Data management system is a major factor affecting the quality of clinical trial. Development of data management system include a steering group and data safety and monitoring board, data collection, database, performance of the data safety and monitoring, as well as locking of database. This article provides key issues of the five parts so as to help researchers understand the clinical trial data management system.
The two factors that affect enrollment of participants and the process of intervention in randomizedcontrolled pragmatic trials are similar to the situation of clinical practice, thus its effects are similar to the situation ofclinical practice. Therefore, when one estimates an intervention’s effect on a patient, it will be more similar to a real clinicalsituation than results taken from an explanatory trial. Due to the introduction of interventions and process variables usedin a pragmatic trial that conform to traditional Chinese medicine and acupuncture practices, more and more interest isgrowing among researchers in the traditional Chinese medicine field. This article introduces the principles and conceptsof the pragmatic trial, and the key points of design via some samples.
Clinical trial transparency, include clinical trial registration, unbiased reporting results and sharing individual participant data (IPD), is one of the most important revolutionary concepts following clinical epidemiology and evidence-based medicine in the medical field. Sharing IPD is a medical ethics issue reflected a new sense of worth and constructing new rules of clinical trials. Our viewpoint is that from the essential purpose of clinical research, IPD is a social public property. Sharing IPD is a one of the best ways for respecting the contributions of the participants, and one of the keys for changing face of clinical trials.
若在已发表的报告中干预措施描述不完整，临床工作者和患者就无法可靠地实施有效的干预措施，其他研究人员也无法在此研究基础上重复或进一步开展研究。然而，已发表文章中干预措施的报告质量非常差。为提高报告的完整性并最终提高干预措施的可重复性，一个国际专家组和利益相关方共同制订了描述干预措施的清单和报告规范（Template for Intervention Description and Replication，TIDieR）。制订过程包括：相关清单和研究的文献综述，针对国际专家小组的德尔菲调查以指导选择清单条目及召开面对面的小组会议。最终确定的 12 条 TIDieR 清单条目（包括：干预措施简称、实施理由、实施资料、实施过程、干预措施实施者、实施方法、实施地点、实施时间及强度、个性化方案、方案更改、预期效果和实际效果）是对 CONSORT（The Consolidated Standards of Reporting Trials）2010 声明中条目 5 和 SPIRIT（Standard Protocol Items: Recommendations for Interventional Trials）2013 声明中条目 11 的扩展。虽然该清单强调的是试验中干预措施描述，但该指导仍适用于所有评价性研究设计。本文对 TIDieR 清单的每个条目进行了解释和说明并呈现了高质量报告的实例。TIDieR 清单和报告规范可提高干预措施的报告质量，并且使得作者对干预措施的描述、审稿人和编辑对有关干预措施描述的评估、读者对干预措施的使用更加容易。
With the encouragement of national policy on drug and medical device innovation, multi-center clinical trials and multi-regional clinical trials are facing an unprecedented opportunity in China. Trials with a multi-center design are far more common at present than before. However, it should be recognized there still exists shortcomings in current multi-center trials. In this paper, we summarize the problems and challenges and provide corresponding resolutions with the aim to reduce heterogeneity between study centers and avoid excessive center effects in treatment. It is urgent to develop design, implementation and reporting guidelines to improve the overall quality of multi-center clinical trials.
The concept of clinical trial transparency has been promoted for more than 40 years. The act of clinical trial registration, report guidelines development, and data sharing has has been strongly pushed forward and become a common practice. The clinical trial process being the key procedure of trial operation and quality control, determines the accuracy of the results. However, the process report of clinical trials is insufficient. In this article, we summarize the importance of clinical trial process report and provide corresponding suggestions. We propose that medical journals, reporting guidelines developers and clinical trial registration platforms should work together to strengthen the process report of clinical trials and promote full transparency of clinical trials.
在临床干预试验中，运用随机分配是对照试验中控制偏倚和混杂的最佳工具。研究人员必须确保在试验报告中包含读者所需要的信息，以判断结果的有效性及其意义。事实上，完整的试验报告可让临床医生改进他们的临床实践，以反映当前最佳证据，并改善患者临床终点。制定 CONSORT 声明可协助研究人员、作者、审稿人及编辑了解临床试验报告中所需的必要信息。CONSORT 声明适用于任何干预措施，包括草药产品。当前草药干预措施的对照试验未充分报告 CONSORT 建议的信息条目。我们希望最近制定的 CONSORT 建议条目扩展版能更准确地报告草药干预措施随机对照试验，使其更加完整。我们编写的这份解释性文件除概述了每项建议的理由外，还提供了 CONSORT 条目和相关详细说明，并为每项建议提供了良好报告和经验证据的范例，以帮助作者能更好地运用它们。随着越来越多的证据积累和反馈意见的收集，这些有关草药产品临床试验报告的建议可随时进行修订。
Evidence produced by clinical trial is the main basis for health care decision-making at all levels. In recent years, some problems been revealed in the national data audit of new drug clinical trials have sounded the alarm for the quality of clinical research in China. In addition to strengthening the implementation of clinical trial process management and supervision, we call attention to the coherence and consistency of trial design and implementation, including the promotion of clinical trial design in the agenda of improving the quality of the trials and putting forward reasonable suggestions. We hope that our work could make research ideas clear from the source of a clinical trial, with a view to avoid violating protocol behavior and provide standardized recommendations for improving the quality of clinical trials in China.
