Reverse shock index multiplied by Glasgow Coma Scale score as a predictor of urgent trauma care and mortality in isolated severe traumatic brain injury: a 10-year nationwide validation study.

ABSTRACT:

Background

Patients with traumatic brain injuries (TBIs) have high mortality rates and poor outcomes. Predicting the need for urgent interventions, as well as mortality risk, is crucial for optimizing trauma management. This study aimed to identify and validate the reverse shock index multiplied by the Glasgow Coma Scale score (rSIG) as an assessment tool for predicting urgent interventions, critical care, and mortality in patients with isolated severe TBIs.

Methods

This retrospective nationwide validation study analyzed data from the Japan Trauma Data Bank between January 1, 2012, and December 31, 2021. The population was divided into derivation (2012-2018) and validation (2019-2021) cohorts. The primary composite outcome included blood transfusions within 24 hours of hospi
