ABSTRACT
Background: Patients with coronavirus disease 2019 (COVID-19) pneumonitis may progress to acute respiratory distress syndrome (ARDS) requiring endotracheal intubation and prolonged mechanical ventilation (MV). There are limited data on the optimum time of tracheostomy in COVID-19 patients progressing to ARDS. Methods: This was a retrospective observational study of all patients diagnosed with COVID-19 who progressed to ARDS requiring MV and undergone tracheostomy. We aimed to conduct a study to observe the impact of tracheostomy on the mortality of these patients and the impact of timing of tracheostomy on outcomes in these patients. Results: Of the total 162 patients, 128 (79%) were male and 34 (21%) were female. Early group (≤14 days) comprised 37 patients, while 125 patients were included in late group (>14 days). A total of 91 (56%) patients died at the end of this period. Among the patients who died, 21were included in the early group, while the late group comprised the remaining 70 patients. On comparing the patients who died, the duration of stay in the intensive care unit (ICU) was significantly different in the two groups (median [Q1-Q3]: 12 [11-13] vs. 23 [19-28] days, P < 0.001). The number of days to death also differed significantly between the two groups (median [Q1-Q3]: 28 [21-38] vs. 24 [14-30] days, P = 0.009). Conclusion: Early tracheostomy is associated with significantly shorter length of ICU stay in COVID-19 patients that have progressed to ARDS. However, the timing of tracheostomy had no influence on the overall mortality rate in these patients.
