| アブストラクト | PURPOSE: Selection of treatments for patients with chronic obstructive pulmonary disease (COPD) may impact clinical outcomes, healthcare resource use (HCRU) and direct healthcare costs. We aimed to characterize these outcomes along with treatment patterns, for patients with COPD following initiation of single-inhaler long-acting muscarinic antagonist/long-acting beta(2)-agonist (LAMA/LABA) dual therapy in the primary care setting in England. PATIENTS AND METHODS: This retrospective cohort study used linked primary care electronic medical record data (Clinical Practice Research Datalink-Aurum) and secondary care administrative data (Hospital Episode Statistics) in England to assess outcomes for patients with COPD who had a prescription for one of four single-inhaler LAMA/LABA dual therapies between 1st June 2015-31st December 2018 (indexing period). Outcomes were assessed during a 12-month follow-up period from the index date (date of earliest prescription of a single-inhaler LAMA/LABA within the indexing period). Incident users were those without previous LAMA/LABA dual therapy prescriptions prior to index; this manuscript focuses on a subset of incident users: non-triple therapy users (patients without concomitant inhaled corticosteroid use at index). RESULTS: Of 10,991 incident users included, 9888 (90.0%) were non-triple therapy users, indexed on umeclidinium/vilanterol (n=4805), aclidinium/formoterol (n=2109), indacaterol/glycopyrronium (n=1785) and tiotropium/olodaterol (n=1189). At 3 months post-index, 63.3% of non-triple therapy users remained on a single-inhaler LAMA/LABA, and 22.1% had discontinued inhaled therapy. Most patients (86.9%) required general practitioner consultations in the first 3 months post-index. Inpatient stays were the biggest contributor to healthcare costs. Acute exacerbations of COPD (AECOPDs), adherence, time-to-triple therapy, time-to-first on-treatment moderate-to-severe AECOPD, time-to-index treatment discontinuation, HCRU and healthcare costs were similar across indexed therapies. CONCLUSION: Patients initiating treatment with single-inhaler LAMA/LABA in primary care in England were unlikely to switch treatments in the first three months following initiation, but some may discontinue respiratory medication. Outcomes were similar across indexed treatments. |
