Data Impact Challenge Question 6b

Question 6b: For what portion of adults is a dual energy X-ray absorptiometry (DEXA) scan repeated more often than every 2 years? (Relates to Choosing Wisely Canada Rheumatology recommendation #3)

Rationale
Choosing Wisely Canada is a campaign to help physicians and patients engage in conversations about unnecessary tests, treatments and procedures. Canadian national specialty societies participating in the campaign, representing a broad spectrum of physicians, were asked to develop lists of “Five Things Physicians and Patients Should Question.” These lists identify tests, treatments or procedures commonly used in each specialty, which are not supported by evidence, and/or could expose patients to unnecessary harm. Increasing understanding of the frequency with which care does or does not follow these recommendations could support targeted improvement and potentially could impact policy interventions.

Results

Through the Data Impact Challenge, two submissions were received in response to this question. The first submission was received within the first week following the Challenge launch date. Submissions came from Alberta and an Ontario hospital. In both submissions, the scope included inpatient and outpatient scans. The aggregate sample size for all submissions was approximately 58,000 scans.
