Digital health is an established research area in information systems (IS) research. The domain involves individual human behavior, the broader social, healthcare providers, and other organizations. The rapid spread and use of health technologies have opened up considerable opportunities for research to evaluate and test existing theories. To generate an overview of the status quo, we apply the belief-actionoutcome (BAO) framework as a lens to understand how current research has addressed the various aspects of digital health. Overall, we analyzed 46 studies from well-regarded IS outlets. Therefore, we aim at providing a comprehensive review and synthesis of the literature. Our results indicate a focus on behavioral research and action formation, but also a void regarding design-oriented studies, as well as multi-level studies. In summary, this study develops a research agenda for digital health, which includes six research questions that address research focus, health phenomena, at the macro-and micro-level.
