The validation assessment tool AdViSHE has been used to validate a cost-effectiveness model for frail older persons. In this model, Jonathan Karnon and colleagues present a  cost-utility analysis of a physiotherapy-based intervention for frail, Australian individuals. Validation of the cost-effectiveness model was attempted for each of the validation categories described in AdViSHE.

Face validity of the model structure, and model inputs and outputs was established through a detailed face-to-face presentation to clinicians, researchers and consumers.
Verification of the implemented models was performed using independent programming of different sections, extreme value testing. Cross validation was not possible, due to an absence of models to compare it to. Several outcomes were compared to previously published values.
