Background Postnatal gestational age (GA) estimation is crucial in neonates with absent early trimester ultrasonography (USG) reports to evaluate the risk of morbidity and mortality. Widely used Expanded New Ballard (ENBS) is complex and needs an expert medical professional to assess. Eregie (ES) and Parkin (PS) scores are easy to perform with good inter-observer reliability. We aimed to compare these scores for their ability in predicting GA with early trimester USG-GA as the gold standard. Methods This cross-sectional study was conducted among 1114 intramural neonates who qualified according to the selection criteria. All neonates were evaluated using the three scores by residents (blinded to USG-GA) with a pre-defined inter-observer difference of <10%. Method applicability was compared in terms of accuracy, precision and validity. Results GA was systematically overestimated by 0.65, 0.68 and 0.32 weeks by ENBS, PS and ES, respectively. For GA subgroups, ES had better overall accuracy with mean difference of 0.32 ± 0.88 weeks. Validity was highest for ES (79.6%). Interpretation We conclude that all three scores were found to be of acceptable accuracy and validity. ES had better overall accuracy and validity among the subjects and for subgroups. In limited resource settings, ES or PS can substitute for ENBS.

扩展新 Ballard、Eregie 和 Parkin 评分在预测新生儿胎龄中的比较

背景 产后胎龄 (GA) 估计对于没有早期妊娠超声 (USG) 报告的新生儿评估发病率和死亡率的风险至关重要。广泛使用的扩展新巴拉德 (ENBS) 很复杂，需要专业的医疗专业人员进行评估。Eregie (ES) 和 Parkin (PS) 评分易于执行，具有良好的观察者间可靠性。我们的目的是比较这些分数在预测 GA 方面的能力，并以早孕期 USG-GA 作为黄金标准。方法 这项横断面研究是在 1114 名根据选择标准合格的壁内新生儿中进行的。所有新生儿均由居民（对 USG-GA 不知情）使用三个评分进行评估，预定义的观察者间差异小于 10%。比较方法适用性的准确性、精密度和有效性。结果 GA 分别被 ENBS、PS 和 ES 系统地高估了 0.65、0.68 和 0.32 周。对于 GA 亚组，ES 具有更好的总体准确度，平均差为 0.32 ± 0.88 周。ES 的有效性最高（79.6%）。解释 我们得出结论，所有三个分数都被发现具有可接受的准确性和有效性。ES 在受试者和亚组中具有更好的整体准确性和有效性。在资源有限的情况下，ES 或 PS 可以替代 ENBS。ES 在受试者和亚组中具有更好的整体准确性和有效性。在资源有限的情况下，ES 或 PS 可以替代 ENBS。ES 在受试者和亚组中具有更好的整体准确性和有效性。在资源有限的情况下，ES 或 PS 可以替代 ENBS。
