Creating a FHIR document
October 26, 2017
A FHIR Document is simply a collection of resources inside a Bundle, with a Composition resource to hold the ‘Document level’ information. clinFHIR has special functionality to support building a document, which is triggered by adding a Composition to the scenario. Here’s a scenario before adding the Composition (a couple of Lists and an encounter):
(Note that we’ve used the ‘hide selector’) to hide the left pane. And here’s the display after the Composition is added:
(Note the new ‘Document’ tab that has appeared next to the ‘Graph’ tab).
Select that tab, and click the ‘Add section’ link. A dialog appears that allows you to select the code for the section (from the valid LOINC codes) and also any text for that section. Here’s a screen shot:
Save the section and you are then able to add resources to that section. In the next screen shot, we’ve clicked the (+) symbol to the right of the Medication list to add it to the section. We don’t need the actual medications to the section (and we shouldn’t), as they are referred to by the medication List.
If we then display the Graph view, we can see that a reference from the Composition to the List has been made automatically. In the next screen shot we’ve added a link to the Problem List, plus a reference from Composition to Encounter. We’ve also hidden the Patient resource (There’s a link just above the graph) – as that can clutter the display.
To view the document structure, select the Tree View subtab (off the ‘Document’ tab, and click the ‘generate tree’ link. Here’s the result:
To view the actual bundle, display the ‘Description’ tab, then the ‘Bundle Json’ – like this.
You can continue to build up your document as you need to. At the time of writing this post, there isn’t a good way to generate the text – that’s coming!
