          Abstract

          Purpose

          To characterize and estimate the proportion of patients with chronic obstructive pulmonary disease (COPD) who continue to exacerbate while receiving triple therapy and further describe these patients according to blood eosinophil counts.

          Methods

          This was an analysis of the 2017 Adelphi Real-World Respiratory Disease Specific Programme (DSP) survey of patients with COPD from France, Germany, Italy, Spain, and the United Kingdom (UK). Demographics were assessed on the date of completion of the physician/patient questionnaire; clinical characteristics were captured for the previous 12 months. The proportion of patients receiving triple therapy, who had experienced ≥2 moderate or ≥1 severe acute exacerbations of COPD (AECOPD) in the 12 months prior to index, and had blood eosinophil counts ≥150 cells/µL (T-AECOPD-EOS150) or ≥300 cells/µL (T-AECOPD-EOS300), were calculated.

          Results

          In total, 2876 patients were included of which 762 had an eosinophil value. A higher proportion of patients in the ≥300 cells/μL eosinophil group (55.9%) compared with 150–<300 cells/μL (48.7%) and <150 cells/μL (47.1%) groups experienced ≥2 moderate and/or ≥1 severe AECOPD in the year prior to index. The ≥300 cells/μL eosinophil group had the lowest reported level of health-related quality of life (HRQoL). More severe disease in terms of comorbidities, lung function, healthcare resource use, and HRQoL was seen in patients with ≥2 moderate or ≥1 severe AECOPD in the year prior to index while receiving triple therapy, compared with patients who did not meet these criteria. In total, 10.6% and 6.2% of the COPD population, respectively, met the criteria for the T-AECOPD-EOS150 and T-AECOPD-EOS300 cohorts.

          Conclusion

          This analysis demonstrates that there is a subpopulation of patients with COPD who continue to experience exacerbations despite receiving triple therapy; approximately three-quarters of these had eosinophils ≥150 cells/μL and one-third had eosinophils ≥300 cells/μL; these patients may benefit from eosinophil-targeted therapies.

          Real-world physician and patient behaviour across countries: Disease-Specific Programmes - a means to understand.

          Treatment guidelines and strategies are often based on data from randomized controlled trials and observational clinical studies. These sources drive treatment decisions, yet the data they provide may have limited relevance to the wider population in real-world clinical practice due to the narrow selection criteria applied to patients in trials. Information used to inform clinical practice and improve patient outcomes can, therefore, be unreflective of real-world clinical situations. The purpose of this article is to assess the value of Adelphi Disease Specific Programmes (DSPs) as sources of real world data. DSPs are large, multinational, observational studies of clinical practice for a range of common chronic diseases. Treatment practice data are collected by physicians (n = 700) who are asked to provide information for the next 10 patients consulting for a specific condition. These patients (n = 7000) are also invited to fill out a self-completion form providing their own assessment of symptoms, expectations and quality of life. This article provides examples of the statistical techniques that have been employed to analyse the data in terms of cost/burden of illness, quality of life, disease severity and progression, compliance and adherence to therapy, impact of treatment guidelines and analyses of unmet need. DSPs can support clinical understanding of how diseases are managed including rationale for doctor decision-making and patient attitudes to their condition. Comparisons with other data sources and limitations of the programmes are discussed (including the fact that, unlike claims databases and registries, the DSPs are cross-sectional and not longitudinal).

            Whether high blood eosinophils are associated with chronic obstructive pulmonary disease (COPD) exacerbations among individuals with COPD in the general population is largely unknown.
