互联网医院危急患儿识别系统的构建及检测

目的构建基于儿科评估三角的互联网医院危急患儿识别系统,并评价系统评估准确性。方法按照系统开发程序构建基于儿科评估三角的互联网医院危急患儿识别系统。收集40个标准化案例,由4名互联网医院儿科医务人员应用系统判断患儿病情,采用模拟评估法评价系统的信度。由2名儿科分诊护士线下应用儿科评估三角及15名互联网医院儿科医务人员应用系统对644例患儿进行病情评估,采用诊断性试验评价系统评估准确性。结果系统4名评定者间信度ICC为0.665,重测信度为0.527~0.899(均P<0.05)。应用该系统对儿科评估三角中外观、呼吸、循环、识别危急患儿的灵敏度分别为70.0%、86.7%、50.0%、80.0%,特异度分别为79.3%、93.6%、99.7%、73.5%,约登指数分别为0.493、0.803、0.497、0.535(均P<0.05)。结论基于儿科评估三角的互联网医院危急患儿识别系统识别危急患儿的一致性、稳定性及准确性尚可,具有一定的临床价值。
