Epidemiology and Outcomes of ARDS After Pediatric Trauma
Bibliographic record
Abstract
BACKGROUND: Results of recent studies suggest that the incidence and mortality of ARDS may be higher than previously thought in pediatric trauma patients. We conducted a systematic review of the literature on incidence, risk factors, prognostic factors, and outcomes of ARDS after pediatric trauma in the ICU. METHODS: Medical literature databases were searched up to April 2020. Guidelines for reporting systematic reviews and meta-analyses were followed. Articles that reported quantitative data with regard to the incidence, risk factors, prognostic factors, mortality, or other outcomes for ARDS in subjects with pediatric trauma admitted to the ICU were included. Two authors independently screened and assessed eligibility of all identified studies, collected data, and assessed the methodological quality of selected studies. Data extraction was performed by using a standardized data extraction sheet. Quality assessment was performed by using the Newcastle-Ottawa scale for cohort studies. A meta-analysis was not performed because the studies used overlapping cohorts or different ARDS criteria. RESULTS: Nine studies were included. The incidence was reported in 4 studies, risk factors in 1, mortality in 7, and other outcomes in 2. The largest cohort included 148,749 subjects from a national trauma database. The ARDS incidence was 1.8%-7.6% when using adult ARDS criteria, with 1.8% in the largest cohort, and 4.2% when using pediatric ARDS criteria. Mortality was 7.6%-22.9% when using adult ARDS criteria and 11.1%-34.0% when using the pediatric ARDS criteria. Identified risk factors included mechanism of injury, higher injury severity scores, abnormal breathing frequencies, and lower Glasgow coma scale scores at hospital presentation. ARDS was associated with a longer duration of mechanical ventilation, longer ICU and hospital length of stay, and a higher likelihood of requiring post-discharge care. CONCLUSIONS: The ARDS incidence of 4.2% in the subjects with pediatric trauma in the ICU was comparable with 3.2% in the general pediatric ICU population; however, mortality associated with trauma-associated ARDS was higher and more commonly due to multi-system organ failure rather than hypoxemia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
