Summary

Among patients with acute coronary syndrome (ACS) treated with percutaneous coronary intervention (PCI) and stent implantation, 17.5% are both at high bleeding risk (HBR) and have undergone complex PCI, which also places them at high thrombotic risk. In this population, several dual antiplatelet therapy (DAPT) strategies may be considered: (1) de-escalation of DAPT intensity after 1 to 3 months (switch from ticagrelor/prasugrel to clopidogrel), (2) shortening DAPT duration to 1 to 3 months followed by antiplatelet monotherapy, (3) 12-month clopidogrel-based DAPT, and (4) 12-month ticagrelor/prasugrel-based DAPT. Selecting the most appropriate DAPT strategy in this dual-risk context is complex, and clinical trial evidence is limited for this specific subgroup. In the absence of clear guideline recommendations to support decision-making for patients facing both elevated bleeding and thrombotic risks, structured shared decision-making support is needed.

In this context, within research project 2025-3499 conducted with pharmacy residents, we developed a patient decision aid (PDA) designed to support shared decision-making by helping patients understand their risks, available options, and potential consequences, so they can express their preferences regarding antiplatelet therapy. The PDA aims to facilitate shared decisions by improving patients' understanding of benefits and harms and aligning choices with patient values. A preliminary version of the tool has already undergone alpha testing with a small group of internal users (physicians, pharmacists, and patient partners). The next step is beta testing, that is, real-world testing with the target population and clinicians to evaluate usability and acceptability in routine practice.
