A total of 221 elderly patients between the ages of 70 to 99 years who presented to a community-based teaching hospital emergency room were prospectively evaluated by assessing for fever (greater than or equal to 37.5 degrees C), leukocytosis (greater than or equal to 14,000/mm3) and bandemia (greater than 6%) as a screening method for predicting the presence of bacterial infection. Thirty-three patients had documented bacterial infections. Although with increasing body temperature the percent of patients who were infected increased, 48% of the infected elderly patients had no fever. ⋯ In patients with fever, leukocytosis, and bandemia, all patients were infected. Conversely, in the absence of fever, leukocytosis, and bandemia, only 6% had bacterial infection. All elderly patients who present with an acute or subacute change in health status or functional capabilities associated with fever, leukocytosis, or bandemia should be carefully assessed for the high probability of a bacterial infection.

During implementation of a new Do-Not-Resuscitate (DNR) policy in New York State, decisions by 233 nursing home patients of their surrogates were evaluated. Eighteen patients with capacity (mean age +/- SD = 76.4 +/- 12.1 years) chose DNR; 30 patients with capacity (mean age +/- SD = 76.2 +/- 10.7 years) chose to be resuscitated (CODE); 54 patients without capacity, (mean age +/- SD = 86.1 +/- 9.1 years) had surrogates who chose DNR; and 131 patients without capacity and with surrogates (mean age +/- SD = 81.9 +/- 9.8 years) remained CODE. Most patients with capacity who chose DNR had multiple sclerosis, while most choosing CODE had strokes. ⋯ Forty-five percent of surrogates did not respond regarding CODE status during the three-month study interval, and 10% wanted additional time to decide. Patient age appeared to be a factor in surrogate choice for DNR but not in patients with capacity making their own decision. Reasons for patients with capacity choosing DNR are discussed; perceived quality of life and premorbid feelings by patients help in the decision-making process.

This study examined the prescribing of psychotropic drugs for patients 65 years of age and older in nursing homes using data from the 1984 National Nursing Home Survey pretest. The most frequently used antipsychotic, anxiolytic, antidepressant, and sedative/hypnotic medications were respectively: haloperidol, hydroxyzine, doxepin, and temazepam. ⋯ More than one-fourth of the study patients had orders for more than one psychotropic medication. Nursing home patients who received psychotropics had concurrent orders for an average of 3.3 nonpsychotropic medications, many of which could increase the possibility of drug interactions and potential side effects.

The acute confusional state (delirium) is a common presentation for a wide variety of medical conditions in the elderly. This paper reports a prospective study of acute confusion in elderly people admitted to general medical services in two acute care hospitals in Edmonton, Alberta. Eighty patients were studied, ranging in age from 65-91. ⋯ Confusion was a sensitive sign of physical illness, and its resolution accompanied recovery. A diagnosis of the cause of the confusion state could be made in 22 of 24 cases. These findings support the aggressive investigation and treatment of acute confusion in the elderly.

We analyzed factors associated with the discharge diagnosis of delirium among 1,285 patients admitted to a major teaching hospital during a 2-year period, developed a model to classify the risk of developing delirium on the basis of clinical and diagnostic data, and tested the model on 471 patients admitted during the subsequent year. Using the multivariate technique of recursive partitioning, we identified four factors that distinguished 80% of all cases of delirium: 1) a urinary tract infection at any time during the hospital stay (odds ratio = 3.1; 95% confidence interval = 2.02-4.58); 2) no urinary tract infection, but low serum albumin on admission (odds ratio = 2.4; 95% confidence interval = 1.43-3.99); 3) neither urinary tract infection nor low serum albumin, but elevated white blood cell count on admission (odds ratio = 1.99; 95% confidence interval = 1.18-3.37); 4) none of these risk factors, but proteinuria on admission (odds ratio = 1.82; 95% confidence interval = 1.25-2.66). ⋯ Among individuals with delirium, in-hospital mortality and hospital charges were higher. The model developed accurately characterized the risk of delirium when it was tested on patients admitted to the same hospital during the subsequent year.
