Design of Retrospective Treatment Outcome Research and Its Application in Traditional Chinese Medicine
Retrospective treatment outcome (RTO) is a kind of observational study that retrospectively collects data about the exposure factors or the interventions over a period of time in certain people who have already had clinical outcomes through questionnaire survey or interview, and analyzes the correlation between exposure factors or interventions and disease outcomes. RTO can initially evaluate the effectiveness and safety of the interventions for the specific group of people, and identify the treatments with the highest association with disease outcomes, thereby providing clues and evidence for subsequent prospective clinical trials. This study systematically introduced the concept, origin and methodological items of RTO, compared the similarities and differences between RTO and other observational studies, described the application status and prospects, advantages and limitations of RTO. It is proposed that future applications of RTO in traditional Chinese medicine (TCM) include such as screening out the Chinese material medica with different prescriptions/ compatibility/ dosage/ preparations/ modes of administration, evaluating the effect of TCM-specific therapies when treating disease before it arises, selecting the varied treatment options for emergent and novel infectious diseases. All these provide methodological references for the application of RTO in conducting TCM researches.
