Comparative Study Observational Study
Feasibility and Diagnostic Accuracy of Brief Health Literacy and Numeracy Screening Instruments in an Urban Emergency Department.
The objective was to evaluate the diagnostic accuracy of five health literacy screening instruments in emergency department (ED) patients: the Rapid Evaluation of Adult Literacy in Medicine-Revised (REALM-R), the Newest Vital Sign (NVS), Single Item Literacy Screens (SILS), health numeracy, and physician gestalt. A secondary objective was to evaluate the feasibility of these instruments as measured by administration time, time on task, and interruptions during test administration. ⋯ One-quarter of these ED patients had marginal or inadequate health literacy. Among the brief screening instruments evaluated, a normal NVS result accurately reduced the probability of LHL, although it will identify two-thirds of ED patients as high risk for LHL. None of the brief screening instruments significantly increases the probability of LHL when abnormal.

Scaphoid fractures are the most common carpal fracture, representing 70% of carpal bone fractures. The diagnostic accuracy of physical examination findings and emergency medicine (EM) imaging studies for scaphoid fracture has not been previously described in the EM literature. Plain x-rays are insufficient to rule out scaphoid fractures in a patient with a suggestive mechanism and radial-sided tenderness on physical examination. This study was a meta-analysis of historical features, physical examination findings, and imaging studies for scaphoid fractures not visualized on plain x-ray in adult emergency department (ED) patients, specifically to address which types of imaging tests should be recommended in patients with persistent concern for acute fracture after ED discharge. ⋯ Except for the absence of snuffbox tenderness, which can significantly reduce the probability of scaphoid fracture, history and physical examination alone are inadequate to rule in or rule out scaphoid fracture. MRI is the most accurate imaging test to diagnose scaphoid fractures in ED patients with no evidence of fracture on initial x-rays. If MRI is unavailable, CT is adequate to rule in scaphoid fractures, but inadequate for ruling out scaphoid fractures.

Dog bite injuries may result in pain, infection, emotional distress, dysfunction, and disfiguration, as well as lead to costly health care utilization, such as emergency department (ED) visits, rabies postexposure prophylaxis, and hospitalizations. Although clinical care guidelines exist, to our knowledge risk factors for hospitalization after a dog bite injury have not been examined quantitatively. Quantifying the magnitude of association between modifiable risk factors, such as infection, and hospitalization after a dog bite injury may guide intervention efforts, improve patient outcomes, and reduce unnecessary hospitalizations. ⋯ This study provides a unique, quantitative examination of risk factors for hospitalization after dog bite injury. The relative risk of hospitalization associated with each factor was substantial. The strongest association was for a modifiable risk factor, infection. This finding may inform best practices for initial care of patients with dog bite injuries and the development of novel protocols for following patients to reduce infections and subsequent hospitalizations.

Multicenter Study Comparative Study Observational Study
Procalcitonin as a Marker of Serious Bacterial Infections in Febrile Children Younger Than 3 Years Old.
There is no perfectly sensitive or specific test for identifying young, febrile infants and children with occult serious bacterial infections (SBIs). Studies of procalcitonin (PCT), a 116-amino-acid precursor of the hormone calcitonin, have demonstrated its potential as an acute-phase biomarker for SBI. The objective of this study was to compare performance of serum PCT with traditional screening tests for detecting SBIs in young febrile infants and children. ⋯ Procalcitonin is a more accurate biomarker than traditional screening tests for identifying young febrile infants and children with serious SBIs. Further study on a larger cohort of young febrile children is required to definitively determine the benefit of PCT over traditional laboratory screening tests for SBIs.
