Surgical Site Infections after Tissue Flaps Performed in Low- and Middle-Human Development Index Countries: A...

Surgical site infections (SSIs) affect the safety of surgical care and are particularly problematic and prevalent in low and middle Human Development Index Countries (LMHDICs).

We performed a systematic review of the existing literature on SSIs after tissue flap procedures in LMHDICs through the PubMed, Ovid, and Web of Science databases. Of the 405 abstracts identified, 79 were selected for full text review, and 30 studies met inclusion criteria for analysis.

In the pooled analysis, the SSI rate was 5.8 infections per 100 flap procedures (95% confidence interval [CI] 2%-10%, range: 0-40%). The most common indication for tissue flap was pilonidal sinus repair, which had a pooled SSI rate of 5.6 infections per 100 flap procedures (95% CI 2%-10%, range: 0-15%). No fatalities from an infection were noted. The reporting of infection epidemiology, prevention, and treatment was poor, with few studies reporting antibiotic agent use (37%), responsible pathogens (13%), infection comorbidities (13%), or time to infection (7%); none reported cost.

Our review highlights the need for more work to develop standardized hospital-based reporting for surgical outcomes and complications, as well as future studies by large, multi-national groups to establish baseline incidence rates for SSIs and best practice guidelines to monitor SSI rates.
