For example, for SABA over-use we used the Canadian guidelines that define over-use as more than 250 doses in 90 days as prior research had shown that overuse of this magnitude is associated with an increased risk of asthma mortality [ 25- 27].
The Canadian guidelines use a similar approach, stating that most adults with diabetes should be considered at high risk for vascular disease.
The Institute of Medicine criteria [ 5] were used in the first national surveillance study in 2001 [ 30], the Canadian guidelines [ 17] were used in the first national prevalence study in 2009 [ 31], and the University of Washington (UW) 4-Digit Diagnostic Code [ 8] has been proposed for national use by authors examining the issues of diagnostic capacity and surveillance [ 27, 28].
Consistent with the Canadian guidelines, we do not recommend use of the UW diagnostic category of neurobehavioural disorder-alcohol exposed at this time, which requires evidence of moderate as opposed to severe CNS dysfunction.
Uncertainty was most notable for the Australian diagnostic criteria for ND-AE, where consensus was to use diagnostic criteria comparable with the UW guidelines for SE-AE and the Canadian guidelines for ARND in the requirement for evidence of severe CNS dysfunction, which is a more conservative approach than recommended in other guidelines [ 4, 5].
The Canadian guidelines for the diagnosis of FASD 42 will be used to assign specific diagnoses along the FASD spectrum based on comprehensive interdisciplinary clinical assessment.
Moreover, this cross-sectional study using secondary data does not provide information to identify if the lipid test was requested according to the Canadian guidelines or other factors including patient request or a clinical suspicion by the family physician.
For instance, in the session on chronic obstructive pulmonary disease we pointed out that some recommendations in the Canadian guidelines[ 13] are based on studies that show statistical significance but not clinical significance based on the scales used for outcomes.
Some Canadian journalists also disagree with the Canadian guidelines.
Mammography is recognized as important in the Canadian guidelines, with mammograms recommended annually [ 2], although the Canadian guidelines do concede that there is little high level evidence to support this practice.
