摘要：Background and Purpose: Aging is associated with cognitive impairment, which interferes with safe
driving ability. Cognitively-impaired drivers may present as confused and belligerent, creating challenges
in differentiating these drivers from intoxicated or metabolically-impaired drivers. The Driver Orientation
Screen for Cognitive Impairment (DOSCI) was developed to assist identification of disorientation and was
piloted in the Iowa Department of Transportation. This study examined the feasibility, acceptability, and
usefulness of the DOSCI at licensing agency offices, and to investigate the association between DOSCI
performance and driver licensing outcomes. Methods: A sample of 2,510 DOSCI screens from 2,399
individuals was assessed. Data included the acceptability of the DOSCI among staff and clients, time to
complete assessments, DOSCI outcomes, and final driver license status. Results: On a 5-point scale, mean
score was 4.76 (SD=0.67) for Ease of Administration, 4.67 (SD=0.80) for Acceptance by Client, and 3.81
(SD=1.57) for Useful in Assessment. Clients who failed the assessment had significantly higher odds of
not receiving a driver’s license than clients who passed (OR=2.556). Conclusion: The DOSCI was quick
to administer, well-accepted, and was associated with licensing outcome. The tool has potential to
contribute to traffic injury prevention by identifying potentially impaired drivers requiring closer
examination in a licensing agency setting.
