Background:Before a trial testing prehospital teleconsultation for children, we studied acceptability, feasibility, and workload after integrating teleconsultation into Emergency Medical Service (EMS) workflows. Methods:We randomized paramedic-physician teams to teleconsultation (audio/video call, intervention) or usual care (audio call, control) for three simulated pediatric transports using mixed methods. Paramedic dyads provided in-ambulance simulated care while remote pediatric emergency physicians offered real-time consultation. In the intervention group, we used the Telehealth Usability Questionnaire to measure acceptability [primary; Total Usability Score (TUS), maximum = 7] and feasibility [secondary; Interaction Quality Score (IQS)]; and interviews for Technology Acceptance Model themes. Between groups, we calculated descriptive statistics and compared connection success and workload. Results:Twenty-four teams (12/group) completed 72 simulated transports. Intervention paramedics attempted physician contact in 94% (34/36) of transports versus 47% (17/36) in control; 92% connected in ≤2 attempts. In the intervention group, mean TUS was 5.6 (95% CI 5.2, 6.0) for physicians and 5.8 (95% CI 5.5, 6.0) for paramedics; mean IQS was 5.2 (95% CI 4.6, 6.0) and 5.9 (95% CI 5.4, 6.3) respectively. Intervention paramedics reported similar workload to controls (p = 0.26) but less frustration (p = 0.03); physicians experienced higher workload (p = 0.01). Interviews identified improved communication and physician involvement, alongside uncertainty about physician roles and impact on paramedic autonomy. Video quality was adequate, but concerns about real-world audio and broadband reliability remained. Conclusions:In simulations, teleconsultation for pediatric EMS transports was acceptable and feasible with minor technical modifications. Implementation should balance physician workload and clarify roles through training. Future trials should evaluate patient outcomes.

Objective: This study aims to evaluate the potential impact of addressing goals-of-care (GOC) with selected patients in the emergency department (ED), GOC documentation, hospital utilization, and patient satisfaction. Method: This is a single-center, retrospective, and prospective, observational convenience-sample study. ED registered nurses (ED RNs) received standardized GOC conversation training. Their selection criteria included a selection interview, a minimum of 3 years of ED clinical experience, and current employment in the ED. ED RNs used a standardized GOC questionnaire. Patient inclusion criteria included age ≥18 years and one or more of the following: chronic kidney disease ≥ stage III, congestive heart failure with an ejection fraction ≤ 40%, chronic obstructive pulmonary disease with home oxygen use, and/or malignancy with metastasis. GOC conversations were recorded in the electronic medical record (EMR). Physician Orders for Life-Sustaining Treatment (POLST) forms were completed as appropriate. Select individual patient data for the 12 months prior to the conversation were compared with the following 12 months. Results: Over 6 months, 94 of 133 patients who were approached consented to the GOC discussion with the RN. All 94 enrolled patients had their GOC recorded into the EMR. One-third already had a completed POLST form prior to ED arrival. 50% without a POLST on ED arrival left with a completed POLST. Eighty-four patients survived the index visit and 46 patients survived to study completion. Patient satisfaction with the interaction was high: In the cohort who survived past the index visit, 95% rated their experience at 4/5 or 5/5 (Likert scale, 5: strongly agree, 1: strongly disagree). In the survival-to-study completion cohort, 100% rated their experience as 4/5 or 5/5. Subsequent median ED visits decreased by 15% (1.0-4.0 interquartile range). There were no statistically significant changes in hospitalizations (both decreased by 25%, 0-3.0) or intensive care unit admissions (0%, 0-0). Conclusions: An ED RN-led GOC conversation had high patient satisfaction and 100% GOC documentation in the EMR. There was a significant increase in ED POLST form completion. There were no significant changes noted in subsequent hospitalizations, length of hospitalization, or intensive care unit utilization.

Introduction Simulation tools to assess prehospital team performance and identify patient safety events are lacking. We adapted a simulation model and checklist tool of individual paramedic performance to assess prehospital team performance and tested interrater reliability. Methods We used a modified Delphi process to adapt 3 simulation cases (cardiopulmonary arrest, seizure, asthma) and checklist to add remote physician direction, target infants, and evaluate teams of 2 paramedics and 1 physician. Team performance was assessed with a checklist of steps scored as complete/incomplete by raters using direct observation or video review. The composite performance score was the percentage of completed steps. Interrater percent agreement was compared with the original tool. The tool was modified, and raters trained in iterative rounds until composite performance scoring agreement was 0.80 or greater (scale <0.20 = poor; 0.21–0.39 = fair, 0.40–0.59 = moderate; 0.60–0.79 = good; 0.80–1.00 = very good). Results We achieved very good interrater agreement for scoring composite performance in 2 rounds using 6 prehospital teams and 4 raters. The original 175 step tool was modified to 171 steps. Interrater percent agreement for the final modified tool approximated the original tool for the composite checklist (0.80 vs. 0.85), cardiopulmonary arrest (0.82 vs. 0.86), and asthma cases (0.80 vs. 0.77) but was lower for the seizure case (0.76 vs. 0.91). Most checklist items (137/171, 80%) had good–very good agreement. Among 34 items with fair-moderate agreement, 15 (44%) related to patient assessment, 9 (26%) equipment use, 6 (18%) medication delivery, and 4 (12%) cardiopulmonary resuscitation quality. Conclusions The modified checklist has very good agreement for assessing composite prehospital team performance and can be used to test effects of patient safety interventions.

More than 85% of blunt and penetrating trauma to the thorax results in injury to the lungs or ribs. Among civilians, blunt trauma is the most common mechanism, while penetrating trauma is the most common among military sectors. This review describes the assessment and stabilization, diagnosis, treatment and disposition, and outcomes of thoracic trauma. Videos shows the “lung point” sign on M-mode and two-dimensional ultrasonography, and a transthoracic echocardiogram clip of pericardial clot and tamponade due to a gunshot wound. Figures show a sonogram showing the “lung point sign”, a chest x-ray and computed tomographic scan demonstrating right-sided hemothorax in a patient with a right chest stab wound, and a three-dimensional computed tomographic scan and chest x-ray of a blunt trauma patient with displaced fractures of the left lateral sixth to ninth ribs. Tables list types of injuries, NEXUS chest decision instrument imaging criteria, level 2 evidence-based recommendations for the management of pulmonary contusion and flail chest by the Eastern Association for the Surgery of Trauma, Eastern Association for the Surgery of Trauma practice guidelines for managing issues with pulmonary contusion and flail chest, and the Vancouver simplified and University of Washington grading systems for blunt aortic injury. This review contains 2 videos, 4 highly rendered figures, 10 tables, and 94 references.

Simulation has been steadily changing the safety culture in the healthcare industry and allowing individual clinicians and interdisciplinary teams to be proactive in the culture of risk reduction and improved patient safety. Literature has demonstrated improved patient outcomes, improved team based skills, systems testing and mitigation of latent safety threats. Simulation may be incorporated into practice via different modalities. The simulation lab is helpful for individual procedures, in situ simulation (ISS) for system testing and teamwork, community outreach ISS for sharing of best practices and content resource experts. Serious medical gaming is developing into a useful training adjunct for the future.

BACKGROUND:Simulation-based education is an important tool in the training of professionals in the medical field, especially for low-frequency, high-risk events. An interprofessional simulation-based training program was developed to enhance Emergency Airway Response Team (EART) knowledge, team dynamics, and personnel confidence. This quality improvement study evaluated the EART simulation training results of nurse participants.METHOD:Twenty-four simulation-based classes of 4-hour sessions were conducted during a 12-week period. Sixty-three nurses from the emergency department (ED) and the intensive care units (ICUs) completed the simulation. Participants were evaluated before and after the simulation program with a knowledge-based test and a team dynamics and confidence questionnaire. Additional comparisons were made between ED and ICU nurses and between nurses with previous EART experience and those without previous EART experience.RESULTS:Comparison of presimulation (presim) and postsimulation (postsim) results indicated a statistically significant gain in both team dynamics and confidence and Knowledge Test scores (P < .01). There were no differences in scores between ED and ICU groups in presim or postsim scores; nurses with previous EART experience demonstrated significantly higher presim scores than nurses without EART experience, but there were no differences between these nurse groups at postsim.CONCLUSIONS:This project supports the use of simulation training to increase nurses' knowledge, confidence, and team dynamics in an EART response. Importantly, nurses with no previous experience achieved outcome scores similar to nurses who had experience, suggesting that emergency airway simulation is an effective way to train both new and experienced nurses.

Within the next 15 years, 1 in 5 Americans will be over age 65. $34 billion will be spent yearly on trauma care of this age group. This section covers situations in trauma unique to the geriatric population, who are often under-triaged and have significant injuries underestimated. Topics covered include age-related pathophysiological changes, underlying existing medical conditions and certain daily medications that increase the risk of serious injury in elderly trauma patients. Diagnostic evaluation of this group requires liberal testing, imaging, and a multidisciplinary team approach. Topics germane to geriatric trauma including hypothermia, elder abuse, and depression and suicide are also covered.

• Bruit or thrill suggestive of a traumatic arteriovenous fistula • Expanding or pulsatile hematoma • Pulsatile or severe hemorrhage • Pulse deficit—pulses may be normal in patients with nonocclusive injuries that require surgical repair, such as intimal flaps or pseudoaneurysms • Thorough vascular and esophageal evaluation is required, even with minor neck wounds, if any abnormalities are evident on examination or radiographs. • Radiographs do not rule out esophageal injury. • Early airway management is crucial, with orotracheal intubation being the initial method of choice. • A thorough neurologic examination is essential in all patients with neck trauma. • “Hard signs” of vascular injury include bruit, thrill, expanding or pulsatile hematoma, pulsatile or severe hemorrhage, pulse deficit, and central nervous system ischemia. • The “gold standard” for diagnosing vascular injury is conventional angiography. • Admission criteria include signs and symptoms of organ damage and penetration of the platysma muscles. KEY POINTS

Patients with moderate to severe head injury and abnormal coagulation studies have a significantly higher risk of brain injury. The objective of this study was to determine the association of clinical suspicion of coagulopathy and intracranial injury (ICI) among patients sustaining blunt head trauma, including minor injuries. As part of the NEXUS II blunt head injury study, enrolled patients were prospectively evaluated for ICI and suspicion of coagulopathy. We examined the relationship between suspicion of coagulopathy and the presence of any clinically significant or “therapeutically inconsequential” ICI based on head computed tomography (CT) scan results. The NEXUS II study enrolled 13,728 patients, including 493 with suspicion of coagulopathy. Significant ICI was present in 46 (9.3%; 95% confidence interval [CI] 6.9–12.2) patients with suspected coagulopathy, and in 460 of 9863 (4.7%; 95% CI 4.3–5.1) patients without such suspicion. “Therapeutically inconsequential” findings were found on head CT scan in 74 patients, and 7 of these had suspected coagulopathy. Interventions including intubation, intracranial pressure monitoring, or craniotomy were performed in 5 of these 7 (71%; 95% CI 29–96) individuals, compared with only 3 of 67 (4%; 95% CI 1–12) patients without suspicion of coagulopathy. Initial clinical suspicion of coagulopathy, independent of laboratory confirmation, is associated with a greater prevalence of significant ICI injury after blunt head trauma; it also substantially increases the risk of morbidity despite the presence of an apparent “therapeutically inconsequential” injury. CT scanning of the head should be performed initially based on clinical suspicion of coagulopathy.

Airway management in obese adults can be challenging, and much of the literature on this subject focuses on elective surgical cases, rather than acutely ill patients In this article, we review the emergency department evaluation of the airway in obesity, discussing anatomy, physiology, and pharmacology In addition, we describe techniques and devices used to improve intubating conditions in the obese patient. After our review of the relevant literature, we conclude that research in this particular area of acute care remains in its infancy. [Ann Emerg Med 2010;56:95-104.]

Introduction: A number of devices, including video laryngoscopy, are used to aid in managing difficult airways. The goal of this study was to compare timing and success of video laryngoscopy to standard laryngoscopic intubation using a simulation mannequin in normal and difficult airway scenarios. Methods: Residents and attending physicians of a PGY 2–4 emergency medicine residency program participated. A single, high-fidelity simulation mannequin was used. Each participant received an in-service on the video laryngoscope (GlideScope). Three airway settings were used: standard, decreased neck mobility, and tongue edema. Participants intubated with a Macintosh blade and video laryngoscope in each scenario, and graded the best view achieved using the Cormack-Lehane classification. Outcome measures included time to view the vocal cords, time to intubation, grading of view, and intubation success or failure. Institutional Review Board approval was obtained. Results: Fifty-two participants were enrolled. Participants successfully intubated the mannequin faster using the Macintosh blade in both the normal and neck immobility settings (9.4 seconds faster, 95% CI 3.2–15.7, P = 0.004, 16.1 seconds faster, 95% CI 3.6–28.7, P = 0.01). In the tongue edema setting, however, video laryngoscopy provided a better grade view of the cords, a higher success rate of viewing the cords at time of intubation (50% vs. 12%), and a higher rate of successful intubations (83% vs. 23%). The GlideScope also significantly reduced the time needed to view the cords (89 seconds reduction, 95% CI 54.4–123.7, P < 0.0001) and intubate (131.3 seconds reduction, 95% CI 99.1–163.6, P< 0.0001) for the tongue edema setting. Conclusions: In the most difficult airway case, tongue edema, the video laryngoscope provided an enhanced view of the cords using less time, increased intubation success, and decreased the time to intubation.

Developing technical expertise in medical procedures is an integral component of emergency medicine (EM) practice and training. This article is the work of an expert panel composed of members from the Society for Academic Emergency Medicine (SAEM) Interest Group, the SAEM Technology in Medical Education Committee, and opinions derived from the May 2008 Academic Emergency Medicine Consensus Conference, "The Science of Simulation in Healthcare." The writing group reviewed the simulation literature on procedures germane to EM training, virtual reality training, and instructional learning theory as it pertains to skill acquisition and procedural skills decay. The authors discuss the role of simulation in teaching technical expertise, identify training conditions that lead to effective learning, and provide recommendations for future foci of research.

ABSTRACT Scrofula, or tuberculous cervical lymphadenitis, though now rare, is more commonly seen in minorities, women and immunosuppressed patients, especially those with HIV. We discuss a patient who presented to the emergency department with an anterior neck abscess and was diagnosed with both advanced HIV and disseminated tuberculosis. A high level of suspicion is necessary to make this diagnosis, but given an increasing degree of global mobility, such patients may present anywhere. Medical management is effective, though difficult. Early diagnosis improves the patient's individual prognosis and may prevent further exposure and transmission to the population.

Study objective: We examine the prevalence and types of intracranial injuries sustained by intoxicated blunt trauma patients.Methods: The study was conducted as a secondary analysis of National Emergency X-Radiography Utilization Study II head injury database. Treating physicians prospectively assessed presenting signs and symptoms on all blunt trauma patients who underwent head computed tomography (CT). Intoxication status was determined by the examining physician and was based on a history of intoxication, positive toxicologic screen result, or physical evidence suggesting intoxication. Intracranial injury diagnoses were based on final CT interpretations provided by attending radiologists.Results: Intracranial injury was detected in 1,193 of the 13,728 enrolled patients (8.7%), and intoxication was evident in 3,356 (24.4%) patients. Physicians were unable to assess intoxication status in 620 individuals. Intracranial injury was present in 231 intoxicated patients (231/3,356; 6.9%; 95% confidence interval [CI] 6.0 to 7.8), 789 of 9,752 nonintoxicated patients (8.1%; 95% CI 7.6% to 8.6%), and 173 of the 620 patients who could not be assessed for intoxication (prevalence 27.9%; 95% Cl 24.4% to 31.6%). Intracranial injury was identified in only 5 of 299 intoxicated patients (1.7%) who had normal neurological examination results and no evidence of trauma to the calvarium.Conclusion: The prevalence of intracranial injury among intoxicated blunt trauma patients who are selected for head CT is lower than among nonintoxicated patients selected for imaging, which likely represents heightened concern in the presence of intoxication, even without other findings suggestive of intracranial injury. This conclusion is supported by the fact that few intoxicated patients with normal neurologic findings and no evidence of trauma to the calvarium had positive findings on CT imaging.
