To relate the standardized road test to video recordings of naturalistic driving in older adults with a range of cognitive impairment.
Cross-sectional observational study.
Academic medical center memory disorders clinic.
One hundred three older drivers (44 healthy, 59 with cognitive impairment) who passed a road test.
Error rate and global ratings of safety (pass with and without recommendations, marginal with restrictions or training, or fail) made by a professional driving instructor.
There was fair agreement between global ratings on the road test and naturalistic driving. More errors were detected in the naturalistic environment, but this did not affect global ratings. Error scores between settings were significantly correlated, and the types of errors made were similar. History of crashes corrected for miles driven per week was related to road test error scores but not naturalistic driving error scores. Global cognition (Mini-Mental State Examination) was correlated with road test and naturalistic driving errors. In healthy older adults, younger age was correlated with fewer errors on the road test and more errors in naturalistic driving.
Road test performance is a reasonable proxy for estimating fitness to drive in older individuals' typical driving environments, but differences between performance assessed using these two methods remain poorly understood and deserve further study.
将标准化的道路测试与认知障碍程度不同的老年人的自然驾驶视频记录相关联。
横断面观察性研究。
学术医疗中心记忆障碍诊所。
103 名通过道路测试的老年驾驶员（44 名健康，59 名认知障碍）。
专业驾驶指导员的错误率和安全性总体评分（通过且无建议、勉强通过但有限制或培训、不通过）。
道路测试和自然驾驶的总体评分之间存在良好的一致性。在自然环境中检测到更多的错误，但这并没有影响总体评分。两种设置下的错误分数显著相关，且错误类型相似。校正每周行驶里程后的事故史与道路测试错误分数相关，但与自然驾驶错误分数无关。总体认知（简易精神状态检查）与道路测试和自然驾驶错误相关。在健康的老年人中，年龄较小与道路测试错误较少和自然驾驶错误较多相关。
道路测试表现是评估老年人在典型驾驶环境中驾驶能力的合理指标，但这两种方法评估的性能之间的差异仍不清楚，值得进一步研究。
