Age-adjusted shock index vs. reverse shock index multiplied by Glasgow Coma Scale to evaluate mortality in pediatric trauma: a systematic literature review and meta-analysis

Early identification of high-risk pediatric trauma patients is essential for timely intervention. The Shock Index, Pediatric Age-adjusted (SIPA) and the reverse Shock Index multiplied by Glasgow Coma Scale (rSIG, including rSIM variants) are commonly studied physiologic scores that have not been systematically compared. This study evaluated and compared the performance of SIPA and rSIG/rSIM for predicting mortality in pediatric trauma, and secondarily, blood product transfusion and other resource-use outcomes.
