Admission Emergency Department Point-of-care Biomarkers for Prediction of Early Mortality in Spontaneous Intracerebral Hemorrhage

hemorrhage (sICH) has a significant morbidity and mortality, despite representing a non-dominant hemorrhagic stroke. The aim of the study was to assess the impact of the emergency department (ED) point-of-care (POC) biomarkers on early mortality in sICH patients. Patients and Methods: Demographic data, medical history and admission clinical parameters from adult patients with imaging-based sICH diagnosis were collected retrospectively, upon their ED presentation over a period of 18 months. ED-based POC analyzers were used for blood biomarkers [complete blood count, C reactive protein (CRP), glycemia, hepatic and renal function, D-dimer and cardiac troponin I]. Derived inflammatory indexes were calculated. Mortality endpoints were collected (on day 7 and at discharge). Results: Of the 219 included patients, mortality rates reached 30.14% on day 7 and 46.12% at discharge. In the univariate analysis, day 7 mortality was significantly associated with history of diabetes, atrial fibrillation, ongoing anticoagulant treatment, the need of endotracheal intubation and ED cardiopulmonary resuscitation, and the presence of intraventricular hemorrhage and mass effect on the initial CT scan. White blood cells and granulocytes (but not the neutrophil-tolymphocytes ratio, nor the CRP) were significantly higher in the deceased groups, alongside serum glucose. Derived inflammatory indexes were not significantly correlated with mortality endpoints. Cut-off values of 9.6x109/l for granulocytes and 132 mg/dl for glucose were identified as day 7 mortality predictors. Conclusion: sICH is a potentially severe condition causing high early mortality. Emergency department point-of-care biomarkers could represent a readily available and simple to use prognostic tool.

Automated summary

This study aimed to assess the impact of emergency department point-of-care biomarkers on early mortality in patients with acute intracerebral hemorrhage (sICH). The study found that these biomarkers could serve as a readily available and simple to use prognostic tool, helping to predict the mortality rate of patients.
