TRAjectories and CLinical ExpeRiences of ICD Therapy Study

United States500 participantsStarted 2021-12-15

Plain-language summary

This is a prospective cohort study of older patients receiving implantable cardioverter-defibrillators. The purpose of the TRACER-ICD study is to conduct a prospective cohort investigation with the goal of 500 patients age \>65 receiving new primary prevention implantable cardioverter-defibrillators (ICDs). Patients will be followed quarterly for 18 months with interviews, electronic record review, and remote monitoring to characterize clinical and functional trajectories following device implantation, with permission for extended electronic follow-up for up to 10 years (Aim 1). This cohort will support validation and refinement of an established model for predicting personalized outcome profiles for ICD therapies and death (Aim 2). Lastly, we will combine electronic record review with semi-structured interviews with patients and physicians to evaluate physician and patient experiences with a prototype individualized shared decision-making (SDM) tool (Aim 3).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
