Study design details

• Main study objective:
  To describe real-world Australian primary care practice in COPD care over the period 2015-2019 in the light of the CONQUEST Quality Standards (QS), in patient populations with high-risk COPD which is either diagnosed or undiagnosed.
• Outcomes:
  Assessment of: active identification of undiagnosed patients with potential high-risk COPD, disease & quantification of future risk in newly diagnosed patients, appropriate pharmacological and non-pharmacological therapy provision in newly-diagnosed patients and already-diagnosed patients, whether high-risk COPD patients are followed up appropriately over a 12m period after index date.
• Data analysis plan:
  Descriptive analyses will be performed on the characteristics of high-risk patients and of primary care medical management of COPD in each patient group (undiagnosed, newly-diagnosed, already diagnosed). All summary statistics will be presented as percentages with counts (categorical variables) and mean/medians with standard deviation/interquartile ranges for normally and non-normally distributed continuous variables respectively. The yearly trends in Australian practice in COPD care will be described (2015-2019) in tables, and graphs to show the trends for key outcomes longitudinally over the 5-year assessment period.
