Abstract

To forecast mortality and identify adult patients who required admission to an intensive care unit (ICU), we compared the efficacy of the most widely used early warning scores. The present review assessed the pulmonary embolism and risk factors of ICU admission; systematic review. A search of the literature was conducted in the bibliographic databases PubMed and EMBASE between 2009 and 2022. Each reviewer verified independently that each possibly relevant title and abstract qualified. There were nine studies that were included in the review. National early warning score (NEWS) was the best indicator of ICU admission; however, the modified early warning score (MEWS) performed better in sepsis patients. According to emergency department (ED) Mortality, the NEWS was the most accurate score for predicting mortality in the entire ED population, and the mortality in emergency department sepsis score was the most accurate measure for patients with sepsis. For all endpoints, NEWS and MEWS had good outcomes in the ICU and ED. Numerous investigations should be conducted utilizing various prognostic scores on ED and ICU patients. Anemia in patients with venous thrombosis was associated with a higher risk of ICU admission and mortality.
