Revisiting the Great Ormond Street Hospital protocol for ward decannulation of children with tracheostomy

Abstract

IntroductionTracheostomy decannulation is an important and final step in managing patients once the underlying issue requiring a tracheostomy resolves. However, no consensus exists on the optimal method to decannulate a paediatric patient. We revisit the Great Ormond Street Hospital (GOSH) tracheostomy decannulation protocol, a 5-day process involving downsizing the tracheostomy tube, capping, and observation, to evaluate its effectiveness and assess if changes to the protocol are required. MethodThis is a retrospective study, reviewing patient records between April 2018 and April 2023 from a single quaternary care centre. Data extracted include comorbidities, age at the time of decannulation, duration of tracheostomy, reason for tracheostomy insertion, whether a decannulation attempt was successful or not, and the timings of decannulation failure. Results66 patients that met the selection criteria underwent a decannulation trial between April 2018 and April 2023. 32 patients were male, and 34 patients were female. Age at attempted decannulations ranged from 1 year to 18 years, with an average age of 6.1 years.There were a total of 93 attempts at decannulation, with 51 (54.8%) successful attempts, 35 (56.5%) first decannulation attempt successes, and 42 (45.2%) unsuccessful attempts. 17 patients had 2 attempts at decannulation, and 4 patients had 3 or more attempts at decannulation. Of the unsuccessful attempts, patients mostly failed on capping of the tracheostomy tube with 33 failures (35.5%). ConclusionThe GOSH protocol achieved similar success rates to comparable protocols. The protocol's multi-step approach provides thorough evaluation and support for patients during the decannulation process, and its success on a complex patient cohort supports its continued use.
