Core Tip
Core Tip: The delta shock index (DSI) is defined as the change of SI value from the scene to the initial reading in the emergency unit (i.e., subtracting calculated SI at admission from SI at the scene). Among young trauma patients, high DSI is associated with severe injuries, more interventions, and worse outcomes (i.e., blood transfusion, exploratory laparotomy, ventilator-associated pneumonia, hospital length of stay, and in-hospital mortality). Apart from gender-biased observation, almost one-quarter of the study cohort had a higher DSI and were mostly young. High DSI correlated significantly with the other injury severity scores that need more time and imaging to be ready to use. Therefore, DSI is a practical, simple bedside tool for triaging and prognosis in young, injured patients.
