Accelerating Access and Improving Imaging in Heart Failure Care (A2I2HF) Pilot Study
연구 개요
상세 설명
Heart failure remains underdiagnosed in frontline care settings, in part due to limited access to timely echocardiography. Recent advances in artificial intelligence (AI)-assisted echocardiography may facilitate scalable bedside screening through automated image acquisition support and interpretation.
This is a prospective, multicenter, cluster randomised trial which will assess the feasibility and acceptability of routine implementation of AI-assisted point of care echocardiography on HF detection and downstream processes of care for patients with suspected HF being discharged from the Emergency Department.
This study will be carried out at 2 participating Emergency Departments (EDs) in Alberta, Canada. Each ED site will alternate monthly between Intervention (AI-assisted echocardiography) and Control (Usual Care) periods.
During intervention periods, patients with suspected HF will undergo AI-assisted echocardiography using a handheld point of care EchoNous Kosmos device by the treating ED physician. The US2.ai algorithm will generate an AI-automated echo report. During control periods, patients will be managed according to usual care.

실험적: Intervention
During each month-long Intervention period, an AI-assisted POCUS tool will be available for ED physicians use, at their discretion, to assess left ventricular ejection fraction (LVEF) and diastolic function in patients presenting to the ED with suspected HF.
The AI-automated echocardiogram report may be used in the referral pathway to the HF clinic if deemed clinically appropriate.
|
ED physicians at both sites will be provided with 1 session of in person training in the use of the AI-assisted POCUS device within 4 weeks of randomization including,

간섭 없음: Control Period (Usual Care)
During each month-long Control period, the ED physicians will manage patients as close to "true" usual care as possible.
There is no "placebo" arm.
No actions will be undertaken to impede or prohibit care in the usual care arm.
