Good practices in health care research are continually evolving. Recently, there have been methodological advances in stated-preference methods.
RTI Health Solutions’ Brett Hauber was part of a team of researchers that created a study to consolidate and illustrate good practices for research that involves measuring patient preferences for type 2 diabetes medications.
ISPOR-recommended practices, as well as other recommendations, were used in the study, Conducting a discrete choice experiment study following recommendations for good research practices: an application for eliciting patient preferences for diabetes treatments. The research identified how patients valued different methods of medication administration and outcomes. Study results also demonstrated that people strongly prefer immediate consequences with medications.
Despite efforts to produce recommendations for research practices, ambiguity surrounding good practices remains, and researchers must exercise judgment when conducting stated-preference studies. They should describe and justify these judgments to ensure transparency.
