Alternative Therapies are used instead of conventional or mainstream medical modalities.
Complementary Therapies are used in conjunction with conventional or mainstream medical modalities.
![Page 5: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/5.jpg)
Non-traditional Therapies
Ever increasing numbers of health care consumers are using nontraditional treatment modalities.
![Page 6: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/6.jpg)
Roots of Nontraditional Therapies
Ancient Greece: massage, art therapy, herbal therapy.
The Far East: energetic-touch therapies.
China: acupuncture, herbalism. India: Ayurvedic medicine.

![Page 9: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/9.jpg)
Mind-Body Medicine and Research
The traditional medical model is founded on the belief that the mind, body, and spirit are separate entities. A relatively new field of science, however, is called: Psychoneuroimmunology.
![Page 10: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/10.jpg)
Psychoneuroimmunology
The study of the complex relationship among the cognitive, affective, and physical aspects of humans.
![Page 11: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/11.jpg)
Body-Mind
The inseparable connection and operation of thoughts, feelings, and physiological functions.
![Page 12: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/12.jpg)
Holism and Nursing Practice
As a healing facilitator, the nurse enters into a relationship with the client and can be a:
• guide.
• change agent.
• instrument of healing.
![Page 13: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/13.jpg)

Using Alternative & Complementary Therapies
Have a non-judgmental attitude. Ask clients if they use nontraditional therapies. Get instruction in these therapies before trying
to administer them. Try one or two basic therapies (e.g. massage or
guided imagery). Discuss a therapy with the client before using it.
![Page 15: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/15.jpg)
Common Elements of Alternative & Complementary Interventions
The whole system is considered. The person is integrated and related to the
surroundings. There exists some life force or energy to be
used in the healing process. Ritual, prescribed practice and skilled
practitioners are vital to holistic healing interventions.

The Placebo
Historically, an inactive or innocent management contrivance to encourage healing in the absence of specific therapeutics
Relied upon to ‘control’ for nonspecific effects that might confound calculation of the true benefits of a novel intervention

Key Principles of CAM ResearchKey Principles of CAM Research
• Use the same designs and outcome instruments as for definitive studies of conventional practices
• Randomized, double-blind controlled trials are the ‘gold standard’
• Some modalities can not be blinded• Studies of whole CAM ‘systems’ require
creativity and flexibility• CAM experts and patient advocates should
be included in study design and oversight
![Page 71: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/71.jpg)
Designing CAM StudiesDesigning CAM Studies
Individual botanical or nutritional supplements can be tested in randomized, double-blind controlled trials.
Combinations of agents, especially if custom-tailored for each subject are harder to blind.
Complex CAM systems and physical modalities, among others, can not be blinded
It is hard to study the approach of an individual practitioner

Requirements for Ethical Research
Social value Scientific validity Fair subject selection Favorable risk:benefit ratio Independent review Informed consent Respect study subjects
Emmanuel, Wendler & Grady, JAMA, 2000
![Page 81: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/81.jpg)
Ethical Issues Posed by CAM
Social value Extensive public use without proof Emerging evidence questions traditional
assumptions of safety and efficacy
Scientific validity The literature is dominated by under-powered,
poorly designed studies, conducted by people with limited scientific credentials
![Page 82: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/82.jpg)
The plural of anecdoteis not evidence

Critique of Ongoing CAM Research
Sets a higher standard than for conventional practices – few allopathic practices are proven with double-blind RCTs
Is too reductionistic – CAM is multi-modal Does not test the approach as traditionally delivered
– wrong herb; wrong dose; wrong needling point … The investigators have no expertise in CAM
![Page 84: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/84.jpg)
Ethical Issues Posed by CAM
Fair subject selection Advocates and skeptics refuse enrollment,
comply poorly and withdraw prematurely These biases risk the generalizability of the
study findings Risk:benefit ratio Lack of formal preclinical and clinical data
challenges assumptions of safety, optimal dose and schedule
![Page 85: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/85.jpg)
Ethical Issues Posed by CAM
Independent review IRBs may oppose or lack expertise in CAM
Informed consent Undermines expectations of healing Difficult to inform where objective data on potential
risks and benefits are lacking
Respect for subjects Cannot ethically study everything to which a person
is willing to be subjected
![Page 86: Alternative Healing. National Center for Complementary and Alternative Medicine NIH, DHHS Evaluation of Complementary and Alternative Therapies.](https://reader035.fdocuments.us/reader035/viewer/2022081514/56649dd15503460f94ac6bdc/html5/thumbnails/86.jpg)
