Reliability and Accuracy of the Pediatric Swiss Emergency Triage Scale-the SETSped Study.

BACKGROUND AND IMPORTANCE: The Swiss Emergency Triage Scale (SETS) is an adult triage tool used in several emergency departments. It has been recently adapted to the pediatric population but, before advocating for its use, performance assessment of this tool is needed. OBJECTIVES: The purpose of this study was to assess the reliability and the accuracy of the pediatric version of the SETS for the triage of pediatric patients. DESIGN, SETTING, AND PARTICIPANTS: This study was a cross-sectional study among a sample of emergency triage nurses (ETNs) exposed to 17 clinical scenarios using a computerized simulator. OUTCOME MEASURES AND ANALYSIS: The primary outcome was the reliability of the triage level performed by the ETNs. It was assessed using an intraclass correlation coefficient.Secondary outcomes included accuracy of triage compared with expert-based triage levels and factors associated with accurate triage. MAIN RESULTS: Eighteen ETNs participated in the study and completed the evaluation of all scenarios, for a total of 306 triage decisions. The intraclass correlation coefficient was 0.80 (95% confidence interval, 0.69-0.91), with an agreement by scenario ranging from 61.1% to 100%. The overall accuracy was 85.8%, and nurses were more likely to undertriage (16.0%) than to overtriage (4.3%). No factor for accurate triage was identified. CONCLUSIONS: This simulator-based study showed that the SETS is reliable and accurate among a pediatric population. Future research is needed to confirm these results, compare this triage scale head-to-head with other recognized international tools, and study the SETSped in real-life setting.

[Emergency medicine: what's new in 2023]. / Médecine d'urgence: ce qui a changé en 2023.

Research in prehospital and in-hospital emergency medicine is essential to the development of this discipline. By calling certain practices into question (thrombolysis for minor strokes, use of coagulation factors for patients with severe polytrauma), providing access to new technologies (video-laryngoscopy, POCT troponins in pre-hospital care) or questioning new practices (double defibrillation, pulmonary US in pneumonia), research enables emergency physicians to adapt their day-to-day practice.

La recherche en médecine d'urgence, tant sur le plan préhospitalier qu'hospitalier, est nécessaire et même indispensable à la fois au développement de cette discipline, mais également à la reconnaissance de ses spécificités. Par la remise en question de certaines pratiques (thrombolyse pour les AVC mineurs, utilisation de facteurs de la coagulation pour le polytraumatisé sévère), l'accès à de nouvelles technologies (vidéo-laryngoscopie, troponines POCT en préhospitalier) ou le questionnement sur de nouvelles pratiques (double défibrillation, US pulmonaire dans la pneumonie), la recherche permet aux urgentistes d'adapter leur pratique quotidienne à l'état de l'art.

Anti-inflammatory effect of biologic therapy in patients with psoriatic disease: A prospective cohort FDG PET study.

AIM: The aim of the study was to evaluate the changes in central vascular inflammation measured by FDG PET and myocardial blood flow reserve (MFR) determined by 82Rb PET following therapy with biologic agents for 6 months in patients with psoriatic arthritis (PsA) and/or cutaneous psoriasis (PsO) (group 1) and compare with PsO subjects receiving non-biologic therapy (group 2) and controls (group 3). METHODS AND RESULTS: Target-to-background ratio (TBR) by FDG PET in the most diseased segment of the ascending aorta (TBRmax) was measured to assess vascular inflammation. 82Rb PET studies were used to assess changes in left ventricular MFR. A total of 34 participants were enrolled in the study (11 in group 1, 13 in group 2, and 10 controls). A significant drop in the thoracic aorta uptake was observed in the biologic-treated group (ΔTBRmax: - .46 ± .55) compared to the PsO group treated with non-biologic therapy (ΔTBRmax: .23 ± .67). Those showing response to biologic agents maintained MFR compared to who showed no response. CONCLUSION: In a cohort of psoriasis patients treated with biologics, FDG uptake in the thoracic aorta decreased over the study period. Patients who demonstrated a significant anti-inflammatory response on FDG PET imaging maintained their MFR compared to non-responders.

Assessment of frailty by paramedics using the clinical frailty scale - an inter-rater reliability and accuracy study.

BACKGROUND: Frailty assessment by paramedics in the prehospital setting is understudied. The goals of this study were to assess the inter-rater reliability and accuracy of frailty assessment by paramedics using the Clinical Frailty Scale (CFS). METHODS: This was a cross-sectional study with paramedics exposed to 30 clinical vignettes created from real-life situations. There was no teaching intervention prior to the study and paramedics were only provided with the French version of the CFS (definitions and pictograms). The primary outcome was the inter-rater reliability of the assessment. The secondary outcome was the accuracy, compared with the expert-based assessment. Reliability was determined by calculating an intraclass correlation coefficient (ICC). Accuracy was assessed through a mixed effects logistic regression model. A sensitivity analysis was carried out by considering that an assessment was still accurate if the score differed from no more than 1 level. RESULTS: A total of 56 paramedics completed the assessment. The overall assessment was found to have good inter-rater reliability (ICC = 0.87 [95%CI 0.81-0.93]). The overall accuracy was moderate at 60.6% (95%CI 54.9-66.1) when considering the full scale. It was however much higher (94.8% [95%CI 92.0-96.7] when close assessments were considered as accurate. The only factor associated with accurate assessment was field experience. CONCLUSION: The assessment of frailty by paramedics was reliable in this vignette-based study. However, the accuracy deserved to be improved. Future research should focus on the clinical impact of these results and on the association of prehospital frailty assessment with patient outcomes. REGISTRATION: This study was registered on the Open Science Framework registries ( https://doi.org/10.17605/OSF.IO/VDUZY ).

[LGBTQIA+ people: care issues in the emergency department]. / Personnes LGBTQIA+ : enjeux de prise en charge aux urgences.

Visits to the emergency department are often a difficult time for LGBTQIA+ people, mainly because of the frequent discrimination in healthcare environments and the lack of knowledge of medical and nursing staff. This article begins by presenting some epidemiological features, before discussing specific issues such as contraception and fertility, hormone therapy, sexually transmitted infections, surgical complications, psychiatric pathologies, and traumatology, from the perspective of the emergency physician. Finally, suggestions for further reflection and improvement are proposed.

Les visites aux urgences représentent souvent des moments difficiles pour les personnes LGBTQIA+, principalement en raison des discriminations particulièrement fréquentes dans les milieux de soins et du manque de connaissances du personnel médico-soignant. Cet article présente dans un premier temps quelques chiffres épidémiologiques, avant de discuter des enjeux spécifiques, comme la contraception et la fertilité, l'hormonothérapie, les infections sexuellement transmissibles, les complications opératoires, les pathologies psychiatriques ou la traumatologie, le tout sous le prisme de l'urgentiste. Enfin, des pistes de réflexion et d'amélioration sont proposées.

[Interdisciplinarity and critical care in emergency medicine]. / Interdisciplinarité et urgences vitales en médecine d'urgence.

Cardiorespiratory arrest, stroke and severe trauma have serious consequences if untreated with strict procedures in a timely manner. This temporal imperative implies the implementation of a succession of actions coordinated by healthcare providers with diverse expertise, and operating according to known, mastered and trained standards of care. Simple and clear communication principles ensure the consistency and fluidity of these actions. Competent and inclusive leadership promotes the achievement of set objectives and allows the team to adapt to demanding or unforeseen situations. Interdisciplinarity as it is practiced in the emergency setting for critical pathways such as those mentioned, then takes on its full meaning.

L'arrêt cardiorespiratoire, l'accident vasculaire cérébral et le traumatisé grave sont grevés de lourdes conséquences s'ils ne sont pas traités avec des procédures strictes dans des délais adéquats. Cet impératif temporel implique la mise en œuvre d'une succession d'actions coordonnées par des intervenants à l'expertise diverse et opérant selon des standards de soins connus, maîtrisés et entraînés. Des principes de communication simples et clairs assurent la cohérence et la fluidité de ces actions. Un leadership, compétent et inclusif, favorise l'atteinte des objectifs fixés et permet l'adaptation de l'équipe aux situations exigeantes ou imprévues. L'interdisciplinarité telle qu'elle est pratiquée pour ces filières de soins critiques prend alors tout son sens.

[Updates in emergency medicine]. / Médecine d'urgence.

In 2021, emergency medicine has been impacted by the Covid19 pandemic. The repercussions were both on clinical and scientific aspects specific to our discipline. For this special issue, we have chosen not to insist on the pandemic but to return to some fundamentals of our discipline: cardiovascular emergencies remain the leading cause of death in the world and the aspects of risk stratification of pathologies such as acute coronary syndromes or neurovascular attack remain a daily issue within the framework of the strategies of management and investigation in emergency medicine. In addition, the consideration of alternative treatments in the context of pathologies, ranging from cannabis consumption to cardiac arrest and atrial fibrillation, also remains a daily challenge.

En 2021, la médecine d'urgence a été impactée par la pandémie Covid19. Les répercussions ont autant été cliniques que sur la recherche scientifique spécifique à notre discipline. Pour ce numéro spécial, nous avons fait le choix de ne pas insister sur la pandémie, mais de revenir à certains fondamentaux de notre discipline : l'urgence cardiovasculaire reste la première cause de mortalité dans le monde. Les aspects de stratification du risque pour ces pathologies, telles que les syndromes coronariens aigus ou les AVC, sont toujours un enjeu quotidien dans le cadre des stratégies de prise en charge et d'investigation en urgence. Par ailleurs, la prise en compte d'alternatives thérapeutiques dans des pathologies très variées, allant de la consommation de cannabis à l'arrêt cardiaque en passant par la fibrillation auriculaire, reste également un enjeu au quotidien.

Association between prehospital arterial hypercapnia and mortality in acute heart failure: a retrospective cohort study.

BACKGROUND: Acute Heart Failure (AHF) is a potentially lethal pathology and is often encountered in the prehospital setting. Although an association between prehospital arterial hypercapnia in AHF patients and admission in high-dependency and intensive care units has been previously described, there is little data to support an association between prehospital arterial hypercapnia and mortality in this population. METHODS: This was a retrospective study based on electronically recorded prehospital medical files. All adult patients with AHF were included. Records lacking arterial blood gas data were excluded. Other exclusion criteria included the presence of a potentially confounding diagnosis, prehospital cardiac arrest, and inter-hospital transfers. Hypercapnia was defined as a PaCO2 higher than 6.0 kPa. The primary outcome was in-hospital mortality, and secondary outcomes were 7-day mortality and emergency room length of stay (ER LOS). Univariable and multivariable logistic regression models were used. RESULTS: We included 225 patients in the analysis. Prehospital hypercapnia was found in 132 (58.7%) patients. In-hospital mortality was higher in patients with hypercapnia (17.4% [23/132] versus 6.5% [6/93], p = 0.016), with a crude odds-ratio of 3.06 (95%CI 1.19-7.85). After adjustment for pre-specified covariates, the adjusted OR was 3.18 (95%CI 1.22-8.26). The overall 7-day mortality was also higher in hypercapnic patients (13.6% versus 5.5%, p = 0.044), and ER LOS was shorter in this population (5.6 h versus 7.1 h, p = 0.018). CONCLUSION: Prehospital hypercapnia is associated with an increase in in-hospital and 7-day mortality in patient with AHF.

Prehospital arterial hypercapnia in acute heart failure is associated with admission to acute care units and emergency room length of stay: a retrospective cohort study.

BACKGROUND: Acute Heart Failure (AHF) is a common condition that often presents with acute respiratory distress and requires urgent medical evaluation and treatment. Arterial hypercapnia is common in AHF and has been associated with a higher rate of intubation and non-invasive ventilation in the Emergency Room (ER), but its prognostic value has never been studied in the prehospital setting. METHODS: A retrospective study was performed on the charts of all patients taken care of by a physician-staffed prehospital mobile unit between June 2016 and September 2019 in Geneva. After approval by the ethics committee, charts were screened to identify all adult patients with a diagnosis of AHF in whom a prehospital arterial blood gas (ABG) sample was drawn. The main predictor was prehospital hypercapnia. The primary outcome was the admission rate in an acute care unit (ACU, composite of intensive care and high-dependency units). Secondary outcomes were ER length of stay (LOS), orientation from ER (intensive care unit, high-dependency unit, general ward, discharge home), intubation rate at 24 h, hospital LOS and hospital mortality. RESULTS: A total of 106 patients with a diagnosis of AHF were analysed. Hypercapnia was found in 61 (58%) patients and vital signs were more severely altered in this group. The overall ACU admission rate was 48%, with a statistically significant difference between hypercapnic and non-hypercapnic patients (59% vs 33%, p = 0.009). ER LOS was shorter in hypercapnic patients (5.4 h vs 8.9 h, p = 0.016). CONCLUSIONS: There is a significant association between prehospital arterial hypercapnia, acute care unit admission, and ER LOS in AHF patients.

Association between Prehospital Hypoxemia and Admission to Intensive Care Unit during the COVID-19 Pandemic: A Retrospective Cohort Study.

Background and Objectives: The aim of this study was to assess the association between prehospital peripheral oxygen saturation (SpO2) and intensive care unit (ICU) admission in confirmed or suspected coronavirus disease 19 (COVID-19) patients. Materials and Methods: We carried out a retrospective cohort study on patients requiring prehospital intervention between 11 March 2020 and 4 May 2020. All adult patients in whom a diagnosis of COVID-19 pneumonia was suspected by the prehospital physician were included. Patients who presented a prehospital confounding respiratory diagnosis and those who were not eligible for ICU admission were excluded. The main exposure was "Low SpO2" defined as a value < 90%. The primary outcome was 48-h ICU admission. Secondary outcomes were 48-h mortality and 30-day mortality. We analyzed the association between low SpO2 and ICU admission or mortality with univariable and multivariable regression models. Results: A total of 145 patients were included. A total of 41 (28.3%) patients had a low prehospital SpO2 and 21 (14.5%) patients were admitted to the ICU during the first 48 h. Low SpO2 was associated with an increase in ICU admission (OR = 3.4, 95% CI = 1.2-10.0), which remained significant after adjusting for sex and age (aOR = 5.2, 95% CI = 1.8-15.4). Mortality was higher in low SpO2 patients at 48 h (OR = 7.1 95% CI 1.3-38.3) and at 30 days (OR = 3.9, 95% CI 1.4-10.7). Conclusions: In our physician-staffed prehospital system, first low prehospital SpO2 values were associated with a higher risk of ICU admission during the COVID-19 pandemic.
