5Scope of Alternative Medicine
- Most of worlds population depends on it much
more than on scientific medicinewhich is often
unavailable or too expensive. - 20 billion industry in U.S.
- 75 paid out of pocket
- few of total U.S. healthcare bill
- more visits to alternative providers than to
primary care physicians - NIH National Center for Complementary and
Alternative Medicine - nccam.nih.gov
- 50 M budget
- (was 2 M in 1992 for OAM)
6David Eisenberg surveys (90, 97)
NEJM JAMA

- 21.2 B (12.2 B not covered by insurance)

8Aspects of Alternative Medicine
- ancient wisdom
- religious undercurrent
- New Age spiritualism
- faith healing
- empiricism (experientialism)
- substitute personal experience for scientific
knowledge - mysticism ( extreme skepticism)
- mind/body dualism
- often anti-science
- energy vibrations (red flag)
9Vital Force
- nonmaterial, divine, or personal form of energy
(or vibrations) - little or no relation to physics usage
- Qi (chi) chakras innate intelligence psychic
energy etc. - acupuncture Qi and body interact through
elaborate system of channels (nonexistent) - energy undetectable by instruments or objective
tests - only subjective
10Main Approaches
- Mind/Body
- biofeedback, relaxation, hypnosis,
- stress and emotions are known to play a role in
physical health - neuroimmunology new field
- Alternative drugs
- cancer treatments (shark cartilage!??)
- other herbal remedies
- Treatments at odds with Western medicine (and
science) - chiropractic, acupuncture, homeopathy,
11Considerations
- Most ailments (80) are self limiting!
- Many are psychogenic.
- Placebo effect is strong! (double blind?)
- Are A.M. treatments safe and effective?
- There are dangers in avoiding (or deferring)
mainstream medical care for serious organic
ailments. - How does one determine which treatments work, and
which do not? What is the evidence? and how
solid is it? - Beware quackery and con artists ().
12Placebo Effect Clinical Trials
- Placebo
- sugar (glucose) pill, saline injection, sham
treatment - surprisingly effective (typically 30-40!!)
- used as control in clinical trials
- Double-blind trials
- patient practitioner unaware of whether patient
receives actual drug or placebo - randomization encoded labeling
- statistical analysis (large studies preferred)
- expensive
- gold standard but not always possible
13Clinical Trial Phases (new drugs or treatments)
- Phase I safety, safe dosage range, side effects
( 50 subjects) - Phase II effectiveness and more on safety
(200 subjects) - Phase III confirm effectiveness, monitor side
effects, compare other drugs or treatments, plan
safe usage (2,000 subjects) - Phase IV continued study after it has gone to
market (incl. long-term side effects)
14Major Themes of A.M.
- spiritual healing
- yoga ayurveda
- natural healing
- naturopathy homeopathy
- hands-on healing
- acupressure, reflexology
- therapeutic touch (mostly hands off !!)
15Homeopathy
Samuel Hahnemann 1755-1843
- Law of Similars
- like cures like
- Law of Infinitesimals
- infinite dilution
- unaware of Avogadros number!
- Considered pseudoscience today
- but remains popular commercially successful
- placebo effect
- Note Sen. Royal Copeland, MD, sponsor of Food,
Drug, and Cosmetic Act (1938 FDA), saw to it
that homeopathic medicines were not included (re
safety effectiveness) Copeland was a
homeopath
16Therapeutic Touch
- Emily Rosa
- fourth-grade science fair project
- Could therapeutic touch practitioners actually
detect a human energy field? - Results No!
- published in JAMA
- JAMA 2791005-1010 (April 1, 1998)
17Conclusions(Rosa et al., 1998)
Twenty-one experienced TT practitioners were
unable to detect the investigator's energy
field. Their failure to substantiate TT's most
fundamental claim is unrefuted evidence that the
claims of TT are groundless and that further
professional use is unjustified.
