Revised Geneva Score: Pulmonary Embolism Calculator

Clinical Interpretation & ESC Recommendations

Pulmonary Embolism (PE) is a diagnostic and therapeutic cardiovascular emergency. The Revised Geneva Score is a globally validated clinical prediction rule that stratifies the pre-test probability of PE in suspected patients, guiding the diagnostic strategy.

Advantage of the Geneva Score over Wells

Unlike the Wells score, which includes a highly subjective criterion ("Alternative diagnosis less likely than PE?"), the Revised Geneva Score relies exclusively on eight entirely objective clinical variables (history, age, heart rate, hemoptysis, DVT signs). This objectivity makes it much more reproducible among different physicians, making it an ideal, standardized tool for Emergency Departments (ED).

2-Tier (Dichotomous) Model

Historically, the score stratified patients into three categories (low, intermediate, high). However, current European Society of Cardiology (ESC) guidelines favor the use of the dichotomous (2-tier) model to simplify and secure medical decision-making. A score of 0 to 5 indicates PE is unlikely (indication for D-dimer testing). A score ≥ 6 indicates PE is likely, justifying immediate CT pulmonary angiography (CTPA) without D-dimer testing.

• Score 0 - 5 (PE Unlikely): D-dimer testing is the first-line investigation. If D-dimers are negative, PE is safely excluded without imaging (NPV > 99%).
• Score ≥ 6 (PE Likely): D-dimer testing is useless (false-positive rate is too high in this population). Proceed directly to diagnostic imaging, generally a CT pulmonary angiography (CTPA).
