Patient Centered Tablet Application for improving medication adherence after a Drug Eluting Stent

Background/Aims: This study’s objective was to evaluate a patient-centered educational electronic tablet application, My Interventional Drug-Eluting Stent Educational App (MyIDEA) to see if there was an increase in patient knowledge about dual antiplatelet therapy (DAPT) and medication possession ratio (MPR) compared to treatment as usual. Methods: In a pilot project, 24 elderly (≥50 years-old) research participants were recruited after a Drug Eluting Stent. 11 were randomized to the control arm and 13 to the interventional arm. All participants completed psychological and knowledge questionnaires.

As compared to the interventional group, more patients in the control group had poor adherence (
