Project description

The number of older people or those with disabilities, who want to drive, is growing. Occupational Therapist Driver Assessors (OTDAs), with their combined health and performance expertise, are well equipped to conduct clinic-based and on-road driving assessments of older people and those with disabilities. However, there is a lack of OTDAs internationally. Recognising this, we undertook a project to develop a web-based decision-training aid to enhance novice Occupational Therapists’ (OTs) capacity to make optimal fitness-to-drive decisions. For this, we generated a set of driver scenarios, and asked a sample of experienced OTDAs to make decisions on the scenarios. We statistically modelled the experts’ decisions to obtain an optimal consensus judgement policy, and then used this policy to explain how driver information provided in referrals should be used when making fitness-to-drive decisions. The case scenarios and consensus policy were incorporated into a web-based decision-training aid. A randomised controlled trial (n=166) was conducted to test the effectiveness of the decision aid on novices’ decision making capacity. Trained novices were able to identify more not fit-to-drive cases as compared untrained novices.

The training aid developed has the potential to improve fitness-to-drive decision making skills and increase the occupational therapy workforce for fitness-to-drive assessments. These mean improved quality and effectiveness of service delivery, and improved road safety for users.
