| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Participants With All-cause Hospitalizations, Emergency Department (ED) Visits, Observation Stays, and Deaths | 12 months following randomization | Covariates included in the adjusted multivariate models were age, FEV1% predicted, Charlson comorbidity index, oxygen use, hospitalization for COPD in previous 12 months, outpatient treated COPD exacerbation in previous 12 months, length of time since acute care utilization to randomization, use of LABA or ICS, PA level and study site |
| Secondary | Number of Deaths Among Participants | 12 months following randomization | Covariates included in the adjusted multivariate models were age, FEV1% predicted, Charlson comorbidity index, oxygen use, hospitalization for COPD in previous 12 months, outpatient treated COPD exacerbation in previous 12 months, length of time since acute care utilization to randomization, use of LABA or ICS, PA level and study site |
| Secondary | Number of Participants With All-cause Hospitalizations | 12 months following randomization | Covariates included in the adjusted multivariate models were age, FEV1% predicted, Charlson comorbidity index, oxygen use, hospitalization for COPD in previous 12 months, outpatient treated COPD exacerbation in previous 12 months, length of time since acute care utilization to randomization, use of LABA or ICS, PA level and study site |
| Secondary | Number of Participants With All-cause Emergency Department Visits | 12 months following randomization | Covariates included in the adjusted multivariate models were age, FEV1% predicted, Charlson comorbidity index, oxygen use, hospitalization for COPD in previous 12 months, outpatient treated COPD exacerbation in previous 12 months, length of time since acute care utilization to randomization, use of LABA or ICS, PA level and study site |
| Secondary | Number of Participants With All-cause Observation Stays | 12 months following randomization | Covariates included in the adjusted multivariate models were age, FEV1% predicted, Charlson comorbidity index, oxygen use, hospitalization for COPD in previous 12 months, outpatient treated COPD exacerbation in previous 12 months, length of time since acute care utilization to randomization, use of LABA or ICS, PA level and study site |
| Secondary | Number of Participants With COPD-Related Hospitalizations, ED Visits, and Observation Stays | 12 months following randomization | Covariates included in the adjusted multivariate models were age, FEV1% predicted, Charlson comorbidity index, oxygen use, hospitalization for COPD in previous 12 months, outpatient treated COPD exacerbation in previous 12 months, length of time since acute care utilization to randomization, use of LABA or ICS, PA level and study site |
| Secondary | Number of Participants With COPD Exacerbation | 12 months following randomization | COPD exacerbations were ascertained via pharmacy records and utilization data. An outpatient COPD exacerbation will be defined as a care touch (clinic visit, phone, or secure message encounter) with a diagnosis of COPD accompanied by a prescription of either an oral steroid or an antibiotic within 2 days |
| Secondary | COPD Assessment Test, CAT - 12 Months | 12 months | The reported mean change between the baseline and 12 Months scores for the Chronic Obstructive Pulmonary Disease Assessment Test (CAT). Score range is 0-40. A negative change score indicates fewer symptoms. |
| Secondary | Physical Activity | 12 months | Patients were categorized as being: completely inactive (0 mins/week), insufficiently active (1-149 mins/week) or active, meeting national physical activity recommendations (\>150 mins/week) of moderate to vigorous physical activity. |
| Secondary | Personal Health Questionnaire, PHQ8 - 12 Months | 12 months | The reported mean change between the baseline and 12 Months scores. Score range is 0-24. A negative change score indicates less depressive symptoms. |
