Study protocol of the safe driving program for the prevention of car accidents: A randomized controlled trial protocol.

Aim: Driving cessation is strongly associated with adverse health outcomes in older adults. Although numerous studies have focused on driving skill interventions for safe driving, the effects of interventions on car accidents remain unclear. We designed a randomized controlled trial to examine the effects of driving skill training on the prevention of car accidents among community‐dwelling older adults using on‐road training. Methods: A total of 1408 community‐dwelling older drivers aged ≥65 years participated in the randomized controlled trial with blinded endpoint assessment. Participants randomized to the intervention group (n = 697) underwent four sessions, with 200 min re‐training focused on the problem of driving in the older people. Controls (n = 697) received one classroom education session. On‐road driving performance was assessed by certified driving school instructors in a driving school. The primary endpoint is an incident car accident, which will be detected based on the Japanese national car accident report data, after 24 months. Discussion: This study has the potential to provide the first evidence of the effectiveness of on‐road driving skill training regarding the prevention of car accidents. If our trial results show a lower number of car accidents due to driving skill training, this kind of intervention will provide an effective method for maintaining safe driving. These results will be disseminated to the appropriate national transportation agencies to improve or modify safe driving policies and possibly extend the validity of driver's licenses for older adults.
