A mHealth-based care model for improving hypertension control in stroke survivors: Pilot RCT.


ABSTRACT: PURPOSE:Hypertension (HTN) is significantly under-treated in stroke survivors. We examined usability and efficacy of a mHealth -based care model for improving post-stroke HTN control (Funding: AHRQ R21HS021794). METHODS:We used a RCT design. Planned study duration was 90?days. Intervention arm (IA) participants measured their BP daily using a smart phone and wireless BP monitor. This was transmitted automatically to the study database. Investigators (Physician?+?PharmD) made bi-weekly medication adjustments to achieve the BP goal. Control arm (CA) participants received a digital BP monitor and usual care. We examined Usability (measured with Marshfield System Usability Survey) and HTN control efficacy using an ITT (intent-to-treat) and as-treated (AT) analyses. RESULTS:Fifty participants (IA?=?28; CA?=?22) completed the study. The Marshfield survey question, "I thought the system was easy to use" mean score was 4.6, (5?=?strongly agree). Mean SBP declined significantly between enrollment and study completion in the IA. In ITT, IA SBP declined 9.88?mm, p?=?0.005. In AT, IA SBP declined 10.81?mm, p?=?0.0036. CA SBP decline was 5-6?mm?Hg (not significant). In the ITT, baseline HTN control (SBP?
