What are EHR interoperability standards?
The most widely recognized current standard of healthcare interoperability is FHIR (Fast Healthcare Interoperability Resources). FHIR is a standards framework leveraging the latest Web standards, focusing on implementation. H Level Seven International developed FHIR.
No matter the standard, (HIMSS) says interoperability and exchange standards must allow data sharing across clinical environments, labs, hospitals, pharmacies, and patients no matter the technology or the vendor. EHR interoperability is an effort dedicated to creating a data-sharing community.
Despite any current data sharing limitation, interoperability standards must continue to be developed by organizations like HL7 International, HIMSS and other organizations.
Several current standards speak to healthcare messaging, terminology, documents, frameworks, application, and even architectures. For example, some guidelines driving interoperability include:
HL7 V2.X and HL7 V3 speak to the exchange of demographic, clinical, and administrative data.
DICOM, owned by the National Electrical Manufacturers Association, is the mechanism that enables medical imaging devices – like picture archiving and communication systems (PACS) — to exchange images with other systems.
ASC-X12 provides design for exchange procedures, patient eligibility, and benefit payments.
IEEE 1073 determines messages to exchange with biomedical instrumentation equipment.
ICD-10 (International Classification of Diseases) defines a catalog of diagnoses and procedures for statistical purposes, billing, costs, and paperwork.
HL7 CDA (Clinical Document Architecture), CCDA (Consolidated CDA) and CCR (Continuity of Care Record) provide standards for documents used to indicate the type of information included in a report. These bodies define a consolidated view of patient summary health information, including allergies, treatment, care plan, and list of current health issues.
Despite these standards, there is no single technical standard that’s going to solve the problem of health IT interoperability, FHIR included.
