Abstract

OBJECTIVES: To evaluate the ability to predict on-road driving in cognitively impaired older drivers.

DESIGN: Cross-sectional observational study. SETTING: Laboratory tests and on-road assessment. PARTICIPANTS: Drivers with cognitive impairment (Mini-Mental State Examination score < 26, N = 43, mean age 74). MEASUREMENTS: The Roadwise Review, a hazard perception test (HPT), several vision tests, and a standardized 18-km driving assessment.

RESULTS: The best prediction of passing or failing the on-road test was a combination of the HPT, leg strength, visual acuity, visual search and working memory, and number of medications taken (Nagelkerke coefficient of determination = 0.40). The sensitivity of the model was 71%, and the specificity was 75%.

CONCLUSION: Further research is required to determine how these tests may be used or combined with other data (e.g., medical history) to assess fitness to drive of cognitively impaired older drivers.
