Health trends

Health Trends

  • Today’s most popular health trends:

        (American Society for Aesthetic Plastic Surgery)

    • Pharmaceuticals

      • People are increasingly relying on pills to fix their health problems

Fad diets and the fda

Would these health trends be so pervasive in society if the public had more factual information?

Health information for the public

Health Information for the Public

  • The role of the information professional:

    • What we can do:

      • Facilitate the discovery of quality, reliable information

      • Help people think critically about health information and their sources

      • Guide people to be more proactive in their own health care

    • What we can’t do

      • Make decisions for health consumers about their own health choices

Common sources of health information

Common Sources of health information

  • The Internet

  • Family and Friends

  • Physician/Health care provider

  • The medical literature

    • Language is difficult

    • Health consumers now have a wealth of medical information written for them

Evaluating the fda s findings

Evaluating the FDA’s Findings

  • The GOOD

    • Multidisciplinary scientific oversight

      • Anesthesiologists, pathologists, epidemiologists, oncologists etc…

    • FDA studies claim to be all inclusive

      • All patient records are included, nothing (that we know of) is left out of their studies

  • The BAD

    • The FDA’s recommendations are confusing/ambiguous

    • Lack of consistency in recommendations

    • Information on the Web site is dated

  • The Ugly

    • Inamed and Mentor (Manufature wars) make it difficult to determine what the FDA’s position is

Drug approval and marketing

Drug Approval and Marketing

  • FDA Drug Approval Process

    • Center for Drug Evaluation and Research(CDER) http://www.fda.gov/cder/index.html

    • Evaluates all new drugs before they are sold

      • Prescription and over-the-counter

    • Ensures “that drugs are safe and effective”

    • “It is the responsibility of the company seeking to market a drug to test it and submit evidence that it is safe and effective.”

Fda approval

FDA Approval

New drug identified as potentially effective:

  • Laboratory studies

  • Animal testing

  • Clinical Trials

    • FDA guidelines and regulations for trials

    • Institutional Review Boards (IRB) – ensures trial safety

    • Ethical and scientific quality standards

  • Apply to FDA/CDER for approval

  • FDA Review

Fda approval1

FDA Approval

  • Clinical studies carefully examined

  • Input from advisory committees

  • Drug must be proven safe

  • Drug must prove effective for intended use

  • Benefits of drug must outweigh known risks

Fda approval2

FDA Approval

  • Potentially effective process

  • Clinical trials done by medical schools, academic health sciences centers, research centers

  • Advisory committees provided FDA with independent opinions, recommendations



  • 1980 – Bayh-Dole Act

    • Created uniform patent policy among many federal agencies funding research

    • Universities can retain ownership of inventions produced by federally funded research

    • Designed to speed the commercialization process, improve technology transfer

    • Drug companies can now use university researchers to do drug development, as well as drug trials



  • 1980 – Bayh-Dole Act – continued

    • Transformed the perspective of academic medical centers

    • Became “partners” to industry with potential for financial gain

    • Faculty encouraged to patent their discoveries

    • University patents sold to drug companies bring financial rewards for publicly funded research

    • Drugs developed and tested at academic sites



  • Hatch-Waxman Act – 1984

    • Extended the patent rights for brand-name drugs

    • Extended exclusive marketing rights

    • Effective patent rights increased from 8 to 14 years

    • Added billions to sales for drug companies

Fda approvals

FDA Approvals

  • Government-granted monopolies

    • FDA approval grants exclusive marketing rights

    • Patents prevent generics from infringing on market share

  • In 2002, FDA approved 78 drugs

    • Only 7 of these were classified as improvements over existing drugs

    • Other 71 simple variations of older formulas

    • New patent for old drug

    • Further exclusive marketing, more profit

Drug development costs

Drug Development Costs

  • Drugs are the fastest growing part of the nation’s health care bill

  • Biggest drug companies spend ~14% of budget on Research & Development (R & D)

  • Same drug companies spend ~31% on marketing

  • Big drug companies make more in profit than they spend on R & D

Drug development and testing

Drug Development and Testing

  • Much of the R & D done at universities with federal funding

  • Clinical trials funded by drug companies, carried out at universities

  • Schools and faculty engaged in clinical trials receiving payment from drug companies

  • Contracts may prevent dissemination of results

    • Unfavorable results not published

    • Sharing information with colleagues prohibited

  • Drug company consultants may sit on FDA advisory committees

    • Potential for conflict of interest
