HEMOglobin Transfusion Threshold in Traumatic Brain Injury OptimizatioN: The HEMOTION Trial (HEMOTION)

May 1, 2024 updated by: Dr Alexis Turgeon, CHU de Quebec-Universite Laval
Most trauma deaths are related to traumatic brain injury (TBI). Although the management of patients has improved, mortality remains unacceptably high, and half of survivors of moderate and severe TBI are left with major functional impairment. Current management guidelines are based on limited evidence and practice is highly variable. Most acutely ill patients with TBI will develop anemia, which may decrease oxygen delivery to a fragile brain. While clinical practice is moving towards transfusing at low hemoglobin (Hb) levels, experts have expressed concerns regarding restrictive strategies, which may adversely affect clinical outcomes in TBI. Our primary objective is to evaluate the effect of red blood cell (RBC) transfusion thresholds on neurological functional outcome. We hypothesize that a liberal transfusion strategy improves outcomes compared to a restrictive strategy.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
