Severe traumatic brain injury (TBI) is a major cause of hospitalizations and deaths around the world, affecting more than five million people each year. Predicting outcomes following a brain injury can be challenging, yet families are asked to make decisions about continuing or withdrawing life-sustaining treatment within days of injury.
In a new study, Mass General Brigham investigators analyzed potential clinical outcomes for TBI patients enrolled in the Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) study for whom life support was withdrawn. The investigators found that some patients for whom life support was withdrawn may have survived and recovered some level of independence a few months after injury. These findings suggest that delaying decisions on withdrawing life support might be beneficial for some patients.
Families are often asked to make decisions to withdraw life support measures, such as mechanical breathing, within 72 hours of a brain injury. Information relayed by physicians suggesting a poor neurologic prognosis is the most common reason families opt for withdrawing life support measures. However, there are currently no medical guidelines or precise algorithms that determine which patients with severe TBI are likely to recover.
