A Multicenter Trial of a Shared DECision Support Intervention for Patients Offered Implantable Cardioverter-DEfibrillators

The investigators propose the DECIDE-ICD trial: a type II effectiveness implementation hybrid
trial of the investigators ICD PtDAs. The Investigators will use a 6-site stepped-wedge
design, with implementation guided by normalization process theory® and evaluation guided by
the RE-AIM framework.

The investigators aim to evaluate reach and effectiveness of the ICD PtDAs using a pragmatic,
stepped-wedge design on decision quality (knowledge and value-concordance) and psychosocial
outcomes.

- Hypothesis 1a: PtDAs will reach over 50% of eligible patients.

- Hypothesis 1b: ICD PtDAs will be effective in improving decision quality in real-world
practice.

- Hypothesis 1c: Better informed patients will have lower anxiety, higher rates of
planning for the possibility of deactivation, and increased identification of a
surrogate decision maker.
