Making education count: the nurse's role in asthma education using a medical home model of care.

Asthma care for patients who have limited health literacy is very costly. The resources to help patients who have lower health literacy levels are very few are not well identified. Significant gains in asthma control, self-efficacy in managing asthma, and improvement in overall costs of care for this patient population can be achieved when health literacy challenges are addressed. This research suggests that one-on-one education with an asthma educator that specifically addresses health literacy levels and care designed around the National Asthma Guidelines can produce significant reductions in the cost for asthma care through decreased emergency department visits and hospitalizations, and improved self-management of asthma exacerbations.
