Abstract

Background: Postpartum hemorrhage (PPH) is considered as one of the major causes of maternal mortality worldwide. The most effective risk factors have been suggested in various studies on risk nomogram for the prediction of PPH. Aim: This study aimed to determine the diagnostic value of the risk nomogram for the prediction of PPH. Method: This study was performed prospectively using diagnostic methods on 600 women admitted to Omolbanin Hospital, Mashhad, Iran, from May to October 2017. The researcher measured and recorded the loss of blood volume in mothers using plastic blood collection bags and pads within 4 h after delivery. Subsequently, risk nomogram was completed for each study sample and the probability score for PPH was calculated by the researcher’s assistants. The obtained data were analyzed in SPSS software (Version 25). Ultimately, the receiver operating characteristic (ROC) curve of risk nomogram was plotted in this study. Results: The PPH occurred in 33.3% (n=200) of deliveries in this study. The area under the ROC curve was estimated at 81.2%. The point of 0.1 with 85.5% sensitivity and 51.5% specificity was also selected as the proposed cut-off point for this nomogram. Implications for practice: According to the results, the risk nomogram was considered as an appropriate method for the prediction of PPH. Therefore, it was recommended as a simple and noninvasive approach in childbirth for the prediction of PPH.

风险图预测阴道分娩后产后出血的诊断价值

背景:产后出血(PPH)被认为是全世界孕产妇死亡的主要原因之一。在各种预测PPH的风险图研究中，已经提出了最有效的危险因素。目的:探讨风险图对PPH的诊断价值。方法:采用前瞻性诊断方法对2017年5月至10月在伊朗马什哈德Omolbanin医院住院的600名妇女进行研究。研究人员测量并记录了母亲在分娩后4小时内使用塑料采血袋和采血垫的血量损失。随后，完成每个研究样本的风险图，并由研究人员的助手计算PPH的概率得分。所得数据在SPSS软件(Version 25)中进行分析。最终绘制出受试者工作特征(ROC)风险nomogram曲线。结果:本组产妇PPH发生率为33.3% (n=200)。ROC曲线下面积估计为81.2%。0.1点的敏感性为85.5%，特异性为51.5%，作为该nomogram的建议截断点。实践意义:根据研究结果，认为风险表是预测PPH的合适方法。因此，它被推荐为分娩时预测PPH的一种简单且无创的方法。

期刊介绍： The Evidence Based Care Journal (EBCJ) is an international, peer reviewed, scientific journal that seeks to promote the development and exchange of knowledge that is directly relevant to all spheres of patient care. The primary aim is to promote a high standard of clinically related scholarship which advances and supports patient care in practice. The Journal also aims to promote the international exchange of ideas and experience that draws from the different cultures in which practice takes place. Further, EBCJ seeks to enrich insight into clinical needs and the implications for patient care intervention and models of service delivery. Emphasis is placed on clinical practicality of research findings and strength of study design. EBCJ is essential reading for anyone involved in healthcare professions, whether clinicians, researchers, educators, managers, policy makers, or students. Contributions are welcomed from other health professionals on issues that have a direct impact on patient care.
