Comparative Study
Use of the visual analog scale to rate and monitor severity of nausea in the emergency department.
The objective was to describe the association between verbal descriptors of nausea severity and visual analog scale (VAS) ratings in an undifferentiated emergency department (ED) population and to calculate the minimum clinically significant difference (MCSD) in VAS rating of nausea severity in this population. ⋯ There is very good correlation between verbal descriptors of nausea and VAS ratings. The MCSD for VAS nausea ratings in an ED population is 22 mm.

Comparative Study
Using a discrete-event simulation to balance ambulance availability and demand in static deployment systems.
To improve ambulance response time, matching ambulance availability with the emergency demand is crucial. To maintain the standard of 90% of response times within 9 minutes, the authors introduce a discrete-event simulation method to estimate the threshold for expanding the ambulance fleet when demand increases and to find the optimal dispatching strategies when provisional events create temporary decreases in ambulance availability. ⋯ Strategies of capacity management based on this model improved response times. The more ambulances that are out of routine duty, the better the performance of the optimal strategies that are based on this model.

Little empiric evidence exists to guide emergency department (ED) disposition of patients presenting with soft tissue infections. This study's objective was to generate a clinical decision rule to predict the need for greater than 24-hour hospital admission for patients presenting to the ED with soft tissue infection. ⋯ Although we were unable to generate a high-sensitivity decision rule to identify ED patients with soft tissue infection requiring >24-hour admission, the presence of a fever (either by initial ED vital signs or by history) was the strongest predictor of need for >24-hour hospital stay. These findings may help guide disposition of patients presenting to the ED with nonfacial soft tissue infections.

Recent position statements from health care organizations have placed a strong emphasis on continuous quality improvement (CQI). CQI finds many of its roots in kaizen, which emphasizes small, low-cost, low-risk improvements. Based on the successful Kaizen Programs at organizations such as Toyota, the authors thought the emergency department (ED) would be an ideal environment to benefit from such a program. ⋯ Over the past 4 years, the Kaizen Program at Vanderbilt has been widely and frequently used within the ED. It has resulted in over 400 changes in our adult ED system and has met the challenge of using CQI to drive ED improvements. There are limitations to this study, including the fact that its impact on patient outcomes remains unknown. However, this Kaizen Program may be an excellent tool for other departments to assist with quality improvement and should be studied with a multicenter prospective approach.

Comparative Study
Variation in the type, rate, and selection of patients for out-of-hospital airway procedures among injured children and adults.
The objective was to compare the type, rate, and selection of injured patients for out-of-hospital airway procedures among emergency medical services (EMS) agencies in 10 sites across North America. ⋯ Among 10 sites across North America, there was wide variation in the types of out-of-hospital airway procedures performed, population-based rates of airway intervention, and the selection of injured patients for such procedures.
