               Pharmacy
                                   Current Status
 • At the ISPOR Seoul meeting in 2008 nearly
   every Asian country indicated they use a
   version of Health Technology Assessment in
   making drug use reimbursement and
   formulary decisions.
 • In most countries these decisions are made
   without considering cost effectiveness.
 • Pharmacoeconomic based Health
   Technology Assessment is growing but small

  (2009)

                Australia
• Universal Health Insurance since 1984
• Government supports
  • Medicare
    • Hospitals
    • Providers (Physicians and Others)
  • Pharmacy Benefits Scheme (PBS)
    • All residents are eligible
    • Lower co-pays for low income patients
                Australia
• PBS established by the National Health
  Act of 1953 and ammendments
  • Objective – To provide access to life
    enhancing medicines at an affordable price
    taking into account effectiveness, cost and
    cost-effectiveness of medicines
  • The Government may negotiate prices
                 Australia
• Pharmacy Benefits Advisory Committee
  (PBAC)
  • Provides advice to the Minister of Health
  • Considers
    • Clinical Effectiveness
    • Safety
    • Cost Effectiveness
  • Mandatory submission of economic
    information by manufacturers
                      Australia
• PBAC Economic Guidelines
  • Societal Perspective
  • Only direct costs required
  • Must include
     • Comparison with treatment to be replaced
     • Evidence of effectiveness
     • Incremental and Sensitivity Analyses
  • Strong Preference for
     • Head to head trials
     • Cost Utility Analyses
• Coverage provided for new drugs that are being
  considered for PBAC listing
                     Australia
• Evaluation of submissions to PBAC (1994-
  2004, N=858) that included QALY’s gained
  (N=116) or Life Years gained (N=138)
• Compared to average submissions, the
  change in likelihood of coverage was
  • Clinical significance +21%
  • Life threatening conditions +38%
  • Increase of $A10,000 from mean value of
    $A46,400 -6% in incremental cost/QALY

             Harris AH, 2009
              Taiwan
• Population
  22,805,547
• GDP $738.8
  billion
• GDP Per Capita
  $31,900
                       Taiwan
• Social health insurance modeled after Japan and
  Germany
• NHI Scheme 2005 - Single Payer system
• Health Care 6.1% of GDP (2006)
• Center for Drug Evaluation (CDE) established 2007
   – Provides evidence of comparative effectiveness and cost
     effectiveness
   – Dossiers submitted to CDE undergo independent scientific
     assessment with additional input from the medical
     associations.
   – Committee members and opinion leaders from medical
     associations serve as an external advisory board
• Bureau of NHI uses HTA evidence for listing and
  reimbursement
                         Taiwan
• Deliberations and discussions are not made public
• Data submitters have opportunity for input
• Data submission is voluntary
• A guideline for submission exists (GMSPE) but it is
  not official
• Industry believe that conducting PE studies and
  confirmation of CE should guarantee a higher price
• Resource allocation depends more on negotiations
  than HTA evidence (Huang, N, Pricing and Reimbursement
    Meeting, Bangkok, 2008)
           South Korea
• Population
  48,379,392
• GDP $1.344
  trillion

  Insurance system in 1989
• Operated at a deficit
• Guidelines for Economic Evaluation of
  Pharmaceuticals in Korea (KPEG)
• Policy using economic evaluation data in
  making drug reimbursement decisions (2006)
• Positive List System (PLS) created in 2008.
  Lists covered drugs selected utilizing economic
  evaluation data.
                South Korea
• Prior to the PLS
  – Large number of drugs on reimbursement list
     • 21,000
     • Cost effectiveness and budget impact rarely
       considered
     • Contained many substitutable drugs and a large
       number of small and medium sized companies
       competing strongly
  – Quick Adoption
     • Second in the world to review 25 of 61 new drugs in
       2003
     • Lack of adequate clinical and pricing data available
                South Korea
• All new drugs – PE HTA
• Existing drugs evaluated over time
• HTA Implementing Organization (HIRA)
  •   Company submits PE data
  •   Staff critique and prepare HTA report
  •   Reviewed by government appointed expert panel
  •   Concerns about bias, transparency, and staffing
  •   78 drugs evaluated from January 2007 to June
      2008
          South Korea
• Detailed information shared between HIRA
  and manufacturer but is not published
• ICER threshold is a key criterion used
             Thailand
• Population
  65,905,410
• GDP $553.4 billion
• GDP Per Capita
  $8,500
               Thailand

  Health

  on efficacy, safety and quality
• Public health insurance pays for NLEM
• Public sector drug prices negotiated at
  central and hospital levels.
• Ministry of Commerce – price controls

  • Introductory and Advanced training in economic
    evaluation issues provided
  • Working to increase staffing and infrastructure
  • Completed ~12 HTA evaluations
  • Revision of NLEM in 2008 was the first time that
    pharmacoeconomic evidence played an official role in
    designing reimbursement
               Conclusions
•   Four countries
•   Four strategies
•   Some more advanced than others
•   All have made significant progress
•   We can all learn from their organization,
