cause serious harm, including premature death. Use of these
drugs should be limited to cases where non-pharmacologic
measures have failed and patients pose an imminent threat
to themselves or others. Identifying and addressing causes
of behaviour change can make drug treatment unnecessary.

Avoid using medications known to cause
hypoglycemia to achieve hemoglobin A1c
<7.5% in many adults age 65 and older; moderate control is generally better.
There is no evidence that using medications to achieve intense glycemic control in older adults with type 2 diabetes
is beneficial (A1c under 7.0%). Among non-older adults, except for long-term reductions in myocardial infarction and
mortality with metformin, using medications to achieve
glycated haemoglobin levels less than 6 % is associated
with harms, including higher mortality rates. Intense control has been consistently shown to produce higher rates
of hypoglycemia in older adults. Given the long timeframe
(approximately 8 years) to achieve theorized benefits of intense control, glycemic targets should reflect patient goals,
health status, and life expectancy. Reasonable glycemic targets would be 7.0 – 7.5% in healthy older adults with long
life expectancy, 7.5 – 8.0% in those with moderate comorbidity and a life expectancy < 10 years, and 8.0 – 8.5% in
those with multiple morbidities and shorter life expectancy.
How the list was created
The Canadian Geriatrics Society (CGS) established its Choosing Wisely Canada Top 5 recommendations by first establishing a small group of its Council members and Committee chairs to evaluate the American Geriatrics Society (AGS)
Choosing Wisely® list. Feeling confident that the AGS recommendations reflected geriatric care in Canada, the list
was presented to the CGS executive. After initial review by
the CGS executive, each topic was reviewed in detail by selected Canadian geriatricians and other specialists with the
relevant research and clinical expertise. This process was undertaken to ensure the recommendations and background
information for each topic were valid and relevant for Canadian patients and our health care system. Ultimately, all five
items were adopted with permission from the Five Things

Don’t order ANA as a screening test in patients without specific signs or symptoms
of systemic lupus erythematosus (SLE) or another connective tissue disease (CTD).
ANA testing should not be used to screen subjects without
specific symptoms (e.g., photosensitivity, malar rash, symmetrical polyarthritis, etc.) or without a clinical evaluation
that may lead to a presumptive diagnosis of SLE or other
CTD, since ANA reactivity is present in many non-rheum ]X
