Earlier Tracheostomy Reduces Complications in Complete Cervical Spinal Cord Injury in Real-World Practice: Analysis of a Multicenter Cohort of 2001 Patients
Bibliographic record
Abstract
BACKGROUND AND OBJECTIVES: It is believed that early tracheostomy in patients with traumatic cervical spinal cord injury (SCI) may lessen the risk of developing complications and reduce the duration of mechanical ventilation and critical care stay. This study aims to assess whether early tracheostomy is beneficial in patients with traumatic cervical SCI. METHODS: We conducted a retrospective cohort study using data from the American College of Surgeons Trauma Quality Improvement Program database from 2010 to 2018. Adult patients with a diagnosis of acute complete (ASIA A) traumatic cervical SCI who underwent surgery and tracheostomy were included. Patients were stratified into those receiving early (at or before 7 days) and delayed tracheostomy. Propensity score matching was used to assess the association between delayed tracheostomy and the risk of in-hospital adverse events. Risk-adjusted variability in tracheostomy timing across trauma centers was investigated using mixed-effects regression. RESULTS: The study included 2001 patients from 374 North American trauma centers. The median time to tracheostomy was 9.2 days (IQR: 6.1-13.1 days), with 654 patients (32.7%) undergoing early tracheostomy. After matching, the odds of a major complication were significantly lower for early tracheostomy patients (OR: .90; 95% CI: .88-.98). Patients were also significantly less likely to experience an immobility-related complication (OR: .90; 95% CI: .88-.98). Patients in the early group spent 8.2 fewer days in the critical care unit (95% CI: -10.2 to -6.61) and 6.7 fewer days ventilated (95% CI: -9.44 to -5.23). There was significant variability in tracheostomy timeliness between trauma centers with a median odds ratio of 12.2 (95% CI: 9.7-13.7), which was not explained by case-mix and hospital-level characteristics. CONCLUSION: A 7-day threshold to implement tracheostomy seems to be associated with reduced in-hospital complications, time in the critical care unit, and time on mechanical ventilation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
