Pediatric tracheostomy is performed in a variety of complex, comorbid patients. Tracheostomy involves a significant burden of care for families and a risk of life-threatening complications. There is little research regarding the ideal location and protocol for safe tracheostomy decannulation. This study aims to determine patient factors that may be predictive of trial of tracheostomy decannulation being able to take place safely outside of the intensive care setting.A 10-year retrospective review of all decannulation trials at our institution is used to assess for patient factors associated with a higher risk of decannulation failure. The timing of failure and the interventions required to secure the patient's airway are reviewed. This data is used to inform recommendations regarding location of tracheostomy decannulation trial and length of inpatient stay, aiming to rationalize the use of resources while maintaining safe tracheostomy decannulation practices.One hundred and fifty-eight decannulation events occurred in 131 children over the study period, resulting in 132 successful decannulations (83.5%). Twenty-six failed episodes (16.5%) occurred in 16 patients (12.2%). Ten of these patients were successful on a second decannulation attempt and six had two or more failed decannulation attempts (4.6%). Failed decannulation was higher in patients with upper airway obstruction as the indication for tracheostomy (20.3% failure rate versus 0%). History of prematurity was significantly associated with failure of decannulation. Nine decannulation failures occurred immediately, with a further 9 failures occurring within the first 24 hours. A further 3 failures occurred in hospital and 5 following discharge. No mortality or significant morbidity occurred during any decannulation trial.Our study identified a higher rate of decannulation failure in patients with upper airway obstruction, suggesting that decannulation trials for this subgroup should occur in the intensive care unit. Patients with tracheostomy for other indications may be safe to decannulate in a ward setting. Early failures demonstrated more rapid deterioration. Further research is recommended on the utilization of capping trials or polysomnography prior to decannulation to help guide the ideal location and timing for trial decannulation.
