Abstract
BACKGROUND: To evaluate whether a single-use negative pressure wound therapy (sNPWT) device can reduce the incidence of surgical site infection (SSI) in at-risk patients with closed surgical incisions across a range of surgical specialties, compared with standard care. METHODS: PubMed, Embase, Cochrane Library and ClinicalTrials.gov were searched from the period January 2011 to April 2021. RESULTS: Out of 15,283 articles identified, 19 were included. A statistically significant improvement (p < 0.05) in the composite SSI (odds ratio [OR]: 0.36; 95 % confidence interval [CI]: 0.27-0.49), superficial SSI (OR: 0.30; 95 % CI: 0.17-0.53), and deep SSI (OR: 0.67; 95 % CI: 0.46-0.96) outcomes was observed with the sNPWT device compared with standard care in a pooled analysis of all surgical specialties. CONCLUSION: A -80 mmHg sNPWT device reduces the incidence of composite, superficial, and deep SSIs when compared with standard care across a heterogenous at-risk surgical population containing a variety of surgical specialties.
