Measure Description |
Time Frame |
|---|---|---|
|
Time to first COPD exacerbation
Time Frame: 12 months
|
The time to first COPD exacerbation will be calculated as the date of first COPD exacerbation minus index date.
A COPD exacerbation event is defined as any of three conditions: COPD related inpatient hospitalization, COPD related emergency department visit, or COPD outpatient/office visit with a pharmacy claim for OCS and/or antibiotics on the same day or within ten days.

|
All-cause utilization
Time Frame: 12 months
|
Frequency of all-cause resource use of: inpatient hospitalizations and length of stay, ICU admissions and length of stay, and outpatient/office visits.
Total number of different prescription medication classes filled will also be determined.
|
12 months
|
|
Treatment modification
Time Frame: 12 months
|
COPD medication use, such as treatment changes, will be captured post-index.
|
12 months
|
|
COPD exacerbation rates
Time Frame: 12 months
|
The rate of COPD exacerbation will be defined as the total number of COPD exacerbations during the post-index period for all patients in each treatment cohort divided by the total number of person years.
|
12 months
|
|
COPD respiratory medication use
Time Frame: 12 months
|
12 months
|
|
|
COPD related utilization
Time Frame: 12 months
|
COPD related outpatient/office visit, COPD related inpatient hospitalization length of stay , COPD related ICU admission and length of stay, COPD procedures.
|
12 months
|
|
All-cause and COPD related healthcare costs
Time Frame: 12 months
|
Costs will be reported for the following resource uses: inpatient hospitalizations, ED visits, outpatient/office visits, skilled nursing facility, total medical, and prescriptions.
Costs will be reported for all-cause as well as COPD related.
|
12 months
|
|
Treatment patterns and adherence
Time Frame: 12 months
|
Continuity of care during the 12 month post-index period will be measured with the Bice and Boxerman index.
Proportion of Days Covered (PDC) and Medication Possession Ration (MPR) will be used to measure the compliance of index medication (Symbicort or Spiriva) during the 12 month post-index period.
