目的:借助循证医学的方法为1例急性痛风性关节炎患者制定循证治疗方案。方法:在充分评估患者的情况后,提出临床问题,检索Medline(1990年1月-2009年10月)、Cochrane图书馆(2009年第3期)及CBMWeb(1990年1月-2009年10月)。检索主...目的:借助循证医学的方法为1例急性痛风性关节炎患者制定循证治疗方案。方法:在充分评估患者的情况后,提出临床问题,检索Medline(1990年1月-2009年10月)、Cochrane图书馆(2009年第3期)及CBMWeb(1990年1月-2009年10月)。检索主题词:中西医结合疗法(TCM-WMtherapy);急性(acute);痛风性关节炎(Gouty arthritis);治疗(treat ment ORtherapy);随机对照试验(RCT);Meta-分析(Meta-analysis);系统评价(systematic review);人类(human)。结果:检索发现,关于急性痛风型关节炎132篇RCT,0篇SR,通过分析检索结果、结合临床经验及患者实际情况,为患者制定了循证治疗方案。通过半年随访证实,该方案适合患者。结论:对急性痛风性关节炎患者,采用循证治疗的方法,可有效提高治疗效果,改善患者的预后。展开更多
文摘数据管理是临床研究质量控制的关键环节,数据管理计划(data management plan,DMP)对于每一项临床研究都是不可或缺的,它为数据管理工作提供全面的指导,使各部门工作遵循良好的临床研究数据管理规范,同时DMP也是稽查人员对数据管理部门必须稽查的文件之一。因此,撰写一份符合本机构实际情况的,高质量的DMP十分重要。本文从制定DMP的意义、临床研究数据管理规范对于制定DMP的最低标准和最佳措施、基于电子数据获取(electronic data capture,EDC)的临床研究DMP的制定、制定DMP的关键因素等几个方面进行探讨。最后针对在中医临床研究中使用EDC系统存在的问题进行分析,并提出改进的建议。
