CENTRALIZED

Efficient healthcare delivery relies heavily on accurate, accessible, and secure patient information. In Nigeria, the current method of managing patient records remains largely manual, fragmented, and uncoordinated across different healthcare facilities. This has led to frequent duplication of medical tests, prolonged waiting times, and poor continuity of care. The need for a centralized and interoperable digital solution is therefore essential in improving patient outcomes and overall healthcare efficiency. This roject focuses on the design and prototype implementation of a web-based Electronic Health Record (EHR) system named HealthHive. The system aims to consolidate patient medical data from multiple hospitals into a single, secure, and user-friendly platform accessible to patients, healthcare providers, and administrators. HealthHive emphasize interoperability, scalability, and data security while ensuring that patient privacy is upheld through role-based access control and encrypted communication. The project adopts the Object-Oriented Analysis and Design (OOAD) approach, with modeling tools such as Use Case Diagrams and Class Diagrams utilized to represent the system’s architecture and interactions. The proposed system demonstrates how centralized digital records can minimize redundancies, promote data sharing between healthcare institutions, and enhance decision-making through accurate medical histories. Ultimately, this prototype lays the foundation for a national EHR framework capable of transforming healthcare management in Nigeria by improving accessibility, efficiency, and trust within the healthcare ecosystem.
