Key Takeaway
Consider NPWT for diabetic wounds to potentially reduce hospital stay and complications, but evidence is limited.

This systematic review and meta-analysis of 21 studies evaluated negative pressure wound therapy (NPWT) versus standard care dressings (SCD) for diabetic wounds. The primary analysis showed that NPWT significantly reduced hospitalisation period by a mean of 7.8 days (95% CI: -14.2 to -1.4, p = 0.017) and significantly reduced complication rates (95% CI: -10.2 to -1.3, p = 0.01). Other outcomes such as healing duration, wound closure, local inflammation, oxidative stress, angiogenesis, and scarring were assessed but pooled effect sizes were not reported.

The authors note several limitations, including a paucity of studies, small cohort sizes, and scarce consistency in outcomes across trials. Adverse events, serious adverse events, and discontinuations were not reported. The review highlights the potential benefits of NPWT in diabetic wound management but cautions that clear conclusions are limited and further research is needed to fully understand NPWT's role.

Clinicians should interpret these findings cautiously given the methodological limitations. While NPWT appears to reduce hospital stay and complications, the evidence base is not robust enough to mandate practice change without considering individual patient factors and local resources.

This systematic review and meta-analysis looked at 21 studies involving patients with diabetic wounds. The researchers compared Negative Pressure Wound Therapy against standard care dressings to see how the treatments affected healing and recovery.

The analysis found that using Negative Pressure Wound Therapy significantly reduced the hospitalization period by an average of 7.8 days. It also showed a significant reduction in complication rates. The study looked at many other outcomes, including wound closure, local inflammation, and scarring, though specific results for these were not detailed in the main findings.

Despite these positive results, the study has important limitations. The researchers noted a scarcity of consistent outcomes and small cohorts in the included studies. Because of these gaps, the data cannot fully explain the role of this therapy or prove it works for every patient. Readers should understand that while the findings are promising, more consistent data is needed before this becomes a standard recommendation for everyone.

What this means for you:
Analysis of 21 studies suggests Negative Pressure Wound Therapy may shorten hospital stays for diabetic wounds, though data is limited.

Although Negative Pressure Wound Therapy (NPWT) has been increasingly used in wound care to improve impaired healing, there is little scientific evidence supporting its role and underlying biomolecular mechanisms. Aims of the present study are to provide a quantitative analysis of recent literature investigating NPWT in diabetic wound healing focusing on healing duration, wound closure, hospitalisation period and complications, and qualitative insight into studies analysing biomolecular mechanisms. The systematic review and meta-analysis were conducted following PRISMA guidelines (PROSPERO: CRD42024524813). 21 studies published in PubMed, Cochrane Library, EMBASE between 2019 and 2024 were included. Clinical studies indicated NPWT was superior to standard care dressings (SCD), promoting faster wound healing with significantly reduced hospitalisation times by 7.8 days (95% CI: -14.2 to -1.4, p = 0.017), and significantly reduced complications rates, particularly major and minor amputations (95% CI: -10.2 to -1.3, p = 0.01). Mechanistic in vitro and animal studies highlighted NPWT can reduce local inflammation, oxidative stress, support angiogenesis and improve scarring, essential components of normal healing. Although studies suggest NPWT is more effective than SCD for diabetic wound healing, the paucity of studies, small cohorts and scarce outcomes consistency make defining clear conclusions challenging. There is still more evidence required to fully understand NPWT's role in the complex diabetic wound healing.
