Brand to Generic Switching Patterns Among Advair Diskus Users with Asthma or Chronic Obstructive Pulmonary Disease (COPD): A Descriptive Analysis

In this request we assessed switching patterns among Inhaled Corticosteroids (ICS)/ Long-acting Beta-agonists (LABA) users with prior asthma or chronic obstructive pulmonary disease (COPD) and without recent history of pneumonia in the Sentinel Distributed Database (SDD). We performed a post-hoc analysis to plot the cumulative incidence of switching function for each pattern, which could account for treatment cessation as a competing risk for switching.

The study period includes data from February 1, 2019 up to December 31, 2020. We distributed this request to seven Sentinel Data Partners on September 7, 2021.
