Background: Despite several randomized trials, systematic reviews and meta-analyses that have demonstrated the effectiveness of antimicrobial (triclosan-coated or -impregnated) sutures (TCS), the clinical and economic impact of using these sutures compared with conventional non-antimicrobial-coated absorbable sutures (NCS) remains poorly documented.Methods: An independent systematic review and meta-analysis of all published evidence from January 2005 to September 2016 comparing TCS with NCS was conducted. Surgical-site infection (SSI) was the primary outcome. The results of the meta-analysis were used in a decision-tree deterministic and stochastic cost model, using the National Health Service (NHS England)-based cost of inpatient admissions for infections and differential costs of TCS versus NCS.Results: Thirty-four studies were included in the final assessment from an initial 163 identified citations; 20 of 34 studies were randomized, and 17 of 34 reported blinding of physicians and assessors. Using a random-effects model, the odds ratio for SSI in the TCS compared with NCS control groups was statistically significant (odds ratio 0⋅61, 95 per cent c.i. 0⋅52 to 0⋅73; P < 0⋅001). There was significant heterogeneity (I 2 = 49 per cent). Using random-effects event estimates of SSI for TCS and NCS for each individual wound type, the mean savings per surgical procedure from using antimicrobial sutures were significant: £91⋅25 (90 per cent c.i. 49⋅62 to 142⋅76) (€105⋅09 (57⋅15 to 164⋅41); exchange rate 15 November 2016) across all wound types.
Conclusion:The reviewed literature suggested that antimicrobial sutures may result in significant savings across various surgical wound types.
