Calculates probability of Pulmonary Embolism
Total Score
Low risk (PE probability < 5%). Consider PERC rule or D-Dimer.

The Wells Criteria for Pulmonary Embolism (PE) stratifies patients into risk categories (historically Low/Moderate/High, currently often simplified to PE Unlikely / PE Likely) to guide further diagnostic workup. It is a cornerstone algorithm that effectively pairs clinical gestalt with objective risk factors to prevent over-utilization of CT Pulmonary Angiography (CTPA).
The criterion 'Alternative diagnosis less likely than PE' carries the most weight (3 points) and is entirely subjective. This demands careful clinical assessment to actively rule out conditions like pneumonia, pneumothorax, or musculoskeletal pain before defaulting to a PE workup.
