Objectives: Primary care treatable visits in the Emergency Department (ED) are part of the different factors leading to the overcrowding. Their triage and diversion to alternative care centers could potentially help manage the increasing inflow provided the establishment of an advanced triage to ensure patients' safety. We aim to suggest a new triage tool, PERSEE, and prove its feasibility, safety and performance., Methods: All self-referrals presented to the ED were triaged with the PERSEE algorithm: first, patients were classified with a five-level ED acuity scale and then evaluated by algorithms to determine their appropriate category (ED or Primary Care). Patients were eligible for a redirection if they were triaged by the acuity scale as level 3 or lower, considered as ambulatory patients and finally categorized as primary care patients. We defined appropriate redirections as patients requiring less than three emergency resources, no emergency-specific treatment and no hospitalization., Results: During the study, 1999 patients were admitted to the ED. Among those, 1333 patients were self-referred (66.9%) of whom 1167 patients were triaged as level 3 or below (58.6%) and 775 patients triaged as ambulatory (39.0%). Among the 775 patients, 200 patients were categorized as primary care treatable (10.0%) and thereby, as potentially eligible for a redirection. We noticed an error rate of 7%, sensitivity of 24.06% and specificity of 97.6%. The redirection rate reached 15% of the self-referrals., Conclusion: These results indicate that PERSEE triage could lead to a safe redirection and could be an efficient tool to reduce ED crowding provided several adjustments.

Objectives: Due to the persistent primary care physicians shortage and the substantial increase in their workload, the organization of primary care calls during out-of-hours periods has become an everyday challenge. The SALOMON algorithm is an original nurse telephone triage tool allowing to dispatch patients to the best level of care according to their conditions. This study evaluated its reliability and criterion validity in rea-life settings., Methods: In this 5-year study, out-of-hours primary care calls were dispatched into four categories: Emergency Medical Services Intervention (EMSI), Emergency Department referred Consultation (EDRC), Primary Care Physician Home visit (PCPH), and Primary Care Physician Delayed visit (PCPD). We included data of patients' triage category, resources, and destination. Patients included into the primary care cohort were classified undertriaged if they had to be redirected to an emergency department (ED). Patients from the ED cohort were considered overtriaged if they did not require at least three diagnostic resources, one emergency-specific treatment or any hospitalization. In the ED cohort, only patients from the University Hospitals were considered., Results: 10,207 calls were triaged using the SALOMON tool: 19.2% were classified as EMSI, 15.8% as EDRC, 62.8% as PCPH, and 2.2% as PCPD. The triage was appropriate for 85.5% of the calls with a 14.5% overtriage rate. In the PCPD/PCPH cohort, 96.9% of the calls were accurately triaged and 3.1% were undertriaged. SALOMON sensitivity and specificity reached 76.6% and 98.3%, respectively., Conclusion: SALOMON algorithm is a valid triage tool that has the potential to improve the organization of out-of-hours primary care work.

Background: The role played by large-scale repetitive SARS-CoV-2 screening programs within university populations interacting continuously with an urban environment, is unknown. Our objective was to develop a model capable of predicting the dispersion of viral contamination among university populations dividing their time between social and academic environments., Methods: Data was collected through real, large-scale testing developed at the University of Liège, Belgium, during the period Sept. 28th-Oct. 29th 2020. The screening, offered to students and staff (n = 30,000), began 2 weeks after the re-opening of the campus but had to be halted after 5 weeks due to an imposed general lockdown. The data was then used to feed a two-population model (University + surrounding environment) implementing a generalized susceptible-exposed-infected-removed compartmental modeling framework., Results: The considered two-population model was sufficiently versatile to capture the known dynamics of the pandemic. The reproduction number was estimated to be significantly larger on campus than in the urban population, with a net difference of 0.5 in the most severe conditions. The low adhesion rate for screening (22.6% on average) and the large reproduction number meant the pandemic could not be contained. However, the weekly screening could have prevented 1393 cases (i.e. 4.6% of the university population; 95% CI: 4.4-4.8%) compared to a modeled situation without testing., Conclusion: In a real life setting in a University campus, periodic screening could contribute to limiting the SARS-CoV-2 pandemic cycle but is highly dependent on its environment., (© 2022.

Objectives: Since the beginning of the novel coronavirus outbreak, different strategies have been explored to stem the spread of the disease and appropriately manage patient flow. Triage, an effective solution proposed in disaster medicine, also works well to manage Emergency Department (ED) flow. The aim of this study was to describe the role of an ED Triage Center for patients with suspected novel coronavirus disease (Covid-19) and characterize the patient flow., Methods: In March 2020, we established a Covid-19 triage center close to the Liège University EDs. From March 2 to March 23, we planned to analyze the specific flow of patients admitted to this triage zone and their characteristics in terms of inner specificities, work-up and management. During this period, all patients presented to the ED with symptoms suggestive of Covid-19 were included in the study., Results: A total amount of 1071 patients presented to the triage center during the study period. 41.50% of the patients presented with flu-like symptoms. In 82.00% of the cases, no risk factor of virus transmission was found. The SARS-Cov2 positive patients represented 29.26% of the screened patients. 83.00% of patients were discharged home while 17.00% were admitted to the hospital., Conclusion: Our experience suggests that triage centers for the assessment and management of Covid-19 suspected patients is an essential key strategy to prevent the spread of the disease among non-symptomatic patients who present to the EDs for care. This allows for a disease-centered work-up and safer diversion of Covid-19 patients to specific hospital units.

Background: The COVID-19 pandemic has imposed significant challenges on hospital capacity. While mitigating unnecessary crowding in hospitals is favourable to reduce viral transmission, it is more important to prevent readmissions with impaired clinical status due to initially inappropriate level of care. A validated predictive tool to assist clinical decisions for patient triage and facilitate remote stratification is of critical importance., Methods: We conducted a retrospective study in patients with confirmed COVID-19 stratified into two levels of care, namely ambulatory care and hospitalization. Data on socio-demographics, clinical symptoms, and comorbidities were collected during the first ( N  = 571) and second waves ( N  = 174) of the pandemic in Belgium (2 March to 6 December 2020). Univariate and multivariate logistic regressions were performed to build and validate the prediction model., Results: Significant predictors of hospitalization were old age (OR = 1.08, 95%CI:1.06-1.10), male gender (OR = 4.41, 95%CI: 2.58-7.52), dyspnoea (OR 6.11, 95%CI: 3.58-10.45), dry cough (OR 2.89, 95%CI: 1.54-5.41), wet cough (OR 4.62, 95%CI: 1.93-11.06), hypertension (OR 2.20, 95%CI: 1.17-4.16) and renal failure (OR 5.39, 95%CI: 1.00-29.00). Rhinorrhea (OR 0.43, 95%CI: 0.24-0.79) and headache (OR 0.36, 95%CI: 0.20-0.65) were negatively associated with hospitalization. A receiver operating characteristic (ROC) curve was constructed and the area under the ROC curve was 0.931 (95% CI: 0.910-0.953) for the prediction model (first wave) and 0.895 (95% CI: 0.833-0.957) for the validated dataset (second wave)., Conclusion: With a good discriminating power, the prediction model might identify patients who require ambulatory care or hospitalization and support clinical decisions by Emergency Department staff and general practitioners.

Objectives : For years, general practitioners (GP) shortage and patients' increasing demand for acute care have been associated with Emergency Department (ED) crowding. Indeed, EDs admissions for non-emergency care seem to constantly increase. Surprisingly, the rationale for patients own decision to directly reach EDs over primary care have been poorly investigated to date. Methods : We conducted a study on patients admitted in two University EDs during nine consecutive days. Patients were asked to answer a survey about their frames for coming and if they were self-referred, referred by a GP, a specialist or after calling the Emergency Number. Results : During the study period, 68.0% of patients were self-referred, 17.0% referred by their GP, 8.5% by a specialist and 7% after an emergency call. 51.0% of the self-referrals thought EDs were the appropriate location to deal with their health problem and 24.0% because of a better accessibility. We noticed that 15.0% of the incomings looked for specialized care and 4.22% reported that the stress had motivated them. Of note, 4.6% of the patients were attracted by the hospital reputation. Financial concerns represented less than 1.0% of the motives invocated. Conclusion : We found that patients' self-perceived severity of illness is the predominant frame to each the ED when they face needs for acute care. EDs' accessibility as compared with other facilities also seems to encourage patients to come to the ED. Other factors such as the hospital reputation or patients' stress tend to influence ED attendance but to a much lesser extent.

Background: The coronavirus infectious disease 19 (COVID-19) pandemic has resulted in significant morbidities, severe acute respiratory failures and subsequently emergency departments' (EDs) overcrowding in a context of insufficient laboratory testing capacities. The development of decision support tools for real-time clinical diagnosis of COVID-19 is of prime importance to assist patients' triage and allocate resources for patients at risk., Methods and Principal Findings: From March 2 to June 15, 2020, clinical patterns of COVID-19 suspected patients at admission to the EDs of Liège University Hospital, consisting in the recording of eleven symptoms (i.e. dyspnoea, chest pain, rhinorrhoea, sore throat, dry cough, wet cough, diarrhoea, headache, myalgia, fever and anosmia) plus age and gender, were investigated during the first COVID-19 pandemic wave. Indeed, 573 SARS-CoV-2 cases confirmed by qRT-PCR before mid-June 2020, and 1579 suspected cases that were subsequently determined to be qRT-PCR negative for the detection of SARS-CoV-2 were enrolled in this study. Using multivariate binary logistic regression, two most relevant symptoms of COVID-19 were identified in addition of the age of the patient, i.e. fever (odds ratio [OR] = 3.66; 95% CI: 2.97-4.50), dry cough (OR = 1.71; 95% CI: 1.39-2.12), and patients older than 56.5 y (OR = 2.07; 95% CI: 1.67-2.58). Two additional symptoms (chest pain and sore throat) appeared significantly less associated to the confirmed COVID-19 cases with the same OR = 0.73 (95% CI: 0.56-0.94). An overall pondered (by OR) score (OPS) was calculated using all significant predictors. A receiver operating characteristic (ROC) curve was generated and the area under the ROC curve was 0.71 (95% CI: 0.68-0.73) rendering the use of the OPS to discriminate COVID-19 confirmed and unconfirmed patients. The main predictors were confirmed using both sensitivity analysis and classification tree analysis. Interestingly, a significant negative correlation was observed between the OPS and the cycle threshold (Ct values) of the qRT-PCR., Conclusion and Main Significance: The proposed approach allows for the use of an interactive and adaptive clinical decision support tool. Using the clinical algorithm developed, a web-based user-interface was created to help nurses and clinicians from EDs with the triage of patients during the second COVID-19 wave., Competing Interests: The authors have declared that no competing interests exist.

The regulation of the unscheduled care takes part of the different methods engaged to better organize the global demand for unscheduled urgent care among the different levels of care. Indeed, the first level of care equally with the emergency departments are facing major patient inflows often exceeding their available resources. Technological advances in healthcare and spreading of medical information reveal themselves as precursors of new adaptive strategies and daily challenges. The creation of an interactive app for patients self-triage through the different levels of care involves those different concepts. We created a new interactive platform, the ODISSEE mobile application (Outil Décisionnel et Informatif des Structures de Soins Efficientes Existantes), to allow patient's self-triage to the best level of care. The protocols used were directly based on a previously validated tool with a 5-year experience in our institution, the SALOMON algorithm (Système Algorithmique Liégeois d'Orientation pour la Médecine Omnipraticienne Nocturne). Establishment of interactive self-triage platform to guide patients to the best level of care could potentially be a promising tool to improve the regulation of unscheduled urgent care.

Moyamoya disease is a rare cerebral vasculopathy. Disease onset is mainly sudden presenting as an ischemic stroke but also sometimes as a brain hemorraghe. Cerebral angiography is the gold standard to confirm the diagnosis. Different therapeutic approaches have been described such as conservative management or endoscopic and surgical approaches. We report the case of a young patient who was diagnosed with a brain hemorraghe following a sudden loss of consciousness.

Facing the aging of primary care practitioners and their still increasing duties, we implemented a new and original solution to maintain the continuity of primary care in the area surrounding of our university hospital. Thereby, we created a new model of nurse telephone triage for the regulation of out-of-hours primary care calls, the SALOMON algorithm ("Système Algorithmique Liégeois d'Orientation pour la Médecine Omnipraticienne Nocturne"). Following the nurse telephone triage and the assessment of the illness severity, the patient is referred to four potential orientations : Emergency Medical Services (EMS), Emergency Department Referred Consultation (EDRC), Primary Care Physician Home visit (PCPH) and Primary Care Physician Delayed visit (PCPD). In this article, we aim to describe the SALOMON model and present a 12-month feasibility study in order to determine the safety of the tool. We can also notice nurse and general practitioner satisfaction about this approach with a positive impact on the global primary care out-of-hour organization. Currently, SALOMON seems to be full of promise. Further investigations on a larger cohort are needed to determine more precisely the reliability of the algorithm.

Heart transplantation remains undoubtedly the most effective treatment for end-stage heart failure, whatever its cause. Last decade has witnessed significant improvements in terms of morbidity and mortality following heart transplant. The 5-year survival rate is now beyond 70 %. However, the shortage of potential donors limits its use and requires strict criteria before listing a candidate for heart transplantation. Herein, we present a review of current indications and results of the heart transplantation program at the University hospital of Liège.

In March 2020, the COVID-19 pandemic started to spread among the Belgian territory. Our university hospital was confronted to the very need of specific reorganizations guided by the implementation of the Hospital Emergency Plan.This article aims to describe the experience of the University Hospital of Liège (CHU Liège) during the COVID-19 outbreak and demonstrates the efficiency of advanced triage centers to regulate hospital admissions from the emergency department (ED)., Methods: since the beginning of March 2020, the CHU of Liège has implemented specific advanced triage centers to manage patients with SARS-CoV-2 suspected symptoms. The first center was organized inside the hospital but the need of outside structures led to the creation of two centers by the end of March. From March 2 to May 3, data from the different visits at the COVID-19 centers were collected (numbers of admissions, rationale for coming, work up and outcome)., Results: during the study period, 3,094 patients were admitted to the specific COVID-19 centers of the CHU Liège. This represents 3,431 visits among which 337 were classified as readmission visits. The sensitivity and specificity of the triage centers to determine the need for hospitalization were, respectively, estimated at 87,9 % and 93,4 %., Conclusion: our experience tends to demonstrate the role of specific COVID-19 triage centers located very close to the EDs aimed at managing COVID-19 suspected patients in order to actually determine their need for subsequent hospitalization.

Parsonage-Turner syndrome, also known as neuralgic amyotrophy, is a rare disorder characterized by painful clinical manifestations mainly involving the upper limbs. This syndrome seems to be triggered, among other factors, by some viral infections, although its pathophysiology remains unclear. Moreover, it has rarely been related to hepatitis E virus infection. We report the case of a 33-year-old man who was diagnosed with Parsonage-Turner syndrome following acute hepatitis E infection., Learning Points: Parsonage-Turner syndrome is a painful and disabling condition.Hepatitis E infection can lead to extra-hepatic manifestations such as neurological complications.The association of Parsonage-Turner syndrome with hepatitis E infection is rare but some cases have been reported previously in the literature., Competing Interests: Conflicts of Interests: The Authors declare that there are no competing interest

Background: The Trauma-Induced Coagulopathy Clinical Score (TICCS) was developed to be calculable on the site of injury to discriminate between trauma patients with or without the need for damage control resuscitation and thus transfusion. This early alert could then be translated to in-hospital parameters at patient arrival. Base excess (BE) and ultrasound (FAST) are known to be predictive parameters for emergent transfusion. We emphasize that adding these two parameters to the TICCS could improve the scoring system predictability., Methods: A retrospective study was conducted in the University Hospital of Liège. TICCS was calculated for every patient. BE and FAST results were recorded and points were added to the TICCS according to the TICCS.BE definition (+ 3 points if BE < - 5 and + 3 points in case of a positive FAST). Emergent transfusion was defined as the use of at least one blood product in the resuscitation room. The capacity of the TICCS, the TICCS.BE and the Trauma-Associated Severe Hemorrhage (TASH) to predict emergent transfusion was assessed., Results: A total of 328 patients were included. Among them, 14% needed emergent transfusion. The probability for emergent transfusion grows with the TICCS and the TICCS.BE values. We did not find a significant difference between the TICCS (AUC 0.73) and the TICCS.BE (AUC 0.76). The TASH proved to be more predictive (AUC 0.89). 66.6% of the patients with a TICCS ≥ 10 and 81.5% with a TICCS.BE ≥ 14 required emergent transfusion., Conclusion: Adding BE and FAST to the original TICCS does not significantly improve the scoring system predictability. A prehospital TICCS > 10 could be used as a trigger for emergent transfusion activation. TASH could then be used at hospital arrival. Prehospital TASH calculation may be possible but should be further investigated., Level of Evidence: Diagnostic test, level III.

We report a case of left ventricular pseudo-aneurysm and we take the opportunity to briefly review the literature concerning etiologies, diagnosis and management of this pathology, emphasizing some differences with the true aneurysm.

Background: Management of the increasing number of sensitized heart transplant candidates has become a recurrent issue. Rather than using pretransplant desensitization therapies, we used a posttransplant prophylactic strategy. Our aim was to describe outcomes in transplant recipients with preformed donor-specific anti-HLA antibodies (pfDSA) managed with this strategy., Methods: A posttransplant protocol was applied to patients transplanted with pfDSA, consisting of perioperative management of DSA (polyvalent immunoglobulins +/- perioperative plasmapheresis sessions, according to DSA level, as well as induction therapy) and systematic treatment of subsequent antibody-mediated rejection (AMR), even when subclinical. We performed a retrospective analysis of this prospective protocol. The study included all consecutive first recipients of a noncombined heart transplant performed between 2009 and 2015 at our center. The primary endpoint was all-cause mortality. Secondary endpoints included primary graft dysfunction, early posttransplant bleeding, rejection, and cardiac allograft vasculopathy-free survival., Results: A total of 523 patients were studied, including 88 (17%) and 194 (37%) transplanted with DSA mean fluorescence intensity (MFI) of 500 to 1000 and greater than 1000, respectively. The median follow-up period was 4.06 years. Survival was not significantly different between groups. Rejection-free survival was worse in patients with pfDSA MFI >1000, evidenced by a fourfold increase in the risk of antibody-mediated rejection. The incidence of primary graft dysfunction and cardiac allograft vasculopathy-free survival did not significantly differ between groups. Perioperative plasmapheresis increased the risk for transfusion of packed red blood cells., Conclusions: This exclusively posttransplant prophylactic strategy achieved favorable outcomes in heart transplant recipients with pfDSA.

Introduction: Triage systems for out-of-hours primary care physician (PCP) calls have been implemented empirically but no triage algorithm has been validated to date. A triage algorithm named SALOMON (Système Algorithmique Liégeois d'Orientation pour la Médecine Omnipraticienne Nocturne) was developed to guide triage nurses. This study assessed the performance of the algorithm using simulated PCP calls. Methods: Ten nurses were involved in 130 simulated PCP call scenarios, allowing the determination of SALOMON's inter-rater agreement by comparing the actual choices of a specific triage flowchart and the level of care selected as compared with reference assignments. Intra-rater agreement was estimated by comparing triage after training (T1) and 3 to 6 months after SALOMON use in clinical practice (T2). Results: Overall selection of flowcharts was accurate for 94 .1% of scenarios at T1 and 98.7% at T2. Level of triage was adequate for 93.4% of scenarios at T1 and 98.5% at T2. Both flowchart and triage level accuracy improved significantly from T1 to T2 ( p  < 0.0001). SALOMON algorithm use is associated with a 0.97/0.99 sensitivity and 0.97/0.99 specificity, at T1/T2 respectively. Conclusions: Results revealed that using the SALOMON algorithm is valid for out-of-hours PCP calls triage by nurses. The criterion validity of this algorithm should be further evaluated through its implementation in a real life setting.

Background: Heart transplantation (HT) from donation after circulatory death (DCD) has yet to achieve wide clinical application despite the encouraging resultsreported recently. In this study we describe 2 cases of successful adult DCD HT performed at our institution using an original protocol., Methods: Our local abdominal DCD protocol was updated to allow DCD heart procurement, and was accepted by the institutional ethics committee. The main features of the protocol include: pre-mortem insertion of peripheral venoarterial extracorporeal membrane oxygenation cannulas; thoracoabdominal normothermic regional perfusion (NRP) by clamping the 3 aortic arch vessels to exclude cerebral circulation; and in-situ heart resuscitation. The retrieved hearts were directly transplanted into recipients located in an adjoining operating room., Results: The procurement warm ischemic time was 25 minutes for the first donor, and 26 minutes for the second donor. The cold ischemic time was 16 minutes for the first recipient and 17 minutes for the second recipient. The suture time was 30 minutes for the first recipient, and 53 minutes for the second recipient. Both recipients were easily weaned off cardiopulmonary bypass in sinus rhythm and inotropic support. Post-operative evaluation of cardiac function was excellent and the patients were subsequently discharged home., Conclusions: Transplantation of hearts from DCD donors is now a clinical reality.NRP is a useful tool for resuscitation, reperfusion, and preservation of transplanted hearts. It also offers the opportunity to assess the function and viability of organs before transplantation. However,due to ethical issues, some may object to ante-mortem intervention., (Copyright © 2019 International Society for Heart and Lung Transplantation. Published by Elsevier Inc.

Background: The evidence of the Trauma Induced Coagulopathy Clinical Score (TICCS) accuracy has been evaluated in several studies but the potential effect of its use on patient outcomes needs to be evaluated. The primary objective of this study is to evaluate the impact on mortality of a prehospital discrimination between trauma patients with or without a potential need for damage control resuscitation., Methods: The trial will be designed as randomized phase II clinical trial with comparison of the experimental protocol against the standard of care. The TICCS will be calculated on the site of injury for the patients of the intervention group and treatment will be guided by the TICCS value. Seven days mortality, 30 days mortality, global use of blood products and global hospital length-of-stay will be compared., Discussion: Many data suggest that a very early flagging of trauma patients in need for DCR would be beneficial but this need to be proved. Do we improve our quality of care by an earlier diagnosis? Does a prehospital discrimination between trauma patients with or without a potential need for DCR has a positive impact?

Introduction Evidence supporting the use of Thromboelastography (TEG®) and rotational thromboelastometric (ROTEM®) in the trauma setting remains limited. We present the results of a practical evaluation of the potential interest of ROTEM® in the diagnosis of acute coagulopathy and the need for emergent blood product transfusion in the general trauma population of a non-trauma Belgian emergency department. Methods Extracting a convenience cohort from the initial prospective TICCS study, we performed a retrospective analysis to test the following hypothesis: ROTEM® might be helpful to discriminate trauma patients with or without acute coagulopathy. Fifty patients were included and ROTEM® results were compared to conventional coagulation tests results, blood transfusion need and outcome. Results With a negative predictive value of 97.6% and a positive predictive value of 42.9%, a strictly normal ROTEM® profile at the time of admission seems to be able to exclude the presence of acute coagulopathy. ROTEM® also seems to be accurate in identifying patients without the need for emergent blood product transfusions. Conclusion In a population of trauma patients of a Belgian general emergency department, a strictly normal coagulation profile evaluated by ROTEM® at hospital entry is associated with a normal coagulation profile evaluated by INR and fibrinogen levels and the absence of any indication of blood product transfusion. ROTEM® may be useful for preselection of trauma patients at risk for coagulopathy within the global trauma population. This, however, would need confirmation in further investigations., Trial Registration: clinicaltrials.gov NCT02132208 Registered 6 May 2014.

To cope with overcrowding, a consequence of their constant growth, emergency departments have implemented operational strategies based on triage systems. Despite its interest, nurse triage has been limited by several hindrances, and new strategies are emerging. Among those, advanced nurse triage, allowing a nurse to initiate the diagnostic process just after categorization of the patient, seems to be promising. A study on advanced nurse triage for patients presenting with chest pain has been conducted in the emergency department of the CHU of Liège. The encouraging results obtained following this new system demonstrate a reduction of the delay to management of patients, and a reduction of the total length of stay in the emergency unit mainly during overcrowding periods. Advanced nurse triage, in addition to a conventional triage during overcrowding periods, improves management of patients in terms of time and reduces the total time spent in the emergency department.

Pulmonary embolism (PE) is the third most common cardiovascular disease in industrialized countries. Multiple clinical presentations and non-specific symptoms lead to frequents misdiagnosis. Using and plan therapeutic and admission versus discharge strategies.

Acute heart failure is a common cause of admission in emergency department. Management requires rapid support when haemodynamic or respiratory parameters are altered. Identifying enabling factors and their specific treatment is an integral part of management. The most common clinical presentation is volume overload, whose treatment remains the combination of diuretics and vasodilators. In case of impaired perfusion, various inotropic supports may be considered, but also more and more circulatory assistance devices.

The endothelium plays a vital role as part of the cardiovascular continuum. Risk factors such as hypertension and dyslipidemia unbalance angiotensin II - bradykinin homeostasis, leading to endothelial dysfunction and changes in vascular structure that promote atherosclerosis and thrombosis. When dealing with risk factors, treatment should focus on the prevention and restoration of endothelial function. Not all cardiovascular drugs are able to reverse vascular and structural endothelial dysfunction. Increasing levels of bradykinin is an effect of the use of angiotensin-converting enzyme inhibitors (ACE-Is), and also a fundamental part of their mode of action. The cardiovascular protection observed with ACE-I, and not with sartans, can be explained rationally by the specific effects of bradykinin on the endothelium. In the pharmacological class of ACE-Is, perindopril likely produces the strongest effects on bradykinin, which may explain, at least in part, the documented superiority of this drug in the prevention and treatment of cardiovascular disease.

Background: Identifying trauma patients that need emergent blood product transfusion is crucial. The Trauma Induced Coagulopathy Clinical Score (TICCS) is an easy-to-measure score developed to meet this medical need. We hypothesized that TICCS would assist in identifying patients that need a transfusion in a large cohort of severe trauma patients from the TraumaRegister DGU ® (TR-DGU)., Materials and Methods: A total of 33,385 severe trauma patients were extracted from the TR-DGU for retrospective analysis. The TICCS was adapted for the registry structure. Blood transfusion was defined as the use of at least one unit of red blood cells (RBC) during acute hospital treatment., Results: With an area under the receiving operating curve (AUC) of 0.700 (95% CI: 0.691-0.709), the TICCS appeared to be moderately discriminant for determining the need for RBC transfusion in the trauma population of the TR-DGU. A TICCS cut-off value of ≥12 yielded the best trade-off between true positives and false positives. The corresponding positive predictive value and negative predictive values were 48.4% and 89.1%, respectively., Conclusion: This retrospective study confirms that the TICCS is a useful and simple score for discriminating between trauma patients with and without the need for emergent blood product transfusion.

Transdiaphragmatic peritoneopericardial hernia is a rare complication after peritoneopericardial window formation, coronary artery bypass grafting using the gastroepiploic artery, or subxiphoid epicardial pacemaker insertion. We describe two different clinical presentations of transdiaphragmatic peritoneopericardial hernia in patients who had undergone recent heart transplantation. One was an exceptional case of cardiac tamponade caused by small bowel strangulation through a diaphragmatic defect.

Numerous epidemiological studies have shown that a high resting heart rate is associated with an increased cardiovascular morbidity and mortality, particularly in heart failure. The resting heart rate is not only a risk marker in heart failure, but it is also a risk factor, i.e., modifying heart rate also modifies the risk. Chronotropic drugs have shown benefits in terms of morbidity and mortality. Nevertheless, there is a major difference between the recommended heart rate and the patients’ everyday life heart rate. Indeed, even if the proportion of heart failure patients on beta-blockers is satisfactory, the number of patients with an optimal heart rate remains insufficient. The aim of this article is to examine the deleterious effect of an elevated resting heart rate in heart failure with systolic dysfunction, in order to overcome the therapeutic inertia and to improve the outcome in this patient group.

Heart failure is a major public health problem in industrialized countries. Its prognosis remains poor. The new European recommendations for heart failure management allow validation of the latest advances in the field. This article focuses on the definition, classification and treatment of chronic heart failure. Indeed, there are new aspects to consider such as, a new classification, a new therapeutic class and new remote monitoring solutions. On the contrary, there is no change in initial drug therapy, integration of the patient in a multidisciplinary program and the importance of treatment of comorbidities.

Sometimes, the emergency department is confronted with cases of repetitive vomiting and abdominal pain without organic causes. These patients come back again and again for this problem. All diagnostic tests are systematically negative. A well conducted history taking reveals a chronic cannabis addiction and the disappearance of symptomatology by taking hot showers. This presentation is pathognomonic of the cannabinoid hyperemesis syndrome.

Objectives: The ALERT algorithm, a telephone cardiopulmonary resuscitation (CPR) protocol, has been shown to help bystanders initiate CPR. Mobile phone communications may play a role in emergency calls and improve dispatchers' understanding of the rescuer's situation. However, there is currently no validated protocol for videoconference-assisted CPR (v-CPR). We initiated this study to validate an original protocol of v-CPR and to evaluate the potential benefit in comparison with classical telephone-CPR (t-CPR)., Materials and Methods: We developed an algorithm for v-CPR, adapted from the ALERT t-CPR protocol. A total of 180 students were recruited from secondary school and assigned randomly either to t-CPR or to v-CPR. A manikin was used to evaluate CPR performance., Results: The mean chest compression rate was higher in the v-CPR group (v-CPR: 110±16 vs. t-CPR: 86±28; P<0.0001), whereas depth was comparable between both groups (v-CPR: 48±13 vs. t-CPR: 47±16 mm; P=0.64). Hand positioning was correct in 91.7% with v-CPR, but only 68% with t-CPR (P=0.001). There was almost no 'hands-off' period in the v-CPR group [v-CPR: 0 (0-0.4) vs. t-CPR: 7 (0-25.5) s; P<0.0001], but the median no-flow time was increased in the v-CPR group [v-CPR: 146 (128-173.5) vs. t-CPR: 122 (105-143.5) s, P<0.0001]. The overall score of CPR performance was improved in the v-CPR group (P<0.001)., Conclusion: The v-CPR protocol allows bystanders to reach compression rates and depths close to guidelines and to reduce 'hands-off' events during CPR.

On the basis of the case report of a pregnant woman with acute pleuritis, this article describes the diagnostic modalities of dyspnea during pregnancy. The utility and effectiveness of bedside ultrasound examination by the emergency physician («POCUS») are reviewed in view of recent literature data. The ultrasound in this case is considered to be the extension of physical examination aiming at providing answers with immediate clinical relevance.

Direct and indirect injuries of the pharynx and larynx. The neck is characterized by a relatively complex anatomy and a very compact content. It therefore forms an extremely vulnerable part of the human body. Although uncommon, aero-digestive tract injuries caused by trauma present a challenging situation for both the emergency doctor and the head and neck surgeon. Clinical presentations may vary from severe acute distress with immediate life-threatening airway obstruction to apparently more reassuring situations. However, the latter turn out to be frequently misleading, since patients may deteriorate suddenly as the result of unrecognized injuries. In such cases, delayed diagnosis is often associated with increased morbidity and mortality. Due to its role in phonation, breathing and alimentation, injuries to the aero-digestive tract also expose the patient to severe later impairment and a poorer quality of life. Comprehensive airway control remains the highest and often most challenging priority for the emergency physician. Careful clinical examination combined with endoscopy and computed tomography imaging form the key elements in diagnosis and early recognition of patients who may require surgical management.

Aims: Primary prehospital Helicopter Emergency Medical Service (HEMS) interventions may play a role in timely reperfusion therapy for patients with ST-segment elevation myocardial infarction (STEMI). We designed a prospective study involving patients with acute myocardial infarction aimed at the evaluation of the potential benefit of such primary HEMS interventions as compared with classical Emergency Medical Services ground transport., Methods and Results: This prospective study was conducted from 1 July 2007 to 15 June 2012. Successive patients with STEMI eligible for percutaneous coronary intervention were included. Simulated ground-based access times were computed using a digital cartographic program, allowing the estimation of healthcare system delay from call to admission to the catheterization laboratory.During the study period, 4485 patients benefited from HEMS activations. Of these patients, 342 (8%) suffering from STEMI were transferred for primary percutaneous coronary intervention. The median primary response time was 11 min (interquartile range: 8-14 min) using the helicopter and 32 min (25-44 min) using road transport. The median transport time was 12 min (9-15 min) using HEMS and 50 min (36-56 min) by road. The median system delay using HEMS was 52 min (45-60 min), whereas this time was 110 min (95-126 min) by road. Finally, the system delay median gain was 60 min (47-72 min)., Conclusion: Using HEMS in a rural region allows STEMI patients to benefit from appropriate rescue care with delays similar to those seen in urban settings.

Aim: To improve the communication during shift handover in an emergency department., Methods: We observed the handover process and analysed the discourse between physicians at shift change first, and then we created two cognitive tools and tested their clinical impact on the field. We used different measures to evaluate this impact on the health care process including the frequency and type of information content communicated between physicians, duration of the handoff, physician self-evaluation of the quality of the handoff and a posthandover study of patient handling., Results: Our results showed that the patient's medical history, significant test results, recommendations (treatment plan) and patient follow-up were communicated to a greater extent when the tools are used. We also found that physicians spent more time at the bedside and less time consulting medical records using these tools., Conclusion: The present study showed how in-depth observations and analyses of real work processes can be used to better support the quality of patient care.

Objectives: Ventilator-associated pneumonia diagnosis remains a debatable topic. New definitions of ventilator-associated conditions involving worsening oxygenation have been recently proposed to make surveillance of events possibly linked to ventilator-associated pneumonia as objective as possible. The objective of the study was to confirm the effect of subglottic secretion suctioning on ventilator-associated pneumonia prevalence and to assess its concomitant impact on ventilator-associated conditions and antibiotic use., Design: Randomized controlled clinical trial conducted in five ICUs of the same hospital., Patients: Three hundred fifty-two adult patients intubated with a tracheal tube allowing subglottic secretion suctioning were randomly assigned to undergo suctioning (n = 170, group 1) or not (n = 182, group 2)., Main Results: During ventilation, microbiologically confirmed ventilator-associated pneumonia occurred in 15 patients (8.8%) of group 1 and 32 patients (17.6%) of group 2 (p = 0.018). In terms of ventilatory days, ventilator-associated pneumonia rates were 9.6 of 1,000 ventilatory days and 19.8 of 1,000 ventilatory days, respectively (p = 0.0076). Ventilator-associated condition prevalence was 21.8% in group 1 and 22.5% in group 2 (p = 0.84). Among the 47 patients with ventilator-associated pneumonia, 25 (58.2%) experienced a ventilator-associated condition. Neither length of ICU stay nor mortality differed between groups; only ventilator-associated condition was associated with increased mortality. The total number of antibiotic days was 1,696 in group 1, representing 61.6% of the 2,754 ICU days, and 1,965 in group 2, representing 68.5% of the 2,868 ICU days (p < 0.0001)., Conclusions: Subglottic secretion suctioning resulted in a significant reduction of ventilator-associated pneumonia prevalence associated with a significant decrease in antibiotic use. By contrast, ventilator-associated condition occurrence did not differ between groups and appeared more related to other medical features than ventilator-associated pneumonia.
