Atypical Presentation and Diagnosis of Multiple Myeloma: A Case Report.

Chronic neck pain is a common, seemingly benign condition that typically does not warrant an urgent workup, in contrast to acute onset neck pain. Vertebral artery dissection (VAD) is a relatively rare presentation of acute onset neck pain and often presents in the context of blunt trauma. Due to the risk of subsequent clot formation and stroke, patients who present with symptoms suggestive of VAD must be promptly screened, most often first with computed tomography angiography (CTA) followed by magnetic resonance imaging (MRI) or magnetic resonance angiography (MRA) for further evaluation. We present a case of a 69-year-old male with a history of chronic neck pain who was seen in the emergency department due to acute, severe neck pain with initial CTA imaging that suggested left VAD. However, follow-up MRI of his cervical spine identified that what seemed to be a left VAD was instead multiple myeloma. This case demonstrates the utility of using multiple imaging modalities, including CT, CTA, MRI, and MRA, in diagnosing an atypical presentation of multiple myeloma and the consequences of physician implicit biases that are often involved when treating patients with chronic pain.

Assessment of Emergency Medicine Resident Performance in a Pediatric In Situ Simulation Using Multi-Source Feedback.

Introduction Multi-source feedback (MSF) is an evaluation method mandated by the Accreditation Council for Graduate Medical Education (ACGME). The Queen's Simulation Assessment Tool (QSAT) has been validated as being able to distinguish between resident performances in a simulation setting. The QSAT has also been demonstrated to have excellent MSF agreement when used in an adult simulation performed in a simulation lab. Using the QSAT, this study sought to determine the degree of agreement of MSF in a single pediatric (Peds) simulation case conducted in situ in a Peds emergency department (ED). Methods This Institutional Review Board-approved study was conducted in a four-year emergency medicine residency. A Peds resuscitation case was developed with specific behavioral anchors on the QSAT, which uses a 1-5 scale in each of five categories: Primary Assessment, Diagnostic Actions, Therapeutic Actions, Communication, and Overall Assessment. Data was gathered from six participants for each simulation. The lead resident self-evaluated and received MSF from a junior peer resident, a fixed Peds ED nurse, a random ED nurse, and two faculty (one fixed, the other from a dyad). The agreement was calculated with intraclass correlation coefficients (ICC). Results The simulation was performed on 35 separate days over two academic years. A total of 106 MSF participants were enrolled. Enrollees included three faculty members, 35 team leaders, 34 peers, 33 ED registered nurses (RN), and one Peds RN; 50% of the enrollees were female (n=53). Mean QSAT scores ranged from 20.7 to 23.4. A fair agreement was demonstrated via ICC; there was no statistically significant difference between sources of MSF. Removing self-evaluation led to the highest ICC. ICC for any single or grouped non-faculty source of MSF was poor. Conclusion Using the QSAT, the findings from this single-site cohort suggest that faculty must be included in MSF. Self-evaluation appears to be of limited value in MSF with the QSAT. The degree of MSF agreement as gathered by the QSAT was lower in this cohort than previously reported for adult simulation cases performed in the simulation lab. This may be due to either the pediatric nature of the case, the location of the simulation, or both.

A Modified Delphi Study to Prioritize Content for a Simulation-based Pediatric Curriculum for Emergency Medicine Residency Training Programs.

OBJECTIVES: Pediatric training is an essential component of emergency medicine (EM) residency. The heterogeneity of pediatric experiences poses a significant challenge to training programs. A national simulation curriculum can assist in providing a standardized foundation of pediatric training experience to all EM trainees. Previously, a consensus-derived set of content for a pediatric curriculum for EM was published. This study aimed to prioritize that content to establish a pediatric simulation-based curriculum for all EM residency programs. METHODS: Seventy-three participants were recruited to participate in a three-round modified Delphi project from 10 stakeholder organizations. In round 1, participants ranked 275 content items from a published set of pediatric curricular items for EM residents into one of four categories: definitely must, probably should, possibly could, or should not be taught using simulation in all residency programs. Additionally, in round 1 participants were asked to contribute additional items. These items were then added to the survey in round 2. In round 2, participants were provided the ratings of the entire panel and asked to rerank the items. Round 3 involved participants dichotomously rating the items. RESULTS: A total of 73 participants participated and 98% completed all three rounds. Round 1 resulted in 61 items rated as definitely must, 72 as probably should, 56 as possibly could, 17 as should not, and 99 new items were suggested. Round 2 resulted in 52 items rated as definitely must, 91 as probably should, 120 as possibly could, and 42 as should not. Round 3 resulted in 56 items rated as definitely must be taught using simulation in all programs. CONCLUSIONS: The completed modified Delphi process developed a consensus on 56 pediatric items that definitely must be taught using simulation in all EM residency programs (20 resuscitation, nine nonresuscitation, and 26 skills). These data will serve as a targeted needs assessment to inform the development of a standard pediatric simulation curriculum for all EM residency programs.

Enterocolitis in a Child With Hirschsprung Disease.

Hirschsprung disease is a congenital abnormality that can be surgically corrected. However, Hirschsprung-associated enterocolitis can be a life-threatening sequela. Very little has been published in the emergency medicine literature about the risk of enterocolitis and shock in patients with a history of Hirschsprung disease. We describe the case of a 6-month-old male infant with a history of multiple surgeries for Hirschsprung disease who presented to the emergency department with a seemingly benign viral gastrointestinal illness. His stable condition led him to be discharged. However, 4 days later, he returned to the emergency department with severe diarrhea and was subsequently admitted to the pediatric intensive care unit for the management of enterocolitis and shock. With this case report, we aim to raise emergency physicians' awareness of the serious and possibly fatal complications of Hirschsprung disease. We argue that this single element of a patient's medical history can alter the management of seemingly simple viral gastrointestinal illnesses; rather than be discharged, such a patient requires surgical consultation and possibly admission for close monitoring and treatment.

Alternative Markers of Performance in Simulation: Where We Are and Where We Need To Go.

This article on alternative markers of performance in simulation is the product of a session held during the 2017 Academic Emergency Medicine Consensus Conference "Catalyzing System Change Through Health Care Simulation: Systems, Competency, and Outcomes." There is a dearth of research on the use of performance markers other than checklists, holistic ratings, and behaviorally anchored rating scales in the simulation environment. Through literature review, group discussion, and consultation with experts prior to the conference, the working group defined five topics for discussion: 1) establishing a working definition for alternative markers of performance, 2) defining goals for using alternative performance markers, 3) implications for measurement when using alternative markers, identifying practical concerns related to the use of alternative performance markers, and 5) identifying potential for alternative markers of performance to validate simulation scenarios. Five research propositions also emerged and are summarized.

Perceived Fall Risk and Functional Decline: Gender Differences in Patient's Willingness to Discuss Fall Risk, Fall History, or to Have a Home Safety Evaluation.

The CDC reports that among older adults, falls are the leading cause of injury-related death and rates of fall-related fractures among older women are twice those of men. We set out to 1) determine patient perceptions (analyzed by gender) about their perceived fall risk compared to their actual risk for functional decline and death and 2) to report their comfort level in discussing their fall history or a home safety plan with their provider. Elders who presented to the Emergency Department (ED†) were surveyed. The survey included demographics, the Falls Efficacy Scale (FES) and the Vulnerable Elders Survey (VES); both validated surveys measuring fall concern and functional decline. Females had higher FES scores (mean 12.3, SD 5.9) than males (mean 9.7, SD 5.9 p = .007) in the 146 surveys analyzed. Females were more likely to report an increased fear of falling, and almost three times more likely to have a VES score of 3 or greater than males (OR = 2.86, 95% CI: 1.17-7.00, p = .02). A strong correlation was observed between FES and VES scores (r = 0.80, p < .001). No difference in correlation was observed between males and females, p = .26. Participants (77 percent) reported they would be comfortable discussing their fall risk with a provider; there was no difference between genders (p = .57). In this study, irrespective of gender, there appears to be a high association between subjects' perceived fall risk and risk for functional decline and death. The majority of patients are likely willing to discuss their fall risk with their provider. These findings may suggest a meaningful opportunity for fall risk mitigation in this setting.

Mechanical falls: are patients willing to discuss their risk with a health care provider?

BACKGROUND: Falls in the elderly cause serious injury. OBJECTIVE: We aimed to determine subjects' comfort in discussing fall risk and home safety evaluations. METHODS: This prospective study surveyed a convenience sample of subjects (≥50 years old) in an emergency department (ED), health fair (HF), and family practice (FP). The survey included the Falls Efficacy Scale and Vulnerable Elders Survey-validated surveys measuring fall concern and functional decline. Other data-environmental living conditions, participant behaviors, fall frequency-were collected. The associations between perceived fall risk and participant characteristics were assessed using descriptive statistics and random-effects logistic regression. RESULTS: Participants (n = 416, 38% males, 62% females) had a mean age of 67.6 years; 35% were high fall risk. Previous year falls (p = 0.002), use of assistive device (p < 0.001), having at least one alcoholic drink/week (p = 0.043), and poor or fair perceived health status (p < 0.001) were associated with perceived fall risk. HF respondents were more willing than FP respondents to discuss falls (84.9% vs. 73.1%, p = 0.025). The difference was not significant between the HF and ED respondents (84.9% vs. 76.9, p = 0.11). HF subjects were more willing than FP to have a home safety inspection (68.9% vs. 45.9%, p < 0.001). The difference was not significant between the HF and ED respondents (68.9% vs 58.5, p = 0.09). CONCLUSIONS: Perceived and actual fall risks are highly associated. Most participants are willing to discuss their fall risk and a home safety evaluation. HF subjects were most willing to have these discussions; ED subjects were less willing than HF, but not significantly different from health fair participants. FP participants were significantly less willing to have these discussions than HF participants. This may suggest a meaningful opportunity for fall risk prevention in outpatient settings such as health fairs and the ED.

Injury due to mechanical falls: future directions in gender-specific surveillance, screening, and interventions in emergency department patients.

The Centers for Disease Control and Prevention report that among older adults (≥65 years), falls are the leading cause of injury-related death. Fall-related fractures among older women are more than twice as frequent as those for men. Gender-specific evidence-based fall prevention strategy and intervention studies show that improved patient-centered outcomes are elusive. There is a paucity of emergency medicine literature on the topic. As part of the 2014 Academic Emergency Medicine (AEM) consensus conference on "Gender-Specific Research in Emergency Care: Investigate, Understand, and Translate How Gender Affects Patient Outcomes," a breakout group convened to generate a research agenda on priority questions to be answered on this topic. The consensus-based priority research agenda is presented in this article.

Effect of coronary target lesion revascularization on late cardiac events after insertion of sirolimus-eluting or bare metal stents.

Restenosis is associated with acute myocardial infarction (MI) either at presentation or related to complications of target lesion revascularization (TLR). The cumulative late effect of TLR after drug-eluting or bare metal stent placement on cardiac death or MI is uncertain. Of the 1,057 patients with one native coronary lesion randomized to a sirolimus-eluting stent or bare metal stent in the Sirolimus-Eluting Stent in De Novo Native Coronary Lesions (SIRIUS) trial, the 983 who survived free of MI for the first 30 days were evaluated for the primary outcome of cardiac death or MI for 5 years. Patients with events occurring at or after TLR were assigned to TLR group. Cox proportional hazards regression analysis with TLR as a time-dependent variable and adjustment for baseline clinical and demographic covariates was used to assess the independent effect of TLR on the primary outcome. TLR occurred in 160 patients (16.3%) and was an independent predictor of the primary end point (hazard ratio 2.8, 95% confidence interval 1.7 to 4.5). This association was significant for sirolimus-eluting stents and bare metal stents. TLR was also associated with an increased risk of subsequent stent thrombosis and nontarget vessel revascularization. Intracoronary brachytherapy in the TLR group was associated with an increased risk of cardiac death or MI. In conclusion, restenosis requiring TLR was associated with an increased risk of cardiac death or MI occurring at TLR and during the subsequent 5 years.

Door-to-balloon times are reduced in ST-elevation myocardial infarction by emergency physician activation of the cardiac catheterisation laboratory and immediate patient transfer.

OBJECTIVES: To assess whether a collaborative interdepartmental pathway involving emergency department (ED) physicians activating the cardiac catheterisation laboratory (CCL) with immediate patient transfer to the CCL reduces door-to-balloon (DTB) times for patients with suspected ST-elevation myocardial infarction (STEMI). DESIGN, SETTING AND PARTICIPANTS: A quasi-experimental before-and-after observational study using a prospective database, supplemented by chart review, of consecutive patients transferred from the ED to the CCL for suspected STEMI, from January 2007 to October 2009, at Sir Charles Gairdner Hospital, an adult tertiary-care hospital, Western Australia. MAIN OUTCOMES MEASURES: Median DTB time and proportion of patients with DTB time of < 90 minutes. Secondary outcomes, based on analysis of predefined subgroups, included door-to-activation time, activation-to-balloon time and false-positive activations of the CCL. RESULTS: Two hundred and thirty-four patients underwent emergency coronary angiography for suspected STEMI, with 188 (80%) undergoing percutaneous coronary intervention (118 before and 70 after implementation of the new pathway). Following implementation of the new pathway, median DTB time reduced from 97 to 77 minutes (P < 0.001), median door-to-activation time from 28 to 15 minutes (P = 0.002) and median activation-to-balloon time from 66 to 53 minutes (P < 0.001). The proportion of patients with recommended DTB time of < 90 minutes increased from 41% to 77% (P < 0.001) with no change in false positive CCL activation rates (12% v 11%; P = 0.38). CONCLUSION: ED physician activation of CCL with immediate patient transfer is associated with highly significant improvements in DTB time without increased false positive rates.

Management of a renal artery aneurysm with coil embolization.

We describe a case of a 51-year-old female who was incidentally noted to have a renal artery aneurysm on computed tomography (CT). The aneurysm was not seen on an abdominal CT performed 4 years prior, so the patient underwent successful percutaneous coil embolization. The indications for repair of such aneurysms are unknown, and there are a myriad of surgical and percutaneous management options. Because of the increase in abdominal imaging, the incidence of renal artery aneurysms is likely to rise. We describe the case and review the literature surrounding the epidemiology, outcome and management of renal artery aneurysms.

Combining warfarin and antiplatelet therapy after coronary stenting in the Global Registry of Acute Coronary Events: is it safe and effective to use just one antiplatelet agent?

AIMS: To identify factors associated with the use of single or dual antiplatelet therapy in patients prescribed warfarin following coronary stenting and to investigate whether single (aspirin or thienopyridine) vs. dual antiplatelet therapy plus warfarin leads to an excess of adverse outcomes. METHODS AND RESULTS: We analysed data from 800 patients with an acute coronary syndrome who underwent coronary stenting (130 patients received a drug-eluting stent) and were discharged on warfarin and either dual (n = 580) or single (n = 220) antiplatelet therapy. The use of single antiplatelet therapy was more common in Europe than in the USA (34 vs. 17%, P < 0.001). There was no difference in major bleeding in hospital or in 6-month mortality or myocardial infarction. In the single antiplatelet group, the use of either aspirin or thienopyridine (clopidogrel or ticlopidine) in combination with warfarin resulted in similar outcomes. CONCLUSION: Use of single vs. dual antiplatelet therapy and warfarin following stenting is common. In this observational study, there was no difference in mortality or myocardial infarction at 6 months; however, larger trials are needed to assert any firm recommendations.
