title: Retrospective costing of warfarin.
abstract: In Ireland, there are four anticoagulants available for prescribing to patients with atrial fibrillation for stroke prevention. A key feature of the three most recent anticoagulants is that monitoring is redundant. Despite this, there is continued prescribing of the incumbent anticoagulant, warfarin, which requires monitoring. Lack of information regarding the cost of monitoring, and the extra burden it places on health budgets and patients, motivated this costing study. Using micro costing, the costs of warfarin treatment (including monitoring) was disaggregated and isolated from both the patients' and health care provider's perspectives in a Cork hospital. Costs to the health care provider per patient per clinic visited were 21.57 Euros. Patient costs incurred per patient per clinic were 48.50 Euros. Thus, the total costs per patient per visit were 70.07 Euros. This result reveals that while the pharmaceutical cost of warfarin is low; it is not an inexpensive therapy when monitoring costs are considered.
