Is this trial a fit for you?

Likely a good fit

Adults (18+) with definite or possible infective endocarditis per 2023 Duke-ISHC criteria, who have given informed consent.

Probably not a fit

Patients with very high risk of death within 14 days or those who have already started antibiotic therapy before enrollment may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, open-label trial tests whether an etiological diagnostic algorithm that includes culture-based methods and molecular tests can increase the use of etiotropic antibiotics within 14 days of diagnosing infective endocarditis. Results are shared with clinicians in the intervention group to guide treatment, while the control group remains blinded to molecular results. The study enrolls adults with definite or possible infective endocarditis and compares the antibiotic decision-making between groups.

Why it matters

Potential benefit: If successful, patients may receive more targeted antibiotics sooner, potentially improving outcomes.

How similar studies have gone: Previous studies using integrated culture and molecular methods have shown promise in guiding therapy, but this trial adds a blinded-control design to assess impact.
