Although 10% to 15% of patients admitted to acute care hospitals are in a state of delirium, few patients are given this diagnosis by their clinician. We field-tested the Diagnostic and Statistical Manual III (DSM-III) criteria for diagnosing delirium on 133 consecutively admitted patients to an acute medical ward. Twenty patients were delirious using DSM-III criteria, 19 more patients than were reported by the primary clinician. ⋯ Sixty-five percent of patients with delirium died, whereas significantly fewer (3.3%) of patients without delirium died (P less than .0001). We found that delirium could be readily and reliably detected (kappa coefficient of agreement = 0.62 for interrater reliability) using the DSM-III criteria. Clinicians should routinely screen hospitalized patients of all ages using DSM-III criteria to identify delirious patients for an immediate evaluation and treatment.

Comparative Study
Short Portable Mental Status Questionnaire as a screening test for dementia and delirium among the elderly.
Pfeiffer's Short Portable Mental Status Questionnaire (SPMSQ) is a brief screening test for organic brain syndromes. The validity of the SPMSQ was evaluated in a random sample of 119 community residents and 282 consecutively admitted medical inpatients. The SPMSQ proved to be a sensitive and specific screening test for moderate to severe dementia both in the community and hospital. ⋯ The validity of the SPMSQ was not as good for delirium because of its variable clinical picture. For screening purposes lower cut-off points than previously recommended should be used: three errors for dementia and two errors for delirium. Among Finnish elderly people it was not necessary to use correction for education in the SPMSQ.

Comparative Study
Old people in the emergency room: age-related differences in emergency department use and care.
Little is known about how the care received in emergency departments (ED) by the elderly population differs from that received by younger people. We prospectively abstracted ED records of 1620 consecutive patients visiting a large community hospital ED over a 22-day period in 1984 for demographic and medical variables. Charts of patients presenting with five specific complaints (dyspnea, chest pain, abdominal pain, syncope, and motor vehicle accidents) were also analyzed for process of care variables and, for patients hospitalized, the accuracy of the ED diagnosis. ⋯ Therapy for specific complaints showed less age effect. Although generally more diagnostic tests were performed on older patients, the ED diagnosis tended to be more accurate for younger patients. Our data indicate that the process of ED care may be substantially different for the elderly population and have implications for future planning and financing of medical care.

Although some researchers have suggested that the dexamethasone suppression test (DST) may be useful in differentiating between major depression and dementia in the elderly, recent reports of abnormal DST results in nondepressed, demented elderly have questioned the validity of the test in this population. This study compared the frequency of abnormal DST results in three groups of elderly inpatients: depressed/not demented; demented/not depressed; and depressed and demented. ⋯ In this sample, the DST was more likely to identify dementia than depression. Until further investigations clarify the parameters of DST use in the elderly, the diagnosis of depression and dementia should continue to be determined by sensitive interpretation of clinical findings, history, and other diagnostic tests.

Patients with temporal arteritis may be misdiagnosed because the headache does not affect the temples. The records of 24 patients with biopsy proven temporal arteritis were reviewed to determine the site and other qualities of headache. Past reports of the sites of headache in this disease were also reviewed. ⋯ Two patients had generalized headaches. The headache did not involve the temple in seven patients and two patients did not experience headaches. Temporal arteritis should be considered in every elderly individual who begins to complain of headache, no matter what the site, quality, severity, or time pattern.
