Data Impact Challenge Question 6h

Question 6h: How frequently do physicians order Anti-Nuclear Antibody (ANA) as a screening test, and what level of variation exists across physicians? (Relates to Choosing Wisely Canada Rheumatology recommendation #1)

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, one submission was received in response to this question. The submission was received within nine weeks following the Challenge launch date. The submission collected data from an inpatient setting at an Ontario hospital with a sample size of approximately 1.1 million tests.

Guiding Specifications

Sample: Minimum sample size of 10,000 discharges.
Timeframe: Analysis should include at least six months of data.
