Atrial fibrillation (AF) can lead to a significant health and economic burden to society. This study aimed to assess the net budget impact of direct-acting oral anticoagulants (DOACs) instead of warfarin for stroke prevention in patients with non-valvular AF from the payer’s perspective.

A budget model over a 5-year period was used. Dabigatran 150 mg, dabigatran 110 mg, apixaban 5 mg, rivaroxaban 20 mg, edoxaban 60 mg, and edoxaban 30 mg were included. Inputs were retrieved from published literature. Adoption rate of DOACs started at 5% and subsequently had a 5% increase in each year. Net budget impact (NBI) and sensitivity analyses were performed.

The average NBI over the 5-year horizon for all DOACs ranged from 12.3 M USD to 13.9 M USD. Dabigatran 150 mg had the highest NBI, while edoxaban 30 mg had the lowest NBI. The average NBI/patient/year ranged from 63.03 USD – 70.75 USD.

Of all DOACs, edoxaban 30 mg, apixaban 5 mg, and edoxaban 60 mg are the top 3 lowest NBI. Together with cost-effectiveness evidence, those DOACs should be considered to be listed on the National List of Essential Medicine in Thailand.
