PMID 38888736WHAT IT FOUND
Patients with severe brain injury who had tracheostomies survived as long as those without, but remained heavily disabled.
Younger age predicted better survival and walking ability, yet most patients could not walk or eat by mouth after discharge.
Key findings
01Survival rates were similar between patients with traumatic and non-traumatic brain injuries, with no significant difference in long-term survival.
02Younger age was significantly associated with a higher probability of regaining the ability to walk, successful decannulation, and oral intake.
03Most patients remained immobile and dependent on gastrostomy feeding after discharge from the intensive care unit.

What it does not show
The study is retrospective, meaning data was collected after the fact, which can introduce bias and limits the quality of outcome assessments. The study did not evaluate cognitive function or subjective quality of life, which are major factors in long-term disability and rehabilitation planning. Follow-up was limited to five years, which may not capture delayed functional recovery or long-term survival trends. The use of the Barthel Index may have a floor effect in this severely impaired population, potentially masking subtle differences in functional status.
Declared interests
The authors declared no conflicts of interest. The study was funded by a grant from the Military University Hospital (MO1012).
The easy way to misread this
Do not interpret the lack of survival difference between traumatic and non-traumatic groups as evidence that the cause of injury does not affect functional outcomes. The study found that most patients in both groups remained heavily disabled, and younger age, rather than injury type, was the primary predictor of regaining basic functions like walking.
