发表在《J Manag Care Spec Pharm》的一项由美国科学家进行的研究考察了美国健康医疗组织中哮喘患者吸入式含糖皮质激素治疗升级情况和结局。

背景:哮喘是一种影响约8%美国人的常见疾病。

人群:治疗指南提示将吸入式糖皮质激素(ICS)作为主要治疗,但ICS治疗的患者哮控制不佳较为常见。治疗升级(增加ICS剂量并加入其他控制疗法)用于控制症状。升级后的真实世界研究的结局或为治疗决策提供信息。

目的:(1)描述升级治疗的哮喘患者的特征和治疗模式,(2)评估升级后的结局(恶化、哮喘未得到控制和健康医疗资源使用[HCRU])。

方法:通过ICD-9-CM哮喘码(≥2个日期493.xx)和2009年1月1日至2014年9月30日长期(>1剂)含ICS治疗的起始(明确索引日期),从大型美国管理赔付数据库中确定研究队列。索引日期之前和之后需要1年的连续入组。升级定义为≥以下1项:ICS剂量增加;ICS、长效β-2激动剂(LABA)或白三烯调节剂(LTRM)转换为不同的ICS、LABA或LTRM;或添加控制药物(即,抗体生物制剂)。考察升级模式。计算恶化率(定义为7天内住院、急诊[ED]或门诊就诊,并处方1种口服皮质类固醇药物[OCS])和哮喘未控制率(定义为1年中>4剂短效β激动剂[SABA],≥1剂OCS,或≥1次哮喘相关ED或住院)。估算每例患者每年(PPPY)HCRU。

结果:在35126例初始始长期含ICS治疗的患者(平均[SD]年龄38[16]岁)中,5044(14%)例患者在建立标记(即,升级前时间)后136(105)天升级了他们的标记方案。最频繁的独立或联合变化包括ICS剂量增加(68%)或添加LABA(27%)或LTRM(25%)。升级前,恶化率为1.60(5.10)PPPY,1108例(22%)患者经历恶化。升级后的251.6(138.9)天,恶化率为0.75(2.9)PPPY,1038例(21%)患者经历恶化。升级后的251.6(138.9)天中,恶化率为0.75(2.9)PPPY,1038例(21%)患者经历恶化。升级前后,大部分恶化(>85%)与7天内门诊就诊+OCS药物处方相关。升级前,哮喘的未控制率为41.5%,升级后为41.0%。升级前(平均[SD] 24.0[26.7] 全因和8.5[13.4]哮喘相关PPPY)和升级后(19.3[21.3]全因和4.6[8.1] 哮喘相关PPPY)的非卧床治疗访问较常见。

结论:在初始长期含ICS方案的哮喘患者中,约14%的患者在初始后1年内升级疗法。但是,在治疗升级后1年内,21%的患者出现≥1次恶化,41%的患者出现哮喘未控制。这些结果证实,升级含ICS治疗的哮喘患者的需求未得到满足。
