Randomized Controlled Trial
Use of an automated device for external chest compressions by first-aid workers unfamiliar with the device: a step toward public access?
The objective was to establish the feasibility of using an automated external chest compression (ECC) device among first-aid workers unfamiliar with the device. ⋯ An automated ECC device can be rapidly placed and used by first-aid workers unfamiliar with the device. In the light of these results, use of the device by the general public can be envisaged.

Multicenter Study
Real-time inter-rater reliability of the Council of Emergency Medicine residency directors standardized direct observation assessment tool.
Developed by the Council of Emergency Medicine Residency Directors (CORD), the standardized direct observation assessment tool (SDOT) is an evaluation instrument used to assess residents' clinical skills in the emergency department (ED). In a previous study examining the inter-rater agreement of the tool, faculty scored simulated resident-patient encounters. The objective of the present study was to evaluate the inter-rater agreement of the SDOT in real-time evaluations of residents in the ED. ⋯ The SDOT demonstrated excellent inter-rater agreement when analyzed with liberal agreement and when dichotomized as a pass/fail measure and fair to good agreement for most measures with exact agreement. The SDOT can be useful and reliable when evaluating residents' clinical skills in the ED, particularly as it relates to marginal performance.

Ultrasound (US) has been shown to facilitate peripheral intravenous (IV) placement in emergency department (ED) patients with difficult IV access (DIVA). This study sought to define patient and vein characteristics that affect successful US-guided peripheral IV placement. ⋯ Success was solely related to vessel characteristics detected with US and not influenced by patient characteristics or probe orientation. Successful DIVA was primarily associated with larger vessel, while vessel depth up to >1.6 cm and patient characteristics were unrelated to success. Clinically, if two vessels are identified at a depth of <1.6 cm, the larger diameter vessel, even if comparatively deeper, should yield the greatest likelihood of success.

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.
