中医证候量化的临床流行病学研究初探

A Clinical Epidemiological Study on Quantitative Diagnosis of TCM Syndrome

辨证施治是中医学之精华所在,现行的辨证标准的建立大多基于专家经验或直观观察,缺乏精确的量化,从而影响了辨证的准确性,难以适应现代中医药研究与临床的要求。建立在群体调查基础上的临床流行病学方法,通过对患病人群中症状、体征或有关指标的频数分布及相应的统计分析,是中医证候定量化的重要手段。本文结合我们进行的有关研究课题,从调查项目的选择、软指标的记分、合格调查群体的确立,项目初步筛选的方法及有关的统计分析方法,对此进行了初步探讨。

Treatment based on syndrome differentiation is the essence of traditional Chinese medicine. However, most of diagnostic criteria of TCM syndrome are ostablished on the basis of intuitive and empirical observation which is lack of rigorous quantitative approaches, so the accuracy of syndrome differentiation is affected. The purpose of this study is to discuss the establishment of approaches of quantitative diagnosis by employing clinical epidemiological methods including choice of survey items, scoring of soft indices, determination of survey population, screening of survey items and relevant statistical methods.
