Baber et al reported a score for predicting major bleeding following percutaneous coronary intervention (PCI). The authors are from multiple institutions in the United States, Europe and Israel participating in the PARIS study (Patterns of Non-Adherence to Anti-Platelet Regimen in Stented Patients).
Patient selection: PCI
Outcome: major bleeding
Parameters:
(1) age in years
(2) body mass index in kg per square meter
(3) current smoking
(4) anemia
(5) creatinine clearance in mL per min
(6) triple therapy on discharge

total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 14
• The higher the score the greater the risk of bleeding.
