Summary

Staphylococcus aureus nasal carriage is a well-known risk factor for S. aureus surgical site infections (SSI). According to a recent study demonstrating 60% reduction risk of SSI due this bacterium after patients' screening and decolonization, recent French and WHO guidelines recommend in cardiac surgery the decolonization of nasal S. aureus carriers before surgery. In practice the decolonization procedures are not well-defined according notably to the duration and time of delivery before surgery and doses of topical antimicrobial drugs. The aim of the proposed study is to investigate the factors associated with failures of S. aureus decolonization: carriage state, compliance with treatment, S. aureus capacity of internalization in nasal epithelial cells, resistance to antimicrobial drugs used. This study will allow (i) to measure the frequency of patients with residual S. aureus carriage just before surgery, whatever they have been decolonized or not, (ii) to characterize the S. aureus nasal carriage state of patients before surgery, and (iii) to investigate the adding value of mupirocin dosage in the nose and urines of decolonized patients as a marker of compliance and efficacy of the decolonization process.

Conditions

  • Staphylococcus Aureus

Interventions

PROCEDURE

decolonization

current practice : V1 : consultation to the service : nasal sample for all 5 days before surgery : order sent with decolonization procedure : nasal mupirocin, shower and mouthwash V2 : admission to the service : nasal sample for all and urine sample for decolonized patients V3 : nasal sample for all

OTHER

compliance questionnaire

We asked if the patient has done the whole decolonization procedure
