To determine how the demographic, clinical, and utilization characteristics of emergency department (ED) frequent users differ from those of other ED patients. ⋯ Frequent use of the ED reflects the urban social problems of homelessness, poverty, alcohol abuse, and chronic illness. Frequent use of the ED shows a high rate of decline from one year to the next. This rate of decline slows after the first year and suggests the existence of a smaller group of chronic frequent users.

Comparative Study
Evaluation of protocols allowing emergency medical technicians to determine need for treatment and transport.
To determine whether emergency medical technicians (EMTs) can safely apply protocols to assign transport options and to assess agreement between groups of providers on application of the protocols. ⋯ From 3% to 11% of patients determined on scene not to need an ambulance had a critical event. Emergency medical services systems need to determine an acceptable rate of undertriage. Further study is needed to determine whether better adherence to the protocols might increase safety.

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.

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.
