Data Impact Challenge Question 6d

Question 6d: What portion of older adults (65+) has been prescribed antipsychotics to treat behavioural and psychological symptoms of dementia? (Relates to Choosing Wisely Canada Geriatrics recommendation #4)

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, four submissions were received in response to this question. The first submission was received within four weeks following the Challenge launch date. There were provincial and national datasets included.

The scope of assessments included inpatient acute, outpatient, long-term care and complex continuing care. The aggregate sample size for all submissions was approximately 2.3 million patients.

Guiding Specifications
