Background:
Negative pressure wound therapy (NPWT) is a technology-based modality therapy in the treatment of diabetic foot ulcers used by nursing. However, there are variations in its effectiveness among patients, which requires further research to better understand. This systematic study investigated the effect of NPWT on the healing of diabetic foot ulcer (DFU).
Material and Methods:
The databases consulted were CINAHL, ProQuest, PubMed, ScienceDirect, and Wiley, with a date range restriction from September 2003 to July 2022. The inclusion criteria were full-text articles with a randomized controlled trial design and English publication. They were using comprehensive meta-analysis (CMA) version 3.3.070 software to conduct a meta-analysis.
Results:
There were 1.375 participants in 14 trials, and residual heterogeneity analysis indicated wound healing I-squared (I
2
) of 97.70%, microcirculation I
2
of 90.20%, and infection I
2
of 98.50% (I
2
> 50%), indicating high heterogeneity. The random effect model value showed a significant positive effect on wound healing with
Conclusions:
The findings of this study indicate that NPWT administered by nurses improves wound healing in DFU patients. Regarding infection control, this study did not produce statistically significant results.
