Abstract
BACKGROUND AND OBJECTIVES: We compared decannulation-related factors between COVID-19 and non-COVID-19 patients who underwent tracheostomy. SUBJECTS AND METHODS: We conducted a retrospective study of patients who underwent a tracheostomy. The clinical factors were compared between the successful (decannulation within 3 months) and failed decannulation (decannulation over 3 months) groups in COVID-19 and non-COVID-19 patients. RESULTS: The successful decannulation rates were 41.1% in COVID-19 and 45.1% in non-COVID-19 patients, with no significant differences in demographic and clinical factors between the two groups. In the non-COVID-19 patients, the failed decannulation group had a higher proportion of cerebrovascular and pulmonary diseases. Ventilator dependency or increased oxygen demand was the primary cause of decannulation failure in both groups, with no significant differences except for a higher prevalence of swallowing problems in the COVID-19 group (42.4% vs. 20.0%). CONCLUSIONS: The predominant cause of decannulation failure was ventilator and oxygen demand in both the non-COVID-19 and COVID-19 patients. In the non-COVID-19 patients, underlying cerebrovascular diseases were considered to have a significant impact on the decannulation process. On the other hand, swallowing problems significantly influenced decannulation among the COVID-19 patients. Therefore, we should consider early and active respiratory and swallowing rehabilitation to facilitate successful decannulation in COVID-19 patients.
