‘Fit2Drive’ Transforms Assessing Older Drivers with Cognitive Decline
With the help of an evidence-based calculator called “Fit2Drive,” researchers have made it easy to administer and evaluate an in-office test to predict an older individual’s probability of passing an on-road driving test. Based upon brief, easily administered cognitive tests, Fit2Drive provides an objective estimation of the ability to drive for those with cognitive concerns. Results show that the Fit2Drive algorithm demonstrated a strong 91.5% predictive accuracy.
