What Researchers Did
Researchers conducted a systematic review of randomised controlled trials to evaluate the effectiveness of various treatments for chronic foot ulcers in people with diabetes.
What They Found
Out of 22,250 articles identified, 262 randomised controlled trials were reviewed across 10 intervention categories. The study found that the certainty of evidence for most wound healing interventions was low or very low. Moderate evidence was found for two interventions, while hyperbaric oxygen therapy (HBOT) and three other treatments showed low quality evidence.
What This Means for Canadian Patients
For Canadian patients with chronic diabetic foot ulcers, this review suggests that while some treatments show promise, there is generally a lack of strong evidence for many interventions. Patients considering hyperbaric oxygen therapy for diabetic foot ulcers should be aware that the current evidence supporting its effectiveness is considered low quality according to this review.
Canadian Relevance
This study covers diabetic foot ulcers, which is a Health Canada-recognised indication for hyperbaric oxygen therapy. No direct Canadian connection or authors were identified.
Study Limitations
The primary limitation identified by the researchers was the overall low quality and insufficient evidence from the underlying randomised controlled trials for most wound healing interventions.
