperature. Cooling may also provoke metabolic and autonomic stress and thermal discomfort. ⋯ We conclude that active cooling should be avoided in unsedated patients with moderate fever, because it does not reduce core temperature but does increase metabolic rate, activate the autonomic nervous system, and provoke thermal discomfort.

Although health-related quality of life in older people is generally assessed by measuring specific domains of health status, such as activities of daily living or pain, the association between health-status measures and patients' perceptions of their quality of life is not clear. Indeed, it is controversial whether these health-status measures should be considered measures of quality of life at all. Our objective was to determine the association between health-status measures and older patients' perceptions of their global quality of life. ⋯ On average, health status is a reasonable indicator of global quality of life for groups of older patients with recent illness. However, disagreement between patients' reported health status and their perceptions of their global quality of life was common. Therefore, assumptions about the overall quality of life of individual patients should not be based on measures of their health status alone.

Although a wide variety of recognized pathogens can cause community-acquired pneumonia, in many patients the etiology remains unknown after routine diagnostic workup. The aim of this study was to identify the causal agent in these patients by obtaining lung aspirates with transthoracic needle aspiration. ⋯ In our study, S. pneumoniae was the leading cause of community-acquired pneumonia, accounting for 25% of all cases, including about one-third of the cases the cause of which could not be ascertained with routine diagnostic methods.
