Toward Efficient Health Data Access for Mobile Applications Leveraging Human Digital Twins

Mobile health applications for chronic disease management require frequent access to health data for continuous monitoring and clinical decision support, creating performance challenges when accessing centralized platforms like Google's Health Connect (HC). This paper presents an evaluation of content provider mechanisms for optimizing health data access in Human Digital Twin applications. We developed a three-layer Human Digital Twin architecture implementing local data storage through Android's content provider interface, integrated with TEMPO, a hemophilia management application for continuous physical activity monitoring. Our experimental evaluation compared the HDT content provider approach against direct Health Connect access over continuous monitoring periods, with automated data requests across varying request sizes from single records to large batch operations. Results demonstrate that local data access through content providers can provide performance benefits over direct API access, with implications for healthcare applications requiring frequent data access.
