PURPOSE:

The ISPOR Value Flower continues to have a major impact on the assessment of value for healthcare technologies. The petals within the ISPOR Value Flower have become a mainstay in the health economics and outcomes research community, yet the novel methods to quantify each petal are not regularly implemented in value assessment today. This workshop provides a user guide on the novel methods to incorporate the petals within value assessment using a framework referred to as generalized cost effectiveness analysis (GCEA).

DESCRIPTION:

The workshop will begin with an overview of the GCEA framework. Dr. Shafrin will describe how value petals within this framework correspond to four value assessment themes: uncertainty, dynamics, value based on beneficiary identity, and other factors. Dr. Steuten will next discuss how the UK has tried to address these issues using decision modifiers around disease severity and other factors. Then, Professor Towse will explain how Generalized Risk-Adjusted Cost Effectiveness (GRACE) can be incorporated into GCEA to vary treatment value depending on disease severity. Next, Dr. Whittington will explain how stacked cohort models can be used to estimate long-run pricing dynamics, by incorporating genericization and pricing trends over time to more accurately capture the opportunity costs of healthcare interventions. Finally, Dr. Garrison will provide considerations for estimating value from the societal perspective in general and—more specifically—best practices for quantifying real option value. All three Discussants will provide applied examples of these methodologies. By the end of the session, the audience will understand the GCEA framework, which petals correspond to which broader value themes, and the fundamental steps and relevant references for estimating key GCEA petals. Real-time polling will be used to assess the attendees’ knowledge of which petals map to which themes and the methodological step ordering for the key GCEA value petals presented.
