Abstract
The appropriate development of a model begins with understanding the
problem that is being represented. The aim of this article was to provide a
series of consensus-based best practices regarding the process of model conceptualization.
For the purpose of this series of articles, we consider the development
of models whose purpose is to inform medical decisions and
health-related resource allocation questions.
We specifically divide the conceptualization
process into two distinct components: the conceptualization
of the problem, which converts knowledge of the health care process or decision
into a representation of the problem, followed by the conceptualization
of the model itself, which matches the attributes and characteristics of a
particular modeling type with the needs of the problem being represented.
Recommendations are made regarding the structure of the modeling team,
agreement on the statement of the problem, the structure, perspective, and
target population of the model, and the interventions and outcomes represented.
Best practices relating to the specific characteristics of model structure
and which characteristics of the problem might be most easily represented
in a specific modeling method are presented. Each section contains a
number of recommendations that were iterated among the authors, as well
as among the wider modeling task force, jointly set up by the International
Society for Pharmacoeconomics and Outcomes Research and the Society for
Medical Decision Making.
Keywords: conceptualization, best practices, methods, modeling.
