The aim of this study is to evaluate patients’ preferences for self-injection devices in RA, and to elicit their willingness to pay (WTP) for injector devices in China.Methods: RA patients were recruited from Beijing, Shanghai, Guangzhou, Chengdu, Wuhan and Xi’an in China. A discrete choice experiment (DCE) was employed to elicit patient preferences. Patients were presented with 15 choice sets that consisted of seven attributes, which were developed based on literature review and further validated by physicians. The seven attributes were as follows: operation steps, injection pain, feedback indication, needle visibility, needle protection, size and out-of-pocket costs. A mixed logit model was used to analyze the relative importance of seven attributes and to calculate the WTP for a changed attribute level.Results: Analyses included 114 adults with RA (mean age of 44.6 years old). When choosing the injection device, all attributes had significant influence. Among nonmonetary attributes, very slight injection pain was the most preferred for patients, followed by auto-injection method, thicker size, hidden needle, with needle protection and multiple feedback indication. Patients had a negative preference for increasing out-of-pocket costs. Patients were willing to pay CNY 45.26 for improving slight injection pain to very slight injection pain, CNY 13.26 for the auto-injection method, CNY 12.22 for the thicker size, CNY 10.06 for the hidden needle, CNY 9.82 for needle protection, and CNY 9.70 for multiple feedback indicators.Conclusion: The results suggested that injection pain was the most important attribute for RA patients. Meanwhile, all other enhanced attributes of self-injection devices also significantly influence patients’ selection on injection devices. Findings suggested that there is significant potential value in developing self-injection devices that could further help improve treatment adherence and promote patient-centered care in autoimmune diseases.Keywords: self-injection devices, rheumatoid arthritis, patient preferences, discrete choice experiment |
