Effect of Smartphone Application (MED-AD) on Medication Adherence Among Patients With Cardiovascular Disease in Oman

Effect of Smartphone Application (MED-AD) on Medication Adherence Among Patients With Cardiovascular Disease in Oman: A Multicenter Randomized Clinical Trial

This study aims to:

1. Investigate the impact of MED-AD intervention on medication adherence among CVD patients, compared to patients receiving text message reminders or routine care alone at baseline, 6 months, and 12 months later.
2. Evaluate the effectiveness of MED-AD intervention on clinical outcomes among patients with CVD, compared to the outcomes of patients receiving text or routine care alone at baseline, 6 months, and 12 months later.

This study is a prospective randomized controlled clinical trial (RCT) with three arms:

1. MED-AD intervention: MED-AD is a smartphone application that will use the following strategies (pill reminders, Medication Adherence Report, medication intake confirmation, Medical Appointment Reminder, and educational notifications) to enhance medication adherence
2. Text message reminders: Participants will receive short text message (SMS) reminders to remind them to take medications as prescribed once daily
3. Routine care only: Participants will receive routine care that does not include text messages or reminders and education through an application.

Inclusion Criteria:

1. diagnosed with at least one CVD (i.e., HTN, IHD, hyperlipidemia),
2. prescribed at least one medication for at least one year,
3. Omanis aged 18 years or older,
4. registered in the selected healthcare center, and 5) agreed to participate in the study
