Association of Pneumonia, Wound Infection, and Sepsis with Clinical Outcomes after Acute Traumatic Spinal Cord Injury
Bibliographic record
Abstract
Pneumonia, wound infections, and sepsis (PWS) are the leading causes of acute mortality after traumatic spinal cord injury (SCI). However, the impact of PWS on neurological and functional outcomes is largely unknown. The present study analyzed participants from the prospective North American Clinical Trials Network (NACTN) registry and the Surgical Timing in Acute SCI Study (STASCIS) for the association between PWS and functional outcome (assessed as Spinal Cord Independence Measure subscores for respiration and indoor ambulation) at 6 months post-injury. Neurological outcome was analyzed as a secondary end-point. Among 1299 participants studied, 180 (14%) developed PWS during the acute admission. Compared with those without PWS, participants with PWS were mostly male (76% vs. 86%; p = 0.007), or presented with mostly American Spinal Injury Association Impairment Scale (AIS) grade A injury (36% vs. 61%; p < 0.001). There were no statistical differences between participants with or without PWS with respect to time from injury to surgery, and administration of steroids. Dominance analysis showed injury level, baseline AIS grade, and subject pre-morbid medical status collectively accounted for 77.7% of the predicted variance of PWS. Regression analysis indicated subjects with PWS demonstrated higher odds for respiratory (odds ratio [OR] 3.91, 95% confidence interval [CI]: 1.42-10.79) and ambulatory (OR 3.94, 95% CI: 1.50-10.38) support at 6 month follow-up in adjusted analysis. This study has shown an association between PWS occurring during acute admission and poorer functional outcomes following SCI.

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.
