Predictive Value of Systemic Immune-Inflammation Index Combined with D-Dimer Levels and Injury Severity Score for the Prognosis of Patients with Multiple Injuries: A Retrospective Analysis
Retrospective analysis predicts outcomes in multiple injuries using immune-inflammation index, D-dimer, and injury severity score, indicating clinical relevance.
Key Points
The study aims to evaluate the prognostic value of combining systemic immune-inflammation index, D-dimer, and injury severity score in patients with multiple injuries.
Analyzed 142 patients with multiple injuries retrospectively from an emergency department.
Categorized patients into survival and non-survival groups based on postoperative outcomes.
Used logistic regression for significant indicators to determine prognostic factors.
Assessed predictive value via receiver operating characteristic curves.
Median SII significantly differed between survival (340.11) and non-survival (849.93) groups (P<0.001).
SII, D-D, and ISS were identified as independent prognostic factors for mortality.
Combination of SII, D-D, and ISS showed high predictive accuracy (AUC=0.969) for 28-day mortality.
Patients with SII ≤ 308.8 had significantly lower mortality (P<0.05).
