Creating reusable scenarios using clinFHIR

One of the main reasons for developing tooling to support the clinical Connectathon (now re-branded as clinicians on FHIR) was for Clinicians to use it to ensure that FHIR would meet clinical needs, using specific scenarios as ways of testing it. (Actually our initial scenarios were far too big – but that’s all part of the learning process!)

At the events, we have groups of clinicians that take a scenario and then build sets of resources that could represent that scenario using a test patient – often there is more than one way we can do this, and one of the purposes of the event is to develop ‘best practice’ guides. One of the things that would be nice to do is to be able to save – and then reload – these scenarios so that they can be shared with others and examined outside of the event. (It would also help negate the issue that all this work is saved in test servers that are periodically cleared).

More about contained resources

So this is going to be a really short post.

There was a question on the Implementers chat about the ability for contained resources to reference each other (ie where there are multiple contained resources within the same parent.

Here’s the question (slightly paraphrased):

The FHIR spec states that Contained resources can’t contain other resource (understandable). But I thought I had seen references from those contained resources to other contained resources within the same parent. Is that valid?

eg: a Medication resource is contained within a MedicationStatemement resource. The Medication references other Medication and Substance resources, also contained within the MedicationStatemement.

Talking with a Clinician

So I was talking with one of my colleagues at Orion Health today – a clinician who has just joined us and wanted to understand what FHIR was – to a reasonable degree of detail. I thought I’d summarize our conversation here as it’s useful to record what a clinician found interesting, and wanted to know about.

Server roles in FHIR

As part of the preparation for the connectathon and clinicians challenge at the WGM in October, I decided to update clinFHIR so that it can access different servers for data and ‘conformance’ resources like ValueSet and StructureDefinition. Currently clinFHIR assumes that everything it needs to operate is supplied by a single server – from looking up profiles (StructureDefinition resources), finding and expanding ValueSets through to actually storing and retrieving the resources created for a patient. This is fine when the server is Grahames, as he aims to implement the entire specification (and generally succeeds!) but it’s a big ask for any server to do this.
