RESUMO
Early-onset sepsis (EOS) continues to be a significant cause of mortality and morbidity in neonates, with difficulty in early identification and a worse prognosis if the treatment is delayed. Clinically, a comprehensive evaluation is usually carried out according to high-risk factors in the perinatal period, early clinical manifestations after birth, and laboratory tests of patients. early empirical antibiotic treatment as soon as possible in suspected cases. However, there is an evidence gap for the standardized evaluation of the EOS risk factors and clinical manifestation, leading to unnecessary early antibiotic treatment in those neonates who are misdiagnosed with neonatal sepsis, resulting in adverse outcomes in the short and long term. Neonatal EOS risk calculator (NEOSC), a new quantitative algorithm for the evaluation of EOS risk in neonates in recent years, has been extensively reached in some developed countries and has been applied in clinical research, providing a new strategy to guide early antibiotic management in patients with suspected EOS. This review summarizes the research progress on NEOSC and its clinical application.
