Willingness to pay in arthritis: a Danish contribution
1University of Southern Denmark, Odense University, Institute of Public Health, Health Economics, Winsløwparken 19, 3, DK-5000 Odense C, Denmark.
Objective:
To explore the use of willingness-to-pay (WTP) methods with respect to an antagonist of tumour necrosis factor as an antirheumatic drug.
Methods:
One hundred and fifteen rheumatoid arthritis (RA) patients at a tertiary care centre in Odense, Denmark were interviewed using two WTP approaches, the contingent ranking and double-bounded (closed-ended) methods.
Results:
The average closed-ended WTP value was DKr581 and the average contingent ranking WTP was DKr643. There were no statistically significant differences in the WTP estimates between the two methods.
Conclusion:
It is feasible to use these methods with arthritis patients. If, as suggested in a number of recent reviews, a major effort is to be put into undertaking economic appraisals of arthritis programmes, then this should include more cost-benefit studies using WTP approaches of the kind illustrated in this paper.
