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

RCT Randomized Clinical Trials
Efficacy and safety in a small population with a restricted study protocol
Real world information to make health care decisions for large populations within defined budgets

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

UU Patient Centered Retrospective Research Registries
• Collaboration with University of Utah: – 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
