A qualitative study of exploring the therapeutic components of traditional Chinese medicine as a complex intervention through grounded theory

Abstract

To explore and identify the therapeutic components of traditional Chinese medicine (TCM) as a complex intervention through grounded theory, and the correlation and interaction within this model and the possible effects that they may have on the therapeutic effects of TCM. Data were collected through 41 half-day participant observations and 7 in-depth interviews, and the study design and data analysis were based on the grounded theory. The components of TCM practice that emerged were: prescribed Chinese medicinal herbs, doctor's medical advice, psychological intervention, doctor-patient relationship, and patient adherence. There were some overlaps in the TCM diagnosis and treatment process, and there were underlying therapeutic effects associated with diagnosis. TCM herbal intervention was considered as a main therapeutic component which might dominate patients' outcome. We summarized this process as a process of problem finding and solving from macroscopic and microcosmic perspectives, which embodies the concept of a holistic approach and highly individualized pattern through syndrome differentiation and treatment. TCM is a complex whole system, and all therapeutic components of TCM may contribute to global treatment effect. In the future, we need more participants to test and improve the model of grounded theory through qualitative and quantitative methods such as randomized controlled trials so as to identify and explore the relevance of each therapeutic component of TCM with the treatment effect.
