Introduction: The DreamGlobal study incorporates mobile health innovations in technology with SMS text messaging and task shifting of blood pressure measurement. Methods: In this pragmatic RCT study participants with uncontrolled hypertension on or off of medication, received culturally competent text messages over a one year period. All participants lived on First Nations reserves in remote and rural parts of Canada. Initial blood pressure screening was with an automated oscillometric device. Community Health Workers and nurses were trained to measure blood pressure with an approved oscillometric device which was Bluetooth enabled. Once participants were registered online, they received their blood pressure results on their own mobile phone as a text message and guidelines based text messages. Their primary health care provider also received the results as a fax. They were randomized to receive health behaviour change messages alone or active messages including a recommendation to see their health care provider if their blood pressure was above target. The baseline blood pressure was the mean of all readings in the first two months and the final blood pressure, the mean of the last two months. The main outcomes were change in blood pressure between the two groups (active or passive text messages) and the proportion achieving control. Results: One hundred twenty-seven subjects had hypertension. Blood pressure in the first two months of measurement was 143/85 mmHg over all. The blood pressure in the final two months of the study will be reported as will the change in blood pressure in both the active and passive text message groups and the proportion achieving blood pressure control in each group. Health literacy regarding the guideline’s based text messages was measured to determine if there was a difference between scores for the passive messages (all participants) and the active messages (active group only). Discussion: Achieving guidelines based management of hypertension is more challenging in remote, ...
