Abstract

Cutaneous lupus erythematosus (CLE) is a chronic skin disease that significantly impacts quality of life (QOL). This study tested a novel method to measure QOL in CLE using willingness-to-pay (WTP) stated preferences, and aimed to determine which of nine domains of life are most affected by CLE. Twenty-one participants with CLE ranked the domains in order of impact on CLE-related QOL, and then stated how many United States dollars they would be willing to pay for a hypothetical cure for each domain. Eighty-one percent of participants were female; mean age was 42.4 years. Photosensitivity was ranked highest by 71.4% of respondents. Participants were willing to pay the most for a hypothetical cure for CLE specific to photosensitivity (median = $200,000), the least for a cure specific to self-care (median = $0). Participants were willing to pay a median of $1,000,000 for an overall cure for CLE. Limitations include a small sample size for this pilot study and that willingness-to-pay may be influenced by individual perception of money and socioeconomic factors. This study successfully pilot-tested a WTP method and ranking task for health-related QOL. Photosensitivity was the domain of life most affected by CLE, which is a domain unique to our novel tool.
