A digital tool to help decide about an ICD

Official title: Digital Shared Decision-Making Aid to Improve Patient-Centered Outcomes in Implantable Cardioverter-Defibrillator (ICD) Decisions Among Older Patients, ENHANCE-ICD (SU sIRB)

Run by Stanford University · NCT07913204 · Data updated 2026-11-12

We’re testing a patient-friendly online aid to help people with advanced heart failure decide whether an implantable cardioverter-defibrillator (ICD) is right for them.

Is this trial a fit for you?

Likely a good fit

Adults aged 70 or older with primary-prevention ICD criteria, English/Mandarin/Spanish speakers, and a diagnosis of Class II-III heart failure with LVEF ≤ 35%.

Probably not a fit

Patients with a history of ICD implantation for secondary prevention or those not meeting primary-prevention criteria may not benefit from the tool.

What this trial studies

This project develops a digital decision aid for heart failure patients considering an ICD. It uses surveys, focus groups, and interviews to gather background information and refine the tool. The digital aid will be tested in a randomized trial against usual care to see if it helps patients make more informed choices about ICD placement.

Why it matters

Potential benefit: If successful, the tool could help patients better understand risks and benefits of ICDs and make choices aligned with their values.

How similar studies have gone: Previous work in shared decision-making and patient education suggests digital aids can support informed choices, though this exact approach is being evaluated in a novel ICD context.
