Prospective study reveals automated driving simulator metrics predict long-term driving outcomes in traumatic brain injury, indicating digital evaluations surpass standard road tests.

Key Points

To determine whether automated driving simulator metrics and traditional on-road driving tests predict long-term community driving performance in patients with traumatic brain injury.
Assessed 11 patients with moderate-to-severe traumatic brain injury and 16 healthy controls at baseline (time-1) using a 30-minute automated Simulator Performance Index (SPI), an observer-rated Driving Performance Inventory (DPI), and an on-road test.
Re-evaluated patient driving performance 10 months later (time-2) via family member ratings on the DPI over at least 3 hours of observation across a 4-week interval.
Baseline automated SPI measures (steering control, speed, accidents, and vigilance during a divided-attention task) significantly predicted 10-month real-world vehicle handling, speed control, judgment, and showed a trend towards predicting crashes.
Automated simulator metrics provided greater predictive sensitivity and accuracy for long-term driving performance than observer-rated simulator scores.
Baseline certified on-road driving evaluations showed no statistically significant relationship with real-world driving performance at the 10-month follow-up.
