A Scoping Review of Foot Screening in Adults With Diabetes Mellitus Across Canada

Regular foot screening by a knowledgeable health-care provider is the cornerstone of ulcer and amputation prevention in people with diabetes. However, information on foot screening practices among Canadians with diabetes remains sparse. Therefore, we sought to synthesize available data on the frequency and approach to diabetic foot screening across Canada.

We conducted a scoping review by searching MEDLINE and Embase databases, alongside a grey literature search, for both English- and French-language reports. Data on patients' demographics, setting as well as the frequency of and approach to foot screening were abstracted. Title and abstract screening, full-text review and data abstraction were conducted in duplicate, with discrepancies resolved by a third reviewer.

The search yielded 21 reports including information on diabetic foot screening practices in Canada. In a consolidated study sample of 13,388 Canadians with diabetes, 7,277 (53%) reported receiving a foot examination by a health-care provider at least once in the past year. The majority of reports did not provide information on the demographics of patients being screened or details on the approach to foot screening. No report mentioned the use of a triage algorithm applied to the results of foot screening.

In this work, we identified the limited frequency and uncertain quality of diabetic foot screening across Canada. Further research should focus on better understanding disparities and barriers to regular diabetic foot screening.
