Diabetic Foot Ulcers

Summary

Wagner grade III+ diabetic lower-extremity wounds that fail 30 days of standard care qualify for covered HBOT.

Typical protocol

2.0–2.4 ATA × 90 min, Daily, 5×/week, 30–40 sessions · UHMS / Medicare NCD 20.29

The evidence (4)

1. [1] Hyperbaric oxygen therapy for chronic wounds (Cochrane systematic review)

   MIXED

   Kranke P, Bennett MH, Martyn-St James M, et al. · Cochrane Database of Systematic Reviews · 2015 · PMID 26106870

   Pooling 12 trials, the review found HBOT improved the chance of diabetic foot ulcers healing in the short term (around 6 weeks), though longer-term and amputation benefits were less certain and trial quality varied.

   Quality: Gold-standard systematic review; flags heterogeneity and modest trial quality.

2. [2] Hyperbaric oxygen: its mechanisms and efficacy

   POSITIVE

   Thom SR · Plastic and Reconstructive Surgery · 2011 · PMID 21200283

   Widely cited review of HBOT mechanisms: raised dissolved oxygen, stem/progenitor cell mobilization, angiogenesis, and effects on inflammation and reperfusion injury.

   Quality: Standard mechanistic reference for the field.

3. [3] Hyperbaric oxygen therapy facilitates healing of chronic foot ulcers in patients with diabetes (HODFU study)

   POSITIVE

   Löndahl M, Katzman P, Nilsson A, Hammarlund C · Diabetes Care · 2010 · n=94 · PMID 20427685

   In this randomized, double-blind, placebo-controlled trial, adding HBOT to standard wound care significantly improved complete healing of chronic diabetic foot ulcers at one year versus placebo (hyperbaric air).

   Quality: Double-blind RCT with sham control — one of the strongest single trials in the field.

4. [4] Adjunctive systemic hyperbaric oxygen therapy in treatment of severe prevalently ischemic diabetic foot ulcer

   POSITIVE

   Faglia E, Favales F, Aldeghi A, et al. · Diabetes Care · 1996 · n=70 · PMID 8941460

   Randomized trial in which adjunctive HBOT was associated with a significantly lower rate of major amputation in patients with severe ischemic diabetic foot ulcers.

   Quality: Early randomized evidence for limb salvage; unblinded.
