Lower limb amputation rates among Medicare beneficiaries with diabetic foot ulcers managed with and without native collagen matrix plus PHMB antimicrobial.
A recent study published in the Journal of Wound Care examined whether a specific wound dressing—native collagen matrix with PHMB antimicrobial—could help reduce the risk of lower limb amputation in people with diabetic foot ulcers. Researchers analyzed Medicare data from 2015 to 2023, comparing over 10,000 patients who used this dressing with a matched group who did not. Despite having more severe ulcers initially, patients in the dressing group had a significantly lower amputation rate within six months: 2.7% versus 4.3% in the comparison group. This suggests that using this advanced dressing may help preserve limbs, even in high-risk patients. However, because the study was observational, it cannot prove cause and effect. Additionally, it focused only on Medicare beneficiaries in the US, so results may not apply to other populations. Nonetheless, these findings are encouraging and highlight the potential benefits of advanced wound care products in DFU management.
Key takeaways
- A study of over 10,000 Medicare beneficiaries found that using a native collagen matrix with PHMB antimicrobial was associated with a lower six-month amputation rate (2.7%) compared to not using it (4.3%).
- Patients who used the dressing had more severe ulcers initially, yet still had fewer amputations, suggesting it may be beneficial for high-risk cases.
- This is one of the largest real-world analyses on this type of dressing, providing strong evidence for its potential role in DFU care.
- If you have a diabetic foot ulcer, ask your doctor if this advanced dressing might be appropriate for your wound.
- The dressing is not a cure, but it may be a valuable addition to standard care to help save limbs.
- Availability of collagen-based dressings may vary by region and clinic, so discuss access with your healthcare team.

Editor's note
For patients with diabetic foot ulcers in China, this study offers hope that advanced dressings like collagen matrix with antimicrobial properties can be a valuable part of treatment. While the product may not be available in every hospital, it is worth discussing with your doctor, especially if you are treated at a specialized DFU center. This research underscores the importance of using evidence-based wound care products to reduce amputation risk. When talking to your doctor, ask about the availability of such dressings and whether they could be integrated into your care plan. Remember, this dressing is an adjunct to standard care, not a replacement, so continue following your doctor's advice on offloading, infection control, and blood sugar management.
