High-quality randomized controlled trials can balance between-group confounding factors and are an important source of comprehensive information on benefits and harms. The CONSORT (consolidated standards of reporting trials) working group released the CONSORT Harms 2022 statement to further improve the harm reporting quality in randomized controlled trials. Traditional Chinese medicine formulas have unique characteristics such as compatibility taboos and using toxic herbs. The harms of traditional Chinese medicine formulas need to be reported in a standard. This study suggests that researchers should pay attention to enhancing the professional competence of research teams, developing suitable standards for reporting the harm of traditional Chinese medicine formulas in randomized controlled trials, and incorporating relevant guidelines into journal publication requirements. These efforts are essential for laying the necessary groundwork for the global dissemination and promotion of traditional Chinese medicine.
ObjectiveTo systematically review the difference in 30-day readmission rates among acute heart failure patients between real-world studies vs. randomized controlled trials (RCTs). MethodsPubMed, EMbase, The Cochrane Library, CNKI, CBM, VIP and WanFang Data databases were electronically searched to collect clinical studies on 30-day readmission rates in patients with acute heart failure from inception to April 12th, 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 16.0 software. ResultsA total of 33 real-world studies and 11 RCTs involving 106 722 subjects were included. The results of meta-analysis showed that the 30-day heart failure-related readmission rates in the real-world studies and RCTs were 10.8% (95%CI 9.3% to 12.3%) and 6.9% (95%CI 5.3% to 8.4%), respectively. The 30-day all-cause readmission rates in real-world studies and randomized controlled studies were 18.6% (95%CI 15.7% to 21.4%) and 14.2% (95%CI 12.0% to 16.3%), respectively. There were statistically significant differences between two kinds of studies (P<0.05). ConclusionsCurrent evidence suggests that the 30-day heart failure-related and all-cause readmission rates in patients of acute heart failure in real-world studies are significantly higher than those in patients of RCTs. Due to the limited quality and quantity of included studies, more high-quality studies are required to verify the above conclusions.
ObjectivesWith the increasing number of core outcome sets (COS) in traditional Chinese medicine (TCM), some problems gradually emerged, which may affect the popularization and application of COS. This paper analyzes the COS research status in the field of TCM based on registry and literature databases, so that researchers may pay attention to it. Methods Registry platforms and literature databases of Chinese and English were both searched from inception to June, 2022. Qualitative analysis was used to analyze the research status of COS. ResultsSeventy-two COS studies were identified from registry platforms, and the results showed some problems, such as uneven disease distribution, insufficient attention to TCM characteristics, unclear COS scope, and insufficient patient and public participation. Ninety-nine studies were identified from different databases, only 7.07% (7/99) of the studies were COS results, and few of them were cited by clinical trials and/or systematic reviews. ConclusionThe authors proposed that standardizing the registration of COS in the field of TCM, improving the methodology of COS studies, expanding the application settings of COS, and strengthening the cooperation of different stakeholder groups are important to ameliorate sustainable development of COS.
Precision medicine is a personalized medical system based on patients' individual biological information, clinical symptoms and signs, forming a new clinical research model and medical practice path. The basic idea of traditional Chinese medicine and the concept of precision medicine share many similarities. The basket trial developed for precision medicine is also suitable for clinical trials and evaluation of the efficacy of traditional Chinese medicine syndrome differentiation and treatment systems. Basket trials are used to evaluate the efficacy of a drug in the treatment of multiple diseases or disease subtypes. It has the advantages of sharing a master protocol, unifying management of subsidiary studies, simplifying the test implementation process, unifying statistical analysis, saving resources, reducing budgets and accelerating the drug evaluation progress. This is similar to the concept of using the "same treatment for different diseases" found in traditional Chinese medicine. This paper introduced the concept and method of basket trials and explored their application and advantages in clinical research into traditional Chinese medicine. This study is expected to provide references for the methodological innovation of clinical research into traditional Chinese medicine.
