Retrospective Evaluation of Hematological and Clinical Factors Associated with 30-Day Mortality in 170 Patients Diagnosed with Intracerebral Hematoma in a Single Center in Turkey.

Abstract

BACKGROUND This retrospective study from a single center in Turkey aimed to evaluate hematological and clinical factors related with 30-day mortality in patients diagnosed with intracerebral hematoma (ICH) between 2013 and 2021. MATERIAL AND METHODS All 170 consecutive patients (>18 years) admitted to the Intensive Care Unit (ICU) with spontaneous ICH were analyzed. Cranial computed tomography was performed in all patients. Venous blood samples were routinely obtained upon admission. Demographic characteristics, blood test results, imaging data, and survival data were retrieved from the institutional digital database. The primary goal of this study was to investigate the role of presenting demographic and clinical characteristics and blood tests in predicting 30-day mortality in patients with spontaneous ICH. RESULTS Receiver operating characteristic curve analysis showed that the Glasgow coma scale (GCS) score (≤9), hematoma volume (>13.4 cm³), hemoglobin (≤13.1 g/dL), international normalized ratio (>1.25), C-reactive protein (CRP) (>7.5 mg/L), and third-day neutrophil-to-lymphocyte ratio (>17.8) could be used to predict 30-day mortality. Patients with low GCS scores (≤9) had a 14.432-fold higher risk of death than other patients (OR: 14.432, 95% CI: 6.421-32.441, P<0.001). Patients with high CRP levels (>7.5) had a 3.323-fold higher risk of death than other patients (OR: 3.323, 95% CI: 1.491-7.405, P=0.003). CONCLUSIONS Tailoring scoring systems to include CRP may be beneficial for predicting spontaneous ICH prognosis. However, further studies assessing CRP and other inflammatory markers are necessary to assess whether inflammatory activity could be associated with worse outcomes in patients with ICH.
