The Revised Geneva Score estimates how likely a patient is to have a pulmonary embolism before any diagnostic test is run, using eight clinical findings that can all be measured or observed directly. Emergency physicians use it to decide whether a negative D-dimer is enough to rule out PE, or whether imaging is needed regardless of the D-dimer result.
Why 'fully objective' matters
The Revised Geneva Score was designed specifically to remove the one subjective item that appears in the competing Wells score — "PE is the most likely diagnosis," a clinician gestalt judgment that varies between observers. Every Revised Geneva item is instead a measurable finding: an age threshold, a documented history, a heart rate reading, a physical exam finding. This makes the score more reproducible when different clinicians assess the same patient, which was the explicit goal of Le Gal and colleagues' 2006 derivation and validation study published in the Annals of Internal Medicine.
How the eight criteria are weighted
Seven criteria are simple present/absent checks worth fixed points: age over 65 (+1), previous DVT or PE (+3), surgery or lower-limb fracture within the past month (+2), active malignancy (+2), unilateral lower-limb pain (+3), hemoptysis (+2), and pain on deep venous palpation with unilateral edema (+4). Heart rate is the outlier — it is tiered rather than binary, contributing 0 points under 75 bpm, +3 points from 75-94 bpm, and +5 points at 95 bpm or above. Points sum to a maximum of 22, and the total is classified into three published probability tiers: Low (0-3, ~8% PE prevalence), Intermediate (4-10, ~29%), and High (11-22, ~74%).
What the tiers mean for next steps
The score is a triage tool, not a diagnosis. In the low and intermediate tiers, a negative D-dimer test is generally sufficient to exclude PE without imaging, avoiding unnecessary CT radiation and contrast exposure. In the high tier, pretest probability is high enough that D-dimer alone cannot safely rule out PE — imaging (typically CT pulmonary angiography) is indicated even with a negative D-dimer. The score does not replace clinical judgment, and unusual presentations (pregnancy, renal impairment limiting contrast use, or hemodynamic instability requiring immediate imaging) may call for a different pathway entirely.
