Maximizing acceptability and usefulness of an automated telephone intervention

Abstract

The objective was to describe the utility of mixed methods to inform the development of an automated telephone intervention to improve patients’ compliance with asthma medication. As part of intervention development for a larger trial, we conducted 15 focus groups ( n = 53) to design and develop calls, and to identify factors influencing intervention acceptability and usefulness. We piloted four call types and interviewed 64 participants to further improve call content and receptivity to the intervention. Feedback led to several changes to the intervention scripts and eventual calls, and an initial pilot led us to drop one of the calls. During the pilot, we reached 43 percent of target participants; 74 percent of those stayed on the call until it ended. This process provided key insights about automated calls, and may have broader applicability for the development of automated interventions designed to help patients manage a variety of chronic conditions.
