ObjectivesTo evaluate the optimal timing of tracheostomy for injured adolescents.DesignRetrospective cohort study.SettingTrauma facilities in the United States.PatientsAdolescents (age 12-17 yr) in the National Trauma Data Bank (2007-2016) who were ventilated for greater than 24 hours and survived to discharge.InterventionsNone.Measurements And Main ResultsAfter stratifying by traumatic brain injury diagnosis, we compared ICU and hospital length of stay, pneumonia, and discharge disposition of patients with tracheostomy prior to three cut points (3, 7, and 14 d after admission) to 1) patients intubated at least as long as each cut point and 2) patients with tracheostomy on or after each cut point. Of 11,045 patients, 1,391 (12.6%) underwent tracheostomy. Median time to tracheostomy was 9 days (interquartile range, 6-13 d) for traumatic brain injury and 7 days (interquartile range, 3-12 d) for nontraumatic brain injury patients. Nontraumatic brain injury patients with tracheostomy prior to 7 days had 5.6 fewer ICU days (-7.8 to -3.5 d) and 5.7 fewer hospital days (-8.8 to -2.7 d) than patients intubated greater than or equal to 7 days and had 14.8 fewer ICU days (-19.6 to -10.0 d) and 15.3 fewer hospital days (-21.7 to -8.9 d) than patients with tracheostomy greater than or equal to 7 days. Similar differences were observed at 14 days but not at 3 days for both traumatic brain injury and nontraumatic brain injury patients. At the 3- and 7-day cut points, both traumatic brain injury and nontraumatic brain injury patients with tracheostomy prior to the cut point had lower risk of pneumonia and risk of discharge to a facility than those with tracheostomy after the cut point.ConclusionsFor injured adolescents, tracheostomy less than 7 days after admission was associated with improved in-hospital outcomes compared with those who remained intubated greater than or equal to 7 days and with those with tracheostomy greater than or equal to 7 days. Tracheostomy between 3 and 7 days may be the optimal time point when prolonged need for mechanical ventilation is anticipated; however, unmeasured consequences of tracheostomy such as long-term complications and care needs must also be considered.Copyright © 2021 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.
