Predicting Fitness to Drive for Medically At-Risk Drivers Using Touchscreen DriveSafe DriveAware

This article explores the use of the touchscreen DriveSafe DriveAware (DSDA) screening tool to predict fitness to drive in medically at-risk drivers, including those with cognitive impairments. The study took place in 10 community- and hospital-based driver assessment clinics in Australia and New Zealand and included older and cognitively impaired drivers (n = 134) aged 18-91 years (mean age = 68 years). The study was undertaken to validate the data gathered with the touchscreen version of the DSDA tool by comparing its results with a standardized on-road test of driving ability (Performance Analysis of Driving Ability, Patomella, et al, 2010). The DSDA scores drivers into three categories: likely to pass an on-road assessment, likely to fail an on-road assessment, and further testing required. The authors found that specificity of the touchscreen DSDA was 86%, and sensitivity was 91%; positive predictive value was 83%, negative predictive value was 92%, and overall accuracy of classification was 88%. They stress that the touchscreen DSDA has three particular advantages to other predictive tests: it places only 11% of participants in the further testing category, it only takes about 10 minutes to complete, and participants can see how the test conditions relate to real-world driving, thus increasing acceptance of the results. The authors conclude that the touchscreen tool is useful and valid for predicting which participants require on-road testing of their fitness to drive.
