Patients in the ACC and CHW arms will have similar asthma outcomes (asthma control, quality of life, use of urgent care, appointment keeping, medication adherence, use of asthma actions plans). Compared to usual care, patients in the ACC and CHW arms will perform better on these outcomes. Patients with more severe asthma and those at greater risk of missed clinic appointments because of physical or cognitive impairment and psychosocial issues (e.g., substance abuse, mental illness) will be more likely to benefit from the CHW/home-based intervention.
