To assess whether targeted intraoperative hygiene measures could reduce surgical site contamination with Cutibacterium acnes in male patients undergoing cardiac surgery.
Approach:
Study Design: A multicenter, parallel-group, randomized clinical trial conducted at a university hospital and a university-affiliated teaching hospital in Munich, Germany, from October 28, 2024, to March 3, 2025.
Key Findings:
Cutibacterium acnes is now recognized as a relevant pathogen in prosthetic valve endocarditis.
The prevalence of C acnes in PVE cases is estimated to be between 3.8% and 8.0%.
Current disinfection protocols may not effectively eliminate C acnes from deep within hair follicles.
Interpretation:
The study aims to determine the effectiveness of enhanced intraoperative hygiene measures in reducing C acnes contamination during cardiac surgery.
Limitations:
The study was limited to male patients, which may affect the generalizability of the findings.
The trial's duration and sample size may limit the statistical power to detect differences.
Conclusion:
The study investigates the effectiveness of enhanced hygiene practices in reducing C acnes contamination during cardiac surgery.
