- At least one diagnostic code of COPD at age 35 years or above in the primary care setting.
- At least one prescription of a single-device LAMA/LABA or ICS/ LABA inhaler within the indexing period with a prior COPD diagnosis. The first/ earliest within-class prescription will determine the index date for analysis.
- At least one diagnostic code of any medical conditions incompatible with a COPD diagnosis at any time in the participant’s medical history, example; conditions that are related to lung or bronchial developmental anomalies, degenerative processes (cystic fibrosis, pulmonary fibrosis) pulmonary resection or other significant respiratory disorders other than COPD that can interfere with clinical COPD diagnosis or substantially change the natural history of the disease.
- At least one diagnostic code of COPD at age 35 years or above in the primary care setting.
- At least one prescription of a single-device LAMA/LABA or ICS/ LABA inhaler within the indexing period with a prior COPD diagnosis. The first/ earliest within-class prescription will determine the index date for analysis.
- A forced expiratory volume in one second (FEV1) / forced vital capacity (FVC) <0.7 at any time in the participant history prior to and including index date.
- Record linked to hospital episode statistics.
- Continuously registered with a general practitioner practice for a minimum of 12 months (365.25 days) prior to the index date.
- At least one diagnostic code of any medical conditions incompatible with a COPD diagnosis at any time in the participant’s medical history, example; conditions that are related to lung or bronchial developmental anomalies, degenerative processes (cystic fibrosis, pulmonary fibrosis) pulmonary resection or other significant respiratory disorders other than COPD that can interfere with clinical COPD diagnosis or substantially change the natural history of the disease.
