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.
本研究旨在确定安大略省按年龄和性别划分的因创伤性脑损伤（TBI）而导致的年住院次数和总护理次数。为了更准确地评估 TBI 的患病率，护理次数包括急诊部（ED）就诊和住院治疗。还研究了总体损伤机制。
通过 ICD-10 代码确定 2002/03 财年至 2006/07 财年的 TBI 病例。数据来自国家门诊护理报告系统和出院摘要数据库。
75 岁以上的老年人住院率最高。男性的住院和护理次数普遍高于女性。将 ED 就诊纳入住院治疗对年龄最小的人群的 TBI 发生率影响最大。14 岁以下和 85 岁以上的 TBI 护理次数最多。跌倒（41.6%）和被物体撞击或撞击（31.1%）是 TBI 的最常见原因。
该研究提供了加拿大唯一系统性地在国家登记处记录 ED 就诊的省份的 TBI 估计数。它表明，除了住院治疗外，还应跟踪 ED 就诊，以了解 TBI 对医疗保健系统的负担。预防策略应包括有关 ED 就诊的信息，特别是针对年轻人群。
