Do topical antibiotics help prevent infection in minor traumatic uncomplicated soft tissue wounds

b h i e o e a i s s 3 [Ann Emerg Med. 2013;61:86-88.] Editor’s Note: Emergency physicians must often make decisions about patient management without clear-cut data of sufficient quality to support clinical guidelines or evidence-based reviews. Topics in the Best Available Evidence section must be relevant to emergency physicians, are formally peer reviewed, and must have a sufficient literature base to draw a reasonable conclusion but not such a large literature base that a traditional ”evidence-based” review, meta-analysis, or systematic review can be performed.

Intra-articular Lidocaine Injection for Shoulder Reductions: A Clinical Review.

Context: The shoulder is the most commonly dislocated joint, and shoulder dislocations are very common in sports. Many of these dislocations present to the office or training room for evaluation. Usual practice is an attempt at manual reduction without analgesia and then transfer to the emergency department if unsuccessful. The clinical efficacy of intra-articular lidocaine for reduction of anterior shoulder dislocations in the outpatient setting was examined. Evidence Acquisition: An OVID MEDLINE search (1966-present) was performed using the keywords shoulder, reduction, and analgesia as well as shoulder, intra-articular, and lidocaine. Search limits included articles in the English language. Bibliographic references from these articles were also examined to identify pertinent literature. Results: Six randomized controlled clinical trials were identified that directly addressed this clinical technique. Although the reduction techniques used in these studies were not controlled, there was no statistically significant difference in success rates between groups. The complication rate, length of stay, and costs were significantly less in the intra-articular lidocaine group when compared with the intravenous sedation group. Conclusions: According to current evidence, the use of intra-articular lidocaine injection for reduction of anterior shoulder dislocations is not harmful and is likely advantageous in the outpatient clinical setting.

Sonographic Inferior Vena Cava Measurements to Assess Hydration Status in College Football Players During Preseason Camp

The purpose of this study was to determine whether sonographic measurement of the inferior vena cava (IVC) in college football players during preseason camp is a reliable way to detect and monitor dehydration. Our primary hypothesis was that IVC diameter measurements, the postpractice caval index, and expiratory diameter were significantly related to percent weight loss after a preseason football practice.

Development of a novel sports medicine rotation for emergency medicine residents

Musculoskeletal complaints are the most common reason for patients to visit a physician, yet competency in musculoskeletal medicine is invariably reported as a deficiency in medical education in the USA. Sports medicine clinical rotations improve both medical students’ and residents’ musculoskeletal knowledge. Despite the importance of this knowledge, a standardized sports medicine curriculum in emergency medicine (EM) does not exist. Hence, we developed a novel sports medicine rotation for EM residents to improve their musculoskeletal educational experience and to improve their knowledge in musculoskeletal medicine by teaching the evaluation and management of many common musculoskeletal disorders and injuries that are encountered in the emergency department. The University of Arizona has two distinct EM residency programs, South Campus (SC) and University Campus (UC). The UC curriculum includes a traditional 4-week orthopedic rotation, which consistently rated poorly on evaluations by residents. Therefore, with the initiation of a new EM residency at SC, we replaced the standard orthopedic rotation with a novel sports medicine rotation for EM interns. This rotation includes attendance at sports medicine clinics with primary care and orthopedic sports medicine physicians, involvement in sport event coverage, assigned reading materials, didactic experiences, and an on-call schedule to assist with reductions in the emergency department. We analyzed postrotation surveys completed by residents, postrotation evaluations of the residents completed by primary care sports medicine faculty and orthopedic chief residents, as well as the total number of dislocation reductions performed by each graduating resident at both programs over the last 5 years. While all residents in both programs exceeded the ten dislocation reductions required for graduation, residents on the sports medicine rotation had a statistically significant higher rate of satisfaction of their educational experience when compared to the traditional orthopedics rotation. All SC residents successfully completed their sports medicine rotation, had completed postrotation evaluations by attending physicians, and had no duty hour violations while on sports medicine. In our experience, a sports medicine rotation is an effective alternative to the traditional orthopedics rotation for EM residents.

Blood Glucose Levels After Local Musculoskeletal Steroid Injections in Patients With Diabetes Mellitus: A Clinical Review:

Context: Diabetes mellitus (DM) has become an epidemic in the United States and is associated with increased risk of multiple comorbidities, including painful musculoskeletal conditions. A common treatment for many of these painful musculoskeletal conditions is local soft tissue and intra-articular corticosteroid injection (CSI). These local injections have the potential to cause elevated blood glucose levels (BGLs) and cause complications in patients with DM. Therefore, it was the objective of this investigation to review the currently available evidence that directly addresses the effects of local CSIs used for painful musculoskeletal conditions on BGL in patients with DM. Evidence Acquisition: PubMed, Google Scholar, EMBASE, CINAHL, and Cochrane Review databases were searched with a combination of the terms corticosteroid, glucocorticoid, steroid, injection, musculoskeletal, and diabetes. Search limits included the English language. Bibliographic references from these articles were also examined to identify pertinent literature. Study Design: Clinical review. Level of Evidence: Level 3. Results: Ten studies that met the inclusion criteria were reviewed. All these studies showed significant but transient increases in postinjection BGL after a single local CSI in patients with DM. There were no adverse reactions or complications reported. Conclusion: Single, local soft tissue and intra-articular musculoskeletal CSIs are most likely safe in patients with well-controlled DM.

Does Spanish instruction for emergency medicine resident physicians improve patient satisfaction in the emergency department and adherence to medical recommendations

Background After emergency department (ED) discharge, Spanish-speaking patients with limited English proficiency are less likely than English-proficient patients to be adherent to medical recommendations and are more likely to be dissatisfied with their visit. Objectives To determine if integrating a longitudinal medical Spanish and cultural competency curriculum into emergency medicine residency didactics improves patient satisfaction and adherence to medical recommendations in Spanish-speaking patients with limited English proficiency. Methods Our ED has two Emergency Medicine Residency Programs, University Campus (UC) and South Campus (SC). SC program incorporates a medical Spanish and cultural competency curriculum into their didactics. Real-time Spanish surveys were collected at SC ED on patients who self-identified as primarily Spanish-speaking during registration and who were treated by resident physicians from both residency programs. Surveys assessed whether the treating resident physician communicated in the patient’s native Spanish language. Follow-up phone calls assessed patient satisfaction and adherence to discharge instructions. Results Sixty-three patients self-identified as primarily Spanish-speaking from August 2014 to July 2015 and were initially included in this pilot study. Complete outcome data were available for 55 patients. Overall, resident physicians spoke Spanish 58% of the time. SC resident physicians spoke Spanish with 66% of the patients versus 45% for UC resident physicians. Patients rated resident physician Spanish ability as very good in 13% of encounters – 17% for SC versus 5% for UC. Patient satisfaction with their ED visit was rated as very good in 35% of encounters – 40% for SC resident physicians versus 25% for UC resident physicians. Of the 13 patients for whom Spanish was the language used during the medical encounter who followed medical recommendations, ten (77%) of these encounters were with SC resident physicians and three (23%) encounters were with UC resident physicians. Conclusion Preliminary data suggest that incorporating Spanish language and cultural competency into residency training has an overall beneficial effect on patient satisfaction and adherence to medical recommendations in Spanish-speaking patients with limited English proficiency.

An innovative longitudinal curriculum to increase emergency medicine residents' exposure to rarely encountered and technically challenging procedures.

Background Procedural skills have historically been taught at the bedside. In this study, we aimed to increase resident knowledge of uncommon emergency medical procedures to increase residents’ procedural skills in common and uncommon emergency medical procedures and to integrate cognitive training with hands-on procedural instruction using high- and low-fidelity simulation. Methods We developed 13 anatomically/physiologically-based procedure modules focusing on uncommon clinical procedures and/or those requiring higher levels of technical skills. A departmental expert directed each session with collaboration from colleagues in related subspecialties. Sessions were developed based on Manthey and Fitch’s stages of procedural competency including 1) knowledge acquisition, 2) experience/technical skill development, and 3) competency evaluation. We then distributed a brief, 10-question, online survey to our residents in order to solicit feedback regarding their perceptions of increased knowledge and ability in uncommon and common emergency medical procedures, and their perception of the effectiveness of integrated cognitive training with hands-on instruction through high- and low-fidelity simulation. Results Fifty percent of our residents (11/22) responded to our survey. Responses indicated the procedure series helped with understanding of both uncommon (65% strongly agreed [SA], 35% agreed [A]) and common (55% SA, 45% A) emergency medicine procedures and increased residents’ ability to perform uncommon (55% SA, 45% A) and common (45% SA, 55% A) emergency medical procedures. In addition, survey results indicated that the residents were able to reach their goal numbers. Conclusion Based on survey results, the procedure series improved our residents’ perceived understanding of and perceived ability to perform uncommon and more technically challenging procedures. Further, results suggest that the use of a cognitive curriculum model as developed by Manthey and Fitch is adaptable and could be modified to fit the needs of other medical specialties.

The Significance of Incidental Findings on Computed Tomography of the Chest

BACKGROUND Computed tomography (CT) of the chest has replaced lung scans and pulmonary angiography as the criterion standard for the diagnosis of pulmonary embolism (PE). Most of these examinations are negative for PE, but they frequently have incidental findings that may require further evaluation. OBJECTIVE In order to examine common incidental findings and their possible clinical ramifications and required workup, we reviewed data from relevant studies in which chest CTs were performed and incidental findings discovered. DISCUSSION The most common incidental findings on chest CT are pulmonary nodules and lymph nodes. Nodules are significantly more commonly found in smokers and are also more likely to be malignant in smokers. The recently updated 2017 Fleischner Society recommendations provide guidance to clinicians in deciding which nodules should be further evaluated. Enlarged lymph nodes similarly represent potential malignancy and most will need further evaluation with positron emission tomography scans or by transbronchial needle aspiration. CONCLUSIONS Enlarged lymph nodes and pulmonary nodules are both common incidental findings on chest CT. Each represents the potential for malignancy, and under certain conditions requires additional workup and further evaluation. The majority will be benign, even in high-risk populations. However, because of the increasing prevalence of the chest CT and the frequency with which incidental findings will be seen, it is important that the emergency physician be aware of common features and recommended subsequent evaluation.

Shadowing emergency medicine residents by medical education specialists to provide feedback on non-medical knowledge-based ACGME sub-competencies

Objective Non-medical knowledge-based sub-competencies (multitasking, professionalism, accountability, patient-centered communication, and team management) are challenging for a supervising emergency medicine (EM) physician to evaluate in real-time on shift while also managing a busy emergency department (ED). This study examines residents’ perceptions of having a medical education specialist shadow and evaluate their nonmedical knowledge skills. Methods Medical education specialists shadowed postgraduate year 1 and postgraduate year 2 EM residents during an ED shift once per academic year. In an attempt to increase meaningful feedback to the residents, these specialists evaluated resident performance in selected non-medical knowledge-based Accreditation Council of Graduate Medical Education (ACGME) sub-competencies and provided residents with direct, real-time feedback, followed by a written evaluation sent via email. Evaluations provided specific references to examples of behaviors observed during the shift and connected these back to ACGME competencies and milestones. Results Twelve residents participated in this shadow experience (six post graduate year 1 and six postgraduate year 2). Two residents emailed the medical education specialists ahead of the scheduled shadow shift requesting specific feedback. When queried, five residents voluntarily requested their feedback to be included in their formal biannual review. Residents received milestone scores and narrative feedback on the non-medical knowledge-based ACGME sub-competencies and indicated the shadow experience and subsequent feedback were valuable. Conclusion Medical education specialists who observe residents over the course of an entire shift and evaluate non-medical knowledge-based skills are perceived by EM residents to provide meaningful feedback and add valuable information for the biannual review process.

COMPARISON OF KNOWLEDGE, PERCEPTION, AND ATTITUDES OF CONCUSSION IN CONCUSSED VERSUS NON-­‐CONCUSSED YOUTH SOCCER PLAYERS

ABSTRACT Objectives: To examine if history of concussion is correlated with a difference in knowledge, attitude, and perception of concussive injuries in youth soccer players. Methods: A convenience sample of youth soccer athletes aged 14 to 18 years completed a survey assessing prior history of concussive injury, knowledge of concussive injury, self-reporting attitudes, and perception of the injury. The survey consists of 16 knowledge questions (eleven on a scale of 1–2, and five on a scale of 1–4) and 12 attitude questions (seven on a scale of 1–4, and five on a scale of 1–5). The primary outcomes are the total scores calculated by summing the standardized raw scores for all knowledge questions and attitude questions, respectively. Linear regression was used to estimate the mean difference in the primary outcomes between previously concussed and non-concussed athletes (calculated as previously concussed – non-concussed). Results: Surveys were obtained from 90 athletes, with 32 (36%) previously sustaining at least one concussion. Thirty-one out of these 32 concussions were diagnosed by a medical provider. On average, the mean total raw scores of all knowledge questions are 34.6 (82.2% of 42 possible points) and 33.7 (80.2% of 42 total points) for previously concussed and non-concussed athletes, respectively, and the mean total raw scores of all attitude questions are 38.7 (72.9% of 53 possible points) and 39.6 (74.7% of 53 possible points), respectively. Mean differences estimated from univariate linear regression in the standardized total scores of knowledge questions and attitude questions are 1.56(95% confidence interval: −1.52–4.65) and −1.23 (%95 confidence interval: −4.64–2.19), respectively. Adjusting for age and years of playing soccer gave similar results. Conclusion: Although we did not find significant differences between previously concussed and non-concussed athletes in either the knowledge or the attitude questions as measured by their total scores, this study showed a high level of awareness of concussion in youth soccer players, while still highlighting a need for education. Limited distinctions were made among subgroups of players, suggesting directions of future research in investigating the role that outside factors may have on knowledge and perception of concussion.
