Gedetailleerde beschrijving
Adherence to treatment is disappointingly low among patients with chronic health disorders especially after 6 month of initiating drug therapy. In hypertensive patients , as reported by WHO, 50% of non-adherence could be expected. Poor adherence to anti hypertensive medications results in increased morbidity, mortality and costs. One of the reasons that could implicate medications adherence can be attributed to seeing no physical sign of better controlling blood pressure. Self monitoring of blood pressure at home has been reported to improve patients adherence to their medications.
This study is a 2-arm randomized controlled trial. The investigators aim to evaluate the effect of home-based blood pressure measurement with an electronic device on medication adherence and blood pressure status.
One hundred ninety six hypertensive patients aged at least 18 years old are recruited in an ambulatory care setting and are evenly allocated to the study arms with balanced-block telephone randomization.
Appropriate medication is prescribed as preferred by the cardiologist (single daily dose medicines are recommended). Patients in both arms are followed for 24 weeks, each will be visited by the cardiologist four times during the study period. In each visit, patients' blood pressure will be measured twice by a nurse in the office.
In the intervention arm, electronic blood pressure device is provided for each patient and he/she will be trained to measure blood pressure at home once daily (same time each day). A logbook is also provided to document the daily blood pressure level.
Primary outcome of the study is the blood pressure measured at each office visit overtime. Medication adherence is measured by pill count method as the secondary outcome.

Pill count method is employed.
At the time of each office visit, patients bring their medications with themselves and the researcher counts the unused pills.
Adherence is calculated as percentage of the pills used during previous weeks.
