Background and Purpose: When an ischaemic stroke due to a large vessel occlusion occurs, the sooner Mechanical Thrombectomy (MT) is performed, the better the functional prognosis. However, the organisation of care does not systematically allow rapid access to MT. The aim of our study was to determine the clinical and organisational factors associated with the time to access to MT., Methods: We conducted a cohort study in Gironde County, France. Patients admitted for MT and regulated by the Gironde Emergency Medical Services (EMS) between 01/01/2017 and 31/12/2018 were included. The time to access to MT was the difference between the first call to EMS and groin puncture for MT. The main explanatory variables were: type of pathway (mothership (MS), drip and ship (DS) with cerebral imaging performed in the local hospital centre (LHC), and DS without imaging in the LHC); NIHSS score; driving distance to MT; time of stroke onset (weekend or holiday, school holidays, other); age and sex. Linear regression models were used to explain time to access to MT. Missing data were handled using a multiple imputation procedure (Full conditional specification, Mice R-Package) carried out in our multivariable linear regression model. A quantitative bias analysis was performed by weighing the imputed time to access to MT and identifying the weight changing the conclusions of our analysis., Results: Among the 314 included patients, 152 were women (48.4%), and the mean NIHSS score was 16.4. Two hundred and two (64.3%) patients were managed through the MS pathway. The average time from onset to femoral puncture was 251 minutes. In the multivariate analysis, the time to MT was longer when patients were managed DS with imaging in the LHC pathway (+106 min, p = 0.03), and even longer in the DS without imaging in the LHC pathway (+197 min, p = 0.002), compared with MS. Time from onset to MT decreased with increasing NIHSS score (-6 min per NIHSS point, p <.0001). In our quantitative bias analysis, we multiplied the imputed time in access to MT in the DS pathways only (with or without imaging in the LHC) by weights varying from 0.9 to 0.2 (imputed delays reduced from 10% to 80%). With reduction of 40% or more, there was no longer any difference in time to access to MT between the three studied pathways., Conclusions: The DS pathway can be shortened by generalizing access to cerebral imaging in LHCs. Optimizing pre-admission orientation toward MT is a major issue in LVOS management., Competing Interests: Declaration of Conflicting Interests statement The Authors declare no conflict of interest., (Copyright © 2022 Elsevier Masson SAS.

Ischemic stroke accounts for 80% of overall stroke, and is one of the leading causes of death, disability and dementia in worldwide. Management of patients with acute ischemic stroke dramatically improved over time with the implementation of intensive care stroke units, the development of acute recanalization strategies, the optimization of the management of post-stroke complications, and the prevention of early stroke recurrence. The objective of this article is to provide a general overview of the current management of patients with acute ischemic stroke aiming at improving post-stroke outcome., (Copyright © 2021 Société Nationale Française de Médecine Interne (SNFMI).

Background: Activity-based Funding can induce financial imbalances for health institutions if innovative medical devices (MD) used to perform acts are included in Diagnosis Related Groups (DRG) tariff. To be reimbursed in addition to the DRG tariff, innovative MD must have received a favorable evaluation by the French National Authority for Health (Haute Autorité de Santé) and be registered on the positive list. The aim of this study was to evaluate the expenses and incomes generated by each scenario (before and after the reimbursement of MD), and the financial reports. This study concerned the management of ischemic stroke by mechanical thrombectomy devices, in high-volume French hospital., Methods: All patients who have had an acute ischemic stroke and admitted to the interventional neuroradiology unit between January 2016 and December 2017 were included retrospectively in this monocentric study. They were divided into four subgroups based on the severity of the DRG. The cost study was carried out using the French National Cost Study Methodology adjusted for the duration of the stays and by micro-costing on MD., Results: A total of 267 patients were included. Over the study period, the average cost of the hospital stay was €10,492±6364 for a refund of €9838±6749 per patient. The acts performed became profitable once the MD were registered on the positive list (€-1017±3551 vs. €560±2671; P<0.05). Despite this reimbursement, this activity remained in deficit for DRG lowest severity (level 1) patients (€-492±1244). Specific MD used for mechanical thrombectomy represented 37% of the total cost of stay., Conclusion: The time required to evaluate MD reimbursement files is too long compared to their development. As a result, practitioners are in difficulty to be able to carry out acts according to the consensual practices of their learned societies, without causing any financial deficit of their institutions., (Copyright © 2019 Elsevier Masson SAS.

Cerebral infarction (CI) is caused by intracranial artery occlusion. The main treatment approach is recanalisation, which is performed either medically, by intravenous thrombolysis within 4 hours and a half of the event, or by mechanical thrombectomy, which is possible up to 24 hours after CI., (Copyright © 2018 Elsevier Masson SAS.

Acute management of ischemic stroke is a burning topic in 2017 since stroke represents the leading cause of acquired handicap in adults. Over the last past years, major improvement took place, especially with the demonstration of the efficacy of mechanical thrombectomy, thus needing to better organize care pathways, and optimize access to neurologists and interventional neuroradiology platforms. Intensive care stroke units remain the pivotal place of patients' management. A multidisciplinary coordination is required, with continuous teaching of all the actors involved in stroke management, so as to increase the number of patients who could benefit from available active treatments., (Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).
