Validation of Quality Indicators for Pediatric Trauma Care
Bibliographic record
Abstract
OBJECTIVE: To develop metrics for pediatric-specific quality indicators (QIs) for trauma care using trauma registry data and evaluate their validity. BACKGROUND: A set of 23 QIs specific to pediatric trauma care and applicable to both pediatric and non-pediatric trauma centers (PTCs) was recently developed. Their validity needs to be assessed before implementation. METHODS: We extracted data on children admitted to any trauma center in a Canadian provincial trauma system between April 2016 and March 2022. We evaluated QIs using Agency for Healthcare Research and Quality criteria. RESULTS: The study sample comprised 10,711 pediatric trauma admissions. We developed metrics for 15 QIs. Six had moderate-to-high validity on all evaluable criteria: head computed tomography <60 minutes for children with Glasgow Coma Scale <13, documentation of a full set of vital signs in the emergency department, initial head computed tomography in patients at low-risk on a clinical decision rule, stabilization of femoral shaft fractures <24 hours, intracranial pressure monitoring in severe traumatic brain injury, and nutritional support <48 hours of intensive care unit admission. Four had moderate-to-high validity on all but one criterion: PTC transfer for neurotrauma and major multisystem trauma, PTC transfer for major orthopedic trauma, and antibiotics <60 minutes in open long bone fractures. CONCLUSIONS: This study shows the feasibility of operationalizing QIs for pediatric trauma using trauma registry data, and we provide coding definitions to do so. Results provide evidence on validity that may be used to guide the selection of QIs for performance improvement programs.

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.
