Screening problematic use of substances among young subjects attending an emergency department, and subsequent treatment seeking.

INTRODUCTION: Young individuals constitute a key population for the screening of problematic use of substances (PUS), but they are not likely to seek support and are hard to reach. Targeted screening programs should thus be developed in the places of care they may attend for other reasons, including emergency departments (EDs). We aimed to explore the factors associated with PUS in young people attending an ED; we measured the subsequent access to addiction care after ED screening. METHODS: This was a prospective interventional single-arm study which included any individual aged between 16 and 25 years who attended the main ED of Lyon, France. Baseline data were sociodemographic characteristics, PUS status using self-report questionnaires and biological measures, level of psychological health, and history of physical/sexual abuse. Quick medical feedback was provided to the individuals presenting a PUS; they were advised to consult an addiction unit, and contacted by phone at three months to ask whether they had sought treatment. Baseline data were used to compare PUS and non-PUS groups using multivariable logistic regressions, to provide adjusted odds ratios (aORs) and 95% confidence intervals (95% CI), with age, sex, employment status, and family environment as the adjustment variables. The characteristics of PUS subjects who subsequently sought treatment were also assessed using bivariable analyses. RESULTS: In total, 460 participants were included; 320 of whom (69.6%) were presenting current substance use, and 221 (48.0%) with PUS. Compared to non-PUS individuals, PUS ones were more likely to be males (aOR=2.06; 95% CI [1.39-3.07], P<0.001), to be older (per one-year increase: aOR=1.09; 95% CI [1.01-1.17], P<0.05), to have an impaired mental health status (aOR=0.87; 95% CI [0.81-0.94], P<0.001), and to have a history of sexual abuse (aOR=3.33; 95% CI [2.03-5.47], P<0.0001). Only 132 (59.7%) subjects with PUS could be reached by phone at 3 months, among whom only 15 (11.4%) reported having sought treatment. Factors associated with treatment seeking were social isolation (46.7% vs. 19.7%; P=0.019), previous consultation for psychological disorders (93.3% vs. 68.4%; P=0.044), lower mental health score (2.8±1.6 vs. 5.1±2.6; P<0.001), and post-ED hospitalization in a psychiatric unit (73.3% vs. 19.7%; P<0.0001). DISCUSSION/CONCLUSION: EDs are relevant places to screen PUS in youth, but the level of seeking further treatment needs to be substantially improved. Offering systematic screening during an emergency room visit could allow for more appropriate identification and management of youth with PUS.

Assessing patient partnership among emergency departments in France: a cross-sectional study.

OBJECTIVES: This study aims to describe the use of patient partnership, as defined by the Montreal Model, in emergency departments (EDs) in France and report the perception of patient partnership from both the practitioner and patient perspectives. METHODS: This cross-sectional study was conducted between July 2020 and October 2020. First, a survey was sent to 146 heads of EDs in both teaching hospitals and non-teaching hospitals in France to assess the current practices in terms of patient partnership in service organization, research, and teaching. The perceived barriers and facilitators of the implementation of such an approach were also recorded. Then, semi-structured telephone interviews were carried out with patients involved in a service re-organization project. RESULTS: A total of 48 answers (response rate 32.9%) to the survey were received; 33.3% of respondents involved patients in projects relating to service re-organization, 20.8% involved patients in teaching projects, and 4.2% in research projects. Overall, 60.4% of the respondents were willing to involve patients in re-organization or teaching projects. The main barriers mentioned for establishing patient partnership were difficulties regarding patient recruitment and lack of time. The main advantages mentioned were the improvement in patient/caregiver relationship and new ideas to improve healthcare. When interviewed, patients mentioned the desire to improve healthcare and the necessity to involve people with different profiles and backgrounds. A too important personal commitment was the most frequently raised barrier to their engagement. All the patients recognized their positive role, and more generally, the positive role of patient engagement in service re-organization. CONCLUSION: Although this preliminary study indicates a rather positive perception of patient partnership among heads of EDs in France and partner patients, this approach is still not widely applied in practice.

Safety of inter-facility transport strategies for patients referred for severe acute respiratory distress syndrome.

BACKGROUND: Inter-facility transport of patients with acute respiratory distress syndrome (ARDS) in the prone position (PP) is a high-risk situation, compared to other strategies. We aimed to quantify the prevalence of complications during transport in PP, compared to transports with veno-venous extracorporeal membrane oxygenation (VV-ECMO) or in the supine position (SP). METHODS: We performed a retrospective, single center cohort study in Lyon university hospital, France. We included patients ≥ 16 years with ARDS (Berlin definition) transported to an ARDS referral center between 01/12/2016 and 31/12/2021. We compared patients transported in PP, to those transported in SP without VV-ECMO, and those transported with VV-ECMO (in SP), by a multidisciplinary and specialized medical transport team, including an emergency physician and an intensivist. The primary outcome was the rate of transport-related complications (hypoxemia, hypotension, cardiac arrest, cannula or tube dislodgement) in each study groups, compared using a Fisher test. RESULTS: One hundred thirty-four patients were enrolled (median PaO2/FiO2 70 [58-82] mmHg), of which 11 (8%) were transported in PP, 44 (33%) with VV-ECMO, and 79 (59%) in SP. The most frequent risk factor for ARDS in the PP group was bacterial pneumonitis, and viral pneumonitis in the other 2 groups. Transport-related complications occurred in 36% (n = 4) of transports in PP, compared to 39% (n = 30) in SP and 14% (n = 6) with VV-ECMO, respectively (p = 0.33). VV-ECMO implantation after transport was not different between SP and PP patients (n = 7, 64% vs. n = 31, 39%, p = 0.19). CONCLUSIONS: In the context of a specialized multi-disciplinary ARDS transport team, transport-related complication rates were similar between patients transported in PP and SP, while there was a trend of lower rates in patients transported with VV-ECMO.

Relationship between systolic blood pressure and mortality in older vs younger trauma patients - a retrospective multicentre observational study.

BACKGROUND: The population of older trauma patients is increasing. Those patients have heterogeneous presentations and need senior-friendly triaging tools. Systolic blood pressure (SBP) is commonly used to assess injury severity, and some authors advocated adjusting SBP threshold for older patients. We aimed to describe and compare the relationship between mortality and SBP in older trauma patients and their younger counterparts. METHODS: We included patients admitted to three level-I trauma centres and performed logistic regressions with age and SBP to obtain mortality curves. Multivariable Logistic regressions were performed to measure the association between age and mortality at different SBP ranges. Subgroup analyses were conducted for major trauma and severe traumatic brain injury admissions. RESULTS: A total of 47,661 patients were included, among which 12.9% were aged 65-74 years and 27.3% were ≥ 75 years. Overall mortality rates were 3.9%, 8.1%, and 11.7% in the groups aged 16-64, 65-74, and ≥ 75 years, respectively. The relationship between prehospital SBP and mortality was nonlinear (U-shape), mortality increased with each 10 mmHg SBP decrement from 130 to 50 mmHg and each 10-mmHg increment from 150 to 220 mmHg across all age groups. Older patients were at higher odd for mortality in all ranges of SBP. The highest OR in patients aged 65-74 years was 3.67 [95% CI: 2.08-6.45] in the 90-99 mmHg SBP range and 7.92 [95% CI: 5.13-12.23] for those aged ≥ 75 years in the 100-109 mmHg SBP range. CONCLUSION: The relationship between SBP and mortality is nonlinear, regardless of trauma severity and age. Older age was associated with a higher odd of mortality at all SBP points. Future triage tools should therefore consider SBP as a continuous rather than a dichotomized predictor.

[Ethical issues surrounding death in pre-hospital medicine]. / Enjeux et éthique face à la mort en médecine préhospitalière.

Mobile emergency and resuscitation teams are confronted with death on a daily basis. In the home, the management of a death is complex. It raises ethical questions and sometimes destabilizes personal or collective values. Our single-center qualitative survey, conducted over a one-month period (2022), questioned 64/154 caregivers about the moral burden and challenges of such situations. The consequences of operational experience are discussed: time, fatigue, emotions and training. The quality of presence is an alternative to the success or failure of cardiac arrest care at home.

Temporal Trend of Transient Ischemic Attack Management over a 10-Year Period: Data from the Rhône County, France.

BACKGROUND: Timely recognition and management of transient ischemic attack (TIA) offer the greatest opportunity to prevent subsequent stroke. But variability of TIA management quality exists across hospitals. Under the impetus of national plans, measures were adopted to improve TIA management, including a structured local pathway. Our objective was to compare TIA management between two periods over 10 years, before and after the implementation of these measures. METHODS: A before-and-after study was conducted with two identical population-based cohort studies in 2006-2007 (AVC69) and 2015-2016 (STROKE69) including all patients with TIA diagnosis over a 7-month period in six public and private hospitals in the Rhône county in France. The primary outcome was the adequate TIA management defined as brain and vessel imaging within 24 h of admission and the prescription of antithrombotic treatment at discharge. RESULTS: We identified 109 patients TIA patients in 2006-2007, and 458 over the same period in 2015-2016. A higher proportion of patients were adequately managed in 2015-2016 compared to 2006-2007 (14/96 [15%] in 2006-2007 vs. 306/452 [68%] in 2015-2016, p < 0.001). This difference was mainly driven by a marked increase of vessel imaging performed within 24 h of admission, most often by computed tomography angiography. Furthermore, patients called more often emergency medical dispatch before admission, were admitted with a shorter delay after symptom onset, and were more likely discharged to home in 2015-2016 compared to 2006-2007. CONCLUSION: Our study demonstrated an increasing rate of adequate TIA management, mainly driven by a marked increase of vessel imaging within 24 h of admission, over a 10-year period in the Rhône county in France.

Prehospital Tranexamic Acid in Major Pediatric Trauma Within a Physician-Led Emergency Medical Services System: A Multicenter Retrospective Study.

OBJECTIVES: Describe prehospital tranexamic acid (TXA) use and appropriateness within a major trauma pediatric population, and identify the factors associated with its use. DESIGN: Multicenter, retrospective study, 2014-2020. SETTING: Data were extracted from a multicenter French trauma registry including nine trauma centers within a physician-led prehospital emergency medical services (EMS) system. PATIENTS: Patients less than 18 years old were included. Those who did not receive prehospital intervention by a mobile medical team and those with missing data on TXA administration were excluded. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Nine-hundred thirty-four patients (median [interquartile range] age: 14 yr [9-16 yr]) were included, and 68.6% n = 639) were male. Most patients were involved in a road collision (70.2%, n = 656) and suffered a blunt trauma (96.5%; n = 900). Patients receiving TXA (36.6%; n = 342) were older (15 [13-17] vs 12 yr [6-16 yr]) compared with those who did not. Patient severity was higher in the TXA group (Injury Severity Score 14 [9-25] vs 6 [2-13]; p < 0.001). The median dosage was 16 mg/kg (13-19 mg/kg). TXA administration was found in 51.8% cases ( n = 256) among patients with criteria for appropriate use. Conversely, 32.4% of patients ( n = 11) with an isolated severe traumatic brain injury (TBI) also received TXA. Age (odds ratio [OR], 1.2; 95% CI, 1.1-1.2), A and B prehospital severity grade (OR, 7.1; 95% CI, 4.1-12.3 and OR, 4.5; 95% CI, 2.9-6.9 respectively), and year of inclusion (OR, 1.2; 95% CI, 1.1-1.3) were associated with prehospital TXA administration. CONCLUSIONS: In our physician-led prehospital EMS system, TXA is used in a third of severely injured children despite the lack of high-level of evidence. Only half of the population with greater than or equal to one criteria for appropriate TXA use received it. Conversely, TXA was administered in a third of isolated severe TBI. Further research is warranted to clarify TXA indications and to evaluate its impact on mortality and its safety profile to oversee its prescription.

Clinical characteristics and outcome of elderly patients admitted in emergency department with an oxygen mismatch and type 2 myocardial infarction or myocardial injury.

BACKGROUND: Aging is a risk factor for type 2 myocardial infarction or myocardial injury, but few data are available on the elderly. We aimed to determine the factors associated with these pathologies and mortality in the elderly population and its age classes. METHODS: A retrospective cohort of all patients with oxygen mismatch (anemia, hypoxia, tachycardia, hypo/hypertension) for whom a troponin drawn was performed at admission in 2 emergency departments. Medical records were reviewed and classified as having type 2 myocardial infarction, acute or chronic myocardial injury, or no myocardial injury. RESULTS: Of the 824 patients who presented with oxygen mismatch, 675 (81.9%) were older than 65 years. Age over 85 years was a risk factor for acute non-ischemic myocardial injury (odds ratio, 95% confidence interval 2.23, 1.34-3.73). Non-ischemic myocardial injury was associated with hypoxemia, tachycardia, and acute renal failure in those older than 85 years, but only with acute infection in the 75-84-year-old group. Type 2 myocardial infarction was associated only with acute renal failure in the oldest group and, in the 75-84-year-old group, with acute heart failure and shock. Patients older than 85 years with acute myocardial injury, with or without infarction, had a higher in-hospital mortality, but subsequently, mortality depends more on the comorbidities than on age. CONCLUSION: Factors associated with type 2 myocardial infarction and acute non-ischemic myocardial injury in elderly admitted with oxygen mismatch vary notably between age classes. They are associated with in-hospital mortality but not with subsequent mortality when other cormorbities are taken into account.

Rationale, development and implementation of the ReACanROC registry for out-of-hospital cardiac arrests in France and Canada.

France and Canada prehospital systems and care delivery in out-of-hospital cardiac arrests (OHCAs) show substantial differences. This article aims to describe the rationale, design, implementation and expected research implications of the international, population-based, France-Canada registry for OHCAs, namely ReACanROC, which is built from the merging of two nation-wide, population-based, Utstein-style prospectively implemented registries for OHCAs attended to by emergency medical services. Under the supervision of an international steering committee and research network, the ReACanROC dataset will be used to run in-depth analyses on the differences in organisational, practical and geographic predictors of survival after OHCA between France and Canada. ReACanROC is the first Europe-North America registry ever created to meet this goal. To date, it covers close to 80 million people over the two countries, and includes approximately 200 000 cases over a 10-year period.

Characteristics and comparison between e-scooters and bicycle-related trauma: a multicentre cross-sectional analysis of data from a road collision registry.

BACKGROUND: Urban mobility has drastically evolved over the last decade and micromobility rapidly became an expanding segment of contemporary daily transportation routines. E-scooter riders and bicyclists may share similar trauma characteristics, but this has been little explored. The objective was to describe and compare the characteristics of e-scooter and bicycle-related trauma. METHODS: We conducted a cross-sectional analysis of data from the Rhône road collision registry (January 1, 2019 to December 31, 2019). We included all e-scooter or bicycle riders injured in traffic collisions during the study period; there were no exclusion criterion. RESULTS: A total of 2,779 patients were included; 825 (29.7%) were e-scooter riders and 1,954 (70.3%) were bicyclists. E-scooter riders were younger (median [IQR]: 24 [20-32] vs 29 [20-45] years, p < 0.001) and less frequently male (64.2% vs 73.4%, p < 0.001). Most e-scooter and bicycle road collisions were consequent to a fall or loss of vehicle control (74.2% vs 67.7%, p < 0.001). E-scooter riders were less frequently wearing a helmet at the time of the road collision (6.1% vs 30.7%, p < 0.001) and had more frequently head (24.2% vs 19.9%, p = 0.01) and face (30.6 vs 20.5%, p < 0.001) injuries compared to bicyclists. The median injury severity score was 2 [1-4] in both groups with no significant difference (p = 0.77). CONCLUSIONS: E-scooter and bicycle-related trauma patients were mainly young males with minor injuries and most of them sustained a road collision with no third-party. However, they suffered from different injury patterns; e-scooter riders suffered more frequently face and head injuries than bicycle riders, which may be at least partly the consequence of less frequent helmet use among e-scooter riders compared to bicyclists. Hence the two groups of users should not be considered as a single trauma entity. This issue should be promptly addressed to bring down the incidence of preventable injuries and avoid healthcare costs.

Discovering the underlying typology of emergency departments.

BACKGROUND: We hypothesized that monitoring the volume of activity and overall performance indicators is not sufficient to understand the underlying differences between emergency departments. We aimed to understand the underlying common characteristics of emergency departments and map their typology in order to propose adaptive solutions, that would take into account territorial specificities and manage existing resources. METHODS: We applied a multifactorial analysis based on input data at three levels; 1) the health care available in the area surrounding the emergency departments, 2) the level of medical technicality of the hospitals and 3) the profile of emergency department visits. RESULTS: We included 73 emergency departments in this study, representing 93.6% of the emergency departments in our region and seven groups were retained. The smallest group (n = 5) included both public and private structures with low volumes of activity. These medical structures were associated with the shortest length of stay and one of the lowest hospitalisation rates. The largest group (n = 21) included only public structures in peri-urban areas, which were associated with the highest rate of hospitalization in the region. The surrounding population was representative of the regional population, but the patients were older. CONCLUSIONS: This approach represents a systemic response to target the organisational needs and constraints, propose appropriate solutions and adjust the financial resources allocated to hospitals. Future policies to improve care delivery may benefit from stratifying solutions and performance objectives depending on these groups.

Poor Involvement of General Practitioners in Decisions of Withholding or Withdrawing Life-Sustaining Treatment in Emergency Departments.

BACKGROUND: Decisions of withholding or withdrawing life-sustaining treatment are frequent in emergency departments (ED) and patients are often unable to communicate their wishes concerning end of life desires. OBJECTIVE: To evaluate the participation of general practitioners (GPs) during the decision-making process of withholding or withdrawing life-sustaining treatments in ED. DESIGN: Prospective observational multicenter study. PATIENTS: We included patients for whom a decision of withdrawing or withholding life-sustaining treatments was made in ED. For each patient, we enrolled one general practitioner. MAIN MEASURES: GPs were interviewed about their perception of end of life patient's management and the communication with ED and families. KEY RESULTS: There were 109 potential patient participants. We obtained answers from 54 (49.5%) of the patient's associated GPs. Only 4 (7.4%) GPs were involved during the decision-making process of withholding or withdrawing life-sustaining treatments. Among GPs, 29 (53.7%) were contacted by family after the decision, most often to talk about their difficult experience with the decision. A majority (94%) believed their involvements in these decisions were important and 68% wished to "always" participate in end of life decisions despite the fact that they usually don't participate in these decisions. Finally, 66% of GPs believed that management of end of life in the emergency department was a failure and should be anticipated. CONCLUSIONS: GPs would like to be more involved and barriers to GP involvement need to be overcome. We do not have any outcome data to suggest that routine involvement of GPs in all end of life patients improves their outcomes. Moreover, it requires major system and process-based changes to involve all primary care physicians in ED decision-making. NIH TRIAL REGISTRY NUMBER: NCT02844972.

Choice of Initial Brain Imaging in Patients with Suspected Acute Stroke: STROKE69, a Population-Based Study.

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.

Intraosseous Versus Peripheral Intravenous Access During Out-of-Hospital Cardiac Arrest: a Comparison of 30-Day Survival and Neurological Outcome in the French National Registry.

PURPOSE: To compare intraosseous access with peripheral venous access on adults out-of-hospital cardiac arrest (OHCA) patients' clinical outcomes. METHODS: A national retrospective multicentre study was conducted based on the French National Cardiac Arrest Registry. Comparison of patients (intraosseous vs. peripheral venous access) was conducted before and after a matching using a propensity score. The propensity score included confounding factors: age, time between the call (T0) to epinephrine (to take account of how quickly vascular access was achieved), the aetiology of OHCA, the shock and the patient initial rhythm at MMT arrival. RESULTS: A total of 1576 patients received intraosseous access, and 27,280 received peripheral intravenous access. Before matching, OHCA patients with intraosseous access were less likely to survive at all stages (return of spontaneous circulation (ROSC), 0-day survival and 30-day survival). No significant difference in neurological outcome was observed. After propensity score matching, no significant differences in 30-day survival rates (OR = 0.763 [0.473;1.231]) and neurological outcome (OR = 1.296 [0.973;1.726]) were observed. However, intraosseous patients still showed lower likelihood of short-term survival (ROSC and 0-day survival) even after propensity score matching was implemented. CONCLUSION: The populations we investigated were similar to those of other studies suggesting that intraosseous access is associated with reduced survival and poorer neurological outcome. Our findings suggest that intraosseous access is a comparably effective alternative to peripheral intravenous access for treating OHCA patients on matched populations.

A Time-Dependent Propensity Score Matching Approach to Assess Epinephrine Use on Patients Survival Within Out-of-Hospital Cardiac Arrest Care.

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.

Un médiateur dans un service d'urgences hospitalières : quelles missions selon les personnels ?

OBJECTIVES: Violence in emergency services has become a central issue in the daily work of hospital employees. While the use of video surveillance and the training of professionals in conflict management are the most common methods used, there are few cases using the setting up of a third part such as a mediator. We conducted a qualitative study with professionals to examine their representations associated with mediation. METHOD: Semi-directive interviews were conducted with professionals from four emergency units. The topics discussed in interviews were the definition of mediation and the missions that the mediators should fulfil. The content of 38 semi-directive interviews was analysed according to the inductive approach of the grounded theory. A content analysis was made, followed by an analysis aiming to bring out types and convergences/divergences. RESULTS: Professionals were not aware of the definition of mediation and of its missions. They linked to it an instrumental theme, making mediation a tool for conflict prevention and management, a tool for communication with patients about their care, and about the organisation of emergency unit. The upcoming presence of mediators was seen as an help. A potential competition between professionals and mediators in the tasks performed was identified. CONCLUSION: The study shows a favourable opinion towards mediation. It has allowed to identify obstacles to the well-functioning of the missions assigned to mediators. One of the challenges is the integration of this new actor, the mediator.

Comparison of Cone-Beam Computed Tomography and Multislice Computed Tomography in the Assessment of Extremity Fractures.

OBJECTIVES: The aims of this study were to evaluate the agreement between cone-beam computed tomography (CBCT) and multislice computed tomography for the characterization of extremity fractures and to compare image quality, radiation dose, and patient tolerance. METHODS: Thirty-six patients with suspected fracture affecting distal extremities or who required preoperative fracture assessment were enrolled prospectively. Each patient underwent CBCT and multislice computed tomography the same day. Both examinations were evaluated independently twice by 2 trained radiologists using the Müller AO classification for fracture characterization. RESULTS: Cohen κ coefficient for agreement between the imaging techniques was almost perfect for fracture characterization, κ = 0.94 [95% confidence interval, 0.91-0.98]. There was substantial to almost perfect agreement for secondary findings. Cone-beam computed tomography was well tolerated and significantly less irradiant and had better subjective image. CONCLUSIONS: An excellent agreement between both imaging techniques was found. This confirms the ability of CBCT to assess fractures and its potential in the management of patients with distal limb trauma.

Access to treatment among persons with hemophilia: A spatial analysis assessment in the Rhone-Alpes region, France.

OBJECTIVES: In France, only hospital pharmacies can dispense clotting factor concentrates to persons with hemophilia, which limits the access to care for the treatment and the prevention of bleeding episodes. Moreover, the cost of clotting factor concentrates may restrain the maintenance of sufficient stocks in hospital pharmacies. The aim of this study was to investigate the accessibility of clotting factor concentrates to persons with hemophilia in the context of long-term prophylaxis and emergency treatment in the Rhone-Alpes region of France. METHODS: A geographic information system was used for evaluating accessibility of clotting factor concentrates. Persons with hemophilia and hospital pharmacies were geolocalized with the use of postal data, and the evaluation of accessibility was based on the road network. RESULTS: Approximately 72% of the study area was accessible in less than 30 minutes to a hospital pharmacy. Eighty-five percent of persons with hemophilia had access to clotting factor concentrates for prophylactic treatment in less than 20 minutes. Most of them were patients with severe or moderate hemophilia. Regarding emergency doses, factor VIII was accessible in less than 30 minutes in 45.6% of the study area, and factor IX in 30.5%. CONCLUSION: This study highlights that spatial access to clotting factor concentrates by persons with hemophilia in the Rhône-Alpes region is good for prophylactic treatment but is more uneven for emergency doses.
