Neonatal Early-Onset Sepsis Risk Assessment
Early-onset neonatal sepsis (EOS) is a potentially life-threatening infection occurring within the first 72 hours of life. The Neonatal Sepsis Calculator estimates the risk of EOS in newborns based on maternal and perinatal risk factors, supporting evidence-based decisions regarding observation, laboratory evaluation, or empiric antibiotics. This tool is intended for infants born at or after 34 weeks’ gestation and should be used by clinicians experienced in newborn care. The calculation incorporates local EOS incidence, maternal temperature, gestational age, duration of membrane rupture, GBS status, intrapartum antibiotics, and the newborn’s clinical presentation.
How to Use the Neonatal Sepsis Calculator for Early-Onset Risk
Step One: Enter the baseline incidence of early-onset sepsis (EOS) in your local population, expressed per 1000 live births. This value is often available from institutional or regional data.
Step Two: Provide the newborn’s gestational age in weeks, highest maternal antepartum temperature in degrees Celsius, and the duration of membrane rupture in hours. Accurate input of these values ensures the most reliable risk estimate.
Step Three: Select the maternal Group B Streptococcus (GBS) status and specify whether intrapartum antibiotics were administered. These details reflect key risk factors for neonatal infection.
Step Four: Indicate the newborn’s clinical presentation by choosing between well-appearing, equivocal, or clinical illness. This information adjusts the risk calculation and guides management recommendations.
Step Five: Click the “Calculate Risk” button to view the estimated EOS risk per 1000 births, along with a concise recommendation and a brief explanation of the calculation process. Use this information to support clinical decision-making regarding observation, laboratory evaluation, or empiric antibiotics.
