Determination of the Diagnostic Accuracy of Simplified Gestational Age Assessment Score in Assessment of Gestational Age in Neonate More than 28 Weeks – A Cross-Sectional Study

Introduction: Gestational age assessment is not only a vital step in management of mother but also important for fetus and newborn. Measuring gestational age is utmost important during antenatal period for numerous interventions and for prevention of troublesome pregnancies. Hence the aim of this study is to determine the diagnostic accuracy of SGAS in assessment of gestational age at birth. Method: A cross-sectional study was performed with 399 neonates > 28 weeks to determine the diagnostic accuracy of SGAS in assessment of gestational age at birth and to it to best obstetric estimate (BOE) in identifying preterm newborn >28weeks. New Ballard score and SGAS scoring was done for the same. Results: The positive correlation between gestational age, NBS, and SGA is significant (p-value <0.00). A strong correlation of gestational age for days and weeks is observed, as both were calculated using the LMP. Similarly, moderate levels of positive correlations between NBS and gestational age were observed at several weeks and weeks of gestational age. The positive correlation between NBS and SGA is strong with a correlation coefficient of 0.752, and the correlation between SGA and gestational age is moderate (r = 0.485). Conclusion: Tertiary care should focus on improving dating during pregnancy by ultrasound and improving validity in growth-restricted populations. Where ultrasound is not possible, multiple methods for newborn assessment are used of which Simplified gestational age assessment score plays an important role in assessing gestational age in neonate more than 28 weeks.
