#CQL is an open language for clinical logic. Quality measures. Decision support. Computable guidelines. Cohorts. Readable for authors, executable for systems. Older than the #FHIR boom. Not married to FHIR either. But most energy is on CQL with FHIR now, via big quality measurement efforts.
CQL on FHIR is in balloting now, CQL version 2 has been released last month as a standard for trial use.

A very preliminary list from the #HL7WGM in Pittsburgh right now on which #FHIR resources have been proposed to move out of the core specification with the R6 version and where they may go.

Was also inspired by seeing the AI based guide validation that Kereval demoed. See example output here: fhir-testing.gazelle-platform.net/examples It verifies softer requirements from the Best Practices IG and generates test cases based on the IG content. #HealthIT #Interoperability

Time for some updates from the #HL7WGM in Madrid this week! 🇪🇸 Let's start with the Connectathon over this weekend. My main focus was the #EHDS track with @hl7europe.bsky.social and comparing multiple profiles side-by-side for compatibility. I hacked together a little application to make a start.

FHIR tattoo and Christmas designs on the official HL7 shop aren't bad either. European shipping best via hl7-international.myspreadshop.co.uk, US via hl7-international.myspreadshop.com. The 🦴 and 🗡️ look a bit ominous for the standard's fate though 😅

An SQL-on-FHIR overview in 4 slides! There's people who think #FHIR is only for data exchange, but Nikolai is not in that camp 😄 📊 Define a ViewDefinition, point it to a FHIR server and extract a nice set of square tables. Nice playground here: sql-on-fhir.org/extra/playground.ht…

At #HospitalsOnFHIR session this afternoon, Filipe Mealha explains the national platform SPMS (as part of the Ministry of Health) builds for sharing electronic health data between healthcare providers in Portugal 🇵🇹 #EDHS helps, but national infrastructure and procedures are needed on top.

Rutt Lindström showcases the proposed structure for HL7 Europe guides. A nice guidance for anyone building an Implementation Guide on what sections are important to include! One column is hidden now, with "IHE-like requirements" like Use Cases, Actors and Transactions. #FHIR #HL7Europe #IHE

FHIR implementation can be easily underestimated, as Richard nicely illustrates: www.linkedin.com/feed/update/... 📈Vertical axis: Which and how many resources involved 📉Horizontal axis: Which existing tools to leverage for development, for publishing and which underlying standard
