Oregon enacted a law in 2002 that requires some health care practitioners to report cognitively impaired drivers to the Department of Motor Vehicles. We examined reports submitted between 2003 and 2006 on 1664 potential impaired drivers. Of reported drivers, 48% were older than 80 years of age. Reports of cognitive impairment were 7 times more common than functional impairments. The most common cognitive impairments were judgment and problem solving (65%), memory (53%), and reaction time (52%). Only 10% of suspended drivers regained their driving privileges. Drivers older than 80 years of age were 6 times less likely to regain privileges compared to drivers 59 years or younger. In summary, Oregon's law resulted in loss of driving privileges in a small number of licensed drivers. Over half were aged 80 years or older, with chronic or progressive cognitive impairments. Further study is needed to determine whether this law reduces crashes and crash-related fatalities.
俄勒冈州于2002年颁布了一项法律，要求一些医疗从业者向机动车管理部门报告认知功能受损的驾驶员。我们研究了2003年至2006年期间提交的关于1664名潜在受损驾驶员的报告。在报告的驾驶员中，48%的年龄超过80岁。认知障碍的报告比功能障碍的报告常见7倍。最常见的认知障碍是判断力和解决问题的能力（65%）、记忆力（53%）和反应时间（52%）。只有10%被吊销驾驶特权的驾驶员恢复了其驾驶特权。与59岁及以下的驾驶员相比，80岁以上的驾驶员恢复特权的可能性要低6倍。总之，俄勒冈州的这项法律导致少数持照驾驶员失去了驾驶特权。其中一半以上年龄在80岁及以上，患有慢性或进行性认知障碍。需要进一步研究以确定这项法律是否能减少撞车事故及与撞车相关的死亡人数。
