The aim of this project was to carry out research in healthcare by developing Health Level 7-based software framework in order to provide health services for diverse communities of the world. The envisaged development of HL7 middleware software is focused on healthcare information systems already in use. The objective was to facilitate e-health services interoperable among various domains in the field such as laboratory, patient administration, pharmacy, billing and accounting etc. This project is based on HL7 version 3.0 standards because of its distinct benefits over previous versions. HL7 Version 3 is consistent with futuristic specification inherent in UML (Unified Modeling Language) models and object-oriented concepts. It offers an opportunity to provide an open source, vendor-neutral framework comprising generic components, integration mechanisms, together with a process for staged customization to meet not international standards but also the requirements of healthcare delivery organizations. Because of the diversity and complexity of the requirement, the project is conducted in several phases. In view of its cutting-edge nature, this software solution has the potential of establishing our national repute in the highly profitable and potent healthcare industry. The key benefits of this project are: • Local and global healthcare organizations including hospitals, medical laboratories and healthcare vendors may use this system to achieve inter-domain and across-domain semantic interoperability with the advantage of exchanging healthcare information in a secure and reliable manner. • Being a cost-effective open source, it may fetch leading service-orientated HL7 and ontology-based HL7 global recognition.
