Main findings
In this study, we aimed to report participant’s perspectives on using an SDM intervention to reduce decisional conflict of a preference-sensitive decision; the use of thromboprophylaxis during pregnancy. Our main finding is that all three components of the SDM intervention (evidence-based information, value elicitation exercises and decision analysis) reduce the overall decisional conflict. We found no decisional conflict (DCS < 25) for the overall DCS score and the majority of the subscales, for all three groups; however, this trend was not statistically significant. We found a high level of decisional conflict (> 37.5) for the uncertainty subscale due to the low certainty of the evidence, however value elicitation exercises showed to have the potential to reduce the uncertainty of the process.
