Summary

Objective: To test the primary hypothesis that SMS text messages delivered to patients via mobile phone can improve blood pressure within 12 weeks compared to usual care

Design: Parallel group, randomized, controlled trial; the patient is the unit of randomization

Setting: General Medicine Outpatient Continuity Clinic of the Philippine General Hospital and Private Outpatient Clinics near the Philippine General Hospital

Patients: Ambulatory men and women aged 19 years and older (N=700) with a diagnosis of essential hypertension, on maintenance blood pressure-lowering medications, who have daily access to a mobile phone in the household and know or live with someone who knows how to retrieve, read and reply to text messages using a mobile phone

Intervention: SMS text messages delivered twice a week for 12 weeks, which aim to 1) provide information regarding hypertension; 2) remind patients to take their medications.

Main Outcome Measure: The primary outcomes are the mean change in systolic and diastolic blood pressures at the end of 12 weeks. The secondary outcomes are improvement in blood pressure control rate and medication adherence.

Interventions

OTHER

SMS text reminders

Patients in the intervention arm will receive 2 text messages per week delivered via SMS on randomly chosen days and times during the 12-week study period. The aims of the messages are to remind patients to take their blood pressure medications daily, what the target blood pressure is, and the benefits of daily intake of anti-hypertensive medications.

OTHER

Usual Care

Patients in the usual care arm will receive the care usually provided by their physicians. This consists of consultations, medical advice, and prescriptions for maintenance medications. They will not be sent any SMS text reminders from the study.
