What this is
Score the two best-validated pretest probability tools for pulmonary embolism side by side - the Wells PE criteria and the revised Geneva score. Both return a probability category (low, moderate, high) that drives the next diagnostic step (D-dimer if low, CT-PA if high, age-adjusted D-dimer in the gray zone). Sophie Well takes the shared clinical inputs once - heart rate, immobilization or recent surgery, prior DVT/PE, hemoptysis, active malignancy, clinical signs of DVT, alternative diagnosis less likely - and computes both scores so a clinician can see whether the two systems agree on the disposition.
When to use it
Use this when an ED or admitting workup raises concern for PE and you want a documented pretest probability before ordering D-dimer or CT-PA, when one of the two scores feels off and you want the other as a cross-check, or when an institution's protocol specifies a particular tool but the documenting provider is more familiar with the other. Pretest probability is the gatekeeper for whether a D-dimer rules out PE - it is meaningless after the imaging is already ordered - so the right time to compute it is before the diagnostic workup begins.
