Various reports have suggested that epidemiological patterns of Traumatic Brain Injury (TBI) are changing in high-income countries, but the evidence to support this is often indirect and only a few longitudinal studies exist. We aimed to explore epidemiological patterns of TBI in Belgium over a 10-year period.
A retrospective analysis of Minimum Hospital Data provided by Statistics Belgium was performed for the period 2003-2012. ICD-9 classification was used to identify TBI and to differentiate subtypes. The annual incidence of hospital admissions and in-hospital mortality rates were calculated and further differentiated for age, gender and cause of injury.
The age-adjusted incidence of hospital admissions decreased by 3.6% per year. An increase in the number of elderly patients with TBI and a decrease in the younger age groups were found. Falls now represent the main cause of TBI. A mortality rate of 6.5 per 100,000 population per year was found and did not change significantly over time.
This longitudinal study confirms that epidemiological patterns in TBI are changing: overall incidence is steadily decreasing, but in elderly patients, the incidence is increasing. Falls are the leading cause, occurring most frequently in elderly patients. These changes are relevant for prevention.
各种报告表明，高收入国家创伤性脑损伤（TBI）的流行病学模式正在发生变化，但支持这一观点的证据往往是间接的，且仅有少数纵向研究。我们旨在探讨比利时10年间TBI的流行病学模式。
对2003年至2012年期间比利时统计局提供的最低限度医院数据进行回顾性分析。采用国际疾病分类第九版（ICD-9）进行分类以识别TBI并区分亚型。计算医院入院的年发病率和住院死亡率，并按年龄、性别和损伤原因进一步区分。
年龄调整后的医院入院发病率每年下降3.6%。发现TBI老年患者数量增加，而年轻年龄组患者数量减少。跌倒现在是TBI的主要原因。发现每年每10万人口的死亡率为6.5，且随时间没有显著变化。
这项纵向研究证实TBI的流行病学模式正在发生变化：总体发病率在稳步下降，但老年患者的发病率在上升。跌倒是主要原因，在老年患者中最常发生。这些变化与预防相关。
