The Impact of Text Messaging on Medication Adherence and Exercise Regimen Among Post-myocardial Infarction Patients

Brigham and Women's Hospital84 enrolled

Overview

The purpose of this study is to assess the impact of text message reminders on adherence to medications and exercise in patients recently discharged from the hospital after a myocardial infarction (MI).

The Impact of Text Messaging on Medication Adherence and Exercise Regimen among Post-Myocardial Infarction Patients includes two single-center randomized control trials to assess the impact of text message reminds on adherence to medications and exercise regimen in patients recently discharged from the hospital after MI. Recruitment conducted at Cambridge Cardiac Rehabilitation in Ontario, Canada for both the medication adherence and exercise trial. Potential study subjects are evaluated for inclusion and exclusion criteria, give written informed consent, and are randomized, in a 1:1 ratio, to either intervention or usual care (control). Patients randomized to the intervention arm in the medication adherence trial receive an automated text message once per day at the time they are prescribed to take their medication. The text message does not contain any personal or pharmacological information. Patients randomized to the intervention arm in the exercise adherence trial receive four text messages per day at 7:30 am, 12:00 pm, 6:00 pm, and 9:00 pm, reminding them to exercise for 30 minutes per day as per their health care provider.
