The proportions of patients with an exacerbation increased in most countries in 2021. Across each country, seasonal exacerbation increases seen during autumn and winter in pre-pandemic years were absent during the first year of the pandemic. The percentage of patients filling COPD prescriptions across each country increased by 4.53– 22.13% in 2019 to 9.94– 34.17% in 2021.Conclusion: Early, steep declines in exacerbation rates occurred in 2020 versus 2019 across all five countries and were accompanied by a loss of the seasonal pattern of exacerbation.Keywords: COPD exacerbation, chronic obstructive pulmonary disease, COVID-19, electronic health records, real-world study
