Assessing Appropriateness of CT and MRI Referrals for Headache and Lumbar: A Canadian Perspective on Patient-Centered Referrals

BACKGROUND

Inappropriate diagnostic imaging is a burgeoning problem within the Canadian healthcare system and imposes considerable burdens to efficiency and timeliness of care. Low back pain and headaches affect an immense portion of the general population and have become exceedingly common complaints from patients seeking diagnostic imaging from primary care physicians.

METHODS

A total of 399 magnetic resonance imaging (MRI) and computed tomography (CT) requisitions for lumbar and head scans were reviewed and assessed for appropriateness in concordance with published Choosing Wisely guidelines for head and lumbar diagnostic imaging. Requisitions were classified as appropriate, inappropriate, or incomplete. Baseline data collection showed 51.6% appropriateness, 12.0% inappropriateness, and 36.3% incompleteness. New patient-centered referral forms containing evidence-based red flags by Choosing Wisely Canada were created for head and lumbar MRI and CT. The aim was to increase awareness and consideration of the guidelines during the referral process. The new referrals were distributed among 149 local family physicians in addition to information pamphlets summarizing the need to reduce unnecessary diagnostic imaging for head and lower back pain.

RESULTS AND CONCLUSION

After collection and review of 251 requisitions in the postintervention period, incomplete referrals dropped from 36.3% to 13.15%. Despite insignificant changes in appropriateness, it is promising that the intervention educated local physicians on the information required to complete the CT or MRI forms as further evidence is provided showing the efficacy of the patient-centered referrals. This study provides insight on the importance of appropriate diagnostic imaging and what methods can be used at the primary care level.

The Choosing Wisely Initiative: A critical analysis with a special focus on primary care

The Choosing Wisely initiative (CWI), a campaign led by the American Board of Internal Medicine (ABIM) Foundation, promotes doctor-patient communication and reducing waste in healthcare. At present, many of the top 5 lists from the Choosing Wisely Initiative appear to be primarily eminence-based and influenced by self-interest. The implementation of recommendations from these lists may mean taking a step backwards to the time before evidence-based medicine. On the other hand, despite all the challenges that the Choosing Wisely initiatives are currently facing, it is difficult to deny that they also hold great potential in terms of making healthcare systems more efficient and beneficial to patients. The aim of the ongoing work in Germany and Austria is to create conditions that are necessary if CW initiatives are to evolve into a model tool that will help introduce the principles of evidence-based medicine into daily practice.
