Data Impact Challenge Question 6f

Question 6f: For what portion of adults were screening blood tests conducted in any given year? (Relates to Choosing Wisely Canada Family Medicine recommendation #5)

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.


Through the Data Impact Challenge, five submissions were received in response to this question. The first submission was received within the first week following the Challenge launch date. The submissions were from Ontario, Alberta and Manitoba.

The population scopes ranged from individual primary care organizations to province-wide health care databases. All five submissions focused on outpatient blood testing.

The aggregate sample size for all submissions was approximately 12.1 million tests.
