Perceived Hospital Preparedness Is Negatively Associated With Pandemic-Induced Psychological Vulnerability in Primary Care Employees: A Multicentre Cross-Sectional Observational Study.

OBJECTIVE: The COVID-19 pandemic had a profound negative impact on the psychological wellbeing of healthcare providers (HPs), but little is known about the factors that positively predict mental health of primary care staff during these dire situations. METHODS: We conducted an online questionnaire survey among 702 emergency department workers across 10 hospitals in Switzerland and Belgium following the first COVID-19 wave in 2020, to explore their psychological vulnerability, perceived concerns, self-reported impact and level of pandemic workplace preparedness. Participants included physicians, nurses, psychologists and nondirect care employees (administrative staff). We tested for predictors of psychological vulnerability through both an exploratory cross-correlation with rigorous correction for multiple comparisons and model-based path modelling. RESULTS: Findings showed that the self-reported impact of COVID-19 at work, concerns about contracting COVID-19 at work, and a lack of personal protective equipment were strong positive predictors of Depression, Anxiety, and Stress, and low Resilience. Instead, knowledge of the degree of preparedness of the hospital/department, especially in the presence of a predetermined contingency plan for an epidemic and training sessions about protective measures, showed the opposite effect, and were associated with lower psychological vulnerability. All effects were confirmed after accounting for confounding factors related to gender, age, geographical location and the role played by HPs in the hospital/department. CONCLUSIONS: Difficult working conditions during the pandemic had a major impact on the psychological wellbeing of emergency department HPs, but this effect might have been lessened if they had been informed about adequate measures for minimizing the risk of exposure.

Gender-based differential management of acute low back pain in the emergency department: A survey based on a clinical vignette.

BACKGROUND: Women may receive suboptimal pain management compared with men, and this disparity might be related to gender stereotypes. OBJECTIVES: To assess the influence of patient gender on the management of acute low back pain. DESIGN: We assessed pain management by 231 physicians using an online clinical vignette describing a consultation for acute low back pain in a female or male patient. The vignette was followed by a questionnaire that assessed physicians' management decisions and their gender stereotypes. METHODS: We created an online clinical vignette presenting a patient with acute low back pain and assessed the influence of a patient's gender on pain management. We investigated gender-related stereotyping regarding pain care by emergency physicians using the Gender Role Expectation of Pain questionnaire. RESULTS: Both male and female physicians tended to consider that a typical man was more sensitive to pain, had less pain endurance, and was more willing to report pain than a typical woman. These stereotypes did not translate into significant differences in pain management between men and women. However, women tended to be referred less often for imaging examinations than men and were also prescribed lower doses of ibuprofen and opioids. The physician's gender had a modest influence on management decisions, female physicians being more likely to prescribe ancillary examinations. CONCLUSION: We observed gender stereotypes among physicians. Our findings support the hypothesis that social characteristics attributed to men and women influence pain management. Prospective clinical studies are needed to provide a deeper understanding of gender stereotypes and their impact on clinical management.

Hypothermic cardiac arrest patients admitted to hospital who were not rewarmed with extracorporeal life support: A retrospective study.

Aims: Our goal was to study hypothermic cardiac arrest (CA) patients who were not rewarmed by Extracorporeal Life Support (ECLS) but were admitted to a hospital equipped for it. The focus was on whether the decisions of non-rewarming, meaning termination of resuscitation, were compliant with international guidelines based on serum potassium at hospital admission. Methods: We retrospectively included all hypothermic CA who were not rewarmed, from three Swiss centers between 1st January 2000 and 2nd May 2021. Data were extracted from medical charts and assembled into two groups for analysis according to serum potassium. We identified the criteria used to terminate resuscitation. We also retrospectively calculated the HOPE score, a multivariable tool predicting the survival probability in hypothermic CA undergoing ECLS rewarming. Results: Thirty-eight victims were included in the study. The decision of non-rewarming was compliant with international guidelines for 12 (33%) patients. Among the 36 patients for whom the serum potassium was measured at hospital admission, 24 (67%) had a value that - alone - would have indicated ECLS. For 13 of these 24 (54%) patients, the HOPE score was <10%, meaning that ECLS was not indicated. The HOPE estimation of the survival probabilities, when used with a 10% threshold, supported 23 (68%) of the non-rewarming decisions made by the clinicians. Conclusions: This study showed a low adherence to international guidelines for hypothermic CA patients. In contrast, most of these non-rewarming decisions made by clinicians would have been compliant with current guidelines based on the HOPE score.

[Pre-hospital red blood cells transfusions : Logistical aspects]. / Aspects logistiques de la transfusion de concentrés érythrocytaires en milieu préhospitalier.

Pre-hospital red blood cell transfusion is already used in many countries, both in military and civilian settings, and provides a better chance of survival for patients suffering from massive bleeding. However, this is not a current practice in Switzerland. This article aims to study Swiss specificities and provide a turnkey concept for the implementation of red blood cell transfusion in an emergency pre-hospital setting, by road or by air. The transfusion benefits and risks, the logistical aspect and the costs are discussed.

La transfusion de concentrés érythrocytaires (CE) en milieu préhospitalier est déjà réalisée dans de nombreux pays tant dans un contexte militaire que civil et permet d'augmenter les chances de survie des patients souffrant d'hémorragie massive. En Suisse, cette pratique n'est pas courante. Cet article a pour but d'étudier les spécificités suisses et de proposer un concept clé en main pour l'implémentation de la transfusion de CE dans un service de sauvetage médicalisé terrestre ou héliporté. Les bénéfices et les risques de la transfusion, les modalités logistiques et les coûts y sont abordés.

Opiophobia in Emergency Department Healthcare Providers: A Survey in Western Switzerland.

Opiophobia contributes to oligoanalgesia in the emergency department (ED), but its definition varies, and its association to healthcare providers' personality traits has been scantly explored. Our purpose was to study the different definitions of opiophobia and their association with two personality traits of doctors and nurses working in EDs, namely the stress from uncertainty and risk-taking. We used three online questionnaires: the 'Attitude Towards Morphine Use' Score (ATMS), the Stress From Uncertainty Scale (SUS) and the Risk-Taking Scale (RTS). Doctors and nurses from nine hospital EDs in francophone Switzerland were invited to participate. The ATMS score was analyzed according to demographic characteristics, SUS, and RTS. The response rate was 56%, with 57% of respondents being nurses and 63% women. Doctors, less experienced and non-indigenous participants had a significantly higher ATMS (all p ≤ 0.01). The main contributors of the ATMS were the fear of side effects and of addiction. In multivariate analysis, being a doctor, less experience and non-indigenous status were predictive of the ATMS; each point of the SUS increased the ATMS by 0.24 point. The fear of side effects and of addiction were the major contributors of opiophobia among ED healthcare providers; opiophobia was also associated with their personality traits.

Vital Signs in Accidental Hypothermia.

Pasquier, Mathieu, Evelien Cools, Ken Zafren, Pierre-Nicolas Carron, Vincent Frochaux, and Valentin Rousson. Vital signs in accidental hypothermia. High Alt Med Biol. 22: 142-147, 2021. Background: Clinical indicators are used to stage hypothermia and to guide management of hypothermic patients. We sought to better characterize the influence of hypothermia on vital signs, including level of consciousness, by studying cases of patients suffering from accidental hypothermia. Materials and Methods: We retrospectively included patients aged ≥18 years admitted to the hospital with a core temperature below 35°C. We identified the cases from a literature review and from a retrospective case series of hypothermic patients admitted to the hospital between 1994 and 2016. Patients who experienced cardiac arrest, as well as those with potential confounders such as concomitant diseases or intoxications, were excluded. Relationships between core temperature and heart rate, systolic blood pressure, respiratory rate, and level of consciousness were explored via correlations and regression. Results: Of the 305 cases reviewed, 216 met the criteria for inclusion. The mean temperature was 29.7°C ± 4.2°C (range 19.3°C-34.9°C). The relationships between temperature and each of the four vital signs were generally linear and significantly positive, with Spearman correlations for respiratory rate, heart rate, systolic blood pressure, and Glasgow Coma Score (GCS) of 0.29 (p = 0.024), 0.44 (p < 0.001), 0.47 (p < 0.001), and 0.78 (p < 0.001), respectively. Based on linear regression, the mean decrease of a vital sign associated with a 1°C decrease of temperature was estimated to be 0.50 minute-1 for respiratory rate, 2.54 minutes-1 for heart rate, 4.36 mmHg for systolic blood pressure, and 0.88 for GCS. Conclusions: There is a significant positive correlation between core temperature and heart rate, systolic blood pressure, respiratory rate, and GCS. The relationship between vital signs and temperature is generally linear. This knowledge might help clinicians make appropriate decisions when determining whether the clinical condition of a patient should be attributed to hypothermia. This could enhance clinical care and help to guide future research.

[Facial and orbital emphysema after blowing : a review]. / Emphysème facial et intra-orbitaire après mouchage : revue de la littérature.

Facial and orbital emphysema without any trauma is an uncommon condition that might occur after nose blowing or sneezing efforts. It is usually self-limited and resolves spontaneously within two weeks. Surgical treatment is only reserved in case of complications such as neurological deficiencies or infection of the ocular globe. We report the case of a 42 year-old patient presenting a right spontaneous facial and orbital emphysema following nose blowing, treated by conservative measures, with a systematic review of the literature.

L'emphysème facio-orbitaire atraumatique est un phénomène peu commun pouvant se produire lors du mouchage ou d'éternuements. Il est habituellement contenu et d'évolution spontanément régressive en 2 semaines. Une indication à un traitement chirurgical est réservée en cas de complications telles qu'un déficit neuro-ophtalmique ou une infection du globe oculaire. Nous présentons le cas d'un patient de 42 ans sans antécédent de traumatisme craniofacial, se présentant aux urgences avec un important emphysème facial et intra-orbitaire à droite, spontané survenu lors du mouchage, et traité de manière conservative, ainsi qu'une revue de la littérature.

S100B Blood Level Determination for Early Management of Ski-Related Mild Traumatic Brain Injury: A Pilot Study.

Background: Mild traumatic brain injury (mTBI) management in emergency departments is a complex process involving clinical evaluation, laboratory testing, and computerized tomography (CT) scanning. Protein S100B has proven to be a useful blood biomarker for early evaluation of mTBI, as it reduces the required CT scans by one-third. However, to date, the ability of S100B to identify positive abnormal findings in the CT scans of patients suffering from mTBI caused by ski practice has not been investigated. Thus, the primary aim of this study was to investigate the diagnostic performance of S100B as an mTBI management biomarker in patients with ski-related mTBI. Materials and Methods: One hundred and thirty adult mTBI patients presenting to the emergency department of Hôpital du Valais in Sion, Switzerland, with a Glasgow Coma Scale (GCS) score of 13-15 and clinical indication for a CT scan were included in the study. Blood samples for S100B measurement were collected from each patient and frozen in 3-hour post-injury intervals. CT scans were performed for all patients. Later, serum S100B levels were compared to CT scan findings in order to evaluate the biomarker's performance. Results: Of the 130 included cases of mTBI, 87 (70%) were related to ski practice. At the internationally established threshold of 0.1 µg/L, the receiver operating characteristic curve of S100B serum levels for prediction of abnormal CT scans showed 97% sensitivity, 11% specificity, and a 92% negative predictive value. Median S100B concentrations did not differ according to sex, age, or GCS score. Additionally, there was no significant difference between skiers and non-skiers. However, a statistically significant difference was found when comparing the median S100B concentrations of patients who suffered fractures or had polytrauma and those who did not suffer fractures. Conclusion: The performance of S100B in post-mTBI brain lesion screenings seems to be affected by peripheral lesions and/or ski practice. The lack of neurospecificity of the biomarker in this context does not allow unnecessary CT scans to be reduced by one-third as expected.

Avalanche victims in cardiac arrest are unlikely to survive despite adherence to medical guidelines.

AIMS: Our goals were to describe and analyse the medical management and clinical course of avalanche victims in cardiac arrest (CA), focusing on adherence to international recommendations on avalanche victims in CA regarding critical decisions. METHODS: We retrospectively included all avalanche victims with CA from 1st January 2004 to 1st June 2016 in a single physician-staffed alpine helicopter emergency medical service. Data regarding cardiopulmonary resuscitation (CPR), transportation to hospital whilst undergoing CPR, and extracorporeal life support rewarming (ECLSR) for patients still in CA at hospital admission were abstracted from the prehospital and medical health records. RESULTS: Sixty-six victims were included in this study; 31 (47%) were declared dead on scene. Of the remaining 35 victims, 7 (20%) had prehospital return of spontaneous circulation (ROSC), 28 (80%) were transported whilst undergoing CPR, 3 had hospital ROSC and 7 (28%) of the 25 patients with persistent CA at hospital underwent ECLSR. The medical management comprised 126 documented critical decisions, corresponding to guidelines in 117 (93%) decisions. None of the 66 studied patients survived to hospital discharge, and 7 (11%) were organ donors. CONCLUSIONS: The management of avalanche victims in CA respect current guidelines regarding the critical decisions, but no patient survived in this sample. The presence of a few cases with incorrect management and potential undertreatment suggests some room for improvement.

Indications and Outcomes of Helicopter Rescue Missions in Alpine Mountain Huts: A Retrospective Study.

Pasquier, Mathieu, Louis Marxer, Hervé Duplain, Vincent Frochaux, Florence Selz, Pierre Métrailler, Grégoire Zen Ruffinen, and Olivier Hugli. Indications and outcomes of helicopter rescue missions in alpine mountain huts: A retrospective study. High Alt Med Biol 18:355-362, 2017. AIMS: This retrospective study describes the rescue indications and outcome of patients rescued by helicopter from mountain huts in the Swiss Alps. The hospital course and operational data were also studied. RESULTS: Among 14,872 helicopter rescue missions undertaken during the 10-year study period, 309 (2.1%) were performed from mountain huts at a mean altitude of 2794 ± 459 m. The mean age of the patients was 43 ± 16 and 66% were male. Thirty-four percent of the patients had a National Advisory Committee for Aeronautics score ≥3. Most (89%) patients were transported to hospital and only 12 (3.9%) patients had to stay more than 48 hours. Hospital diagnoses were extremely varied. Trauma accounted for 50% and altitude diseases for 7% of the cases. A winching procedure was performed 18 times and 19 missions included a night flight. CONCLUSIONS: Helicopter rescue missions in mountain huts are a small part of all rescue missions. Our study provides a better understanding of medical emergencies arising in mountain huts. The diagnoses encountered are extremely varied in their type and severity. Hut keepers should be prepared for these situations as they will often have to act as first responders in the case of medical problems.

[Benefit of ultrasound in the early management of patients in shock]. / Apport de l'echographie dans la prise en charge initiate des patients en etat de choc.

Shock is a hemodynamic situation that aggravates the vital prognostic of every patient regardless of the underlying pathology. It has been well documented that the speed at which hemodynamics is restored to standard values significantly decreases the mortality and morbidity in these patients. Initially described in traumatology, then in every type of shock, the contribution of ultrasonography performed at the bedside by the physician in charge allows for a significant shortening of the diagnostic procedure and thus an earlier start for a goal-directed treatment.

[When should a patient with low back pain/sciatica be referred to the emergency ward?]. / Quand référer aux urgences un patient présentant une lombalgie/ lombosciatalgie aiguë?

Low back pain and sciatica are common causes of medical consultation. The medical history and the physical examination are essential in their management. The primary care physician initiates treatment and relies on his physical examination to identify "red flags" that require further investigations. Regarding sciatica, it is essential to identify 3 clinical entities that require prompt referral to the emergency department for prompt neurosurgical management. These include hyperalgic sciatica, sciatica with motor deficits and the cauda equina syndrome. Sciatica with sensory deficits do not require emergency department referral.
