Wells Score for Pulmonary Embolism (PE)
Calculate the Wells score to estimate clinical probability of pulmonary embolism (PE). Components: clinical signs/symptoms of DVT (+3), PE is the most likely diagnosis (+3), heart rate >100 (+1.5), immobilization ≥3 days or surgery in last 4 weeks (+1.5), previous objectively diagnosed DVT/PE (+1.5), hemoptysis (+1), active malignancy (+1). Reports BOTH endorsed interpretations: three-tier (low <2 ~1.3%, moderate 2–6 ~16.2%, high >6 ~37.5%) and dichotomized two-tier (PE unlikely ≤4 ~12.1% — a negative D-dimer can rule out; PE likely >4 ~37.5% — imaging required). Derived from Wells 2001 (Ann Intern Med), ACEP 2018 clinical policy, and the ESC 2019 PE guideline. Pair with PERC and D-dimer. Not medical advice.
