The rationale and design of reduction of uncontrolled hypertension by Remote Monitoring and Telemedicine (REMOTE) study

Abstract

Purpose: Although self-measurement of home blood pressure (HBP) is common in Japan and HBP telemonitoring via the Internet is possible, whether telemonitoring improves HBP control better than conventional practice remains unclear. Furthermore, hypertension care with online communication using telemonitored HBP is feasible, whereas the efficacy and safety of such telemedicine have not been established. We aim to compare traditional care, care with office visits using HBP telemonitoring, and antihypertensive telemedicine based on HBP telemonitoring.Methods and design: In total, 444 patients with uncontrolled hypertension will be recruited and randomly assigned to three groups: (1) control: usual care with office visits and HBP self-report, (2) telemonitoring: weekly assessment of transmitted HBP by physicians and treatment adjustment upon office visits, or (3) telemedicine: online communication instead of office visits to adjust medication using telemonitored HBP. Primary outcome is the time to control of HBP, and secondary outcomes include achieved HBP levels, adherence, treatment intensity, adverse events, patient satisfaction and cost-effectiveness.Discussion: Hypertension care with telemonitoring and telemedicine are expected to require shorter time to achieve HBP control compared to usual care. Combining HBP telemonitoring with telemedicine may lower the hurdles for starting and persisting to hypertension treatment and eventually reduce cardiovascular events.
