In partnership with several national organizations, referring clinicians, radiologists, and patient and family advisors from across Canada, the association is redoing its referral guidelines using a new methodology for guideline development, and these guideline recommendations will be suited for integration into clinical decision support systems.Methods: Expert panels of radiologists, referring clinicians and a patient advisor will work with epidemiologists at the CAR to create guidelines across 13 clinical sections. The expert panel for each section will first create a comprehensive list of clinical and diagnostic scenarios to include in the guidelines. Canadian Association of Radiologists epidemiologists will then conduct a systematic rapid scoping review to identify systematically produced guidelines from other guideline groups. The corresponding expert panel will develop diagnostic imaging recommendations for each clinical and diagnostic scenario using the recommendations identified from the scoping review and contextualize them to the Canadian health care systems. The expert panels will accomplish this using an adapted Grading of Recommendations Assessment, Development and Evaluation framework, which reflects the benefits and harms, values and preferences, equity, accessibility, resources and cost.Interpretation: Freely available, up-to-date, comprehensive Canadian-specific diagnostic imaging referral guidelines are needed. A transparent and structured guideline-development approach will aid the CAR and its partners in producing guidelines across its 13 sections.
