BACKGROUND Traumatic Brain Injury (TBI) is a serious hidden health issue disproportionately affecting people who experience incarceration. OBJECTIVE We examined the association between TBI and serious disciplinary charges among men and women sentenced by the courts to terms of two or more years. METHODS The study originated in Ontario, Canada and used linked administrative health and correctional data. The cohort included adults experiencing their first federal sentence between 1998 and 2011 (N = 12,038). We examined disciplinary charges incurred 2 years post-sentence commencement. TBI was defined using the International Classification of Diseases (ICD-9 and ICD-10) diagnostic codes. Robust Poisson regression was conducted to assess the association between TBI and disciplinary charges. FINDINGS The prevalence of TBI for the full sample was 13.2%. One-third of adults with a recent TBI had a serious disciplinary charge. The unadjusted risk of incurring a serious charge for those with a history of TBI was 39% higher than those with no history of TBI (CI: 1.29-1.49). The adjusted risk was 1.14 (CI: 1.06-1.22). CONCLUSIONS TBI is a serious health concern that makes it difficult for incarcerants to adjust to prison. Additional support/resources are needed to support those with histories of TBI.

脑外伤与监狱指控之间的关联：一项基于人群的队列研究。

背景技术创伤性脑损伤（TBI）是严重的隐藏的健康问题，其不成比例地影响经历监禁的人。目的我们研究了TBI与法院判处两年或更长时间的男女严重纪律指控之间的关系。方法该研究起源于加拿大安大略省，并使用了相关的行政健康和惩戒数据。该队列包括成年人，他们在1998年至2011年之间经历了第一次联邦判决（N = 12,038）。我们检查了从判决开始2年内产生的纪律处分。TBI是使用国际疾病分类（ICD-9和ICD-10）诊断代码定义的。进行了稳健的Poisson回归以评估TBI和纪律指控之间的关联。结果整个样本的TBI患病率为13。2％。近期患有TBI的成年人中有三分之一受到了严重的纪律处分。具有TBI病史的患者未经调整的产生严重费用的风险比没有TBI病史的患者高39％（CI：1.29-1.49）。调整后的风险为1.14（CI：1.06-1.22）。结论TBI是一个严重的健康问题，使被拘留者很难适应监狱。需要额外的支持/资源来支持那些有TBI历史的人。
