Effectiveness of antibiotic prophylaxis in polytrauma patients: a systematic review and meta-analysis

Year: 2025

Type: review

Study designs: Systematic Review, Meta-Analysis

Abstract: Purpose The use of antibiotic prophylaxis in trauma patients, particularly to prevent ventilator-associated pneumonia (VAP), is debated due to rising antibiotic resistance. Therefore, this systematic review evaluated the safety and effectiveness of antibiotic prophylaxis compared to placebo or standard care on clinical outcomes in adult polytrauma patients. Methods We searched PubMed and the Cochrane Central Register of Controlled Trials to identify completed and ongoing studies from database inception to April 20, 2023. Eligible studies included systematic reviews and randomized controlled trials (RCTs) comparing antibiotic prophylaxis to placebo or standard care in adult polytrauma patients admitted to the intensive care unit (ICU). Results Of 1237 identified records, three RCTs involving 256 patients (n antibiotics = 176, n control = 165, mean age 37.4 years, 81.6% male) were included. Antibiotic prophylaxis showed little or no effect on all-cause mortality compared to placebo or standard care (RR 1.01, 95% CI 0.55–1.85; RD 2 more per 1000, 95% CI -79 to 150; 2 studies, 209 participants; I 2 = 0%; very low certainty of evidence). Conclusion The results indicate that antibiotic prophylaxis has no significant effect on mortality and clinical status compared with placebo or standard care in adult polytrauma patients but may reduce the risk of VAP. However, the evidence is outdated and of very low certainty, with insufficient data to draw definitive conclusions regarding efficacy. Therefore, high-quality, up-to-date research is urgently needed to support clinical decision-making, and current interpretations should be treated with caution.
