The International Patient Decision Aid Standards recommends that patient decision aids (PtDAs) include a value clarification method (VCM). The audience will learn about the current use of MCDA and other preference elicitation methods as VCMs, their feasibility and effectiveness in practice, and about novel applications that may overcome some of the limitations of frequently used health preference methods, such as discrete choice experiments (DCEs).

Dr. van Til will provide examples of frequently used methods identified in the SIG's systematic literature review and discuss how attribute importance and preferences for options are quantified. Interactive polling will be used to elicit attendees’ attitudes about using preference elicitation methods as VCM, then compare attendee attitudes with the evidence in literature.

Dr. Poulos will discuss development of a VCM using object-case best-worst scaling to support patient decision making on treatment of primary immunodeficiency diseases. She will describe how the formative research process influenced the design of the PtDA.

Ms. Thomas will outline how multi-dimensional thresholding can be used as a VCM with patient-specific outputs provided in a PtDA. She will walk through an example of the process for a patient and the types of outputs that could be provided.

Speakers will address the potential of preference elicitation methods as a VCM, areas requiring additional research (eg, recommending a treatment option based on preferences), and challenges (eg, in generating individual preference estimates with some methods). Audience discussion will follow the case study examples. Presented by the ISPOR Health Preference Research Special Interest Group
