Efficacy of Honey Dressings in Treating Diabetic Foot Ulcers: A Meta-Analysis
Overview
This systematic review and meta-analysis of 16 randomized controlled trials involving 1423 patients found that honey dressings significantly improve complete healing rates and reduce time to healing in diabetic foot ulcers compared to conventional dressings. The quality of evidence was moderate for healing rates and low for time to healing.
Background
Diabetic foot ulcers (DFUs) are a common and serious complication of diabetes, leading to increased risk of infection, amputation, and mortality. Effective wound dressings are crucial for managing DFUs, requiring properties that promote hemostasis, infection control, and tissue repair. Medical-grade honey has demonstrated broad-spectrum antibacterial effects and facilitates wound healing, but prior evidence has been limited in quantity and quality. This meta-analysis aims to provide a comprehensive evaluation of honey dressings' efficacy in DFU treatment.

Key Findings
Honey dressings significantly increased the complete healing rate of diabetic foot ulcers (OR 2.28, 95% CI 1.76 to 2.95).
Use of honey dressings reduced the time to complete healing by an average of 4.38 days compared to conventional dressings (95% CI -8.06 to -0.71).
The meta-analysis included 16 RCTs with sample sizes ranging from 23 to 348 participants and follow-up durations between 4 and 24 weeks.
The overall quality of evidence was rated as moderate for healing rates and low for time to healing according to the GRADE system.
Honey dressings demonstrated safety and were associated with improved wound healing outcomes compared to standard dressings such as saline gauze, povidone-iodine, hydrocolloid, alginate, or foam dressings.
Clinical Implications
Clinicians should consider medical-grade honey dressings as a safe and effective option for managing diabetic foot ulcers to enhance healing rates and accelerate wound closure. Given the moderate quality of evidence supporting improved healing rates, honey dressings may be integrated into standard wound care protocols to potentially reduce complications and improve patient outcomes.
Conclusion
Honey dressings represent a superior alternative to conventional dressings in the treatment of diabetic foot ulcers, offering significant benefits in healing efficacy and speed. Further high-quality studies are warranted to strengthen evidence on time to healing.
