Multicenter Study Comparative Study
Performance of ultrasound in the diagnosis of appendicitis in children in a multicenter cohort.
The objectives were to assess the test characteristics of ultrasound (US) in diagnosing appendicitis in children and to evaluate site-related variations based on the frequency of its use. Additionally, the authors assessed the test characteristics of US when the appendix was clearly visualized. ⋯ Ultrasound sensitivity and the rate of visualization of the appendix on US varied across sites and appeared to improve with more frequent use. US had universally high sensitivity and specificity when the appendix was clearly identified. Other diagnostic modalities should be considered when the appendix is not definitively visualized by US.

The Accreditation Council for Graduate Medical Education (ACGME) has outlined its "Next Accreditation System" (NAS) that will focus on resident and residency outcome measurements. Emergency medicine (EM) is one of seven specialties that will implement the NAS beginning July 2013. All other specialties will follow in July 2014. ⋯ Milestones describe competencies more specifically and identify specialty-specific knowledge, skills, attitudes, and behaviors (KSABs) that can be used as outcome measures within the general competencies. The ACGME and the American Board of Emergency Medicine (ABEM) convened an EM milestone working group to develop the EM milestones. This article describes the development, use within the NAS, and challenges of the EM milestones.

Comparative Study
Sex preferences in cardiovascular testing: the contribution of the patient-physician discussion.
Prior studies suggest that a decreased cardiac catheterization rate for women with acute coronary syndrome (ACS) is partially attributed to gender differences in patient preferences for testing. The hypothesis was that these preferences are influenced by physician recommendations for cardiovascular testing. ⋯ Women who presented to the ED with symptoms concerning for ACS reported lower rates of physician recommendation for cardiovascular testing, as well as lower rates of counseling regarding cardiac etiologies of their chest pain. These findings suggest sex differences in preference for cardiovascular testing may be partially explained by the discussions between women and their doctors.

To the authors' knowledge, no prospectively validated, biomarker-based risk stratification tools exist for elderly patients presenting to the emergency department (ED) with nonspecific complaints (NSCs), such as generalized weakness, despite the fact that an acute serious disease often underlies nonspecific disease presentation. The primary purpose for this study was to validate the retrospectively derived model for outcome prediction using copeptin and peroxiredoxin 4 (Prx4), in a different group of patients, in a prospective fashion, in a multicenter setting. The secondary goals were to evaluate the potential contribution of the midregional portion of the precursor of adrenomedullin (MR-proADM) for outcome prediction and to investigate whether disposition decisions show promise for potential improvement by using biomarker levels in addition to a clinical assessment. ⋯ In this study the authors confirm that these new stress biomarkers permit reliable prognostication of adverse outcomes in a heterogeneous group of patients with NSCs. A simulation showed that this prognostic information could be useful to enhance the appropriateness of disposition decisions of ED patients with NSC. The use of biomarkers for risk stratification in this patient group should be evaluated with prospective intervention studies.
