- Abstract: Background: Transient ischemic attack (TIA) and minor stroke are associated with a substantial risk of subsequent stroke; however, there is uncertainty about whether such patients require admission to hospital for their initial management. We used data from a clinical stroke registry to determine the frequency and predictors of hospitalization for TIA or minor stroke across the province of Ontario, Canada. Methods: The Ontario Stroke Registry collects information on a population-based sample of all patients seen in the emergency department with acute stroke or TIA in Ontario. We identified patients with minor ischemic stroke or TIA included in the registry between April 1, 2008, and March 31, 2011, and used multivariable analyses to evaluate predictors of hospitalization. Results: Our study sample included 8540 patients with minor ischemic stroke or TIA, 47.2% of whom were admitted to hospital, with a range of 37.6% to 70.3% across Ontario's 14 local health integration network regions. Key predictors of admission were preadmission disability, vascular risk factors, presentation with weakness, speech disturbance or prolonged/persistent symptoms, arrival by ambulance, and presentation on a weekend or during periods of emergency department overcrowding. Conclusions: More than one-half of patients with minor stroke or TIA were not admitted to the hospital, and there were wide regional variations in admission patterns. Additional work is needed to provide guidance toAbstract: Background: Transient ischemic attack (TIA) and minor stroke are associated with a substantial risk of subsequent stroke; however, there is uncertainty about whether such patients require admission to hospital for their initial management.

RÉSUMÉ: Variables prédictives d'hospitalisation chez des patients victimes d'une ischémie cérébrale transitoire ou d'un AVC mineur. Contexte: Une ischémie cérébrale transitoire (ICT) et un AVC mineur sont associés au risque notable d'être victime d'un autre AVC. Il subsiste cependant des doutes quant à la nécessité d'hospitaliser des patients pour un suivi initial. Nous avons donc utilisé les données d'un registre clinique concernant les AVC pour déterminer la fréquence et les variables prédictives d'une hospitalisation à la suite d'une ICT ou d'un AVC mineur partout en Ontario (Canada). Méthodes: Le Registre de l'AVC de l'Ontario recueille des données au sein d'un échantillon représentatif composé de tous les patients examinés dans un service d'urgence ontarien à la suite d'un ICT ou d'un AVC mineur. Nous avons ainsi identifié les patients victimes d'une ICT et d'un AVC mineur inclus dans le registre entre le 1er avril 2008 et le 31 mars 2011. Nous avons ensuite procédé à des analyses multi-variables afin d'évaluer les variables prédictives d'une hospitalisation. Résultats: L'échantillon visé par notre étude incluait 8540 patients victimes d'une ICT ou d'un AVC mineur ; sur ce total, 47, 2 % ont été hospitalisés, les pourcentages variant de 37, 6 % à 70, 3 % dans les 14 Réseaux locaux d'intégration des services de santé (RLISS) de l'Ontario. Les principales variables prédictives d'une hospitalisation se sont révélées être un handicap antérieur à cette hospitalisation, des facteurs de risque vasculaire, des signes de faiblesse, des troubles de la parole ou des symptômes persistants et prolongés de ces troubles, une arrivée en ambulance et une visite à l'hôpital les fins de semaine ou lorsque les services d'urgence sont encombrés. Conclusions: Plus de la moitié des patients victimes d'un AVC mineur ou d'une ICT n'a pas été hospitalisée. Qui plus est, on peut noter de fortes variations régionales en ce qui regarde la tendance à l'hospitalisation. Il est aussi nécessaire de fournir au personnel de la santé des lignes directrices pour savoir s'il est nécessaire ou non d'hospitaliser tels patients et si ceux ayant obtenu leur congé bénéficient d'un suivi adéquat. … (more)
