FSH Seminar

Computable Name:

FHIR (pronounced “fire”) is a standard for health care data exchange. FHIR Implementation Guides (IGs) are “a set of rules of how a particular interoperability or standards problem is solved”.1

This course is a comprehensive overview of IG authoring for those interested in creating FHIR IGs using FHIR Shorthand, also known as “FSH” (pronounced “fish”).

Learning objectives

  1. Become familiar with the FHIR specification, and commonly used FHIR resources and element types.
  2. Learn the recommended process for successfully planning a new IG
  3. Gain proficiency with the FHIR Shorthand ecosystem of tools (FSH, GoFSH, SUSHI)
  4. Learn how to create the common components of an IG, including FHIR profiles, code systems, and value sets
  5. Learn about key FHIR profiling concepts including value set binding, cardinality, MustSupport, slicing, and extensions
  6. Awareness of common clinical code systems including LOINC, SNOMED, ICD10, and code systems in the HL7 terminology list

Prerequisites

The course content assumes basic familiarity with FHIR – if you haven’t worked with FHIR before in any capacity, see the FHIR Resources page for some general introductory information.

No experience with reading FHIR IGs, or with FHIR IG authoring/profiling is necessary. These topics are covered in Part 1 and 2, respectively. Readers who are already familiar with FHIR IG authoring should still review Part 2 as this describes the technical setup process for using the FSH tools.

We recommend completing the course materials over two days as described below.
