Racial disparities in diagnosis and treatment of depression: a literature review.

The purpose of this study was to systematically review the literature to determine whether racial disparities exist in the diagnosis and treatment of depression in the United States. A literature search using PubMed of potentially relevant articles in English that include data from population-based studies examining the diagnosis and/or treatment of depression; or data from prospective studies stratifying the rates of diagnosis and/or treatment of depression by race/ethnicity and ethnic comparisons between Caucasians, African Americans and/or Hispanics. Initial searches identified 2,396 articles. On the basis of our criteria, 14 articles were eligible for inclusion in this review. Four included data on the diagnosis of depression in different ethnic groups; their results were not consistent. Twelve included data on treatment variability in the treatment of depression; overall these suggested lower rates of treatment for African Americans and Hispanics than for Caucasians. More research is needed focusing on ethnic variation in the diagnosis of depression. Racial disparities exist in the treatment of depression.

Prevalence of dementia among Veterans Affairs medical care system users.

OBJECTIVES: In an aging population, the number of veterans diagnosed with dementia is likely to increase. Knowledge of existing dementia prevalence will be beneficial in planning for future patient care needs. Our objectives were to assess the prevalence of the dementia diagnosis among those treated at Veterans Affairs (VA) medical centers and determine how it varies across race and Veterans Integrated Service Network (VISN). MATERIALS AND METHODS: Data were collected on all veterans seen within the VA medical system from 1997 through the first half of 2001. Only veterans aged 65 and over were included in the study. Veterans were included if they had one of the following dementia ICD-9 codes: 290.XX, 291.2, 294.XX, 331.XX, 046.1, or 046.3. RESULTS: The overall prevalence of dementia was 7.3%. The prevalence of dementia was similar among white patients and patients of other races, except African-American patients, in whom it was 50% higher. Across VISNs, the prevalence of dementia ranged from 5.8 to 9.4%. Alzheimer's disease was the most frequently diagnosed type of dementia within the VA, and inpatient service utilization and outpatient psychiatry visits by individuals with dementia were high relative to other VA patients. DISCUSSION: The overall prevalence identified is consistent with that reported in the literature, as is the elevated prevalence in African-Americans versus whites. The data on prevalence by VISN may identify regional variation in either the types of dementia present or the diagnostic criteria used. The dementia diagnosis is clearly associated with substantial service use.

Evidence-based rheumatology practice.

PURPOSE OF REVIEW: This review is intended to update readers on recent developments in the evidence-based practice of rheumatology. RECENT FINDINGS: Several new or updated evidence-based practice guidelines have recently emerged. In addition, a large body of evidence upon which to base practice has been addressed in the many systematic reviews and meta-analyses that have been newly published, including nine new or updated Cochrane reviews. Several studies have also investigated adherence to practice guidelines, interventions to improve clinical practice, and quality of care in the field of rheumatology in the past year. SUMMARY: Evidence-based rheumatology is an ongoing effort, with continuing revision and update of recommendations. It may currently be used to address a wide variety of clinical questions. The initiatives on practice-based research to establish quality indicators and identify areas where rheumatology practice can be enhanced are a welcome addition to health services research in this field.

A practical screening tool for anxiety and depression in patients with chronic breathing disorders.

Obstructive lung diseases are associated with high rates of depression and anxiety, yet many patients are never screened or treated. This study evaluated the five-question Depression and Anxiety modules of the Primary Care Evaluation of Mental Disorders (PRIME-MD) Patient Questionnaire as a telephone screen in 1,632 patients with chronic breathing disorders at a Veterans Affairs Medical Center in Houston, TX. Subsequent testing of 828 patients with the Beck Depression Inventory-II and the Beck Anxiety Inventory showed that the sensitivity and specificity, respectively, of the Depression and Anxiety modules of the PRIME-MD Patient Questionnaire screening were 94.6% and 49.5% (Depression); 93.7% and 32.2% (Anxiety); and 97.7%, and 36.0% (combined screen), with an overall accuracy of 80.7%. In such populations, these two modules of the PRIME-MD Patient Questionnaire may be a useful screening tool.
