ABSTRACT

The COVID-19 pandemic highlighted the crucial role of smartphone applications in managing public health crises, explicitly developed for lockdowns and social distancing. These apps faced challenges of broad acceptance, public trust, and rapid integration of sensitive medical data. The COMPASS initiative, part of the German government's Network University Medicine (NUM) projects, aimed to establish a modular platform for coordinated development and use of pandemic apps focusing on ease of use, free availability, sustainability, data security, and rapid deployment. The initiative sought to create a collaborative framework leveraging science, technology, and legislative experience to deploy efficient, effective, and research-ready health apps for pandemic scenarios. In this viewpoint, we examine how COMPASS utilized an interdisciplinary approach, combining expertise from nine university hospitals and external partners to develop app components, guidelines, and templates for pandemic management. The project focused on governance, best practices, regulatory and ethical compliance, research compatibility, interoperability, and a technology platform. Data from study apps like the Mainz Gutenberg Study Covid-19 App and SentiSurv App were analyzed to assess user engagement and app effectiveness. COMPASS successfully implemented study-related applications, developed technical components, and applied non-technical findings, generating nearly 1 million data points with over 25,000 participants. Achievements included a questionnaire editor, key component improvements, and contributions to projects like the digital InnovationHub CAEHR. The initiative emphasized data protection, user trust, and open-source solutions for future health crises. COMPASS represents a paradigm shift in utilizing mobile health applications for pandemic management, integrating technology, ethics, and user engagement, setting a precedent for future innovations in healthcare communication and epidemic response.
