BACKGROUND
In April of 2012, Michigan repealed its 35-year-old universal motorcycle helmet law in favor of a partial helmet law, which permits motorcyclists older than 21 years old with sufficient insurance and experience to drive un-helmeted. We evaluated the clinical impact of the repeal.
METHODS
The Michigan Trauma Quality Improvement Program's trauma database was queried for motorcycle crash patients between 1/1/09-4/12/12 and between 4/13/12-12/31/14.
RESULTS
There were 1970 patients in the pre-repeal analysis and 2673 patients in the post-repeal analysis. Following the repeal, patients were more likely to be un-helmeted (p < 0.001) and to have a traumatic brain injury (p < 0.001). Patients were also more likely to require neurosurgical interventions (relative risk 1.4, p = 0.011).
CONCLUSION
Following the repeal of the universal helmet law, there has been a significant increase in traumatic brain injuries and neurosurgical interventions. This analysis highlights another detrimental impact of the repeal of the universal helmet law.
背景
2012 年 4 月，密歇根州废除了其 35 年历史的通用摩托车头盔法，转而实施部分头盔法，允许 21 岁以上、有足够保险和经验的摩托车手不戴头盔驾驶。我们评估了该法规废除的临床影响。
方法
密歇根创伤质量改进计划的创伤数据库被查询了 2009 年 1 月 1 日至 2012 年 4 月 12 日以及 2012 年 4 月 13 日至 2014 年 12 月 31 日之间的摩托车事故患者。
结果
在废除前的分析中有 1970 名患者，在废除后的分析中有 2673 名患者。废除后，患者更有可能不戴头盔（p<0.001）且更有可能患有创伤性脑损伤（p<0.001）。患者也更有可能需要神经外科干预（相对风险 1.4，p=0.011）。
结论
通用头盔法废除后，创伤性脑损伤和神经外科干预显著增加。这项分析突出了通用头盔法废除的另一个不利影响。
