Traumatic Brain Injury (TBI) Clinical Trial
— COMASCOREOfficial title:
Prediction for Coma Recovery in ICU With Comaweb: a Validation Study
The general objective of the comaScore project is to provide an external validation of the accuracy of the comaScore, a score derived from magnetic resonance imaging (MRI), to predict 1 year outcome of patients unresponsive to simple orders after traumatic brain injury (TBI), aneurysmal subarachnoid hemorrhages (aSAH) and cardiac arrest (CA) in the day 7 - day 45 period post brain injury.

Primary | The unfavorable outcome | The unfavorable outcome is defined as a Glascow Outcome Scale Extended (GOSE) of 1 to 3. This scale ranges from 1 to 8. Scores of 1 to 3 correspond to death, vegetative state, minimally conscious state or bedridden. | 1 year after the initial brain injury | |
Secondary | Time-window-specific performances of the Comascore evaluation | To assess the impact of time from brain injury to MRI allowing to calculate comaScore on the predictive accuracy of comaScore (4 periods will be determined | day 7 to 15, day 16 to 25, day 26 to 35 or day 36 to 45 | |
Secondary | Etiology-specific performances of the Comascore evaluation after cardiac arrest | " To assess the predictive accuracy of comaScore evaluated in the day 7 - day 45 period post brain injury to predict unfavorable outcome at 1-year after the first insult in patients admitted in ICU after CA or TBI or sSAH, that remain unresponsive to simple orders at least 7 days after brain injury." | 1 year after the initial brain injury | |
Secondary | Etiology-specific performances of the Comascore evaluation after traumatic brain injury | " To assess the predictive accuracy of comaScore evaluated in the day 7 - day 45 period post brain injury to predict unfavorable outcome at 1-year after the first insult in patients admitted in ICU after CA or TBI or sSAH, that remain unresponsive to simple orders at least 7 days after brain injury." | 1 year after the initial brain injury | |
Secondary | Etiology-specific performances of the Comascore evaluation after aneurysmal subarachnoid hemorrhages | " To assess the predictive accuracy of comaScore evaluated in the day 7 - day 45 period post brain injury to predict unfavorable outcome at 1-year after the first insult in patients admitted in ICU after CA or TBI or sSAH, that remain unresponsive to simple orders at least 7 days after brain injury." | 1 year after the initial brain injury | |
Secondary | Comparison between COMASCORE and OHCA score after cardiac arrest | To test the statistical difference in predictive accuracy between comaScore evaluated in the day 7 - day 45 period post brain injury and OHCA or IMPACT or WFNS score to predict unfavorable outcome at 1-year after the first insult in patients admitted in ICU after CA or TBI or aSAH, respectively, that remain unresponsive to simple orders at least 7 days after brain injury. | 1 year after the initial brain injury | |
Secondary | Comparison between COMASCORE and IMPACT score after traumatic brain injury | To test the statistical difference in predictive accuracy between comaScore evaluated in the day 7 - day 45 period post brain injury and OHCA or IMPACT or WFNS score to predict unfavorable outcome at 1-year after the first insult in patients admitted in ICU after CA or TBI or aSAH, respectively, that remain unresponsive to simple orders at least 7 days after brain injury. | 1 year after the initial brain injury | |
