Abstract
Objective: We assessed willingness-to-pay (WTP) and time trade-off (TTO) as methods to quantify the disease burden of benign hyperpigmentation. Design: This was a cross-sectional pilot study that included 85 adults. A paper survey was used to collect demographic and health utility information; an accompanying dermatological exam assessed disease severity. Setting: This was a single-site study performed at an urban dermatology clinic. Participants: Adults 18 years of age or older who spoke English, Spanish, or Portuguese were included. Measurements: Utility measures included WTP, TTO, and time spent concealing the condition; correlation with quality of life was also assessed. Results: Mean WTP for 25-percent improvement (WTP25) of the skin condition was $38.95; for a 50-percent improvement (WTP50), $83.18. Participants were willing to give up 1.4 hours per day to receive a therapy that would completely cure their condition. The average proportion of monthly income that participants were willing to spend on a therapy that could cure their condition was 13.3 percent. Daily concealment time was, on average, 20.8 minutes, which correlated with a worsened quality of life. Conclusion: Disease burden was high, overall, for benign hyperpigmentation conditions. Health utilities offer a patient-centered method of assessing impact on quality of life.
