Parents' Preferences for Drug Treatments in Juvenile Idiopathic Arthritis: A Discrete Choice Experiment

BACKGROUND: Parents of children with juvenile idiopathic arthritis (JIA) are often forced to make trade-offs between the effectiveness, convenience, safety, and cost of drug treatments for their child. METHODS: A discrete choice experiment was administered to parents of children with JIA to determine their preferences for drug treatments. Multinomial logit regression was used to estimate part-worth utilities and willingness-to-pay. RESULTS: Participation in daily activities was the most important attribute, followed by child reported pain. Child age, gender, years with JIA, and household income had the greatest impact on preferences. Parents’ were willing to pay $2,080 to switch from a drug representing methotrexate to etanercept (95% CI $698, $4,065). CONCLUSIONS: Parents of children with JIA have the highest maximum willingness-to-pay for drug treatments that improve daily functioning and reduce pain. Cost is a significant factor in the decisions that parents make surrounding the best treatment for a child.MAS
