    With the number and sophistication of HL7® FHIR® Implementation Guides rapidly increasing, knowing that your FHIR implementations are conformant to those IGs and the underlying FHIR specifications is more important than ever. Touchstone is the anchor of our FHIR validation ecosystem which empowers your FHIR implementation team to objectively measure the accuracy of their implementation […]

    Since our May 2023 Touchstone Release 6.0.0, the AEGIS Health IT team has been preparing the Touchstone community for our updated 2024 subscription pricing model. Touchstone 6.0.0 marks the transition from the introductory pricing accompanying our original R&D effort to a pricing model reflecting a production-hardened, full-featured enterprise-class product offering. This is our first Touchstone price […]

    During the past few HL7® quarterly FHIR® Connectathons and Workgroup Meetings, the FHIR community has been debating the impact of what I’m calling “version collisions:” when someone makes a FHIR request for healthcare data expecting that they will receive a response conforming to US Core 3.1.1, but they receive a response with data conforming to […]

    At this month’s virtual HL7® FHIR® Connectathon, you can validate the full end-to-end HL7 UDAP workflow, including automated checking of requests and responses and the contents of the JWTs within. HL7 UDAP (https://build.fhir.org/ig/HL7/fhir-udap-security-ig/index.html) is an OAuth-2-based authorization mechanism that is on the draft roadmaps of the national HIEs and TEFCA. Here’s a quick demo: https://youtu.be/pCCnV66sItA […]

    This is the second installment of our “FHIR Starter” series, which we are writing to help teams filter out the noise and excitement of the burgeoning FHIR community so they can focus on the signal–how to be successful with real-world FHIR implementations. If you missed our first installment, check that out here. In this installment, […]

    As the HL7® Fast Healthcare Interoperability Resources (FHIR®) community grows, an increasing volume of FHIR information and a ballooning community of self-appointed FHIR experts are bursting onto the scene. This is a welcome sign of the emergence of a robust FHIR ecosystem, and we celebrate that. Health IT is hard; as a technical domain, its […]

    “Escaped Defects” are defects that are discovered in production. Wow. Let that sink in for a moment. This is healthcare we’re talking about; people’s lives are on the line. Although the certainty of catastrophe is not the same as with a faulty space shuttle O-ring, the potential for patient tragedy is the payload of each […]

    Are we really publishing guides for implementation? If we want to buy a newly built house, we have a few options. The most common is choosing a standard floor plan from a community of houses being built by a mass-production builder. “Mass-production” means “build a few configurations (plans) many times to make each build most […]

    Are you under the impression that receiving an HTTP 200 (“OK”) response means your FHIR implementation is conformant to the FHIR specifications or implementation guide(s)? If so, we are sorry to disappoint you. In our work to help implementers accelerate their FHIR implementations, we see many tests that are looking for that “HTTP 200” response […]
