Cardiovascular Risk Assessment and Dynamic Monitoring-based Prevention Trial (CRITICALLY)

Cardiovascular Risk Assessment and dynamIc Monitoring-based Prevention Trial for prImary Care quALity evaLuation in Yinzhou

The CRITICALLY study is a cluster randomized trial that will evaluate the effectiveness of a risk-based dynamic monitoring strategy for the primary prevention of cardiovascular high-risk Chinese adults.

Study Overview

• Status: Recruiting
• Conditions: Cardiovascular Diseases
• Intervention / Treatment: Other: Frequent and automatic cardiovascular risk assessment; Other: Dynamic risk monitoring; Other: Regular GP visits

Detailed Description

The objective of the study is to evaluate the effectiveness of a risk-based management strategy on cardiovascular risk scores (calculated by the 2019 WHO cardiovascular risk charts) in 24 months (Phase I) and the incidence of major adverse cardiovascular events in 60 months (Phase II). Totally 216 clinics in Yinzhou District, China will be randomized to the intervention or the control arms with usual care. The interventions supported by the web-based decision support system include (1) cardiovascular risk assessment, (2) dynamic risk monitoring, and (3) regular visits by the general practitioner every three months. Only usual care will be provided in the control arm. The primary outcome is the change in cardiovascular risk scores for Phase I and the incidence of the composite endpoint of coronary heart disease, stroke, heart failure and all-cause mortality for Phase II. If the comprehensive strategy is proven effective, it could provide evidence for the primary prevention of cardiovascular diseases using digital health technology.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Intervention arm; The interventions include cardiovascular risk assessment, dynamic risk monitoring, and regular general practitioner (GP) visits. The frequency of risk assessment, risk monitoring, and automatic mobile texting will be once per month, while regular GP visits will be once per three months.	Other: Frequent and automatic cardiovascular risk assessment; The 10-year cardiovascular risk scores using the 2019 World Health Organization (WHO) laboratory-based risk charts will be automatically calculated using the latest health information on an EHR-based system per month.; Other: Dynamic risk monitoring; High-risk individuals will be reassessed by the Dynamic Risk-based Early wArning and Monitoring (DREAM) system to obtain the short-term risk. The DREAM system will send a text message about advice to the high-risk individual every month. The text message includes information on the health status (e.g., current cardiovascular risk, level of blood pressure and lipid) and real-time warning messages (e.g., high short-term risk).; Other: Regular GP visits; The general practitioners will communicate with the participants based on the information automatically generated from the DREAM system every three months: each participant's cardiovascular risk score, health status (e.g., diabetes mellitus and/or hypertension), and Chinese guidelines-based recommendations (e.g., "for the management of dyslipidemia, to provide clear treatment targets for high-risk participants").
No Intervention: Control arm; Current regular management (usual care) will be kept in the control arm. The management objectives are for patients with hypertension or diabetes mellitus. The frequency of follow-up is at least once per three months.
