Effectiveness of the Full Outline of UnResponsiveness Score in Patients With Acute Ischemic Stroke.

Background Predicting the mortality and prognosis of patients with stroke is one of the commonly studied topics. Various scoring systems have been used in this regard. One of them is the Full Outline of UnResponsiveness (FOUR) score. In this study, we aimed to investigate the utility of the FOUR scores in terms of their ability to predict hospital stay duration and mortality in patients who were diagnosed with ischemic stroke upon their admission to the emergency department. Methods Our study is a prospective observational study. Patients who were admitted to the emergency department of a tertiary hospital and diagnosed with ischemic stroke between August 1, 2020, and August 1, 2021, were included in the study. The inclusion criteria were as follows: being over the age of 18, being diagnosed with ischemic stroke, having symptoms that started within the last 48 hours, and patient consent approved by the patients themselves or their relatives. The patients were divided into two groups according to the FOUR scores (FOUR score = 16 and FOUR score < 16). Patients' demographic information, vital parameters, symptoms, time to admission, comorbidities, laboratory parameters, length of hospitalization, mortality, and Glasgow Coma Scale (GCS), FOUR, and National Institutes of Health Stroke Scale (NIHSS) scores were recorded. Results A total of 79 patients were included in the current study, of which 47 (59.5%) were male. The patients included in the present study had a mean age of 66 ± 13 years. When the two groups of patients with a FOUR score of 16 and a FOUR score of below 16 were compared, the mean platelet count was found to be 248 ± 70 × 10
