Wells score for pulmonary embolism.

Tick the seven bedside criteria documented on this encounter. Total, risk tier, and pre-test probability update live — then copy or print a clean clinical summary. The Wells-DVT calculator is a separate page with its own criteria set.

Informational only. Not a substitute for clinical judgement. Not a patient record — Wells scores are not persisted; a refresh clears the result. Population-level estimates; always follow your institution’s PE protocol and risk-stratify with imaging and clinical gestalt.

7-point Wells criteria

Tick the items clinically documented on this encounter. Total updates live; pre-test probability uses the simplified/modified bands.

Clinical signs of DVT (3.0 pt)

Minimum of leg swelling + pain on palpation of deep veins

Objectively documented — not unilateral calf discomfort alone.

PE the #1 diagnosis (or equally likely to alternative) (3.0 pt)

"Alternative diagnosis less likely than PE" on the gestalt line

The gestalt column — clinically the most heavily weighted item.

Heart rate > 100 bpm (1.5 pt)

Documented tachycardia at rest

Use the documented value, not a recounted estimate.

Immobilization ≥ 3 days OR surgery in previous 4 weeks (1.5 pt)

Bedrest, casting, long-haul flight within the preceding month

Either limb qualifies — pick the one the chart supports.

Previous, objectively diagnosed DVT or PE (1.5 pt)

Documented (not self-reported) prior venous thromboembolism

A history of clot counts even on chronic anticoagulation.

Hemoptysis (1.0 pt)

Coughing up blood — frank or blood-streaked sputum

Single weight; rarely the only finding but flips a moderate band.

Active malignancy (1.0 pt)

On treatment, within 6 months, palliative, or recently diagnosed

Remission off therapy > 6 months does not count.

Documentation

Wells score 0.0 — low pre-test probability for PE (~4%); consider D-dimer or no further PE workup per clinician judgment.

Not persisted — refreshing clears the result.
