Patients Prefer Boarding in Inpatient Hallways: Correlation with the National Emergency Department Overcrowding Score

Objective. The boarding of patients in Emergency Department (ED) hallways when no inpatient beds are available is a major cause of ED crowding. One solution is to board admitted patients in an inpatient rather than ED hallway. We surveyed patients to determine their preference and correlated their responses to real-time National Emergency Department Overcrowding Score (NEDOCS). Methods. This was a survey of admitted patients in the ED of an urban university level I trauma center serving a community of 5 million about their personal preferences regarding boarding. Real-time NEDOCS was calculated at the time each survey was conducted. Results. 99 total surveys were completed during October 2010, 42 (42%) patients preferred to be boarded in an inpatient hallway, 33 (33%) preferred the ED hallway, and 24 (24%) had no preference. Mean (±SD) NEDOCS (range 0–200) was 136 ± 46 for patients preferring inpatient boarding, 112 ± 39 for ED boarding, and 119 ± 43 without preference. Male patients preferred inpatient hallway boarding significantly more than females. Preference for inpatient boarding was associated with a significantly higher NEDOCS. Conclusions. In this survey study, patients prefer inpatient hallway boarding when the hospital is at or above capacity. Males prefer inpatient hallway boarding more than females. The preference for inpatient hallway boarding increases as the ED becomes more crowded

Interobserver Agreement in the Clinical Assessment of Children With Blunt Abdominal Trauma

Objectives The objective was to determine the interobserver agreement of historical and physical examination findings assessed during the emergency department (ED) evaluation of children with blunt abdominal trauma. Methods This was a planned substudy of a multicenter, prospective cohort study of children younger than 18 years of age evaluated for blunt abdominal trauma. Patients were excluded if injury occurred more than 24 hours prior to evaluation or if computed tomography (CT) imaging was obtained at another hospital prior to transfer to a study site. Two clinicians independently recorded their clinical assessments of a convenience sample of patients onto data collection forms within 60 minutes of each other and prior to CT imaging (if obtained) or knowledge of laboratory results. The authors categorized variables as either subjective symptoms (i.e., patient history) or objective findings (i.e., physical examination). For each variable recorded by the two observers, the agreement beyond that expected by chance was estimated, using the kappa (κ) statistic for categorical variables and weighted κ for ordinal variables. Variables with 95% lower confidence limits (LCLs) κ ≥ 0.4 (moderate agreement or better) were considered to have acceptable agreement. Results A total of 632 pairs of physician observations were obtained on 23 candidate variables. Acceptable agreement was achieved in 16 (70%) of the 23 variables tested. For six subjective symptoms, κ ranged from 0.48 (complaint of shortness of breath) to 0.90 (mechanism of injury), and only the complaint of shortness of breath had a 95% LCL κ < 0.4. For the 17 objective findings, κ ranged from –0.01 (pelvis instability) to 0.82 (seat belt sign present). The 95% LCL for κ was <0.4 for flank tenderness, abnormal chest auscultation, suspicion of alcohol or drug intoxication, pelvis instability, absence of bowel sounds, and peritoneal irritation. Conclusions Observers can achieve at least acceptable agreement on the majority of historical and physical examination variables in children with blunt abdominal trauma evaluated in the ED. Those variables are candidates for consideration for development of a clinical prediction rule for intra‐abdominal injury in children with blunt trauma. Resumen Concordancia Interobservador en la Valoración Clínica de los Niños con Traumatismo Abdominal Cerrado Objetivos Determinar la concordancia interobservador de los hallazgos de la historia clínica y la exploración física obtenidos durante la valoración de los niños con traumatismo abdominal de alta energía en el servicio de urgencias (SU). Metodología Se diseñó un subestudio de un estudio de cohorte prospectivo y multicéntrico de niños de 18 años o menos evaluados por traumatismo abdominal cerrado. Se excluyeron los pacientes si el traumatismo había ocurrido más de 24 horas antes de la primera valoración, o si las imágenes de la tomografía computarizada (TC) se obtuvieron en otro hospital previamente a trasladarse al lugar del estudio. Dos clínicos recogieron de forma independiente su valoración clínica en un formulario de datos, de una muestra de conveniencia de pacientes, en los primeros 60 minutos, y previamente a las imágenes de la TC (si ésta se realizó) o al conocimiento de los resultados del laboratorio. Se clasificaron las variables como síntomas subjetivos (ej.: historia del paciente) o hallazgos objetivos (ej.: exploración física). Para cada variable recogida por los dos observadores, se estimó la concordancia más allá de la esperada por el azar usando el índice kappa (κ) para las variables categóricas y índice κ ponderado para las variables ordinales. Se consideró que existía una concordancia aceptable para las variables con una κ ≥ 0,4 (concordancia moderada o buena) en el límite inferior del intervalo de confianza del 95% (IC 95%). Resultados Se obtuvieron 632 pares de observaciones clínicas en 23 variables candidatas. Se alcanzó la concordancia aceptable en 16 (70%) de ellas. Para los seis síntomas subjetivos, el rango de κ fue de 0,48 (queja de dificultad respiratoria) a 0,90 (mecanismo de la lesión), y sólo la queja de dificultad respiratoria tuvo una κ < 0,4 en el límite inferior del IC 95%. Para los 17 hallazgos objetivos, el rango de κ fue desde ‐0,01 (inestabilidad pelvis) a 0,82 (presencia del signo del cinturón de seguridad). El dolor en el flanco, la auscultación torácica alterada, la sospecha de intoxicación por alcohol o tóxicos, la inestabilidad de pelvis, la ausencia de ruidos intestinales y la irritación peritoneal tuvieron una κ < 0,4 en el límite inferior del IC 95%. Conclusiones Los observadores pueden alcanzar al menos una concordancia aceptable en la mayoría de las variables de la historia clínica y la exploración física en los niños con traumatismo abdominal cerrado evaluado en el SU. Estas variables son candidatas para considerarse en el desarrollo de una regla de predicción clínica para la lesión intrabdominal en los niños con traumatismo de cerrado.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/98339/1/acem12132.pd

Occult Pneumothoraces in Children With Blunt Torso Trauma

Objectives Plain chest x‐ray (CXR) is often the initial screening test to identify pneumothoraces in trauma patients. Computed tomography (CT) scans can identify pneumothoraces not seen on CXR (“occult pneumothoraces”), but the clinical importance of these radiographically occult pneumothoraces in children is not well understood. The objectives of this study were to determine the proportion of occult pneumothoraces in injured children and the rate of treatment with tube thoracostomy among these children. Methods This was a planned substudy from a large prospective multicenter observational cohort study of children younger than 18 years old evaluated in emergency departments (EDs) in the Pediatric Emergency Care Applied Research Network (PECARN) for blunt torso trauma from May 2007 to January 2010. Children with CXRs as part of their trauma evaluations were included for analysis. The faculty radiologist interpretations of the CXRs and any subsequent imaging studies, including CT scans, were reviewed for the absence or presence of pneumothoraces. An “occult pneumothorax” was defined as a pneumothorax that was not identified on CXR, but was subsequently demonstrated on cervical, chest, or abdominal CT scan. Rates of pneumothoraces and placement of tube thoracostomies and rate differences with 95% confidence intervals (CIs) were calculated. Results Of 12,044 enrolled in the parent study, 8,020 (67%) children (median age = 11.3 years, interquartile range [IQR] = 5.3 to 15.2 years) underwent CXRs in the ED, and these children make up the study population. Among these children, 4,276 had abdominal CT scans performed within 24 hours. A total of 372 of 8,020 children (4.6%; 95% CI = 4.2% to 5.1%) had pneumothoraces identified by CXR and/or CT. The CXRs visualized pneumothoraces in 148 patients (1.8%; 95% CI = 1.6% to 2.2%), including one false‐positive pneumothorax, which was identified on CXR, but was not demonstrated on CT. Occult pneumothoraces were present in 224 of 372 (60.2%; 95% CI = 55.0% to 65.2%) children with pneumothoraces. Tube thoracostomies were performed in 85 of 148 (57.4%; 95% CI = 49.0% to 65.5%) children with pneumothoraces on CXR and in 35 of 224 (15.6%; 95% CI = 11.1% to 21.1%) children with occult pneumothoraces (rate difference = –41.8%; 95% CI = –50.8 to –32.3%). Conclusions In pediatric patients with blunt torso trauma, pneumothoraces are uncommon, and most are not identified on the ED CXR. Nearly half of pneumothoraces, and most occult pneumothoraces, are managed without tube thoracostomy. Observation, including in children requiring endotracheal intubation, should be strongly considered during the initial management of children with occult pneumothoraces. Resumen Objetivos La radiografía de tórax simple (RXT) es a menudo la prueba de despistaje inicial para identificar los neumotórax en los pacientes con traumatismo. La tomografía computarizada (TC) puede identificar neumotórax no vistos en la RXT (“neumotórax ocultos”), aunque la importancia clínica de estos neumotórax radiográficamente ocultos en los niños no está muy estudiada. Los objetivos de este estudio fueron determinar la proporción de neumotórax ocultos en los niños accidentados y el porcentaje de tratamiento con tubo de toracostomía en estos niños. Metodología Subestudio diseñado a partir de un gran estudio observacional de cohorte prospectivo multicéntrico de niños menores de 18 años atendidos en los servicios de urgencias (SU) de la Pediatric Emergency Care Applied Research Network (PECARN) que habían sido evaluados por traumatismo torácico cerrado de mayo de 2007 a enero de 2010. Se incluyeron en el análisis los niños en los que la RXT fue parte de la evaluación inicial del traumatismo. Las interpretaciones del radiólogo de las RXT y de cualquier estudio de imagen posterior, incluyendo a TC, se revisaron para la ausencia o presencia de neumotórax. Se definió “neumotórax oculto” como un neumotórax que no fue identificado en la RXT pero que fue posteriormente visualizado en la TC abdominal, torócica o cervical. Se calcularon los porcentajes de neumotórax e inserción de tubo de toracostomía y las diferencias de sus porcentajes con los intervalos de confianza (IC) al 95%. Resultados De los 12.044 incluidos en el estudio principal, se llevo a cabo una RXT en el SU en 8.020 (67%) niños (mediana de edad 11,3 años, rango intercuartílico 5,3 a 15,2), que constituyeron la población de estudio. De estos niños, 4.276 tuvieron una TC realizada en las primeras 24 horas. En 372 de los 8.020 niños (4,6%; IC 95% = 4,2% a 5,1%) se identificó un neumotórax en la RXT y/o la TC. La RXT mostró neumotórax en 148 pacientes (1,8%; IC 95% = 1,6% a 2,2%), incluyendo un falso positivo de neumotórax, que fue identificado en la RXT pero que no fue demostrado en la TC. Los neumotórax ocultos estuvieron presentes en 224 de los 372 niños con neumotórax (60,2%; IC 95% = 55,0% a 65,2%). Se insertaron tubos de toracostomía en 85 de los 148 niños con neumotórax en la RXT (57,4%; IC 95% = 49,0% a 65,5%), y en 35 de los 224 niños con neumotórax oculto (15,6%; IC 95% = 11,1% a 21,1%; diferencia de porcentajes ‐41,8%; IC 95% = ‐50,8 a ‐32,3%). Conclusiones En los pacientes pediátricos con traumatismo torácico cerrado, los neumotórax son poco frecuentes, y la mayoría no son identificados en la RXT en el SU. Casi la mitad de los neumotórax, y la mayoría de los neumotórax ocultos son manejados sin tubo de toracostomía. La observación, incluyendo en los niños que requieren intubación endotraqueal, debería ser especialmente considerada durante el manejo inicial de los niños con neumotórax ocultos.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/106913/1/acem12344.pd

Expression of the Inherently Autoreactive Idiotope 9G4 on Autoantibodies to Citrullinated Peptides and on Rheumatoid Factors in Patients with Early and Established Rheumatoid Arthritis.

The pre-symptomatic stage of Rheumatoid arthritis (RA) is associated with pro-inflammatory cytokines and autoantibodies. High levels and epitope spread by Rheumatoid factors (RhF) and autoantibodies to citrullinated proteins signify progression towards disease expression. In established RA, the persistence of high autoantibody levels reflects production by both long-lived plasma cells and short-lived plasmablasts. Neither the relative contributions to pathogenesis by autoantibodies from either source, nor the factors responsible for deciding the fate of autoantigen specific 'parent' B-cells, is understood. Phenotypic markers identifying subsets of autoreactive B-cells are therefore of interest in understanding the origin and perpetuation of the autoimmune response in RA. One such phenotypic marker is the rat monoclonal antibody, 9G4, which recognises an idiotope on immunoglobuins derived from the inherently autoreactive VH-gene, VH4-34. We therefore investigated whether the 9G4 idiotope was expressed on autoantibodies in patients with RA

31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two

Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival

Association Between the Seat Belt Sign and Intra‐abdominal Injuries in Children With Blunt Torso Trauma in Motor Vehicle Collisions

Objectives The objective was to determine the association between the abdominal seat belt sign and intra‐abdominal injuries ( IAI s) in children presenting to emergency departments with blunt torso trauma after motor vehicle collisions ( MVC s). Methods This was a planned subgroup analysis of prospective data from a multicenter cohort study of children with blunt torso trauma after MVC s. Patient history and physical examination findings were documented before abdominal computed tomography ( CT ) or laparotomy. Seat belt sign was defined as a continuous area of erythema, ecchymosis, or abrasion across the abdomen secondary to a seat belt restraint. The relative risk ( RR ) of IAI with 95% confidence intervals ( CI s) was calculated for children with seat belt signs compared to those without. The risk of IAI in those patients with seat belt sign who were without abdominal pain or tenderness, and with Glasgow Coma Scale ( GCS ) scores of 14 or 15, was also calculated. Results A total of 3,740 children with seat belt sign documentation after blunt torso trauma in MVC s were enrolled; 585 (16%) had seat belt signs. Among the 1,864 children undergoing definitive abdominal testing ( CT , laparotomy/laparoscopy, or autopsy), IAI s were more common in patients with seat belt signs than those without (19% vs. 12%; RR  = 1.6, 95% CI  = 1.3 to 2.1). This difference was primarily due to a greater risk of gastrointestinal injuries (hollow viscous or associated mesentery) in those with seat belt signs (11% vs. 1%; RR  = 9.4, 95% CI  = 5.4 to 16.4). IAI was diagnosed in 11 of 194 patients (5.7%; 95% CI  = 2.9% to 9.9%) with seat belt signs who did not have initial complaints of abdominal pain or tenderness and had GCS scores of 14 or 15. Conclusions Patients with seat belt signs after MVC s are at greater risk of IAI than those without seat belt signs, predominately due to gastrointestinal injuries. Although IAI s are less common in alert patients with seat belt signs who do not have initial complaints of abdominal pain or tenderness, the risk of IAI is sufficient that additional evaluation such as observation, laboratory studies, and potentially abdominal CT scanning is generally necessary. Resumen Objetivos Determinar la asociación entre el signo del cinturón de seguridad ( SCS ) y las lesiones intra‐abdominales ( LIA ) en los niños atendidos en los servicios de urgencias por traumatismo torácico cerrado tras colisiones de vehículo de motor ( CVM ). Metodología Éste fue un análisis de subgrupo planificado de los datos prospectivos de un estudio de cohorte multicéntrico de niños con traumatismo torácico cerrado tras CVM . Se documentó la historia clínica y la exploración física del paciente antes de la tomografía computarizada ( TC ) abdominal o la laparotomía. El SCS se definió como un área continua de eritema, equimosis o abrasión a través del abdomen secundaria a la contención del cinturón de seguridad. Se calculó el riesgo relativo ( RR ) de LIA con los intervalos de confianza ( IC ) al 95% para los niños con SCS en comparación con aquéllos que no lo tenían. También se calculó el riesgo de LIA en aquellos pacientes con SCS que no tuvieron molestia o dolor abdominal con puntuaciones de 14 o 15 de la Escala de Coma de Glasgow ( ECG ). Resultados Se incluyeron 3.740 niños tras un traumatismo torácico cerrado en CVM ; 585 (16%) tuvieron SCS . Entre los 1.864 niños en los que se llevó a cabo un test diagnóstico abdominal definitivo ( TC , laparotomía/ laparoscopia, o autopsia), las LIA fueron más frecuentes en los pacientes con SCS que en aquéllos sin SCS (19% vs. 12%, RR  = 1,6; IC 95% = 1,3 a 2,1). Esta diferencia fue principalmente debida a un mayor riesgo de lesiones gastrointestinales (víscera hueca o asociadas al mesenterio) en aquéllos con SCS (11% vs. 1%, RR  = 9,4; IC 95% = 5,4 a 16,4). La LIA se diagnosticó en 11 de 194 pacientes (5,7%, IC 95% = 2,9% a 9,9%) con SCS que no tuvieron quejas iniciales de molestia o dolor abdominal y tuvieron puntuaciones de 14 o 15 en la ECG . Conclusiones Los pacientes con SCS tras una CVM tienen mayor riesgo de LIA que aquéllos sin SCS , debido fundamentalmente a lesiones gastrointestinales. Aunque las LIA son menos comunes en los pacientes con SCS que están alerta y que no tienen quejas iniciales de molestia o dolor abdominal, el riesgo de LIA es suficiente para que evaluaciones como la observación, las pruebas de laboratorio y potencialmente la TC abdominal sean generalmente necesarios.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/109632/1/acem12506.pd

Industry Relations With Emergency Medicine Graduate Medical Education Programs

A panel of physicians from the Society for Academic Emergency Medicine (SAEM) Graduate Medical Education (GME), Ethics, and Industry Relations Committees were asked by the SAEM Board of Directors to write a position paper on the relationship of emergency medicine (EM) GME with industry. Using multiple sources as references, the team derived a set of guidelines that all EM GME training programs can use when interacting with industry representatives. In addition, the team used a question–answer format to provide educators and residents with a practical approach to these interactions. The SAEM Board of Directors endorsed the guidelines in June 2009

Ethics Curriculum for Emergency Medicine Graduate Medical Education

Background Ethics education is an essential component of graduate medical education in emergency medicine. A sound understanding of principles of bioethics and a rational approach to ethical decision-making are imperative. Objective This article addresses ethics curriculum content, educational approaches, educational resources, and resident feedback and evaluation. Discussion Ethics curriculum content should include elements suggested by the Liaison Committee on Medical Education, Accreditation Council for Graduate Medical Education, and the Model of the Clinical Practice of Emergency Medicine. Essential ethics content includes ethical principles, the physician-patient relationship, patient autonomy, clinical issues, end-of-life decisions, justice, education in emergency medicine, research ethics, and professionalism. Conclusion The appropriate curriculum in ethics education in emergency medicine should include some of the content and educational approaches outlined in this article, although the optimal methods for meeting these educational goals may vary by institution

Variation in Specialists’ Reported Hospitalization Practices of Children Sustaining Blunt Abdominal Trauma

Introduction: Children with blunt abdominal trauma (BAT) are often hospitalized despite no intervention. We identified factors associated with emergency department (ED) disposition of children with BAT and differing computed tomography (CT) findings.Methods: We surveyed pediatric and general emergency physicians (EPs), pediatric and trauma surgeons regarding care of two hypothetical asymptomatic patients: a 9-year-old struck by a slow-moving car (Case 1) and an 11-month-old who fell 10 feet (Case 2). We presented various abdominal CT findings and asked physicians about disposition preferences. We evaluated predictors of patient discharge using multivariable regression analysis, adjusting for hospital and ED characteristics, and clinician experience. Pediatric EPs served as the reference group.Results: Of 2,003 eligible surveyed, 636 (32%) responded. For normal CTs, 99% would discharge in Case 1 and 88% in Case 2. Prominent specialty differences included: for trace intraperitoneal fluid (TIF), 68% would discharge in Case 1 and 57% in Case 2. Patients with TIF were less likely to be discharged by pediatric surgeons (Case 1: OR 0.52, 95% CI 0.32, 0.82; Case 2: OR 0.49, 95% CI 0.30, 0.79). Patients with renal contusions were less likely to be discharged by pediatric surgeons (Case 1: OR 0.55, 95% CI 0.32, 0.95) and more likely by general EPs (Case 1: OR 1.83, 95% CI 1.25, 2.69; Case 2: OR 2.37, 95% CI 1.14, 4.89).Conclusion: Substantial variation exists between specialties in reported hospitalization practices of asymptomatic children after abdominal trauma with minor CT findings. Better evidence is needed to guide disposition decisions. [West J Emerg Med. 2013;14(1):37-46.
