Exercises: Content

Exercise	Description	Success
Create CodeSystem	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 Wikipedia's List of microorganisms used in food and beverage preparation. Consider using hierarchy and properties. For convenience Wikipedia's list has been turned into CSV and XLSX - organisms.csv, organisms.xlsx	Browse CodeSystem in Shrimp
Map CodeSystem	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).

Exercise	Description	Success
Simple search	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 (ValueSet URI: http://snomed.info/sct?fhir_vs=refset/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 http://snomed.info/sct?fhir_vs=isa/404684003, but boost the members of the Emergency Department Reference Set 32570361000036108 http://snomed.info/sct?fhir_vs=refset/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 http://hl7.org/fhir/ValueSet/administrative-gender http://hl7.org/fhir/ValueSet/encounter-reason http://hl7.org/fhir/ValueSet/v3-FamilyMember	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 http://snomed.info/sct?fhir_cm=900000000000526001 http://snomed.info/sct?fhir_cm=900000000000527005 http://snomed.info/sct?fhir_cm=900000000000523009 http://snomed.info/sct?fhir_cm=900000000000489007 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
Validate codes	Is the following coding valid in the implicit ValueSet for the reference set 32570361000036108 from SNOMED CT-AU? How would you find out? { "name": "coding", "valueCoding": { "code": "241649002", "system": "http://snomed.info/sct", "display": "MRI" } }
Fix an invalid FHIR resource	Provided the example FHIR resource, use the server's validation API to find and fix the validation errors. InvalidCondition.xml InvalidAllergyIntolerance.xml	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.
Query exercise	How many of the following does the Australian Emergency Department Reference Set 1244621000168103 contain diabetes conditions diabetes conditions other than gestational diabetes lung diseases left lung diseases left lung diseases that aren't infections How do those numbers compare to all of SNOMED CT?
