We will recruit 300 adults, each to be followed for at least 1 year with moderate or severe persistent asthma from clinics serving low-income, urban, primarily minority patients and conduct a randomized controlled trial (RCT) to: 1) assess whether 6 months of the PAI improves asthma control relative to baseline compared with usual care (UC) and whether such a difference is sustained in the 6 months following the intervention's completion, 2) Assess whether the PAI improves other asthma outcomes (need for prednisone bursts, ED visits, hospitalizations, quality of life, FEV1) relative to baseline compared with UC at 6 months and is sustained in the 6 months following the intervention's completion, 3) examine mediators and moderators of the relationship between the intervention and outcome, 4) assess the incremental direct and indirect costs of the PAI compared to usual care and the cost-effectiveness of the PAI relative to UC for the outcomes, and 5) in post-study focus groups of providers to explore awareness of the intervention and response to the PA
