8. Cancer care and healthcare data are more and more complex!
Choices depend on :
• Patient Demographics & Preferences
• Cancer Diagnosis
• Labs, Vitals, Biomarker/Genomic Results
• Previous Treatments & Results
• Healthcare Coverage
• Clinical Guidelines
• Eligible Clinical Trials
9. Problem: Missed Learnings from millions of treatments :-(

11. A Clinical Data Repository for our CDS products
Why use the FHIR standard?
• Support a CDS application ecosystem.
• One consistent source and view of clinical data.
• Future proof interoperability and other regulations.
• International cross-functional consensus process.
• Solid foundation yet flexible.
12. • Information models
• Constraints
• Terminology
• Usage

13. Adopting FHIR
Defining our Data Model
• FHIR Resources designed with the 80/20 rule.
• Customization and extension for specific use cases.
• Few implementation guides.
• Understanding the clinical domain.
• Solid logical modeling and profiling exercise.

• Many standards.
• Mapping/transcoding.
• Enabling Named Entity Recognition.
