Wells score (pulmonary embolism)
Pretest probability of PE from seven clinical items.
Result
0
Three-tier: low probability. Two-tier: PE unlikely, D-dimer can rule out.
- Interpretation
- Anchors the D-dimer-versus-imaging decision to pretest probability.
- Limitations
- The 'most likely diagnosis' item is subjective by design; the score guides, it does not decide alone.
- Reference
- Wells PS et al. Thromb Haemost 2000;83:416-20.
