Complications of surgical and percutaneous tracheostomies, and factors leading to decannulation success in a unique Middle Eastern population.

introductionSurgical and percutaneous tracheostomy remains a commonly performed procedure in the intensive care unit (ICU). Given the unique patient population in the Middle East we decided to perform a review of the procedures performed in our hospital over a two-year period.

methodsSingle centre, retrospective observational study. All tracheostomies performed between January 2016 and January 2018 were included in the study. The primary outcome was the rate of tracheostomy complications. Multivariate logistic regression analysis was used to identify the independent factors associated with complications and decannulations.

resultsOne hundred sixty-four patients were included in the study. Percutaneous tracheostomy was performed in 99 patients (60.4%). Complications occurred in thirty-eight patients (23%). Higher Left ventricular ejection fraction (OR = 0.94, 95%CI: [0.898-0.985]) and percutaneous tracheostomy (OR = 0.107, 95%CI: [0.029-0.401]) were associated with lower complications. Good Eastern Cooperative Oncology Group (ECOG) performance status (OR = 4.1, 95%CI: [1.3-13.3]) and downsized tracheostomy tube (OR = 6.5, 95%CI: [2.0-21.0]) were associated with successful decannulations. Successful decannulation was associated with lower hospital mortality when compated to those who could not be decannulated (3.2% vs 33.3% p < 0.0001).

conclusionIn our older population with high comorbidities, percutaneous tracheostomies were associated with less complications than surgical tracheostomies. Patients with poor premorbid functional status and those who could not have their tracheostomy tube sucessfuly downsized were less likely to be decannulated, and had a higher mortality. This data enables physicians to inform the families of the added risks involved with tracheostomy in this patient group.
