The purpose of this study is to test the feasibility of the newly developed Trial My App platform to conduct an efficient RCT of an mHealth app that targets hypertension, a CV risk factor, without the need for in-person visits. Trial stages, including screening, consent, randomization, and collection of patient-important outcomes, will be performed virtually using the TMA platform. A combination of passive and active recruitment will begin in fall 2020 after ethics approval. A variety of recruitment materials will be distributed by a research assistant to partner newsletters, websites, community practices and primary care or speciality clinic waiting rooms. These materials include videos, paper and online posters/postcards, emails, as well as posts advertising on social media. Social media recruitment will consist of general posts and targeted ads. The primary goal at this stage is to determine whether TMA, the innovative, efficient, web-based methodology, can be used to conduct RCTs evaluating mHealth interventions. The primary feasibility outcome is study completion. Other feasibility outcomes are recruitment rate, eligibility rates, consent rates, retention rates, intervention adherence, and appropriateness of data collection processes. Descriptive analysis will be performed on the dataset using appropriate statistical methods. The secondary objective is to test the clinical efficacy of the chosen mHealth app in reducing BP in patients with sub-optimally controlled hypertension when compared with an educational control group. Efficacy outcomes include clinical assessment changes, self-management adherence, and patient-reported outcomes. This is a pilot, non-blinded, feasibility RCT, comparing use of a hypertension tracking app versus an education control in participants with hypertension that is sub optimally controlled. The investigators will later include a sub-study to validate the blood pressure data inputted into the online platform through in-person blood pressure measurements. Participants will be asked to register on the TMA site and will complete user profile and screening questionnaires and consent for participation in the pilot trial. The participants that meet inclusion criteria will be asked to electronically consent to take part in the pilot trial, and input clinical and patient-important data at 0, 1, 3, and 6 months into the web application.
