AANS 2014:数据库统计的腰椎融合手术不准确

一项最新研究显示,针对腰椎融合手术,管理数据库的代码和外科医生的诊断之间存在差异,该研究作为一篇摘要,于2014 年 4 月 8 日发表在美国神经外科医师协会(AANS)第 82 届年度会议上。最近从国家管理数据库采集到的统计数字表明腰椎融合手术在上升,其中增幅最大的发生在那些诊断为椎间盘突出或椎间盘退行性疾病的患者。

然而,外科医生声称,这两者中任意一者都不是一个广泛接受的手术指征。那么,这些数据库如何做,才能准确地捕获外科医生的融合手术指征?Yakov Gologorsky博士领导的一个研究团队侧重于统计全国范围内住院病人样本 (NIS),使用第9版临床修正国际疾病分类法(ICD-9-CM)排除代码对病例分类——该代码不是由外科医生,而是由医院医疗编码分配。


全国范围内住院病人样本数据库不能准确地反映融合手术的手术指征,该研究团队报告说,外科医生的诊断和排除代码之间存在重大的差异。今天,在第 82届美国神经外科医师协会 (AANS) 科学年会期间,Gologorsky博士提交了该研究小组的研究发现。研究人员审查了一个跨越两年的时期内开展的170例腰椎融合手术,比较了外科医生的诊断与提交到NIS的主要的 ICD-9-CM代码。

59%的病例,主要的 ICD-9-CM诊断与外科医生的诊断相匹配。对于那些纳入研究的 170例手术病例,其中43例涉及公认的指证,如创伤、 肿瘤、 或感染,其余 127例为退行性疾病。排除这43例符合公认手术指征的手术病例,该研究团队发现,这一时期主要的 ICD-9-CM诊断与外科医生的诊断只有45%匹配。

该团队发现,从管理数据库中提取的、基于 ICD-9-CM代码描述的此类手术的手术指征,并不能准确地反映外科医生的手术指征。虽然此类数据库可能准确地描述全国腰椎融合手术的比例,但是源代码中保真度的缺乏限制了他们准确地识别手术指征的能力。该研究报告的共同作者包括三位加拿大皇家学会会员:John Knightly博士、John Chi博士和Michael W. Groff博士。作者报告没有利益的冲突。
