Multi-institutional search for patient factors associated with adverse events following tracheotomy.

Background: Tracheotomy is a common procedure for otolaryngologists. The risk of complications is difficult to predict. This study aims to identify measurable preoperative indicators associated with adverse events following tracheotomy.Methods: The charts of adults undergoing tracheotomy for respiratory failure at one of four university-affiliated hospitals between 1/2012 and 8/2018 were reviewed. Complications were analyzed in the context of de-mographics, physiologic parameters, and comorbidities.Results: Among 507 tracheotomies performed, the most common complications included infection, bleeding, and cardiac arrest. Mortality was 39 % in patients with pulmonary hypertension, 42 % in those with ejection fraction & LE; 40 and 32 % in those with abnormal right ventricular function, double the rates in patients without each of these findings.Conclusion: Many critically ill tracheotomy patients experience significant rates of adverse events. Risk factors for mortality include ejection fraction & LE; 40, pulmonary hypertension, and abnormal ventricular function. These should be considered for use in preoperative counseling. Level of evidence: 4.
