Clinical Trial Summary

The purpose of this study is to determine whether text messages/messaging (TM) or a mobile application (app), compared with an educational website-control provided to all Veterans, can improve adherence to antiplatelet therapy among patients following acute coronary syndrome or percutaneous coronary intervention (ACS/PCI).

Description:

Adherence to antiplatelet medications is critical to prevent life threatening complications (i.e., stent thrombosis); yet rates of non-adherence range from 21-57% by 12 months. Mobile technology through TM or mobile apps is a practical and inexpensive strategy to promote behavior change and enhance medication adherence. The three specific aims of this proposal are to: 1) determine preferences for content and frequency of TM to promote medication adherence through focus groups; 2) determine the most patient-centered app to promote adherence through a content analysis of all commercially available apps for medication adherence and focus groups centered on usability; and 3) compare adherence to antiplatelet medications in 225 Veterans post ACS/PCI through a randomized controlled trial. Participants will be randomized to either TM, mobile app, or website-control group. The focus groups will be stratified by low/high mobile phone use and sex.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in medication adherence over 12 months	Medication Event Monitoring System (MEMS) which is an electronic pill bottle cap that captures medication taking patterns	12 months
Primary	Change in medication adherence over 12 months	Adherence to Refills and Medications Scale (ARMS)- There are two subscale scores for medication taking and medication refills. The total score is found by adding both subscales. Scores can range from 12 to 48 with 12 being completely medication adherent and 48 being completely non-adherent.	12 months
Primary	Change in medication adherence at 12 months	Medication recall questionnaire that will assess how many missed doses there were.	12 months
Primary	Change in medication adherence at 12 months	VA Corporate Data Warehouse refill data (Veteran participants)	12 months
Primary	Change in medication adherence at 12 months	Peoplechart Meds Incontext refill data (non-Veteran participants)	12 months
