RESUMO
BACKGROUND: Emergency Departments (ED) have seen an increasing number of older patients who are mostly referred following a call to the Emergency Medical Services (EMS). Long waiting times in settings, which are not designed to meet older patients' needs, may increase the risk of hospital-acquired complications. Unnecessary visits should therefore be avoided as much as possible. The objective of the study was to evaluate whether a program to provide geriatric knowledge and tools to the dispatching physicians of the EMS could decrease ED referrals of older patients. METHODS: Design: Before-and-after study with two 6-month periods before and after intervention. PARTICIPANTS: All calls received by a dispatching physician of the Rhône EMS from 8 am to 6 pm concerning patients aged 75 years or above during the study period. INTERVENTION: A program consisting of training dispatching physicians in the specific care of older patients and the developing, with a multidisciplinary team, of specific tools for dispatching physicians. OUTCOME: Proportion of ED referrals of patients aged 75 years or above after a call to the EMS. RESULTS: A total of 2671 calls to the Rhône EMS were included corresponding to 1307 and 1364 patients in the pre-and post-intervention phases, respectively. There was no significant difference in the proportion of referrals to the ED between the pre-intervention (61.7%) and the post-intervention (62.8%) phases (p = 0.57). Contact of the patients with their General Practitioner (GP) in the month preceding the call was associated with a 22% reduced probability of being referred to an ED. CONCLUSIONS: No beneficial effect of the intervention was demonstrated. This strategy of intervention is probably not effective enough in such time-constraint environment. Other strategies with a specific parallel dispatching of geriatric calls by geriatricians should be tested to avoid these unnecessary ED referrals. TRIAL REGISTRATION: ClinicalTrials NCT02712450.

BACKGROUND: Adrenaline is recommended during cardio-pulmonary resuscitation. The optimal dose remains debated, and the effect of lower than recommended dose is unknown. OBJECTIVE: To compare the outcome of patients treated with the recommended, lower or higher cumulative doses of adrenaline. DESIGN, SETTINGS, PARTICIPANTS: Patients were included from the French National Cardiac Arrest Registry and were grouped based on the received dose of adrenaline: recommended, higher and lower dose. OUTCOME MEASURES AND ANALYSIS: The primary endpoint was good neurologic outcome at 30 days post-OHCA, defined by a cerebral performance category (CPC) of less than 3. Secondary endpoints included return of spontaneous circulation and survival to hospital discharge. A multiple propensity score adjustment approach was performed. MAIN RESULTS: 27 309 patients included from July 1st 2011 to January 1st 2019 were analysed, mean age was 68 (57-78) years and 11.2% had ventricular fibrillation. 588 (2.2%) patients survived with a good CPC score. After adjustment, patients in the high dose group had a significant lower rate of good neurologic outcome (OR, 0.6; 95% CI, 0.5-0.7). There was no significant difference for the primary endpoint in the lower dose group (OR, 0.8; 95% CI, 0.7-1.1). There was a lower rate of survival to hospital discharge in the high-dose group vs. standard group (OR, 0.5; 95% CI, 0.5-0.6). CONCLUSION: The use of lower doses of adrenaline was not associated with a significant difference on survival good neurologic outcomes at D30. But a higher dose of adrenaline was associated with a lower rate of survival with good neurological outcomes and poorer survival at D30.

BACKGROUND: Traumatic cardiac arrests (TCAs) are associated with high mortality and the majority of deaths occur at the prehospital scene. The aim of the present study was to assess, in a prehospital physician-led emergency medical system, the factors associated with sustained return of spontaneous circulation (ROSC) in TCA, including advanced life procedures. The secondary objectives were to assess factors associated with 30-day survival in TCA, evaluate neurological recovery in survivors, and describe the frequency of organ donation among patients experiencing a TCA. METHODS: We conducted a retrospective study of all TCA patients included in the French nationwide cardiac arrest registry from July 2011 to November 2020. Multivariable logistic regression analysis was used to identify factors independently associated with ROSC. RESULTS: A total of 120,045 out-of-hospital cardiac arrests were included in the registry, among which 4,922 TCA were eligible for analysis. Return of spontaneous circulation was sustained on-scene in 21.1% (n = 1,037) patients. Factors significantly associated with sustained ROSC were not-asystolic initial rhythms (pulseless electric activity (odds ratio [OR], 1.81; 95% confidence interval [CI], 1.40-2.35; p < 0.001), shockable rhythm (OR, 1.83; 95% CI, 1.12-2.98; p = 0.016), spontaneous activity (OR, 3.66; 95% CI, 2.70-4.96; p < 0.001), and gasping at the mobile medical team (MMT) arrival (OR, 1.40; 95% CI, 1.02-1.94; p = 0.042). The MMT interventions significantly associated with ROSC were as follows: intravenous fluid resuscitation (OR, 3.19; 95% CI, 2.69-3.78; p < 0.001), packed red cells transfusion (OR, 2.54; 95% CI, 1.84-3.51; p < 0.001), and external hemorrhage control (OR, 1.74; 95% CI, 1.31-2.30; p < 0.001). Among patients who survived (n = 67), neurological outcome at Day 30 was favorable (cerebral performance categories 1-2) in 72.2% cases (n = 39/54) and 1.4% (n = 67/4,855) of deceased patients donated one or more organ. CONCLUSION: Sustained ROSC was frequently achieved in patients not in asystole at MMT arrival, and higher ROSC rates were achieved in patients benefiting from specific advanced life support interventions. Organ donation was somewhat possible in TCA patients undergoing on-scene resuscitation. LEVEL OF EVIDENCE: Prognostic and epidemiologic, Level III.

BACKGROUND: Among patients successfully resuscitated after an out-of-hospital cardiac arrest (OHCA), 10% to 15% evolve toward brain death (BD), thus becoming potential organ donors. RESEARCH QUESTION: Is it possible to establish a score for early estimation of BD risk after OHCA? STUDY DESIGN AND METHODS: The BD after cardiac arrest (BDCA) score was developed from data available within 24 hours after OHCA from two OHCA trials: Cyclosporine in Cardiac Arrest Resuscitation and Erythropoietin After OHCA. The BDCA score was then validated in another large prospective multicenter data set. The main outcome was the occurrence of BD. Independent prognostic covariates for BD were identified using a binomial two-stage adaptive least absolute shrinkage and selection operator procedure. RESULTS: The development cohort included 569 patients alive 24 hours after OHCA, among whom 84 (14.8%) experienced BD. Independent predictors of BD used to build the BDCA score were being female (4 points), nonshockable rhythm (24 points), cardiac cause of OHCA (-6 points), neurological cause of OHCA (45 points), natremia at 24 hours (natremia in millimoles per liter minus 140 points), and vasoactive drug at admission (4 points) and at 24 hours (6 points). The area under the curve (AUC) of the BDCA score was 0.82 (95% CI, 0.77-0.86), and the discrimination value in the validation cohort (n = 487) was consistent (AUC, 0.81; 95% CI, 0.76-0.86). In the validation cohort, BD occurred in 4.0%, 20.4%, and 67.7% of patients with scores of < 20, 20 to 50, and > 50, respectively. INTERPRETATION: The BDCA score allows early detection of patients with a high probability of experiencing BD, which may help increase organ donation after OHCA.

OBJECTIVE: The aim of the study was to compare outcomes after out-of-hospital cardiac arrest (OHCA) between comparable female and male OHCA cohorts in a large nationwide registry. METHODS: This was a national multicentre retrospective, case-control propensity score-matched study based on French National Cardiac Arrest Registry data from 1 July 2011 to 21 September 2017. Female and male survival rates at D30 were compared. RESULTS: At baseline 66 395 OHCA victims were included, of which 34.3% were women. At hospital admission, survival was 18.2% for female patients and 20.2% for male patients [odds ratio (OR), 1.138 (1.092-1.185)]; at 30 days, survival was 4.3 and 5.9%, respectively [OR, 1.290 (1.191-1.500)]. After matching (14 051 patients within each group), female patients received less advanced life support by mobile medical team (MMT), they also had a longer no-flow duration and shorter resuscitation effort by MMT than male patients. However, 15.3% of female patients vs. 9.1% of male patients were alive at hospital admission [OR, 0.557 (0.517-0.599)] and 3.2 vs. 2.6% at D30 [OR, 0.801 (0.697-0.921)], with no statistically significant difference in neurological outcome [OR, 0.966 (0.664-1.407)]. CONCLUSIONS: In this large nationwide matched OHCA study, female patients had a better chance of survival with no significant difference in neurological outcome. We also noticed that female patients received delayed care with a shorter resuscitation effort compared to men; these complex issues warrant further specific investigation. Encouraging bystanders to act as quickly as possible and medical teams to care for female patients in the same way as male patients should increase survival rates.

BACKGROUND: Epinephrine effectiveness and safety are still questioned. It is well known that the effect of epinephrine varies depending on patients' rhythm and time to injection. OBJECTIVE: We aimed to assess the association between epinephrine use during out-of-hospital cardiac arrest (OHCA) care and patient 30-day (D30) survival. METHODS: Between 2011 and 2017, 27,008 OHCA patients were included from the French OHCA registry. We adjusted populations using a time-dependent propensity score matching. Analyses were stratified according to patient's first rhythm. After matching, 2837 pairs of patients with a shockable rhythm were created and 20,950 with a nonshockable rhythm. RESULTS: Whatever the patient's rhythm (shockable or nonshockable), epinephrine use was associated with less D30 survival (odds ratio [OR] 0.508; 95% confidence interval [CI] 0.440-0.586] and OR 0.645; 95% CI 0.549-0.759, respectively). In shockable rhythms, on all outcomes, epinephrine use was deleterious. In nonshockable rhythms, no difference was observed regarding return of spontaneous circulation and survival at hospital admission. However, epinephrine use was associated with worse neurological prognosis (OR 0.646; 95% CI 0.549-0.759). CONCLUSIONS: In shockable and nonshockable rhythms, epinephrine does not seem to have any benefit on D30 survival. These results underscore the need to perform further studies to define the optimal conditions for using epinephrine in patients with OHCA.

BACKGROUND: With a survival rate of 6 to 11%, out-of-hospital cardiac arrest (OHCA) remains a healthcare challenge with room for improvement in morbidity and mortality. The guidelines emphasize the highest possible quality of cardiopulmonary resuscitation (CPR) and chest compressions (CC). It is essential to minimize CC interruptions, and therefore increase the chest compression fraction (CCF), as this is an independent factor for survival. Survival is significantly and positively correlated with the suitability of CCF targets, CC frequency, CC depth, and brief predefibrillation pause. CC guidance improves adherence to recommendations and allows closer alignment with the CC objectives. The possibility of improving CCF by lengthening the time between two CC relays and the effect of real-time feedback on the quality of the CC must be investigated. METHODS: Using a 2 × 2 factorial design in a multicenter randomized trial, two hypotheses will be tested simultaneously: (i) a 4-min relay rhythm improves the CCF (reducing the no-flow time) compared to the currently recommended 2-min relay rate, and (ii) a guiding tool improves the quality of CC. Primary outcomes (i) CCF and (ii) correct compression score will be recorded by a real-time feedback device. Five hundred adult nontraumatic OHCAs will be included over 2 years. Patients will be randomized in a 1:1:1:1 distribution receiving advanced CPR as follows: 2-min blind, 2 min with guidance, 4-min blind, or 4 min with guidance. Secondary outcomes are the depth, frequency, and release of CC; length (care, no-flow, and low-flow); rate of return of spontaneous circulation; characteristics of advanced CPR; survival at hospital admission; survival and neurological state on days 1 and 30 (or intensive care discharge); and dosage of neuron-specific enolase on days 1 and 3. DISCUSSION: This study will contribute to assessing the impact of real-time feedback on CC quality in practical conditions of OHCA resuscitation. It will also provide insight into the feasibility of extending the relay rhythm between two rescuers from the currently recommended 2 to 4 min. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03817892 .

BACKGROUND: In patients with suspected stroke, brain imaging is recommended in the acute phase for appropriate management and treatment. Both computed tomography (CT) and magnetic resonance imaging (MRI) are considered reasonable choices for initial brain imaging. When both techniques are available, choosing one or the other might be associated with specific factors related either to patients, stroke symptoms, and severity or management organization. METHODS: The study was performed within the STROKE 69 database, a population-based cohort of all adult patients with suspected stroke admitted in one of the emergency departments (ED), primary stroke center, or stroke center of the Rhône County, from November 2015 to December 2016. Patients were included if they were admitted within 24 h following either symptom onset or last known normal. To identify factors potentially associated with the choice of initial brain imaging, a multivariate logistic regression was performed. RESULTS: Among the 3,244 patients with suspected stroke enrolled in the STROKE69 cohort, 3,107 (95.8%) underwent brain imaging within the first 24 h after admission. Among those 74.6% underwent CT as initial imaging while 25.4% had an MRI. In multivariate analyses, several factors were associated with a lower probability of having an MRI as initial brain imaging versus CT. These were either patient characteristics: older age (>80 years old, OR 0.39 [95% CI 0.28-0.54]), preexisting disability (OR 0.55 [95% CI 0.36-0.84]), use of anticoagulants (OR 0.52 [95% CI 0.33-0.81]), stroke characteristics: stroke of unknown onset (OR 0.42 [95% CI 0.31-0.58]) or factors associated with overall management: onset-to-door time (>6 h, OR 0.38 [95% CI 0.23-0.60]), initial admission to ED (OR 0.02 [95% CI 0.02-0.04]) or intensive care unit (OR 0.01 [95% CI 0.001-0.08]), personal transport (OR 0.66 [95% CI 0.45-0.96]), and admission during working hours (OR 0.65 [95% CI 0.51-0.84]). CONCLUSIONS: Besides CT or MRI availability, a number of other parameters could influence the choice of first imaging in case of stroke suspicion. These are related to patient characteristics, type of stroke symptoms, and type of organization.

AIM: Cardiac arrest (CA) was considered irreversible until 1960, when basic cardiopulmonary resuscitation (CPR) was defined. CPR guidelines include early recognition of CA, rapid and effective CPR, effective defibrillation strategies and organized post-resuscitation to ensure a strengthening of the survival chain. Bystanders are the key to extremely early management, which is associated with the early medical care provided by EMS. This study aims to assess the prognosis of a bystander's cardiac CPR when it is initiated by the Dispatch Centre (DC). METHODS: We included patients in 3 groups according to who initiated the CPR. The groups were matched according to multiple propensity partition methods. We presented our results in terms of 30-day survival and neurological prognosis. RESULTS: 85,634 patients were included. Statistical study focused on 18,185 patients once the exclusion criteria were applied. 12,743 (70.1%) are men and the average age is 70.1 years. Survival at D30 was 5.11% in the absence of CPR, 8.86% with bystander initiation and 7.35% with DC initiation (pâ¯<â¯0.001). Survival at D30 with favourable neurologic prognosis (CPC 1-2) was 76.30%, 83.69% and 82.82%, respectively. Our results show a 3.75% increase in the chance of survival at D30 if CPR was initiated by bystanders compared to patients for whom CPR was not initiated, a 2.25% increase in survival in the group that received from CPR initiated by the DC compared to the group that did not receive CPR. CONCLUSIONS: Bystander CPR initiated by the DC represents a suitable option following out-of-hospital cardiac arrest.

BACKGROUND: The incidence of cardiac arrest (CA) in nursing homes is rising. Our objective was to compare nursing home CAs with at-home CAs in patients aged 65 and over with regard to the CAs' characteristics, the use and characteristics of cardiopulmonary resuscitation (CPR), and the outcome. METHODS: We performed an ancillary analysis of a French nationwide cohort of over-65 patients having experienced an out-of-hospital CA (at home or in a nursing home) treated by a physician-manned mobile intensive care unit (MICU) between July 2011 and September 2015. RESULTS: Out of 21,720 CAs, 1907 (9%) occurred in a nursing home. The presence of a witness was more frequent in the nursing home than at home (77% vs. 62%, respectively; pâ¯<â¯0.001) and bystander-initiated CPR was more frequent (62% vs. 34%, respectively; pâ¯<â¯0.001). CPR by a MICU was less likely in the nursing home than at home - even after adjustment for the patients' and CAs' characteristics (adjusted odds ratio (aOR) [95% confidence interval]â¯=â¯0.49 [0.42-0.57]). A return of spontaneous circulation was less frequent in the nursing home than at home (14% vs. 16%, respectively; ORâ¯=â¯0.86 [0.75-0.99]; pâ¯=â¯0.03) except when CPR was performed by the MICU (31% vs. 26%, respectively; ORâ¯=â¯1.25 [1.07-1.47]; pâ¯=â¯0.005). There was no intergroup difference in the CA outcome at day 30. CONCLUSIONS: Nursing home residents who experience a CA are less likely to receive CPR from a MICU. If CPR is performed, however, the residents' prognosis is no worse than that of patients treated at home.

Out-of-hospital cardiac arrest (OHCA) is considered an important public health issue but its incidence has not been examined in France. The aim of this study is to define the incidence of OHCA in France and to compare this to other neighbouring countries. Data were extracted from the French OHCA registry. Only exhaustive centres during the period from January 1, 2013, to September 30, 2014 were included. All patients were included, regardless of their age and cause of OHCA. The participating centres covered about 10% of the French population. The study involved 6918 OHCA. The median age was 68 years, with 63% of males. Paediatric population (<15years) represented 1.8%. The global incidence of OHCA was 61.5 per 100,000 inhabitants per year in the total population corresponding to approximately 46,000 OHCA per year. In the adult population, we found an incidence of 75.3 cases per 100,000 inhabitants per year. In adults, the incidences were 100.3 and 52.7 in males and females, respectively. Most (75%) OHCA occurred at home and were due to medical causes (88%). Half of medical OHCA had cardiovascular causes. Survival rates at 30 days was 4.9% [4.4; 5.4] and increased to 10.4% [9.1; 11.7] when resuscitation was immediately performed by bystander at patient's collapse. The incidence and survival at 30 days of OHCA in France appeared similar to that reported in other European countries. Compared to other causes of deaths in France, OHCA is one of the most frequent causes, regardless of the initial pathology.

INTRODUCTION: The survival from traumatic vs. medical out-of-hospital cardiac arrest (OHCA) are not yet well described. The objective of this study was to compare survival to hospital discharge and 30-day survival of non-matched and matched traumatic and medical OHCA cohorts. MATERIAL & METHODS: National case-control, multicentre study based on the French national cardiac arrest registry. Following descriptive analysis, we compared survival rates of traumatic and medical cardiac arrest patients after propensity score matching. RESULTS: Compared with medical OHCA (n = 40,878) trauma victims (n = 3209) were younger, more likely to be male and away from home at the time and less likely to be resuscitated. At hospital admission and at 30 days their survival odds were lower (OR: respectively 0.456 [0.353;0.558] and 0.240 [0.186;0.329]). After adjustment the survival odds for traumatic OHCA were 2.4 times lower at admission (OR: 0.416 [0.359;0.482]) and 6 times lower at day 30 (OR: 0.168 [0.117;0.241]). CONCLUSIONS: The survival rates for traumatic OHCA were lower than for medical OHCA, with wider difference in matched vs. non-matched cohorts. Although the probability of survival is lower for trauma victims, the efforts are not futile and pre-hospital resuscitation efforts seem worthwhile.

Extracorporeal CPR is a second line treatment for refractory cardiac arrest, as written in the latest International Guidelines. Optimal timing, patient selection, location and method of implementation vary across the world. The objective here is to present an international consensus on the pillars of an ECPR program. The major aspect the group agrees on in that ECPR should be implemented within 60 minutes of collapse. With this in mind, the program should be built according to local resources knowing that the optimal team will require pre-established specific roles with personnel dedicated to resuscitation and others to ECPR.

BACKGROUND: The survival rate of out-of-hospital cardiac arrest (OHCA) remains extremely low, generally under 10%. Post-resuscitation care, and particularly early coronary reperfusion, may improve this outcome. The main objective of the present study was to determine whether patients with immediate coronary angiography at hospital admission (CAA) had a better outcome than patients without immediate CAA. METHODS: This cohort analysis study was based on data extracted from the French National Cardiac Arrest registry (RéAC). To control for attribution bias, patients were matched using a propensity score, which included age clusters, low flow and no flow delays, initial rhythm and bystander cardiopulmonary resuscitation (CPR). The main endpoint was survival at day 30 (D30). Secondary endpoint was neurological recovery of survivors assessed by the Cerebral Performance Category (CPC) scale, with CPC 1 and 2 at D30 considered as a favorable outcome. RESULTS: From July 1st, 2011 to October 1st, 2016, 63394 OHCA were registered in the database, of which 39444 were of an unknown or suspected cardiac origin. After on-site resuscitation by a mobile medical team, 7584 patients were transported to a hospital facility. Among these patients, 4046 were retained in the analysis after matching for the aforementioned factors and constituted into 2 groups: immediate coronary angiography (iCAA) group (nâ¯=â¯2023) and non-immediate coronary angiography (niCAA) group (nâ¯=â¯2023). The survival rate at D30 after matching was 43.3% in the iCAA group versus 34.5% in the niCAA group (ODâ¯=â¯0.66 [0.58; 0.75], pâ¯<â¯0.001). In the iCAA group, (nâ¯=â¯707) 36% of the patients at D30 were CPC 1-2 comparatively to (nâ¯=â¯539) 27.3% in the niCAA group (pâ¯<â¯0.01). CONCLUSIONS: Both the survival and proportion of patients with favorable neurological recovery were significantly higher in patients who underwent an immediate coronary angiography after a resuscitated OHCA. These observational results warrant further exploration of the benefit of this invasive strategy in randomized studies.

Several classes of medication improve survival in patients with ST-segment elevation myocardial infarction (STEMI). We sought to assess the frequency and effect of an optimal therapy upon discharge according to current international guidelines on 1-year all-cause mortality in a prospective cohort of reperfused patients with STEMI. Using data from the French Reseau Cardiologie Urgence (RESCUe) Network, we studied all patients with STEMI admitted and discharged alive from hospital between 2009 and 2013. Class I and II level guidelines were used to define the optimal therapy (OT) group. The undertreatment (UT) group comprised patients in whom at least 1 drug with a class I recommendation was missing. Multivariable Cox regression analysis with propensity score for the prescription of OT was used. Of the 5,161 patients discharged alive, 2,991 (58%) had OT. The 1-year overall survival rate was 0.99 in the OT group (95% confidence interval [CI] 0.99 to 1.00) versus 0.90 (95% CI 0.88 to 0.92) in the UT group. Patient characteristics in the UT group were worse than those in the OT group. After multivariable adjustment, the association between the OT group and mortality remained significant, with a hazard ratio of 0.12 (95% CI 0.07 to 0.22; p<0.001). Optimal secondary prevention therapy in patients with STEMI discharged alive from hospital remains independently associated with lower 1-year mortality.

BACKGROUND AND PURPOSE: A suboptimal number of ischemic stroke patients eligible for thrombolysis actually receive it, partly because of extended inhospital delays. We developed a comprehensive program designed for emergency unit staff and evaluated its effectiveness for reducing intrahospital times and improving access to thrombolysis. METHODS: We conducted a randomized stepped-wedge controlled trial in 18 emergency unit. The sequentially implemented training intervention, targeting emergency physicians and nurses, was based on specifically designed videos and interactive simulation workshops on intrahospital management optimization. The effectiveness was assessed on intrahospital times and thrombolysis proportion. During the study period, all consecutive patients with confirmed ischemic stroke and no contraindications to thrombolysis were included. RESULTS: A total of 328 patients were enrolled in the control group and 363 in the intervention group. Mean age was 73.6 years. Overall thrombolysis proportion was 34.2% in the intervention group versus 25.6% in the control group (adjusted odds ratio, 1.42; 95% confidence interval, 1.01-2.01), thrombolysis proportion within 4 hours 30 minutes almost doubled (adjusted odds ratio, 1.9; 95% confidence interval, 1.32-2.73). Although imaging-to-stroke unit time was significantly decreased in the intervention group (39 versus 53 minutes; P=0.03), median door-to-imaging and door-to-needle times were not different between groups (P=0.70 and P=0.40, respectively). CONCLUSIONS: An interactive and multifaceted training program targeting emergency professionals was significantly associated with an increased access to thrombolysis, especially within 4 hours and 30 minutes.

BACKGROUND: Although some studies have questioned whether cardiopulmonary resuscitation (CPR) in older people could be futile, age is not considered an essential out-of-hospital cardiac arrest (OHCA) prognostic factor. However, in the daily clinical practice of mobile medical teams (MMTs), age seems to be an important factor affecting OHCA care. AIMS: The purpose of this study was to compare OHCA care and outcomes between young patients (<65 years old) and older patients. METHODS: We performed a case-control study based on data extracted from the French National Cardiac Arrest (CA) registry. All adult patients with CA recorded between July 2011 and May 2014 were included. Each older patient was matched on three criteria: sex, initial cardiac rhythm and no-flow duration. RESULTS: We studied 4347 pairs. We found significantly less basic life support initiation, shorter advanced cardiac life support duration, less MMT automated chest compression, less MMT ventilation and less MMT epinephrine injection in the older patients. Significant differences were also observed for return of spontaneous circulation (odds ratio (OR)=0.84, 95% confidence interval (CI) 0.77-0.92, p<0.001), transport to hospital (OR=0.58, 95% CI 0.51-0.61, p<0.001), vital status at hospital admission (OR=0.55, 95% CI 0.50-0.60, p<0.001) and vital status 30 days after CA (OR=0.42, 95% CI 0.35-0.50, p<0.001). CONCLUSION: All OHCA guidelines, ethical statements and clinical procedures do not propose age as a discrimination criterion in OHCA care. However, in our case-control study, we notice a shorter duration and less intensive care among older patients. This finding may partly explain the lower survival rate compared with younger people.

BACKGROUND: Even if age is not considered the key prognostic factor for survival in cardiac arrest (CA), some studies question whether cardiopulmonary resuscitation (CPR) in the elderly could be futile. OBJECTIVE: The aim of this study was to describe differences in out-of-hospital CA survival rates according to age stratification based on the French National CA registry (RéAC). The second objective was to analyze the differences in resuscitation interventions according to age. METHODS: We performed a retrospective cohort study based on data extracted from the RéAC. All 18,249 elderly patients (>65 years old) with non-traumatic CA recorded between July 2011 and March 2015 were included. Patients' ages were stratified into 5-year increments. RESULTS: Cardiopulmonary resuscitation (CPR) was started significantly more often in younger patients (p = 0.019). Ventilation and automated external defibrillation by bystanders were started without any difference between age subgroups (p = 0.147 and p = 0.123, respectively). No difference in terms of rate of external chest compressions or ventilation initiation was found between the subgroups (p = 0.357 and p = 0.131, respectively). Advanced cardiac life support was started significantly more often in younger patients (p = 0.023). Total CPR duration, return of spontaneous circulation, and survival at hospital admission and at 30 days or hospital discharge decreased significantly with age (p < 10-3). The survival decrease was linear, with a loss of 3% survival chances each 5-year interval. CONCLUSIONS: This study found that survival in older persons decreased linearly by 3% every 5 years. However, this diminished rate of survival could be the consequence of a shorter duration and less advanced life support.

In the past, death was a family and community affair, but today it is institutional and entrusted to healthcare personnel. Thanks to a questionnaire on their feelings about prehospitalisation deaths, the experience and training needs for healthcare personnel at a mobile emergency and intensive care service were analysed. The majority of these professionals had been confronted with difficulties when faced with prehospitalisation deaths. There is little understanding of religious rites, even though this is an important point in dealing with the situation. There is a strong desire for training. The pedagogical support offered in response to the needs expressed was recognised as being useful and should be more widespread.
