JAMA Pediatr:轻度头部创伤和颅内损伤儿童的风险评分

至今为止,治疗轻度创伤性脑损伤(mTBI)和颅内损伤(ICI)儿童的计算层析成像仍不清楚。基于证据的风险评估可以提高患者安全性并减少资源使用。


近期,一项发表在杂志JAMA Pediatr上的研究旨在预测mTBI和ICI儿童需要进行重症监护病房观察的风险。

这项回顾性分析包括自2004年到2006年北美25个急诊部门的患者。研究者们收集了年龄小于18岁的mTBI患者(格拉斯哥昏迷量表[GCS] ,13-15)以及计算机断层扫描检测的ICI患者。

主要结果包括神经外科干预、TBI超过24小时的插管或TBI的死亡。多变量逻辑回归用于预测结果。C统计量用于量化辨别,并且使用10倍交叉验证在内部验证模型性能。基于这种模型,创建了儿童颅内损伤决策辅助评分。

此项研究结果显示:在急诊科,GCS评分13至15分的15162名头部损伤的儿童接受头部计算机断层扫描成像,其中839例(5.5%)患有ICI。有和没有复合结果的中位数年龄分别为7岁和5岁。

在那些患有ICI的患者中,8.7%(n = 73)的患者经历主要结果,包括8.3%(n = 70)的患者经历神经外科手术。与结果显着相关的唯一临床变量是GCS评分(优势比[OR],3.4; 95%CI,1.5-7.4 GCS评分13和15)。

重要的放射学预测指标包括中线移位(OR,6.8; 95%CI,3.4-13.8),颅骨凹陷性骨折(OR,6.5; 95%CI,3.7-11.4)和硬膜外血肿(OR,3.4; 95%CI,1.8 -6.2)。模型C统计量为0.84(95%CI,0.79-0.88); 10倍交叉验证的C统计量为0.83。

基于这种模型,研究者们开发了儿童的颅内损伤决策辅助评分,范围从0分到24分。具有0分(即,这些风险因子中没有一个)的阴性预测值为98.8%(95%CI,97.3%-99.6%)。

此项研究结果得出结论:较低的GCS评分,中线偏移,颅骨凹陷性骨折和硬膜外血肿是mTBI和ICI儿童需要重症监护护理的主要危险因素。基于这些结果,儿童颅内损伤决策辅助评分是一种潜在的新工具,可对该人群进行风险分层,从而有助于管理决策。
