Anticoagulation (ECAA): Studies on Computer-Assisted Anticoagulant Dosage.

The worldwide increase in the scale of oral anticoagulant treatment in recent years has followed publication of clinical reports demonstrating their value in a widening spectrum of disorders[1]. A 10% increase per annum is estimated for EU countries[2]. Increased benefit/risk ratio resulting from lower dose oral anticoagulant administration combined with implementation of the WHO INR system of prothrombin time standardisation of laboratory control has played a part in this development.
