Mobile Technology for Primary Stroke Prevention

Abstract

Background and Purpose— Feasibility of utilizing the Stroke Riskometer App (App) to improve stroke awareness and modify stroke risk behaviors was assessed to inform a full randomized controlled trial. Methods— A parallel, open-label, 2-arm prospective, proof-of-concept pilot randomized controlled trial. Participants were randomized to usual care/control or App intervention group and assessed at baseline, 3, and 6 months. The App measures stroke risk and provides information on management of risk factors. Participants were aged >19 years with at least 2 modifiable stroke risk factors identified, no prior stroke, and owned a smartphone. Results— Fifty participants (24 control, 26 App) were recruited from 148 eligible participants. Retention in the trial was 87%. Mean cardiovascular health (Life’s Simple 7) improved by 0.36 (95% CI, −2.10 to 1.38) in the App group compared with 0.01 (95% CI, −1.34 to 1.32) in controls ( P =0.6733). Conclusions— These findings support a full randomized controlled trial to test the effectiveness of the Stroke Riskometer for primary stroke prevention.
