No studies have compared care in the Department of Veterans Affairs (VA) with that delivered in commercial managed care organizations, nor have studies focused in depth on care comparisons for chronic, outpatient conditions.

Disparities clearly exist in the health care of racial and ethnic minorities. This position paper of the American College of Physicians (ACP) provides ample evidence illustrating that minorities do not always receive the same quality of health care, do not have the same access to health care, are less represented in the health professions, and have poorer overall health status than nonminorities. The ACP finds this to be a major problem in our nation's health system that must be addressed. The ACP is dedicated to working toward eliminating all disparities in health care. This position paper sets forth specific positions for reducing these disparities and will be the foundation for public policy advocacy by ACP for eliminating racial and ethnic disparities in health care.

Terminal sedation in patients nearing death is an important issue related to end-of-life care.

Cost pressures and changes in the health care environment pose ethical challenges and hard choices for patients, physicians, policymakers, and society. In 2000 and 2001, the American College of Physicians, with the Harvard Pilgrim Health Care Ethics Program, convened a working group of stakeholders--patients, physicians, and managed care representatives, along with medical ethicists--to develop a statement of ethics for managed care. The group explored the impact of a changing health care environment on patient-physician relationships and how to best apply the principles of professionalism in this environment. The statement that emerged offers guidance on preserving the patient-clinician relationship, patient rights and responsibilities, confidentiality and privacy, resource allocation and stewardship, the obligation of health plans to foster an ethical environment for the delivery of care, and the clinician's responsibility to individual patients, the community, and the public health, among other issues.

Slow adaptation of new information by providers may result in suboptimal care.

It has been hypothesized that certain Mycoplasma species may cause Gulf War veterans' illnesses (GWVIs), chronic diseases characterized by pain, fatigue, and cognitive symptoms, and that affected patients may benefit from doxycycline treatment.

In 1999, the American College of Physicians (ACP), then the American College of Physicians-American Society of Internal Medicine, and the American College of Cardiology/American Heart Association (ACC/AHA) developed joint guidelines on the management of patients with chronic stable angina. The ACC/AHA then published an updated guideline in 2002, which the ACP recognized as a scientifically valid review of the evidence and background paper. This ACP guideline summarizes the recommendations of the 2002 ACC/AHA updated guideline and underscores the recommendations most likely to be important to physicians seeing patients in the primary care setting. This guideline is the first of 2 that will provide guidance on the management of patients with chronic stable angina. This document will cover diagnosis and risk stratification for symptomatic patients who have not had an acute myocardial infarction or revascularization procedure in the previous 6 months. Sections addressing asymptomatic patients are also included. Asymptomatic refers to patients with known or suspected coronary disease based on history or on electrocardiographic evidence of previous myocardial infarction, coronary angiography, or abnormal results on noninvasive tests. A future guideline will cover pharmacologic therapy and follow-up.

Previous meta-analyses demonstrated that high-dose glucocorticoids were not beneficial in sepsis. Recently, lower-dose glucocorticoids have been studied.

Physicians, hospitals, and other health care facilities will assume the responsibility for aiding individuals injured by a terrorist act involving radioactive material. Scenarios have been developed for such acts that include a range of exposures resulting in few to many casualties. This consensus document was developed by the Strategic National Stockpile Radiation Working Group to provide a framework for physicians in internal medicine and the medical subspecialties to evaluate and manage large-scale radiation injuries. Individual radiation dose is assessed by determining the time to onset and severity of nausea and vomiting, decline in absolute lymphocyte count over several hours or days after exposure, and appearance of chromosome aberrations (including dicentrics and ring forms) in peripheral blood lymphocytes. Documentation of clinical signs and symptoms (affecting the hematopoietic, gastrointestinal, cerebrovascular, and cutaneous systems) over time is essential for triage of victims, selection of therapy, and assignment of prognosis. Recommendations based on radiation dose and physiologic response are made for treatment of the hematopoietic syndrome. Therapy includes treatment with hematopoietic cytokines; blood transfusion; and, in selected cases, stem-cell transplantation. Additional medical management based on the evolution of clinical signs and symptoms includes the use of antimicrobial agents (quinolones, antiviral therapy, and antifungal agents), antiemetic agents, and analgesic agents. Because of the strong psychological impact of a possible radiation exposure, psychosocial support will be required for those exposed, regardless of the dose, as well as for family and friends. Treatment of pregnant women must account for risk to the fetus. For terrorist or accidental events involving exposure to radioiodines, prophylaxis against malignant disease of the thyroid is also recommended, particularly for children and adolescents.

Negative results on simplified compression ultrasonography cannot rule out symptomatic deep venous thrombosis (DVT) without further testing, such as repeated ultrasonography several days later. Repeated testing is costly and inconvenient, and patients are sometimes less likely to return for follow-up tests.

The National Diabetes Prevention and Control Program has a dynamic and evolving scientific foundation. This article describes this program and how seminal research studies provide an impetus for its public health policy and programs. The charge and challenges of integrating science into past, current, and future program designs are detailed, as are the program's accomplishments. Areas requiring new science are explored, including better research to translate new findings into clinical and public health practice and models to evaluate the effect of public health on improved outcomes. The epidemic of diabetes and its increasing burden on public health demands a better understanding of existing science and its limitations and informed public dialogue and policy responses.

Facing limited resources and increases in demand from competing programs, policymakers and health care providers seek guidance from economic studies on how to use health care resources wisely. Previous economic studies mainly focused on estimating the cost of diabetes and cost-effectiveness of different interventions. These studies found that diabetes is costly and that its cost will continue to increase; thus, more resources should be devoted to research aimed at finding effective means to prevent the disease and its complications. In addition, the cost-effectiveness of interventions varies greatly in terms of quality-adjusted life-years gained; therefore, efficient uses of resources should be an important consideration when interventions are prioritized. The need for economic studies will continue to grow because of increasing demand for limited resources from the growing number of interventions available. Future studies should be of better quality and broadened in areas of research.

Eight studies included in a recent systematic review of the efficacy of diabetes self-management education were qualitatively reexamined to determine the presence of theoretical frameworks, methods used to ensure cultural appropriateness, and the quality of the instrument. Theoretical frameworks that help to explain complex pathways that produce health outcomes were lacking; culture indices were not incorporated into diabetes self-management education; and the instruments used to measure outcomes were inadequate. We provide recommendations to improve research on diabetes self-management education in community settings through use of a contextual framework that encourages targeting multiple levels of influence--individual, family, organizational, community, and policy.
