Abstract

Objective

We conducted this meta-analysis to explore the risk factors and incidence of deep surgical site infections (DSSIs) after orthopaedic trauma surgery.

Methods

A systematic search was conducted across various databases, including MEDLINE, Embase, Cochrane Library, and Web of Science, for studies examining risk factors associated with DSSIs after bone trauma procedures. The search concluded on September 1, 2024. Data analysis was performed using Stata 15.0.

Results

Among 2,722 publications screened, 16 studies that met the eligibility criteria were included in the analysis, involving a total of 22,318 patients, of whom 894 experienced DSSIs. The meta-analysis revealed a combined incidence of deep infections after orthopedic trauma surgery at [ES = 6.7%, 95% CI (5.1%–8.2%)]. Risk factors identified included male gender [OR = 1.99, 95% CI (1.39, 2.86), p < 0.0001], current smoking status [OR = 2.60, 95% CI (1.85, 3.65), p < 0.0001], open injuries [OR = 3.17, 95% CI (1.72, 5.85), p < 0.0001], a BMI greater than 26.0 kg/m2 [OR = 1.95, 95% CI (1.24, 3.07), p = 0.004], wound class ≥ 2 [OR = 2.40, 95% CI (1.56, 3.70), p < 0.0001], and a surgery duration of 60 min or more [OR = 2.41, 95% CI (1.63, 3.55), p < 0.0001]. These factors significantly contribute to the risk of developing DSSIs post-surgery. However, age did not exhibit a significant difference.

Conclusion

This study identifies key risk factors for DSSI following orthopedic trauma surgery, addressing a gap in the existing literature and offering some insights for clinical decision-making. To mitigate the risk of DSSI, clinical practice should encourage patients to lose weight and quit smoking prior to surgery, optimize surgical procedures, and improve wound management strategies. Future research should aim to standardize follow-up durations and further refine the classification of risk factors, in order to validate and expand on the conclusions of this study.
