A patient advocate to facilitate access and improve communication, care, and outcomes in adults with moderate or severe asthma: Rationale, design, and methods of a randomized controlled trial

We test whether the PA intervention, compared to usual care, is associated with improved and sustained asthma control and other asthma outcomes (prednisone bursts, ED visits, hospitalizations, quality of life, FEV1) relative to baseline. Mediators and moderators of the PA-asthma outcome relationship are examined along with the intervention's cost-effectiveness.
