COVID-19 Computed tomography patterns in renal replacement therapy patients / Padrões de tomografia computadorizada da COVID-19 em pacientes em terapia renal substitutiva

ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12-84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.

RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12-84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19.

Enfrentamiento inicial de las intoxicaciones por medicamentos orales en el servicio de urgencia / Initial management of toxic exposures to oral drugs in the emergency department

Las intoxicaciones en Chile siguen siendo un motivo importante de consulta en el servicio de urgencia (SU). Tanto intoxicaciones accidentales como intencionales constituyen una fuente de morbimortalidad y gasto de recursos monetarios no solo en Chile, si no que en todo el mundo. Debido a los múltiples compuestos que pueden producir una intoxicación grave, sigue siendo un desafío para el equipo de salud su enfrentamiento y manejo oportuno. Los médicos que tratan a estos pacientes deben ser sistemáticos y ordenados en su enfrentamiento, ya que la presentación clínica es variada y depende del agente ingerido, co-ingestas, si es aguda o crónica o concomitante con otras patologías (trauma, infecciones, etc.). El manejo está dirigido a las maniobras básicas de reanimación y soporte vital, prevención de absorción del tóxico y cuando corresponda, la administración del antídoto. La evaluación y tratamiento inicial serán abordados en esta revisión, temas específicos para diferentes drogas serán discutidos de forma separada. Objetivo: entregar las nociones básicas del enfrentamiento y manejo terapéutico inicial de un paciente intoxicado desde la perspectiva de la medicina de urgencias. Método: se realizó una revisión bibliográfica de la literatura científica, presentándose la evidencia actual del manejo e intervenciones terapéuticas utilizadas actualmente de un paciente intoxicado.

In Chile, poisonings are a frequent reason for emergency department visits. Accidental and intentional poisonings constitute an important source of worldwide morbidity, mortality and health care costs. Because of the heterogeneous presentations of poisonings, and the unknown exposure, it is always challenging for healthcare providers. Doctors who treat these patients must remember to be systematic and structured in their evaluation since the clinical presentation is not only determined by the exposure itself but also by co-ingestions, the time of presentation, whether the exposure is acute or chronic, and other concomitant health issues (trauma, hypothermia, comorbidities). The management focuses on basic resuscitation and life support, prevention of absorption of the toxin, and when appropriate, administering an antidote. Initial evaluation and treatment will be addressed in this review, and specific issues for different drugs will be discussed elsewhere. Objective: to describe the basic concepts to assess and manage the initial encounter of a poisoned patient from the perspective of emergency medicine. Methods: a bibliographic review of the scientific literature was carried out, presenting the current evidence of the management and therapeutic interventions currently used in an intoxicated patient.

Quiste Vallecular: Caso clínico de estridor agudo / Vallecular cyst: clinical case of acute stridor

El enfrentamiento de estridor en el Servicio de Urgencias puede ser un desafío para el clínico. La mayoría de los pacientes responderán a medidas estándar de anafilaxia, no obstante, ante pacientes refractarios a tratamiento se deben sospechar otras patologías. Presentamos el caso clínico de una paciente refractaria a manejo de anafilaxia. Se realiza videolaringoscopía que identifica quiste de vallécula y se maneja mediante protección de vía aérea con intubación orotraqueal. Se decide escisión quirúrgica, en la cual se identifica estenosis subglótica que requiere instalación de traqueostomía. La paciente evoluciona favorablemente y es dada de alta.

Coping with stridor in the Emergency Department can challenge the clinician. Most patients respond to standard anaphylaxis measures. The clinician should suspect other differential diagnoses when patients are refractory to treatment. We present the clinical case of a patient refractory to standard anaphylaxis management. A video laryngoscopy was performed, identifying a vallecula cyst. We secured the airway through orotracheal intubation. The surgical team of our hospital performed a surgical excision of the cyst and identified subglottic stenosis, which required the installation of a tracheostomy. The patient evolved favorably in the postoperative period and was discharged.

POLYEMBOLOKOILAMANIA IN THE EMERGENCY DEPARTMENT.

Polyembolokoilamania is a rare but serious medical condition that involves the presence of multiple foreign bodies in the patient's body.

Prediction of adverse cardiac outcomes in high-risk Mexican patients with chest pain in the emergency department / Desenlaces adversos cardiovasculares en pacientes mexicanos de alto riesgo con dolor torácico en el servicio de urgencias

Abstract Objective: The aim of the study was to compare the discriminative power and accuracy for prediction of MACE of five commonly used scoring tools in Mexican patients with chest pain who present to the ED. Methods: A single-center, prospective, observational, and comparative study of patients admitted to the ED with chest pain as the chief complaint. Five chest pain scoring systems were calculated. The primary endpoint was the composite of cardiovascular death, myocardial infarction, coronary intervention, coronary artery bypass grafting, or readmission for cardiovascular causes within 30 days. Results: A total of 168 patients were studied. The score which provided the highest area under the curve of 0.76 (95% CI: 0.70-0.85) was history, ECG, age, risk factors, and troponin (HEART) score. In addition, the integrated discrimination index for the HEART score was 6% higher when compared to the other four scores. Conclusions: The HEART score provided the best classification tool for identifying those patients at highest risk for MACE, either alone or by adding their results to other classification scores, even in a comorbid population.

Resumen Objetivo: Comparar el poder discriminativo y precisión diagnóstica de Eventos Cardiovasculares Mayores (ECVM) de cinco escalas de clasificación de dolor torácico de uso común en pacientes mexicanos con dolor torácico que acuden al servicio de urgencias. Métodos: Estudio prospectivo, observacional y comparativo que incluyó a pacientes ingresados en urgencias que presentaban dolor torácico como síntoma cardinal. Se calcularon cinco escalas de puntuación de dolor torácico. El desenlance principal fue el compuesto de muerte cardiovascular, infarto de miocardio, intervención coronaria, injerto de derivación de arteria coronaria o reingreso por causas cardiovasculares dentro de los 30 días. Resultados: Se estudió un total de 168 pacientes. La escala de puntuación que proporcionó el área bajo la curva más alta de 0.76 (IC de 95%: 0.70-0.85) fue la escala de historia clínica, ECG, edad, factores de riesgo y troponina (HEART, por sus siglas en inglés). Además, el indice de discriminación efectiva para la puntuación HEART fue un 6% más alto en comparación con las otras cuatro escalas de puntuación. Conclusiones: La escala de HEART proporcionó la mejor herramienta de clasificación para idenfiticar a los pacientes con mayor riesgo de ECVM, ya sea solo a agregando sus resultados a otros puntajes de clasificación, incluso en una población comórbida.

Clinical Characteristics and Interventions for Ingested Magnetic Foreign Bodies in Children: A Systematic Review and Meta-analysis

Background: Ingested foreign materials are a common cause for hospital emergency department visit. Foreign objects such as magnets found in the gastrointestinal tract can cause serious problem because magnets attract to each other across the intestinal wall, often resulting in severe damage. We aimed to review the magnitude of the problem, the clinical characteristics and the interventions related to this problem. Methods: A systematic review and meta-analysis of the retrospective studies published in PUBMED, MEDLINE, Web of Science, Embase and Cochrane was conducted. The search was limited to studies published from Jan 1, 2000 to July 31, 2022, with the last search done on August 1, 2022. No publication restrictions or study design filters were applied. Results: Data from 24 retrospective cohort studies with 2014 patients were included in the review. 63.6% (95% CI 59.9%-67.3%) of children who had swallowed foreign bodies were male, and 43% (95% CI 29.3%-57.3%) children presented with non-specific symptoms or had a complete absence of symptoms. Only 74.7% (95% CI 58.7%-88%) of the children has clear history of ingested foreign bodies. Abdominal surgery was the most prevalent interventions (43.3%, 95%CI 32.5%-54.1%) among the inpatients, while conservative treatments were the second common intervention (40.3%, 95%CI 27.8%–52.9%) among the inpatients and outpatients. Intestinal perforation or fistula occurred in 30.2% (95%CI 22.5%–37.8%) children. Conclusions: Despite significant heterogeneity among primary studies, our results detail the morbidity, clinical characteristics and interventions associated with ingested magnetic foreign bodies in children.

Elaboração de diretrizes para atendimento hospitalar de tentativas de suicídio na adolescência / Development of guidelines for hospital care of suicide attempts in adolescence

Resumo Este artigo visa descrever um estudo qualitativo e quantitativo de construção e validação de diretrizes para atendimento hospitalar de adolescentes com tentativa de suicídio O percurso metodológico implicou a realização de revisão integrativa de literatura com análise temática de conteúdo de 27 artigos, o qual gerou 3 categorias: avaliação do comportamento suicida em contexto de urgência e emergência hospitalar; intervenção diante do comportamento suicida e equipe multiprofissional hospitalar. O conteúdo destas categorias fundamentou a construção de um instrumento com 15 afirmativas sobre a atuação com adolescentes em crise suicida atendidos no contexto hospitalar. Este instrumento foi aplicado com 20 profissionais de saúde selecionados em duas instituições hospitalares do sul do Brasil, os quais atuaram como juízes/avaliadores das afirmativas propostas. O conteúdo das 15 afirmativas foi validado como diretrizes através do Cálculo de Porcentagem de Concordância e do Cálculo do Escore. As diretrizes construídas podem auxiliar as equipes multiprofissionais hospitalares, diante dos adolescentes com tentativas de suicídio, a fundamentarem suas condutas a partir de critérios que norteiam ações de acolhimento, avaliação, intervenção e encaminhamento.

Abstract This article aims to describe a qualitative and quantitative study of the construction and validation of guidelines for hospital care of adolescents with suicide attempts. The methodological approach involved an integrative literature review with thematic content analysis of 27 articles, which generated 3 categories: assessment of suicidal behavior in the context of the emergency department; intervention in suicidal behavior, and hospital multidisciplinary team. The content of these categories was the basis for the construction of an instrument with 15 statements about the performance of adolescents in suicidal crisis assisted in the hospital setting. This instrument was applied with 20 healthcare professionals selected from two hospital institutions in southern Brazil, who acted as judges/evaluators of the proposed statements. The content of the 15 statements was validated as guidelines through the Percentage of Concordance Calculation and the Score Calculation. The constructed guidelines may help multidisciplinary hospital teams when facing adolescents with suicide attempts, to base their conduct on criteria that guide actions of reception, assessment, intervention, and referral.

INTRODUÇÃO: No cotidiano do hospital, inevitavelmente, a equipe de saúde se relaciona com pacientes e familiares que receberam algum tipo de má notícia. Constituindo-se como uma tarefa árdua, porém fundamental, a comunicação de más notícias é um importante tema de estudo na área da saúde. OBJETIVOS: O objetivo é descrever e analisar quais são os sentidos subjetivos atribuídos pelos profissionais às reações da família a uma comunicação de más notícias. Os objetivos específicos foram: identificar processos simbólicos e práticas reguladoras da produção de sentidos; analisar como se apresenta a emocionalidade dos profissionais envolvidos nas situações de comunicação de más notícias; e analisar como o contexto de pronto socorro atua enquanto mediador de produções simbólico-emocionais dos profissionais. MÉTODO: Participaram deste estudo profissionais de um pronto socorro de um hospital universitário da cidade de São Paulo. Foram apresentadas três vinhetas de casos clínicos que retratam diferentes reações de familiares de pacientes após uma comunicação de más notícias, no Pronto Socorro. A partir de uma pergunta disparadora, conduziu-se uma entrevista semi-estruturada. RESULTADOS: Evidenciou-se que ausência da instrumentalização para a comunicação de más notícias durante a graduação em medicina e enfermagem repercute em diversos âmbitos da experiência do profissional, desde como administram suas próprias emoções até o modo como lidam com as múltiplas reações emocionais dos familiares dos pacientes. CONSIDERAÇÕES FINAIS: Este estudo sugere, então, a relevância de haver, durante a formação profissional, maior espaço para estudo e discussão sobre os temas que emergem em um contexto de comunicação de más notícias.

INTRODUCTION: In the daily routine of the hospital, inevitably, the health team interacts with patients and family members who have received some kind of bad news. Constituting itself as an arduous but fundamental task, the communication of bad news is an important topic of study in the health area. OBJECTIVES: We aim to describe and analyze what are the subjective sense attributed by professionals to the family's reactions to a communication of bad news. The specific objectives were: to identify symbolic processes and regulatory practices of the sense make; to analyze how the emotionality of the professionals involved in the communication of bad news is presented; and to analyze how the emergency department context acts as a mediator of symbolic-emotional productions of professionals. METHOD: Professionals from an emergency department of a university hospital in the city of São Paulo participated in this study. Three vignettes of clinical cases were presented that depict different reactions of patients' relatives after a communication of bad news, in the emergency department. From a triggering question, a semi-structured interview was conducted.

Síndrome HELLP y rotura hepática en un embarazo gemelar: presentación de un caso / HeLLP Syndrome and Hepatic Rupture in a Twin Pregnancy: A Case Report / Síndrome HeLLP e ruptura hepática em gestação gemelar: relato de caso

Introducción: el síndrome HELLP y rotura hepática es una complicación poco frecuente, especialmente en casos de embarazo gemelar. Se presenta el caso de un hematoma subcapsular hepático roto por síndrome HELLP que complicó un embarazo gemelar que requirió una cesárea de emergencia y para el manejo de la hipovolemia, el empaquetamiento hepático. Presentación del caso: mujer de 41 años, con gestación gemelar de 35 semanas, quien acudió al servicio de emergencia, por contracciones uterinas y ausencia de movimientos fetales. Ante una bradicardia severa de ambos fetos, se optó por una cesárea de urgencia. Al abrir la cavidad abdominal, se encontró hemoperitoneo y se logró extraer ambos fetos vivos. Se realizó una laparotomía media, supra e infraumbilical exploradora (poscesárea) y se halló una rotura hepática del lóbulo derecho. Se procedió a un empaquetamiento hepático con compresas y cierre temporal abdominal; entre tanto, el manejo del shock hipovolémico y la preeclampsia se continuó en la unidad de cuidados intensivos. La paciente se fue de alta en buenas condiciones a los 21 días. Conclusión: el síndrome HELLP produce complicaciones graves, como rotura hepática, que si no es tratada de forma correcta, temprana y multidisciplinaria, puede llevar a producir mortalidad materno-perinatal.

Introduction: HELLP syndrome and hepatic rupture are rare complications, especially in the case of twin pregnancy. Here, we present a case of ruptured hepatic subcapsular hematoma due to HELLP syndrome that caused complication in a twin pregnancy. This case required emergency Cesarean section and management of hypo- volemia hepatic packing. Case presentation: A 41-year-old female pregnant with twins (35 weeks) came to the emergency room for uterine contractions and absence of fetal movements. Due to severe bradycardia in both fetuses, emergency Cesarean section was performed. When the abdominal cavity was opened, hemoperitoneum was found, and both fetuses were extracted alive. A median, supra-, and infraumbilical exploratory laparotomy (post Cesarean section) was performed, and right lobe hepatic rupture was found. Subsequently, hepatic packing with compression and temporary abdominal closure was performed. Hypovolemic shock and preeclampsia was continuously managed in the intensive care unit. At 21 days, the patient was discharged in good condition. Conclusion: HELLP syndrome causes serious complications, such as hepatic rupture, which may lead to maternal and perinatal mortality if not correctly treated early in a multidisciplinary manner.

Introdução: a síndrome HELLP e a ruptura hepática são complicações raras, especialmente em casos de gravidez gemelar. Neste artigo, apresentamos o caso de um hematoma subcapsular hepático rompido devido à síndrome HELLP que complicou uma gravidez gemelar que exigiu uma cesariana de emergência e tamponamento hepático para o manejo da hipovolemia. Apresentação do caso: mulher, 41 anos, gestação gemelar de 35 semanas, recorre ao pronto-socorro por contrações uterinas e ausência de movimentos fetais. Devido à bradicardia grave em ambos os fetos, foi decidida uma cesariana de emergência. Ao abrir a cavidade abdominal o hemoperitônio é localizado, sendo possível extrair ambos os fetos vivos. Foi realizada laparotomia exploradora mediana, supra e infraumbilical (pós-cesariana) sendo constatada ruptura hepática do lobo direito. Foi realizado tamponamento hepático com compressas e fechamento abdominal temporário, e o manejo do choque hipovolêmico e da pré-eclâmpsia foi mantido na Unidade de Terapia Intensiva, onde a paciente recebeu alta em boas condições após 21 dias. Conclusão: a síndrome HELLP produz complicações graves como a ruptura hepática que, se não tratada de forma precoce e multidisciplinar, pode levar à mortalidade materna perinatal.

Epidemiology of headache in a neurological Emergency Department in Medellin, Colombia / Epidemiology of headache in a neurological Emergency Department in Medellin, Colombia

Introduction:Headache is a common reason for presentation to emergency departments (ED) around the world. In many countries, ED are not speciality-focussed, however, in Colombia and some other countries, specialist neurological hospitals have ED with a strong neurological focus. For patients presenting with headache, these ED may have different epidemiology, investigation strategies and treatment patterns from general ED. Objective:The objective of this study was to describe the epidemiology of headache presenting to the ED of Instituto Neurológico de Colombia in Medellin, Colombia ­ an ED which is a referral centre for neurological and neurosurgical diseases. Methods:This was an observational study by chart review of adults (aged ≥18) with a main presenting compliant of headache. Demographic, clinical, imaging, diagnoses and outcome data were collected. The primary outcome of interest was the rate of serious secondary intracranial headache cause. Analysis was descriptive. Results:757 patients were studied ­ female 76%, median age 39. Most headache were of gradual onset (85%) and new neurological signs were uncommon (4%). CT was performed in 50% of cases and MRI in 20%. A wide variety of headache causes were identified. Serious secondary intracranial headache was identified in 8.9% (95% CI 7.1-11.1%) of cases. Most patients (89%) were discharged home from ED. Conclusion:Diagnosis of headache in ED is challenging with a very wide range of possible causes. A small proportion of patients (approx. 9%) have a serious cause for their symptoms ­ a proportion similar to that reported in other international emergency department cohorts.

Introdução: A cefaleia é um motivo comum de apresentação aos departamentos de emergência (DE) em todo o mundo. Em muitos países, os PS não são focados em especialidades, no entanto, na Colômbia e em alguns outros países, os hospitais neurológicos especializados têm PS com um forte foco neurológico. Para pacientes que apresentam cefaleia, esses DE podem ter epidemiologia, estratégias de investigação e padrões de tratamento diferentes dos DE geral. Objetivo: O objetivo deste estudo foi descrever a epidemiologia da dor de cabeça apresentada ao pronto-socorro do Instituto Neurológico de Colômbia em Medellín, Colômbia ­ um pronto-socorro que é um centro de referência para doenças neurológicas e neurocirúrgicas. Métodos: Este foi um estudo observacional por meio de revisão de prontuários de adultos (idade ≥18) com apresentação principal complacente de cefaleia. Dados demográficos, clínicos, de imagem, diagnósticos e resultados foram coletados. O desfecho primário de interesse foi a taxa de causa grave de dor de cabeça intracraniana secundária. A análise foi descritiva. Resultados: Foram estudados 757 pacientes ­ 76% do sexo feminino, idade mediana de 39 anos. A maioria das cefaleias foi de início gradual (85%) e os novos sinais neurológicos foram incomuns (4%). A tomografia computadorizada foi realizada em 50% dos casos e a ressonância magnética em 20%. Uma grande variedade de causas de dor de cabeça foi identificada. Cefaleia intracraniana secundária grave foi identificada em 8,9% (IC 95% 7,1-11,1%) dos casos. A maioria dos pacientes (89%) recebeu alta do pronto-socorro. Conclusão: O diagnóstico de cefaleia no DE é desafiador, com uma ampla gama de causas possíveis. Uma pequena proporção de pacientes (aproximadamente 9%) tem uma causa grave para os seus sintomas ­ uma proporção semelhante à relatada em outras coortes internacionais de serviços de emergência.

Epidemiology and outcomes of geriatric trauma patients consulting at the center hospitalier universitaire de Kigali emergency department

Background Life expectancy in low- and middle-income countries (LMIC) continues to rise, resulting in a growing geriatric population. In Rwanda, a sub-Saharan LMIC, traumatic injuries are a common cause of mortality and morbidity. However, little is known about the frequency and type of traumatic injuries among geriatric populations in Rwanda. Objective We explored the epidemiology and outcomes of trauma for geriatric patients presenting to the emergency department (ED) of the center Hospitalier Universitaire de Kigali (CHUK) in Rwanda. Methods This prospective cross-sectional study was conducted from July 2019 to January 2020 at the ED of CHUK. Trauma patients aged 65 and above and alive at the time of evaluation were eligible for inclusion. Demographic characteristics were collected along with triage category, mechanism of injury, transfer status, transport method to CHUK, time spent at the ED, complications, and mortality predictors. Results For the 100 patients enrolled, the most common injury mechanism was falls (63%), followed by road traffic accidents (28%). The majority of patients spent less than 48 h in the ED (63%). The mortality rate was 14%, with most deaths resulting from injury-related complications. Triage category, Kampala Trauma Score, and Glasgow Coma Scale were significant predictors of mortality, with p-values of 0.002, <0.001, and <0.001, respectively. Conclusions The epidemiology of geriatric trauma found in this study can inform public health and clinical guidelines. Interventions targeting falls and road traffic accidents would target the most common geriatric trauma mechanisms, and clinical protocols that take into account predictors of mortality could improve outcomes and increase life expectancy for this population.

Systemic emergency department performance in a low resource tertiary health facility in central Kenya: Micro level emergency care system evaluation

Introduction Helicopter Emergency Medical Services (HEMS) is integrated into modern emergency medical services because of its suggested mortality benefit in certain patient populations, it is an expensive resource and appropriate use/feasibility in low- to middle income countries (LMIC) is highly debated. To maximise benefit, correct patient selection in HEMS is paramount. To achieve this, current practices first need to be described. The study aims to describe a population of patients utilising HEMS in South Africa, in terms of flight data, patient demographics, provisional diagnosis, as well as clinical characteristics and interventions. Methods A retrospective flight- and patient-chart review were conducted, extracting clinical and mission data of a single aeromedical operator in South Africa, over a 12-month period (July 2017 ­ June 2018) in Gauteng, Free State, Mpumalanga and North-West provinces. Results A total of 916 cases were included (203 primary cases, 713 interfacility transport (IFT) cases). Most patients transported were male (n=548, 59.8%) and suffered blunt trauma (n=379, 41.4%). Medical pathology (n=247, 27%) and neonatal transfers (n=184, 20.1%) follows. Flights occurred mainly in daylight hours (n=729, 79.6%) with median mission times of 1-hour 53 minutes (primary missions), and 3 hours 10 minutes (IFT missions). Median on-scene times were 26 minutes (primary missions) and 55 minutes (IFT missions). Almost half were transported with an endotracheal tube (n=428, 46.7%), with a large number receiving no respiratory support (n=414, 45.2%). No patients received fibrinolysis, defibrillation, cardioversion or cardiac pacing. Intravenous fluid therapy (n=867, 94.7%) was almost universal, with common administration of sedation (n=430, 46.9%) and analgesia (n=329, 35.9%). Conclusion Apart from the lack of universal call-out criteria and response to the high burden of trauma, HEMS seem to fulfil an important critical care transport role. It seems that cardiac pathologies are under-represented in this study and might have an important implication for crew training requirements.

Treatment and factors associated with prognosis of hyperkalemia in the emergency department / 中华危重病急救医学

Objective:To survey treatment and prognosis of hyperkalemia patients in the emergency department and to analyze factors associated with all-cause in-hospital mortality.Methods:We implemented electronic hospital information system, extracted demographic characteristics, underlying diseases, laboratory findings, potassium lowering therapy and prognosis of hyperkalemia patients [age ≥ 18 years, serum potassium (K +) concentration ≥ 5.5 mmol/L] in the emergency department of Peking Union hospital in Beijing between June 1st 2019 to May 31st 2020. The enrolled subjects were divided into the non-survival group and the survival group according to their prognosis. Univariate analysis and Cox regression model were adopted to analyze factors affecting all-cause in-hospital mortality of hyperkalemia patients. Results:A total of 579 patients [median age 64 (22) years; 310 men (53.5%) and 269 women (46.5%)] with hyperkalemia were enrolled, among which, 317 (54.7%), 143 (24.7%) and 119 (20.6%) were mild, moderate, and severe hyperkalemia, respectively. 499 (86.20%) patients received potassium-lowering therapy, forty-four treatment regimens were administered. Insulin and glucose (I+G, 61.3%), diuretics (Diu, 57.2%), sodium bicarbonate (SB, 41.9%) and calcium gluconate/chloride (CA, 44.4%) were commonly used for the treatment of hyperkalemiain the emergency department. The combination of insulin and glucose, calcium gluconate/chloride, diuretics and sodium bicarbonate (I+G+CA+Diu+SB) was the most favored combined treatment regimen of hyperkalemia in the emergency department. The higher serum potassium concentration, the higher proportion of administrating combined treatment regimen and/or hemodialysis (HD) (the proportion of administrating combined treatment regimen in mild, moderate, and severe hyperkalemia patients were 58.4%, 82.5% and 94.8%; the proportion of administrating HD in mild, moderate, and severe hyperkalemia patients were 9.7%, 13.3% and 16.0%, respectively). The proportion of achievement of normokalaemia elevated as the kinds of potassium lowering treatment included in the combined treatment regimen increased. The proportion of achievement of normokalaemia was 100% in the combined treatment regimen including 6 kinds of potassium lowering therapy. Among various potassium lowering treatments, HD contributed to the highest rate of achievement of normokalaemia (93.8%). 111 of 579 (19.20%) hyperkalemia patients died in hospital. Cox regression model revealed that complicated with cardiac dysfunction predicted higher mortality [hazard ratio ( HR) = 1.757, 95% confidence interval (95% CI) was 1.155-2.672, P = 0.009]. Achievement of normokalaemia and administration of diuretics attributed to lower mortality ( HR = 0.248, 95% CI was 0.155-0.398, P = 0.000; HR = 0.335, 95% CI was 0.211-0.531, P = 0.000, respectively). Conclusions:Treatment of hyperkalemia in the emergency department were various. Complicated with cardiac dysfunction were associated with higher mortality. Achieving normokalaemia was associated with decreased mortality.

Objective:To investigate the influence of the teaching model based on the synergy of medical education on the objective structured clinical examination (OSCE) scores and critical thinking ability of interns in emergency department.Methods:A total of 84 students who studied as interns in Emergency Department of our hospital from January 2020 to 2021 were selected as research subjects, and they were divided into observation group and control group using a random number table, with 42 students in each group. The students in the control group were taught using traditional methods, while those in the observation group were taught based on the synergy of medical education. Both groups received an OSCE examination, and the two groups were compared in terms of OSCE score, critical thinking ability, and evaluation of teaching. SPSS 22.0 was used to perform the t-test and the chi-square test. Results:Compared with the control group, the observation group had significantly higher scores of theoretical assessment, disease assessment, first aid measures, special skills, use of medical instruments, communication skills with SP, and medical record writing and a significantly higher total score of OSCE assessment ( P<0.05). After teaching, both groups had a significant increase in the score of critical thinking ability, and the observation group had a significantly higher score than the control group [(306.38±25.76) vs. (280.39±20.17)]. The observation group had a significantly higher degree of satisfaction with teaching than the control group ( P<0.05). Conclusion:The teaching model based on the synergy of medical education can improve the OSCE score of interns in emergency department and cultivate their critical thinking ability, and there is a relatively high degree of satisfaction with this teaching model.

Application of objective-based teaching combined with Roy adaptive situational teaching in emergency nursing teaching / 中华医学教育探索杂志

Objective:To investigate the application of objective-based teaching combined with Roy adaptive situational teaching in emergency nursing teaching.Methods:A total of 110 nursing students who were assigned to Emergency Department of Xijing Hospital, The First Affiliated Hospital of Air Force Medical University, as interns were selected and divided into control group and observation group according to the order of admission, with 55 students in each group. The students in the control group received traditional teaching, while those in the observation group received objective-based teaching combined with Roy adaptive situational teaching. The two groups were evaluated in terms of the assessment score of situational simulation and the ability for emergency medicine and treatment. SPSS 22.0 was used to perform the t-test and the chi-square test. Results:For the nursing students in the observation group, the mean scores of theoretical knowledge objective, skill objective, and attitude objective were (9.09±1.21) points, (13.98±1.87) points, and (9.32±0.95) points, respectively, and for those in the control group, the mean scores of these objectives were (8.41±1.17) points, (12.43±1.72) points, and (8.72±0.83) points, respectively, suggesting that compared with the control group, the observation group had a significantly higher mastery degree of the teaching objectives (theoretical knowledge objective, skill objective, and attitude objective) ( P < 0.05). The observation group had significantly better abilities for emergency medicine and treatment than the control group ( P < 0.05). Conclusion:Objective-based teaching combined with Roy adaptive situational teaching can be used in emergency nursing teaching and may help to improve the theoretical and practical skills of nursing students and cultivate the abilities for emergency medicine and treatment.

Research on the Correlation between Hospital Ethical Atmosphere and Work Engagement of Emergency Department Nurses / 中国医学伦理学

【Objective:】 To explore the correlation between hospital ethics atmosphere and work engagement of nurses in emergency department, and provide a basis for reasonably solving ethical issues and improving nurses’ work engagement. 【Methods:】 From May 2019 to May 2021, the convenient sampling method was used to select 350 nurses from emergency departments of four tertiary or above hospitals in Xi’an as the research subjects. The Ethical Climate Cognitive Scale and the Work Engagement Scale were used to evaluate the hospital ethical atmosphere and work engagement of nurse, and analyze their correlation. The univariate factor analysis and multiple factor analysis were used to explore the influencing factors. 【Results:】 The work engagement score of emergency department nurses was (51.69±11.09) points, and the ethical atmosphere score was (72.78±11.45) points. The results of univariate analysis showed that there were statistically significant differences in the work engagement scores among emergency department nurses with different educational backgrounds, hospital grades, hospital employment methods, and whether they had received ethics training (P<0.05). The results of multiple factor analysis indicated that the cognition of hospital ethical atmosphere, hospital employment methods, and whether they had received ethics education and training were all factors that affected work engagement (P<0.05). 【Conclusion:】 The hospital ethical atmosphere is positively correlated with the work engagement of emergency department nurse. The ethical atmosphere and work engagement of nurses are both at a moderate level, with significant room for improvement. Therefore, it is necessary to continue to strengthen the management support of emergency nursing work and improve the perceived level of recognition and respect among emergency department nurses in the organization.
