It’s currently fed by HL7 version 2 messages and there’s a User Interface for authorized users, but there was always a plan to introduce a FHIR interface to some point – something that has been accelerated by the current COVID pandemic of course. So what would a FHIR API look like?
We spent a bit of time in the last post describing why we want to have data coded, how FHIR supports coded data – especially the external terminologies where the concepts are defined – and described some of the RESTful API calls that we could make to retrieve specific Observations and DiagnosticReports from the repository.
This year marked my inaugural voyage to HL7® FHIR® DevDays , alongside my Redox colleagues, Autumn Ike , and Mike Paetz. This blog represents our collective Top 5 takeaways from this year’s 4-day affair. This expert community built around FHIR is as collectively passionate as they are incredibly knowledgeable.
Over the next several weeks I will release a series of blogs highlighting the way Redox is helping our customers overcome these gaps to uncover the possible. Up first: Using bulk FHIR. What is bulk FHIR? That’s where bulk FHIR comes in. bulk FHIR is a significant step closer to that.
Examples are probably one of the more useful things to an implementer – yet likely the least exciting part of building an Implementation Guide (IG) to the designer. But the tooling to create examples is not that great. Admittedly it does require a basic understanding of FHIR – but well within the reach of a Clinician or BA.
Bulk Data Access The addition of a Bulk Data Access in #FHIR was a hot topic at the San Diego workgroup meeting. Grahame has explained it on his blog. The only hint at what the Problem is a fragment of a sentence in the first paragraph of Grahame's blog article. ". Which is not a definition of a use-case.
As FHIR matures, the security topic becomes more and more important. In fact the specification they have " FHIR OAuth 2 " is not open for review, yet. It is made up of a set of strings that represent a few FHIR resources. It is not a complete list of FHIR resource types.
I have been working with some of the teams wanting to do something with Privacy Consent and are coming to the FHIR Connectathon in San Diego. For example: Role Based Access Control (RBAC), or Attribute Based Access Control (ABAC). An example of this is -- SMART-on-FHIR. Another example has been shown as "Cascading OAuth".
If we need to we can extract other data from the token – we might want to check the scope of access for example, to determine if this user is allowed to perform the functionality we are providing. There’s a lot more information on SMART – including a number of posts on this blog. So that’s how we can make our app more secure.
I have been asked quite often to explain how to secure FHIR. The basics of Security for FHIR are written up on the FHIR Specification. Don’t worry about security The first answer is the one I give to those in HL7 that are working on developing FHIR, or just getting their feet wet learning FHIR. Not too big.
App Orchard, for its part, lets developers use a FHIR-based API to access an Epic development sandbox. Source : Bots in healthcare: interview with Thomas Schulz, Organiser of Botscamp [link] ) 2018 Digital Health Prediction 4 : Mobile phone manufacturers will follow Apple's lead on connecting to hospital EHRs using FHIR.
Thus lacking this permission, the FHIR Server would silently blind the user to any data that is restricted by Consent. I don't have example handy, but this is related to the reasons why break-glass is not universally accepted as necessary or even useful. I might blog further on these potential solutions.
As you’ll likely be aware, FHIR uses Implementation Guides (IG) to describe how to use FHIR for specific scenarios or use cases. He’s published it on his blog , but kindly allowed me to reproduce it here. In this example we want to make an implementation guide for a national project.
This article summarizes a concept that came from my blog reader. This kind of double pointers is discouraged in REST and in FHIR. Examples There is a basic example of a Patient delegating their father as their RelatedPerson. The resource objects are clickable to their examples.
The track itself defines a number of actors: The creator of an IPS document – for example an EHR (Electronic Health Record). This should be of value to servers implementing an IPS endpoint as well as useful to FHIR beginners as it has a number of useful visualizations. IG’s are the ‘next big thing’ for FHIR.
In the last article I show how PDQm can be made Asynchronous by using the FHIR Subscription. In the example from 200 partners, only 10 of them know of the patient of interest. I guess I really need to blog that mXDE environment. This improvement can also be done using FHIR Subscription and orchestration of each notification.
The recommendation I give here is restricted to the gross level: for Document Sharing at the XDS/XCA/DocumentReference metadata level; for FHIR REST at the returned Bundle.meta.security level, but not on each Resource in the Bundle; and for CDA at the CDA header, but not on each element. Available from the FHIR specification for easy reading.
The same question came to me regarding FHIR and http REST. There are two trading partners that have an agreement (Trust Framework) that one will be asking questions using FHIR http REST interfaces of the other party. There are many solutions, in my example it was F5 based load balancing hardware based TLS support.
I am a fan of using IHE-Connectathon for more comprehensive and formal testing, vs using the FHIR-Connectathon more for specification validation and experimentation. See my past articles on " What is a Connectathon ", " Maturing FHIR Connectathon without confusing the marketplace ". So I am not exactly sure if it is a good example.
Example is Apple adopting FHIR. For example Sequoia DURSA or DirectTrust ; Reference Implementation -- software provided in open-source by a consensus body as an implementation of a standard. Ideal Patient Centered Privacy Here are my notes extracted from my blog on Privacy Principles. This does happen. What's a Standard?
If there was more evidence needed that the company is seeking to have a "king-maker" effect in the healthcare world rather than play a provider role, its partnership with Best Buy Health is a clear example. Source: [link].
In one view, in the decade since then not much has changed, but in another view, an enormous amount of infrastructure has changed, and I think we’re on the verge of an eruption due to the success of the new FHIR data interface. Cross-posted from my own blog a week ago. And the data from my hospital blew up in my face.
We can't change Healthcare by writing very complex standards like the current FHIR ConsentDirective , which is fundamentally a " Contract " resource. First I recommend that FHIR make ConsentDirective a resource rather than just profiles of Contract. For example we an then add exceptions, which can be computable rules.
Available from the FHIR specification for easy reading. See FHIR Demonstration of DS4P. One specific example is 42CFR Part 2 – SAMSA covered treatment- that must be explicitly marked with a 'do not disclose without explicit authorization by the patient'. "M", because the content is less sensitive than normal, but still medical.
For example a weight scale wanting to record a new body-weight observation, where the scale knows the PMIR Registry and knows that the weight scale GUID is recorded as a Patient.identifier. WHY did PIXm and PMIR feed choose totally different technical approaches at the FHIR interaction? so that it can record that value.
While the underlying FHIR (aka, fast healthcare interoperability resource) deployed by DeepMind for Streams uses an open API, the contract between the company and the Royal Free Trust funnels connections via DeepMind’s own servers, and prohibits connections to other FHIR servers.
For example, if you wanted to engage with a telehealth visit, you could do so with the same set of credentials you use to see your past clinic notes and lab results, or to pay your bill. For example, we leverage a lot of FHIR APIs to pull information from Cerner and communicate that with DFD.
On the other hand, enhancing an existing system can be cost-effective and less disruptive but may limit the scope of innovation. Weighing the benefits and risks of each option is crucial in making a decision that aligns with your hospital’s vision and resources.
Duke Health, for example, saw a reduction in appointment cancellations and no-shows by using Xealth’s automated engagement tools. Understanding Xealth’s Digital Health Platform Xealth offers a comprehensive suite of digital health tools integrated with Electronic Health Records (EHR) to provide seamless access to patient data.
This blog post by Dr Joe Kvedar reflecting on Apple’s Health Record announcement makes for interesting reading ( I’m very optimistic about what this means for Patients and Carers ). mHealth Insight. “To quote Yogi Berra, “It’s déjà vu all over again.” Or so it seems.
