Best Evidence in Emergency Medicine (BEEM) Rater Scores Correlate With Publications' Future Citations.
The "BEEM" (best evidence in emergency medicine) rater scale was created for emergency physicians (EPs) to evaluate the physician-derived clinical relevance score of recently published, emergency medicine (EM)-related studies. BEEM therefore is designed to help make EPs aware of studies most likely to confirm or change current clinical practice. ⋯ To the best of our knowledge, the BEEM rater score is the only known measure of clinical relevance. It has a high interrater reliability and face validity and correlates with future citations. Future research should assess this instrument against alternative constructs of clinical relevance.

Observational Study
Near-infrared Spectroscopy Assessment of Tissue Saturation of Oxygen in Torsed and Healthy Testes.
The objective was to assess whether testicular torsion is associated with low testicular tissue saturation of oxygen (StO2 ) as measured by transscrotal near-infrared spectroscopy (NIRS) and to compare the differences in NIRS values between testicles of the same patient, both in patients with testicular torsion and in healthy controls. ⋯ While pilot animal investigations support a potential role for transscrotal NIRS for the detection of testicular torsion, this first clinical translation of animal findings reveals that the investigated, transcutaneous, reflectance geometry NIRS device failed to demonstrate symmetric oxygenation of left and right testes in healthy controls and also failed to demonstrate depressed tissue saturation of oxygen values in patients with confirmed testicular torsion. While limited by a small sample size, other problems such as inability to calibrate depth of measurement of StO2 may have led to falsely elevated readings in patients with torsion.

Using computed tomography (CT) to evaluate patients with chest symptoms is common in emergency departments (EDs). This article describes recent trends of CT use in U.S. EDs for patients presenting with symptoms common to acute pulmonary embolism (PE). ⋯ Computed tomography use in ED visits by patients with chest symptoms increased dramatically from 2001 to 2007 and seems to have leveled off in subsequent years. The low PE diagnosis-to-CT ratio suggests that EDs may need to promote evidence-based use of CT.

Emergency Medicine Residents' Self-assessments Play a Critical Role When Receiving Feedback.
Emergency medicine (EM) faculty often aim to improve resident performance by enhancing the quality and delivery of feedback. The acceptance and integration of external feedback is influenced by multiple factors. However, it is interpreted through the "lens" of the learner's own self-assessment. Ideally, following an educational activity with feedback, a learner should be able to generate and act upon specific learning goals to improve performance. Examining the source of generated learning goals, whether from one's self-assessment or from external feedback, might shed light on the factors that lead to improvement and guide educational initiatives. Using a standard oral board scenario, the objective of this study was to determine the effects that residents' self-assessment and specific feedback from faculty have on not only the generation of learning goals but also the execution of these goals for performance improvement. ⋯ Following feedback on an oral board scenario, residents generated the majority of their learning goals from their own self-assessments. Conversely, at the follow-up period, they recalled an increased number of learning goals stemming from feedback, while the largest proportion of learning goals acted upon stemmed from both feedback and self-assessments in agreement. This suggests that educators need to incorporate residents' self-assessments into any delivered feedback to have the greatest influence on future learning goals and actions taken to improve performance.

Observational Study
Parental Anxiety at Initial Acute Presentation Is Not Associated With Prolonged Symptoms Following Pediatric Concussion.
Anxiety modulates symptom perception in adults following concussion, prolonging the time to full recovery. The authors sought to determine whether parental anxiety was associated with persistent postconcussive symptoms (PCS) in their children following concussion. ⋯ Parental anxiety at time of acute presentation does not appear to be associated with prolongation of postconcussive symptoms in their children. However, parents of persistently symptomatic children remain significantly more anxious than those whose children's symptoms have resolved. Future research should attempt to reduce the familial burden of concussion through expectation management strategies.
