FHIR
The Fast Healthcare Interoperability Resource, or FHIR (pronounced "fire"), is a data standard that describes data formats and elements (known as "resources") and an API (Application Programming Interface) for exchanging electronic health records. The standard was created by the Health Level Seven International (HL7) health-care standards organisation. FHIR builds on previous data format standards from HL7, like HL7 version 2.x and HL7 version 3.x. The advantage of using the FHIR standard is that is is easier to implement because it uses a modern web-based suite of API technology. (from Wikipedia)
Interoperability: FHIR as a standard for health records
To effectively communicate data, there must be a standard way of modelling that data so all parties can understand the meaning of the data. At its core, FHIR is simply a description of how healthcare data can be organised and presented, so there are no ambiguities about its meaning, regardless of the parity accessing it.
Implementation and development of a tech ecosystems
FHIR is not only a data model for health data. FHIR has also in-build a protocol to facilitate the implementation of systems using the same technology that web browsers use. FHIR is also an API-driven data standard and uses the same transmission protocols that ordinary web browsers do. FHIR API resources use the same principle that other systems do by doing a sensible grouping of related concepts. For example, it makes sense to group in a resource the name, phone, date of birth, address, and sex of a customer. The FHIR specification defines many API resources that represent the common units of healthcare data interchange: patients, diagnosis, providers, locations, consent, etc.
