This study characterized the US COPD burden, including socioeconomic and health-related quality of life (HRQoL) outcomes.Study Design and Methods: In this retrospective, cross-sectional study using nationally representative estimates from Medical Expenditures Survey (MEPS) data (2016– 2019), adults (≥ 18 years) living with and without COPD were identified. Adults living without COPD (control cohort) and with COPD were matched 5:1 on age, sex, geographic region, and entry year. Demographics, clinical characteristics, socioeconomic, and generic HRQoL measures were examined to include a race-stratified analysis of people living with COPD.Results: A total of 4,135 people living with COPD were identified; the matched dataset represented a weighted non-institutionalized population of 11.3 million with and 54.2 million people without COPD. Among people living with COPD, 66.3% had ≥ 1 COPD-related condition; 62.7% had ≥ 1 cardiovascular condition, compared to 33.5% and 50.5% without COPD. More people living with COPD were unemployed (56.2% vs 45.3%), unable to work due to illness/disability (30.1% vs 12.1%), had problems paying bills (16.1% vs 8.8%), reported poorer perceived health (fair/poor: 36.2% vs 14.4%), missed more working days due to illness/injury per year (median, 2.5 days vs 0.0 days), and had limitations in physical functioning (40.1% vs 19.4%) (all P< 0.0001). In race-stratified analyses for people living with COPD, people self-reporting as Black had higher prevalence of cardiovascular-risk conditions, poorer socioeconomic and HRQoL outcomes, and higher healthcare expenses than White or Other races.Conclusion: Adults living with COPD had higher clinical disease burden, lower socioeconomic status, and reduced HRQoL than those without, with greater disparities among Black people living with COPD compared to White and other races. Understanding the characteristics of patients helps address care disparities and access challenges.Keywords: COPD, burden of illness, healthcare cost, race/ethnicity
