Revised Geneva Score Calculator for Pulmonary Embolism

The Revised Geneva Score relies on an additive point system where individual risk factors are assigned specific integer values based on their statistical correlation with pulmonary embolism. The final score (Result) is the direct sum of all evaluated variables: Result = Age + DVT + Surgery + Neo + LimbPain + BloodSputum + HR + Compression. Input parameters generally include age categories (e.g., 65 years or older), previous deep vein thrombosis (DVT) or PE, recent surgery or fractures, active malignant neoplasia, unilateral lower limb pain, hemoptysis (blood in sputum), heart rate thresholds (75-94 bpm or 95+ bpm), and localized tenderness on deep venous palpation of the lower limbs. The cumulative total places the patient into specific risk tiers, such as low, intermediate, or high probability, which directly dictate subsequent diagnostic testing like D-dimer assays or CT pulmonary angiography.

Consider a 68-year-old patient presenting to the emergency department with acute shortness of breath and a heart rate of 102 beats per minute. Further clinical evaluation reveals no prior history of DVT, no recent surgery within the past month, and no active cancer. However, the patient reports unilateral left calf pain and tenderness upon palpation, but no hemoptysis. Using the Revised Geneva criteria, we sum the points: Age over 65 adds 1 point; heart rate greater than 95 bpm adds 2 points; unilateral lower limb pain adds 3 points; and unilateral deep venous palpation tenderness adds 4 points. All other factors contribute 0 points. The total calculation is Result = 1 + 2 + 3 + 4 + 0 + 0 + 0 + 0 = 10 points. This places the patient in a high-probability category, prompting immediate diagnostic imaging.

Always verify baseline physiological measurements such as heart rate prior to entering data, as minor fluctuations can shift a patient into a higher scoring bracket. Use this calculator strictly as a pretest probability adjunct alongside clinical judgment, rather than a standalone diagnostic instrument. Ensure thorough patient history taking to accurately capture recent surgical interventions or malignancy diagnoses within the specified timeframes.
