A Prospective Evaluation of the Utility of a Hybrid Operating Suite for Severely Injured Patients
Bibliographic record
Abstract
OBJECTIVE: The primary objective of this study was to evaluate the utility, clinical impact, and work flow of a new trauma hybrid operating theater. SUMMARY BACKGROUND DATA: The potential utility and clinical benefit of hybrid operating theaters are increasingly postulated. Unfortunately, the clinical outcomes and efficiencies of these environments remain unclear. METHODS: All severely injured patients who were transferred to the hybrid suite for emergent intervention between 2013 and 2017 were compared to consecutive prehybrid patients. Standard statistical methodology was employed (P < 0.05 = significant). RESULTS: One hundred sixty-nine patients with severe injuries (mean ISS = 23; hemodynamic instability = 70%; hospital/ICU stay = 12 d; mortality = 14%) were transferred urgently to the hybrid suite. Most were young (38 yrs) males (84%) with blunt injuries (51%). Combined hybrid trauma procedures occurred in 18% of cases (surgery (82%) and angiography (11%) alone). Procedures within the hybrid suite included: laparotomy (57%), extremity (14%), thoracotomy/sternotomy (12%), angioembolization of the spleen/pelvis/liver/other (9%), neck (9%), craniotomy (4%), and aortic endostenting (6%). Compared with historical controls, use of the hybrid suite resulted in shorter arrival to intervention and total procedure times (P < 0.05). A clear benefit for survival was evident (42% vs. 22%). CONCLUSIONS: Availability of a hybrid environment for severely injured patients reduces time to intervention, total procedural duration, blood product transfusion and salvages a small subset of patients who would not otherwise survive. The cost associated with a hybrid suite remains prohibitive for many centers.

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.
