Outline
Economics of Bulk Purchasing and Formularies
International perspectives
Why the existing systems have problems
Why do other countries pay lower prices for drugs?
Opportunities for Medicaid
Market power using price transparency
Comparative effectiveness
Economics of Bulk Purchasing
and Formularies
Single purchaser/single decision maker
Wal-Mart directly purchases billions of cans of
dog food
Wal-Mart limits consumer choices to a few
brands of dog food
Medicaid is not a single bulk purchaser
Does not directly purchase drugs
Cannot interfere with practice of medicine
OBRA 90 prohibits formularies
Other Countries Use Bulk
Purchasing and Formularies to
Obtain Lower Prices for Drugs
Drug prices are roughly half US prices
They use multiple strategies to determine
what specific drugs they will purchase
including:
Bulk purchasing
Formularies
National Institute for Clinical
Effectiveness (NICE)
Advises National Health Service (UK) on which
drugs to purchase
Objective is to recommend the lowest cost
therapeutically equivalent drug
Not top 3 drugs in same class
Not 150% of lowest price
Employs comparative effectiveness criterion
Compares costs of different drugs
NHS negotiates to buy one drug in bulk
Options for Medicaid
Price transparency
Better preferred drug lists
Price Transparency
Rebates are difficult to monitor
Is the state actually getting the appropriate rebate?
Instead compare the prices that different
entities pay for the same drug
Medicaid versus Canada
Medicaid versus VA
California versus Maryland
Maryland Medicaid versus Maryland Prisons
Price Transparency Examples
Drug A price
$1.00
$1.10
$1.05
$1.05
$1.06
Canada
VA
Maryland Medicaid
California Medicaid
California Prisons
Drug B Price
$1.00
$1.15
$1.25
$1.50
$2.50
Canada
VA
Maryland Medicaid
California Medicaid
California Prisons
Use the Bully Pulpit
Begin by identifying specific drugs where state
agencies are paying much higher drug prices
Use information to question drug companies on
the specific prices they are charging
Most drugs are probably more like Drug A than
Drug B
Use Bully Pulpit on Drug B
Preferred Drugs Lists
Offer much greater potential for obtaining
cost reductions than bulk purchasing
Drugs on preferred drug list are more likely to
be prescribed – similar to bulk purchasing
Savings depend of quality of preferred
drugs list and willingness/ability to exclude
drugs
Legislative changes may be needed
Technical Challenges in
Developing Preferred Drug Lists
Medicaid is not in the pharmacy business
Technically difficult to do comparative
effectiveness studies
Each patient is different
Most clinical trials exclude complex patients
Few head to head comparisons of drugs
Costs are difficult to measure
Each Patient is Different
The same antibiotic would not necessarily
be given to a healthy 20 year old with a
cut on his leg to a frail 80 year old with a
cut on her leg
Patient tolerance for drugs depends on
age, health status, other medications, etc.
Most Clinical Trials Exclude
Complex Patients
To get a drug approved by the FDA it is
necessary to demonstrate safety and
efficacy (not effectiveness)
It is easiest to demonstrate safety and
efficacy in uncomplicated patients
As a result most clinical trials exclude complex
Medicaid patients
Limited evidence base for making drug
decisions
Post Marketing Surveillance
Few studies compare effectiveness in
actual patients
Few studies compare the relative
effectiveness of different drugs
Lack of effectiveness studies makes creating
preferred drug lists very difficult
Cost Effective
Least expensive is not necessarily the
least costly
Lower rehospitalization rates
Costs are difficult to measure
Direct (medical)
Indirect (transportation)
Measuring Effectiveness
Difficult to measure
What is the purpose of medical care
Example – cataract operation
Improve visual acuity (20/20)
Improve visual functioning (read street signs)
Improve quality of life ( drive at night)
Three measures not always highly correlated
Multiple Entities in US Conduct
Comparative Effectiveness Studies
VA
AHRQ
CMS
NIH
BC/BS
Kaiser Permanente
Drug Companies
Medicaid
What Data Should States Use
to Create PDLs
Each state should not conduct its own
studies
Too expensive
States should not rely on drug company
studies
Potential for bias
States Need to Information from NIH,
AHRQ, and CMS to create PDLs
Congress needs to appropriate more money
for comparative effectiveness research to
help states
Conclusion
Drug companies need economic reason to give a
real discount
Drug companies unlikely to give discounts for
drugs unless the state is the actual buyer
Without an economic rationale, drug companies will
attempt to find ways to “game” the system
Full employment for Attorney Generals
State could become bulk purchaser for all drugs
PDLs offer promise but comparative
effectiveness studies need to be improved and
more restrictive preferred drug lists are needed
