Different from modern medicine, traditional Chinese medicine (TCM) has its unique thought patterns and decision methods. In the process of developing TCM clinical practice guidelines, not only the modern clinical researches should be included, but also the TCM ancient books which had influenced TCM for thousands of years should be included. As an important carrier of TCM, the characteristics of researches in TCM ancient books are different from modern clinical researches. In this paper, we introduced the present situation of the TCM guidelines and how to use TCM ancient books for developing TCM clinical guideline with the guidance of evidence-based method. We used the example of developing of headache TCM guideline to explain how to use TCM ancient books as evidence source for guideline development and explored the application of evidence-based research of TCM ancient books to promote TCM clinical guidelines development.
Objective To review the current status of evidence-base medicine (EBM) research on traditional medicine in Japan. Methods Serial reports of EBM special committee of Japan Society for Oriental Medicine (JSOM) were reviewed. Results EBM special committee of JSOM was established earlier and carried out systematic reviews of Kampo treatment throughout Japan. The quality of preparations was standardized and reliable. Evidence Reports of Kampo Treatment 2009 (EKAT 2009) may be a promising promotion for Kampo treatment in Japan. Conclusion For the promotion and development of evidence-based Chinese medicine in China, we need to learn from EBM research projects of JSOM. Based on the current status of EBM research in China, special efforts should be made in validity of research data and scientific analysis and reports of non-randomized trials. According to the characteristics of traditional Chinese medicine, EBM research should be systematically carried out from simple to complex.
Objective To evaluate quality and current status of traditional Chinese medicine (TCM) guidelines and consensus, and to promote the improvements in the quality of guidelines and consensus. Methods A systematic collection of TCM guidelines and consensus published in medical journals in 2022 was conducted. We used scientific, transparent, and applicable ranking tools (STAR) for evaluation, analyzed the scoring rates (%), and assessed the quality level and influencing factors of guidelines and consensus through methods such as comparison and stratification. Results A total of 130 TCM guidelines and consensus were included. Guideline areas with higher scores included recommendations (65.3%), evidence (55.9%), and guideline development groups (54.2%). In the case of consensus, higher scores were observed in recommendations (38.7%), guideline development groups (37.0%), and funding (30.0%). The total score rate of TCM guidelines exceeded that of national guidelines, while the consensus rate was lower. Stratified analysis revealed statistical differences in guideline score rates among journals and issuing institutions, as well as significant differences in consensus score rates among journals, formulation institutions, subjects, and funding categories. Conclusion The quantity and quality of TCM guidelines and consensus are on a positive trajectory, with higher quality levels in guidelines than in consensus. The overall quality of TCM guidelines surpasses that of national guidelines, particularly emphasizing the scientificity of guideline formulation. However, the overall quality of consensus remains lower than that of the national consensus. Factors such as journals, formulation institutions, subjects, and funding categories are identified as potential influences on the quality of TCM guidelines and consensus.
ObjectivesTo systematically review the safety of traditional Chinese medicine injection based on clinical centralized monitoring studies that have been carried out and listed so far, to understand basic situation of adverse reactions and explore the risk factors of traditional Chinese medicine injections and to provide evidence for clinical rational use of drugs and optimizing centralized monitoring methods. MethodsCFDA, CNKI, VIP, WanFang Data, Sinomed, PubMed and The Cochrane Library databases were electronically searched to collect studies on safety monitoring of listed traditional Chinese medicine injections from inception to February, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by using Excel software. ResultsA total of 14 studies involving 14 varieties of injections, 296 200 cases were included. The highest incidence rate of adverse reactions was found in the XueBiJing injection (2.54%). The related factors of ADR extraction were age, sex, drug combined usage, time from administration, allergic history, administration days, indication, dose and distribution of the tube. ConclusionsThe safety of traditional Chinese medicine injection is generally high. Middle and old age is an important factor in the occurrence of ADR. The incidence of ADR is relatively high in the first 6 days of drug use, and the incidence of ADR is more likely to be caused by irrational use of drugs in clinic, and the history of allergy may be related to the occurrence of ADR. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusion.
Objective To assess the benefits and harms of traditional Chinese medicine in the treatment of postmenopausal osteoporosis. Methods We electronically searched MEDLINE (1966-2003), EMBASE (1974-2003), Controlled Trials Register and The National Research Register, The Cochrane Library Issue 4, 2003, CBM disc, VIP, CNKI, and CMCC. We also handsearched some related journals. The search was conducted in Nov., 2003. The quality of included randomized controlled trials was evaluated and meta-analysis was conducted by RevMan 4.2.2. Results We identified 33 studies including 2 337 patients and 27 traditional Chinese medicines. Some traditional Chinese medicines alone or integrated Chinese and Western medicine may be effective for improving patients’ bone mineral density, serum oestradiol and serum calcium. For example, Compared with placebo, Bushen Yigu soft extraction with WMD 0.76, 95% confidence interval 0.65 to 0.87, Bushen Qianggu capsule with WMD 39.94, 95% confidence interval 35.12 to 44.76 were effective for improving the level of serum oestradiol.There were no confirmed results of the other traditional Chinese medicines because of the small number of studies or inconsistent conclusions among studies. We didn’t find obvious side effects. Conclusions Some traditional Chinese medicines may be effective for treating postmenopausal osteoporosis. Due to the limited evidence identified, we can not draw a firm conclusion. More randomised controlled trials of high quality are needed for ber evidence.
Objective To assess the quality of reporting of randomized controlled trials (RCTs) related to traditional Chinese medicine (TCM) published in the Chinese Journal of Evidence-Based Medicine by CONSORT statement and Jadad scale. Methods We handsearched the Chinese Journal of Evidence-Based Medicine to identify TCM RCTs. The revised CONSORT statement and Jadad scale combined with self-established criteria were applied. Results A total of 57 RCTs were identified of which there were 17 TCM RCTs. Some items in CONSORT checklist were completely reported in all TCM RCTs, such as abstract, inclusion and exclusion criteria, intervention, randomization sequence generation, description of statistic method, description of baseline data, outcomes and estimation, and explain results. Compared with the previous findings, there were more trials in this study to report allocation concealment, randomization implementation, use of flow chart and appliance. Only 3 RCTs (17.6%) reported acknowledgements. One RCT did not describe syndrome type of TCM, and 4 RCTs (23.5%) carried out dummy. The mean Jadad score was 4.35±1.11 in all trials, of which 11 RCTs (64.7) ranked 5 points. Conclusion The comprehensive quality of reporting of TCM RCTs published in the Chinese Journal of Evidence-Based Medicine from 2001 to 2008 has been improved. After the publication of CONSORT statement and CONSORT for traditional Chinese medicine, the quality of reporting of TCM RCTs is improved. We are looking forward to improving the CONSORT for TCM.
In the process of evidence-based practice, the evaluation of evidence applicability relied on the subjective judgment of clinicians, while the systematic method of which was still in lack. The complex clinical information of traditional Chinese medicine (TCM) enhanced the uncertainty and risk of applying evidence. Based on the analysis of the process of evidence-based practice, this paper introduced the method of TCM evidence applicability evaluation and used the raw data of clinical trials to develop a clinical prediction model to enable the assessment of the evidence applicability on individual patients. The establishment of individual evidence applicability evaluation method could promote the rational application of TCM evidence in the long term.
Master protocol with adaptive design is a new complex innovative trial design that combines an adaptive treatment strategy and master protocol. It is more flexible and adjustable. In the complex clinical trial environment, the dynamics emphasized in this design are consistent with the idea of traditional Chinese medicine (TCM) syndrome differentiation and treatment. In this study, we summarized its concept, characteristics and advantages, and we also discussed its application in TCM clinical research. We hope this paper can provide more thinking and suggestions for TCM clinical trials.
ObjectiveTo systematically review the researches on grading criteria for quality of evidence and strength of recommendations of traditional Chinese medicine (TCM). MethodsPubMed, EMbase, Web of Science, CNKI, WanFang Data and VIP databases were electronically searched to collect researches on grading criteria for quality of evidence and strength of recommendations of traditional Chinese medicine from inception to June 2021. Two reviewers independently screened literature, extracted data; and then, descriptive analysis was performed using qualitative methods. ResultsA total of 18 studies were included. Specifically, 8 studies presented both the level of evidence and the strength of recommendations, 9 presented the level of evidence, and 1 presented the strength of recommendations. Thirteen studies considered both TCM evidence and modern medical evidence sources, 3 included only evidence from ancient literature, 1 focused only on post-marketing safety evaluation of Chinese medicine, and 1 focused only on real-world studies of TCM. ConclusionCurrently, there are numerous criteria for TCM related quality of evidence and strength of recommendations, and some are developed only for TCM characteristic evidence. Most researchers of TCM guidelines expect to fully value the significance of ancient literature and expert experience or opinion in guideline development.
