Prognostic significance of systemic inflammation response index, systemic immune-inflammation index and neutrophil-to-lymphocyte ratio in patients with chronic subdural hematoma after burr hole drainage

To our knowledge, this is the first study to examine the prognostic significance of admission SIRI in CSDH patients. In this study, SIRI and NLR had prognostic significance in CSDH patients after burr hole drainage. When combined with the basic model (history of ischemic stroke, brain herniation, admission GCS, anticoagulant or antiplatelet therapy), the SIRI has better predictive accuracy (C-index 0.862 vs. 0.861) and model-fitting (AIC 321.98 vs. 325.61) than NLR.
