Developing Resilient Offline-First Architectures for Mobile Health and Clinical Research Applications

Abstract

This paper presents an offline-first mobile architecture that is intended to be used in mobile health and clinical research applications, especially in places where the network is either intermittent or scarce. Since continuous data collection of patients is frequently used in clinical studies and other research projects of public health, the proposed system will produce smooth and safe clinical data collection, symptom monitoring, document uploading, and eligibility processes even during the demanding network conditions. The architecture allows using encrypted local storage, data versioning based on a time stamp, and conflict-aware synchronous mechanisms to ensure the integrity of the data and its adherence to regulatory requirements, such as HIPAA. The secure retry features are provided by the system which helps in the transfer of data reliably when the system is connected again. The mobile health research platforms case study illustrates sustained amelioration in participant adherence, loss of data, and strong longitudinal data collection especially in the under-serviced groups like the rural or medically isolated groups. This study will help to enhance digital health equity by addressing the issue of low-bandwidth clinical settings and offering a solution that is fault-tolerant. The offline-first architecture helps the mobile health applications to be resilient in order to support patient-reported outcomes (PROs) and clinical research processes and offer the compliant, efficient, and secure data management. The approach provides an entry to more believable, holistic and scalable mobile health and clinical research infrastructure
