What is the stepwise approach to thromboprophylaxis?
The stepwise approach to thromboprophylaxis involves initially identifying low risk patients using the CHA2DS2-VASc score (Step 1), followed by offering stroke prevention to all other patients (Step 2) irrespective of stroke point score or biomarkers used. This approach uses stroke risk scores in a reductionist manner to aid decision-making, and balances simplicity and practicality (and costs).
