Decision Making for Patients and Providers

• Access to (electronic) health records generates information needs

• Information needs go unmet

• “Best evidence”, educational material, training programs can address these needs

Infobutton: Automating the Process

• Questions can be anticipated

• Match information source to question

• Automate the retrieval

• Query can use patient information

Smarter Retrievals from the Record

• Repository stores events and results

• Clinical problems at a different level of granularity

• Re-use knowledge to map from problems to clinical data

• Produce problem-specific views of the medical record

Summary

• Terminology translation facilitates retrievals• The Web makes the rest easy• Further study needed:

– When do nurses need information?– What information do they need? – What terminology is needed?– What are the right resources?– How can retrievals be facilitated?– How do we present results?
