Official title: UMEC/VI compared to TIO for Time-to-First Inpatient Admission and Readmission in an Initial Maintenance Therapy Population
Trial description: Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory disease characterized by impaired airflow due to chronic inflammation of air passages in the lung. Due to the progressive nature of COPD-related symptoms, subjects often experience significant reductions in their health-related quality of life that correlate with disease severity. Tiotropium (TIO) is a long-acting muscarinic antagonists (LAMA), used commonly in the management of COPD. Further, those with severe breathlessness are recommended by Global Initiative for Chronic Obstructive Lung Disease (GOLD) to initiate therapy on a dual bronchodilator (i.e., LAMA + long-acting beta2 agonists [LABA]). Umeclidinium/vilanterol (UMEC/VI) is a once-daily single dose LAMA/LABA combination inhaler. Studies have shown that UMEC/VI was associated with lower lifetime medical costs and better cost-effectiveness than TIO. While UMEC/VI has demonstrated ability to reduce airway obstruction, its effect on COPD-related healthcare resource utilization (HRU) is sparse in the literature. The objective of this study will be to evaluate the time-to-first on-treatment, rate of on-treatment COPD-related inpatient admission and all-cause and COPD-related 30-day and 90-day readmission among subjects with COPD initiating treatment with UMEC/VI compared to TIO. A retrospective matched cohort design will be utilized with medical and pharmacy claims data including enrollment information from the Optum Clinformatics™ Data Mart Database for admission analysis during the identification period (01-Jan-2014 to 31-Dec-2018). Inpatient readmissions will be described among the subset of subjects who experience at least 1 on-treatment COPD-related inpatient admission, are alive at discharge, and are continuously enrolled for 30 days (for the 30-day readmission analysis) or 90 days (for the 90-day readmission analysis) following the discharge date of their first inpatient admission.

- >=1 pharmacy claim for fixed-dose UMEC/VI or TIO during the identification period (between January 01, 2014 and December 31, 2018 [or September 30, 2018; depending on the most recent data available]). The date of the first prescription filled will be termed as the index date.
- >=1 medical claim with an international classification of diseases (ICD) diagnosis code for COPD in any position (primary or secondary) during the pre-index period or on the index date.
- >=1 pharmacy claim for inhaled corticosteroid (ICS-), LABA-, LAMA- containing controller during the pre-index period, excluding the index date.
- Pharmacy claims for non-index controller medications on the index date.
Inclusion and exclusion criteria
Inclusion criteria:
- >=1 pharmacy claim for fixed-dose UMEC/VI or TIO during the identification period (between January 01, 2014 and December 31, 2018 [or September 30, 2018; depending on the most recent data available]). The date of the first prescription filled will be termed as the index date.
- >=1 medical claim with an international classification of diseases (ICD) diagnosis code for COPD in any position (primary or secondary) during the pre-index period or on the index date.
- Continuous enrollment with medical and pharmacy coverage of >=12 months prior to the index date. The 12 months prior to the index date (and including the index date) will be termed the pre-index period.
- >=40 years of age in the year of the index date.
- (Readmission analyses only) >=1 on-treatment inpatient admission (i.e., hospitalization) in the post-index period and alive at discharge.
- (Readmission analyses only) Continuous enrollment with medical and pharmacy coverage of >=30 days after the index discharge date for the analysis of 30 Day readmissions, or >=90 days after the index discharge date for the analysis of 90 Day readmissions.
Exclusion criteria:
- >=1 pharmacy claim for inhaled corticosteroid (ICS-), LABA-, LAMA- containing controller during the pre-index period, excluding the index date.
- Pharmacy claims for non-index controller medications on the index date.
- Pharmacy claims for both UMEC/VI and TIO on the index date.
- Pharmacy claims for multiple inhaler triple therapy (MITT) on the index date.
- >=1 medical claim with a diagnosis for asthma in the pre-index period.
