Background: As new combinations of inhaled corticosteroids (ICSs) and long-acting β(2)-agonists (LABAs) become available for the treatment of asthma, it will be important to determine criteria against which they can be evaluated. The aim of this study was to assess which attributes of combination therapy physicians consider most important.
Methods: Primary and secondary care asthma specialists (n = 32) were recruited for an expert Delphi process that was performed over three rounds to determine attributes perceived to be important in the selection of combination therapy.
