Multicenter Study
Faculty evaluation by residents in an emergency medicine program: a new evaluation instrument.
Evaluation of preceptors in training programs is essential; however, little research has been performed in the setting of the emergency department (ED). The goal of this pilot study was to determine the validity and reliability of a faculty evaluation instrument-the Emergency Rotation (ER) scale-developed specifically for use in emergency medicine (EM). ⋯ The ER scale appears to be valid and reliable. It performs well when compared with previously psychometrically tested tools. It is a sensible, well-adapted tool for the teaching environment offered by EM.

Randomized Controlled Trial Multicenter Study Clinical Trial
Impact of community intervention to reduce patient delay time on use of reperfusion therapy for acute myocardial infarction: rapid early action for coronary treatment (REACT) trial. REACT Study Group.
Reperfusion therapy for acute myocardial infarction (AMI) is a time-dependent intervention that can reduce infarct-related morbidity and mortality. Out-of-hospital patient delay from symptom onset until emergency department (ED) presentation may reduce the expected benefit of reperfusion therapy. ⋯ Community-wide educational efforts to enhance patient response to AMI symptoms may not translate into sustained changes in reperfusion practices. However, an increased odds for early reperfusion therapy use during the initiation of the intervention and the association of early therapy with ambulance use suggest that reperfusion therapy rates can be enhanced.

Multicenter Study Comparative Study Clinical Trial
Myoglobin for early risk stratification of emergency department patients with possible myocardial ischemia.
To determine and compare the prognostic abilities of early, single-sample myoglobin measurement with that of creatine kinase-MB (CK-MB), with cardiac troponin T (cTnT), and with physician judgment in the absence of marker results among emergency department (ED) patients with possible myocardial ischemia. ⋯ The early prognostic sensitivity of myoglobin may allow identification of some high-risk patients missed by physician judgment, CK-MB, and cTnT. Myoglobin should be considered for use in the ED based on both its diagnostic and prognostic abilities.

Multicenter Study
Reliability and validity of a new five-level triage instrument.
Triage is the initial clinical sorting process in hospital emergency departments (EDs). Because of poor reproducibility and validity of three-level triage, the authors developed and validated a new five-level triage instrument, the Emergency Severity Index (ESI). The study objectives were: 1) to validate the triage instrument against ED patients' clinical resource and hospitalization needs, and 2) to measure the interrater reliability (reproducibility) of the instrument. ⋯ This five-level triage instrument was shown to be both valid and reliable in the authors' practice settings. It reproducibly triages patients into five distinct strata, from very high hospitalization/resource intensity to very low hospitalization/resource intensity.
