Background
• A two year RAND Health study completed in Spring 05
• Results appear in 2 articles in September 05 Health Affairs and 4 RAND reports
• Funded by the private sector -- Cerner Corp., General Electric, Hewlett-Packard, Johnson & Johnson, and Xerox
• 14 member steering group headed by Dr. David Lawrence, former CEO of Kaiser

A6387b-3
The Problem in Context• U.S. health care is one of the largest and most
inefficient information enterprises because it still operates mostly with paper records
![Page 4: Can Information Technology Transform Health Care? Potential Health Benefits, Savings and Costs Richard Hillestad, Ph.D. Presented at The HIT Symposium,](https://reader035.vdocuments.site/reader035/viewer/2022070410/56649f055503460f94c1967f/html5/thumbnails/4.jpg)
A6387b-4
• U.S. health care is one of the largest and most inefficient information enterprises because it still operates mostly with paper records
The Problem in Context
• Despite health spending of $1.7 trillion nationally and projected to grow to over $4 trillion in 10 years, it doesn’t provide the best care
– recommended care is provided only about 55% of the time
– and, by a number of measures, health in the U.S. is worse than OECD averages
![Page 5: Can Information Technology Transform Health Care? Potential Health Benefits, Savings and Costs Richard Hillestad, Ph.D. Presented at The HIT Symposium,](https://reader035.vdocuments.site/reader035/viewer/2022070410/56649f055503460f94c1967f/html5/thumbnails/5.jpg)

• U.S. health care is one of the largest and most inefficient information enterprises because it still operates mostly with paper records
The Problem in Context
• Despite health spending of $1.7 trillion nationally and projected to grow to over $4 trillion in 10 years, it doesn’t provide the best care
– recommended care is provided only about 55% of the time
– and, by a number of measures, health in the U.S. is worse than OECD averages
• How much could Electronic Medical Record Systems (EMR-S) help?
![Page 6: Can Information Technology Transform Health Care? Potential Health Benefits, Savings and Costs Richard Hillestad, Ph.D. Presented at The HIT Symposium,](https://reader035.vdocuments.site/reader035/viewer/2022070410/56649f055503460f94c1967f/html5/thumbnails/6.jpg)
A6387b-6
What Is an Electronic Medical Record System?
• EMR -- replaces the paper medical record
• EMR-S adds functions:– Clinical decision support– Patient tracking and reminders– Personal health records– Computerized physician order entry– Regional health information networks
![Page 7: Can Information Technology Transform Health Care? Potential Health Benefits, Savings and Costs Richard Hillestad, Ph.D. Presented at The HIT Symposium,](https://reader035.vdocuments.site/reader035/viewer/2022070410/56649f055503460f94c1967f/html5/thumbnails/7.jpg)
A6387b-7
Key Findings
• Efficiency savings enabled by EMR-S could reach ~$80B/year at 90% adoption
• Costs to achieve that in 15 years average ~$8B/yr
• Safety benefits include avoiding 2.2 million adverse drug events
• Health benefits from prevention and management of chronic diseases alone could be 400,000 deaths avoided and 40M added workdays
• The market is not leading to this result because of important barriers and disincentives
• Therefore, there is a clear role for government action

A6387b-10
The RAND Study of EMR-S• RAND study developed computer simulation models
to estimate potential benefits and costs, assuming– Widespread adoption (90%)– Interoperability (across providers)– Related health care process changes, for
example:• Restructured hospital and physician office
workflow• Increased preventative interventions• Team care for chronic disease
• Extrapolates limited published evidence of EMR-S benefits
![Page 11: Can Information Technology Transform Health Care? Potential Health Benefits, Savings and Costs Richard Hillestad, Ph.D. Presented at The HIT Symposium,](https://reader035.vdocuments.site/reader035/viewer/2022070410/56649f055503460f94c1967f/html5/thumbnails/11.jpg)
A6387b-11
• Reduced waste, e.g., reduced duplication of tests
• Improved/changed processes, e.g., improved workflow and patient flow
• Fewer resources, e.g., reduced administration of paper records, better antibiotics usage
• Lower cost substitutions, e.g., generic drug utilization

Health Benefits Enabled by EMR-S
• Improved compliance with prevention activities
• Better management and prevention of chronic diseases
• Coordination of care across providers
• Patient involvement in care and healthy life style

A6387b-22
Chronic Disease Management Is a High Leverage Application of EMR-S
• The chronically ill absorb about 75% of national health expenditure
• Chronic disease management requires– Community support and team care– Coordination and communication across
providers– Patient monitoring and involvement
• Regional demonstration projects with EMR-S often focus on chronic disease management

A6387b-28
The Government Should Intervene Now
• The market is not working well – Providers have little incentive or capability to
institute standards-based, interconnected EMR systems
– Current adoption process may lead to a 2-tiered health care system and inhibit future change
• The government is the largest employer and health care payer (and has considerable leverage on the industry)
• EMR-S enabled changes could moderate unsustainable health care cost growth and improve quality
![Page 29: Can Information Technology Transform Health Care? Potential Health Benefits, Savings and Costs Richard Hillestad, Ph.D. Presented at The HIT Symposium,](https://reader035.vdocuments.site/reader035/viewer/2022070410/56649f055503460f94c1967f/html5/thumbnails/29.jpg)
A6387b-29
Key Government Actions
• Promote standards and EMR-S certification
• Implementation support
• Promote interoperability and regional connectivity
• Medicare leadership with incentives– Pay for use of EMR-S– Pay for quality measured by EMR-S

Can Information Technology Transform Health Care?
• Yes, but --– not without much wider adoption– not without standards and interoperability– not without associated process and health care
system changes– not without measurement of quality and
efficiency
• And, probably not without government intervention
