Impact of an Adherence Intervention Program on Medication Adherence Barriers, Asthma Control, and Productivity/Daily Activities in Patients With Asthma
2010
Objective. This study evaluated the impact of an asthma patient intervention program, with a focus on medication adherence on adherence barriers, asthma control, and productivity/daily activities. Methods. Patients ≥18 years old who were employed by a large Southeastern public school system, had ≥1 medical claim for asthma, and were taking ≥1 asthma medication were invited to participate in the study. The ASK-20, the Asthma Control Test (ACT), and a productivity questionnaire were administered before and after a 6-month period of intervention that involved the use of baseline ASK-20 results to create patient-specific reports on adherence barriers and talking points for care managers to use during the two outbound telephone calls addressing barriers identified. Patients also received three educational mailings. The ASK-20 is a brief, self-reported instrument developed to identify patient-specific barriers to medication adherence and to improve provider/patient communication about adherence. Results.
