★ DoctorScribe — Complete Clinic Management
Track every AF patient's score over time
DoctorScribe recalculates CHA₂DS₂-VASc and HAS-BLED at every visit, alerts when scores cross treatment thresholds, and stores anticoagulant trial history — built-in stroke prevention.
Clinical Disclaimer: Score applies to non-valvular AF only. For mechanical valves or moderate-severe mitral stenosis, oral anticoagulation is indicated regardless of score. Always balance with HAS-BLED bleeding risk and patient preference. Always verify against your local prescribing reference and apply clinical judgment.
Anticoagulation decisions, automated
DoctorScribe auto-calculates CHA₂DS₂-VASc and HAS-BLED on every AF patient, flags interactions when prescribing DOACs, tracks INR for warfarin patients — all inside the chart.
