Crit Care Med:新型无创传感器测量ICU患者的移动性!

2017-04-10 xing.T MedSci原创

由此可见,无创性移动传感器是一种新的和可行的方法,来自动评估ICU病人的移动性。

近日,危重病医学领域权威杂志Critical Care Medicine上发表了一篇研究文章,研究人员开发和验证一种无创性的移动传感器可以自动和连续监测ICU患者的移动性。

该研究是在一所教学医院的外科ICU内进行的前瞻性、观察性研究。研究人员对8个患者进行了362个小时的传感器颜色和深度图像数据记录,并且划分成109片段,每个片段包含1000个图像。

研究人员将3个微软Kinect传感器(微软、北京、中国)部署在一个ICU病房内来收集患者连续移动数据。研究人员开发了一个软件能够自动分析传感器数据来衡量ICU患者流动性。为了描述最高的移动性水平,一个验证的11分移动量表被分解为四大类:在床上没有活动、在床上活动、下床活动、步行。

在109个传感器片段中,其中26个来自于3个ICU患者以开发无创性移动传感器,另外83个剩余片段来自于5个不同的ICU患者进行验证。3名医生注明每个片段的最高移动性水平。无创性移动传感器自动输出结果与医生人工标注之间的一致性加权Kappa(κ)统计值为0.86(95%可信区间为0.72-1)。分歧主要发生在“在床上没有活动”与“在床上活动”的分类中,因为“传感器是连续地评估活动”,这比医生使用离散的人工量表来注释对活动更加敏感。

由此可见,无创性移动传感器是一种新的和可行的方法,来自动评估ICU病人的移动性。
