Work through the components.

Enter age once. The worksheet assigns mutually exclusive age points for CHA₂DS₂-VASc and the separate age point for HAS-BLED. Select each applicable component; unchecked boxes contribute no points.

A total is not a treatment plan.

Read the linked source definitions before choosing components such as abnormal renal or liver function and labile INR. These classic scores are presented for learning. The worksheet deliberately does not convert totals into treatment instructions or a personal risk forecast.

Keep the curiosity going.
