Older drivers with cognitive impairment (CI)/dementia make significantly more driving errors than healthy controls; however, whether driving errors are predictive of pass/fail outcomes in older drivers with CI/dementia are unclear. This study determined the driving errors that predicted failing an on-road assessment in drivers with CI. We retrospectively collected comprehensive driving evaluation data of 80 participants (76.1 ± 9.3 years) from an Ontario driving assessment center. Adjustment to stimuli (area under the curve [AUC] = 0.88), lane maintenance (AUC = 0.84), and speed regulation errors (AUC = 0.85) strongly predicted pass/fail outcomes. Worse performance on the Trails B (time) and Useful Field of View® (Subtest 2, Subtest 3, and risk index) were significantly correlated with adjustment to stimuli ( < .05), lane maintenance ( < .05), and speed regulation errors ( < .05). Adjustment to stimuli, lane maintenance, and speed regulation errors may be critical indicators of failing an on-road assessment in older drivers with CI. Prioritizing these errors may help identify at-risk drivers.
认知障碍（CI）/痴呆症的老年驾驶员比健康对照组犯更多的驾驶错误；然而，CI/痴呆症的老年驾驶员的驾驶错误是否能预测通过/失败的结果尚不清楚。本研究旨在确定导致 CI 驾驶员路考失败的驾驶错误。我们回顾性地收集了安大略省驾驶评估中心 80 名参与者（76.1±9.3 岁）的全面驾驶评估数据。对刺激的调整（曲线下面积 [AUC] = 0.88）、车道保持（AUC = 0.84）和速度调节错误（AUC = 0.85）强烈预测了通过/失败的结果。Trails B（时间）和有用视野®（分测验 2、分测验 3 和风险指数）的表现更差与对刺激的调整（<0.05）、车道保持（<0.05）和速度调节错误（<0.05）显著相关。对刺激的调整、车道保持和速度调节错误可能是 CI 老年驾驶员路考失败的关键指标。优先考虑这些错误可能有助于识别高危驾驶员。
