Short courses of systemic corticosteroids (SCS) are recommended to reduce recovery time from exacerbations, although SCS use has been associated with increased risk of adverse events.Methods: This study used 2013– 2019 Medicare 100% FFS research identifiable files, which contain all Medicare Parts A, B, and D paid claims incurred by 100% of Medicare FFS beneficiaries. Descriptive statistics for patients newly diagnosed with COPD were analyzed, including OCS use, select health conditions and acute events, and COPD exacerbations. Statistical models were used to analyze the relationship between the incidence of select health conditions and events and cumulative OCS dosage.Results: Of Medicare FFS patients newly diagnosed with COPD, 36% received OCS in the 48 months following diagnosis, and 38% of OCS episodes lasted longer than the recommended 5– 7 days. Patients had a variety of health conditions or acute events in the 24-month period prior to new COPD diagnosis, such as hypertension, depression/anxiety, type 2 diabetes, or osteoporosis, that could heighten the risks of OCS use. Patients treated with > 1000 mg of prednisolone equivalent OCS in the 48 months following COPD diagnosis had a higher incidence of new conditions or events, including cardiovascular disease, heart failure, hypertension, obesity, dyspepsia, infections, and depression/anxiety, than patients with no OCS use.Conclusion: These results highlight the potential risks of OCS in COPD treatment, including prolonged use among complex Medicare patients, and reinforce the importance of preventive treatment strategies and therapy optimization early in the disease course.Keywords: chronic obstructive pulmonary disease, systemic corticosteroids, SCS, OCS, COPD exacerbations, claims analysis
