Complementary and Alternative Medicine (CAM)
A group of diverse medical and health care systems, practices, and products that are not presently considered to be part of conventional medicine
Healing therapies that typically fall outside the Western biomedical model of disease, diagnosis, and treatment

Complementary and Alternative Medicine (CAM)
The list of what is considered to be CAM changes continually as those therapies that are proven to be safe and effective become adopted into conventional health care and as new approaches to health care emerge
![Page 5: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/5.jpg)
Why do people use CAM?
Desire for health and wellness (1) Prevention Cancer- recent estimate 83% (2) Pain
Musculoskeletal pain Back and neck pain
![Page 6: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/6.jpg)
Who uses CAM? Kessler 2001
Surveys show large increase in past 50 years in U.S. and other industrialized countries
Eisenberg 1998 Between 1990 to 1997, increase from 34% to 42% of US
households reporting CAM use Barnes 2004
In 2002, 75% of U.S. adults reported use of CAM in lifetime and 62% in past 12 months (when prayer included)
![Page 7: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/7.jpg)
Who uses CAM?
![Page 8: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/8.jpg)
Who uses CAM?
Palinkas 2000 Surveys of primary care clinic populations
show 28-47% utilization of CAM 21% of patients in primary care practices
reported using CAM for the same health problem for which they sought conventional care on that visit
![Page 9: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/9.jpg)
Who uses CAM?
Chiropractic and massage are most frequently used practitioner-based CAM therapies (1). An estimated 8-17% of US population visits a
chiropractor each year, 33% over lifetime. About 1/3 of US population reports having ever
had a therapeutic massage. Individuals in rural and underserved
communities are particularly likely to use chiropractic care (2).
![Page 10: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/10.jpg)
4 Reasons for Improvement
In general, four reasons why people improve: Effective treatment Illness improved on its own Patient was misdiagnosed Patient expectations
Lets take a closer look at this one… The story of “Mr. Wright” (page 435-436)
![Page 11: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/11.jpg)
Placebo Effect
Talbot (2000) Placebos are at least half as effective for
controlling pain as are active drugs like aspirin and codeine
Blakeslee (1999) Placebos are just as effective as SSRI’s
![Page 12: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/12.jpg)
Is it biological as well???
Vincent and Furnham (1997) Classically conditioned
Benson (1996) “Remembered wellness”
Brody (2000) Placebos tap into the body’s natural “inner pharmacy”
Bendetto (1996) Interesting experiment in which researchers claim a
placebo enhanced the activity of endorphin release (see page 437)
![Page 13: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/13.jpg)
A closer look at the most widely used alternative treatments…
Acupuncture Mind-Body Therapies
Hypnosis Relaxation and Meditation Spirituality and Prayer
Chiropractic Naturopathic Medicine
![Page 14: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/14.jpg)
Acupuncture
Used for most common ailments – backaches, headaches, arthritis, allegies, muscles aches and spasms, etc. Shen Nung (Father of Chinese Medicine)
Qi Energy running through our body
14 main meridians Needles bring us back to homeostasis
Deqi Sensation is felt (not painful)
![Page 15: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/15.jpg)
Acupuncture
How does it work??? ???
Does it work? Chronic pain – yes Substance abusers – yes
How much research? A lot but unfortunately not without many limitations
Other issues… Good news: More insurance companies covering this Bad news: Conventional methods may be abandoned
![Page 16: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/16.jpg)
Hypnosis An altered state of consciousness brought on
by special techniques and that produces responsiveness to suggestions for changes in experience and behavior
Probably around since antiquity, the rediscovery of hypnosis is commonly credited to Franz Anton Mesmer
![Page 17: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/17.jpg)
Franz Anton Mesmer (1734-1815)
Mesmer would pass magnets over the bodies of ailing people, some of who would lapse into a trancelike state and then awaken much improved At the time many thought Mesmer’s work was linked to
quackery… Today skepticism remains as books on hypnosis is often
grouped with those on parapsychology, ghosts, and witchcraft
Nevertheless, most psychologists believe it to be a respectable topic for scientific study
![Page 18: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/18.jpg)
Can hypnosis work on anyone?
Can you be hypnotized against your will? Hypnotic Susceptibility
Degree to which a person responds to hypnotic suggestions
Willingness to be hypnotized is most important factorA key quality of hypnotically susceptible people is if
they can become deeply absorbed in imaginative activities (Fantasy-prone personalities)
Stanford Hypnotic Suggestibility Scale
![Page 19: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/19.jpg)
Can hypnosis alleviate pain?
Yes – this has been clearly established in experiments… Hypnotized subjects report far less pain than
others when their arms are placed in ice water
![Page 20: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/20.jpg)
Why?
2 Theories Selective Attention Theory Dissociation Theory
![Page 21: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/21.jpg)
Selective Attention Theory
We feel little or no pain because our thoughts are away from it – like the injured athlete who still completes the play or the person who refuses to look at that needle Aspects of the Gate Control Theory???
![Page 22: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/22.jpg)
Dissociation Theory: A divided consciousness?
A dissociation or split between different levels of consciousness – dissociating the sensation of pain with our emotional suffering Hilgard (1986): “the hidden observer”
![Page 23: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/23.jpg)
Reports of Pain in Hypnosis
![Page 24: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/24.jpg)
Relaxation and Meditation
Progressive Muscle Relaxation Active training in tensing and relaxing muscles
Mindfulness Meditation “awareness without thought”
Transcendental Meditation Focused awareness on a single object or word
(mantra)
![Page 25: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/25.jpg)
Spirituality and Prayer
Recent trend: Medicine and spiritual healing coming together
Does spirituality promote health? 80% in US say yes But scientific evidence is mixed
![Page 26: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/26.jpg)
Chiropractic
Chiropractic and massage are most frequently used practitioner-based CAM therapies An estimated 8-17% of US population visits a chiropractor
each year, 33% over lifetime. About 1/3 of US population reports having ever had a
therapeutic massage.
Individuals in rural and underserved communities are particularly likely to use chiropractic care For example: Chiropractors in every zip code region in
Kentucky
![Page 27: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/27.jpg)
Naturopathic Medicine
Herbal therapy Used by 12-14% of the US population, up from 2.5%
in 1990 (Kaufman, 2002) 16-18% of patients taking prescription medications
also take herbal remedies (Kaufman, 2002) Food Supplements
Strong evidence supporting benefits Dietary Medicine
Another strong link to better health as correct diet appears to cut down risk for most of major chronic illnesses (heart disease, strokes, some cancers)
![Page 28: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/28.jpg)
Naturopathic Medicine
Do they work? Again, studies show mixed results
![Page 29: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/29.jpg)
Why do people use CAM?
Very few individuals rely exclusively upon alternative modalities Most individuals who use CAM do so because
of preference and the perception that the combination of CAM and conventional treatments is superior to either alone
When conventional care is not relieving their symptoms.
![Page 30: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/30.jpg)
![Page 31: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/31.jpg)
Who practices CAM?
Wide variation in background and approach Diversity in training programs
Some weekend and/or distance learning certificate programs
Non-MD acupuncture programs require2,000-3,000 hours (4 year masters degree)
Chiropractic training involves 4 years beyond 2 or 4 years of college
No standardization of approach to accreditation and licensure Most require 300-500 hours and CEUs
Variations by type of practitioner and by state
![Page 32: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/32.jpg)
Who practices CAM?
Chiropractors Around 66,000 DCs in US Most accepted professional therapy Licensed in all states High patient satisfaction
Massage Therapists Over 46,000 AMTA members in US Most common CAM modality in hospital-
based programs Licensed in 2/3 of states
![Page 33: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/33.jpg)
Who practices CAM?
Increasing numbers of dual-trained practitioners… RNs
Holistic Nursing Certification Therapeutic Touch, Healing Touch
MDs American Board of Holistic Medicine American Board of Medical Acupuncture
![Page 34: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/34.jpg)
What about communication?
Eisenberg (2001) Between 40 and 70% of CAM users do not
disclose their use to their physician.
WHY?
![Page 35: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/35.jpg)
Why does this matter?
Kaufman (2002) The substantial overlap between use of
prescription medications and herbal supplements raises concerns about unintended interactions
Patient use of CAM is often a clue to values and preferences that need to be acknowledged
![Page 36: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/36.jpg)
Health psychologists role…
1. Always ask! “What else are you doing for your health?”
2. Be open and nonjudgmental.
3. Consider patient preferences and values.
4. Encourage self-monitoring of results.
Eisenberg 1997
![Page 37: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/37.jpg)
Health psychologists role…
5. Coordinate care as appropriate.
6. Be honest about your lack of knowledge and open to education.
7. Monitor safety and efficacy, arrange follow-up.
8. Document all discussions and advice.
Eisenberg 1997

Where are we now?
There is an urgent need for more and better trials of CAM therapies and the increased research suggests we are going in that direction
Research funding 1992 $2 M 2004 $117.7 M

![Page 39: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/39.jpg)
Where does this leave us?
Many conventional treatments have been adopted without good quality
research are costly are invasive are likely to have adverse effects
AND often provide inadequate relief
![Page 40: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/40.jpg)
Where does this leave us?
CAM interventions generally are low cost are low risk are free of serious side effects
AND are widely used
![Page 41: Health Psychology](https://reader036.fdocuments.us/reader036/viewer/2022062519/56814f92550346895dbd4fac/html5/thumbnails/41.jpg)

Framework for approaching CAMin clinical situations
Protect against dangerous practices Permit practices that are harmless and that
may help Promote and use practices that are safe
and effective Partner with patients and encourage
communication about CAM
