借鉴Delphi法对中医专家舌色诊断经验的拟合研究

Fitting Study on Chinese Medical Specialist's Diagnosis of Tongue Color by Delphi Evaluation

目的对中医专家舌色诊断经验进行拟合研究。方法使用标准化舌象采集环境获取临床舌象,借鉴Delphi方法,邀请中医专家对舌色分类和舌色诊断进行4轮咨询,并借助舌色红绿蓝(RGB)分量的比较从侧面进行验证。结果通过4轮的专家咨询,最后将舌色分为淡白、淡红、红、绛、淡紫、紫、青紫和紫红8类;采集的1255幅舌图像中1072幅(87.0%)获得了一致的判别结果;不同舌色的RGB分量差异有显著性意义(P<0.05或P<0.01)。结论Delphi法是一种较好的拟合中医专家舌诊经验的方法。
