HL7 (Health Level Seven) is a set of international standards for the exchange, integration, sharing, and retrieval of electronic health information. FHIR (Fast Healthcare Interoperability Resources) is a standard for exchanging healthcare information electronically that was developed by HL7. HL7/FHIR integration and healthcare app development can help hospitals and specialist surgeries improve their patient care by providing fully compliant and interoperable software solutions that enable effective cooperation among providers, including hospitals, clinics, and laboratories, and informed decision-making.
