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.

To determine the shift lengths currently worked by emergency medicine (EM) residents and their shift length preferences, and to determine factors associated with EM residents' subjective tolerance of shiftwork. ⋯ Emergency medicine residents generally tolerate shiftwork well and prefer 8-hour or 10-hour shift lengths compared with 12-hour shift lengths. Emergency medicine residencies with 12-hour shifts should consider changing residents' shifts to shorter shifts.

The emergency department (ED) visit provides an opportunity for patient education. Many ED patients have poor access to regular health care, including patient education. ⋯ More importantly, published clinical studies evaluating patient education in both the ED and comparable settings support the hypothesis that ED-based patient education improves outcomes. The article discusses considerations for instructional material, highlights challenges to ED-based patient education, and suggests possibilities for future research.

Patient satisfaction investigations and the emergency department: what does the literature say?
Patient satisfaction is an indicator of the quality of care provided by emergency department (ED) personnel. It is this perception of satisfaction that becomes the basis for future ED choice or the recommendation of a specific ED to other potential patients. ⋯ Despite considerable methodologic variability, key themes (e.g., association of satisfaction with patient information, provider-patient interpersonal factors, and perceived waiting time) emerge from review of the ED patient satisfaction literature. To standardize future investigations, clinicians and investigators should use a common definition for the state of overall patient satisfaction, e.g., when the patient's own expectations for treatment and care are met (or exceeded). This common definition should be incorporated into the instrument used to measure overall ED patient satisfaction.

To determine whether the alveolar dead space volume (V(D)alv), expressed as a percentage of the alveolar tidal volume (V(D)alv/V(T)alv), can predict the degree of vascular occlusion caused by pulmonary embolism (PE). ⋯ The V(D)alv/V(T)alv correlates with the lung perfusion defect and the pulmonary artery pressures in subjects with PE. These findings show the potential for V(D)alv/V(T)alv to quantify the embolic burden of PE.
