Insights into API Use to Enable Data Sharing between EHRs and Apps
Standards and Protocols That Support API Interoperability
Bringing health data together in a unified way relies heavily on standardized protocols. These protocols ensure that data is interpreted consistently, forming the backbone of API-driven health data exchange. They act as a shared language, enabling healthcare providers, tech developers, and consumer health platforms to exchange information smoothly across the U.S. healthcare system.
The creation of these protocols is the result of years of teamwork between healthcare professionals, tech experts, and regulators. Their adoption has revolutionized how health information flows. Now, a patient’s data can seamlessly travel from a primary care doctor to a specialist, from a hospital to a pharmacy, or even from wearable devices to clinical care systems.
HL7 FHIR and SMART on FHIR Standards
Health Level Seven Fast Healthcare Interoperability Resources (HL7 FHIR) has become the go-to standard for modern healthcare APIs. By replacing outdated messaging systems with REST APIs and JSON, FHIR simplifies integration processes.
FHIR organizes health data into modular "resources" such as patients, medications, and care plans. This means systems can request only the specific data they need instead of transferring entire patient records. For instance, a pharmacy system might pull just medication details without accessing unrelated medical history.
Building on FHIR, the SMART on FHIR framework adds essential layers of security and authorization. This enables controlled third-party access, making it ideal for patient-facing apps and clinical decision-making tools that integrate with existing healthcare systems.
Major electronic health record (EHR) vendors like Epic and Cerner (now Oracle Health) have adopted these standards, driven in part by regulatory requirements. The 21st Century Cures Act played a key role in this shift by mandating that healthcare providers make patient data accessible through standardized APIs, with penalties for blocking information.
Clinical Terminology Standards
Even when systems can exchange data, they must also agree on what that data means. Clinical terminology standards ensure that terms like diagnosis codes, lab results, or medication names are interpreted the same way across different platforms.
- ICD-10 (International Classification of Diseases, 10th Revision) provides universal codes for diagnoses and procedures. For example, a diabetes diagnosis coded in ICD-10 will be understood consistently, whether it’s stored in an EHR, sent to an insurer, or used in public health research.
- LOINC (Logical Observation Identifiers Names and Codes) standardizes lab tests and clinical observations. A blood glucose reading coded with LOINC retains its meaning, whether it comes from a hospital lab or a home glucose monitor.
- RxNorm creates a standardized naming system for medications, linking brand names, generics, and dosages. This reduces the risk of medication errors caused by inconsistent naming.
- CPT (Current Procedural Terminology) codes standardize medical procedures and services, ensuring smooth billing and care coordination.
Together, these standards enable semantic interoperability - allowing systems not just to share data but to interpret it accurately. Without this shared understanding, connected systems would function like people speaking different languages, even if they’re using the same communication tools.
Open Standards and Vendor-Neutral Design
The strength of healthcare interoperability lies in its open, vendor-neutral approach. Unlike proprietary systems that lock users into specific ecosystems, open standards promote competition and allow organizations to adopt solutions that best meet their needs.
With open standards, healthcare providers can switch vendors or add new systems without overhauling their entire infrastructure. This flexibility drives innovation while ensuring compatibility across platforms.
The HL7 organization leads the development of these standards through collaboration with healthcare providers, tech companies, regulators, and other stakeholders. This inclusive process ensures the standards address practical needs and are adaptable across different healthcare settings.
Open source tools further boost adoption. For example, the HAPI FHIR library provides free resources for developers to create compliant applications, lowering barriers for smaller organizations and startups to join the interoperable ecosystem.
The Office of the National Coordinator for Health Information Technology (ONC) has also been instrumental in advancing open standards. Through certification programs and initiatives like the Trusted Exchange Framework and Common Agreement (TEFCA), the ONC aims to build a nationwide health information exchange network based on these standardized protocols.
