Finnish Digi-HTA Assessment Model for Digital Health and an International Comparison

Abstract

New health technology assessment (HTA) models for digital health are continuously being developed and are already in use. In Finland, the HTA model for digital health, named Digi-HTA, has been employed since 2020. Internationally and also in Finland, the need for harmonization of these HTA models has been recognized. In order to harmonize the models, it is necessary to first identify the key features and requirements of existing models. In this study, three key assessment models for digital health identified as central in the Finnish context were analyzed. After the analysis, the results were compared to the Finnish Digi-HTA assessment model, and a final synthesis was created regarding the similarities and differences between the assessment models. The comparison includes German DiGA model, the global CEN-ISO/TS 82304-2:2021 technical specification, and the Nordic-designed NordDEC assessment model. There was a great deal of similarity in the evaluated models, although certain differences in emphasis were found. The key differences relate to reimbursement process, maturity of the assessment process and supported product categories as well as cost and effectiveness evaluation. The results of this study can be utilized in harmonizing assessment models for digital health.
