This prospective, cohort study analyzed the prevalence of alcoholism and patterns of alcohol intake over time in a cohort of HIV-infected patients, predominantly homosexual/bisexual men. One hundred eleven HIV-positive subjects were recruited from a comprehensive HIV clinic associated with a large Midwestern university hospital. Each participant completed the Michigan Alcoholism Screening Test (MAST) survey and a standardized quantity-frequency questionnaire on alcohol intake at enrollment. The quantity-frequency scale was repeated every six months for a total of 30 months. Forty-five of the 111 subjects (41%) met the criteria for alcoholism, as defined by a MAST score 5 or higher. There was a significant decrease in alcohol consumption over time, from 6.4 drinks/week in the initial time period to 3.9 drinks/week by the final time period (p < 0.001).
Objective: 1 ) To examine the ordering of head CT scans in elder patients with delirium and cognitive impairment; and 2) to report CT scan findings associated with these conditions. Methods: This was a 2-part study. Part 1 was a prospective, observational study of 560 adults >70 years of age evaluated at 3 separate EDs using a 200-hour stratified sampling process at each ED. During Part 1, the frequencies of specific findings (i.e., delirium, impaired consciousness, and impaired cognition) and CT scan rates for these groups were determined. Part 2 was a retrospective analysis of CT scan reports and medical records ( n = 279) for patients >70 years of age i n the prospective sample (11 = 79) and from a sample ( n = 200) of CT scans obtained at a fourth ED. Part 2 examined clinical findings detected in the ED to determine those factors that were associated with acute findings on CT scan. Results: Part 1: There were 333 (59.4%) patients prospectively classified as having impaired cognition, irnpaired consciousness, or delirium; 79 (23.7%) of these patients had a head CT scan. Of these 3 groups, delirious patients were more frequently scanned ( p < 0.001). Part 2: Of 279 C T scans, 42 (15.0%) were positive for an acute condition (hemorrhage, hematoma, space-occupying lesion, infarct). Of 42 positive scans, 40 (95.1%) were found in the 102 (36.6%) patients with either impaired consciousness or a new focal neurologic finding detected in the ED. Conclusions: Considerable variability in ED CT scan ordering exists for elder patients with neurologic findings. Impaired consciousness and/or new focal neurologic signs are associated with acute findings on CT scan in elder patients. Acute CT abnormalities are uncommon in elder ED patients with other neurologic findings. Additional prospective evaluation is warranted prior to guideline development for CT scans in this patient population. Key words: CT scans; delirium; elders; emergency department. 13,703.

Presently there are few data to guide the selective ordering of head CT scans for delirious patients.' Improved efficiency in the use of CT scanning could shorten length of stay in the ED, reduce costs, and, if clinical findings prove to be valuable for triage, promote an individualized approach to the tare of cognitively-impaired elder adults. Our previous work outlines some of the challenges for assessing cognitively-intact vs cognitively-impaired elder adult^.^ As background f o r guideline development for the evaluation and management of cognitive impairment, es-

When controlled for important predictors of expected resource use, care provided by a geriatric management team resulted in a significant reduction in the cost of hospitalization. A reduction in the cost of laboratory, cardiographic, and pharmacy services is consistent with the team's philosophy of defining the services needed based on goals related to functional outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
