Brief Summary

Based on the literature on dementia and driving, and on knowledge tools available to date including one from our current work, a Driving in Mild Dementia Decision Tool (DMD-DT) will be adapted and tailored to guide physicians in their decisions to report a driver with mild dementia to the provincial licensing agency. The DMD-DT intervention will include a) an algorithm-based computerized clinical decision support system (CCDSS) for facilitating driving assessment and physicians' reporting to provincial transportation authorities, b) an individualized educational package for patients and caregivers about dementia and driving and driving cessation, and c) a modified reporting form to provincial driving regulatory authorities. Months 1 to 6: The DMD-DT will be tailored and adapted to practice with the input of the co-investigators and knowledge-users who represent the perspectives of physicians, patients and their caregivers, as well as transportation authorities. Pilot testing will be done, and input from focus groups of knowledge-users will refine the intervention. Physicians will be recruited to participate in a clinical trial of the DMD-DT. Months 7-18: A parallel-group cluster randomized controlled trial (RCT) will be conducted to compare the effects of the DMD-DT to a legislation reminder on recommendations for reporting to the licensing agency. The effects of the DMD-DT on the doctor-patient relationship will be further explored in focus groups and interviews with physicians. Months 19-24: The knowledge obtained from the study will be used to generalize and sustain use of the intervention beyond Ontario, Canada, and to disseminate the information to knowledge-users. The primary outcome measure is the filing of a report to the Ministry of Transportation of Ontario, indicating that the physician has a concern about the patient's health condition (i.e. mild dementia). The primary outcome of the study is the difference in reporting between the DMD-DT and control arms. Since the current reporting rate is low, approximately 13%, from a public health point of view, the primary outcome expected is that physicians in the DMD-DT group will report more patients with mild dementia than those in the control group.

Outcome Measures

Primary Outcomes (1)

  • Number of patients reported to the Ontario Ministry of Transportation

    The primary outcome of this study is the number of patients reported to the Ontario Ministry of Transportation by study participants. A "report" indicates that the participant believes his/her patient may be unsafe to continue driving due to mild cognitive impairment or mild dementia. The difference in the number of reports filed between the intervention and control group participants will be assessed.

    When participants have completed 500 patient assessments (expected to take approximately 12 months)

Secondary Outcomes (3)

  • The number of "false positives", i.e. number of patients reported to the Ontario Ministry of Transportation as potentially being unsafe drivers who are deemed by expert consensus to be safe drivers.

    When participants have completed 500 patient assessments (expected to take approximately 12 months)

  • Number of recommendations given for specialized on-road testing

    When participants have completed 500 patient assessments (expected to take approximately 12 months)

  • Quality of Doctor-Patient Relationship

    When participants have completed 500 patient assessments (expected to take approximately 12 months)

Study Arms (2)

Intervention

EXPERIMENTAL

Participants in this arm will assess patients using the Driving in Mild Dementia Decision Tool.

Other: Driving in Mild Dementia Decision Tool

Control

NO INTERVENTION

Participants in this arm will assess patients using their usual care strategies.
