Types of interoperability in healthcare
Interoperability in healthcare can be categorized into four types, each addressing different aspects of data exchange.
1. Foundational interoperability
Foundational interoperability is the most basic level, enabling data from one health information technology system to be received by another. This level ensures the secure transfer of data, such as emails or PDFs, without requiring the receiving system to interpret it. A hospital can share a PDF document with a patient’s discharge information, which the receiving system can store but not further process.
While foundational interoperability is crucial for Health Information Exchanges (HIEs), it lacks the functionality for meaningful data usage in healthcare. Agreement on standards and protocols is necessary for achieving foundational interoperability, enabling different systems to exchange data securely and effectively.
2. Structural interoperability
Structural interoperability focuses on how data is formatted and standardized for exchange between systems. This level ensures that the exchanged data is organized in a way that allows for meaningful communication and processing across various platforms.
This level of interoperability enables healthcare providers to identify care gaps and integrate recommendations into a patient’s ongoing medical record, enhancing the continuity and quality of care. Standardized data formats in structural interoperability facilitate seamless data input and output, promoting more effective care coordination.
3. Semantic interoperability
Semantic interoperability ensures that both sending and receiving systems share a common understanding of the data exchanged. This level is crucial for accurate machine-to-machine communication and patient care.
The Health Level 7 (HL7) V3 standard introduced the Reference Information Model (RIM), foundational for achieving semantic interoperability in healthcare. FHIR resources further simplify healthcare data exchange by breaking down complex information into manageable units, promoting semantic interoperability.
Challenges of interoperability in healthcare

Examples of interoperability in healthcare
Let’s explore some real-world examples to see how interoperability works in practice.
1. Appointment check
- Verify appointments: Interoperability standards allow patients to easily verify their appointments through mobile or web applications.
- Request for appointment: The request for an appointment check is relayed from the application to the hospital information system. Upon receiving the request, the hospital information system communicates with the electronic medical record using standardized messages.
- Compiles appointment details: The electronic medical record retrieves and compiles the appointment details and relays this information back to the hospital information system. The appointment details are then conveyed to the patient via the application, completing the request process.
2. Hospital transfer
- Authorization request: The transfer of a patient involves sending a request from one hospital to another medical institution. The hospital transfer process is initiated by the first doctor submitting a request through their electronic medical record system.
- Sending data: During a hospital transfer, all clinical data related to the patient is automatically transferred to the receiving hospital’s electronic medical record system.
- Review: After receiving the transfer approval, the first doctor reviews the request to ensure everything is in order.
- Approval: Upon receiving the transfer request, the second doctor approves it. The approval of the patient transfer is communicated back to the first hospital through a standardized message sent to their electronic medical record system.
3. Lab test results request
- EMR: The process of requesting lab test results involves a doctor using an EMR to generate a digital request to the laboratory. Upon receiving a request, the laboratory returns a standardized report to the EMR used by the doctor.
- Analysis: After getting the lab test results, the doctor analyzes them through the EMR and communicates the findings to the patient.
Advances in technology promise to further enhance healthcare interoperability. AI and machine learning are poised to revolutionize predictive analytics, allowing healthcare providers to foresee patient outcomes and tailor treatments more effectively.
These technologies can analyze vast amounts of data to identify patterns and AI automation trends that might not be immediately apparent to human clinicians.
