Safety of percutaneous dilatational tracheostomy performed by intensivists versus surgeons: A retrospective cohort study.

Background: Percutaneous dilatational tracheostomy (PDT) is the preferred method for managing critically ill patients requiring prolonged mechanical ventilation. We aimed to compare the safety of PDT performed by intensivists versus surgeons.

Methods: This retrospective, single center, cohort study included all the patients who underwent PDT from 2014 to 2023. Propensity score matching was performed to adjust the imbalances of covariates between the groups. The primary outcome was the occurrence of early complications after PDT. Secondary outcomes were the development of late complications of PDT and mortality directly related to tracheostomy.

Results: 1685 consecutive patients with critical illness were included in the analysis. Of these, 1396 (82.8%) PDTs were performed by surgeons and 289 (17.2%) by intensivists with background residency training in internal medicine. Early complications were reported in 80 (5.7%) of the patients in the surgeon group and in 13 (4.5%) patients in the intensivist group (p = 0.40). Minor hemorrhage was the most common early complication. Secondary outcomes were comparable in both groups. In a propensity score-matched cohort, the findings remained consistent.

Conclusions: This study suggests that PDT can be performed by intensivists, as well as surgeons, with the same safety profile. Our findings underscore the importance of incorporating PDT into the intensive care unit (ICU) training syllabus, ensuring the procedure is readily accessible with reliance on the expertise of ICU staff.
