Tracheostomy practice and timing in traumatic brain-injured patients : a CENTER-TBI study

• PURPOSE: Indications and optimal timing for tracheostomy in traumatic brain-injured (TBI) patients are uncertain. This study aims to describe the patients' characteristics, timing, and factors related to the decision to perform a tracheostomy and differences in strategies among different countries and assess the effect of the timing of tracheostomy on patients' outcomes.METHODS: We selected TBI patients from CENTER-TBI, a prospective observational longitudinal cohort study, with an intensive care unit stay ≥ 72 h. Tracheostomy was defined as early (≤ 7 days from admission) or late (> 7 days). We used a Cox regression model to identify critical factors that affected the timing of tracheostomy. The outcome was assessed at 6 months using the extended Glasgow Outcome Score.RESULTS: Of the 1358 included patients, 433 (31.8%) had a tracheostomy. Age (hazard rate, HR = 1.04, 95% CI = 1.01-1.07, p = 0.003), Glasgow coma scale ≤ 8 (HR = 1.70, 95% CI = 1.22-2.36 at 7; p < 0.001), thoracic trauma (HR = 1.24, 95% CI = 1.01-1.52, p = 0.020), hypoxemia (HR = 1.37, 95% CI = 1.05-1.79, p = 0.048), unreactive pupil (HR = 1.76, 95% CI = 1.27-2.45 at 7; p < 0.001) were predictors for tracheostomy. Considerable heterogeneity among countries was found in tracheostomy frequency (7.9-50.2%) and timing (early 0-17.6%). Patients with a late tracheostomy were more likely to have a worse neurological outcome, i.e., mortality and poor neurological sequels (OR = 1.69, 95% CI = 1.07-2.67, p = 0.018), and longer length of stay (LOS) (38.5 vs. 49.4 days, p = 0.003).CONCLUSIONS: Tracheostomy after TBI is routinely performed in severe neurological damaged patients. Early tracheostomy is associated with a better neurological outcome and reduced LOS, but the causality of this relationship remains unproven.
