The trial aims to investigate the efficacy of a comprehensive digital intervention for hypertension treatment in cluster clinics. 40 PHC centers will be selected from different areas in China, and eligible patients being screened consecutively in each site, then all PHC centers will be randomized into intervention group and control group. The physicians and patients from the 20 intervention sites will receive training and support on the use of the CHESS system, and the control group will continue to receive usual care. The multi-faceted CHESS intervention includes: (1) home blood pressure monitoring (HBPM) for patients, and the data will be uploaded to central electronic health records (EHR) automatically; (2) a Smart Reminder and Alert System (SRAS) to send educational messages and reminders to support patients on HBPM, improve blood pressure medication adherence and lifestyle modification; (3) a decision support system (DSS) to provide physicians with antihypertensive medications prescriptions and referral recommendations; (4) regular quality assessment reports will be provided to health care providers automatically to improve the quality of hypertension management at PHC level. All participants will be asked to attend the clinic at least once every 3 months, and be followed up for 12 months.
This cluster randomized controlled trial aims to evaluate the efficacy of a comprehensive intelligent hypertension management system (CHESS) in blood pressure lowering in primary health care (PHC) settings of China.
