Surgical Versus Dilational Tracheostomy in Patients with Severe Stroke: A SETPOINT2 Post hoc Analysis

Tracheostomy in mechanically ventilated patients with severe stroke can be performed surgically or dilationally. Prospective data comparing both methods in patients with stroke are scarce. The randomized Stroke-Related Early Tracheostomy vs Prolonged Orotracheal Intubation in Neurocritical Care Trial2 (SETPOINT2) assigned 382 mechanically ventilated patients with stroke to early tracheostomy versus extubation or standard tracheostomy. Surgical tracheostomy (ST) was performed in 41 of 307 SETPOINT2 patients, and the majority received dilational tracheostomy (DT). We aimed to compare ST and DT in these patients with patients. All SETPOINT2 patients with ST were compared with a control group of patients with stroke undergoing DT (1:2), selected by propensity score matching that included the factors stroke type, SETPOINT2 randomization group, Stroke Early Tracheostomy score, patient age, and premorbid functional status. Successful decannulation was the primary outcome, and secondary outcome parameters included functional outcome at 6 months and adverse events attributable to tracheostomy. Potential predictors of decannulation were evaluated by regression analysis. Baseline characteristics were comparable in the two groups of patients with stroke undergoing ST (n = 41) and matched patients with stroke undergoing DT (n = 82). Tracheostomy was performed significantly later in the ST group than in the DT group (median 9 [interquartile range IQR 5–12] vs. 9 [IQR 4–11] days after intubation, p = 0.025). Patients with ST were mechanically ventilated longer (median 19 [IQR 17–24] vs.14 [IQR 11–19] days, p = 0.008) and stayed in the intensive care unit longer (median 23 [IQR 16–27] vs. 17 [IQR 13–24] days, p = 0.047), compared with patients with DT. The intrahospital infection rate was significantly higher in the ST group compared to the DT group (14.6
