The aim of this study was to determine the number of annual hospitalizations and overall episodes of care that involve a traumatic brain injury (TBI) by age and gender in the province of Ontario. To provide a more accurate assessment of the prevalence of TBI, episodes of care included visits to the emergency department (ED), as well as admissions to hospital. Mechanisms of injury for overall episodes were also investigated.


Traumatic brain injury cases from fiscal years 2002/03-2006/07 were identified by means of ICD-10 codes. Data were collected from the National Ambulatory Care Reporting System and the Discharge Abstract Database.


The rate of hospitalization was highest for elderly persons over 75 years-of-age. Males generally had higher rates for both hospitalizations and episodes of care than did females. The inclusion of ED visits to hospitalizations had the greatest impact on the rates of TBI in the youngest age groups. Episodes of care for TBI were greatest in youth under the age of 14 and elderly over the age of 85. Falls (41.6%) and being struck by or against an object (31.1%) were the most frequent causes for a TBI.


The study provides estimates for TBI from the only Canadian province that has systematically captured ED visits in a national registry. It shows the importance of tracking ED visits, in addition to hospitalizations, to capture the burden of TBI on the health care system. Prevention strategies should include information on ED visits, particularly for those at younger ages.



Le but de cette étude était de déterminer le nombre annuel d'hospitalisations et de demandes de soins en général motivés par une lésion cérébrale traumatique (LCT) selon l'âge et le sexe dans la province d'Ontario. Afin de fournir une évaluation plus exacte de la prévalence des LCT, les visites à l'urgence et les admissions à l'hôpital ont été comptabilisées comme demandes de soins. Les mécanismes du traumatisme pour tous les épisodes ont également été examinés.


Les cas de LCT survenus au cours des années fiscales 2002/03 - 2006/07 ont été identifiés au moyen des codes CIM-10. Les données ont été tirées du Système national d'information sur les soins ambulatoires et de la Base de données sur les congés des patients.


Le taux d'hospitalisation était plus élevé chez les personnes de plus de 75 ans. Les hommes avaient généralement des taux d'hospitalisations et d'épisodes de soins plus élevés que les femmes. Le fait de comptabiliser les visites à l'urgence avec les hospitalisations avait l'impact le plus grand sur les taux de LCT chez les groupes d'âges inférieurs. Les épisodes de soins pour LCT étaient plus élevés chez les jeunes de moins de 14 ans et chez les gens âgés de plus de 85 ans. Les chutes (41,6%) et le fait d'être frappé par ou contre un objet (31,1%) étaient les causes les plus fréquentes de LCT.


Cette étude fournit des estimés de LCT dans la seule province canadienne qui inscrit a systématiquement les visites à l'urgence dans un registre nationale. Elle montre l'importance de faire le suivi des visites à l'urgence en plus des hospitalisations pour apprécier le fardeau que constitue la LCT sur le système de santé. Les stratégies de prévention devraient mentionner l'information sur les visites à l'urgence, particulièrement chez les jeunes.
