Assessment of the Validation Status of Health-Economic decision models (AdViSHE) is a tool that provides model users with a structured view into the validation status of the model, according to a consensus on what good model validation entails. It may also provide guidance towards additional validation. AdViSHE, may, for example, be part of dossiers sent to the (national) decision maker when applying for reimbursement, or it may be appended to manuscripts on modelling applications to support peer reviewers.
