Complementary and Alternative Medicine in Cancer Pain Management a Systematic Review

The widespread use of complementary and culling medicine (CAM) is of major importance to today'due south health care consumers, practitioners, researchers, and policy makers. For instance, look at the following statistics on CAM: 42 percent of people in the Us study that they have used at least one CAM therapy: however, less than xl percent of those using CAM disclosed such use to a physician. In 1997, an estimated xv million adults took prescription medications meantime with herbal remedies or high-dose vitamins, bringing into play the possibility of negative interactions. Full visits to CAM providers exceed total visits to all primary-care physicians. Out-of-pocket costs for CAM are estimated to exceed $27 billion, which shows that CAM is now big business organisation. Hospitals, managed care plans, and conventional practitioners are incorporating CAM therapies into their practices. Medical schools, nursing schools, and schools of pharmacy are education their students near CAM. Information about CAM flows freely in diverse media: newspapers, magazines, books, pamphlets, and the Internet. Friends talk to friends almost remedies for specific problems.

But what is CAM? Who is using CAM, and why are they doing so? Are CAM therapies prophylactic? Are they effective? These are just a few of the questions surrounding the use of CAM by the American public. This chapter provides a framework for thinking about questions related to CAM utilize, explores the definition of CAM, describes a taxonomy for thinking about various CAM modalities, provides an overview of recent events in the history of CAM use in the United States, and briefly describes CAM activities currently nether way at the National Institutes of Health (NIH) and the Agency for Healthcare Research and Quality (AHRQ).

This chapter begins by setting the context for the committee'southward consideration of CAM on the basis of a more general model of wellness care decision making.

CONTEXT

Questions about CAM utilise arise at a time when providers of conventional medical care are being challenged as never before to examine the effectiveness and efficiency of health care in the United States. The Institute of Medicine's (IOM'due south) Crossing the Quality Chasm (IOM, 2001) provides ample testify for the underuse of effective care, the overuse of marginally effective or ineffective care, and the misuse of care, including preventable errors, in its delivery. Widespread variation in rates of surgery and other interventions for common conditions among seemingly like populations in different geographic regions raises concern nearly how doctors and patients make decisions.

The Crossing the Quality Chasm written report concludes that bitty, incremental alter will exist insufficient to attain achievable levels of quality improvement in American wellness care. Fundamental redesign will be required, and the report offers ten rules for redesign. Taken together, these suggestions advocate a systems-minded approach to making health care more than knowledge based and patient centered.

This study is about CAM, not about the quality of conventional medicine or the fashion in which it is delivered. All the same, as will be seen, central to the definition of CAM is that its elective elements are "other than" conventional medicine. Therefore, an appreciation of both the strengths and the limitations of conventional medicine, specially as perceived by CAM users in the U.s.a., is necessary context for development of conceptual models to guide public and private decision making about CAM research and practices.

The main conceptual model that the committee used to frame this written report begins with the question, What exercise patients and health professionals need to know to make skillful decisions about the apply of health care interventions, including CAM? Corollary questions for policy makers relate to the enquiry necessary to support decisions as well as policies and resources to ensure the quality and efficiency of services as well as equitable admission. The more general nature of the question and its corollaries, addressing wellness intendance interventions rather than CAM interventions alone, reflects the committee'southward view that the decision-making needs of stakeholders in the American wellness intendance economic system are equivalent for conventional and CAM wellness care services.

For the patient with symptoms or signs that diminish the quality of life or raise concerns almost the length of life, answers to simple but compelling questions are necessary for decision making. What is incorrect? What will happen if I exercise nada: will things get better, worse, or stay the aforementioned? What are my handling options, and what are the benefits and harms? What volition the experience of treatment feel like? How likely am I to benefit, by how much, and for how long? How probable am I to exist harmed, in what way, and for how long? Those who are well and want to stay that way by preventing preventable illness ask like questions. The all-time answers to these questions come from a professional person knowledge base that may be more or less supported by conclusive prove relevant to the circumstances of the particular patient at hand. When such evidence does be and is effectively marshaled and communicated, the decisions and resulting care attain the goal of being "noesis based."

Adept decisions depend on more than than professional noesis about treatment options and probabilities of outcomes. Different patients may be more or less bothered by the same symptoms. They may react differently to the experience of treatment itself and anticipate different reactions to the benefits or the harms, or both. Furthermore, no thing how good the bear witness, there is always some dubiety about outcomes for the private patient. Risks that are acceptable to some may exist unacceptable to others. Benefits or harms may be more or less likely to occur early on or late, and patients' willingness to make trade-offs between the two is variably influenced past the timing of the good versus the bad. When particular patients' attitudes and preferences are elicited and respected, decisions most treatment and prevention and the resulting intendance achieve the goal of existence "patient centered."

It has been argued that there is much unwarranted variation in medical practice because of failures related to direction of the professional person knowledge base. In some cases the necessary research has not been done. In others, it is inaccessible to clinicians at the fourth dimension that decisions are made. Evidence is also misinterpreted or inappropriately practical to a patient who is different from those whose experience provided the basis for the evidence. Furthermore, different clinicians have different understandings of how a profession knows what it knows and how the knowledge base is advanced. These epistemological differences may be even greater among users of conventional and CAM interventions.

Among clinicians who practice conventional medicine, at that place has been a marked shift over past decades from a reliance on professional feel to a greater accent on more rigorous quantitative evidence derived from randomized trials and systematic reviews of multiple trials. These more than rigorous approaches have more recently been used in investigations of CAM. However, among the heterogeneous interventions that comprise CAM, particularly those that depend on variable practitioner approaches and the customization of interventions to private patients, at that place are pregnant obstacles to use of the methods that take gained potency in testing and advancing the noesis base of operations for conventional medical practitioners.

Despite the axiomatic differences betwixt conventional clinical practice and CAM, perchance the most promising way to observe common ground is to ask the question, What kind of knowledge do people need to make practiced health intendance decisions, and how can that noesis be continuously tested and improved? This question provides the framework for because the appropriate clinical and policy responses to the widespread use of CAM past the American public.

Furthermore, this framework is based on a set up of upstanding commitments that informed the work of the committee as it proceeded with its task. These commitments are explored in particular in Chapter vi:

a social commitment to public welfare,
a commitment to protect patients and the public,
respect for patient autonomy,
a recognition of medical pluralism, and
public accountability.

One of the showtime questions that the committee considered was, What is CAM? The following department explores this issue.

DEFINITION OF CAM

One of the difficulties in whatever study of CAM is trying to determine what is included in the definition of CAM. Does CAM include vitamin use, nutrition and diets, behavioral medicine, exercise and other treatments that accept been integrated into conventional medical systems? Should CAM include prayer, shamanism, or other therapies that may not be considered health intendance practices? Every bit discussed farther in Chapter half-dozen, the reasons for defining modalities every bit "CAM therapies" are non only scientific but also "political, social, [and] conceptual" (Jonas, 2002). In the United States, some of the most oftentimes used and well-known therapies that are recognized as CAM are relaxation techniques, herbs, chiropractic, and massage therapy (Eisenberg et al., 1998). Chiropractic, acupuncture, and massage therapy are licensed in almost states. Naturopathy and homeopathy are licensed in fewer states. Numerous other therapies and modalities are considered unlicensed practices and at present few or no formal regulations apply to these therapies and modalities. The New York State Office of Regulatory Reform and CAM has identified more than 100 therapies, practices, and systems that could be considered CAM (see Appendix A for a list of therapies).

A lack of consistency in the definition of what is included in CAM is institute throughout the literature. The National Eye for Complementary and Culling Medicine (NCCAM) of NIH defines CAM every bit "a group of diverse medical and wellness care systems, practices, and products that are non shortly considered to be part of conventional medicine" (NCCAM, 2002). However, many would argue that a therapy does non end to be a CAM therapy considering it has been proven to exist safe and effective and is used in conventional practice. "Merely considering an herbal remedy comes to be used by physicians does not hateful that herbalists cease to practise, or that the practise of the one becomes similar that of the other" (Hufford, 2002:29).

Descriptive definitions of CAM include one by Ernst et al. (1995), who write that CAM is a "diagnosis, treatment and/or prevention which complements mainstream medicine by contributing to a mutual whole, satisfying a demand not met by orthodox, or diversifying the conceptual framework of medicine." Gevitz (1988) proposes that CAM includes "practices that are non accustomed as correct, proper, or advisable or are non in conformity with the beliefs or standards of the dominant group of medical practitioners in a society." In 1993, Eisenberg et al. divers CAM as "interventions neither taught widely in medical schools nor generally available in hospitals."

Kopelman (2002) argues that descriptive definitions such as those offered past Ernst et al. and Gevitz do not fairly reply the question, What is CAM? Definitions that place CAM outside the politically ascendant health intendance organization neglect "to offering a standard for differentiating conventional interventions and CAM other than by appealing to what is or is non intrinsic to the practices of the dominant culture. This assumes there is a reliable and useful way to count cultures or subcultures and sort them into those that are dominant and those that are non" (Kopelman, 2002). Other descriptive definitions fail because weather condition change, and therefore, descriptions of the conditions are no longer accurate. For example, look at the definition of Eisenberg and colleagues (1993), which states that CAM comprises inteventions that are neither taught widely in medical schools nor generally bachelor in hospitals; however, more than than one-half of all U.S. medical schools provide education almost CAM, wellness care institutions are offer CAM services, and the numbers of insurers offering reimbursement for CAM therapies is growing (see Chapters 7 and eight).

According to Kopelman, normative definitions (e.g., untested or unscientific) also fail to distinguish CAM from conventional medicine. For example, Angell and Kassier (1998) write "in that location is only medicine that has been adequately tested and medicine that has not." Even so such a definition does non distinguish between conventional medicine and CAM considering many conventional treatments have not been supported past rigorous testing. For case, a review of 160 Cochrane systematic reviews of the effectiveness of conventional biomedical procedures institute that 20 percentage showed no result, whereas insufficient evidence was available for another 21 pct (Ezzo et al., 2001). Furthermore, "some CAM manufacturers adopt college standards than are currently required in the The states and rigorously test their CAM products" (Kopelman, 2002).

Stipulative definitions (i.east., lists of therapies) are not successful in distinguishing CAM from conventional therapies, Kopelman argues, because they are non consequent from source to source and they provide no justification for the exclusion of therapies that are non included.

Given the lack of a consistent definition of CAM, some have tried to bring clarity to the situation by proposing nomenclature systems that can be used to organize the field. One of the most widely used nomenclature structures, developed by NCCAM (2000), divides CAM modalities into 5 categories:

Alternative medical systems,
Heed-body interventions,
Biologically based treatments,
Manipulative and trunk-based methods, and
Energy therapies.

As the name implies, culling medical systems is a category that extends across a single modality, and refers to an entire system of theory and practice that adult separately from conventional medicine. Examples of these systems include traditional Chinese medicine, ayurvedic medicine, homeopathy, and naturopathy.

The 2d category in the NCCAM classification scheme is mind-body interventions, which include practices that are based on the human mind, but that accept an issue on the man torso and physical health, such every bit meditation, prayer, and mental healing.

The third category, biologically based therapies, includes specialized diets, herbal products, and other natural products such as minerals, hormones, and biologicals. Specialized diets include those proposed by Drs. Atkins and Ornish, as well as the broader field of functional foods that may reduce the risk of disease or promote wellness. A few of the well-known herbals for which there is evidence of effectiveness include St. John'due south wort for the treatment of mild to moderate depression and Ginkgo biloba for the treatment of balmy cerebral harm. An example of a nonherbal natural product is fish oil for the treatment of cardiovascular weather condition.

The fourth category, manipulative and trunk-based methods, includes therapies that involve movement or manipulation of the trunk. Chiropractic is the best known in this category, and chiropractors are licensed to practice in every U.S. state. A defining characteristic of chiropractic treatment is spinal manipulation, also known as spinal adjustment, to correct spinal articulation abnormalities (Meeker and Haldeman, 2002). Massage therapy is another example of a torso-based therapy.

The final category described past NCCAM is energy therapies which include the manipulation and application of energy fields to the body. In add-on to electromagnetic fields outside of the body, it is hypothesized that free energy fields exist inside the body. The existence of these biofields has non been experimentally proven; however, a number of therapies include them, such as qi gong, Reiki, and therapeutic touch.

A dissimilar approach to classifying CAM modalities is a descriptive taxonomy that groups therapies co-ordinate to their philosophical and theoretical identities (Kaptchuk and Eisenberg, 2001). Practices are divided into two groups. The get-go group appeals to the full general public and has become popularly known as CAM. This group includes professionalized or distinct medical systems (eastward.thousand., chiropratic, acupuncture, homeopathy), popular health reform (e.g., dietary supplement use and specialized diets), New Age healing (e.g., qi gong, Reiki, magnets), psychological interventions, and nonnormative scientific enterprises (conventional therapies used in unconventional ways or anarchistic therapies used by conventionally trained medical or scientific professionals). The second group includes practices that are more relevant to specific populations, such as ethnic or religious groups (due east.thou., Native American traditional medicine, Puerto Rican spiritis, folk medicine, and religious healing).

This word of definitions shows that no clear and consequent definition of CAM exists, nor is there a recognized taxonomy to organize the field, although the ane proposed past NCCAM is normally used. Given the committee'due south charge and focus, for the purposes of this report, the commission has chosen to employ equally its working definition of CAM a modification of the definition proposed by the Panel on Definition and Description at a 1995 NIH enquiry methodology briefing (Defining and describing complementary and culling medicine, 1997). This modified definition states that

Complementary and alternative medicine (CAM) is a broad domain of resources that encompasses health systems, modalities, and practices and their accompanying theories and beliefs, other than those intrinsic to the dominant health system of a particular society or civilization in a given historical period. CAM includes such resource perceived by their users as associated with positive health outcomes. Boundaries within CAM and between the CAM domain and the domain of the dominant organisation are not always sharp or fixed.

The committee chose this definition for several reasons. First, this broad definition reflects the scope and essence of CAM every bit used by the American public. 2nd, information technology avoids excluding common practices from the enquiry calendar. The result of such a wide definition means that all statements and recommendations made in this report volition not apply as to all CAM modalities and there may even be some CAM modalities for which particular statements do not use at all. The third reason for choosing to ascertain CAM as stated above is that information technology is patient centered and includes practices that people perceive to have wellness benefits. Fourth, it encompasses the potential for change. That is, this definition allows a therapy to be accustomed as standard practice when there is evidence of effectiveness but all the same allows the therapy to remain a part of CAM. Furthermore, the called definition recognizes that the definition of "conventional" medicine volition vary from time to fourth dimension and from state to land, it does not presume that proven practices will be adopted, and information technology allows CAM to be evaluated over time.

The next section of this affiliate is devoted to describing milestones in the recent history of CAM in the United states.

Contempo MILESTONES IN THE HISTORY OF CAM

In 1992 the U.S. Congress established the Office of Unconventional Therapies, afterwards changed to the Office of Alternative Medicine (OAM), to explore "unconventional medical practices." Ii one thousand thousand dollars was appropriated, and OAM began to develop a baseline of information on CAM use in the United States. Culling Medicine: Expanding Medical Horizons was released in 1995 (Workshop on Alternative Medicine, 1995) and summarized the results of ii workshops on CAM convened past OAM. The report (frequently referred to as the "Chantilly Study" because the workshops were held in Chantilly, Virginia, in 1992) examined six fields of alternative medicine and addressed problems such equally inquiry infrastructure, research databases, and research methodologies. Many of the recommendations made addressed research needs and opportunities. The written report was pregnant because it was the result of the showtime NIH-sanctioned meetings held to discuss the field of CAM equally a whole.

Responding to public and industry input, Congress passed the Dietary Supplement Health and Education Act (DSHEA) in 1994. DSHEA legally established the term "dietary supplement" and decreed that supplements were to be regulated similar to foods. This stardom exempted manufacturers from conducting premarketing safety and efficacy testing and eliminated the Food and Drug Administrations's (FDA'southward) premarketing regulatory authority. In 1995, NIH funded the Research Centers Program to provide a nationwide focus for interdisciplinary CAM enquiry in academic institutions. Also in 1995, post-obit a 1994 NIH and FDA workshop on acupuncture, FDA declassified acupuncture needles as an experimental product. In 1996 the Public Information Clearinghouse on CAM was established and NIH sponsored the Consensus Conference on Acupuncture, which provided testify of the effectiveness of acupuncture for some weather (e.one thousand., dental pain and nausea).

The first big, multicenter trial of a CAM therapy was cofunded in 1997 past OAM, the National Institute on Mental Wellness, and the NIH Function of Dietary Supplements. The trial tested the upshot of Hypericum (St. John's wort) for low.

Past 1998 the use of CAM was widely discussed and hotly debated. A New England Periodical of Medicine editorial (Angell and Kassirer, 1998) argued that "Information technology's time for the scientific community to stop giving CAM a free ride. At that place tin non be two kinds of medicine—conventional and alternative. There is only medicine that has been fairly tested and medicine that has non, medicine that works and medicine that may or may not work." An editorial in the Journal of the American Medical Association contended that "There is no Alternative Medicine. There is only scientifically proven, evidence-based medicine supported past solid data or unproven medicine, for which scientific evidence is defective" (Fontanarosa and Lundberg, 1998). The American Medical Clan devoted infinite to the topic of CAM in its theme journals and published a total of 80 articles and the results of 18 randomized trials. Included were editorials, descriptive articles, systematic reviews, and results of randomized controlled trials. For the first time, CAM was addressed every bit a complex result and journal editors were willing to subject these articles to the same criteria and editorial review equally manufactures addressing topics in conventional medicine.

Meanwhile, Congress, having increased the OAM budget from the original $2 million to $19.five million, elevated OAM to the level of a national eye named NCCAM in 1998, awarded it $48.9 million for fiscal year (FY) 1999, and required that NCCAM appoint CAM practitioners as members of its Advisory Council. In 1999, the Cancer Advisory Console for CAM was established for the purpose of assessing clinical data related to CAM treatment of cancer and the first Dietary Supplements Enquiry Heart was funded jointly past NCCAM and the NIH Office of Dietary Supplements. NIH funded nine Centers for Inquiry of Complementary and Alternative Medicine to conduct interdisciplinary enquiry and training. Three multicenter research studies were funded: ane on Ginkgo biloba for the treatment of dementia (cofunded past NCCAM and the National Institute on Aging), one on glucosamine and chondroitin sulfate for the treatment of knee osteoarthritis (cofunded by NCCAM and the National Institute of Arthritis and Musculoskeletal and Peel Diseases), and one on acupuncture for osteoarthritis of the knee (funded past NCCAM). Also in 1999 large pharmaceutical companies entered the CAM market with herbal product lines and other dietary supplements.

Several major events occurred in 2000 and 2001. In March 2000, President Clinton created the White Firm Commission on Complementary and Alternative Medicine Policy. The purpose of the commission was to "study and report on public policy problems in the quickly expanding field of complementary and alternative medicine." Furthermore, the committee was asked to report on "legislative and administrative recommendations to assure that public policy maximizes the benefits to Americans of appropriate use of complementary and alternative medicine" (Executive Order 13147, 2000). The commission's report provided recommendations most research on CAM, education and training in CAM, CAM information broadcasting, commitment of CAM practices, coverage and reimbursement for CAM services, the potential function of CAM in wellness and wellness promotion, and the demand for coordination of CAM-related efforts (WHCCAMP, 2002).

The Federation of State Medical Boards began work on CAM guidelines for physicians in 2000. The initiative was focused on "encouraging the medical community to adopt consequent standards, ensuring the public health and prophylactic by facilitating the proper and effective apply of both conventional and CAM treatments, while educating physicians on the adequate safeguards needed to clinch these services are provided within the premises of adequate professional practice" (FSMB, 2002). The federation's House of Delegates approved the guidelines in April 2002.

The Consortium of Academic Health Centers for Integrative Medicine was launched in 2000 and past 2003 it had 22 member medical schools (come across Appendix B for a list of fellow member centers). To become a fellow member, either the dean or chancellor is required to commit to developing programs in research, education, and clinical delivery of CAM and the school must demonstrate an organized and robust programme in 2 of those three areas. The mission of the consortium is "to assistance transform medicine and healthcare through rigorous scientific studies, new models of clinical care, and innovative educational programs that integrate biomedicine, the complexity of homo beings, the intrinsic nature of healing and the rich variety of therapeutic systems" (Consortium of Bookish Health Centers for Integrative Medicine, 2004).

Skeptics of CAM had long contended that the just do good derived from CAM therapies was due to a placebo outcome, not "real" effects. In November 2000 NIH hosted a workshop, The Science of the Placebo: Toward an Interdisciplinary Inquiry Agenda, thereby helping to place placebo in the category of a "real" event. The August 2001 issue of Science published an article on bones scientific discipline mechanisms of placebo (de la Fuente-Fernandez et al., 2001). These 2 events triggered expanded interest among the neuroscience community in the study of the bear on of nonspecific effects (e.chiliad., expectation, context, belief) on clinical outcomes. Placebo was no longer something to be discarded or dismissed but, rather, something to be studied.

Besides in 2001, NCCAM and the National Library of Medicine developed CAM on PubMed, a gratis, web-based access to journal citations directly related to CAM. At nowadays, almost xl,000 citations on CAM tin be plant on the PubMed website. Additionally, clinically significant adverse drug-herb interactions were documented in case studies (Fugh-Berman, 2000), and St. John's wort was shown to reduce the level of indinavir, a protease inhibitor taken by AIDS patients, in plasma (Piscitelli et al., 2000).

In 2002, NCCAM launched its Intramural Program to explore CAM treatment strategies for patients at the NIH Clinical Middle, the world's largest facility dedicated to patient-oriented inquiry. Also in that yr, the U.South. Department of Veterans Affairs agreed to provide reimbursement for chiropractic intendance, the Annals of Internal Medicine began a special series on CAM (17 publications), and Science Xpress published an article on positron emission spectrometry, imaging of the placebo response versus the response to opiod analgesics, thereby signalling continued involvement in the application of modern technology to the mechanistic study of placebo-related phenomena.

NCCAM, whose budget had grown to $104.6 one thousand thousand in 2002, funded ten international planning grants, and across NIH more than 200 research projects on CAM were ongoing. As well in that yr, IOM established the Commission on the Use of Complementary and Culling Medicine by the American Public. In 2003, the first two Centers of Excellence for Inquiry on CAM were funded to increase scientific rigor in inquiry on CAM. Past 2004 the NCCAM upkeep was $117.eight million.

The following section explores in greater detail, the kinds of research and training efforts undertaken by NIH and the AHRQ

CAM ACTIVITIES AT NIH AND AHRQ

National Centre for Complementary and Alternative Medicine

Xx institutes and centers within NIH back up ongoing CAM-related enquiry, with NCCAM beingness the principal centre for such inquiry. Co-ordinate to the legislation creating NCCAM (P.Fifty. 105-277), NCCAM'south mandate is the "conduct and support of basic and applied research (intramural and extramural), research training, and [to] disseminate health data and other programs with respect to identifying, investigating, and validating CAM treatments, diagnostic and prevention modalities, disciplines and systems." To accomplish its mandate, NCCAM focuses on four primary areas: research, research training and career development, outreach, and integration.

To guide its inquiry efforts, NCCAM develops plan priorities through a semiannual formal review procedure. At present, its three priority areas are to elucidate the mechanisms of action and bear small, well-developed Phase I and II studies; build infrastructure to support research at CAM institutions; and encourage collaboration between institutions that provide conventional medical therapies and those that provide CAM therapies (http://nccam.nih.gov/enquiry/priorities/alphabetize.htm).

The development of research centers is the main method used to pursue inquiry. NCCAM's CAM-related enquiry centers can be placed into several categories: Dietary Supplement Research, Developmental Centers that partner institutions where CAM is proficient and those where conventional medicine is adept, Centers of Excellence, Centers for CAM Inquiry, and Exploratory Program Grants for Frontier Medicine Research. The establishment of international centers for CAM research is as well an initiative in development. Unlike the other centers at NIH, which invest about two-thirds of their enquiry funding in bones research, NCCAM places the largest proportion of its resources in clinical research; the ratio of funding for clinical inquiry to funding for basic research was ii.five:1 in FY 2003 (NCCAM, 2004).

An impressive number of patients are participating in NCCAM-supported clinical trials (10,708 participants in 2002), more than half of whom are in Phase 3 clinical trials. Inquiry on prevention (e.chiliad., research directed to such areas as dementia, prostate cancer, and myocardial infarction) is some other emphasis of NCCAM, as are studies on women'southward health (due east.thousand., research examining the furnishings of plant-based estrogens), research on reducing or eliminating health disparities, and age-related wellness research.

In addition to increasing support for research projection grants and enquiry centers, since FY 1999 NCCAM has dramatically increased the funding devoted to training, career, and curriculum awards (Straus, 2003). Such funds are consequent with NCCAM's goal of increasing the number of skilled CAM researchers past making awards for CAM-related research available to pre- and postdoctoral students, CAM practitioners, conventional medical researchers and practitioners, and members of underrepresented populations in scientific enquiry (http://nccam.nih.gov/training/overview.htm).

NCCAM also participates in a variety of outreach efforts. It maintains several outlets for both the public and the research customs. The NCCAM website (http://nccam.nih.gov/) provides detailed descriptions of its ongoing activities as well as fact sheets nigh CAM, information on factors related to decision making about treatments, cost and payment questions, and safety alerts and advisories. NCCAM also publishes a quarterly newsletter containing updates on new and ongoing activities of the center. NCCAM too uses lectures, town meetings, and exhibits at scientific meetings as opportunities to increase people's sensation of CAM and the center.

In addition, NCCAM has established a clearinghouse, attainable by Internet and telephone in both English language and Castilian, for people seeking information about CAM. The clearinghouse does non provide medical advice but does disseminate scientifically based data on CAM. Two other activities that help with outreach are publications in peer-reviewed scientific journals, the number of which is increasing, and the evolution of the CAM on PubMed subsection of the National Library of Medicine's MEDLINE database.

I of NCCAM's stated goals is to "integrate scientifically proven CAM practices into conventional medicine" (http://nccam.nih.gov/well-nigh/aboutnccam/index.htm). Integration is an obvious extension of NCCAM's investments in research, research preparation, and expanding outreach. NCCAM hopes to aid integration past publishing research results, investigating means in which evidence-based CAM practices can be integrated into conventional medical practice, and supporting programs that develop models for the incorporation of CAM into medical, dental, and nursing school curricula.

NCCAM is in the process of developing its 2d v-year strategic plan, which will be released in January 2005. NCCAM plans to go on focusing on research, research training, outreach, and integration and intends for its 2nd strategic plan to provide greater specificity and prioritization within these areas.

Ane tin can come across from this discussion that NCCAM has an impressive and well-organized series of activities designed to advance the state of cognition well-nigh CAM therapies and their use. NCCAM's mandated focus is on CAM, however other centers and institutes inside the NIH besides have impressive portfolios evaluating CAM therapies. NCCAM established the xl-member Trans-Agency CAM Coordinating Committee in 1999 to foster collaboration across these various institutes and other federal agencies involved with research on CAM. The post-obit department describes some of the activities of NIH institutes and centers.

NIH Institutes and Centers

As seen in Table 1-1, institutes and centers other than NCCAM collectively spend millions of dollars on CAM-related activities. The NIH institutes and centers comport research in partnership with each other and independently, facilitating a broad scope of action in both clinical and basic research. At that place is ongoing enquiry on the condom and efficacy of CAM practices for disease treatment and prevention; mechanisms of therapies including dietary supplements such equally soy isoflavones and acupuncture; placebo effects; the part of spirituality in health; equally well as animal studies of alternative therapies for Parkinson'southward disease. Table 1-1 displays the level of funding for CAM enquiry by heart or found for the past few years.

CAM Funding by NIH Institute or Eye.

Function of Cancer Complementary and Culling Medicine

The Part of Cancer Complementary and Alternative Medicine (OCCAM) within the National Cancer Establish (NCI) develops and coordinates CAM activities related to cancer. OCCAM was established in 1998. Program efforts are divided amid three areas: Research Development and Support Program, Do Assessment Program, and Communications Program.

The Research Development and Support Program funds enquiry on CAM for the prevention, diagnosis, and treatment of cancer; CAM for cancer-related symptoms; and CAM modalities that can address the side furnishings of conventional treatment. Examples of contempo activities include a methodology working group on research on cancer symptom direction past the employ of CAM, the provision of competitive supplementary funds for NCI-designated cancer centers, and a workshop on how to write a grant to receive funding for research on cancer-related CAM modalities.

The Practice Assessment Program has 2 primary objectives: (1) to evaluate potential therapies and appraise whether future research is warranted and (2) to build a dialogue betwixt health practitioners and researchers about CAM and cancer issues. The Do Assessment supports the Best Case Serial Program for groups of cancer patients treated with CAM therapies. Examples of best instance series that have been completed are the Kelly-Gonzalez Regimen for pancreatic cancer and insulin potentiation therapy investigated by Steven Ayre.

Lastly, the Communications Plan develops and disseminates information nearly NCI activities and obtains feedback about interests and obstacles in CAM-related inquiry on cancer. Like NCCAM, OCCAM sponsors conferences, lectures, and skillful panels to increase the quality and awareness of ongoing CAM-related inquiry on cancer.

Office of Dietary Supplements

The Office of Dietary Supplements (ODS) is part of the Function of NIH Managing director and was established in 1995 in response to a congressional mandate (DSHEA, 1994). Its mission is to "strengthen knowledge and understanding of dietary supplements by evaluating scientific data, stimulating and supporting inquiry, disseminating enquiry results, and educating the public to foster an enhanced quality of life and health for the U.Southward. population."

ODS, unlike the NIH institutes and centers, cannot directly fund investigator-initiated research. However, information technology partners with the NIH institutes and centers and government and individual agencies to achieve its mission by supporting research, sponsoring conferences, and disseminating information. In January 2004, ODS released its 2004-2009 Strategic Programme, its second such plan, which independent five overarching goals related to enquiry, information communication, and educational activity. Although these goals have been adopted for the second strategic programme, greater emphasis volition be placed on the use of emerging technologies, cross-disciplinary studies, training and education of investigators, translation of research, and institution of a procedure for regular evaluation of ODS programs and activities.

In the final 5 years, ODS has initiated many efforts to ameliorate the quality of research on dietary supplements. For case, ODS established a program to heighten analytical methodologies and develop standard reference preparations of dietary supplements and also created 2 databases that are accessible to everyone: the Computer Access to Research on Dietary Supplements database (CARDS) and the International Bibliographic Information on Dietary Supplements (IBIDS). CARDS contains data on federally funded dietary supplement research and is continually updated. IBIDS provides access to bibliographic citations and abstracts from published, international, scientific literature on dietary supplements. An additional resource for the enquiry community and full general public are show-based review reports commissioned through a partnership between ODS and NCCAM from AHRQ Evidence-Based Practise Centers.

ODS, in various partnerships with NCCAM, the National Constitute for Ecology Health Sciences, the Office of Inquiry on Women's Health, and the National Institute of General Medical Sciences, funds 6 Centers for Dietary Supplement Enquiry. The centers emphasize botanicals and aim to identify and characterize these compounds, appraise their bioavailabilities and activities, explore their mechanisms of action, conduct preclinical and clinical evaluations, establish training and career evolution, and help select the botanicals to be tested in clinical trials.

Agency for Healthcare Inquiry and Quality

The AHRQ, which is function of the U.S. Department of Health and Human Services, is authorized to sponsor, comport, and disseminate research to improve the quality and effectiveness of health intendance. AHRQ administers Evidence-Based Practice Centers (EPCs), which have produced evidence-based reports requested by other federal agencies on the effectiveness and safe of a express number of dietary supplements. The reports of the EPCs are based on a systematic analysis of the relevant scientific data and are designed to differentiate the types and strengths of a comprehensive body of bear witness.

Nominations for clinical topics to exist reviewed past an EPC are solicited through notices in the Federal Register. The clinical topics must encounter specific selection criteria including a high incidence; significance for the needs of Medicare, Medicaid, or other federal health programs; loftier toll; controversy about their effectiveness; and the availability of scientific data. On the basis of this process, reports on six dietary supplements¹ have been reviewed as of October 2003. In addition to the prove-based practise reports, AHRQ also funds investigator-initiated research and supports a small number of grants for CAM-related research.

The Constitute of Medicine Written report of CAM

The previous pages have described the progress that has been made in evaluating and understanding CAM. Nonetheless, numerous challenges remain to exist confronted as individuals seek to make decisions virtually the safety, effectiveness, and use of diverse CAM therapies and modalities. In September 2002, NCCAM, 15 other NIH centers and institutes, and AHRQ deputed the IOM to conduct a study on the apply of CAM by the American public. Specifically, the study was to:

Depict the use of CAM therapies past the American public and provide a comprehensive overview, to the extent that information are available, of the therapies in widespread utilise, the populations that use them, and what is known virtually how they are provided.
Identify major scientific, policy, and practice issues related to CAM inquiry and to the translation of validated therapies into conventional medical practice.
Develop conceptual models or frameworks to guide public- and private-sector decision making equally research and practice communities confront the challenges of conducting research on CAM, translating research findings into do, and addressing the distinct policy and practice barriers inherent in that translation.

Guidance was specifically sought on the following matters:

Study the methodological difficulties in the behave of rigorous research on CAM therapies and how these relate to issues in regulation and do, with exploration of options to address the identified difficulties.
The shortage of highly skilled practitioners who are able to participate in scientific research that meets NIH guidelines and who have admission to the institutions where such research is conducted.
The shortage of receptive, integrated research environments and the barriers to developing multidisciplinary teams that include CAM and conventional medical practitioners.
The availability of standardized and well-characterized materials and practices to be studied and incorporated, when appropriate, into practice.
Existing decision-making models used to decide whether or not to incorporate new therapies and practices into conventional medicine, including testify thresholds.
Applicability of these decision-making models to CAM therapies and practices; that is, do they class good precedents for decisions relating to regulation, accreditation, or integration of CAM therapies?
Identification and analysis of successful approaches to the incorporation of CAM into wellness professions education.
Bear upon of current regulation and legislation on CAM research and integration.

IOM convened the Committee on the Use of Complementary and Culling Medicine (CAM) by the American Public. Betwixt February 2003 and May 2004 the committee met seven times and held five data-gathering workshops, during which testimony was solicited from any individual wishing to provide input to the committee. Over the course of this study the committee met and talked with representatives of various federal agencies, the CAM and conventional medicine communities, researchers, practitioners, educators, and patients. A liaison panel was convened with representatives both from CAM practise communities and from the conventional medicine customs (Appendix D). The liaison panel met with the commission 3 times and provided critical input regarding many important issues including major challenges, methodological bug (e.1000., outcome concepts and measures), and factors facilitating or inhibiting communication and cooperation across disciplines.

Collectively, the commission read, summarized, and analyzed manufactures and other information on CAM therapies, evaluation of evidence, CAM-related decision making, pedagogy on CAM, and much more. The committee commissioned a paper on methodological issues, which provided the information from which Affiliate 4 was adult. The work of the committee has been challenging all the same rewarding. The results of that work are contained in this written report.

REPORT CONTENTS

This written report identifies the major scientific, policy, and practice issues related to CAM. It explores what is known about the apply of CAM, the methods and approaches used for CAM-related inquiry, and how this knowledge is being translated into practice. Finally, the written report provides recommendations to research and do communities as they make decisions and confront the challenges of conducting inquiry on CAM, translate the research findings into practice, and address the distinct policy and do barriers inherent in that translation.

This chapter has provided the context within which this report was developed, the definition and description of CAM, and a brief history and the nowadays view of CAM-related activities under mode at NIH and AHRQ. Affiliate ii describes what is known virtually the prevalence, cost, and patterns of use of CAM therapies and identifies the areas in which more data is needed. A discussion of the approaches to the evaluation of evidence of treatment effectiveness is presented in Chapter 3. Affiliate 4 examines the need for innovative designs in enquiry on CAM. Chapter v explores the existing evidence of the effectiveness for CAM and the gaps in that testify and describes a inquiry framework for utilise in filling the gaps that accept been identified. Chapter vi presents an ethical framework for CAM research, policy, and practice. Chapter 7 reviews the growing integration of CAM and explores why such integration is occurring, and Affiliate eight discusses the pedagogy of both conventional practitioners and CAM practitioners. Chapter 9 focuses on dietary supplements, and Affiliate x presents the decision of the study.

For the body of the report, the committee reviewed a broad cantankerous section of studies on use of CAM in clinical populations that were published in peer-reviewed journals. The list of studies was generated by a PubMed search covering the past eight years plus all reviews of studies on CAM use for particular health complaints and special populations. The committee did non seek to quantify such results as studies were carried out in different clinical settings using different procedures for data drove. CAM use in such settings was cited every bit mutual if such appeared to be the case or was cited equally illustrative every bit noted in the text. Table 2-1 and much of the content for Chapter 2 relies on an exhaustive review of those epidemiological studies of CAM use by the U.S. public which involved random, nationally representative samples that were published in the peer-reviewed medical literature. Apart from those studies cited in Tabular array ii-1, nosotros are not aware of additional publications which meet these straightforward criteria.

For report comments in the qualitative realm (e.g., reasons why different types of people use CAM—Table 2-2) and those referring to private populations (i.e., CAM utilize among population subgroups), publications were generated by (1) a PubMed search, (2) a search of major wellness social scientific discipline journals roofing the fields of anthropology, sociology, psychology and geography, and (3) a library search of books and book chapters on CAM written by those belongings advanced academic degrees and having academic positions in reputable U.S., Canadian, Australian, and British universities. Data on the range of motivations for using CAM was qualitative, and the committee made no attempt to quantify results. Data on the lack of studies on compliance/adherence with CAM was based on a PubMed search that went back 12 years.
