Primary research aim

The primary objective of the study is to assess the effect of SMS messages on BP control in aboriginal people in Canada and rural Tanzania with hypertension. Secondary objectives include evaluating the efficacy of community BP measurement and SMS messaging for diagnosing hypertension in Aboriginal Canadian and rural Tanzanian people at risk of developing this health problem. A third objective is to document and explore associations between SMS messaging and community BP measurement with patient and healthcare provider satisfaction and interest in the program during the study.

Research objectives and methodology

The primary objective of the study is to assess the effect of SMS messages on BP control in aboriginal people in Canada and people in rural Moshi region in Tanzania with hypertension.

This is a prospective, randomised blinded allocation study of BP control with SMS messaging in patients with uncontrolled hypertension.

The project is being carried out in five aboriginal communities in Canada and two in Tanzania. Adult patients with uncontrolled hypertension can be enrolled into the BP control study, and those without hypertension but at high risk of developing this condition into the BP screening study if they meet the study inclusion criteria and have none of the exclusion criteria. Participants will be screened prior to enrolment and undergo a follow-up period of at least 12 months.

We have introduced and will test the efficacy of an SMS (e-voucher) model of drug access/distribution in Tanzania through private partnerships with drug distributors.

Current status

The project is enrolling patients in both countries.
