Introduction and objectives Chronic obstructive pulmonary disease (COPD) is a costly condition. There is a need to identify patient characteristics associated with greater health care resource utilization and treatable traits. We compared COPD-related health care costs by treatment subgroups for UK patients with elevated blood eosinophil counts (BEC, defined as ≥0.45 ×109/L) who were at high risk of exacerbations (Global Initiative for Chronic Obstructive Lung Disease [GOLD] group C/D) with costs for low-risk patients (GOLD group A/B) with elevated BEC.
Methods Data from the Clinical Practice Research Datalink with Hospital Episode Statistics linkage were used to evaluate the GOLD grade and therapy for patients in a year prior to stable disease and elevated BEC (defined in this study as ≥0.45 ×109/L). Mean total COPD-related costs for 2016 were compared during a follow-up year for four groups of patients with elevated BEC: GOLD group C/D receiving triple therapy (TT; inhaled corticosteroid [ICS]+long acting β2-agonist [LABA]+long acting muscarinic antagonist [LAMA]), dual therapy (DT; ICS +LABA, ICS +LAMA, or LABA +LAMA), or other therapy (single or no maintenance inhaler), and GOLD group A/B.
Results Of 5046 patients with COPD and elevated BEC, 19% were GOLD group C/D receiving TT, 10% were GOLD group C/D receiving DT, 6% were GOLD group C/D receiving other therapy, and 64% were GOLD group A/B. Mean total COPD-related costs were three times as high for GOLD group C/D patients receiving TT as for GOLD group A/B patients, whereas costs for patients in GOLD group C/D in other therapy subgroups were not significantly greater than for those in GOLD group A/B (table 1).
Conclusions Patients graded GOLD C/D with elevated BEC receiving TT accounted for three times greater COPD-related costs than patients with less severe disease. This points to an unmet need and potential opportunity for intervention to alleviate burden of disease for these patients.
