Comparative StudyClinical utility and validation of the Japanese version of Memorial Delirium Assessment Scale in a psychogeriatric inpatient setting.
Delirium is a common mental disorder in the elderly. The Memorial Delirium Assessment Scale (MDAS) was developed in 1997 to assess delirium severity over time. The purpose of the current prospective study is to assess the clinical utility, diagnostic potential, reliability and validity of the Japanese version of MDAS in a psychogeriatric unit setting. ⋯ High levels of consistency within raters (Cronbach's alpha=0.92) and reliability between raters (0.98) were indicated. The correlation between MDAS scores and rating on the Delirium Rating Scale (r=.74, P=.0011), the Clinician's Global Rating of delirium severity (r=.67, P=.0047), and the Mini Mental State Examination (r=-.54, P=.029) was fair. The MDAS seems to be a reliable measuring instrument for assessing delirium in elderly patients.

Evaluation of the Confusion Assessment Method (CAM) as a screening tool for delirium in the emergency room.
The objective of this study was to compare the results of the Confusion Assessment Method (CAM) obtained by a trained non-physician interviewer to those obtained by a geriatrician, among a sample of elderly patients seen in an emergency room. A group of 110 elderly patients (> or =66 years) were evaluated in the emergency room by a lay interviewer. The geriatrician conducted an interview in the presence of the lay interviewer. ⋯ In conclusion, the CAM used by a trained lay interviewer in the emergency room is sensitive, specific, reliable and easy to use for the identification of patients with delirium. The under-recognition and under-treatment of delirium is a major health issue and has important clinical and financial implications. The implementation of systematic screening in populations at risk could increase the rate of early detection and lead to the appropriate management of delirious patients.

Posttraumatic stress disorder (PTSD) is a prevalent disorder that adversely affects 2-5% of the general population. Little is known about PTSD in the primary care setting. The purpose of the present study was to evaluate the utility of a screening instrument for PTSD (the PCL-C) in primary care and to examine comorbidity, disability, and patterns of healthcare utilization among persons with PTSD in this setting. ⋯ Comorbidity with other mood and anxiety disorders is extensive. It remains to be seen if greater awareness and more aggressive treatment of PTSD in primary care will lead to improved functioning and reduced (or more appropriate) healthcare utilization. These are topics for further study.

Diagnosis of depression by primary care physicians versus a structured diagnostic interview. Understanding discordance.
In this paper, false-negative and false-positive cases of depressive illness are examined, differentiating levels of disagreement between a primary care physician's diagnosis and a standardized research diagnosis. Two stratified random samples of primary care patients in Seattle, USA (N = 373) and Groningen, The Netherlands (N = 340) were examined with the Composite International Diagnostic Interview-Primary Health Care Version (CIDI-PHC). Physician's severity ratings and diagnosis of psychological disorder were obtained. ⋯ The true false-negative patients were younger, more often employed, rated their own health more favorably, visited their doctor for a somatic complaint and made fewer visits than the underestimated, misdiagnosed, and concordant positive patients. Complete disagreement in depressive diagnoses between the primary care physician and research interview is not as frequent as indicated by an undifferentiated false-negative/ false-positive analysis. Differentiating levels of disagreement does more justice to diagnostic practice in primary care and provides guidance on how to improve the diagnostic accuracy of primary care physicians.
