Abstract
Objective: To assess the willingness to pay (WTP) for treatment in a spa resort of patients with ankylosing spondylitis (AS) and to assess if the experience of a spa influences the WTP.
Methods: 120 patients participating in a randomised trial comparing 3 weeks’ treatment in a spa resort in Austria or in the Netherlands with a control group completed a WTP questionnaire before and after spa treatment. Patients indicated on a payment card the maximal co-payment they wanted to contribute for three scenarios that included (a) two levels of improvement in pain and stiffness and (b) two treatment environments: a rehabilitation hospital and a spa resort.
Results: At baseline, patients wanted to contribute more for the same improvement after treatment in a spa resort compared with a rehabilitation hospital (p<0.003), and were prepared to pay more when expected effects were higher (p<0.001). No differences were found between men and women, pain, or income. After the trial none of the treatment groups showed a change in their WTP.
Conclusion: The WTP of patients with AS for inpatient treatment is influenced by the treatment environment and the expected improvement. Experiencing treatment in a spa resort does not influence the co-payment.
