New issues in geriatric care.

The rapid growth of the elderly population has increased the need for improved geriatric care and prevention of disability. For example, the prevalence and severity of osteoporosis can be reduced significantly by the use of estrogen, with or without added progestin, in postmenopausal women. A common and devastating problem of frail elderly persons is urinary incontinence, most cases of which can be classified without referral for urologic services. Appropriate treatment can improve nearly half of all cases of persistent incontinence. Comprehensive geriatric assessment is effective in guiding the treatment of frail elderly patients and leads to significantly improved outcomes under appropriate conditions. The advent of the teaching nursing home has shed light on the medical problems of elderly residents of nursing homes, including malnutrition, dysregulation of water and electrolyte balance, falling, cognitive and affective illnesses, behavior disturbances, infections, and pathogenic drug use. The future application of advanced technology may revolutionize nursing home care.
