Radiology:CT是如何改变急诊的临床决策的

2016-04-18 MedSci MedSci原创

这个前瞻性,多中心,观察研究的目的是判断计算机断层扫描(CT)是如何影响急诊医生的诊断,不明诊断,和临床管理决策的。

这个前瞻性,多中心,观察研究的目的是判断计算机断层扫描(CT)是如何影响急诊医生的诊断,不明诊断,和临床管理决策的。

来自主要的学术医学中心的内科医生在2012年7月到2014年2月接受使用CT前后诊断结果的调查。使用CT的原因有头痛,胸痛和/或呼吸困难,腹痛。调查涉及245个医生的1280名患者。使用CT前后的诊断结果在头痛,胸痛和/或呼吸困难,腹痛的病人中分别发生了24%,42%和51%的改变。

当获取了CT的信息后,诊断可信度明显上升。CT信息同时也改变了患者住院的决定,分别改变了19%, 19%和 25%。作者提到,CT很大程度的影响了急诊医生的诊断,诊断可信度,和住院的决策。

专家观点:

这是一个有趣的研究,试图量化急诊部门使用CT进行诊断和决策制定的功效,这是考虑到了费用增加,射线暴露和扫描相关的偶然发现。

为了弥补证据缺口,作者前瞻性的观察了麻省总医院,曼彻斯特大学,霍普斯金医院,马里兰医院,杜克大学医学中心,北卡罗来纳州医院和华盛顿大学的急诊部门。

这个研究表明,整体上,CT影响了25%-50% 的患者的主要诊断,和20%-25%患者的住院决定。确实存在相当一大部分的患者,在当地医院诊断的结果适用于全国各地的医学中心。

作者提供了此研究的合理的局限总结。这个结果主张CT在急诊部门有主要的功用,但是仍需额外的调查来平衡功效与潜在的低当量CT扫描的风险,射线暴露和花费。
