The goal of this study is to support patients with hypertension self-management using both home blood pressure monitors and digital messaging programs. The investigators will first engage patients with technology training to use home monitors, online portal websites to view their medical record information online, and texting and mobile phone applications. Then investigators will assess the effectiveness of home blood pressure monitors and enhanced patient-clinician digital communication on blood pressure control during a 12-month intervention.

Official Title

Remote Monitoring for Equity in Advancing Control of Hypertension (REACH)


This study aims to launch an effectiveness-implementation hybrid randomized trial to adapt a multi-faceted hypertension (HTN) management program shown to work in integrated healthcare delivery systems to a safety net healthcare system, San Francisco Health Network (SFHN). In Aim 1 of this study, investigators will offer patients brief in-person training to support their use of the online patient portal and basics about text messaging. Investigators will examine pre-post training changes in technology use overall as well as by specific patient subgroups with known differences in technology uptake. In Aim 2 investigators will conduct a two-arm randomized clinical trial to assess the effectiveness of enhanced digital communication via portal messaging and texting vs. usual care on primary outcomes of blood pressure (BP) control and BP medication adherence at 12 months. In Aim 3 investigators will use a mixed methods approach to evaluate key implementation outcomes, guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework, of adapting an existing, evidence-based home BP monitoring program.
