<![CDATA[The rapid advancement of health information technology has encouraged hospitals to provide fast, accurate, and integrated healthcare services that support physicians' clinical decision-making. At TK III Ciremai Hospital, access to patient information and electronic medical records is currently limited to desktop- and web-based Hospital Information Systems (HIS), restricting physicians' mobility and reducing the efficiency of healthcare service delivery. This study aims to design a mobile-based Physician Information System integrated with the Hospital Information System (HIS) to enable physicians to securely access clinical information through Android smartphones. A qualitative research approach was employed using observation, semi-structured interviews, and document analysis to identify system requirements. The system was designed using the Waterfall software development model, while Java, MySQL, RESTful APIs with JSON data exchange, and Unified Modeling Language (UML), including Use Case Diagrams and Entity Relationship Diagrams (ERD), were utilized to develop the system architecture and database design. The scope of this study is limited to the system design phase and does not include system implementation or performance evaluation. The study produced a prototype design of a mobile-based Physician Information System that provides access to patient demographic information, electronic medical records, laboratory and diagnostic examination results, and physicians' practice schedules while emphasizing data security and usability. The proposed design is expected to serve as a reference for developing integrated mobile physician information systems that improve healthcare service efficiency, enhance physicians' mobility, and support evidence-based clinical decision-making in hospitals.]]>
