代谢综合征痰瘀互结证量化诊断标准的研究

Study on Quantitative Diagnostic Criteria of Phlegm-stasis Interjunction Syndrome of Metabolic Syndrome

目的确定代谢综合征痰瘀互结证量化诊断标准。方法基于文献研究制定《基于层次分析法的MS痰瘀互结证专家咨询问卷》,邀请专家填写问卷,采用专家群决策算法构建《MS痰瘀互结证诊断标准(草案)》。前瞻性收集MS患者,采用条件概率换算法、最大似然判别法对MS痰瘀互结证诊断标准进行临床验证并修订,制定MS痰瘀互结证量化诊断标准。结果建立的MS痰瘀互结证量化诊断标准诊断效能灵敏度95.7%,特异度84.0%,准确度91.6%,阳性似然比5.98,阴性似然比19.46。结论基于文献研究、专家咨询法及诊断性试验建立的MS痰瘀互结证量化诊断标准具有较好的诊断效能。

Objective To determine the quantitative diagnostic criteria of phlegm-stasis interjunction syndrome of metabolic syndrome.Methods Based on the literature research,the Expert Consultation Questionnaire for MS Syndrome of Phlegm-stasis Interjunction based on Analytic Hierarchy Process was developed.Experts were invited to fill out the questionnaire,and the Diagnostic Criteria for MS Syndrome of Phlegm-stasis Interjunction(Draft)was constructed by using the expert group decision algorithm.The patients with MS were prospectively collected,and the diagnostic criteria for phlegm-stasis interjunction syndrome of MS were validated and revised by conditional probability conversion method and maximum likelihood discrimination,and the quantitative diagnostic criteria for phlegm-stasis interjunction syndrome of MS were finally formulated.Results The sensitivity,specificity and accuracy of the established quantitative diagnostic criteria for MS phlegm-stasis interjunction syndrome were 95.7%,84.0%,91.6%,positive likelihood ratio 5.98,negative likelihood ratio 19.46.Conclusion The quantitative diagnostic criteria for MS phlegm-stasis interjunction syndrome established based on literature research,expert consultation and diagnostic tests have good diagnostic efficacy.
