| '''Alternative medicine''' is a set of therapies that are considered ''whole systems'' of healthcare that operate outside the realm of mainstream healthcare in the Western world — literally, they consider themselves alternatives to mainstream medicine. '''Complementary medicine''' is comprised of those systems, or parts of systems, that are used in conjunction with the mainstream. Since some techniques may be found both in whole and complementary systems, it is convenient to speak of '''complementary and alternative medicine (CAM)''' as one broad field. Many of these systems predate modern scientific methods and some, particularly the eastern therapies, stem from well before the time of Hippocrates. Some of these practices include [[acupuncture]], [[homeopathy]], [[phytotherapy|herbal medicine]], [[spiritual therapies]], [[chiropractic]], and [[prayer]]. '''Integrative medicine''' deals with the optimal combination of mainstream and complementary medicine.<ref name=ColNur>{{citation
| | The underlying problem is easy to identify: who gets to decide? The U. S. [[Food and Drug Administration]] is supposed to prevent companies or individuals from marketing drugs or food which are not known to be safe, and also to prevent anyone from making claims of efficacy which are not supported by independent studies using accepted scientific methodology. At the national research, the [[National Center for Complementary and Alternative Medicine]] (NCCAM) is part of the U.S. [[National Institutes of Health]]. For a taxonomy of CAM techniques drawn from both NCCAM and the U.K. Parliament committee on CAM, see [[integrative medicine]]. |

| Conventional, biologically-based medicine is not inherently critical of CAM, as some alternatives show as much efficacy as conventional methods, certainly for specific indications. Physicians do express concerns over ''whole systems'' whose patients have not first been evaluated by medically trained physicians for fear that this might delay proper treatment for conditions that are not sufficiently assessed. They also suggest that therapists may either not identify dangerous conditions that are treatable by conventional medicine, such that the patient does not have the information to decide to give [[informed consent]] to alternative treatment alone. Another aspect of that concern is that some conditions can respond to mainstream medical treatment early in the process, but delay of diagnosis could put the patient in a situation where the conventional treatment would no longer be effective.
| | A common distinction is that while there may be varying levels of efficacy data both for complementary and alternative medicine, complementary disciplines are open to collaboration with mainstream medicine and also other complementary practitioners. Alternative practitioners, however, present themselves as a literal "alternative" to conventional medicine. NCCAM also uses the term "whole system" for alternative paradigms that present themselves as "whole" alternatives to conventional medicine. |

| As the term '''integrative medicine''' comes into wider use, its advocates consider it <blockquote>the very best of conventional medicine and cutting-edge diagnosis and treatment, with appropriate complementary therapies. Whenever possible, it favors the use of low-tech, low-cost interventions. All factors that affect health, wellness, and disease are considered, including the psychosocial and spiritual dimensions of a person's life. It brings patients and caregivers into a partnership to achieve the patient's optimal health and healing."<ref name=DukeInt>{{citation
| | But many state agencies also become involved in regulating what is allowed or not allowed. For example, while medical insurance may not recommend or pay for therapeutic massage, chiropractic manipulation, or acupuncture (just for example), many states require practitioners of these arts to be licensed by a state agency intended to guarantee a certain minimum level of competence and training. |

| ==Lack of integration==
| |
| All too often,patients today see both conventional and CAM practitioners, with the patient perhaps not mentioning one type of therapist to the other. In integrative medicine, there is active consultation among the various practitioners and the patient. Integrative medicine also includes [[nursing|nurses]], whose training emphasizes managing chronic diseases (e.g., compliance with monitoring and medicine), encouraging healthy lifestyles, and providing continuity.
| |
|
| |
|
| Integrative medicine reduces some of the concerns that physicians have with patients who self-refer to practitioners of what are indeed complementary techniques, but which might interact with other treatments if all the prescribers are not aware of everything being done. Indeed, one of the challenges of many primary care physicians is simply to find out all the drugs their patients are taking, prescribed by different physician specialists who do not share information.

|
| While some conventional physicians will reject any complementary method for which they do not know the exact mode of action, integrative medicine assumes teams of mainstream and complementary (but not whole system) practitioners. For example, it is quite common for [[pain medicine]] specialists to use complementary methods.

| ==Cost Effectiveness==
| |
| Complementary and alternative therapies are often claimed to be more cost-effective than conventional therapies, but this evalualation is inextricably bound up with disputes about efficacy. Between July, 1999 and June 2005, five complementary therapies – anthroposophical medicine, homeopathy, neural therapy, phytotherapy and traditional Chinese herbal therapy – were included on a trial basis among services covered by the compulsory health insurance scheme in Switzerland. In June 2005, the Swiss interior ministry decided to withdraw these alternative medicines from compulsory heath insurance on grounds of poor cost-effectiveness following a report of their Complementary Medicine Evaluation Programme (PEK). The decision was influenced by pre-publication sight of the study on which a Lancet article critical of homeopathy <ref>(Shang A ''et al.'' (2005) Are the clinical effects of homoeopathy placebo effects? Comparative study of placebo-controlled trials of homoeopathy and allopathy. ''Lancet'' 366:726–32</ref> which was accompanied by an editorial entitled “The end of homeopathy”<ref> Editorial. The end of homeopathy ''Lancet'' 2005; 366: 690 </ref>. In its summary, the PEK report stated: | |
| | |
| <blockquote>”Practitioners of complementary medicine can be distinguished from physicians providing conventional healthcare with regard to the nature, location and technical resources of their practice. The patients they treat tend to be younger, female and better educated. These patients tend to have a favourable attitude towards complementary medicine and to exhibit chronic and more severe forms of disease. Technical diagnostic procedures are performed more rarely, and patients’ wishes are taken into account more frequently in the choice of treatment. On average, the consultation lasts markedly longer than in conventional care. Patients are more satisfied with the care provided in practices offering complementary medicine. Side effects are reported by markedly fewer patients than with conventional care – with the exception of phytotherapy. With complementary medicine, the total annual costs are markedly lower than the average for conventional care. Overall, however, complementary practitioners treat fewer patients, and more frequently younger and female patients. Adjusted for these factors, the total patient- related costs do not differ significantly from those for conventional care. The cost structure is characterized by a greater weighting for consultation costs and a lower weighting for drug costs.” <ref> From the English summary of the Swiss [http://biblio.parlament.ch/e-docs/139404.pdf Complete text of the official Complementary Medicine Evaluation Programme report.] (In German, with summaries in German, French, Italian and English.) </ref></blockquote>

| ==Attitudes of conventional medicine to CAM==
| |
| | |
| An editorial in ''Archives of Internal Medicine'' argues that alternative medicine should not be "condemned out of hand," but that traditional medicine should approach alternative therapy using five principles:
| |
|
| |
| 1. ''Maintain an open-minded attitude about all potentially new therapeutic interventions that include those commonly referred to as alternative.
| |
|
| |
| 2. ''Encourage carefully performed and appropriately controlled studies of these new therapies.
| |
|
| |
| 3. ''Do not ignore or ridicule the potential of the placebo effect to produce marked therapeutic benefit.
| |
|
| |
| 4. ''Do not accept all new therapies as efficacious on first acquaintance. Practitioners of quack medicine continue to abound as in all earlier times. Claims of therapeutic efficacy should be rationally examined and tested.
| |
|
| |
| 5. ''Avoid hubristic and arrogant attitudes toward alternative medical practices because one might be embarrassed by the subsequent demonstrations of their clinical efficacy.''<ref> Alpert JS (1995) The relativity of alternative medicine. ''Arch Intern Med'' 155:2385. </ref>

| The following statements, recommended by the Council on Scientific Affairs, were adopted by the AMA House of Delegates as AMA policy at the 1997 AMA Annual Meeting.<ref>[http://www.ama-assn.org/ama/pub/category/13638.html Alternative medicine] Report to the AMA on the medical/scientific literature on this subject as of June 1997.</ref>

| *"There is little evidence to confirm the safety or efficacy of most alternative therapies. Much of the information currently known about these therapies makes it clear that many have not been shown to be efficacious. Well-designed, stringently controlled research should be done to evaluate the efficacy of alternative therapies.
| |
| *Physicians should routinely inquire about the use of alternative or unconventional therapy by their patients, and educate themselves and their patients about the state of scientific knowledge with regard to alternative therapy that may be used or contemplated.
| |
| *Patients who choose alternative therapies should be educated as to the hazards that might result from postponing or stopping conventional medical treatment.
| |
| *Courses offered by medical schools on alternative medicine should present the scientific view of unconventional theories, treatments, and practice as well as the potential therapeutic utility, safety, and efficacy of these modalities."
