CHE Fellowship Seminar - Evidence Elasticity in Value of Information Analysis
Event details
Abstract:
Value of information analysis is a useful framework for assessing whether future research is worth conducting by estimating the expected value of reducing decision uncertainty. However, standard approaches often assume that, once new evidence becomes available, the treatment with the highest expected net health benefit will be perfectly adopted. They also often do not distinguish between policy-level and physician/patient-level decisions, which may have different objective functions. In practice, coverage and clinical decisions may respond to new evidence to varying degrees, depending on the findings and design of the study. In this work, we introduce the concept of “evidence elasticity” to characterise responsiveness to evidence at the two levels and examine how it may affect the estimated value of information. We further consider scenarios involving non-binary coverage and treatment effect heterogeneity. The seminar will present the theoretical framework, followed by an illustrative case study.
