Official title: Addressing an Inherent Bias in Neuroprognostication: A Collaboration to Reduce the Impact of Self-fulfilling Prophecy in Cardiac ARrEst

Run by Boston Medical Center · NCT03261089 · Data updated 2026-11-12

This study is trying to find a way to better predict how well comatose patients will recover after a cardiac arrest by collecting important information about their care and outcomes.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older who are initially unconscious after experiencing a cardiac arrest from a non-perfusing rhythm.

Probably not a fit

Patients younger than 18 years or those who experienced isolated respiratory arrest without cardiac arrest will not benefit from this study.

What this trial studies

This observational study aims to develop a reliable assessment algorithm for predicting neurological outcomes in comatose patients following cardiac arrest. It will collect extensive data on demographics, cardiac arrest details, post-resuscitation care, and various prognostic assessments at standardized time points. The study will involve an international cohort, with a derivation subset for creating a prediction model and a validation subset to confirm its accuracy. Additionally, it will explore the impact of life-sustaining therapy withdrawal practices on outcome predictions.

Why it matters

Potential benefit: If successful, this study could significantly improve the ability to predict neurological outcomes in comatose cardiac arrest survivors, guiding better patient management.

How similar studies have gone: Other studies have shown promise in using multimodal prognostic assessments for similar patient populations, indicating a potential for success in this approach.
