Predicting the need for early tracheostomy: a multifactorial analysis of 992 intubated trauma patients.
BACKGROUND
Tracheostomy has few, severe risks, while prolonged endotracheal intubation causes morbidity. The need for tracheostomy was assessed, based on early clinical parameters.


METHODS
Adult trauma patients (January 1994-August 2004), intubated for resuscitation, ventilated >24 hours, were retrospectively evaluated for demographics, physiology, brain, and pulmonary injury. Tracheostomy patients were compared with those without. Chi-square, Mann-Whitney, and multivariate logistic regression were used with statistical significance at p < 0.05.*


RESULTS
Of 992 patients, 430 (43%) underwent tracheostomy at 9.22 +/- 5.7 days. Risk factors were age (45.6* +/- 18.8 vs. 36.7 +/- 15.9, OR: 2.1 (18 years increments), ISS (30.3* +/- 12.5 vs. 22.0 +/- 10.3, OR: 2.1 (12u increments), damage control (DC) [68%*(n = 51) vs. 32%*(n = 51), OR: 3.8], craniotomy [70%*(n = 21) versus 30%(n = 9), OR: 2.6], and intracranial pressure monitor (ICP) [65.4%*(n = 87) vs. 34.6%(n = 46), OR: 2.1]. A 100% tracheostomy rate (n = 30, 3.0%) occurred with ISS (injury severity score) = 75, ISS >or=50, and age >or=55, admit/24 hour GCS (Glasgow Coma Scale) = 3 and age >or=70, AIS abdomen, chest or extremities >or=5 and age >or=60, bilateral pulmonary contusions (BPC) and >or=8 rib fractures, craniotomy and age >or=50, craniotomy with intracranial pressure (ICP) and age >or=40, or craniotomy and GCS <or=4 at 24 hour.A tracheostomy rate of >or=90% (n = 105, 10.6%) was found with ISS >or=54, ISS >or=40, and age >or=40, admit/24 hour GCS = 3 and age >or=55, paralysis and age >or=40, BPC and age >or=55.A tracheostomy rate >or=80% (n = 248, 25.0%) occurred with ISS >or=38, age >or=80, admit/24 hour GCS = 3 and age >or=45, DC and age >or=50, BPC and age >or=50, aspiration and age >or=55, craniotomy with ICP, craniotomy with GCS <or=9 at 24 hour.


CONCLUSIONS
Discrete risk factors predict the need for tracheostomy for trauma patients. We recommend that patients with >or=90% risk undergo early tracheostomy and that it is considered in the >or=80% risk group to potentially decreased morbidity, increased patient comfort, and optimize resource utilization.
