The physician's role in minimizing prehospital delay in patients at high risk for acute myocardial infarction: recommendations from the National Heart Attack Alert Program. Working Group on Educational Strategies To Prevent Prehospital Delay in Patients at High Risk for Acute Myocardial Infarction.

Physicians and other health care professionals play an important role in reducing the delay to treatment in patients who have an evolving acute myocardial infarction. A multidisciplinary working group has been convened by the National Heart Attack Alert Program (which is coordinated by the National Heart, Lung, and Blood Institute of the National Institutes of Health) to address this concern. The working group's recommendations target specific groups of patients: those who are known to have coronary heart disease, atherosclerotic disease of the aorta or peripheral arteries, or cerebrovascular disease. The risk for acute myocardial infarction or death in such patients is five to seven times greater than that in the general population. The working group recommends that these high-risk patients be clearly informed about symptoms that they might have during a coronary occlusion, steps that they should take, the importance of contacting emergency medical services, the need to report to an appropriate facility quickly, treatment options that are available if they present early, and rewards of early treatment in terms of improved quality of life. These instructions should be reviewed frequently and reinforced with appropriate written material, and patients should be encouraged to have a plan and to rehearse it periodically. Because of the important role of the bystander in increasing or decreasing delay to treatment, family members and significant others should be included in all instruction. Finally, physicians' offices and clinics should devise systems to quickly assess patients who telephone or present with symptoms of a possible acute myocardial infarction.

The development and evaluation of new versions of the written examination for the American Heart Association Advanced Cardiac Life Support provider course.

STUDY OBJECTIVE: To create new versions of the written, multiple-choice examination used in the American Heart Association (AHA) Advanced Cardiac Life Support course, evaluate their reliability and difficulty, and then design revised versions with improved reliability and of standardized difficulty. DESIGN: Psychometric evaluation of new versions of the AHA Advanced Cardiac Life Support test and revisions. SETTING: AHA Advanced Cardiac Life Support courses. PARTICIPANTS: Candidates for completion of AHA Advanced Cardiac Life Support provider courses in five states. INTERVENTION: The course content was divided into 11 content areas that were weighted for importance and appropriateness for testing in a multiple-choice format. The weights were used to construct a blueprint for a 50-question, multiple-choice examination. Five versions of the examination were then constructed based on the content blueprint, drawing from new questions and expert revision of previously written questions. Reliability and difficulty were assessed using 915 administrations at five different sites nationwide. The initial test versions differed in their degree of difficulty, which was not explained by demographic factors. The results were used to revise three of the versions to improve reliability and equalize difficulty of the versions. MEASUREMENTS AND MAIN RESULTS: The final five versions have estimated reliability ranging from Cronbach's alpha of .62 to .86. Mean scores ranged from 87.4% to 89.1%. CONCLUSION: After field testing and revision, five examinations with acceptable reliability and roughly equal difficulty were constructed. The new examinations test the participants' knowledge of important aspects of resuscitation science and practice based on a blueprint of the course content.

[Disseminated Kaposi's sarcoma of the skin in a young homosexual with substance abuse].

This is a report on a young homosexual US citizen with disseminated Kaposi's sarcoma of the skin who has lived in Berlin for about 1 year. During the last few years this malignant variant of the conventional Kaposi's sarcoma-characterized by rapid generalization and aggressive course--has become epidemic in some big cities in the USA. Until now there exist only a few reports from Europe. The data of our patient are representative of the typical epidemiologic, anamnestic, clinical, and diagnostic features of this unusual disease. Acquired immunodeficiency, high frequency of infections, and drug abuse may represent major etiologic factors. This report underlines the possibility that the disseminated type of Kaposi's sarcoma in young men may be observed more often in Europe in the near future.
