Comparison of Web-Versus Classroom-Based Basic Ultrasonographic and EFAST Training in 2 European Hospitals

STUDY OBJECTIVE Training physicians in new skills through classroom-based teaching has inherent cost and time constraints. We seek to evaluate whether Web-based didactics result in similar knowledge improvement and retention of basic ultrasonographic principles and the Extended Focused Assessment with Sonography for Trauma (EFAST) compared with the traditional method. METHODS Physicians from 2 German emergency departments were randomized into a classroom group with traditional lectures and a Web group who watched narrated lectures online. All participants completed a pre- and posttest and a second posttest 8 weeks later. Both groups underwent hands-on training after the first posttest. A control group completed the 2 initial tests without didactic intervention. RESULTS Fifty-five subjects participated in the study. Both the classroom and Web group showed significant improvement in pre- and posttest 1 scores (75.9% versus 93.9% and 77.8% versus 92.5%; P<.001 for both), with similar knowledge retention after 8 weeks (88.6% and 88.9%; P=.87). No statistically significant difference in mean test scores could be found between the 2 groups at each point: -1.9% (95% confidence interval [CI] -5.2% to 1.4%) for the pretest, 1.4% (95% CI -0.6% to 3.4%) for posttest 1, and -0.3% (95% CI -3.9% to 3.3%) for posttest 2. The control group showed no learning effect without intervention (83.3% versus 82.8%, ; P=.88). CONCLUSION Web-based learning provides the potential to teach physicians with greater flexibility than classroom instruction. Our data suggest that Web-based ultrasonography and EFAST didactics are comparable to traditional classroom lectures and result in similar knowledge retention.

Emergency Medicine Residents Consistently Rate Themselves Higher than Attending Assessments on ACGME Milestones

Introduction In 2012 the Accreditation Council for Graduate Medical Education (ACGME) introduced the Next Accreditation System (NAS), which implemented milestones to assess the competency of residents and fellows. While attending evaluation and feedback is crucial for resident development, perhaps equally important is a resident’s self-assessment. If a resident does not accurately self-assess, clinical and professional progress may be compromised. The objective of our study was to compare emergency medicine (EM) resident milestone evaluation by EM faculty with the same resident’s self-assessment. Methods This is an observational, cross-sectional study that was performed at an academic, four-year EM residency program. Twenty-five randomly chosen residents completed milestone self-assessment using eight ACGME sub-competencies deemed by residency leadership as representative of core EM principles. These residents were also evaluated by 20 faculty members. The milestone levels were evaluated on a nine-point scale. We calculated the average difference between resident self-ratings and faculty ratings, and used sample t-tests to determine statistical significance of the difference in scores. Results Eighteen residents evaluated themselves. Each resident was assessed by an average of 16 attendings (min=10, max=20). Residents gave themselves statistically significant higher milestone ratings than attendings did for each sub-competency examined (p<0.0001). Conclusion Residents over-estimated their abilities in every sub-competency assessed. This underscores the importance of feedback and assessment transparency. More attention needs to be paid to methods by which residency leadership can make residents’ self-perception of their clinical ability more congruent with that of their teachers and evaluators. The major limitation of our study is small sample size of both residents and attendings.

Exercise-induced Anaphylaxis as a Cause of Syncope

BACKGROUND Exercise-induced anaphylaxis (EIA) is an under-recognized condition that is a distinct physical allergy. Triggers include varying amounts of exercise, alone or in combination with certain foods or medications (food-dependent EIA, or FDEIA). Therapy is identical to that of any immunoglobulin E-mediated allergic reaction. OBJECTIVES This case is reported to increase awareness among emergency physicians of EIA and FDEIA. CASE REPORT A 57-year-old man was found with a diffuse erythematous rash after eating a wheat bagel and walking up five flights of stairs. Emergency medical services found him hypotensive and combative. In the Emergency Department, the patients blood pressure was 72/27 mm Hg, with an oxygen saturation of 97% on non-rebreather mask. The physical examination was notable for bilateral inspiratory crackles in the lower one-third of the lungs. He received intravenous (i.v.) diphenhydramine 25 mg, i.v. methylprednisolone 125 mg, and 1 L of normal saline, after which his blood pressure improved to 110/54 mm Hg. He was admitted to the hospital where his recovery was uneventful. CONCLUSION EIA and FDEIA are uncommon forms of physical allergy, but they represent important entities for emergency physicians to consider. Recognition of the association with exercise is key, as recurrences can be prevented by avoiding triggers.

Evaluation and Treatment of the Elbow and Forearm Injuries in the Emergency Department

Elbow and forearm injuries result most commonly from direct blows to the area, or from fall on outstretched hand. The elbow may be injured if it is locked at the time of impact. Elbow or forearm bone dislocations may occur alone or in conjunction with fractures and generally require reduction to minimize future morbidity. The primary goal of management is to achieve anatomic reduction of any fracture or dislocation, while allowing for early range of motion to minimize future morbidity, including in particular elbow stiffness and consequently limited mobility of the joint.

Sonographic cervical motion tenderness: A sign found in a patient with pelvic inflammatory disease

No single historical, physical, laboratory, or imaging finding is both sensitive and specific for the diagnosis of pelvic inflammatory disease (PID). Cervical motion tenderness (CMT), when present, is classically found on bimanual examination of the cervix and uterus. CMT is often associated with PID but can be present in other disease entities. We present a case report of a patient who was ultimately diagnosed with acute PID. The evaluating physician performed a trans-vaginal bedside ultrasound, and the operator appreciated ‘sonographic CMT’. In cases where the physical examination is equivocal or in patients where the exact location of tenderness is difficult to discern, performing a trans-vaginal bedside ultrasound examination can increase the physicians confidence that CMT is present as the cervix is being directly visualized as pressure is applied with the probe. Bedside ultrasound and specifically sonographic CMT may prove useful in diagnosing PID in patients with equivocal or unclear physical examination findings.

Emergency Ultrasound: A Survey Study of Fellowship Graduate Characteristics and Career Paths

There are sparse data on the career pathways of graduates of emergency ultrasound fellowships. The authors sought to define the characteristics of graduates and their reported career paths after training through this survey study.

Management of Pneumothoraces Detected on Chest Computed Tomography: Can Anatomical Location Identify Patients Who Can Be Managed Expectantly?

BACKGROUND Pneumothorax (PTX) can be readily detected by computed tomography (CT) or ultrasound. However, management of PTX in hemodynamically stable patients remains controversial. STUDY OBJECTIVES We sought to investigate whether a distinct anatomical distribution of PTX along prespecified chest zones as detected by CT can be described in patients with or without subsequent chest tube thoracotomy (CTT), thus potentially allowing the extended focused assessment with sonography for trauma (EFAST) ultrasound examination to guide PTX management. METHODS We performed a retrospective review of chest CT scans performed in the emergency department (ED) of a Level I trauma center. CT scans were analyzed for PTX distribution according to a chest zone model. Medical records of subjects with PTX were reviewed for subsequent CTT. RESULTS Of 3636 chest CT scans performed, 183 PTX (156 patients) were detected without CTT at the time of CT scan (69% male, mean age 42 years). Of these, 66 subjects (40%) underwent CTT; 43 chest tubes (63%) were placed in the ED, 9 (13%) during hospitalization and 9 (13%) in the operating room. Median time to CTT was 140 min (interquartile range 52-199). Initial hemodynamic parameters, need for surgery, and need for mechanical ventilation were similar in both groups (p > 0.05 for all). Anatomical distribution and size of PTX were similar in the two groups. CONCLUSION Although the majority of patients with traumatic PTX could be managed conservatively, we did not identify a characteristic anatomical PTX pattern, which could identify subjects who may not require CTT.
