Objectives: The aim of this study is to analyze inherent value and factors which influence willingness to pay (WTP) of vasomotor symptoms (VMS) treatment in Korea.
Methods: The nationwide, cross-sectional, face to face survey was conducted on 1500 menopausal women above age of 40. Respondent provided data which included educational attainment, employment and marital status, monthly household income, and other demographic information. Among 1500 respondents, 657 (43.8%) reported experiencing VMS in the previous 6 months. The 657 respondents completed interview for their WTP for VMS treatment regarding a specific amount of money to return to patient’s pre-VMS health status through 3 times of bidding games. Starting bids were 10000 KRW, 30000 KRW, 50000 KRW, and 100000 KRW. Following bidding games, respondent was asked an open ended question directly asking them to provide maximum WTP. Predictors of open-ended maximum WTP and that of first bid acceptancy were evaluated using linear regression models and logistic regression models, respectively.
Results: Average monthly WTP for a hypothetical treatment to return current state to their pre-VMS state was 43463 KRW. The factors having a significant effect of patient WTP for VMS treatment are income, amount of current expenditure for VMS management and initial starting bid. As the ability to pay increases, the patient is willing to pay more for a treatment that will return them to their pre-VMS health state. Recognition of necessity of menopausal symptom management also resulted in a increase in patient WTP. WTP was closely associated with initial starting bid (p<0.001). WTP results were higher with higher starting bids.
Conclusion: Average monthly WTP was 43463 KRW. The main factors to influence to increase WTP were income, amount of current expenditure for VMS management and starting bid in bidding game.
