What factors influence international normalized ratio (INR) stability and pharmacological adherence in patients taking oral anticoagulants?
In patients on oral anticoagulants, shorter anticoagulation time and lower drug costs are associated with better adherence and higher INR stability.
Ávila et al. (2011) conducted a cross-sectional in Patients on oral anticoagulants (n=156). Oral anticoagulant therapy was evaluated on INR stability. Shorter anticoagulation time and lower drug cost were associated with better INR stability among 156 patients on oral anticoagulants, of whom over 90% demonstrated high or medium adherence.
