Impact of the Thrombectomy Trials on the Management and Outcome of Large Vessel Stroke: Data From the Lyon Stroke Center

Introduction: Randomized trials (RT) have recently validated the superiority of thrombectomy over standard medical care, including intravenous thrombolysis (IVT). However, data on their impact on routine clinical care remains scarce.Methods: Using a prospective observational registry, we assessed: (1) the clinical and radiological characteristics of all consecutive patients treated with thrombectomy; (2) the outcome of all patients with M1 occlusion (treated with thrombectomy or IVT alone). Two periods were compared: before (2013–2014) and after (2015–2016) the publication of RT.Results: Endovascular procedures significantly increased between the two periods (N = 82 vs. 314, p < 0.0001). In 2015–2016, patients were older (median [IQR]: 69 [57-80]; vs. 66 [53-74]; p = 0.008), had shorter door-to-clot times (69 [47-95]; vs. 110 [83-155]; p < 0.0001) resulting in a trend toward shorter delay from symptom onset to reperfusion (232 [185-300]; vs. 250 [200-339]; p = 0.1), with higher rates of reperfusion (71 vs. 48%; p = 0.0001). Conversely, no significant differences in baseline NIHSS scores, ASPECTS, delay to IVT or intracranial hemorrhage were found. In 2015–2016, patients with M1 occlusion were treated with thrombectomy more often than in 2013–2014 (87 vs. 32%, respectively; p < 0.0001), with a significant improvement in clinical outcome (shift analysis, lower modified Rankin scale scores: OR = 1.68; 95% CI: 1.10–2.57; p = 0.017).Conclusion: Following the publication of RT, thrombectomy was rapidly implemented with significant improvements in intrahospital delay and reperfusion rates. Treatment with thrombectomy increased with better clinical outcomes in patients with M1 occlusion

Performance of acute stroke management

L'accès aux thérapeutiques de reperfusion (thrombolyse/thrombectomie) dans les délais recommandés constitue l'enjeu principal de la prise en charge de l'accident vasculaire cérébral (AVC) à la phase aiguë. Actuellement, seuls 20% des patients éligibles en bénéficient, en raison de difficultés à identifier l'AVC et de délais de prise en charge prolongés. La filière de soins optimale pour l'AVC à la phase aiguë comprend l'appel au 15 dès la survenue des symptômes et un transfert direct du patient en unité neurovasculaire (UNV). Cependant, une 1ère étude menée dans le Rhône en 2006-2007 (AVC 69) avait objectivé que la filière de soins passait par les urgences dans 80% des cas et que seuls 10% des patients éligibles étaient thrombolysés. Les principaux retards identifiés dans la prise en charge concernaient au niveau préhospitalier, l'identification de l'AVC et l'appel au 15 par le patient ou les témoins, et au niveau intrahospitalier, le parcours de soins dans les services d'urgences, l'obtention de l'imagerie cérébrale et le transfert en UNV. Pour répondre à ces problématiques, nous avons mis en place un programme visant à améliorer la prise en charge de l'AVC en région Rhône-Alpes. Notre travail de thèse rapporte 3 projets menés au sein de ce programme : Le premier projet ciblait la phase préhospitalière. Il a permis d'évaluer la perception de l'AVC au sein de la population générale, afin de proposer une campagne d'information pertinente. Nous avons étudié l'impact de cette campagne dans le Rhône sur l'appel au 15 et les connaissances de la population sur l'AVC. Le second projet a évalué une intervention multifacettes de formation des professionnels des services d'urgences dont l'objectif était de diminuer les délais de prise en charge intrahospitaliers et améliorer l'accès à la thrombolyse. Le troisième projet a porté sur l'étude de la validité des bases de données médico-administratives hospitalières pour identifier les AVC, en vue de l'utilisation de ces bases à des fins épidémiologiques ou pour la construction d'indicateurs de suivi de la performance. Les interventions déployées au sein du programme ont permis d'améliorer le recours à l'appel au 15 et le taux de thrombolyse, néanmoins l'ampleur des effets observés reste limitée et aucun effet sur les délais n'a pu être mis en évidence. Un approfondissement des mécanismes d'action des interventions est nécessaire pour pouvoir proposer des interventions plus efficacesThe main issue in the management of acute stroke is access to reperfusion strategies (ie thrombolysis or thrombectomy) within the recommended time window. Currently, fewer than 1 in 2 eligible patients are receiving this treatment, partly because of difficulties in stoke identification and extended treatment delays. The optimal care pathway for acute stroke includes immediately calling emergency medical services (EMS) at symptoms onset followed by a direct transfer to the stroke unit (SU). However, a previous study carried out in 2006-2007 in the Rhône region (AVC69) pointed out that 80% of patients were managed in the emergency unit and only 10% of eligible patients were thrombolysed. Delays in management were identified at different stages: at the prehospital level, for stroke identification and the EMS call, and at the inhospital level with inefficicent processes in emergency units, delays in cerebral imaging obtaining and for SU transfert. To address these problems, we have set up a program to improve stroke management in the Rhône-Alpes region. Our work reports 3 projects carried out within this program: The first project identified stroke representations in the general population in order to design a relevant information campaign. Then, we studied the impact of this campaign on the number of EMS call for stroke suspicion and on population's knowledge about stroke. In the second project, we developed and evaluated a multifaceted training intervention for emergency units professionals aimed at reducing inhospital management times and improving access to thrombolysis. The third project analyzed the validity of hospital medico-administrative databases to identify strokes, in anticipation of the use of these databases for epidemiological studies or for the construction of performance indicators. Interventions within the program improved the EMS call and thrombolysis rate, but the magnitude of observed effects remained limited and no effect on management times could be observed. A deeper understanding of the mechanisms of intervention is needed to further design more effective intervention

Who maintains good mental health in a locked-down country? A French nationwide online survey of 11,391 participants

International audienceLockdown measures can differentially affect mental wellbeing in populations depending on individual determinants. We aim to investigate the sociodemographic and environmental determinants of wellbeing on the French population during lockdown due to the SARS-CoV-2 pandemic with an online survey. Among 11,391 participants who completed the questionnaire, various factors negatively impacted wellbeing: being a female, a student, disabled, having no access to outdoor spaces, or living in a small home. Conversely, being employed and having more social contacts had a positive impact. During lockdowns, authorities should consider the vulnerability of specific populations, especially when they live in constrained housing conditions

Using patient comments from a standardised experience survey to investigate their perceptions and prioritise improvement actions: a thematic and syntactic analysis

Abstract Background Although patient experience surveys flourish in many countries with the aim to improve quality of care, questions remain concerning their ability to become effective drivers of change within institutions. The patient comments from the French national patient experience hospital survey were analysed using an innovative structured approach to characterise patient experience and identify field actions for the institutions. Methods The comments were taken from the two open-ended questions comprised in the patient experience survey of the Hospices Civils de Lyon between 2018 and 2019. The comments analysis methodology consisted in three steps: thematic analysis; syntactic analysis; generation of statistics for the creation of a patient journey and prioritisation of sub-themes. The STROBE statement checklist was followed. Results Over a year, 79.7% of the 7 362 respondents left at least one comment at the end of the survey and were included in the study, for a total of 5 868 surveys and 10 061 comments. These led to the identification of 28 general themes and 184 specific sub-themes. From the patient journey created, 23 sub-themes were prioritised and gathered into four key categories: relationship between patient and staff; environment; surgery and pain management; information and care coordination. For each of them, the actions and expectations formulated by the respondents were described. Conclusions The analysis of patient comments obtained from a standardised survey allowed to characterise the patient journey using data that describes patient experience, enabling a prioritisation of actions aiming to improve practice and quality of care at the institution, department, and staff level

PLAN-e-PSY, a mobile application to improve case management and patient’s functioning in first episode psychosis: protocol for an open-label, multicentre, superiority, randomised controlled trial

International audienceIntroduction: The prognosis of first episode psychosis (FEP), which is a severe disorder, can be notably impaired by patients' disengagement from healthcare providers. Coordinated specialty care with case management is now considered as the gold standard in this population, but there are still challenges for engagement with subsequent functional impairments. Youth-friendly and patient-centred clinical approaches are sought to improve engagement in patients with FEP. Mobile applications are widely used by young people, including patients with FEP, and can increase the youth friendliness of clinical tools. We hypothesise that a co-designed mobile application used during case management can improve functioning in patients with FEP as compared with usual case management practices.Methods and analysis: A mobile case management application for planning and monitoring individualised care objectives will be co-designed with patients, caregivers and health professionals in a recovery-oriented approach. The application will be compared with usual case management practices in a multicentre, two-arm and parallel groups clinical trial. Patients will be recruited by specialised FEP teams. Impact on functioning will be assessed using the Personal and Social Performance Scale; the variation between baseline and 12 months in each group (control and active) will be the primary outcome.Ethics and dissemination: This study has been approved by the Inserm Institutional Review Board IRB00003888 (Comité d'évaluation éthique de l'INSERM, reference number 20-647). The results of the study will be published in a peer-reviewed journal and presented at national and international conferences. We will also communicate the results to patients and family representatives' associations. An optimised version of the application will be then disseminated through the French FEP network (Transition Network).Trial registration number: ClinicalTrials.gov: NCT04657380
