[Long-term follow-up of tracheostomized patients post severe acquired brain injury]

About 50% of patients hospitalized for severe acquired brain injury require tracheostomy, and many of them need long-term care. The main objective of this study was to describe the evolution of patients with severe acquired brain injury (sABI) tracheotomized who entered rehabilitation. Secondarily, mortality related to the success or failure of decannulation and survival at 12 months of discharge were studied.

A single-center prospective observational quantitative study. Users over 18 years of age were recruited prospectively and consecutively, tracheostomized after sABI, and admitted to a rehabilitation center between April 2018 and March 2020.

Fifty patients were included for analysis. The stay in the center was 203 (RIQ 93-320) days. At discharge to the institution, 32 (64%) patients managed to be successfully decannulated. The median number of days from admission to the center to decannulation was 49 (12-172). No decannulation failure was observed. Mortality at 12 months follow-up was 32%, five (16%) of the 32 patients who managed to be decannulated, and 11 (61%) of 18 who failed to achieve decannulation died within 12 months of follow-up. The relationship between decannulation success and mortality at 12 months of follow-up was statistically significant (p= 0.002).

Addressing the decannulation process early and properly guided is relevant as it may impact long-term survival.
