• Understanding Health Information

• Historic Problems & Solutions

• Current Challenges and a need for innovative solutions

Semantic Interoperability

Semantic Interoperability for EHR

• Information Exchange among Actors on-time– Information: must be meaningful, complete, up-

to-date, and use-full

– Exchange: information recipient must be able to interpret incoming information according to the source

– Actors: Systems, Devices, and Humans

– On-time: Notification in real-time and on-demand

Interoperability: Care Organization

Workflow: Care Organization

Patient is Registered / AdmittedProprietary Interfaces are used to notify hospitals departmental

Innovative Solutions

• Let people manage their health information• Develop and promote universal identifiers• Improve operation by refining workflows and

procedures • Standardize – refine existing standards but not reinvent

or-localize• Educate: track or use information for all actors• Identify and target source of truth for building a

normalized and complete EHR• Use proven technologies• Reduce dependencies and technical requirements
