Delayed vertebral artery dissection after mild trauma in a motor vehicle collision.

Vertebral artery dissection can be insidious and is a leading cause of stroke in young patients, second only behind cardioembolic events [1]. We present the case of a 42-year-old patient who presented to the emergency department with diaphoresis and a complaint of neck pain one month after a low speed motor vehicle collision. The patient was transferred to a stroke center where cerebral angiography showed severe vertebral artery stenosis with likelihood of dissection after a noncontrast CT was negative for hemorrhage. She was definitively treated with antiplatelet therapy and discharged to rehab. By reviewing the most recent literature, we better define this illness. Most commonly, patients with arterial dissection present with head or neck pain, stroke, and Horner syndrome. It is now thought that vertebral artery dissection is a multifactorial disease process where certain intrinsic factors are present in the setting of an exacerbating extrinsic factor such as a low speed car accident, direct trauma, heavy lifting, or a rotational sports injury. And while our patient was treated with antiplatelet therapy and intravascular intervention, vertebral artery dissection is rare and further research is required to better guide treatment as there is no definitive data showing superiority of either anticoagulation or antiplatelet pharmaceutics.

Feasibility of Health Literacy Tools for Older Patients in the Emergency Department.

INTRODUCTION: This study evaluates the feasibility of using a volunteer research associate (RA) to administer two separate health literacy assessment tools in the emergency department (ED), specifically in an older population of patients. The outcomes measured were administration time and interruptions. METHODS: Using a prospective, cross-sectional study with a convenience sample, adult patients over the age of 55 presenting between June-August 2018 to one urban, academic ED were evaluated by a volunteer RA using either the Newest Vital Sign (NVS) or the Short Assessment of Health Literacy (SAHL). All patients 55 years of age or older who consented to participate were included. We excluded from this study the following: patients with dementia or other disability involving reading, speech, or cognitive function, as noted in their medical record or by their attending physician; prisoners; and those subjectively deemed in extremis or too ill to participate by their attending physician. RESULTS: Health literacy was assessed in 202 patients using either the NVS or SAHL. Mean time of administration was 214.0 seconds for the NVS, and 206.8 for the SAHL. The maximum time of administration for the NVS was 563 seconds, compared to 607 seconds for the SAHL. We found that 95.2% of NVS and 93.9% of SAHL tests incurred no interruptions during administration. CONCLUSION: No significant difference was found between the length of time needed to administer the NVS or SAHL to older patients in the ED. Both tools averaged an administration time of around three to four minutes, and neither incurred regular interruptions to its administration by a volunteer RA. Further study is needed to assess validity of these tools in an ED setting.

Mistriaged Advanced Life Support Patients in a Two-Tiered, Suburban Emergency Medical Services System.

INTRODUCTION: Emergency medical services (EMS) systems exist to provide prehospital care in diverse environments throughout the world. Advanced Life Support (ALS) services can provide advanced care including 12-lead electrocardiogram (ECG), endotracheal intubation and parenteral medication administration. Basic Life Support (BLS) can provide basic care such as splinting, wound care and cardiopulmonary resuscitation. ALS can release patients to BLS for transport to the hospital, and this is an area of high risk. Our study examines patients who were triaged and admitted to a critical care location, including an intensive care unit (ICU), cardiac catheterization laboratory, or operating room (OR). METHODS: The analysis included data from 2007-2015 of all patients who were triaged. We evaluated demographics, admission diagnoses, and dispositions using descriptive statistics. Diagnoses were grouped into categories based on the system. RESULTS: We found that 372/17,639 (2%) of patients were mistriaged to BLS and admitted to a critical care location. The average age was 64. The most common diagnosis categories were neurological (24%), gastrointestinal (GI)/abdominal pain (15%), respiratory (12%), and cardiac (12%). CONCLUSION: It is uncommon for patients triaged from ALS to BLS to be admitted to an ICU, catheterization lab or OR, with a rate of 2%. Neurological, GI, respiratory, and cardiac diagnoses were the most frequent categories of patient complaints that were mistriaged. This study should lead to further studies to examine this patient population.

Spontaneous Necrotizing Fasciitis.

Necrotizing soft tissue infections typically begin with direct inoculation of bacteria into the subcutaneous tissues. Here, we present a case with no such exposure, but with severe necrotizing fasciitis. We present a middle-aged man presented to the emergency department for a presumed allergic reaction after having initially sought care twice at an urgent care facility. The patient had swelling, but no tenderness of his right lateral chest and flank. Subsequent imaging showed extensive fluid in the fascial planes of the right chest wall requiring surgical debridement. Necrotizing fasciitis that is not treated with surgical debridement carries a mortality rate approaching 100%. This case highlights a potential atypical presentation as well as highlights the fact that the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score lacks sensitivity to rule out a necrotizing soft tissue infection, requiring surgical debridement for diagnosis.

Emergent Complications of Rheumatoid Arthritis.

BACKGROUND: Rheumatoid arthritis (RA) is an autoimmune disease resulting in polyarthritis and systemic effects that may result in morbidity and mortality. OBJECTIVE: This review provides the emergency physician with an updated analysis of acute complications seen with RA, as well as an evidence-based approach to the management of these complications. DISCUSSION: While the joint characteristics of RA are commonly recognized, the extra-articular manifestations may be overlooked. Of most concern to the emergency clinician is the involvement of the airway, cardiovascular, and pulmonary systems; however, RA can affect all organ systems. In addition, complications can arise from the specific therapies used to treat RA. Certain patient populations can have atypical presentations of the disease or may have an exaggerated response to the medications. An understanding of the involvement of these organ systems and complications can direct physicians to a broader differential that can identify disease processes that may have otherwise gone unnoticed. It is not necessarily the role of the clinician to diagnose RA in its earliest phases or initiate long-term immunosuppressive therapy from the emergency department; however, detection of some of the disease's characteristics can lead to earlier referral to specialists to begin therapy and potentially avoid life-threatening complications. If those problems are encountered in the emergency department, this review aims to provide insight into management of those conditions. CONCLUSIONS: Prompt recognition of the acute complications of RA is crucial to treat these conditions. This review investigates these issues in a succinct manner for emergency clinicians.

EMS providers do not use FOAM for education.

BACKGROUND: Free open access to medical education (FOAM, #FOAM) is the free availability of educational materials on various medicine topics. We hope to evaluate the use of social media and FOAM by emergency medical services (EMS) providers. METHODS: We designed an online survey distributed to EMS providers with questions about demographics and social media/FOAM use by providers. The survey was sent to the American College of Emergency Physicians (ACEP) EMS Listserv of medical directors and was asked to be distributed to their respective agencies. The survey was designed to inquire about the providers' knowledge of FOAM and social media and their use of the above for EMS education. RESULTS: There were 169 respondents out of a total of 523 providers yielding a response rate of 32.3%. Fifty-three percent of respondents are paramedics, 37% are EMT-Basic trained, and the remainder (16%) were "other." The minority (20%) of respondents had heard of FOAM. However, 54% of respondents had heard of "free medical education online" regarding pertinent topics. Of the total respondents who used social media for education, 31% used Facebook and 23% used blogs and podcasts as resources for online education. Only 4% of respondents stated they produced FOAM content. Seventy-six percent of respondents said they were "interested" or "very interested" in using FOAM for medical education. If FOAM provided continuing medical education (CME), 83% of respondents would be interested in using it. CONCLUSION: Social media is not used frequently by EMS providers for the purposes of FOAM. There is interest within EMS providers to use FOAM for education, even if CME was not provided. FOAM can provide a novel area of education for EMS.

Procedure rates performed by emergency medicine residents: a retrospective review.

BACKGROUND: The purpose of our study is to investigate rates of individual procedures performed by residents in our emergency medicine (EM) residency program. Different programs expose residents to different training environments. Our hypothesis is that ultrasound examinations are the most commonly performed procedure in our residency. METHODS: The study took place in an academic level I trauma center with multiple residency and fellowship programs including surgery, surgical critical care, trauma, medicine, pulmonary/critical care, anesthesiology and others. Also, the hospital provides a large emergency medical services program providing basic and advanced life support and critical care transport, which is capable of performing rapid sequence intubation. Each EM residency class, except for the first 2 months of the inaugural class, used New Innovations to log procedures. New Innovations is an online database for tracking residency requirements, such as procedures and hours. For the first 3 months, procedures were logged by hand on a log sheet. In addition, our department has a wireless electronic system (Qpath) for recording and logging ultrasound images. These logs were reviewed retrospectively without any patient identifiers. Actual procedures and simulation procedures were combined for analysis as they were only logged separately halfway through the study period. Procedures were summed and the average procedure rate per resident per year was calculated. RESULTS: In total, 66 full resident years were analyzed. Overall, ultrasound was the most commonly performed procedure, with each resident performing 125 ultrasounds per year. Removing "resuscitations," the second most common was endotracheal intubation, performed 28.91 times per year, and third most was laceration repair, which was performed 17.39 times per year. Our lowest performed procedure was thoracentesis, which was performed on average 0.11 times per resident per year. CONCLUSIONS: Residents performed a variety of procedures each year. Ultrasound examinations were the most frequent procedure performed. The number of ultrasound procedures performed may reflect the changing training landscape and influence future Accreditation Council of Graduate Medical Education requirements.

EMS Dispatches during Hurricanes Irene and Sandy in New Jersey.

BACKGROUND: Hurricanes Irene and Sandy heavily impacted New Jersey. Investigating EMS dispatch trends during these storms may allow us to prepare for future disasters. OBJECTIVES: Our objectives to characterize the types of EMS dispatches immediately before, during, and after landfall compared to a control period. METHODS: This retrospective study was conducted at a large EMS dispatch center that provides first responders, Basic Life Support (BLS), Advanced Life Support (ALS), and critical care transport services to an area with approximately 20 receiving hospitals including a Level I Trauma Center. At peak staffing, there are 8-10 ALS vehicles, 25 BLS vehicles, and 3 critical care transport vehicles deployed. We included of the day of landfall and seven days before and after. We compared dispatch data to a control period in 2010 that mirrored Hurricane Sandy the dates of. Descriptive statistics and two way ANOVA were used to assess dispatch, gender and age differences. RESULTS: We found Hurricane Sandy dispatches peaked 2 days after landfall. Both ALS and BLS had an increase in age in the post-Sandy period compared to the pre-Sandy (ALS 58.5 to 64.2, p = 0.005, ANOVA p = 0.078; BLS 47.4 to 56.3, p < 0.001, ANOVA p = 0.001). There were 17 "hurricane related" (loss of power related issues, oxygen supply depleted, evacuation) and 15 carbon monoxide dispatches in the post-Sandy period and none in the others, including peri-Irene. The average age of cardiac arrest dispatches was lower in the post-Irene group compared to pre-Irene (74.3 to 47.8, p = 0.023). There were no critical care requests before or after Hurricane Sandy, but there were 14 around Hurricane Irene and 10 surrounding the control period. CONCLUSIONS: Dispatch data can inform natural disaster planning. Education efforts can focus on geriatric patients, as well as resource distribution planning for an increase in geriatric populations. However, pattern variability between storms shows further study is needed to clarify exactly which resources should be utilized in order to maintain an ideal response to a natural disaster.

Spontaneous renal artery dissection presenting as an aortic dissection: a case report.

BACKGROUND: Renal artery dissection is a condition that has been associated with traumatic injuries and connective tissue disorders. It has been managed in the past by multiple methods because there is no standard treatment, including vascular intervention with angioplasty and stenting, anticoagulation/antiplatelet therapy, and hypertension management. CASE PRESENTATION: We present a case of a spontaneous renal artery dissection in a 55-year-old white man with no traditional risk factors who presented twice to our emergency department in a 2-day period with different symptoms; on his first presentation he presented with symptoms consistent with renal colic and on the second visit he presented with symptoms consistent with aortic dissection. CONCLUSIONS: Our patient was treated with endovascular stent placement by interventional radiology, heparin infusion, and admission to our medical intensive care unit. Our review here highlights the varied management of this diagnosis for which there is no standard treatment and decisions are made in conjunction with consultants.

Hand Washing Practices Among Emergency Medical Services Providers.

INTRODUCTION: Hand hygiene is an important component of infection control efforts. Our primary and secondary goals were to determine the reported rates of hand washing and stethoscope cleaning in emergency medical services (EMS) workers, respectively. METHODS: We designed a survey about hand hygiene practices. The survey was distributed to various national EMS organizations through e-mail. Descriptive statistics were calculated for survey items (responses on a Likert scale) and subpopulations of survey respondents to identify relationships between variables. We used analysis of variance to test differences in means between the subgroups. RESULTS: There were 1,494 responses. Overall, reported hand hygiene practices were poor among pre-hospital providers in all clinical situations. Women reported that they washed their hands more frequently than men overall, although the differences were unlikely to be clinically significant. Hygiene after invasive procedures was reported to be poor. The presence of available hand sanitizer in the ambulance did not improve reported hygiene rates but improved reported rates of cleaning the stethoscope (absolute difference 0.4, p=0.0003). Providers who brought their own sanitizer were more likely to clean their hands. CONCLUSION: Reported hand hygiene is poor amongst pre-hospital providers. There is a need for future intervention to improve reported performance in pre-hospital provider hand washing.

Intubation of the Neurologically Injured Patient.

BACKGROUND: Intubation of the neurologically injured patient is a critical procedure that must be done in a manner to prevent further neurologic injury. Although many different medications and techniques have been used to meet specific needs, there is little to no evidence to support many claims. OBJECTIVE: To review the literature regarding important topics relating to intubating patients with neurologic injury. DISCUSSION: Airway management requires ideal preoxygenation and airway maneuvers to minimize manipulation of the larynx and to maximize first-pass success. There is no evidence that lidocaine pretreatment decreases intracerebral pressure (ICP). Fentanyl can be used to help blunt the hemodynamic response to intubation. Esmolol is another medication that can blunt the hemodynamic response. Ketamine can be used and is possibly the ideal agent, having a neutral hemodynamic profile. A prefasciculation dose for neuromuscular blockade has not been shown to have any effect on ICP. CONCLUSIONS: Ideal intubation conditions should be obtained through the use of airway manipulation techniques and appropriate medication choice for rapid sequence intubation in patients who are neurologically injured.

Rapid Extrication versus the Kendrick Extrication Device (KED): Comparison of Techniques Used After Motor Vehicle Collisions.

INTRODUCTION: The goal of this study was to compare application of the Kendrick Extrication Device (KED) versus rapid extrication (RE) by emergency medical service personnel. Our primary endpoints were movement of head, time to extrication and patient comfort by a visual analogue scale. METHODS: We used 23 subjects in two scenarios for this study. The emergency medical services (EMS) providers were composed of one basic emergency medical technician (EMT), one advanced EMT. Each subject underwent two scenarios, one using RE and the other using extrication involving a commercial KED. RESULTS: Time was significantly shorter using rapid extraction for all patients. Angles of head turning were all significantly larger when using RE. Weight marginally modified the effect of KED versus RE on the "angle to right after patient moved to backboard (p= 0.029) and on subjective movement on patient questionnaire (p=0.011). No statistical differences were noted on patient discomfort or pain. CONCLUSION: This is a small experiment that showed decreased patient neck movement using a KED versus RE but resulted in increased patient movement in obese patients. Further studies are needed to determine if the KED improves any meaningful patient outcomes in the era of increased evidence-based medicine in emergency medical services.
