Enhanced Category-Based Risk Assessment for Neonatal Early-Onset Sepsis: A Prospective Observational Study.

Introduction: Compared with multivariate risk assessment, traditional category-based risk assessment (CRA) approaches for neonatal early-onset sepsis (EOS) screening are usually straightforward to use, do not require electronic devices, but are associated with higher rates of antibiotic use. This study aims to evaluate the performance of a novel enhanced CRA (eCRA) framework on EOS admissions and antibiotic use and to investigate whether a modified version with adjustments in risk factor weighting can allow its performance to match the EOS calculator while remaining easy to implement.

Method: This is a prospective, single-center, two-phase observational study.
