Infective Endocarditis Duke Criteria

Diagnoses infective endocarditis using major criteria (≥2 positive blood cultures with typical organisms, new valvular regurgitation or echo vegetation) and minor criteria (predisposing heart condition, IV drug use, fever >38°C, vascular phenomena, immunologic phenomena). Definite: 2 major OR 1 major+3 minor OR 5 minor.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Diagnoses infective endocarditis using major criteria (≥2 positive blood cultures with typical organisms, new valvular regurgitation or echo vegetation) and minor criteria (predisposing heart condition, IV drug use, fever >38°C, vascular phenomena, immunologic phenomena). Definite: 2 major OR 1 major+3 minor OR 5 minor

Each component has a specific meaning:

  • Major criteria (≥2 positive blood cultures — The major criteria (≥2 positive blood cultures recorded for the scenario being assessed.

Note: Interpret the duke ie criteria result against the thresholds and context described above.

How to Use

Enter the major criteria (≥2 positive blood cultures for the scenario you are assessing. Diagnoses infective endocarditis using major criteria (≥2 positive blood cultures with typical organisms, new valvular regurgitation or echo vegetation) and minor criteria (predisposing heart condition, IV drug use, fever >38°C, vascular phenomena, immunologic phenomena). Definite: 2 major OR 1 major+3 minor OR 5 minor. Use the duke ie criteria result to inform your calculation.
