Evidence-based Chinese medicine (EBCM) is one of the innovative achievements in the development of evidence-based medicine (EBM) in China. The EBCM has made initial progress: the evidence-based scientific decision-making model has become popular; a series of key technologies for evidence-based evaluation and research of traditional Chinese medicine (TCM) have been established; several technical specifications have been formulated in line with international standards; clinical evidence database of TCM has been established; a number of high quality clinical trials have been published in internationally renowned journals; and the International Forum on Evidence based Chinese Medicine(EBCM) has become a brand conference. Difficulties in EBCM development mainly involve: lack of high quality clinical evidence, difficulty in producing evidence, and decentralization of research team. Based on opportunities and challenges of the development of TCM, this article proposed the short-term and long-term goals, implementation paths and five key directions for the development of EBCM in the future, and puts forward three suggestions for further development of EBCM.
Using Chinese Materia Medica (CM) as injections is an innovation that is proving effective in extensive clinical use in Mainland China. However, recent reports have focused on adverse reactions, ignoring the considerable successes of these preparations. In order to achieve balance in the media and in the minds of the public, we suggest the first step is to clarify the concepts of and differences between adverse drug reactions (ADR) and adverse events (AE) for all concerned—the public, medical practitioners, government officials, and lawmakers. Second, the State Food and Drug Administration should raise the requirements for Chinese Medicine Injection (CMI) registration and license approval and emphasize the importance of evidence-based CMI development and evidence-based CMI license approval. Thirdly, drug companies and institutions should reinforce basic research about the quality control of herbs and CMI-drug interactions. Fourth, the Government should clarify the legal responsibilities for CMI approval agencies, CMI developers, medical doctors, and patients. Fifth, the medical association and Government should enhance training for health care professionals concerning the usage of CMIs. And finally sixth, State Food and Drug Administration should monitor the content and quality of the directions for use of CMI.
Objectives To systematically evaluate the clinical characteristics of adverse drug reactions (ADRs) caused by Shuanghuanglian Injection (SHLI) and to provide reference for post-market evaluation and clinical application of SHLI. Methods We searched electronic databases such as the Chinese National Knowledge Infrastructure (CNKI, 1979.1-2009.9), the Chinese Science and Technology Journal Full-text Database (VIP, 1989.1-2009.9), and the Chinese Biomedical Disc (CBMdisc, 1978.1-2009.9). ADR cases were analyzed according to occurrences categorized. Available data was assessed using the Chi-square test including relative ratios (RR) with 95% confidence intervals (95%CI). Different medicine combinations and comparisons between SHL powder injection and SHL injection were calculated using the statistical software Stata 9.1. Results (1) A total of 452 articles were included with a total of 2 799 ADR cases reported. Case reports were the main design type of included literature, which accounted for 84.51%. According to 31165 cases of SHLI treatment and 1 013 corresponding ADRs, the incidence of SHLI ADR was calculated as 3.25%. (2) The ratio of male to female in the reported ADR cases was 1.13׃1. (3) Allergy to Penicillin, which accounted for 13.38% of the total cases, was at the top for past allergic history, followed by sulfonamides and asthma (2.68%). (4) In terms of disease treated respiratory disease accounted for 91.75% of all cases of SHLI ADRs, followed by digestive diseases (5.17%), and urinary diseases (1.11%). (5) Penicillins were the most common combination choice with SHLI, and such combination showed higher ADR risk than SHLI used alone [RR=3.14, 95%CI (2.58, 3.81)]. (6) Multiple systems/organs were involved in SHLI ADRs, and were ranked downwards according to proportion as: skin, digestive system, general reactions, respiratory system, nervous system, cardiovascular system, local reactions, urinary system, hematologic system and others. (7) According to the WHO ADR Classification Criteria, ADR cases were divided into four grades. There were 6.36%, 5.48%, 45.62%, and 2.12% cases of Grade Ⅰ, Ⅱ, Ⅲ and Ⅳ , respectively. And the prognoses of the rest 52.42% cases were reported unclearly. (8) All cases of death were caused by allergic shock, except for one, which was caused by myocardial infarction induced by pain at the injection site. The fastest ADR case occurred 1 minute after being injected. (9) There was a remarkable difference (Plt;0.05) in the rate of ADR caused by SHLI in power form (2.25%) and as a solution (4.14%). Conclusion The clinical manifestations of ADRs caused by SHLI mainly include skin allergic reactions and gastrointestinal reactions. There is an increased risk of ADR induced by combined uses of SHLI and other drugs, especially antibiotics. Compared to the solution, the powder has lower ADR occurrence and higher safety with statistical significance. We propose strengthening management and surveillance on SHLI from manufacturing to application, and improving the level of the risk management for post-market drugs.
To aim directly at the individualized character and tendency about clinical assessment of Traditional Chinese Medicine (TCM), we draw off a new pathway which is evidence-based goal attainment scale(EBGAS) in the text. i.e., we will develop clinical individualized assessment method of TCM on account of GAS by the approach of evidence based medicine.
Inconsistency, impracticability and non-standardization of the selection, measurement and reporting of outcomes are three primary existing issues in clinical trials. These problems pose a threat to huge research waste when the results of similar studies are not able to be combined or compared. The key for resolution will be to standardize outcomes in traditional Chinese medicine (TCM) clinical trials and to establish a core outcome set (COS), which is a set of outcomes to be reported as a minimum in all TCM clinical trials of similar healthcare system and syndromes. The first step in the development of COS is to collect all existing outcomes, that is, to build a pool of outcomes for clinical trials of TCM. A pool of outcome is the basis of developing COS, which is important to follow strict and scientific methodology. This paper aims to construct an outcome pool from published literature, clinical trial registration protocols, and clinicians, and patients questionnaires were used to form a list of outcomes. In addition, the influencing factors of constructing an outcome pool and considerations for each problem are summarized in order to provide guidance and reference for the development of COS in clinical trials for TCM.
