Oral anticoagulation therapy upon discharge in hospitalized patients with nonvalvular atrial fibrillation: a retrospective cohort study.

Decision to add OACT is often guideline-driven, however, individualized circumstances in which clinicians and patients find themselves are also important considerations. Determination of ischemic stroke risk should be performed with CHA2DS2VASc scoring tool to exclude patients who may not benefit from OACT. HAS-BLED scoring tool should be used to identify any modifiable bleeding risk factors present with subsequent initiation of management strategies. Availability of complete medical histories and meticulous documentation are necessary for multiple clinicians to continuously determine optimal pharmacotherapy during follow-up visits.
