Health Level Seven (HL7) is a set of international standards for the exchange, integration, sharing, and retrieval of electronic health information. It aims to improve the interoperability of health information systems, allowing different healthcare providers and organizations to communicate effectively. HL7 standards cover various aspects of healthcare data, including clinical documents, messages, and application programming interfaces (APIs). By facilitating seamless data exchange, HL7 helps enhance patient care, streamline workflows, and support healthcare research and analytics.
