Decision Support Among Surrogate Decision Makers of the Chronically Critically Ill (INVOLVE) (INVOLVE)
A Clinical Trial of Decision Support for End of Life Care Among Surrogate Decision Makers of the Chronically Critically Ill
Each year, millions of Americans are admitted to an intensive care unit (ICU). For more than half of them, ICU admission initiates a cascade of decisions about treatment and end-of-life care.This is particularly the case for patients with chronic critical illness, a life-limiting syndrome. Most (74%-82%) ICU patients who require mechanical ventilation have transient or persistent cognitive impairment that precludes them from making their own healthcare decisions. Among ICU patients, the chronically critically ill (CCI) are at highest risk for cognitive impairment and thus require a surrogate decision maker (SDM), usually a family member. SDMs for the critically ill often describe high states of psychological stress associated with the uncertainty of the patient's condition and their decision making role.
The purpose of this study is to test the effectiveness of two decision support interventions for end-of-life care delivered to SDMs of CCI patients. This will be the first study to test interventions tailored to the unique needs of the SDMs of CCI patients delivered using an interactive avatar based format.
調査の概要
詳細な説明
The investigators will conduct a three-arm unblinded clinical trial using pre- and post-tests to evaluate the efficacy of two electronic decision-support interventions, Interactive Virtual Decision Support for End-of-Life and Palliative Care (INVOLVE) and Informational Support (IS), compared to each other and to usual care (UC) among 270 SDMs of cognitively impaired CCI patients. This design will allow the investigators to prospectively compare the efficacy of the experiential avatar-based decision support tool (INVOLVE) with both an information-only condition and UC. Subjects assigned to an experimental condition (INVOLVE or IS) will receive two doses of the intervention, at enrollment and 1 day later. After the second dose, these subjects will have access to their assigned condition for subsequent self-administered doses, which will be electronically captured until the patient's ICU discharge or death. Data will be collected at (T1) baseline (Day 3 or 4 of the patient's ICU stay), and then on Days 1, 3, 7 and 90 post-baseline
.
The investigators aim to:
- Identify the essential elements of the graphical user interface and educational content needed to revise the INVOLVE prototype for a set of common end-of-life decisions that occur in the ICU.
- Evaluate if there are differences in the decision making readiness and decision making quality between subjects exposed to INVOLVE, IS, or UC on Days 1, 3, and 7 days post-baseline while accounting for covariates (prior SDM experience, SDM knowledge of the patient's preferences, and SDM's religious beliefs).
- Determine if there are differences in the post-decision outcomes of SDMs and their CCI patient by study condition while accounting for covariates at 90 days post-baseline.

介入・治療 |
|---|---|
|
実験的：INVOLVE
The first study condition, called "Interactive Virtual Decision Support for End-of-Life and Palliative Care (INVOLVE)" will consist of exposures to an avatar-based decision support technology that will be administered via tablet computer and allow SDMs opportunities to practice their communication and decision making skills through interactions with avatars that portray a decision coach and various healthcare providers.
|
Interactive content and decision coaching with tailored framing of messages to subject's informational processing style and stage of change to promote participatory decision making behavior.
Consideration of options, consequences, values, and preferences to formulate an informed decision.
|
|
実験的：Informational Support
The second condition, called Informational Support (IS), will also be administered via tablet computers and expose SDMs to educational resources of INVOLVE without the experiential components.
|
Passive, non-tailored informational support.
Screen-based education (videos) with information content on advance care decisions that occur in the intensive care unit.
|
|
実験的：Usual Care
The third condition, usual care (UC), will expose SDMs to the routine communication and decisional support practices provided by the healthcare team.
|
Routine decision support practices by the healthcare team.
Family meetings, bedside updates, and access to printed or electronic decision aids.
