Closed Incision Negative Pressure Therapy versus Standard of Care in Reduction of Surgical Site Complications: A Systematic Review and Meta-analysis.

Unlabelled: Closed incision negative pressure therapy (ciNPT) has been utilized to help manage closed incisions across many surgical specialties. This systematic review and meta-analysis evaluated the effect of ciNPT on postsurgical and health economic outcomes.

Methods: A systematic literature search using PubMed, EMBASE, and QUOSA was performed for publications written in English, comparing ciNPT to standard-of-care dressings between January 2005 and August 2021. Study participant characteristics, surgical procedure, dressings used, treatment duration, postsurgical outcomes, and follow-up data were extracted. Meta-analyses were performed using random-effects models. Risk ratios summarized dichotomous outcomes. Difference in means or standardized difference in means was used to assess continuous variables reported on the same scale or outcomes reported on different scales/measurement instruments.

Results: The literature search identified 84 studies for analysis. Significant reductions in surgical site complication (SSC), surgical site infection (SSI), superficial SSI, deep SSI, seroma, dehiscence, skin necrosis, and prolonged incisional drainage were associated with ciNPT use ( < 0.05). Reduced readmissions and reoperations were significant in favor of ciNPT ( < 0.05). Patients receiving ciNPT had a 0.9-day shorter hospital stay ( < 0.0001). Differences in postoperative pain scores and reported amounts of opioid usage were significant in favor of ciNPT use ( < 0.05). Scar evaluations demonstrated improved scarring in favor of ciNPT ( < 0.05).

Discussion: For these meta-analyses, ciNPT use was associated with statistically significant reduction in SSCs, SSIs, seroma, dehiscence, and skin necrosis incidence. Reduced readmissions, reoperation, length of hospital stay, decreased pain scores and opioid use, and improved scarring were also observed in ciNPT patients.
