Randomized Controlled Trial Clinical Trial
Computerized decision support based on a clinical practice guideline improves compliance with care standards.
Clinical guidelines are designed to assist in the management of specific diseases; however, these guidelines are often neglected in the delivery of care. The purpose of this study was to determine whether clinician use of an clinical practice guideline would increase in response to having, at the patient visit, a decision support system based on a practice guideline that generates a customized management protocol for the individual patient using data from the patient's electronic medical record. ⋯ Decision support based on a clinical practice guideline is an effective tool for assisting clinicians in the management of diabetic patients. This decision support system provides a model for how a clinical practice guideline can be integrated into the care process by computer to assist clinicians in managing a specific disease through helping them comply with care standards. Use of decision support systems based on clinical practice guidelines could ultimately improve the quality of medical care.

Multicenter Study
Gender, quality of life, and mental disorders in primary care: results from the PRIME-MD 1000 study.
Recently there has been increased interest in the special mental health needs of women. We used data from the PRIME-MD 1000 study to assess gender differences in the frequency of mental disorders in primary care settings, and to explore the potential impact of these differences on health-related quality of life (HRQL). ⋯ In the 1,000 patients of the PRIME-MD study, mood, anxiety, and somatoform disorders and psychiatric comorbidity were all significantly more common in women than men. The HRQL scores were poorer in women than men, although most of this difference was accounted for by the difference in prevalence of mental disorders. These data suggest that one of the most important aspects of a primary care physician's care of female patients is to screen for and treat common mental disorders.

To determine the sites of thromboses (venous versus arterial circulation) that complicate the clinical course of immunemediated heparin-induced thrombocytopenia, and to determine the 30-day risk for thrombosis in patients who are initially recognized with isolated heparin-induced thrombocytopenia. ⋯ Venous thrombosis complicates heparin-induced thrombocytopenia more frequently than does arterial thrombosis. The high risk of thrombosis in patients initially recognized with isolated thrombocytopenia suggests that conventional management approaches require reappraisal.

In patients with coronary artery disease (CAD), left ventricular (LV) function, the number of diseased vessels, and the severity of myocardial ischemia are important determinants of survival. These factors can be used to identify subsets of high-risk patients who are candidates for aggressive intervention. Among patients with LV dysfunction, those with left main CAD, three-vessel disease, and one- or two-vessel disease with inducible ischemia are at highest risk. ⋯ The risk in this population is exacerbated by the abnormalities in lipid metabolism associated with the diabetic state. CAD mortality increases with aging, but it is recommended that elderly patients with CAD also receive risk factor intervention, such as cholesterol-lowering therapy. Consideration of the impact of such therapy on quality of life is especially important in initiating such interventions in the older population.

Chronic fatigue syndrome (CFS) is a condition that may be associated with substantial disability. The Medical Outcomes Study Short-Form General Health Survey (SF-36) is an instrument that has been widely used in outpatient populations to determine functional status. Our objectives were to describe the usefulness of the SF-36 in CFS patients and to determine if subscale scores could distinguish patients with CFS from subjects with unexplained chronic fatigue (CF), major depression (MD), or acute infectious mononucleosis (AIM), and from healthy control subjects (HC). An additional goal was to ascertain if subscale scores correlated with the signs and symptoms of CFS or the presence of psychiatric disorders and fibromyalgia. ⋯ The SF-36 is useful in assessing functional status in patients with fatiguing illnesses. Patients with CFS and CF have marked impairment of their functional status. The severity and pattern of impairment as documented by the SF-36 distinguishes patients with CFS and CF from those with MD and AIM, and from HC, but does not discriminate between CF and CFS.
