[A survey on clinical practice of tracheostomy decannulation in medical institutions at all levels across the country].

Objective: A questionnaire survey was conducted on the clinical practice of tracheostomy decannulation among medical staff in medical institutions at all levels across the country. Methods: The questionnaire was determined by literature review and expert consultation to investigate the clinical practice of tracheostomy decannulation among medical staff in comprehensive and rehabilitation hospitals of different levels across the country and the factors considered when deciding to decannulate. Statistical methods used χ² test and one-way ANOVA. Results: A total of 570 questionnaires were collected from all over the country, with 463 valid questionnaires. The survey results showed that the most important factors in clinical practice to determine the decannulation of the tracheostomy tube were upper airway patency, cough effectiveness, level of consciousness and oxygenation. Before decannulation, 220 (47.50%) would choose to change to metal cannula, and 384 (82.90%) would routinely occlude the tube. 294 (63.50%) thought that re-intubation within 24 hours after decannulation of the tracheostomy tube was failure of decannulation. The decannulation failure rate was mostly 2%-5%. Conclusions: Upper airway patency, cough effectiveness, level of consciousness and oxygenation were important factors when considering decannulation. Reintubation within 24 hours of decannulation was defined as failure by the majority of respondents.
