Multicenter Study
Missed diagnoses of acute myocardial infarction in the emergency department: results from a multicenter study.
To determine the rate of missed acute myocardial infarction (AMI) in the emergency department and the factors related to missed diagnoses. ⋯ The rate of missed AMI in the ED was only 1.9%. However, 25% of these might have been prevented had ST-elevation not been missed, and another 25% might have been prevented had patients who were recognized to have ischemic heart disease by the physician in the ED been admitted.

To assess the timing of key decisions and clinical events in the treatment of acute myocardial infarction with thrombolytic therapy. ⋯ Thrombolytics should be stocked and started in the ED. Emergency physicians should generally make the decision to administer thrombolytic therapy with reference to accepted protocols without awaiting an ED consultation from either private attendings or cardiologists.

Case Reports Multicenter Study Clinical Trial
Acute cardiac ischemia in patients with syncope: importance of the initial electrocardiogram.
To determine the prevalence of acute cardiac ischemia in emergency department (ED) syncope patients without chest pain and to determine which of these patients are at high risk for acute cardiac ischemia. ⋯ For syncope patients who have no chest pain or ischemic abnormality on the presenting ECG in the ED, acute ischemia appears to be unlikely. Admission to the cardiac care unit for these patients for possible myocardial ischemia is probably unnecessary. However, patients who have syncope and ischemic abnormalities on the ECG are at risk for acute cardiac ischemia, even in the absence of chest pain. Hospital admission to rule out myocardial infarction for these patients is prudent.

Multicenter Study Clinical Trial
Physician electrocardiogram reading in the emergency department--accuracy and effect on triage decisions: findings from a multicenter study.
To determine how well physicians in emergency departments read electrocardiographic (ECG) ST-segment and T-wave changes and how this affects triage decisions. ⋯ Physicians in emergency departments often misread the ST segments and T waves of patients with possible acute cardiac ischemia. Misreading is related to suboptimal triage and unnecessary CCU admission. Training emergency physicians to make these distinctions more accurately could improve medical care and hospital utilization.

Multicenter Study Comparative Study Clinical Trial
Use of emergency departments by elderly patients: projections from a multicenter data base.
To assess the use of emergency medical care by the elderly in the United States, including emergency department visits, level of ED care required, ambulance services, and hospital admission rate. ⋯ With the rapid growth of the size of the elderly population, it is important that we assess the emergency medical resources needed to care for the geriatric population.
