Interoperability and technologies

  • To identify needs in order to define how to adapt and implement reference standards
  • To promote the use of international reference standards (HL7 FHIR, SNOMED CT, LOINC, IHE, DICOM, OpenEHR, among others)  
  • To make clear accurate and useful technical reference information available to the entire community    
  • To provide recommendations and support to public and private organizations in the adoption of standards  

The interoperability is the ability to share information between systems or devices without losing its meaning. It enables access to information regardless of where it has been recorded and ensures its reuse minimizing blind spots and ensuring the care continuum.


SNOMED CT National Reference Center

The Interoperabilty and technologies area participates transversally in different projects of the Sistema de Salut de Catalunya. Some of the tasks performed are leading interoperability issues, assuming the tasks of developing HL7 FHIR messages or SNOMED CT and LOINC coding, developing pilots of the Social Terminology Server or being responsible for certification of HL7 FHIR test banks for devices for the monitoring of diabetes mellitus.

Some of them are described below.


The WiFIS (Work Flow for Health Institutions) interoperability framework allows the centers of the Integral Health System for public use in Catalonia (SISCAT) to exchange information in a standardized way. Standardizing the processes and communications between the systems of the Primary Care, Specialized Care and Mental Health centers.

In order to carry out the standardization of processes and communications, the Implementation Guidelines have been created, which define the standards, information exchange models, messaging and terminology to carry out this standardization. All the centers that follow the implementation guidelines will be able to connect to the interoperability platform defined for the iS3 project to exchange information with other centers that use the same protocol.

The main standards on which WiFIS is based on are the HL7 V2.5 messaging (with adoptions of version 2.7 and later) and the SNOMED CT terminology to represent the Spanish content.


A blood glucometer certification process was conducted during 2017 and 2018.

The objective of this area is to promote a common data exchange format so that the information generated by glucometers is interoperable.

The process consists of verifying that the device follows the PCHAlliance Continua guidelines. More specifically the ISO/IEEE 11073-10417 standard: Specialization of blood glucose measuring devices.


The Interoperability and technologies area has participated in the European ICTUSnet project, jointly led by the Master Plan for Cerebral Vascular Diseases of Catalonia and the AQuAS.

The tasks carried out by the TIC Salut Social Foundation focused on defining the interoperability framework.


As part of the SIMDCAT project, the Interoperabilty and technologies area has produced an evaluation report on DICOM Supplement 145, to standardize the representation, delivery and processing of digital pathology.

It has participated and participates in projects such as:

Label2Enable project

Nextcare project

RACSEL project

Antilope project

Trillium-Bridge II project

x-eHealth project

Secant project

04. Stakeholders and networking

The TIC Salut Social foundation it is a member of the following international standardization and interoperability organizations

SNOMED International, NRC (SNOMED CT National Reference CENTER)

SNOMED International it is a non-profit organization that holds the rights and ownership of the SNOMED CT (Systematized Nomenclature of Medicine – Clinical Terms) clinical terminology as well as the responsibility to update and distribute it internationally.

SNOMED Spanish Edition is the international version of the standard translated into LATAM Spanish.

Some countries maintain and distribute, as members of this organization, a national edition of SNOMED CT for use within their territory. The Spanish Extension is the national edition for the Spanish territory maintained by the SNOMED CT National Reference Center for Spain, Ministry of Health, Consumer Affairs and Social Welfare.


HL7 International – HL7 Spain

It is the official entity of HL7 International that works in the development of global data interoperability standards in the field of health and promotes the use of HL7 standards in Spain through the participation of events throughout the country, courses, training or publication of guides and manuals on the use and implementation of the standards.

It is the only accredited organization in Spain for the training and certification of HL7 standards among health professionals.

Integrating the Healthcare Enterprise (IHE)

It is a non profit Healthcare Standards Development Organization, founded in 1987, that works internationally and is currently one of the most important in medical informatics messaging standards.

The IHE promotes the coordinated use of established standards such as DICOM and HL7 to address clinical needs. Its mission is to provide a comprehensive framework of standards related to the exchange, integration, and retrieval of electronic health information that supports clinical practice and management to enable interoperable digital workflows.

LOINC International

LOINC International is a non-profit medical research organization associated with the Indiana University. This organization promotes the international LOINC (Logical Observation Identifiers Names and Codas) standard, which SISCAT is used to represent laboratory tests.
