Mobile Health Technology to Improve Care for Patients With Atrial Fibrillation
Key result
Mobile health-supported integrated care cuts stroke, death, and rehospitalization by ~61% versus usual care.
- HR 0.39
- 95% CI 0.22 to 0.67
- P<0.001
- n=3,324
Why the study?
Current AF management is limited by low detection, non-adherence to guidelines, and lack of consideration of patient preferences, highlighting the need for a holistic, integrated approach.
Does a mobile health technology-supported AF integrated management strategy reduce stroke/thromboembolism, all-cause death, and rehospitalization in patients with atrial fibrillation?

“using a simple care pathway, such as the ABC pathway, but in a holistic or integrated care manner, will improve the management, and therefore outcomes, of patients with AF”
RTRitu TrivediPostdoctoral researcher, University of Sydney
“It is a pivotal study, that successfully implemented a digitally enabled integrated care program for ~1600 patients with atrial fibrillation across many centres in China and found improvements in health outcomes, hospitalisation rates, patient-reported outcomes and was found to be cost-effective. A key challenge with digital health is implementation and the methodologies that were used to achieve these outcomes in this work are commendable.”
“Our study clearly highlights the need for an integrated care approach to holistic AF care, supported by mobile health technology”
Implication
A mobile health application incorporating the ABC pathway for atrial fibrillation management significantly reduces the composite of stroke, death, and rehospitalization compared to usual care.
Key Points
- To determine whether a mobile health (mHealth) technology-supported integrated management strategy reduces adverse clinical events in patients with atrial fibrillation compared with usual care.
- Cluster randomized trial across 40 cities in China enrolling adult patients with atrial fibrillation from June 1, 2018, to August 16, 2019 (ChiCTR-OOC-17014138).
- Allocated 1,646 patients (mean age 67.0 years, 38.0% female, mean follow-up 262 days) to integrated care using a mobile AF Application (mAFA) implementing the ABC Pathway, and 1,678 patients (mean age 70.0 years, 38.0% female, mean follow-up 291 days) to usual care.
- Evaluated the primary composite endpoint of ischemic stroke/systemic thromboembolism, all-cause death, and rehospitalization using Cox proportional hazard modeling adjusted for baseline risk.
- The primary composite outcome occurred in 1.9% of the mAFA group versus 6.0% of the usual care group (HR: 0.39; 95% CI: 0.22 to 0.67; p < 0.001).
- Rehospitalization rates alone were significantly reduced with the mAFA intervention compared with usual care (1.2% vs. 4.5%; HR: 0.32; 95% CI: 0.17 to 0.60; p < 0.001).

Guo et al. (2020) conducted an RCT in Atrial fibrillation (n=3,324). Mobile AF Application (mAFA) incorporating the ABC Pathway vs. Usual care was evaluated on Composite of ischemic stroke/systemic thromboembolism, death, and rehospitalization (HR 0.39, 95% CI 0.22 to 0.67, p=<0.001). A mobile health-supported integrated care strategy reduced the composite of stroke, death, and rehospitalization compared with usual care (1.9% vs 6.0%; HR 0.39; 95% CI 0.22-0.67; p<0.001).
