What Is SMART on FHIR All About?
SMART on FHIR is a collection of interoperable protocols and guidelines that provide IT specialists in the healthcare sector a better way to develop and smoothly incorporate health-related applications. The protocol combines two robust health IT standards. So, what does SMART on FHIR stand for? Substitutable Medical Apps, Reusable Technologies (SMART), and Fast Healthcare Interoperability Resources (FHIR).
What Are SMART and FHIR?
Both counterparts work in tandem or separately. Yet, each one of them has a particular objective to complete.
SMART is a protocol, or a set of rules, that specifies how applications can be created to run across various healthcare systems. It fosters an ecosystem of safe, effective, and interoperable healthcare apps.
FHIR is a standard for healthcare data exchange published by HL7. It outlines how to represent various healthcare data types and how they can be exchanged between systems.
How Does SMART on FHIR Work?
SMART on FHIR operates through a sequence of well-defined steps:
- Authorization. The SMART app requests authorization from the FHIR server, outlining the required data.
- Granting Access. If the user permits, the FHIR server sends an authorization code to the SMART app.
- Exchange of Codes. The SMART app then exchanges this authorization code for an access token.
- Data Access. The SMART app can access the FHIR resources using this access token.
In simple terms, FHIR standardizes data while SMART standardizes how this data can be accessed.
