Revised Geneva Score
Calculate the Revised Geneva Score to assess pulmonary embolism probability using 8 clinical criteria. Free PE risk assessment tool with 2-level and 3-level classification.
About This Calculator
The Revised Geneva Score Calculator helps clinicians and patients assess the probability of pulmonary embolism (PE), a serious condition where a blood clot blocks a pulmonary artery. This score uses eight objective criteria — age, prior DVT/PE history, recent surgery or fracture, active cancer, unilateral leg pain, hemoptysis, heart rate, and leg edema — to categorize PE risk without requiring subjective clinical judgment.
The scoring system was developed by Le Gal et al. in 2006 and validated across multiple populations. Each criterion carries a specific point weight, and the total score is interpreted using both a two-level system (PE unlikely vs. probable) and a three-level system (low, intermediate, high risk). Patients classified as low or intermediate risk should undergo D-dimer testing, while high-risk patients require urgent CT pulmonary angiography. Studies show the Revised Geneva Score has similar diagnostic accuracy to the Wells Score but offers greater reproducibility due to its fully objective criteria.
Regional Notes
India: The Revised Geneva Score is used in Indian emergency departments and tertiary care centers alongside D-dimer (ELISA or quantitative) and CT pulmonary angiography. The Indian Council of Medical Research (ICMR) guidelines recommend validated clinical prediction rules for PE assessment.
United States: Widely used in US emergency departments. The American College of Emergency Physicians (ACEP) clinical policy supports the use of structured PE risk assessment tools. D-dimer testing with age-adjusted cutoff (age × 0.1 mg/L for patients >50 years) is commonly applied.
United Kingdom: NICE guideline NG158 recommends the two-level Wells Score for initial PE assessment, but the Revised Geneva Score is an accepted alternative. The UK approach emphasizes D-dimer testing in low-risk patients and direct imaging in high-risk patients.
Frequently Asked Questions
What is the Revised Geneva Score?
The Revised Geneva Score is a clinical prediction rule developed in 2006 to assess the probability of pulmonary embolism (PE) in emergency department patients. It evaluates 8 risk factors and clinical findings — age over 65, prior DVT/PE, recent surgery or fracture, active cancer, unilateral leg pain, hemoptysis, heart rate, and unilateral leg edema — to categorize PE risk as low, intermediate, or high.
How is the Revised Geneva Score calculated?
Each criterion is assigned points: age >65 (1), prior DVT/PE (3), surgery/fracture within 1 month (2), active cancer (2), unilateral leg pain (3), hemoptysis (2), heart rate 75–94/min (3), heart rate ≥95/min (5), unilateral leg edema or pain on deep vein palpation (4). The total score ranges from 0 to approximately 22.
What do the Revised Geneva Score results mean?
The score uses two classification systems. 2-level: 0–5 = PE unlikely (16% probability), ≥6 = PE probable (38% probability). 3-level: 0–3 = low risk (8–10% PE probability), 4–10 = intermediate risk (22–28%), ≥11 = high risk (48–74%). Low and intermediate risk patients need D-dimer testing; high risk patients require urgent CT imaging.
How does the Revised Geneva Score differ from the Wells Score?
The Revised Geneva Score relies entirely on objective clinical criteria and does not require clinician judgment, unlike the Wells Score which includes a subjective assessment of whether an alternative diagnosis is less likely than PE. Both have similar diagnostic accuracy, but the Geneva Score is considered more standardized and reproducible across different clinicians.
Is the Revised Geneva Score used in US, UK, and Indian hospitals?
The Revised Geneva Score is used worldwide. In the US, both the Wells Score and Revised Geneva Score are commonly employed in emergency departments. UK hospitals (NHS) frequently use the two-level Wells Score but the Geneva Score is also recognized. In India, many tertiary care hospitals use these scoring systems alongside D-dimer testing and CT pulmonary angiography for PE diagnosis.
Can this calculator replace a doctor's diagnosis?
No. This calculator is for educational and reference purposes only. Pulmonary embolism is a life-threatening condition that requires immediate medical evaluation by qualified healthcare professionals. The Revised Geneva Score is a screening tool and should always be used in conjunction with clinical assessment, D-dimer testing, and appropriate imaging.
What is the Simplified Geneva Score?
The Simplified Geneva Score, created in 2008, assigns 1 point to all criteria (except heart rate ≥95/min which gets 2 points) instead of the weighted scoring of the Revised Geneva Score. The simplified version is easier to remember and has similar predictive accuracy for pulmonary embolism risk assessment.
What happens after the Revised Geneva Score is calculated?
For patients with low or intermediate probability (2-level: 0–5 points), a D-dimer blood test is recommended. If D-dimer is elevated, CT pulmonary angiography is needed. For high probability patients (2-level: ≥6 points), direct CT pulmonary angiography is indicated without D-dimer testing. Prompt diagnosis and treatment reduce PE mortality from 30% to approximately 2%.
