Inflammation Indıces and Mortality in Adult Crush Syndrome

This single-center, retrospective observational cohort study evaluated the prognostic value of complete blood count-derived inflammatory indices - the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), systemic inflammatory response index (SIRI), and pan-immune-inflammation value (PIV) - for the prediction of 28-day mortality in adult patients with crush syndrome admitted to the intensive care unit (ICU). Consecutive patients aged 18 years and older who were diagnosed with crush syndrome and admitted to the ICU between January 1, 2018, and September 30, 2025, were included. All indices were calculated from the complete blood count obtained within the first 24 hours of ICU admission. The primary and only outcome was 28-day mortality. The discrimination and independent prognostic value of the inflammatory indices were compared with the APACHE II and SOFA scores, and their incremental value beyond these established severity scores was assessed.
