To determine the key features, utilities, and functionalities of an adherence dashboard so that patients, care partners, and healthcare providers can effectively use it to identify and improve medication nonadherence. A qualitative study was conducted in four stages. In Stage 1, semi-structured interviews and focus groups were conducted with patients, care partners, and healthcare providers after showing existing dashboards to gain feedback and determine their needs and preferences for the dashboard. In Stage 2, data gathered from Stage 1 were used to develop paper prototypes. In Stage 3, these prototypes were evaluated by participants to refine the design. Finally, in Stage 4, a framework for the key components of the adherence dashboard was developed based on user feedback. Some of the key features identified include individualized medication adherence, overall adherence summaries, customizable notifications, real-time data visualization, and integration with existing healthcare systems such as electronic health records (EHR). Participants also highlighted the importance of intuitive design, ease of navigation, secure data handling, and the ability to customize the dashboard according to user preferences. This study identifies key features and functionalities and provides a user-centered framework for designing a real-time medication adherence dashboard tailored to the needs of patients, caregivers, and healthcare providers. Future work will focus on developing a fully functional dashboard, integrating it into clinical practice, and evaluating its effectiveness in improving medication adherence.
