一、CONSORT-中药复方背景
传统中医药学(Traditional Chinese Medicine, TCM)是历史最悠久的具备独特和完整理论的医学体系之一,在我国医疗体系中拥有重要的地位,且越来越受到国际上关注。中药复方(Chinese Herbal Medicine formulas, CHM Formulas)是TCM临床治疗最主要的形式。目前已有数万篇与中药复方相关的临床试验报告发表,但其报告质量并不理想。这不仅降低了人们对中医药的价值的认识,影响了读者或审稿专家对其疗效和安全性的判断,也易引起各界对中医药的怀疑和批评。因此,中医药学临床专家、方法学家、流行病学家和医学期刊编辑组的共同协作完成了CONSORT–中药复方(以前称中医药临床随机对照试验报告规范,CONSORT for TCM)的制定。
2007年,CONSORT–中药复方初稿以中、英文形式同时发表并公开征求意见,包括1张含有22项条目的清单和1张流程图。2012年底,结合CONSORT 2010声明和各方反馈的意见和建议,工作组执行委员深入讨论并修订了CONSORT-中药复方的相关内容。2013年6月,执行委员将修改内容整理后分发给全部工作组成员并征求反馈意见,最后于2016年底完成了CONSORT-中药复方的修订。 CONSORT–中药复方2017是在 CONSORT 2010 声明的基础上,结合TCM中“证”的概念和中药复方特点形成的报告规范。清单新增了1项子条目“关键词”(条目1c),且对文题和摘要(条目1a和1b)、背景和目的(条目2a和2b)、受试者(条目4a)、干预措施(条目5)、结局指标(条目6a)、可推广性(条目21)和解释(条目22)等7项条目进行了补充或修订,另依据中药复方的特点对“危害”(条目19)的解释重新进行了阐述。此扩展版也结合了“干预措施的描述和重复的框架”的具体内容(Template for Intervention Description and Replication, TIDieR)。

三、CONSORT-中药复方使用注意事项
中药复方随机对照试验在设计时,为了更好地了解此类试验设计、实施和分析中的注意事项,建议参考CONSORT-中药复方;投稿时,根据需要或要求可将CONSORT-中药复方清单(checklist)作为投稿材料之一递交,并引用已发表的相关报告规范文献。审稿人也可根据编辑部要求参照CONSORT-中药复方标准和作者提供的清单来审稿。一般CONSORT声明的注意事项和局限性同样适用于本扩展版声明。CONSORT-中药复方流程图仍然沿用CONSORT 2010标准版,未作任何修改。
CONSORT-中药复方并不适用于草药和针刺试验的临床试验报告,因为后者未涉及TCM中理、法、方、药的内容。草药临床试验报告可参考草药干预随机对照实验(herbal medicine interventions randomized control trials, HRCT)报告的统一标准(consolidated standards of reporting trials,CONSORT)扩展版——概述。
注:本文内容是参考相关文献后对中药复方临床试验报告的统一标准(CONSORT for Chinese Herbal Medicine formulas, CONSORT - CHM Formulas)的概述。关于CONSORT-中药复方的更多内容详见官方网站(http://www.consort-statement.org)或论文CONSORT Extension for Chinese Herbal Medicine Formulas 2017: Recommendations, Explanation, and Elaboration (https://pubmed.ncbi.nlm.nih.gov/28654957/)、CONSORT Extension for Chinese Herbal Medicine Formulas 2017: Recommendations, Explanation, and Elaboration (Simplified Chinese Version) (https://pubmed.ncbi.nlm.nih.gov/28654957)
