Association between post-craniotomy Propionibacterium acnes infection and dural implants: a case-control study

There was a positive association between using dural implants and P. acnes infection. Infection may have been facilitated by inefficient use of skin disinfectant and environmental factors. Recommendations included ongoing surveillance, the use of chlorhexidine skin disinfectant, ensuring adequate air exchanges and appropriate use of doors in theatre to minimize air turbulence.
