Comparative Study
Pandemic H1N1 influenza in the pediatric emergency department: a comparison with previous seasonal influenza outbreaks.
We compare the acuity of pediatric emergency department (ED) patients between the ongoing H1N1 influenza pandemic and previous seasonal influenza outbreaks. ⋯ The severity of illness during the 2009 H1N1 surge appeared similar to that of previous influenza seasons for the total population of the 2 pediatric tertiary care EDs, whereas an increase in the proportion of ICU admissions was observed for patients with influenza-like illness.

Meta Analysis
Emergency physician ultrasonography for evaluating patients at risk for ectopic pregnancy: a meta-analysis.
Ectopic pregnancy is a common concern in emergency departments (EDs) and remains the leading cause of first-trimester mortality. Pelvic ultrasonography by emergency physicians has been investigated as a diagnostic test for ectopic pregnancy. We present a meta-analysis of the use of emergency physician ultrasonography in the evaluation of patients at risk of ectopic pregnancy. ⋯ The results of this meta-analysis suggest that in a wide variety of clinical settings, the use of bedside ultrasonography performed by emergency physicians as a diagnostic test for ectopic pregnancy provides excellent sensitivity and negative predictive value. Visualization of an intrauterine pregnancy by an emergency physician is generally sufficient to rule out ectopic pregnancy.

Compression ultrasonography of the lower extremity is an established method of detecting proximal lower extremity deep venous thrombosis when performed by a certified operator in a vascular laboratory. Our objective is to determine the sensitivity and specificity of bedside 2-point compression ultrasonography performed in the emergency department (ED) with portable vascular ultrasonography for the detection of proximal lower extremity deep venous thrombosis. We did this by directly comparing emergency physician-performed ultrasonography to lower extremity duplex ultrasonography performed by the Department of Radiology. ⋯ Emergency physician-performed 2-point compression ultrasonography of the lower extremity with a portable vascular ultrasonographic machine, conducted in the ED by this physician group and in this patient sample, accurately identified the presence and absence of proximal lower extremity deep venous thrombosis.

There is both increasing recognition and growing scrutiny of the increased utilization of computed tomography (CT) in medicine. For our primary objective, we determine and quantify the CT utilization rate in our emergency department (ED) during the last 7 years. As a secondary objective, we compare trends in utilization for various types of CT scans. ⋯ Recent CT utilization in our ED increased in all anatomic categories assessed, with chest CTs and neck CTs increasing the most, followed by abdomen-pelvis CTs, facial bone CTs, and head CTs.
