目的：日本妇产科学会（JSOG）围产期委员会提出了基于5级（1-5级）胎儿心率分级的产时管理指南。本研究旨在评估该分类的可重复性和临床实用性。方法：为了评估胎儿心率描记解释在观察者内和观察者间的可重复性，2名产科医生使用JSOG分类（1级，正常；2级，良性变异；3级，轻度变异；4级，中度变异；5级，严重变异）和主观3级分类（正常、模糊和不祥）回顾了247例胎儿心率描记。在一个单独的系列中，我们调查了96例分娩中JSOG分类是否与新生儿早期结局和分娩方式有关。结果：基于JSOG分类解释胎儿心率描记的观察者内和观察者间再现性加权kappa系数分别为0.73 ~ 0.77和0.70。主观分类值分别为0.69 ~ 0.72和0.59。在JSOG分类的5个级别中，器械或剖宫产的发生率逐渐增加(P
Aim: Intrapartum management guidelines based on fetal heart rate classification comprising a 5-tier system (Levels 1-5) was proposed by the Perinatology Committee of the Japan Society of Obstetrics and Gynecology (JSOG). This study aimed to assess the reproducibility and clinical usefulness of this classification.Methods: For assessing intraobserver and interobserver reproducibility in the interpretation of fetal heart rate tracing, 2 obstetricians reviewed 247 fetal heart rate tracings using the JSOG classification (Level 1, normal; Level 2, benign variant; Level 3, mild variant; Level 4, moderate variant; and Level 5, severe variant) and a subjective 3-tier classification (normal, equivocal, and ominous). In a separate series, we investigated whether the JSOG classification is related to early neonatal outcome and the delivery mode in 96 deliveries.Results: Weighted kappa coefficients of intraobserver and interobserver reproducibility in the interpretation of fetal heart rate tracings based on the JSOG classification were 0.73 to 0.77 and 0.70, respectively. In the subjective classification, these values were 0.69 to 0.72 and 0.59. There was a progressive increase in the rate of instrumental or cesarean deliveries across the 5 levels of the JSOG classification (P
