What Researchers Did
Researchers retrospectively analyzed cost and mortality data for 159 diabetic patients with Wagner Grade 3 or 4 foot ulcers, comparing an evidence-based limb salvage protocol with adjunctive hyperbaric oxygen therapy to primary lower extremity amputation.
What They Found
The limb salvage protocol with hyperbaric oxygen therapy cost an average of USD $33,100, with 91.7% of patients having intact lower extremities at one year and a 35.4% mortality rate. In contrast, primary lower extremity amputation cost USD $66,300 to $73,000, with a 47.2% mortality rate.
What This Means for Canadian Patients
Canadian patients with severe diabetic foot ulcers may benefit from aggressive limb salvage programs including hyperbaric oxygen therapy, potentially leading to better limb preservation and lower healthcare costs. This approach could offer a more favorable outcome compared to immediate amputation.
Canadian Relevance
This study does not have a direct Canadian connection as it was conducted outside of Canada. However, its findings on cost-effectiveness and limb salvage for diabetic foot ulcers could inform Canadian clinical practice.
Study Limitations
As a retrospective study, it is subject to potential selection bias and unmeasured confounding factors.
