Abstract

Patient and public involvement (PPI) in health economics modelling is an increasingly recommended practice. However, guidelines or ‘best practices’ for PPI in modelling have yet to be developed and modelling teams must determine how to structure the PPI process, track its impact, and document challenges. This is one objective in the Lifetime Exposures and Asthma Outcomes Projection (LEAP) model project, a multi-year initiative to develop a 'Whole Disease' model of asthma. Building on philosophical theory, we developed the Values in Modelling (VIM) framework to help structure the PPI process in the LEAP project and guide future work in this area. In this article, we describe the VIM framework and our process of implementing it in a recent phase of the LEAP project, focused on modelling the cost-effectiveness of high-efficiency particulate air (HEPA) air cleaners for asthma prevention and management. Using specific examples, we illustrate how the VIM framework guided the modelling team’s deliberations and how participators in modelling influenced shared determinations concerning the ‘best’ (most adequate-for-purpose) modelling decisions.
