Cost and radiation risk have prompted intense examination of trauma patient imaging. A proposed decision instrument (DI) for the use of chest computed tomography (CT), (CCT) in blunt trauma patients includes thoracic spine (TS) tenderness, altered mental status (AMS) and distracting painful injury (DPI) as potential predictor variables. TS CT is a separate, costly study whose value is currently ill-defined. The objective of this study is to determine test characteristics of these predictor variables alone, and in combination, to derive a TS injury DI. ⋯ TS CT is low yield and costly. Patients who are alert, have no TS tenderness and no DPI have a very low likelihood of TS injury (NPV 99.7% 95% CI lower limit 98.7%) with -LR=0.07, 95% CI upper limit 0.28). Avoiding TS CT may save considerable charges and payments.

Traumatic brain injury (TBI) is a significant health concern. While 70-90% of TBI cases are considered mild, decision-making regarding imaging can be difficult. This survey aimed to assess whether clinicians' decision-making was consistent with the most recent American College of Emergency Physicians (ACEP) clinical recommendations regarding indications for a non-contrast head computed tomography (CT) in patients with mild TBI. ⋯ Respondents poorly differentiated the "older" patients from one another, suggesting that respondents either inappropriately apply the guidelines or are unaware of the recommendations in this setting. No particular cause for inconsistency could be determined, and respondents similarly under-scanned and over-scanned in incorrect vignettes. Improved dissemination of the ACEP clinical policy and recommendations is a potential solution to this problem.

To provide an epidemiological description of radial head subluxation, also known as nursemaid's elbow, from a database of emergency department visits. ⋯ The average age of children presenting with nursemaid's elbow was 28.6 months. Females were affected more than males, and the left arm was predominately affected. Most patients were above the 75(th) percentile for weight and more than one quarter were over the 95(th) percentile for weight.

The Pediatric Emergency Department (PED) provides medical students with learning in a high-volume, fast-paced environment; characteristics that can be stressful for new students. Shadowing can improve transitioning, yet this alone does not facilitate students' development of independent medical care competencies. This study evaluates if third-year medical students' deliberate apprenticeship with senior residents increases students' comfort and patient exposure in the PED. ⋯ DA constitutes a feasible approach to the clinical learning environment that increases students' patient care experiences and may ease transitioning for undergraduate medical students to new clinical environments.

Comparative Study
Improving community understanding of medical research: audience response technology for community consultation for exception to informed consent.
The Department of Health and Human Services and Food and Drug Administration described guidelines for exception from informed consent (EFIC) research. These guidelines require community consultation (CC) events, which allow members of the community to understand the study, provide feedback and give advice. A real-time gauge of audience understanding would allow the speaker to modify the discussion. The objective of the study is to describe the use of audience response survey (ARS) technology in EFIC CCs. ⋯ The use of an audience response system during the community consultation aspects of EFIC is feasible and provides a real-time assessment of audience comprehension of the study and EFIC process. It may improve the community's opinion and support of the study.
