Functional Impact of a Minor Thoracic Injury
Bibliographic record
Abstract
OBJECTIVE: To investigate whether minor thoracic injuries (MTIs) relate to subsequent functional limitations. BACKGROUND: Approximately 75% of patients with an MTI are discharged after an emergency department (ED) visit, whereas significant functional limitations can occur in the weeks that follow. METHODS: A 19 months' prospective cohort study with a 90-day follow-up was conducted at 4 university-affiliated EDs. Patients 16 years and older with an MTI were assessed at initial ED visit, 7, 14, 30, and 90 days after injury. Functional outcome was measured using the SF-12 scale. General linear model were used to assess outcome. RESULTS: A total of 482 patients were included, of whom 127 (26.3%) were 65 or older. Overall, 147 patients (30.5%) presented with at least 1 rib fracture and 59 subjects (12.2%) with delayed hemothorax. At 90 days, 22.8% of patients still had severe or moderate disabilities on global physical health score. Patients with solely delayed hemothorax and no rib fracture had the lowest global physical health score (46.4 vs 61.1, P < 0.01, effect size = -2.60) than patients with simple MTI. Generally, functional limitations also increase with increments of number of rib fracture detected on radiograph. Outcomes were not different among patients 65 years or older when compared to their younger counterparts. CONCLUSIONS: In this prospective study of MTIs, severe to moderate disabilities were present in nearly 1 patient out of 5 at 90 days. The presence of delayed hemothorax and the number of rib fracture were associated with increased functional limitations after a MTI.

How this classification was reachedexpand
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.
