“…Practice of tracheostomy is difficult to compare to other cohorts of invasively ventilated COVID–19 patients because of the large variability seen in both incidence and timing in a number of identified studies. Incidence of tracheostomy in invasively ventilated COVID–19 patients has been shown to range from 8 to 77% 4 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , and mean or median timing from 4 to 23 days 6 , 20 , 23 , 25 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 . As many of these identified studies are single center, this may reflect differences in local practices irrespective of national guidelines.…”
