Key Points
• Definition of Value
• The pros and cons of Real World Data
• Development of Patient-Centered
Retrospective Research Registries
(PCR3s) within our system
• Application to value assessment of new
technology
UHC Technology Reimbursement
Considerations under HCR
• Improving health care efficiency
• Improving health care quality
• Allocation of scare healthcare resources

Efficacy vs. Effectiveness
• Efficacy
– RCT
– High internal validity
– Limited generalizability
• Effectiveness
– Observational studies
– High external validity
– Lack of Controls

Information Technology and Bioinformatics
Utah Population Database
HCI/UHOSP investigators and clinicians
Enterprise Data Warehouse (EDW)
• Contain longitudinal data on patient cohorts from
1995 to current including clinical, survival and
charge data.
• Used to develop models to predict cost-effective
outcomes of new pharmaceuticals and diagnostic
tests

The Promise of Personalized Medicine
• Pharmacogenomic tests can fine tune
treatment pathways for patients with breast
cancer after surgery
– Stratify patients as to whether they should receive
treatment based on risk
– Stratify patients by which treatment would provide
the best response
• However these tests come at a cost that need
to be weighed against the benefit they can
bring to patients

• Assist researchers in development
• Assist payers in reimbursement decisions
• Assist patients in treatment decisions
Summary
• Development of Patient-Centered
Retrospective Research Registries
(PCR3s) are in process within our system
• These PCR3s can be applied to value
assessment of new technology for Health
Care Reform
