Abstract

Introduction: Our aim was to evaluate the variability in the processing of osteoarticular samples for microbiological diagnosis between different national centers.

Methods: An online survey with 13 questions was designed and it was sent through SEIMC to the Microbiology Departments of the different centers.

Results: We obtained 72 answers. In more than half of the tertiary-care centers, at least 5 samples are received. Approximately half of the centers vortex bones/implant samples. Sonication is used mostly in tertiary-care centers. Cultures for aerobic and anaerobic bacteria are performed during 6-10 days of incubation but with differences in liquid culture media. Molecular diagnosis is performed in less than 50% of the centers. Universal PCR (16S rRNA) is the most widely used technique.

Conclusion: We found heterogeneity especially in the use of sonication, liquid culture media or molecular diagnosis, probably in direct relation to the resources and capacities of each center.
