PLOS MED:微创解剖对莫桑比克的儿童死因测定的有效性:观察性研究

2017-06-21 MedSci MedSci原创

在莫桑比克这一系列儿童死亡事件中,MIA显示与CDA大量一致。这种微创方法比更具侵入性的CDA更简单和更容易接受,可以为CoD监测提供强大的数据,特别是在资源有限的环境中,这可能有助于指导未来的儿童生存策略。

背景:近几十年来,世界在儿童生存方面取得了前所未有的进展。然而,我们对在中低收入国家每年导致近600万名儿童死亡的了解仍然很差,部分原因在于这些情况下目前利用的调查死因原因(CoD)的方法不足和精确度下降。研究目的是验证使用微创尸体解剖(MIA)方法作为在恶劣环境下进行儿科CoD调查的完整诊断尸体解剖(CDA)的适当和更可接受的替代品。

方法和结果:在这项观察性研究中,莫桑比克转诊医院在54例新生儿儿童死亡(年龄范围:≥1 mo至15 y)中评估了MIA方法在确定CoD方面的有效性,将MIA的结果与的CDA比较。通过两种方法获得的疾病类别的一致性通过Kappa统计学进行评估,并计算MIA诊断的敏感性,特异性和阳性和阴性预测值。

在CDA和MIA中的52/54(96%)病例中都发现了CoD,其中感染和恶性肿瘤占绝大多数诊断。MIA分类疾病与CDA分类结果基本一致(Kappa = 0.70,95%CI 0.49-0.92),敏感性,特异度和总体准确度较高。ICD-10诊断符合率高达75%(36/48)。可以通过添加一些基本临床信息(例如通过口头尸检或临床记录确定的临床信息)来最小化个体诊断中MIA和CDA之间的差异。分析的主要限制是,MIA和CDA都包含一定程度的专家主观解释。

结论:在莫桑比克这一系列儿童死亡事件中,MIA显示与CDA大量一致。这种微创方法比更具侵入性的CDA更简单和更容易接受,可以为CoD监测提供强大的数据,特别是在资源有限的环境中,这可能有助于指导未来的儿童生存策略。
