JAMA:关于先兆子痫筛查的证据报告和系统评估

2017-04-30 MedSci MedSci原创

先兆子痫是一种复杂的怀孕相关性疾病,其对母婴的发病率和死亡率有严重影响。通过妊娠后20周的高血压和蛋白尿或多系统受累的证据定义先兆子痫。近期,一项发表在权威杂志JAMA上的研究系统地审查美国预防服务工作组的先兆子痫筛查和风险评估的好处和危害。此项研究的数据来源于MEDLINE、PubMed和Cochrane对照试验数据库中心登记册,自1990年至2015年9月1日。目标出版物的新证据监测于2016

先兆子痫是一种复杂的怀孕相关性疾病,其对母婴的发病率和死亡率有严重影响。通过妊娠后20周的高血压和蛋白尿或多系统受累的证据定义先兆子痫。


近期,一项发表在权威杂志JAMA上的研究系统地审查美预防服务工作组的先兆子痫筛查和风险评估的好处和危害。

此项研究的数据来源于MEDLINE、PubMed和Cochrane对照试验数据库中心登记册,自1990年至2015年9月1日。目标出版物的新证据监测于2016年10月5日进行。

此项研究选择英语试验和观察性研究,包括外部验证的预测模型,妊娠期间常规先兆子痫筛查的有效性、益处和危害。

采用独立双重审查文章摘要。由于研究的临床和统计学异质性,此项研究未进行Meta分析。

此项研究的主要研究结果包括产妇和婴儿的健康结果,包括子痫、中风、死胎、早产和低出生体重儿;筛选和风险预测测试表现;筛查的危害和风险评估。

此项研究共包括21项研究(13982人)。没有研究直接比较筛查人群与未筛选人群的先兆子痫筛查的有效性;1项美国试验(n = 2764)发现,在产前检查较少的情况下,益处和害处之间没有差异;但是对于罕见的,严重的结果而言,功能不足。

对于危害,与常规筛查(n = 1952)相比,前后比较尿蛋白的筛查的特异性指标的非劣效性研究并未鉴定出较少的尿筛选试验的危害。

四项研究(n = 7123)报告了16项风险预测模型的外部验证性能,其中5项预测先兆子痫具有良好或更好的区分力(c统计学> 0.80),在最大、最适用的验证队列中阳性预测值为4%。尽管是关键的模型性能测量,但是没有报告校准。

无症状的初级保健人群中没有进行尿筛选试验的研究中,在被怀疑先兆子痫的孕妇中(n = 1888)进行蛋白质尿检测性能的14项研究发现,均具有广泛的检测准确性(敏感性,22%-100%,特异性,36%-100%),并且测试使用、资格标准和蛋白尿患病率的统计学和临床异质性较高(8.7%-93.8%)。

此项研究表明:进行先兆子痫筛查的好处和危害的证据以及在怀孕期间不同筛查方法的检测表现有限。外部验证的风险预测模型的适用性有限,缺乏支持常规使用所需的校准和临床实施数据。鉴于先兆子痫的复杂病理生理学和临床不可预测性,需要进一步研究以更好地指导基于风险的筛查方法并改进筛查策略。
