Key result
ΔSI ≥ 0.1 predicts emergency surgery in-hospital mortality with ~87% specificity.
Why the study?
The shock index and modified shock index have proven prognostic value in trauma, but their role in non-trauma emergency surgery remains unclear.
Do dynamic changes in shock index (ΔSI) between ED admission and the preoperative period predict in-hospital mortality in adults undergoing emergency surgery?
Do dynamic changes in shock index (ΔSI) between ED admission and the preoperative period predict in-hospital mortality in adults undergoing emergency surgery?
A dynamic increase in shock index (ΔSI ≥ 0.1) between ED admission and surgery is a highly specific and independent predictor of in-hospital mortality in emergency surgery patients.

May aid preoperative risk stratification in emergency surgery; extends SI data but hypothesis-generating pending prospective validation.
Çakmak et al. (2026) studied this question. A ΔSI ≥ 0.1 predicted in-hospital mortality with 87% specificity, identifying high-risk patients in emergency surgery.
