ABSTRACT
The occurrence, development and outcome of most diseases are a complex process. It is the advantage of traditional Chinese medicine to establish complex interventions that are consistent with the characteristics of disease development. The specific steps are as follows: quantitative research on literature research, establishment of interview framework; focus on interviews, specificization of interview outlines; semi-structured interviews, preliminary construction of complex intervention programs; evaluation of efficacy of complex interventions. The introduction of semi-structured interviews and other qualitative research methods into the modernization of traditional Chinese medicine, combined with quantitative methods such as text analysis and data mining, is also helpful in formulating the standard of diagnosis and treatment system with Chinese characteristics.
