Severity-Stratified Healing Outcomes of Nurse-Managed Negative Pressure Wound Therapy in Diabetic Foot Ulcers: A Prospective Comparative Cohort Study.
Diabetic foot ulcers are a serious complication of diabetes that can lead to amputation if not treated effectively. Negative pressure wound therapy (NPWT) is a treatment that uses a vacuum device to draw fluid from the wound and promote healing. This study looked at whether NPWT managed by nurses could heal ulcers of different severities. They followed 120 patients with diabetic foot ulcers, comparing those who received nurse-managed NPWT to those who received standard wound care. The study found that patients with mild to moderate ulcers had significantly better healing rates with NPWT: 85% healed compared to 60% with standard care. However, for severe ulcers, the difference was not as clear, with 45% healing in the NPWT group versus 40% in the standard care group. These findings suggest that NPWT is most effective for less severe ulcers, but may still offer some benefit for severe ones. The study was limited by its small size and short follow-up, so more research is needed to confirm these results.
Key takeaways
- Nurse-managed NPWT healed 85% of mild-to-moderate diabetic foot ulcers, compared to 60% with standard care.
- For severe ulcers, healing rates were similar: 45% with NPWT and 40% with standard care.
- The study included 120 patients and followed them for 12 weeks, tracking complete wound healing.
- NPWT involves a vacuum dressing that removes excess fluid and stimulates blood flow to the wound.
- Patients with less severe ulcers may benefit most from this therapy, potentially avoiding amputation.
- Ask your doctor if NPWT is suitable for your ulcer and whether it can be managed by nurses.

Editor's note
Think of negative pressure wound therapy like a gentle vacuum that sucks out extra fluid and pulls fresh blood into the wound, bringing oxygen and nutrients that help it heal. For someone told their diabetic foot ulcer won't heal or that amputation is the only option, this study offers real hope: for mild to moderate ulcers, nurse-managed NPWT healed 85% of cases, much higher than standard care. Even for severe ulcers, it helped some patients. In China's specialist DFU centres, NPWT is routinely used, often by trained nurses, making it a standard option. As an international patient, you can access this therapy, and it might save your foot. It's not a miracle cure, but it's a powerful tool—especially when started early.
