I just finished a very long week in Cologne at the HL7 workgroup meeting and FHIR Connectathon. I had the idea that I could host a discussion of how to use FHIR in a GDPR compliant organization. So I created a FHIR Connectathon track. This track was hopeful that we could do testing with various parts of the FHIR specification.

I will be giving a face-to-face tutorial on the topic of "IHE on FHIR" at both HL7 Workgroup meeting in Cologne, May 12-18 FHIR Dev Days in Boston, June 19-21 So, if you are in Europe, sign up for the tutorial at HL7 workgroup meeting. If you are in the USA, sign up for the tutorial at FHIR Dev Days.

The FHIR R4 ballot is out (see announcement), and I’d like to draw attention to one part of FHIR that we’ve been working hard on during the preparation of R4: Patterns. In FHIR, we made a specific decision to be as specific as we can get away with. FHIR Patterns. Specific vs General.

As you probably know, there are a number of ‘conformance’ resources in FHIR that have a unique ‘canonical’ Url that identifies them globally. This SHALL be a URL, SHOULD be globally unique, and SHOULD be an address at which this structure definition is (or will be) published. So back to FHIR versions. For ValueSet.

Looking at the proposal for the next version of FHIR (R5) it is multiple, but we can’t use that yet. The ‘plan definition’ extension specifies the url and value explicitly, while the ‘disease covered’ uses a named extension. These were: planDefinitionUrl. diseaseCovered.

I was trying to remember how to represent family relationships in FHIR – to record that one person is related to another, maybe a mother / daughter relationship, assuming that each person is already represented by a Patient resource. The following are the overall steps I followed. Install sushi. See the online instructions.

So a little while back I wrote about an app I developed during the WGM Connectathon to send an HL7 v2 message to a converter app, and display the response (a FHIR Bundle ) in a number of visualizations after validating it using the community supplied validation tool (actually, exposed by the reference servers via the $validate operation).

IHE ITI has a set of profiles on FHIR existing in Trial Implementation today. These were written against FHIR DSTU2. This profile does rely on creative systems engineering to decompose the documents into the FHIR resources. This might leverage CDA-on-FHIR, or some other methodology. This methodology is not specified.

Grahame Grieve is a principal with Health Intersections of Melbourne, Australia and was the architect-developer of HL7’s Fast Healthcare Interoperability Resources (FHIR, pronounced “fire”) specification that allows EHRs to exchange information. Was it weird to see FHIR as the only universal topic of HIMSS19? That definitely happens.

Before we start thinking of the specifics of coding in lab tests, a quick review of coded data in FHIR in general is probably a good idea. It can represent an external terminology such as LOINC or SNOMED, or can contain the actual definition of the concepts directly. This is a common pattern in the FHIR core spec.

FHIR defines a Questionnaire resource that specifies a set of questions for a user, along with a QuestionnaireResponse resource to capture their response. This extension says that the form filler takes a parameter which is a FHIR Patient resource. A variable has a name, and a value which is a list of resources or FHIR types.

Much discussion around consent (Privacy) in HL7 FHIR. FHIR should focus on only what systems do today, not what we want them to do. FHIR should put into common extensions those things that we want them to do (e.g. If we can agree on this, then the role of FHIR in capturing consent would be immensely clearer.

Bulk Data Access The addition of a Bulk Data Access in #FHIR was a hot topic at the San Diego workgroup meeting. Which is not a definition of a use-case. I have addressed this topic in FHIR before, FHIR does not need a deidentify=true parameter. This effort would best be done as the FHIR resources approach maturity.

This means that when I attended the FHIR Connectathon 14, prior to the HL7 Workgroup Meeting in San Antonio TX , I was shocked to experience the new FHIR Connectathon. The others from the FHIR core-team have seen the changes over-time, so the transition is not as shocking as it was for me. FHIR has matured, it is growing up.

There is renewed discussion, much like back in January, around the need to go beyond testing just the FHIR Resource 'interoperability'. A 'system' in the broadest of definitions. This reference system needs to pick a minimum-useful set of FHIR resource centric workflows. This is more than just a selection of FHIR Resources.
