Duke Criteria for Endocarditis Calculator

Infective endocarditis diagnostic criteria

Calculate Duke Criteria

Major: Positive Blood Cultures (typical organism, ≥2 sets)Major: Echo Evidence (vegetation, abscess, dehiscence)Minor: Predisposing Condition (heart condition or IVDU)Minor: Fever > 38°CMinor: Vascular Phenomena (Janeway, emboli, ICH)Minor: Immunologic Phenomena (Osler, Roth, GN, RF+)Minor: Micro Evidence (BC not meeting major, serology)

Clinical use

Use this calculator for infective endocarditis diagnostic criteria in thecardiovascular workflow. It is decision support and should be interpreted with the patient context, local protocols, and clinician judgment.

Interpretation

Definite = 2 major, or 1 major + 3 minor, or 5 minor. Possible = 1 major + 1 minor, or 3 minor. Essential for IE diagnosis pathway.

Required inputs
