On the normativity of evidence - Lessons from philosophy of science and the "VALIDATE" project.

"Evidence" is a key term in medicine and health services research, including Health Technology Assessment (HTA). Randomized clinical trials (RCTs) have undoubtedly dominated the scene of generating evidence for a long period of time, becoming the hallmark of evidence-based medicine (EBM). However, due to a number of misunderstandings, the lay audience and some researchers have sometimes placed too much trust in RCTs compared to other methods of investigation.

Integrating Empirical Analysis and Normative Inquiry in Health Technology Assessment: The Values in Doing Assessments of Health Technologies Approach.

Health technology assessment (HTA) aims, through empirical analysis, to shed light on the value of health technologies (O'Rourke et al. [2020, 36, 187-90]). HTA is, then, where facts and values meet.

Learning and practicing more value-reflective, problem-setting health technology assessment: experiences and lessons from the VALIDATE project.

Objectives: To conduct a formative evaluation of applying the VALIDATE approach in practice by (i) assessing how students appreciated the e-learning course, (ii) exploring how, for what purposes and with what outcomes the acquired VALIDATE competences subsequently were used in internships in different institutional contexts, and how this was shaped by these contexts, and (iii) what this shows on real-world use of VALIDATE.

Methods: Comparative discussion of experiences of applying the VALIDATE approach via a semistructured survey and oral feedback from e-course students; final reports on internships in health technology assessment (HTA) practice, followed by semistructured interviews with interns and supervisors to complement and interpret results.

Results: All students considered the VALIDATE approach an enlightening and important addition to current HTA knowledge, especially regarding understanding the relation between empirical analysis and normative inquiry, identifying policy relevant questions and using the method of reconstructing interpretive frames for scoping.

Prioritization of COVID-19 vaccination. The added value of the "VALIDATE" approach.

Prioritization of COVID-19 vaccines is one of the most relevant topics in the current pandemic emergency. Prioritization decisions are political decisions that are value-laden, and as such of ethical nature. Despite the clear political and ethical nature of this topic, prioritization decisions are often interpreted and presented as scientific decisions.
