Asthma-chronic obstructive pulmonary disease overlap and cost-related medication non-adherence among older adults in the United States.

Older adults with ACO represent a vulnerable population with increased risk for CRN.

Medication comprehensive review interventions have the potential of reducing the risk of CRN among the older Medicare beneficiaries with ACO.
