Effectiveness of Triple Therapy in COPD
Study Details
Study Description
Brief Summary
To assess the effectiveness of maintenance treatment of Chronic obstructive pulmonary disease (COPD) with the Long-acting beta2-agonist - long-acting muscarinic antagonists-inhaled corticosteroids (LABA-LAMA-ICS) combination with a LABA-LAMA combination on the risk of COPD exacerbation and the safety on the incidence of community acquired pneumonia.

Outcome Measures
Primary Outcome Measures
- Number of Participants Hospitalised With Severe Exacerbation [1 year]
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.
- Number of Participants Hospitalised With Moderate Exacerbation [1 year]
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.
- Number of Participants Hospitalised With Community-acquired Pneumonia (Serious Pneumonia) [1 year]
The primary outcome event for safety was the occurrence of the first hospitalization for community-acquired pneumonia (serious pneumonia).
Secondary Outcome Measures
- The Rate of COPD Exacerbations Over the One-year Follow-up [1 year]
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.

Study Results
Participant Flow
Recruitment Details | Base cohort consisted participants with ChronicObstructivePulmonaryDisease(COPD) who subsequently received at least one prescription for a long-acting bronchodilator, either Long-Acting Beta2-Agonist(LABA) or long-acting MuscarinicAntagonists(LAMA), or for inhaled corticosteroid(ICS), alone or in combination, from 1January2002 until 31December2015. |
---|---|
Pre-assignment Detail | Population-based incident new-user cohort design with high-dimensional time-conditional propensity score matching. The study cohort was formed from the base cohort using an incident new-user cohort design with time-conditional propensity scores. |

Arm/Group Description | The participants with COPD initiating treatment with LABA-LAMA-ICS combination as three or two inhalers on the same day were included in this group. Participants were followed for up to one year from the cohort entry date, the date of death, 31 March 2016, or the end of coverage in the practice, whichever occurred first. | The participants with COPD with their first concurrent prescriptions of a LAMA and LABA (no ICS) as two inhalers on the same day included in this group were matched on high-dimensional propensity score with patients initiating treatment with LABA-LAMA-ICS combination as three or two inhalers on the same day. Participants were followed for up to one year from the cohort entry date, the date of death, 31 March 2016, or the end of coverage in the practice, whichever occurred first. |
