Value clarity subscale
bleeding, VTE
EVENT, BLEEDING
The value clarity subscale informs on how clear it is to decide which benefits and risks matter more and how clearly it is to know what is most important (the benefits or the risks). This subscale had the lowest conflict score among all of the DCS subscales (mean = 19.70; SD = 15.76) and no significant differences were found between groups (All participants in Group 1 agreed that the information provided graphically about the probability of a VTE event or bleeding event occurring was clear enough to assess what matters most to them (benefits or risks). One participant (14%) added that the low certainty of the evidence was confusing when carrying out the tradeoffs of the decision. In Group 2, the majority (57%) used the content of the health states to know what benefits and what risks matter most; some participants (43%) highlighted the use of the value elicitation exercises to help them weigh the pros and cons of each health state and clarify what was more important. In Group 3, there was a discrepancy between the quantitative and the qualitative data; while this group showed the highest conflict for this subscale (mean = 22.91; SD = 20.77) of all three groups, their qualitative perceptions were that it was clear to them what matters most, risks or benefits. In addition, half of the participants (50%) reported the decision analysis model was useful and helpful to resolve imbalances and make a final decision.
