RIETE Score for Risk of Hemorrhage in Pulmonary Embolism Treatment
Recent major bleeding (within prior month)
Active cancer
Creatinine >1.2 mg/dL
Anemia (Hb <13 g/dL men, <12 g/dL women)
Age >75 years
Clinically overt pulmonary embolism (rather than isolated DVT)
Result0.0 points
Estimated major bleeding risk in the first 3 months of anticoagulation: ~0.3 %.
- Risk category
- Low
When to use
- Weighing bleeding risk against benefit before starting or continuing anticoagulation for acute VTE.
Formula
Points: recent major bleeding 2, cancer 1, creatinine >1.2 mg/dL 1.5, anemia 1.5, age >75 1, overt PE 1. Low risk 0, intermediate 1-4, high >4.
Pearls and pitfalls
- Captures only baseline risk at anticoagulation initiation; does not account for interval clinical changes.
