Assessing the new general competencies for resident education: a model from an emergency medicine program.

The Accreditation Council for Graduate Medical Education (ACGME) has promoted six areas that should be addressed during graduate medical training, or "general competencies" (GCs). According to the ACGME, these GCs should be reflected in the educational processes of all residency programs. In promulgating these competencies, however, the ACGME has not provided examples of core content, methods of implementation, or methods of evaluation. The authors propose a practical method for modifying an existing evaluation format, providing a template other programs could use in assessing residents' acquisition of the knowledge, skills, and attitudes reflected in the GCs.

QT dispersion may be a useful adjunct for detection of myocardial infarction in the chest pain center.

BACKGROUND: QT dispersion has been proposed as a noninvasive measurement of the degree of inhomogeneity in myocardial repolarization. Increased QT dispersion has been reported after myocardial infarction. We hypothesized that increased QT dispersion may be a useful adjunct for risk stratification in patients being evaluated in a chest pain center. METHODS AND RESULTS: Patients were admitted to the chest pain center for evaluation of chest pain. Exclusion criteria included (1) systolic blood pressure <90 mm Hg, (2) ischemia or infarction on the initial electrocardiograph (ECG), (3) elevated creatine kinase or MB fraction, and (4) chest pain associated with cocaine use. Serial creatine kinase and MB levels and ECGs were obtained at 0, 6, and 9 hours. Patients were monitored for (1) creatine kinase and MB rise, (2) ECG changes for infarction, (3) ST-segment changes, and (4) rest angina. A negative evaluation at the chest pain center led to an exercise stress test. Patients with a positive exercise stress test were admitted for further evaluation and patients with a negative exercise stress test result were discharged home. Patients were divided into 3 groups. Group 1 consisted of patients who were found to have an acute myocardial infarction (AMI), group 2 consisted of patients with prior history of coronary artery disease but no evidence of AMI, and group 3 consisted of patients without prior coronary artery disease or AMI. QT dispersion was measured on the initial ECG in all patients. A total of 586 patients were evaluated. Group 1 consisted of 13 patients with mean QT dispersion of 44.6+/-18.5 ms, group 2 consisted of 267 patients with a mean QT dispersion of 10.0+/-13.8 ms, and group 3 consisted of 303 patients with a mean QT dispersion of 10.5+/-10.0 ms. Analysis of variance showed a significantly higher QT dispersion in patients who had AMI compared with other patients with chest pain (P< .001). CONCLUSIONS: QT dispersion can be a useful diagnostic adjunct for detection of AMI in patients with chest pain with a normal ECG and normal cardiac enzymes.

Emergency management of acute myocardial infarction. Focus on pharmacologic therapy.

Treatment of acute myocardial infarction has evolved significantly in the past two decades. Reperfusion therapies of thrombolysis and percutaneous angioplasty are major advances that can be employed to save infarcting myocardium and reduce mortality. When reperfusion therapy is combined with the use of aspirin, beta-blockade, heparin, and nitroglycerin, the emergency management of the patient with myocardial infarction can be completed. Outcomes in patients are determined by what happens in the first few minutes to hours after onset, and any delay in diagnosis or treatment may have significant consequences. This article reviews intervention and treatment strategies for acute myocardial infarction.

Evaluation of syncope in the emergency department.

Although most cases of syncope are benign, an adequate evaluation, which begins in the emergency department, is required to exclude life-threatening disorders. In addition, life-threatening disorders such as QT prolongation as well as confounding alternative diagnoses (e.g., seizure disorder) are also discussed.

Dual approval of a residency program: ten years' experience and implications for postdoctoral training.

In 1985, the American Osteopathic Association (AOA) changed its educational policies to permit osteopathic postdoctoral programs in settings that were accredited by the Accreditation Council for Graduate Medical Education (ACGME). In response to this policy change, an existing ACGME-accredited emergency medicine residency was modified to create a combined osteopathic/allopathic residency program that meets the educational requirements of both the AOA and the ACGME. Our 10-year experience with this combined osteopathic/allopathic emergency medicine residency is described in terms of program development, governance structure involving key stakeholders, faculty distribution--equal numbers of allopathic and osteopathic faculty, and educational outcome of the total number of residents graduated (93 graduates, with 33 osteopathic physicians and 60 allopathic physicians). Lessons learned from the 10 years' experience of this combined residency program, as well as current issues, are explained. The future potential of such dual-approved programs on the supply of residency positions is discussed from the viewpoint of osteopathic postdoctoral education.

Clinical practice guidelines: a review.

The development of clinical practice guidelines has spread from utilization review agencies to physician specialty societies, federal agencies, managed care organizations, and academic health centers as their usefulness in accomplishing the goals of healthcare reform become clear. The author reviews the mounting evidence that variation in the practice of medicine suggests that patients in some areas are not receiving all needed services, while others are receiving unnecessary services. He explores the implications of practice guidelines for improving the quality of care while controlling cost. Practice guidelines are defined and distinguished from medical review criteria. The author explores the challenges in governance, funding, and guideline development and communication that will have to be overcome to establish the credibility of practice guidelines. Finally, he addresses the opportunities for the osteopathic medical profession to establish its uniqueness in this setting.

'Blueprint' for creating classroom facilities in teaching hospitals.

Classroom facilities in teaching hospitals have evolved from simple rooms with blackboards to sophisticated amphitheaters with high-tech audiovisual equipment. This article presents a "blueprint," which was used in an osteopathic hospital, to renovate existing space into classrooms that are conducive to learning.

Traumatic rupture of right mainstem bronchus in a child.

We report a case of a 7-year-old boy who sustained a ruptured right mainstem bronchus in a motor vehicle accident. The clinical presentation, pathophysiology, and diagnosis of tracheobronchial injuries secondary to nonpenetrating thoracic trauma are discussed.

Adenosine-induced ventricular fibrillation.

The use of adenosine has been suggested as a diagnostic tool in the evaluation of wide ORS complex tachycardia. However, adenosine shortens the antegrade refractoriness of accessory atrioventricular connections and may cause acceleration of the ventricular rate during atrial fibrillation. We observed ventricular fibrillation in 2 patients who presented to the emergency department with pre-excited atrial fibrillation and were given 12 mg of adenosine.
