Evolution of REperfusion Strategies and impact on mortality in Old and Very OLD STEMI patients. The RESOVOLD-e-MUST study.

BACKGROUND: The use of myocardial reperfusion-mainly via angioplasty-has increased in our region to over 95%. We wondered whether old and very old patients have benefited from this development. METHODS: Setting: Greater Paris Area (Ile-de-France). DATA: Regional registry, prospective, including since 2003, data from 39 mobile intensive care units performing prehospital treatment of patients with ST segment elevation myocardial infarction (STEMI) (<24 h). PARAMETERS: Demographic, decision to perform reperfusion and outcome (in-hospital mortality). PRIMARY ENDPOINT: Reperfusion decision rate by decade over age 70. SECONDARY ENDPOINT: Outcome. RESULTS: We analysed the prehospital management of 27,294 patients. There were 21,311 (78%) men and 5,919 (22%) women with a median age of 61 (52-73 years). Among these patients, 8,138 (30%) were > 70 years, 3,784 (14%) > 80 years and 672 (2%) > 90 years.The reperfusion decision rate was 94%. It decreased significantly with age: 93, 90 and 76% in patients in their seventh, eighth and ninth decade, respectively. The reperfusion decision rate increased significantly over time. It increased in all age groups, especially the higher ones. Mortality was 6%. It increased significantly with age: 8, 16 and 25% in patients in their seventh, eighth and ninth decade, respectively. It significantly decreased over time in all age groups. The odds ratio of the impact of reperfusion decision on mortality reached 0.42 (0.26-0.68) in patients over 90 years. CONCLUSION: the increase in the reperfusion decision rate was the greatest in the oldest patients. It reduced mortality even in patients over 90 years of age.

Evolution of the use of intraosseous vascular access in prehospital advanced cardiopulmonary resuscitation: The IOVA-CPR study.

INTRODUCTION: Obtaining vascular access is crucial in critically ill patients. The EZ-IO® device is easy to use and has a high insertion success rate. Therefore, the use of intraosseous vascular access (IOVA) has gradually increased. AIM: We aim to determine how IOVA was integrated into management of vascular access during out-of-hospital cardiac arrest (OHCA) resuscitation. METHODS: Analysing the data from the OHCA French registry for events occurring between 1 January 2013 and 15 March 2021, we studied: demography, circumstances of occurrence and management including vascular access, delays and evolution. The primary outcome was the rate of IOVA implantation. RESULTS: Among the 7156 OHCA included in the registry, we analysed the 3964 (55%) who received cardiopulmonary resuscitation. The vascular access was peripheral in 3122 (79%) cases, intraosseous in 775 (20%) cases and central in 12 (<1%) cases. The use of IOVA has increased linearly (R2 = 0.61) during the 33 successive trimesters studied representing 7% of all vascular access in 2013 and 33% in 2021 (p = 0.001). It was significantly more frequent in traumatic cardiac arrest: 12% versus 5%; p < 0.0001. The first epinephrine bolus occurred significantly later in the IOVA group, at 6 (4-10) versus 5 (3-8) min; p < 0.0001. Survival rate in the IOVA group was significantly lower, at 1% versus 7%; p < 0.0001. CONCLUSION: The insertion rate of IOVA significantly increased over the studied period, to reach 30% of all vascular access in the management OHCA patients. The place of the intraosseous route in the strategy of venous access during the management of prehospital cardiac arrest has yet to be determined.

Prehospital treatment with zalunfiban (RUC-4) in patients with ST- elevation myocardial infarction undergoing primary percutaneous coronary intervention: Rationale and design of the CELEBRATE trial.

BACKGROUND: Early and complete restoration of target vessel patency in ST-elevation myocardial infarction (STEMI) is associated with improved outcomes. Oral P2Y12 inhibitors have failed to demonstrate either improved patency or reduced mortality when administered in the prehospital setting. Thus, there is a need for antiplatelet agents that achieve prompt and potent platelet inhibition, and that restore patency in the prehospital setting. Zalunfiban, a novel subcutaneously administered glycoprotein IIb/IIIa inhibitor designed for prehospital administration, has shown to achieve rapid, high-grade platelet inhibition that exceeds that of P2Y12 inhibitors. Whether prehospital administration of zalunfiban can improve clinical outcome is unknown. HYPOTHESIS: The present study is designed to assess the hypothesis that a single, prehospital injection of zalunfiban given in the ambulance, in addition to standard-of-care in patients with STEMI with intent to undergo primary percutaneous coronary intervention (PCI) will improve clinical outcome compared to standard-of-care with placebo. STUDY DESIGN: The ongoing CELEBRATE trial (NCT04825743) is a phase 3, randomized, double-blinded, placebo-controlled, international trial. Patients with STEMI intended to undergo primary PCI will receive treatment with a single subcutaneous injection containing either zalunfiban dose 1 (0.110 mg/kg), zalunfiban dose 2 (0.130 mg/kg) or placebo, and the study drug will be administered in the ambulance before transportation to the hospital. A target of 2499 patients will be randomly assigned to one of the treatment groups in a 1:1:1 ratio, ie, to have approximately 833 evaluable patients per group. The primary efficacy outcome is a ranked 7-point scale on clinical outcomes. The primary safety outcome is severe or life-threatening bleeding according to the Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO) criteria. SUMMARY: The CELEBRATE trial will assess whether a single prehospital subcutaneous injection of zalunfiban in addition to standard-of-care in patients with STEMI with intent to undergo primary PCI will result in improved clinical outcome.

Digit preference and biased conclusions in cardiac arrest studies.

BACKGROUND: In cardiac arrest (CA), time is directly predictive of patients' prognosis. The increase in mortality resulting from delayed cardiopulmonary resuscitation has been quantified minute by minute. Times reported in CA management studies could reflect a timestamping bias referred to as "digit preference". This phenomenon leads to a preference for certain numerical values (such as 2, 5, or 10) over others (such as 13). Our objective was to investigate whether or not digit preference phenomenon could be observed in reported times of the day related to CA management, as noted in a national registry. METHODS: We analyzed data from the French National Electronic Registry of Cardiac Arrests. We analyzed twelve times-of-the-day corresponding to each of the main steps of CA management reported by the emergency physicians who managed the patients in prehospital settings. We postulated that if CA occurred at random times throughout the day, then we could expect to see events related to CA management occurring at a similar rate each minute of each hour of the day, at a fraction of 1/60. We compared the fraction of times reported as multiples of 15 (0, 15, 30, and 45 - on the hour, quarters, half hour) with the expected fraction of 4/60 (i.e. 4 × 1/60). MAIN RESULTS: A total of 47,211 times-of-the-day in relation to 6131 CA were analyzed. The most overrepresented numbers were: 0, with 3737 occurrences (8% vs 2% expected, p < 0.0001) and 30, with 2807 occurrences (6% vs 2% expected, p < 0.0001). Times-of-the-day as multiples of 15 were overrepresented (22% vs 7% expected, p < 0.0001). CONCLUSION: Prospectively collected times were considerably influenced by digit preference phenomenon. Studies that are not based on automatic time recordings and that have not evaluated and considered this bias should be interpretated with caution.

A national population-based study of patients, bystanders and contextual factors associated with resuscitation in witnessed cardiac arrest: insight from the french RéAC registry.

BACKGROUND: In out-of-hospital cardiac arrest (OHCA), bystander initiated cardiopulmonary resuscitation (CPR) increases the chance of return of spontaneous circulation and survival with a favourable neurological status. Socioeconomic disparities have been highlighted in OHCA field. In areas with the lowest average socioeconomic status, OHCA incidence increased, and bystander CPR decreased. Evaluations were performed on restricted geographical area, and European evaluation is lacking. We aimed to analyse, at a national level, the impact of area-level social deprivation on the initiation of CPR in case of a witnessed OHCA. METHODS: We included all witnessed OHCA cases with age over 18 years from July 2011 to July 2018 form the OHCA French national registry. We excluded OHCA occurred in front of rescue teams or in nursing home, and patients with incomplete address or partial geocoding. We collected data from context, bystander and patient. The area-level social deprivation was estimated by the French version of the European Deprivation Index (in quintile) associated with the place where OHCA occurred. We assessed the associations between Utstein variables and social deprivation level using a mixed-effect logit model with bystander-initiated CPR. RESULTS: We included 23,979 witnessed OHCA of which 12,299 (51%) had a bystander-initiated CPR. More than one third of the OHCA (8,326 (35%)) occurred in an area from the highest quintile of social deprivation. The higher the area-level deprivation, the less the proportion of bystander-initiated CPR (56% in Quintile 1 versus 48% in Quintile 5). The In the multivariable analysis, bystander less often began CPR in areas with the highest deprivation level, compared to those with the lowest deprivation level (OR=0.69, IC95%: 0.63-0.75). CONCLUSIONS: The level of social deprivation of the area where OHCA occurred was associated with bystander-initiated CPR. It decreased in the more deprived areas although these areas also concentrate more younger patients.

Prevention of hypothermia in trauma victims - the HYPOTRAUM 2 study.

INTRODUCTION: Hypothermia is common in trauma patients. It contributes to increasing mortality rate. Hypothermia is multifactorial, favoured by exposure to cold, severity of the patient's state and interventions such as infusion of fluids at room temperature. AIM: To demonstrate that specific management of hypothermia (or of the risk of hypothermia) increases the number of trauma patients arriving at the hospital with a temperature >35°C. DESIGN: This is a prospective, multicentre, open-label, pragmatic, cluster randomized clinical trial of an expected 1,200 trauma patients included by 12 out-of-hospital mobile intensive care units (MICU). Trauma patients are included in a prehospital setting if they present at least one of the following criteria known to be associated with an increased incidence of hypothermia: ambient temperature <18°C, Glasgow coma scale <15, systolic arterial blood pressure <100 mm Hg or body temperature <35°C. Patients are randomized, by cluster, to receive a conventional management or 'interventional' nursing management associating: continuous epitympanic temperature monitoring, early installation in the heated ambulance (temperature target >30°C controlled by infrared thermometer), protection by a survival blanket, and use of heated solutes (temperature objective >35°C controlled by infrared thermometer). The primary end point is the prevalence of hypothermia on arrival at the hospital. The hypothesis tested is a reduction from 20% to 13% in the prevalence of hypothermia. Secondary end points are to evaluate the interaction between the effectiveness of the measures taken and: (1) the severity of the patients assessed by the Revised Trauma Score; (2) the meteorological conditions when they are managed; (3) the time of care; and (4) therapeutic interventions. DISCUSSION: This trial will assess the effectiveness of an invasive, out-of-hospital, temperature management on the onset of hypothermia in moderate to severe trauma patients. IMPACT: Specific management of hypothermia is expected to decrease hypothermia in trauma patients.

[Prevalence of advance directives and impact on the progress of cardiac arrest resuscitation in EHPAD]. / Prévalence des directives anticipées et impact sur le déroulement de la réanimation d'arrêts cardiaques en Ehpad.

Anticipated directives are of great value among patients living in residential care facilities for the elderly. Their prevalence in cases of cardiac arrest was studied. It was found that this issue is not systematically addressed. This results in the inappropriate use of resuscitation manoeuvres that could be avoided. This is an area that needs to be addressed in depth.

[Doctor-patient relationship: teenagers prefer "tu" to "vous"]. / Les adolescents préfèrent être tutoyés par leur médecin.

The quality of the relationship is important for the medical care of adolescents. The choice of the pronoun of address, "tu" or "vous", could be a determining factor in this relationship. A study of 220 adolescents showed that they preferred to be addressed as "tu". They waited for the doctor to offer it to them.

Pre-hospital administration of ticagrelor in diabetic patients with ST-elevation myocardial infarction undergoing primary angioplasty: A sub-analysis of the ATLANTIC trial.

OBJECTIVE: We investigated, in the contemporary era of ST-elevation myocardial infarction (STEMI) treatment, the influence of diabetes mellitus (DM) on cardiovascular outcomes, and whether pre-hospital administration of ticagrelor may affect these outcomes in a subgroup of STEMI patients with DM. BACKGROUND: DM patients have high platelet reactivity and a prothrombotic condition which highlight the importance of an effective antithrombotic regimen in this high-risk population. METHODS: In toal 1,630 STEMI patients enrolled in the ATLANTIC trial who underwent primary percutaneous coronary intervention (PCI) were included. Multivariate analysis was used to explore the association of DM with outcomes and potential treatment-by-diabetes interaction was tested. RESULTS: A total of 214/1,630 (13.1%) patients had DM. DM was an independent predictor of poor myocardial reperfusion as reflected by less frequent ST-segment elevation resolution (≥70%) after PCI (OR 0.59, 95% CI 0.43-0.82, P < 0.01) and was an independent predictor of the composite 30-day outcomes of death/new myocardial infarction (MI)/urgent revascularization/definite stent thrombosis (ST) (OR 2.80, 95% CI 1.62-4.85, P < 0.01), new MI or definite acute ST (OR 2.46, 95% CI 1.08-5.61, P = 0.03), and definite ST (OR 10.00, 95% CI 3.54-28.22, P < 0.01). No significant interaction between pre-hospital ticagrelor vs in-hospital ticagrelor administration and DM was present for the clinical, electrocardiographic and angiographic outcomes as well as for thrombolysis in myocardial infarction major bleeding. CONCLUSIONS: DM remains independently associated with poor myocardial reperfusion and worse 30-day clinical outcomes. No significant interaction was found between pre-hospital vs in-hospital ticagrelor administration and DM status. Further approaches for the treatment of DM patients are needed. CLINICAL TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT01347580.

Prognosis of cirrhotic patients admitted to Emergency Departments: A multicenter study.

OBJECTIVES: Life threatening complications can occur at any stage of cirrhosis progression. There are few studies on the prognosis of cirrhotic patients managed in an Emergency Department (ED) although management of patients will occur in the ED. The objective of our study was to determine the risk factors for mortality in cirrhotic patients who visited to the ED. METHODS: All cirrhotic patients attending ED in three different university hospitals of Assistance Publique - Hôpitaux de Paris between January 2014 and June 2015 were identified by a retrospective analysis of digital records and included in the study. The primary end-point was 30-day mortality in all cirrhotic patients who visited the ED. RESULTS: A total of 609 ED visits were analyzed among 224 patients: 115 (51%) presented a cirrhosis of alcoholic origin, 43 (19%) were caused by Hepatitis C, 28 (13%) of mixed origin (viral and alcoholic), 17 (8%) were caused by Hepatitis B and 21 (9%) of other origins. Fifty-five (25%) of these patients died within 30 days of their initial presentation to the ED. In multivariate analysis, the age (Odds Ratio: 1.04 [1.01-1.07]), cirrhosis associated with hepatocellular carcinoma (OR: 3.07 [1.37-6.91]), serum creatinine at admission (OR: 1.01 [1.01-1.02]), serum bilirubin at admission (OR: 1.01 [1.01-1.02]) and health impairment (OR: 2.57 [1.28-5.16]) were associated with mortality. CONCLUSIONS: The mortality rate of cirrhotic patients attending an ED was high. The prognosis of cirrhotic patients admitted to the ED depended on the severity of the liver and other organ dysfunction. The presence of a hepatocellular carcinoma on admission was also a risk factor for death.

Role of Student Nurse in the Prehospital Medical Teams Responding to the Scene of A Terrorist Attack in France.

BACKGROUND: The terrorist attacks in Paris and in Saint-Denis in November 2015 were unprecedented events involving various human and material resources. These events question the role of nurse students in prehospital teams. PURPOSE: To investigate nursing students' preference about whether they wished to participate in the prehospital care during a terrorist attack. METHODS: This cross-sectional study was conducted with student nurses, from two nursing schools in the Greater Paris area. They completed an anonymous survey assessing the desire to be called to help the mobile intensive care units (MICU) or another ward; whether their presence should be mandatory, and the feelings associated with their experience. The responses were collected with a visual analogue scale and could range from 1 (yes, very much) to 10 (no, not at all). A Chi-square test was performed for qualitative variables and a Mann-Whitney test for quantitative variables. FINDINGS: Among 225 students, 205 (91%) responded, 133 (65%) were women. When on duty, 169 (82%) would have preferred to accompany the MICU team, compared with 31 (15%) who would have preferred not to go. Overall, 146 students (71%) considered that this presence should be optional. Only gender was significantly associated with the choice to accompany the MICU team (W = 87% vs. M = 13%; p = .002). Students expressed a moderate feeling of frustration and fear. DISCUSSION: Students would prefer to assist the MICU team responding to the scene of a terrorist attack but feel this choice should be optional. A discussion in nursing schools and universities should be considered for the implementation of a "systematic" procedure to ensure the student's willingness to participate in such interventions.

[Impact of extreme temperatures on primary care requirement in France: the CHAUFOS Study (2010-2018).] / Impact des températures extrêmes sur la demande de soins primaires en France : l'étude CHAFO (2010-2018).

INTRODUCTION: The health impact of cold and hot waves is major. Nevertheless, the respective impact of extreme high and low temperatures remains controversial. METHOD: The daily number of (1) patients managed by SAMU 93 dispatching centre – primary care requirement indicator, (2) Mobile Intensive Care Unit (MICU) interventions – patient severity indicator and (3) number of deaths have been recorded. Daily minimum and maximum temperatures were recorded from 2010 to 2018. The analysis covered the 10 warmest and coldest days of each year (2 × 70 days), and the 30 warmest and coldest days of the total period (2 × 30 days). RESULTS: Over 2,702 days, 1,513,070 patients, 89,478 MICU interventions and 7,350 deaths were analysed. Median temperature: 16.0[10.4-21.6]°C.The coldest days were associated with a significant increase in patients managed (665[609-764] vs 538[474-619]; P < 0.001), MICU interventions (35[32-39] vs 33 [28-38]; P = 0.006) and deaths (3[2-5] vs 2[1-4]; P = 0.0008) considering the 10 days of extreme temperatures in each year and a significant increase in patients managed 615[580-698] vs 542[475-627]; P < 0.001) considering the 30-day extreme of the period.The hottest days were associated with a significant decrease in patients managed (484[443-549] vs 538[474-619]; P < 0.001), MICU interventions (31[25-37] vs 33[28-38]; P = 0.006) and deaths (2[1-3] vs 2[1-4]; P = 0.0008) considering the 10 extreme days of each year and a significant decrease in patients managed (536[479-576] vs 542[475-627]; P < 0.001) considering the 30 extreme days of the period. CONCLUSION: Primary care requirement, number of severe patients and mortality increased significantly with extreme low of temperature.

Optimal timing of an invasive strategy in patients with non-ST-elevation acute coronary syndrome: a meta-analysis of randomised trials.

BACKGROUND: A routine invasive strategy is recommended for patients with non-ST-elevation acute coronary syndromes (NSTE-ACS). However, optimal timing of invasive strategy is less clearly defined. Individual clinical trials were underpowered to detect a mortality benefit; we therefore did a meta-analysis to assess the effect of timing on mortality. METHODS: We identified randomised controlled trials comparing an early versus a delayed invasive strategy in patients presenting with NSTE-ACS by searching MEDLINE, Cochrane Central Register of Controlled Trials, and Embase. We included trials that reported all-cause mortality at least 30 days after in-hospital randomisation and for which the trial investigators agreed to collaborate (ie, providing individual patient data or standardised tabulated data). We pooled hazard ratios (HRs) using random-effects models. This meta-analysis is registered at PROSPERO (CRD42015018988). FINDINGS: We included eight trials (n=5324 patients) with a median follow-up of 180 days (IQR 180-360). Overall, there was no significant mortality reduction in the early invasive group compared with the delayed invasive group HR 0·81, 95% CI 0·64-1·03; p=0·0879). In pre-specified analyses of high-risk patients, we found lower mortality with an early invasive strategy in patients with elevated cardiac biomarkers at baseline (HR 0·761, 95% CI 0·581-0·996), diabetes (0·67, 0·45-0·99), a GRACE risk score more than 140 (0·70, 0·52-0·95), and aged 75 years older (0·65, 0·46-0·93), although tests for interaction were inconclusive. INTERPRETATION: An early invasive strategy does not reduce mortality compared with a delayed invasive strategy in all patients with NSTE-ACS. However, an early invasive strategy might reduce mortality in high-risk patients. FUNDING: None.

Thrombus aspiration and prehospital ticagrelor administration in ST-elevation myocardial infarction: Findings from the ATLANTIC trial.

BACKGROUND: The potential interactions between prehospital (pre-H) ticagrelor administration and thrombus aspiration (TA) in patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) have never been studied. Therefore, we evaluated the potential benefit of TA and pre-H ticagrelor treatment in patients enrolled in the ATLANTIC trial (NCT01347580). METHODS: This analysis included 1,630 patients who underwent primary PCI. Multivariate analysis was used to explore the potential association of TA and pre-H treatment to clinical outcomes. Potential interactions between TA and pre-H ticagrelor were also explored. RESULTS: A total of 941 (57.7%) patients underwent TA. In adjusted multivariate logistic model, pre-H ticagrelor treatment was significantly associated with less frequent new MI or definite stent *thrombosis (ST) (odds ratio [OR] 0.43, 95% CI 0.20-0.92, P=.031), or definite ST (OR 0.26, 95% CI 0.07-0.91, P=.036) at 30 days. Patients treated with TA had higher frequency of Thrombolysis in Myocardial Infarction (TIMI) flow 0-1 compared with no-TA group (80.7% vs 51.9%, P<.0001). TA when also adjusted for TIMI flow 0-1 showed significant association only for higher bailout use of glycoprotein IIb/IIIa inhibitors (OR 1.72, 95% CI 1.18-2.50, P=.004) and more frequent 30-day TIMI major bleeding (OR 2.92, 95% CI 1.10-7.76, P=.032). No significant interactions between TA and pre-H ticagrelor were present for the explored end points. CONCLUSIONS: TA when left to physicians' discretion was used in high-risk patients, was associated with bailout use of glycoprotein IIb/IIIa inhibitors and TIMI major bleeding, and had no impact on 30-day clinical outcomes. Conversely, pre-H ticagrelor treatment predicted lower 30-day rates of ST or new MI without interaction with TA.

Duration of ischemia and treatment effects of pre- versus in-hospital ticagrelor in patients with ST-segment elevation myocardial infarction: Insights from the ATLANTIC study.

BACKGROUND: Among patients with STEMI in the ATLANTIC study, pre-hospital administration of ticagrelor improved post-PCI ST-segment resolution and 30-day stent thrombosis. We investigated whether this clinical benefit with pre-hospital ticagrelor differs by ischemic duration. METHODS: In a post hoc analysis we compared absence of ST-segment resolution post-PCI and stent thrombosis at 30 days between randomized treatment groups (pre- versus in-hospital ticagrelor) stratified by symptom onset to first medical contact (FMC) duration [≤1 hour (n = 773), >1 to ≤3 hours (n = 772), and >3 hours (n = 311)], examining the interaction between randomized treatment strategy and duration of symptom onset to FMC for each outcome. RESULTS: Patients presenting later after symptom onset were older, more likely to be female, and have higher baseline risk. Patients with symptom onset to FMC >3 hours had the greatest improvement in post-PCI ST-segment elevation resolution with pre- versus in-hospital ticagrelor (absolute risk difference: ≤1 hour, 2.9% vs. >1 to ≤3 hours, 3.6% vs. >3 hours, 12.2%; adjusted p for interaction = 0.13), while patients with shorter duration of ischemia had greater improvement in stent thrombosis at 30 days with pre- versus in-hospital ticagrelor (absolute risk difference: ≤1 hour, 1.3% vs. >1 hour to ≤3 hours, 0.7% vs. >3 hours, 0.4%; adjusted p for interaction = 0.55). Symptom onset to active ticagrelor administration was independently associated with stent thrombosis at 30 days (adjusted OR 1.89 per 100 minute delay, 95%CI 1.20-2.97, P < .01), but not post-PCI ST-segment resolution (P = .41). CONCLUSIONS: The effect of pre-hospital ticagrelor to reduce stent thrombosis was most evident when given early within 3 hours after symptom onset, with delay in ticagrelor administration after symptom onset associated with higher rate of stent thrombosis. These findings re-emphasize the need for early ticagrelor administration in primary PCI treated STEMI patients.

Early psychological impact of Paris terrorist attacks on healthcare emergency staff: A cross-sectional study.

BACKGROUND: The terrorist attacks in Paris and Saint Denis on November 13, 2015 were an unprecedented traumatic event in France. It was an especially distressing ordeal for the healthcare personnel involved in the care of the victims. The aim of this study was to estimate the effect of direct participation in the rescue on posttraumatic stress disorder (PTSD) symptoms among these workers. METHODS: Less than a month later, 613 healthcare providers (professionals and paraprofessionals) from three hospitals in the Paris suburbs were asked to complete an anonymous questionnaire. A multivariable Poisson model estimated the effect of participating onsite in the rescue (exposure variable) on the number of PTSD symptoms measured by the Trauma Screening Questionnaire (TSQ; outcome variable), adjusted for covariates. RESULTS: Two hundred thirty-three providers completed the assessment (38% response rate), 130 participated directly in the rescue (56%). Participation was associated with a higher number of symptoms of PTSD (RR = 1.34, P = .002) than for nonparticipants. Female gender (RR = 1.39, P < .001) and basic (vs. advanced or intermediate) life-saving training (RR = 1.42, P = .004) were also associated with more PTSD symptoms. Participants in the rescue were at 2.76 times more risk of a probable PTSD diagnosis (OR = 2.76, P = .037), defined as reporting at least six PTSD symptoms. Sensitivity analyses using propensity score matching supported the robustness of our findings. CONCLUSIONS: Healthcare providers directly involved in the rescue of the victims of the Paris and Saint Denis attacks reported a significantly higher psychological impact, defined by PTSD symptoms, than those not directly involved.

Specialist Advice Support for Management of Severe Hereditary Angioedema Attacks: A Multicenter Cluster-Randomized Controlled Trial.

STUDY OBJECTIVE: Hereditary angioedema is a rare disease associated with unpredictable, recurrent attacks of potentially life-threatening edema. Management of severe attacks is currently suboptimal because emergency medical teams are often unaware of new specific treatments. The objective of this trial is to test whether a dedicated national telephone care-management strategy would reduce resource use during severe hereditary angioedema attacks. METHODS: We conducted a cluster-randomized multicenter prospective trial of patients with a documented diagnosis of hereditary angioedema (type I, II or FXII hereditary angioedema). Participants were enrolled between March 2013 and June 2014 at 8 participating reference centers. The randomized units were the reference centers (clusters). Patients in the intervention arm were given a national free telephone number to call in the event of a severe attack. Emergency physicians in the SOS-hereditary angiœdema (SOS-HAE) call center were trained to advise or prescribe specific treatments. The primary outcome was number of admissions for angioedema attacks. Economic evaluation was also performed. RESULTS: We included 100 patients in the SOS-HAE group and 100 in the control group. During the 2 years, there were 2,368 hereditary angioedema attacks among 169 patients (85%). Mean number of hospital admissions per patient in the 2-year period was significantly greater in the usual-practice group (mean 0.16 [range 0 to 2] versus 0.03 [range 0 to 1]); patient risk difference was significant: -0.13 (95% confidence interval -0.22 to -0.04; P=.02). Probabilistic sensitivity graphic analysis indicated a trend toward increased quality-adjusted life-years in the SOS-HAE group. CONCLUSION: A national dedicated call center for management of severe hereditary angioedema attacks is associated with a decrease in hospital admissions and may be cost-effective if facilities and staff are available to deliver the intervention alongside existing services.

Procedural Sedation and Analgesia in Trauma Patients in an Out-of-Hospital Emergency Setting: A Prospective Multicenter Observational Study.

BACKGROUND: The quality of procedural analgesia and sedation among trauma patients has not been studied much in the prehospital setting. The main objective of this study was to characterize the quality of procedural analgesia sedation practices in prehospital settings in trauma patients. METHODS: This was an open-label observational prospective multicenter study (January 01, 2012-December 31, 2013). We included all consecutive trauma victims undergoing a potentially painful procedure on the accident scene. The primary endpoint was the procedural pain intensity. RESULTS: Data for 210 patients aged 11 to 98 years were analyzed. The most common lesions were limb fractures or dislocations. The most common procedures were limb realignment and splinting. Overall, 25 different drug combinations [with paracetamol [acetaminophen], non-steroidal anti-inflammatory drugs, nefopam, opioids, loco-regional anesthesia, Equimolar Mixture of Oxygen/Nitrous Oxide (EMONO), sedative drugs] were used by the emergency medical services (EMS). One hundred seventeen patients (55%) received either one or two sedative drugs (among ketamine, propofol, and midazolam), 171 patients (81%) received morphine that was combined with a sedative drug in 54% of cases. During the procedure, 95 patients, 45% [95% Confidence Interval (CI) 39-52] experienced intense to severe pain. Among patients who received sedative drugs, 27% (32/117) had intense to severe pain vs. 68% (63/93) in patients who did not, that is, 40% difference [95% CI 33.8-47.0]. Seventeen patients (8%) experienced 18 adverse events of which 6 were respiratory adverse events. A deep sedation occurred in 17 patients. No center had any specific protocols for procedural sedation analgesia. CONCLUSION: Procedural sedation-analgesia was inadequate in almost half of the trauma patients in the out-of-hospital setting. The reasons of these failures were probably multiple. The non-administration of a sedative drug despite an indication or non-adapted doses, in the context of a lack of specific protocols, was certainly one of them.

Effect of Bag-Mask Ventilation vs Endotracheal Intubation During Cardiopulmonary Resuscitation on Neurological Outcome After Out-of-Hospital Cardiorespiratory Arrest: A Randomized Clinical Trial.

Importance: Bag-mask ventilation (BMV) is a less complex technique than endotracheal intubation (ETI) for airway management during the advanced cardiac life support phase of cardiopulmonary resuscitation of patients with out-of-hospital cardiorespiratory arrest. It has been reported as superior in terms of survival. Objectives: To assess noninferiority of BMV vs ETI for advanced airway management with regard to survival with favorable neurological function at day 28. Design, Settings, and Participants: Multicenter randomized clinical trial comparing BMV with ETI in 2043 patients with out-of-hospital cardiorespiratory arrest in France and Belgium. Enrollment occurred from March 9, 2015, to January 2, 2017, and follow-up ended January 26, 2017. Intervention: Participants were randomized to initial airway management with BMV (n = 1020) or ETI (n = 1023). Main Outcomes and Measures: The primary outcome was favorable neurological outcome at 28 days defined as cerebral performance category 1 or 2. A noninferiority margin of 1% was chosen. Secondary end points included rate of survival to hospital admission, rate of survival at day 28, rate of return of spontaneous circulation, and ETI and BMV difficulty or failure. Results: Among 2043 patients who were randomized (mean age, 64.7 years; 665 women [32%]), 2040 (99.8%) completed the trial. In the intention-to-treat population, favorable functional survival at day 28 was 44 of 1018 patients (4.3%) in the BMV group and 43 of 1022 patients (4.2%) in the ETI group (difference, 0.11% [1-sided 97.5% CI, -1.64% to infinity]; P for noninferiority = .11). Survival to hospital admission (294/1018 [28.9%] in the BMV group vs 333/1022 [32.6%] in the ETI group; difference, -3.7% [95% CI, -7.7% to 0.3%]) and global survival at day 28 (55/1018 [5.4%] in the BMV group vs 54/1022 [5.3%] in the ETI group; difference, 0.1% [95% CI, -1.8% to 2.1%]) were not significantly different. Complications included difficult airway management (186/1027 [18.1%] in the BMV group vs 134/996 [13.4%] in the ETI group; difference, 4.7% [95% CI, 1.5% to 7.9%]; P = .004), failure (69/1028 [6.7%] in the BMV group vs 21/996 [2.1%] in the ETI group; difference, 4.6% [95% CI, 2.8% to 6.4%]; P < .001), and regurgitation of gastric content (156/1027 [15.2%] in the BMV group vs 75/999 [7.5%] in the ETI group; difference, 7.7% [95% CI, 4.9% to 10.4%]; P < .001). Conclusions and Relevance: Among patients with out-of-hospital cardiorespiratory arrest, the use of BMV compared with ETI failed to demonstrate noninferiority or inferiority for survival with favorable 28-day neurological function, an inconclusive result. A determination of equivalence or superiority between these techniques requires further research. Trial Registration: clinicaltrials.gov Identifier: NCT02327026.
