Can the shock index be a reliable predictor of early mortality after trauma in older patients? A retrospective cohort study.

ABSTRACT:

Aim

Older patients have different physiological characteristics; thus, the reliability of the shock index (SI) to predict mortality could depend on age. We investigated whether the SI is a reliable predictor of early mortality in older patients and evaluated the clinical benefit of age in the interpretation of the SI.

Methods

Using data from the Japan Trauma Data Bank, we identified injured patients aged 20-84 years. Area under the receiver operating characteristic curve (AUC) was used to evaluate the discrimination ability of the SI to predict early mortality. A formula to determine the cut-off for each age was derived using linear regression analysis. Performance of the new method was compared with that of the traditional SI cut-off of ≥0.9 AUC.

Results

We analyzed
