Study summary

The investigators goal is to assess real-world effectiveness of patient decision aids (PtDA) for high-risk decisions using the implantable cardioverter-defibrillator (ICD) as a model.

Read the detailed description

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.

The investigators propose 3 a priori hypotheses:

  • The decision aids will have a differential effect on the decisions of participants by age (>= 70 years old vs \<70 years old);
  • The decision aids will have a differential effect on the decisions of participants by heart failure type (non-ischemic vs ischemic);
  • The decision aids will have a differential effect on the decisions of participants by the type of device they are considering (ICD vs ICD replacement vs CRT-D).

Along with these hypotheses, we recognize that other important covariates exist, such as health literacy and education level.

Study arms

  • No intervention
    Participants will fill out surveys

    These participants will fill out surveys in regard to their experiences, opinions, and knowledge of the defibrillator process.

  • Active comparator
    Educational video and/or handout

    These participants will receive an educational video and/or handout about the defibrillator process. Then they will fill out surveys in regard to their experiences, opinions, and knowledge of the defibrillator process.

    Other: Educational video and/or handout

Interventions

  • OtherEducational video and/or handout

What researchers measure

Primary outcomes

  1. Knowledge About Defibrillation at Baseline

    Multiple survey responses by participants will indicate knowledge changes over time. The Decision Quality Knowledge Survey measures knowledge about defibrillators. Possible scores range from 0 to 100, with higher scores indicating more knowledge and better outcomes.

    Time frame: Baseline

  2. Knowledge About Defibrillation at 1 Month

    Multiple survey responses by participants will indicate knowledge changes over time. The Decision Quality Knowledge Survey measures knowledge about defibrillators. Possible scores range from 0 to 100, with higher scores indicating more knowledge and better outcomes.

    Time frame: 1 month

  3. Knowledge About Defibrillation at 6 Months

    Multiple survey responses by participants will indicate knowledge changes over time. The Decision Quality Knowledge Survey measures knowledge about defibrillators. Possible scores range from 0 to 100, with higher scores indicating more knowledge and better outcomes.

    Time frame: 6 months

Secondary outcomes

  1. Reach of Eligible Patients

    Measuring how many patients of the eligible patient base are able to view or read the educational materials.

    Time frame: Baseline

Other outcomes

  1. Differential Effect by Age

    The decision aids will have a differential effect on the decisions of participants by age (\>= 70 years old vs \<70 years old)

    Time frame: Baseline, 1 month, 6 months

  2. Differential Effect by Heart Failure Type

    The decision aids will have a differential effect on the decisions of participants by heart failure type (non-ischemic vs ischemic)

    Time frame: Baseline, 1 month, 6 months

  3. Differential Effect by Type of Device

    The decision aids will have a differential effect on the decisions of participants by the type of device they are considering (ICD vs ICD replacement vs CRT-D).

    Time frame: Baseline, 1 month, 6 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2018 to primary completion in Dec 2021, 43 months.

Results were first posted in Jul 2022, 6 months after primary completion.

Of 52 non-industry interventional studies with no phase under Heart Failure, Systolic, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 46. This study's 43 months is above that.

Counting every sponsor, half of 56 studies reached it within 30 months; a quarter within 16 and three quarters within 50.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 8, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
