Introduction: In an earlier study, we described and validated a VKA dose-finding algorithm (B2A), based on a novel bidirectional factor (BF). We designed a prospective study to evaluate the B2A in a daily care setting. 
Methods: In this open-label prospective study, we compared the outcomes of the B2A over the year 2020 with the outcomes of the previous year (2019), using regular algorithms. The outcomes were the duration of Time in the Therapeutic Range (TTR), the percentage of automated dose proposals (PAuP) and the percentage of accepted dose proposals (PAcP). The data were obtained from three anticoagulation centers in the Netherlands, in four locations. The outcomes of this study were based on a non-inferiority level.
Results: The TTR over the year 2020 was at least non-inferior compared with the standard of care treatment. The percentage of automated proposals increased in all centers to approximately 96% of all dosages. 
Conclusion: The B2A performs non-inferior compared with the existing algorithms and in some aspects even better.
