Abstract
BACKGROUND: The purpose of this study was to investigate trends in tracheostomy (TR) utilization among trauma patients over the last decade and explore its impact on mortality among elderly trauma patients. METHODS: Patients 18 years or older with at least 72 h on the ventilator were selected from the National Trauma Databank research datasets 2007 to 2015. Patients were divided into three groups based on age: 18-60, 61-80, and > 80 years and proportions of patients undergoing a TR were depicted. Elderly (> 80 years) were divided into two groups, based on whether they underwent a TR. The primary outcome was mortality. A Cox regression model with a time-dependent variable was utilized to account for survival bias. RESULTS: Over the 9-year study period 284,774 patients met inclusion criteria. Of those, 21,465 (7.5%) were older than 80 years. Elderly patients were significantly less likely to undergo a TR (13.1% vs. 21.5% in the 18-60 years and 20.4% in the 61-80 years group, p < 0.01) and this trend continued throughout the study period. Among the elderly patients, those who underwent TR were more likely to have a severe (AIS ≥ 3) thoracic, abdominal, and/or spinal injury, but not head injury and were less likely to have a history of cerebrovascular accident (5.9% vs. 7.7%, p < 0.01). The overall mortality was significantly higher in elderly patients who did not undergo a TR (46.9% vs. 17.6%, p < 0.01). The adjusted hazard ratio for elderly patients undergoing a TR was 0.36 (adjusted p < 0.01). CONCLUSION: In ventilated trauma patients, tracheostomy is less likely to be utilized in the elderly population compared to younger age groups. Amongst the elderly patients, performance of tracheostomy was associated with a significantly higher overall survival. Delaying or avoiding this procedure in the elderly trauma patient predominantly based on age might not be justified. STUDY TYPE: Prognostic/epidemiological. LEVEL OF EVIDENCE: III or IV.
