Exercises - or your own thing!
Details below for some exercises for creating/managing FHIR Terminology resources and for using them. But if you have something from your own work that you want to try to do that's even better - we're happy to help with that.
Use the FHIR chat as needed for support
How's it all going?

Create a CodeSystem for Australian jurisdictions. Include hierarchy to indicate which are states and which are territories.
Create another CodeSystem from a spreadsheet or other tabular source. If you don't have one of your own, try
Browse CodeSystem in Shrimp
Map the created CodeSystem to SNOMED CT or LOINC
|Can translate using the ConceptMap in Postman|
Create a ValueSet
Create a ValueSet for a subset of codes. If you need an example, create a set for diabetes conditions in SNOMED CT
Browse the ValueSet in Shrimp
ECL challenge 1
|Create an ECL expression to define a ValueSet for all the different types of stroke.|
ECL challenge 2 - bonus points
Create an ECL expression to define a ValueSet for all substances, which are an active ingredient in any product containing paracetamol (90332006).
Step 1 - typeahead search
Create a UI in your favourite technology that allows a user to select a concept from a CodeSystem restricted to a ValueSet. Display the selected concept details.
If you don't have one to work with from your own use cases try the Emergency Department Reference Set 32570361000036108 ).
If you want a starting point there's a Let's Build project at https://github.com/jimsteel/termdemo that has a good starting point and follow along instructions.
Step 2 - boosting
Update your search from step 1 to search from all clinical findings 404684003, but boost the members of the Emergency Department Reference Set 32570361000036108 .
Try searching for "hyper" or "anxiety" or "diabetes" with and without the boosting.
Documentation can be found at https://ontoserver.csiro.au/docs/6/ext-boosting-vs.html
Step 3 - dynamic widget types
Try different types of UI controls for ValueSets of different sizes - for example radio buttons for less than 5 options, autocomplete type-ahead search for long lists.
For small ValueSets try
User can search for and select a concept.
|Suggest a replacement|
Identify an inactive SNOMED CT concept and provide a list of possible replacements from SNOMED CT's historical association reference sets - these are exposed as "implicit ConceptMaps" with the following URIs
You could allow a user to paste in an inactive SNOMED CT concept ID or a list of IDs, or you could try to allow users to search the inactive concepts in SNOMED CT and select one.
|User can find replacements of different types for an inactive concept|
Is the following coding valid in the implicit ValueSet for the reference set 32570361000036108 from SNOMED CT-AU? How would you find out?
|Fix an invalid FHIR resource||Valid FHIR resource|
|ValueSet differences||Find the difference in the expansion of a ValueSet using two different versions of a terminology. For example the new and removed "Containered Trade Product Pack" (CTPP) concepts in AMT between two versions of SNOMED CT-AU - this is the implicit ValueSet URI for CTPP concepts http://snomed.info/sct?fhir_vs=refset/929360051000036108.|
How many of the following does the Australian Emergency Department Reference Set 1244621000168103 contain
How do those numbers compare to all of SNOMED CT?
