Decolonization of Patients Carrying S. Aureus Before Cardiac Surgery: Study of the Risk Factors Associated With Failure

France215 participantsStarted 2019-02-12

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
