A Patient-focused Information Design Intervention to Support the Minor Traumatic Brain Injuries (mTBI) Choosing Wisely Canada Recommendation

摘要

Introduction The first Choosing Wisely Canada (CWC) recommendation for Emergency Medicine states: “Don’t order CT head scans in adults and children who have suffered minor head injuries (unless positive for a validated head injury clinical decision rule)”. In order to provide patients with information on the risks and benefits of computed tomography (CT) scans in minor traumatic brain injuries (mTBI) and to encourage discussions between patients and their doctor, we designed a patient-focused mTBI infographic for the emergency department (ED). Methods Stakeholders worked with content experts to co-design the infographic, which was posted in two emergency department (ED) waiting rooms. A survey was administered to evaluate whether the infographic influenced patient beliefs about the risks and benefits of CT scans?and to gauge patient willingness to have a discussion with their doctor about the necessity of a scan. Results One hundred fifteen patients completed the survey.?Prior to participating, 38% of patients thought a CT after an mTBI was always a good idea and 60% thought it was sometimes a good idea. After viewing the poster, 87% of respondents stated they better understood when a CT scan may be appropriate, 93% felt they better understood the risks of CT scans, and 76% understood that their doctor can often rule out serious illness without a CT scan. Only 19% of patients still felt that a CT was always necessary after an mTBI. Conclusions The mTBI infographic changed patient perceptions regarding the need for CT scans and increased awareness of the indications and risks of CT scans. This study demonstrates that targeted patient education materials can help support CWC recommendations.
