BACKGROUND: In addition to trauma center levels and types, trauma volume may be an important factor impacting outcomes in severe pediatric trauma.
METHODS: All severely injured pediatric patients treated at adult trauma centers were identified from the National Trauma Data Bank. All qualifying centers were stratified into four groups based on the cumulative pediatric trauma case volumes with ISS >15: lowest (group 1), lower (group 2), higher (group 3), and highest (group 4) volume centers. Mortality rates among the groups were compared.
RESULTS: A total of 3747 patients were stratified into group 1 (n=2122, median annual pediatric trauma volume 3 cases/year), group 2 (n=842, 15 cases/year), group 3 (n=494, 24 cases/year), and group 4 (n=289, 43 cases/year). In the hierarchical logistic regression analysis, the highest volume centers (group 4) were shown to have improved mortality (odds ratio 0.474, 95% confidence interval [CI] 0.301-0.747) compared to the lowest volume centers (group 1). Odds ratios of group 4 against group 1 for subgroups were 0.634 (age<10, 95% CI 0.335-1.198), 0.491 (blunt injury, 95% CI 0.310-0.777), and 0.495 (level 1 center, 95% CI 0.312-0.785).
CONCLUSIONS: In severe pediatric trauma treated at adult trauma centers, higher volume centers were associated with improved mortality in comparison to the lower volume centers. LEVEL OF EVIDENCE: Level III, therapeutic/care management, retrospective comparative study without negative criteria.
