What researchers measure

Primary outcomes

  1. Number of Participants Hospitalised With Severe Exacerbation

    The primary outcome event for effectiveness was the first COPD exacerbation to occur after cohort entry. The event was defined as a hospitalization with a primary diagnosis of COPD (severe exacerbation) is presented.

    Time frame: 1 year

  2. Number of Participants Hospitalised With Moderate Exacerbation

    The primary outcome event for effectiveness was the first COPD exacerbation to occur after cohort entry. The event was defined as a hospitalization with the prescription of an oral corticosteroid, namely prednisolone (moderate exacerbation) is presented.

    Time frame: 1 year

  3. Number of Participants Hospitalised With Community-acquired Pneumonia (Serious Pneumonia)

    The primary outcome event for safety was the occurrence of the first hospitalization for community-acquired pneumonia (serious pneumonia).

    Time frame: 1 year

Secondary outcomes

  1. The Rate of COPD Exacerbations Over the One-year Follow-up

    This outcome was based on the number of hospitalizations and on the number of courses of treatment with an oral corticosteroid. A gap of at least 30 days between treatment courses was required to consider the exacerbations as separate events.

    Time frame: 1 year

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2018 to primary completion in Nov 2018, 0 months.

Results were first posted in Dec 2019, 1 year after primary completion.

Of 99 industry-sponsored observational studies under Pulmonary Disease, Chronic Obstructive, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 41. This study's 0 months is below that.

Counting every sponsor, half of 429 studies reached it within 28 months; a quarter within 16 and three quarters within 62.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 3, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
