The objective of this study was to assess the treatment for patients with rheumatoid arthritis (RA) in the USA.
This study entailed analysis of claims data for patients with RA who initiated treatment with oral methotrexate (MTX) or a biologic in 2009 (n=48,910) or 2012 (n=107,636) and had follow-up for 4 years (2009 cohort) or 2 years (2012 cohort).
A biologic was initiated before MTX for 27% of the 2009 cohort and 36% of the 2012 cohort. Concomitant use of MTX and a biologic declined from 74.1% (2009 cohort) to 45.4% (2012 cohort).
MTX is underused in the treatment of RA in the USA.
本研究的目的是评估美国类风湿关节炎(RA)患者的治疗情况。
本研究对2009年(n = 48,910)或2012年(n = 107,636)开始使用口服甲氨蝶呤(MTX)或生物制剂治疗且有4年随访期(2009年队列)或2年随访期(2012年队列)的RA患者的理赔数据进行了分析。
在2009年队列中,27%的患者在使用MTX之前开始使用生物制剂,在2012年队列中这一比例为36%。MTX与生物制剂的联合使用从74.1%(2009年队列)降至45.4%(2012年队列)。
在美国,MTX在RA治疗中的使用不足。
