Trial Outcomes & Findings for Outcomes From Initial Maintenance Therapy With Fluticasone Propionate 250/Salmeterol 50 (FSC) or Tiotropium in Chronic Obstructive Pulmonary Disease (NCT NCT01387178)

NCT ID: NCT01387178

Last Updated: 2017-05-17

Results Overview

The mean cost per participant for COPD-related healthcare interventions for one year following the index date (first pharmacy claim for fluticasone propionate/salmeterol 250 µg/50 µg \[FSC\] or tiotropium bromide \[TIO\]) was calculated. Total medical costs included inpatient, emergency department, and outpatient costs associated with the treatment of COPD. Total pharmacy costs included costs of all COPD-related medications, and total healthcare costs included all medical and pharmacy costs that were related to COPD treatment. These costs were unadjusted and reflect the actual costs.

PRIMARY outcome

Timeframe: 1 year

Population: The total population including participants with index dates between January 1,2004 and June 30, 2008.

Moderate COPD exacerbations were defined as the occurrence of a COPD-related emergency department (ED) visit or a COPD-related office visit that is closely followed by a prescription claim for oral steroids or antibiotics. Severe exacerbations were defined as the occurrence of a COPD-related hospital admission.
