Alternative medicine
From Wikipedia, the free encyclopedia.

The neutrality of this article is disputed.

Alternative medicine is a broad term for any method of medical treatment that stands outside the framework of mainstream conventional medicine (compare evidence-based medicine).

It is worth noting that practitioners of some treatments and techniques (for example, hypnosis, acupuncture) often described as 'alternative' are, in fact, accepted by the mainstream, and are not regarded as alternative by many in the mainstream. The often bitter conflict between the more extreme partisans on both sides does not reflect the reality of a modern health system. Also, the definition of what is and isn't 'alternative' constantly changes, generally as result of research. It is not a fixed category.

While alternative medicine is usually supposed to replace conventional treatments, the combination of alternative and conventional medicine is referred to as complementary medicine. The term Integrative medicine was invented by Andrew Weil, MD and is said to refer to "the best of both conventional and complementary medicine". Collectively, all theses variations on alternative medicine is often referred to as complementary and alternative medicine (or simply as CAM).

Overview

Some kinds of alternative medicine can be practiced by the individual without the need for working with an alternative medicine practitioner. Others need to be carried out though alternative medicine clinics, GPs or businesses which advertise such services. When the service is performed by a conventional physician it is called complementary or integrative medicine.

Legal jurisdictions differ as to which branches of alternative medicine are legal, which are regulated, and which (if any) are provided by a state health service. Some practitioners and branches of alternative medicine have been investigated by state or national agencies for health-related fraud (commonly known as quackery), and in a few cases criminal charges have been brought.

Branches of alternative medicine

The most often used branches of alternative medicine in the United States are (Eisenberg et al, 1998):

  1. acupuncture
  2. biofeedback
  3. Chinese medicine
  4. chiropractic
  5. homeopathy
  6. hypnosis
  7. massage therapy
  8. naturopathy

Psychologists provide alternative medical services when they use biofeedback, hypnotherapy, or cognitive behavior therapy to treat a medical condition. There is a relatively new field in psychology called Health psychology.

Other branches of alternative/complementary medicine include:

Support for and concerns about alternative medicine

Support

Advocates of alternative medicine point to a number of different general arguments that tend to support the validity of using alternative methods of treatment to treat specific medical conditions.

  1. Edzard Ernst writes in the Medical Journal of Australia that: "About half the general population in developed countries uses complementary and alternative medicine (CAM). Yet many conventional healthcare professionals refuse to take CAM seriously; one often-voiced argument is "there is no research in CAM". Certainly, for some modalities there is no compelling evidence base, and some of the research into CAM has methodological flaws and biases. On the other hand, many doctors and medical educators are uninformed about the quality evidence that does exist." (Ernst, 2003)
  2. A search on PubMed reveals that there are over 370,000 research papers classified as alternative medicine published since 1966 in the National Library of Medicine database (such as Kleijnen 1991, Linde 1997, Michalsen 2003, Gonsalkorale 2003, and Berga 2003). There are no publicly available statistics on exactly how many of these studies were controlled or double-blind peer-reviewed experiments. They were, however, all published in research journals recognized by Medline.
  3. The question of the effectiveness of various alternative medicines has to be considered independently for each method, as well as for each medical condition or disease treated. It is not valid to lump them all together as one. When exploring the individual branches of alternative medicine several questions need to be answered in order to decide if the method is valid or quackery
    1. What is the method of treatment utilized?
    2. What are its therapeutic effects?
    3. What medical conditions does it effectively treat?
    4. What modes of action could plausibly account for these therapeutic effects?
    5. What harm, if any, could result from this treatment?
  4. In the United States, the National Center for Complementary and Alternative Medicine, a division of the National Institutes of Health, provides funding and other support for research in alternative medicine. This neither approves or negates CAM, as the NIH often funds speculative research that eventually has no practical value. It does, however, show that there is serious academic research being pursued, without outright dismissal into the questions raised by CAM.
  5. Physicians that are subject to the disciplinary actions of the state licensing boards do in fact offer alternative medical services to their patients. Hence, these physicians must see some added value in these alternative forms of treatments for their patients.
  6. Medical colleges like the University of Arizona, College of Medicine do in fact offer training in alternative medicine. As an example, the University of Arizona, College of Medicine, under the leadership of Andrew Weil, M.D., offers to practicing physicians a program in Integrative Medicine. In this fellowship physicians are trained in various branches of alternative medicine. Their training program "neither rejects conventional medicine nor embraces alternative practices uncritically."
  7. Some of the strongest support for the value of clinical experience in alternative medicine comes from conventional physicians who have voiced their criticisms of evidence-based medicine (Tonelli 2001, Downing 2003). These physicians, while arguing about their need to apply population evidence to the patient standing before them, are in effect supporting the value of eclectic branches of alternative medicine which place great value upon the clinical experience of the practitioner.
  8. The boundary lines between alternative and mainstream medicine have changed over time. Methods once considered alternative have later been adopted by conventional medicine as physicians gradually incorporate effective branches of alternative medicine of treatment in their conventional medical practices. Supporters of alternative methods suggest that much of what is currently called alternative medicine will be similarly assimilated by the mainstream in the future. Critics support a view that any medicine that can be proven is destined to be implemented in the name of the common good, so provable CAM will eventually be implemented.
  9. Alternative medicine offers additional choices to the buying public, to have treatments that are simply not available from conventional medicince. This argument covers a range of topics, such as patient empowerment, alternative methods of pain management, treatment methods that support the Bio-psychosocial model of health, and finally some patients are specifically in search for cures for their specific health concerns, stress reduction services, and other preventative health services that are not offered in some conventional medicine.
  10. Any positive effects on patients, even if only based on placebo effects, still provides benefits to overall patient health that traditional medicine may not have provided.
  11. The scientific basis of alternative medicine is not as bad as the critics represent it to be (Ernst 2003) because conventional medicine in reality has not been as science-based as it is publicly represented to be (Zalewksi 1999). Michael L. "Millenson decries the lack of scientific-based medical practice and medicine's failure to wake up due to its own historical studies. He cites data that 85% of current practice has not been scientifically validated despite medicine's claims of the physician-scientist." (Gunn 1998) Alternative medicine proponents argue that the mere fact that evidence-based medicine is being promoted speaks historically to a practice of medicine that was not completely based on science.
  12. Social critic Ivan Illich believes that Western and alternative medical practices are generally equally effective, for two reasons. First, Western practices are more effective at dealing with illnesses caused by microbes, whereas alternative practices are more effective at dealing with illnesses that are psychosomatic. Illich holds that Western and alternative practices are equally effective at dealing with illnesses that are self-limiting. (Illich 1976) In other words, Illich has suggested that conventional medicine treats illnesses that the human body would heal naturally all by itself without any form of treatment.
  13. A report, Crossing the Quality Chasm: A New Health System for the 21st Century, indicates that conventional medical practice tends to lag acceped medical knowledge by about 15-20 years. Thus, an alternative medicine technique could already be considered conventional, but physicians currently practicing either would not know about it or would not have he raining to use it.
  14. Because drugs can be patented, there is a strong incentive to study them, in favor of things which cannot be patented, such as vitamins, even if they may be less desirable.[1]

Concerns

The primary concern for those who do not support alternative medicine is that there is often no proper scientific verification that they actually work. Some of the studies cited in support of alternative medicine are not considered up to the normal double blind peer reviewed standard.

In the United States, conventional medicine is represented (some say dominated) by physicians at hospitals and medical schools. It is supported by state boards which rate and license professionals, and by the FDA which officially approves or disapproves drugs and some therapies.

Alternative medicine chafes at these restrictions and seeks to bring new ideas to the people more quickly than the established procedures allow, which sometimes results in conflict. Mainstreamers maintain that official oversight is needed to prevent quackery, while advocates of alternative medicine loudly protest that their contributions and discoveries are being unfairly dismissed, overlooked or suppressed.

In countries where healthcare is paid for by State or privately-funded medical insurance systems, alternative therapies are frequently not covered by these systems and these treatments are paid for by the patient. This leads to a concern that gullible or desperate people may be being exploited.

In addition, there is a concern that people may delay seeking conventional treatment, whilst they undergo alternative therapies. This may be dangerous to their health.

Finally, critics of alternative medicine are concerned that some branches are not properly regulated. This means that there is no external control on practitioners and no real way of knowing what training or expertise they may possess.

Science and alternative medicine

While mainstream conventional medicine is commonly thought of as relying on the scientific method for results, as stated above in one viewpoint, as much as 85% of current medical practice has not been scientifically validated. Large scale trials of new drugs which are usually funded by pharmaceutical companies are undertaken to see if they really are better than the alternatives. Medical research writing companies often ghostwrite drug research papers, which peer reviewed respectable journals like NEJM, Lancet, JAMA, and BMJ have been unable to prevent from being published (Flanagin 1998, Larkin 1999).

The science community argues that it is impossible to use testimonials, hearsay and mystical arguments as proof, because observer bias distorts recollection. The only way to counter observer bias is to run a double blind experiment, where neither the patient nor the practitioner knows whether the real treatment is being given or if a placebo has been administered.

Proponents of alternative medicine counter by saying that you cannot use existing testing methods for certain forms of alternative treatment methods. Furthermore, much evidence dismissed as hearsay in fact represents clinical experience. Many branches of alternative medicine place great value upon the clinical experience of the practitioner.

In addition, some proponents of alternative medicine argue that the historical lack of evaluation of conventional medical practices means that it cannot be truly claimed that conventional medicine practitioners relied upon the scientific method for their results. However conventional medical practitioners and scientists would not agree that this means that science should not underpin medical practice.

Proponents of alternative medicine argue that some branches of alternative medicine were viewed as quackery in the past, but are accepted as mainstream medicine now.

Some mainstream doctors and some scientists agree that new research may be revealing evidence that a small number of alternative health treatments might be effective (Michelson et al, 2003; Gonsalkorale et al, 2003; Berga et al, 2003). They are treatments claimed to have resulted from peer-reviewed studies. As such, in a few cases, the boundary lines between alternative and mainstream medicine may change over time. In principle, methods considered alternative at one time may later be adopted by conventional medicine and treatments.

Research methodology and alternative medicine

Experimental evaluation of alternative medicine is often difficult. Some of the problems that arise (Ernst, 2003) are:

  • Double-blind trials are difficult for many alternative medical techniques, which involve hands-on manipulation by trained practitioners that cannot easily be replaced by an equivalent placebo, or which require a holistic approach to treatment that cannot easily be reduced to a single variable.
  • Claimed effects of alternative medical practices are often subtle (requiring large sample sizes) and appear only after long periods of treatment (requiring long studies).
  • Ethical issues arise in conducting double-blind studies where the researchers or patients strongly believe that one treatment is superior to another.
    • An example of dealing with ethical issues is: How can researchers take the religious or philosophical beliefs of the test subjects into consideration when conducting their research so that they will be sure not to offend their underlying beliefs and thus encourage more critical research studies?

These research design difficulties make it difficult for skeptical researchers to do meaningful double-blind research that proponents of alternatives will accept as being valid research. Nevertheless, hundreds of new research articles are being published on the broad area of alternative medicine weekly.

History of alternative medicine

From the 19th century and on into the early 20th century, new ideas about infection and disease were pioneered by Semmelweis and Pasteur, only to meet opposition and ridicule from an establishment which refused to examine the claims of these pioneers. Ignored or ostracized, these pioneers and others like Lister stolidly continued to work and amass evidence showing their theories were true, but it took years before the mainstream adopted them. At the same time, numerous snake oil salesmen sold remedies which had little physical benefit, and in some cases caused serious physical harm. Regulatory agencies like the US's FDA and NIH sought to remedy this contradiction by creating standards to verify the benefits offered by medicines, and a great number of falsifyable drugs and treatments were discarded as a result.
