Wilderness Medical Society practice guidelines for the prevention and treatment of lightning injuries: 2014 update.

To provide guidance to clinicians about best practices, the Wilderness Medical Society (WMS) convened an expert panel to develop evidence-based guidelines for the treatment and prevention of lightning injuries. These guidelines include a review of the epidemiology of lightning and recommendations for the prevention of lightning strikes, along with treatment recommendations organized by organ system. Recommendations are graded on the basis of the quality of supporting evidence according to criteria put forth by the American College of Chest Physicians. This is an updated version of the original WMS Practice Guidelines for Prevention and Treatment of Lightning Injuries published in Wilderness & Environmental Medicine 2012;23(3):260-269.

Rearranging the furniture: A blueprint for reappropriating fixed resources to create an emergency department resuscitative care unit.

Emergency department (ED) care teams face challenges in providing timely, high-quality care to critically ill patients because of competing patient care priorities and a multitude of system strains, including patient boarding. Patients who are boarding in the ED experience increased morbidity and mortality, and this is particularly true for those who are critically ill. Geography-based models for critical care delivery in the ED range from resuscitation bays to full-fledged ED intensive care units. Studies have shown that such models can improve patient survival without affecting cost. Here, we describe how we reappropriated limited fixed resources to create a critical care resuscitation unit in a busy, urban, academic ED. Our objective is to provide a blueprint for similar models, paying particular attention to operations, clinical care, education, and financial stability.

A National Study of Emergency Thoracotomy for Trauma.

INTRODUCTION: The role of resuscitative thoracotomy in the emergency department (ED) for patients that have suffered severe thoracoabdominal trauma has been the subject of much debate. Most studies that characterize emergency thoracotomy are from urban, academic, and trauma centers. We sought to describe patient and hospital characteristics of a nationally representative sample of ED thoracotomy (EDT). METHODS: The health-care cost and utilization project 2013 National ED Sample (NEDS) and the 2013 National Inpatient Sample (NIS) maintained by the agency for health-care research and quality were used to generate a nationally representative estimate of resuscitative thoracotomies performed in the ED. We obtained patient demographics and clinical characteristics and compared the descriptive statistics of the two datasets. RESULTS: The NEDS dataset identified 124 unsuccessful EDTs, whereas the NIS dataset identified 77 admissions for thoracotomy. When weighted to create a national estimate, these represent 952 emergency thoracotomies performed in the US in 2013. Most were male (82.5% and 88.2% in NEDS and NIS, respectively). In addition, 32.9% and 36.4% in NEDS and NIS, respectively, were between the ages of 20 and 29. The majority of thoracotomies were performed at metropolitan teaching hospitals (64.2% and 75.3%, NEDS and NIS, respectively). The mean total ED charges for patients who had an unsuccessful thoracotomy were $32,664 and the mean total inpatient charges were $141,215. CONCLUSION: Nearly 1000 thoracotomies are performed annually on the day of presentation to U. S. hospitals. Although emergency thoracotomy for trauma is an infrequently performed procedure, it almost always occurs at an urban, high volume, and level I or level II trauma centers.

Hollow viscus injury.

BACKGROUND: Hollow viscus injuries are uncommon and occur in approximately 1% of all blunt trauma patients. DISCUSSION: These injuries are often not suspected and are difficult to diagnosis. Morbidity and mortality are high, and a negative abdominal computed tomography is not sufficient to rule out these injuries in certain clinical scenarios. CONCLUSION: Using a case-based approach, the epidemiology and diagnostic pathways to manage hollow viscus injuries are reviewed.

Ocular infection and inflammation.

Managing the inflamed or infected eye in the emergency setting presents a diagnostic and therapeutic challenge to the emergency physician; the causes and prognoses range from benign, self-limited illness to organ-threatening pathology. A careful history, with attention to comorbid illnesses and time course, is paramount, as is knowledge of the complete ophthalmologic examination. Much of the organ morbidity is ameliorated with prompt therapy in the emergency department and by initiating ophthalmologic consultation. In this article, the authors discuss the diagnosis and treatment of several types of eye infection, including conjunctivitis, episcleritis, keratitis, uveitis, hordeolum and chalazion, dacryocystitis, and cellulitis.

Using Rapid Improvement Events for Disaster After-Action Reviews: Experience in a Hospital Information Technology Outage and Response.

The use of after-action reviews (AARs) following major emergency events, such as a disaster, is common and mandated for hospitals and similar organizations. There is a recurrent challenge of identified problems not being resolved and repeated in subsequent events. A process improvement technique called a rapid improvement event (RIE) was used to conduct an AAR following a complete information technology (IT) outage at a large urban hospital. Using RIE methodology to conduct the AAR allowed for the rapid development and implementation of major process improvements to prepare for future IT downtime events. Thus, process improvement methodology, particularly the RIE, is suited for conducting AARs following disasters and holds promise for improving outcomes in emergency management.

Emergency Department Attending Physician Variation in Opioid Prescribing in Low Acuity Back Pain.

INTRODUCTION: Despite treatment guidelines suggesting alternatives, as well as evidence of a lack of benefit and evidence of poor long-term outcomes, opioid analgesics are commonly prescribed for back pain from the emergency department (ED). Variability in opioid prescribing suggests a lack of consensus and an opportunity to standardize and improve care. We evaluated the variation in attending emergency physician (EP) opioid prescribing for patients with uncomplicated, low acuity back pain (LABP). METHODS: This retrospective study evaluated the provider-specific proportion of LABP patients discharged from an urban academic ED over a seven-month period with a prescription for opioids. LABP was strictly defined as (1) back pain chief complaint, (2) discharged from ED with no interventions, and (3) predefined discharge diagnosis of back pain. We excluded providers if they had less than 25 LABP patients in the study period. The primary outcome was the physician-specific proportion of LABP patients discharged with an opioid analgesic prescription. We performed a descriptive analysis and then risk standardized prescribing proportion by adjusting for patient and clinical characteristics using hierarchical logistic regression. RESULTS: During the seven-month study period, 23 EPs treated and discharged at least 25 LABP patients and were included. Eight (34.8%) were female, and six (26.1%) were junior attendings (≤ 5 years after residency graduation). There were 943 LABP patients included in the analysis. Provider-specific proportions ranged from 3.7% to 88.1% (mean 58.4% [SD +/- 22.2]), and we found a 22-fold variation in prescribing proportions. There was a six-fold variation in the adjusted, risk-standardized prescribing proportion with a range from 12.0% to 78.2% [mean 50.4% (SD +/-16.4)]. CONCLUSION: We found large variability in opioid prescribing practices for LABP that persisted after adjustment for patient and clinical characteristics. Our findings support the need to further standardize and improve adherence to treatment guidelines and evidence suggesting alternatives to opioids.

Eye tracking detects disconjugate eye movements associated with structural traumatic brain injury and concussion.

Disconjugate eye movements have been associated with traumatic brain injury since ancient times. Ocular motility dysfunction may be present in up to 90% of patients with concussion or blast injury. We developed an algorithm for eye tracking in which the Cartesian coordinates of the right and left pupils are tracked over 200 sec and compared to each other as a subject watches a short film clip moving inside an aperture on a computer screen. We prospectively eye tracked 64 normal healthy noninjured control subjects and compared findings to 75 trauma subjects with either a positive head computed tomography (CT) scan (n=13), negative head CT (n=39), or nonhead injury (n=23) to determine whether eye tracking would reveal the disconjugate gaze associated with both structural brain injury and concussion. Tracking metrics were then correlated to the clinical concussion measure Sport Concussion Assessment Tool 3 (SCAT3) in trauma patients. Five out of five measures of horizontal disconjugacy were increased in positive and negative head CT patients relative to noninjured control subjects. Only one of five vertical disconjugacy measures was significantly increased in brain-injured patients relative to controls. Linear regression analysis of all 75 trauma patients demonstrated that three metrics for horizontal disconjugacy negatively correlated with SCAT3 symptom severity score and positively correlated with total Standardized Assessment of Concussion score. Abnormal eye-tracking metrics improved over time toward baseline in brain-injured subjects observed in follow-up. Eye tracking may help quantify the severity of ocular motility disruption associated with concussion and structural brain injury.

Rebuilding Emergency Care After Hurricane Sandy.

A freestanding, 911-receiving emergency department was implemented at Bellevue Hospital Center during the recovery efforts after Hurricane Sandy to compensate for the increased volume experienced at nearby hospitals. Because inpatient services at several hospitals remained closed for months, emergency volume increased significantly. Thus, in collaboration with the New York State Department of Health and other partners, the Health and Hospitals Corporation and Bellevue Hospital Center opened a freestanding emergency department without on-site inpatient care. The successful operation of this facility hinged on key partnerships with emergency medical services and nearby hospitals. Also essential was the establishment of an emergency critical care ward and a system to monitor emergency department utilization at affected hospitals. The results of this experience, we believe, can provide a model for future efforts to rebuild emergency care capacity after a natural disaster such as Hurricane Sandy.

The (f)utility of flexion-extension C-spine films in the setting of trauma.

BACKGROUND: Flexion-extension radiographs are often used to assess for removal of the cervical collar in the setting of trauma. The objective of this study was to evaluate their adequacy. We hypothesized that a significant proportion is inadequate. METHODS: This was a retrospective review of C-spine clearance at a level 1 trauma center. A trauma-trained radiologist interpreted all flexion-extension radiographs for adequacy. Studies performed within 7 days of injury were considered acute. RESULTS: Three hundred fifty-five flexion-extension radiographs were examined. Ninety-five percent% of these studies were inadequate (51% because of the inability to visualize the top of T1, whereas 44% had less than 30° of angulation from neutral). Two hundred ten studies were performed acutely; of these, 97% were inadequate. When performed 7 days or longer from injury, 91% were inadequate. CONCLUSIONS: Injury to the C-spine may harbor significant consequences; therefore, its proper evaluation is critical. The majority of flexion-extension films are inadequate. As such, they should not be included in the algorithm for removal of the cervical collar. If used, adequacy must be verified and supplemental radiographic studies obtained as indicated.

Evaluation of the psychiatric patient.

Patients presenting to the emergency department (ED) with behavioral disturbances account for approximately 6% of all ED visits. Emergency physicians are often responsible for the initial assessment of these patients' psychiatric complaints, which might include homicidal and suicidal behavior and acute psychosis. The emergency physician might be asked to provide medical clearance before transfer to definitive psychiatric care. The purpose of the medical screening is to identify medical conditions that might be causing or contributing to the psychiatric emergency or that might be dangerous or inappropriate to treat in a psychiatric facility. Appropriate treatment in the ED is essential to avoid morbidity and mortality resulting from misdiagnosis of medical conditions as psychiatric illnesses and from mismanagement of psychiatric illnesses.
