With additional resources in R6 we can slow down the release cycle of the core FHIR specifications, but we can still incubate resources for new data areas at their own pace.

AI and LLM integration are one big challenge in #digitalhealth that promises to unlock many things. Huge progress is happening but cost (time and money) are still a big hurdle to reach usable solutions.

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.

AI? Letโ€™s first talk about FHIR, SNOMED, quality, and bias | ICT&health Global Interoperability is foundational for AI in healthcare. Most AI applications are currently still siloed, developed, and deployed within individual institutions.

โ€œAI isnโ€™t the first step โ€” data is.โ€
Dr. Carina Vorisek stresses the need for FHIR, SNOMED and clean, structured data before AI can truly support healthcare. #Healthcare #AI #FHIR #SNOMED #digitalhealth #interoperability
