摘要: AbstractObjective:Relapsing-remitting multiple sclerosis (MS) is usually managed with disease modifying drugs (DMDs), most commonly administered via self-injection. The aim of this study was to estimate the influence that different treatment-related attributes have for MS patients on their choice DMD device. By establishing relative importance these characteristics it should be possible better understand acceptability a given device and optimize development future devices.Methods:A discrete experiment (DCE) survey developed basis review published literature. Attributes identified inclusion in were: ease use; comfort presence additional functions, needle visibility; practicality efficacy. Choice sets were presented as pairs hypothetical treatments based upon fractional factorial design. One-hundred device-using completed online. Analysis conducted using mixed-logit appr...
