The overuse of diagnostic imaging (DI) services, which is estimated to be 30% in Canada, can expose patients to unnecessary radiation, and strain human and financial resources. This study explored the DI ordering practices of physicians in Canada through semi-structured interviews to gain a deeper understanding of the factors contributing to the overuse of DI services. The majority of participants (n=11; 91%) described feeling pressured by patients to order DI services in circumstances that were unwarranted. The results are followed by a discussion about ways technology (such as a decision support system) could aid in facilitating a dialogue between physicians and patients about when and when not to order DI.
