The FHIR® Standard is maturing, and increasingly being adopted for integration projects across the globe.
It is becoming essential that clinicians and informed patients become involved in these projects, as they depend on the correct representation of clinical information being shared between clinical systems - an area that is notoriously difficult to get right. In this paper we will discuss what a clinician needs to know about FHIR to be able to knowledgeably participate in these projects. We will start with discussing the fundamentals of FHIR, focusing on those aspects that the clinical user should be familiar with, and then discuss the tooling that is being developed to help people gain an understanding of FHIR. We will conclude with a discussion of the overall process that can be used to develop the FHIR artifacts.
