Tracheostomy timing in traumatic brain injury: a propensity-matched cohort study

Area of Science:

• Trauma Surgery
• Neurosurgery
• Critical Care Medicine

Background:

• The optimal timing for tracheostomy in severe traumatic brain injury (TBI) patients remains debated.
• Observational studies face confounding by indication, and interventional studies often exclude isolated TBI cases.

Purpose of the Study:

• To investigate the association between early tracheostomy (ET) and patient outcomes in isolated TBI.
• To mitigate confounding by indication using propensity score matching.

Main Methods:

• Analysis of a cohort of adult patients with isolated TBI from the American College of Surgeons' Trauma Quality Improvement Program (2009-2011).
• Classification of tracheostomy as early (≤8 days) or late (>8 days).
• Propensity score matching and sensitivity analyses including time-dependent proportional hazard regression.

Main Results:

• Early tracheostomy (ET) was associated with significantly fewer mechanical ventilation days (10 vs. 16), shorter ICU stays (13 vs. 19 days), and shorter hospital length of stay (20 vs. 27 days).
• ET correlated with reduced odds of pneumonia, deep venous thrombosis, and decubitus ulcers.
• No significant difference in pulmonary embolism or hospital mortality was observed between early and late tracheostomy groups.

Conclusions:

• Early tracheostomy in TBI patients is linked to shorter durations of mechanical ventilation, ICU, and hospital stays.
• Early tracheostomy may serve as a strategy to decrease in-hospital morbidity for TBI patients.
• Further research may explore the impact of ET on long-term outcomes.
