Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This cluster randomization study aims to compare the village-doctor led telemedicine integrated care versus usual care to improve compliance with the Atrial Fibrillation Better Care (ABC) pathway components and outcomes for older patients with atrial fibrillation in rural China.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

BACKGROUND Atrial fibrillation（AF) prevalence increases sharply with age, and the risk of stroke, dementia, heart failure and death increases significantly. Integrated care for atrial fibrillation patients using simple ABC pathway ('A' Avoid stroke; 'B' Better symptom management; 'C' Cardiovascular and Comorbidity optimization) is associated with a lower risk of adverse outcomes included all-cause death, composite outcome of stroke/major bleeding/cardiovascular death, and first hospitalization. In China, the prevalence of AF is high, but older people living in rural areas are more vulnerable due to low awareness and treatment gaps caused by various factors. China's rural healthcare system, which is primarily reliant on village doctors, falls short of providing optimal management for AF. To support village doctors in providing integrated care for AF, we have developed a digital health support platform. However, the role of this novel telemedicine-based integrated care for AF patients in rural China remains unclear.

AIM OF THIS STUDY This cluster randomization study aims to compare the village-doctor led telemedicine integrated care versus usual care to improve outcome of older patients with atrial fibrillation in rural China.

DESIGN The MIRACLE-AF China trial is a perspective, cluster randomization clinical trial performed in rural China. We aim to include a minimum of 1000 patients with AF aged 65 years or above from around more than 30 village clinics. Follow-up duration of this study is up to 3 years and all patients are followed up every 3 months by rural doctors. Village clinics will be randomized to either the intervention group (the village-doctor led telemedicine integrated care) or the control group (enhanced usual care).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Village doctor-led telemedicine integrated care

To empower village doctors, a new technology-based model of AF care was established in the intervention group. A digital health support platform was developed by our research team, and a network of teams consisting of village doctors and AF specialists in our research team was established in the intervention group. With the aid of this telemedicine platform, village doctors can receive more support from AF specialists in providing integrated AF care to the rural elderly with AF.

Group Type EXPERIMENTAL

Village doctor-led telemedicine integrated care

Intervention Type OTHER

1\. Reorienting the model of care: using of telemedicine platform and online consulting clinic; 2. Coordinating services: contract service by village doctor and on-line AF specialist; 3. Empowering and engaging people: provide village doctor ABC pathway training course; regular visit and drug delivery by village doctor (community support); patients and their family members education.

Enhanced usual care

Usual care plus intensified education to patients, their family members, and their village doctors.

Group Type ACTIVE_COMPARATOR
