Abstract

This study discusses the development of an outpatient medical record information system at RSUP Dr. Hasan Sadikin Bandung in 2025. This study employs a literature review method with a qualitative descriptive approach to analyze the development of information technology in medical record systems. The study examines journals, academic books, government policies, and international standards related to electronic medical records. A needs analysis is conducted using the gap analysis approach by comparing the 2015 system with 2025 standards. Workflow mapping utilizes Data Flow Diagrams (DFD), while data structure analysis is performed using Entity-Relationship Diagrams (ERD). The findings identify areas for improvement and strategies to enhance the efficiency and effectiveness of the medical record system. The research findings indicate that there are still several major challenges in managing the information system, namely data inaccuracy and the risk of patient information theft. To address these issues, this study proposes various strategies, such as periodic data analysis, the implementation of encryption technology and two-factor authentication, AI-based automated recording systems, and cloud-based backup implementation. The success of this system is evaluated through indicators such as data accuracy levels, system security, efficiency in medical record management, and user satisfaction levels. It is expected that with the development of a more advanced and secure system, medical record management can become more effective, efficient, and support better healthcare services in the future
