Data Impact Challenge Question 6c

Question 6c: What portion of older adults (65+) has been prescribed benzodiazepine, or other sedative hypnotics, for insomnia, agitation or delirium? (Relates to Choosing Wisely Canada Geriatrics recommendation #2)

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, three submissions were received in response to this question. The first submission was received within three weeks following the Challenge launch date. Submissions were received with Ontario and national scopes. There was variation among settings with one submission collected data from long-term care (LTC), complex continuing care (CCC), and long-stay home care patients, while the others focused on primary care.

The aggregate sample size for all submissions was approximately 375,000 exams.
