Patient-Centered Tablet Application for Improving Medication Adherence after a Drug-Eluting Stent

Area of Science:

• Consumer Health Informatics
• Digital Health Interventions
• Patient Engagement Technologies

Background:

• Drug-eluting stents (DES) require adherence to dual antiplatelet therapy (DAPT) for optimal outcomes.
• Improving patient knowledge and adherence to DAPT is crucial for managing cardiovascular health post-DES.
• Traditional methods may not fully engage elderly patients in their DAPT regimen.

Purpose of the Study:

• To evaluate the efficacy of a patient-centered educational tablet application, MyIDEA.
• To assess if MyIDEA increases patient knowledge of DAPT and improves medication possession ratio (MPR) compared to standard care.
• To explore the impact of a digital health tool on patient engagement in managing DAPT.

Main Methods:

• A pilot study involving 24 elderly participants (≥50 years) post-DES implantation.
• Randomized controlled trial with 11 participants in the control group and 13 in the intervention group using MyIDEA.
• Assessment of adherence via MPR at 3 months and administration of psychological and knowledge questionnaires.

Main Results:

• The MyIDEA group showed a 10% average increase in MPR compared to the control group.
• Fewer patients in the intervention group exhibited poor adherence (<80% MPR) than in the control group.
• Interventional participants spent an average of 21 minutes using the MyIDEA application.

Conclusions:

• Patient-centered consumer health informatics tools like MyIDEA can effectively engage patients with their health data.
• Digital health technologies focusing on patient knowledge and engagement are vital for improving long-term health outcomes.
• MyIDEA uniquely targets DAPT adherence from the outset, empowering patients as active healthcare team members.
