Radiology:医疗保险和商业保险人群之间诊断成像使用率的比较:为什么重要?

近几年,无创诊断成像(NDI)诊断成像是医疗保险参保者中增长最快的项目之一,使用率趋势逐年增高。由于数据的可用性和可靠性,大多数使用率报告都依赖于医疗保险数据。

 近几年,无创诊断成像(NDI)诊断成像是医疗保险参保者中增长最快的项目之一,使用率趋势逐年增高。由于数据的可用性和可靠性,大多数使用率报告都依赖于医疗保险数据。尽管商业保险的人群比医疗保险的受众者更多,但只有少数研究者关注不同商业保险人群的NDI使用趋势。此外,这些研究中所用的分类成像方法也有很大不同。因此,在医疗保险和商业保险人群之间没有可靠的NDI使用率比较。

近日,发表在Radiology杂志的一项研究探讨了无创诊断成像(NDI)在商业保险人群中的使用率,并通过模式分析了NDI使用率的趋势,并将其与医疗保险服务付费参保者的使用率进行了比较。

本研究对2003年至2016年期间的NDI进行了回顾性趋势分析,据索赔数据库中所述,每年对所有注册了服务付费医疗保险的成年人和大约900万商业保险患者进行统计。商业保险患者分为两组:18-44岁和45-64岁。NDI同样的程序代码定义适用于医疗保险和商业索赔,计算每1000名参保者的费率,并根据模式(CT、MRI、核成像、超声心动图、超声、x线片)报告随时间推移的总体趋势。联合点回归用于建模年增长率和确定有统计学意义(P< .05)的变化趋势。

在几乎所有情况下,医疗保险参保者对每种医疗方式的使用率均最高,其次是45-64岁的商业保险患者,然后是18-44岁的患者在2000年代中期至后期,这三个群体的医疗保健使用率都出现了增长(每年每1000名参保者的医疗保健成像:91[95%置信区间{CI}: 34,148];年龄45-64岁的商业保险患者:158[95%CI:130,186];18-44岁:83岁[95% CI: 69,97]),随后从2000年代末到2010年代初出现了显著的下降趋势(每年每1000名参保者的医疗保健成像:-301 [95% CI: -510,-92];商业保险患者年龄45-64岁:-54[95%CI:-69,-39];年龄18-44岁:-26岁[95% CI: -31,-21]),与联邦医疗保险(CT、核成像、超声心动图)制定的编码捆绑事件相符。在没有编码捆绑的模式中有显著的趋势变化(MRI, x线片,超声),尽管大多数表现为平坦的趋势。在2010年代初以后出现了明显的趋势变化,主要表现为使用率增长持平。值得注意的是,2012年后,在45-64岁的商业保险患者和医疗保险参保者中,CT成像的增长趋势发生了显著变化(每年每1000名参保者的医疗保健成像:17 [95% CI: 6,28];商业保险患者年龄45-64岁:11[95%CI:2,20])。

 

图1 该图显示了基于保险年龄组的所有无创诊断成像(NDI)诊断成像的使用率,基于联合点回归程序(版本4.5.0.1)的分析。实线是建模的趋势; 虚线是观察到的速率。

 

表1 基于2003-2016年联合点分析的各保险年龄组的成像率、趋势和趋势变化。

综上所述,医疗保险服务收费人群和商业保险人群的成像使用趋势大体相似,尽管前者的使用率一直较高。在经历了2000年代中期的快速增长,2000年代后期和2010年代的全面放缓后,我们注意到,在45-64岁的商业保险患者和医疗保险人群中,CT的使用率明显增加,这足以阻止这些人群中之前整体成像使用增长率的下降。
