Real-world Drivers Behind Communication, Medication Adherence, and Shared Decision Making In Minority Adults with Asthma.

Background: Inhaled corticosteroids (ICS) are the foundation of asthma management. However, ICS non-adherence is common. Black adults have lower ICS adherence than white adults, which likely contributes, in part, to the asthma disparities that Black adults experience.
Objective: To explore how Black adults with uncontrolled asthma and their primary care providers communicated about ICS non-adherence and used shared decision-making to identify strategies to increase ICS use.
Design: Eighty routine clinical visits for uncontrolled asthma were audio recorded and inductively analyzed using methods adapted from grounded theory methodology.
Participants: Study participants included 80 Black adults (83% female) largely low-income (83% Medicaid) and their 10 primary care providers. The study settings were 2 Federally Qualified Health Centers.
Key Results: Three overarching themes were identified: (1) ICS misuse and lack of knowledge; (2) external influences informed personal misconceptions about ICS; and (3) patient-provider communication to individualize plan of care.
Conclusions: Reasons for ICS non-adherence in Black adults with uncontrolled asthma offer potential targets for interventions that facilitate enhanced adherence. Future research should include PCP training on strategies that support patient-centered care, such as communication, shared decision-making and patient engagement.
