The advancement and integration of Electronic Health Record (EHR) systems into mobile solutions have transformed healthcare by offering a wide array of new services. This chapter explores the pivotal role of mobile-based solutions in national healthcare, emphasizing their accessibility, portability, and ability to integrate smart devices and sensors to enhance patient care. We investigate various country-specific implementations of mobile EHR solutions, analyzing technical architectures, interoperability standards, and the challenges these systems face. Additionally, our study examines how these solutions effectively address the limitations of traditional healthcare settings by providing seamless, secure access to health data, improving healthcare delivery efficiency, and ensuring patient-centered care through innovative technologies, including AI-driven solutions and coaching systems. By evaluating these aspects, we aim to shed light on the effectiveness, user-friendliness, and potential impact of mobile EHR systems on healthcare experiences. These efforts are supported now by the recently voted European Health Data Space regulation. Ultimately, we advocate for a paradigm shift toward more integrated, patient-oriented healthcare solutions that benefit citizens.
