In this episode of 4x4 Health, we talk to Grahame Grieve, the architect-developer of HL7s Fast Healthcare Interoperability Resources (FHIR) and principle at Health Intersections of Melbourne, Australia.  Grahame is one of the world’s foremost experts on healthcare interoperability, a strong leader of the Health IT community, and is sometimes referred to as the ‘Father of FHIR.’ “[Interoperability] is not a technology problem . . . It’s an information and people problem”, Grahame observes before describing how FHIR was able to break through this 'people problem' by using a collaborative and community driven approach. Grahame's passion for improving healthcare outcomes with technologies like FHIR shines throughout the episode. We think you will leave this episode inspired and optimistic about an interoperable future for healthcare.
