Chronic Obstructive Pulmonary Disease (COPD)-Related Outcomes and Costs for Patients on Combination Fluticasone Propionate-Salmeterol Xinafoate 250/50mcg Versus Anticholinergics in a Comorbid COPD-Depression/Anxiety Population

NCT01337336 COMPLETED Results posted

The objective of this study was to examine COPD-related outcomes for patients with comorbid depression/anxiety who are on combination fluticasone propionate/salmeterol xinafoate compared to those receiving anticholinergics. The prevalence of comorbid depression/anxiety in patients with chronic obstructive pulmonary disease (COPD) is estimated to be high and range from 10-40%, given that the risk of depression/anxiety symptoms is almost 3 times higher in patients with versus without COPD. Additionally, patients with comorbid COPD and depression/anxiety have higher COPD-related healthcare utilization and costs compared to those without depression/anxiety. Therapy with maintenance medications for COPD has been recommended to prevent future adverse COPD outcomes, but the impact of initiating these interventions has not yet been evaluated in a higher-risk population with comorbid COPD-depression/anxiety. The present study compares the risk of COPD exacerbations and COPD-related costs in patients initiating maintenance medications for treatment of COPD in a comorbid COPD/depression-anxiety population. Maintenance medications include inhaled corticosteroid (ICS), long-acting beta agonist (LABA), combination drug product of ICS+LABA, and anti-cholinergics (AC) including tiotropium (TIO) and ipratropium or combination ipratropium-albuterol (collectively abbreviated as IPR).

Conditions

• Pulmonary Disease, Chronic Obstructive

Interventions

• fluticasone propionate/salmeterol xinafoate
• Anticholinergics

Primary outcomes

• Number of Participants With Any Chronic Obstructive Pulmonary Disease (COPD)-Related Exacerbation — Maximum of 1 year after index date (January 1, 2004 to June 30, 2009)
  The number of participants with any of the following COPD-related exacerbations during the follow-up period was computed: COPD-related hospitalization, emergency room (ER) visit, or physician visit with a prescription (Rx) for oral corticosteroid (OCS) or antibiotic within 5 days of the visit. The index date is defined as the date of first chronologically occurring COPD maintenance medication of interest during an identification period spanning January 1, 2004 to June 30, 2008.
