Eliciting implicit value-judgments (VJs) in the HTA process is one way of integrating ethics in HTA since the latter is recognized as a value-laden process. An analysis of the diversity of opinions on implicit VJs in HTA and of their role, highlights the connection there exists between VJs and the different decisions involved in the whole HTA process. Such a link is corroborated by a conceptual analysis of VJ using a speech-act philosophical approach grounded in the philosophy of language, since VJs are linked with normative speech-acts such as commands, recommendations and advices.

We propose an analysis of the published citations mentioning VJs, extracted from our systematic review on the challenges of integrating ethics in HTA. In order to do so, those quotes were categorized in a chart, the latter of which presents: (i) the different steps of decision-making in the HTA process, (ii) the description of the implicit VJ(s) and (iii) the criteria involved. This chart was elaborated with the participation of the HTA local evaluators involved as co-investigators in our research group. The final version was discussed, debated and validated by the entire research group.

The chart shows 18 decision-making steps in the HTA process in which twenty-three implicit VJs can be observed. The range of such VJs encompasses the whole HTA process from the initial mandate to the agency presenting the decisional issues, to the dissemination of the final report. The published citations gathered for each category compile different expectations on the elicitation of the implicit VJs, thus making the latter VJs more explicit.

This chart allows a better understanding of the expectations that are at the core of the appeal for more transparency in the HTA process, since stakeholders need to understand which value-judgments the final conclusion of a report is relying on.
