Abstract:We have previously shown that mild HIV-related neuropsychological (NP) dysfunction is associated with both poor performance on a driving simulator and worse driving record (more real-life accidents). This study examines (1) whether HIV-related NP deficits result in unsafe driving (evaluated via an on-road assessment) and (2) the utility of NP and simulator assessments in identifying unsafe drivers. Methods: Participants (36 HIV+, 20 HIV-) completed an NP battery and were classified as impaired or not. Driving skills were assessed by (1) performance on two simulations, and (2) a 30-min on-road evaluation by a rehabilitation driving instructor. The instructor determined whether subjects were safe to be driving, All evaluators were blinded to subject serostatus and results on all other tests. Results: Ten (28%) of the HIV+ participants were classified as NP impaired (none with greater than a mild-to-moderate level of impairment). Although it was rare for HIV seronegative and HIV- NP normals to be considered unsafe on the road (5% and 7.7%, respectively), 4 of 10 participants (40%) with HIV-related NP dysfunction were so classified. NP impaired participants also did more poorly on each of the simulations. NP and simulator performance were each significant predictors of on-road failure. Conclusion: Even mild levels of HIV-associated cognitive impairment may result in impaired driving skills in a subset of individuals. Further study is needed to refine the use of NP and other predictors for identifying individuals at risk for dangerous driving behaviors.
