Clinical Trial Summary

Investigators evaluated the efficacy of a pilot-tested mHealth intervention to improving medication adherence and health outcomes among patients with coronary heart disease.

Description:

This was a two-arm parallel randomized controlled trial, in which 116 and 114 participants were assigned to the experimental and control groups, respectively. The mHealth intervention in this study had been pilot tested and tailored. Specifically, the experimental group received a medication-taking reminder every morning via WeChat app and educational materials of coronary heart disease and medication adherence every five days via Message Express app. The control group received only general educational materials, which were irrelevant to coronary heart disease or medication adherence, every 5 days via Message Express app. All participants were diagnosed with coronary heart disease. The specific recruitment criteria of participants had been published in peer-reviewed journal.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of medication non-adherence	Participants' medication non-adherence scores were measured using the Voils Medication Non-Adherence Extent Scale. Specifically, participants received the question items of the Voils Medication Non-Adherence Extent Scale every 15 days on WeChat app and provided answers	Participants' medication non-adherence scores were measured at enrollment (baseline), 15-day, 30-day, 45-day, 60-day (end of intervention), 75-day, and 90-day (end of follow-up)
Primary	Change of systolic blood pressure	Participants self-measured their systolic blood pressures every 15 days using a blood pressure cuff and reported them to investigators	At enrollment (baseline), 15-day, 30-day, 45-day, 60-day (end of intervention), 75-day, and 90-day (end of follow-up)
Primary	Change of diastolic blood pressure	Participants self-measured their diastolic blood pressures every 15 days using a blood pressure cuff and reported them to investigators	At enrollment (baseline), 15-day, 30-day, 45-day, 60-day (end of intervention), 75-day, and 90-day (end of follow-up)
Primary	Change of heart rate	Participants self-measured their heart rates every 15 days using a blood pressure cuff and reported them to investigators	At enrollment (baseline), 15-day, 30-day, 45-day, 60-day (end of intervention), 75-day, and 90-day (end of follow-up)
