The exchange of health information in today's world encompasses much more than just moving records between two systems. Health information exchange now sits at the intersection of interoperability standards, governance frameworks, compliance requirements, and the actual usability of the information in daily clinical and operational workflows.
This blog will provide an overview of how health information exchange functions today, including the use of various standards and TEFCA, and describe how organizations use exchanged data to support care delivery, operational effectiveness, and analytical capabilities.
What Health Information Exchange Means Today
Health information exchange (HIE), at its most basic, is the secure electronic transfer of health information between healthcare organizations, systems, and settings. However, expectations surrounding HIE have shifted since that time. Instead of assessing whether a piece of health information was successfully sent, healthcare organizations are now focused on whether it is usable when it reaches them.
Today’s priorities for HIE include:
- Timeliness of data delivery
- Completeness of patient records
- Accurate identity matching
- Strong governance and access controls
- Auditability and traceability
- Usability within clinical workflows
The gap between “data has been sent” and “data is useful” continues to grow, making it more vital to choose the right data collection and migration services.
The Standards Behind Modern Exchange
Interoperability standards provide the basis for cross-system exchange. In addition, most healthcare environments use multiple standards.
Interoperable standards commonly in use include:
- HL7 v2: An Example of Standard Transactional Messages, Like Admission and Discharge and Lab Result Messages
- CDA (Clinical Document Architecture): Exchange of Structured Documents.
- FHIR (Fast Healthcare Interoperability Resources): For API-based, flexible access to data.
- USCDI (U.S. Core Data Interoperability): As An Example Of A Standardized Data Model For Data Classes.
Using these standard models reduces ambiguity and provides greater consistency. Usage of these models enhances the ability of systems to communicate with each other.
These standard models will enable the development of new and innovative ways to deliver IT solutions needed to support modern healthcare delivery.
Where TEFCA Fits Into The HIE Picture
The TEFCA, or Trusted Exchange Framework and Common Agreement, is an important step toward achieving interoperability among healthcare organizations across the country.
TEFCA was developed by the Office of the National Coordinator for Health IT (ONC) to provide a framework for the creation of a “network-of-networks” that enables data transfer between organizations without needing to enter into individual agreements. Essentially, TEFCA will provide a means of developing a more cohesive environment for exchanging health information between various types of organizations.
TEFCA also provides:
- The same rules for participation
- Similar legal and technical requirements
- Additional connectivity among all types of providers, payers, governmental agencies, and the general public
Ultimately, TEFCA enables healthcare organizations to participate in large-scale data sharing. Because it provides a common foundation for exchanging data between organizations, the fragmentation associated with previous data-sharing methods should disappear over time.
What TEFCA Does Not Solve On Its Own
TEFCA establishes a general framework for healthcare organizations to share data, but it doesn't ensure that the data is clean, complete, or useful. It establishes a standard way for systems to share data, making it easier for them to work together.
TEFCA doesn't resolve problems with the quality of the source data. Healthcare systems can still have problems such as poor data quality, duplicate or mismatched patient identities, and incomplete or broken records.
So, just sharing data isn't enough to ensure true interoperability. Healthcare organizations need to improve the quality of their internal data, strengthen data governance, and ensure that workflows are in sync to get the most out of their benefits.
Real-World Use Cases That Make Exchange Worth The Effort
The best thing about health information exchange is when it makes real healthcare delivery better. It makes it easy for providers to move patients, set up referrals, and get full medical records in an emergency or after hours. It also lets providers and payers share records, helps with public health reporting, lets patients see their own data, and lets healthcare organizations report and analyze quality.
When health information exchange is used for its intended purpose, it can help improve continuity of care, reduce duplicate testing, and provide greater visibility across the organization.
Why Healthcare Data Compliance Still Shapes Every Exchange Strategy
With the increase in interoperability comes a greater responsibility for compliance.
Exchange strategies should consider the following:
- Role-based Access Controls
- The ability to audit both Access to Data and Data Modifications
- Minimum necessary use of data
- Consent and Governance Policies
- Accountability between Vendors and Networks
Healthcare data compliance is not solely about compliance with regulatory requirements but rather building trust with stakeholders.
TEFCA supports this goal by establishing a common set of privacy and security expectations for all networks. Organizations must ensure that data remains secure, traceable, and appropriately overseen during the exchange process.
What Strong Health Information Exchange Looks Like In Practice
A more mature way of exchanging health information focuses on usability rather than just connectivity.
When you think of a strong exchange environment, you will consider the following characteristics:
- Interoperability based on standards
- Framework alignment (for example, TEFCA)
- Data access is secure as well as auditable
- Data has been validated and normalized
- Data has longitudinal patient records across systems
Ready for care coordination, reporting, and analytics. This is the distinction between moving data and making it accessible and actionable.
More and more modern healthcare organizations are focusing on the ability to access data.
Frequently Asked Questions
What is the exchange of health data in the healthcare industry?
The exchange of health data is the electronic transfer of health-related information among entities, such as health insurance providers or medical professionals.
What is the impact of TEFCA on healthcare organizations?
TEFCA creates a consistent, well-defined structure and method for sharing health information across the United States, helping reduce the need for individual agreements and improving the ease and efficiency.
Why is it important that compliance with healthcare data laws continues to play a role in healthcare data exchange?
Compliance with data privacy and security laws fosters trust among participants in health information exchange and helps meet regulatory requirements.
If healthcare data is exchanged, how does it impact analytics and operations?
Exchanged health data provides a more complete dataset from which to analyze patient populations, enabling improved healthcare reporting, care coordination, and strategic decision-making.
