Lancet:比较GOLD 2007和2011预测慢性阻塞性肺疾病死亡率

2015-05-18 崔倩 译 MedSci原创

背景:慢性阻塞性肺疾病(COPD)的最佳分期系统上没有达成普遍共识。虽然文件(例如,慢性阻塞性肺疾病2007年全球倡议[GOLD])传统上使用1秒用力呼气容积(FEV1)分期,临床参数已被添加到一些准则中(如GOLD 2011),以改善患者管理。作为COPD国际合作评估(3CIA)计划的一部分,该研究的目的是调查患者如何通过GOLD 2007和2011进行了分类,并比较临时文件的死亡率的预测准确性

背景:慢性阻塞性肺疾病(COPD)的最佳分期系统上没有达成普遍共识。虽然文件(例如,慢性阻塞性肺疾病2007年全球倡议[GOLD])传统上使用1秒用力呼气容积(FEV1)分期,临床参数已被添加到一些准则中(如GOLD 2011),以改善患者管理。作为COPD国际合作评估(3CIA)计划的一部分,该研究的目的是调查患者如何通过GOLD 2007和2011进行了分类,并比较临时文件的死亡率的预测准确性。
    
方法:研究人员搜索了从2008年1月1日至2014年12月31日公布的报告。数据来自于GOLD 2007和2011中同意参加并且有最小量信息需要的参与者,研究人员做了一个基于患者的现有数据的荟萃分析。使用原始数据,研究人员重新计算所有参与者接受GOLD 2007 I-IV类,黄金GOLD 2011 A-D阶段。研究人员用生存分析,C统计和非参数回归模型的时间到死亡的数据,并比较GOLD 2007和GOLD 2011分期系统预测的死亡率。
    
发现:研究人员从7个国家的22个COPD群组研究收集了15632例个人数据,共计70184人年。患者平均年龄为63.9岁(SD 10.1);其中,10751例(69%)为男性。基于单独的FEV1(GOLD 2007),2424(16%)例患者有轻度(Ⅰ)疾病,7142例(46%)是中等(Ⅱ),4346例(28%)是重度(III),1670例(11%)有极重度(IV)疾病。我们比较分期与金2007文档与新GOLD2011系统的14660例患者:5548例(38%)为A级,2733例(19%)为B级,1835例(13%)为C级,4544 例(31%)为D级。GOLD 2011将整体COPD严重分配到更严重的类别。在D期的患者是以前IV期的患者的近三倍(P<0.05)。对于这两个系统,该预测能力生存可显著长达10年(P<0.01),但曲线下的面积只有0.623(GOLD 2007)和0.634(GOLD 2011),GOLD 2007和GOLD 2011没有显著差异。研究人员确定了85%,55%和35%预测的FEV1阈值,为了更好暂存死亡率的COPD严重性,其类似于先前使用的那些。
    
结论:GOLD COPD分类方案用于临床的风险分类时,在个人层面上预测3年的随访及更长时间的总死亡率,有足够的区分能力。由于GOLD 2011重新分类不知道是否可以改善健康结果,所以需要增加COPD患者的治疗力度。探索当前和新的COPD多元指数的预测能力时,以证据为基础的阈值应被探求。
