Technology Assessment vs. Technology Appraisal-How to Strengthen the Science/Value Dichotomy with EU HTA?

Abstract

Many countries around the world use health technology assessment (HTA) to inform reimbursement and pricing decisions. HTA is often split into two steps, called assessment and appraisal. While the term HTA itself has been defined by international consortia, there is heterogeneity in the way different stakeholders use the terms assessment and appraisal. This creates ambiguity regarding which activities are included in technology assessment. With the new EU HTA Regulation, the HTA community should urgently seek to clarify the distinction between assessment and appraisal, as the regulation aims to centralize the clinical part of technology assessment at the European level. Failure to clarify this terminology will put the ambition of the regulation such as increased efficiency and reduction in duplication at risk. In this article, we argue that the distinction between assessment and appraisal should be seen as a science/value dichotomy. We discuss the transition from centralized assessment activities to country-level appraisal, which should culminate in a categorization of the overall added benefit in a local context. Finally, we touch on the important dimension of uncertainty always present in medical decision making.
