Clinical decision support for urinary tract infection

More clarity. Better UTI decisions.

Enter age, sex, and point-of-care urinalysis findings to estimate UTI probability with the current model.

Factors worth keeping in mind

These do not alter the model’s number. They are here so the clinical picture stays in view while you interpret it.

    Current model inputs

    Fast, native, and limited to the trained model.

    The calculator runs directly on the page using age, sex, and the twelve point-of-care urinalysis variables in the uploaded H2O model. It does not ask for symptoms, chief complaint, or clinical history.

    1. Enter the urinalysis. Tap each finding from the point-of-care dipstick and microscopy.
    2. See the probability instantly. The model’s estimate of urine culture positivity recalculates with every tap.
    3. Interpret with judgment. Risk bands and the balanced operating point sit alongside the number — the culture and your clinical assessment still decide.

    Model performance

    Evidence

    Operating points below come from the model’s held-out test set. The model was built on 22,000 paired point-of-care urinalysis and urine culture results.

    4.7451%

    High-sensitivity point — about 95% sensitivity

    13.7033%

    Balanced point — sensitivity 0.7999, specificity 0.7992

    42.3409%

    High-specificity point — PPV 0.7121
