A study was made to determine whether HIV-infected patients with prolonged virological control suffer subclinical neurocognitive problems capable of interfering with driving skills, compared with the general population, and to explore the possible existence of differences between those treated with and without efavirenz. Material and Methods: We included 40 patients without history of neoplasm, psychiatric disorders or infections of the central nervous system associated or not to HIV, with stable and effective antiretroviral therapy during at least 48 months. Use was made of the ASDE DRIVER TEST N-845 standardized by the Spanish traffic authorities, and for which data corresponding to the Spanish general population were obtained from the manufacturer of the test battery. The Student t-test was used to compare the different variables with the population standards, and the comparison of proportions Z-statistic was used to determine the proportion of subjects above the accepted limit of normality cutoff point. These analyses were replicated for the two sub-samples (with or without efavirenz therapy), with a 95% confidence level. The SPSS version 15 statistical package and Epidat 3.1 program were used. Results: The scores obtained in the HIV group were significantly poorer in the anticipation speed tests and in one of the multiple reactions test, though better results were obtained in the bimanual visual-motor coordination test. There were no differences in the percentages of patients with scores below the recommended limits. On comparing the treatment subgroups (efavirenz versus protease inhibitor), no differences were recorded in any of the study variables, and the differences with respect to the general population were the same as those described for the global group. Conclusions: Little differences were observed in driving skills in HIV well controlled HIV patients of minor clinical significance, and no differences were found in driving skills between the patients administered Efavirenz and those receiving protease inhibitor treatments.
