Summary
Background and objective: Knowledge of the costs of oral anticoagulant (AC) treatment may be relevant for resource
allocation. Also, the incremental costs may be compared with other treatments for
health care policy decisions. In this report, we have assessed actual costs of anticoagulant
therapy in anticoagulation clinics (AC-clinic) in three different settings in the
Netherlands. Methods: Costs of anticoagulant drug supply and costs as a result of INR-adjustment procedures
were estimated. We compared the total costs of treatment in patients treated after
minor cerebral ischaemia in the Stroke Prevention in Reversible Ischemia Trial (SPIRIT)
and in patients treated because of peripheral arterial occlusive disease in the Dutch
Bypass Oral anticoagulants or Aspirin Trial (BOA). Results: Costs of monitoring ranged between Euro 6.44 and Euro 9.87 per visit for monitoring
at the AC-clinic and at home, respectively. The annual costs of administering anticoagulant
drugs ranged between Euro 83 (phenprocoumon) and 107 (acenocoumarol). Variation in
the overall actual annual costs of AC treatment was caused by the number of monitoring
visits, the distribution of home and clinic visits and, to a lesser extent, the medication
used. Annual costs of AC therapy for patients in SPIRIT was Euro 239 and for patients
in BOA Euro 312. Overall costs of anticoagulant therapy were about 3 to 4-fold higher
than standard treatment with aspirin. Conclusions: Although the actual costs of anticoagulant therapy may be substantially higher than
that of other antithrombotic therapies, its cost-effectiveness depends highly on efficacy.
