Underuse of controller therapy among Medicaid-enrolled children is common and leads to more emergency department (ED) visits and hospitalizations. However, there is little evidence about the relationship between medication adherence, outcomes and costs once controller therapy is initiated. ⋯ Although greater adherence was associated with lower rates of ED visits, higher medication expenditures outweighed the savings. The overall low adherence rates suggest that quality improvement initiatives should continue to target adherence regardless of the class of medication used. However, low baseline hospitalization rates may leave little opportunity to significantly decrease costs through better disease management, without also decreasing medication costs.
