Chapter 1 Introduction
Clinicians have always performed the role of health care providers, where the family doctor has always been viewed as the logical interface with the community’s health needs. Integrative medicine (IM) is an established paradigm shift in medicine in areas such as the North American continent, India and China. Whereas in other areas of the world it is a developing movement, such as in continental Europe, especially Scandinavia, the Middle East and Australia. 1, 2
In a study of 23 153 German participants, aged 35 to 65 years, from the European Prospective Investigation Into Cancer and Nutrition–Potsdam study, found that adhering to just 4 lifestyle factors — namely, never smoking, having a body mass index less than 30, performing 3.5 hours/week or more of physical activity, and adhering to healthy dietary principles (high intake of fruits, vegetables, and whole-grain bread and low meat consumption) — significantly reduces the risk of developing a chronic disease by up to 78%.5
Holistic health — caring for the whole person
The holistic model is traced back to the Hippocratic school of medicine (circa 400 BC) and the oath of Maimoides (circa the 12th century AD) which have fashioned and defined the unique obligations that clinicians have toward their patients and their medical practices. Disease and illness was viewed as an ‘effect’ from imbalance and explored causes of disease from the environment and natural phenomena such as air, water, and food. Early health practitioners used the term vis medicatrix naturae, meaning the healing power of nature, to describe the body’s ability to heal itself. Furthermore, the Hippocratic oath states: ‘first, do no harm’. It is important despite which style of medicine we use, whether it is a pharmaceutical agent, surgical approach or a natural therapy, that we do no harm to patients.
Holistic medicine also includes the integration of various safe, evidence-based complementary therapies and medicines that may provide a gentler, safer and, in some cases, more empowering approach to health care. Many medical and health practitioners worldwide are integrating various ethical non-pharmaceutical modalities into their clinical practice as part of the holistic approach. These forms of therapies aim to enhance a healthy lifestyle, work with the natural healing process, empower patients to be active participants in their own healing process and nurture the whole person. Where such therapies can be safely used, they include counselling, meditation and relaxation therapies, hypnosis, primary preventative medicine and lifestyle management, acupuncture, nutritional medicine, herbal medicine, environmental medicine, and physical and manipulative medicine. These therapies work in harmony with the natural healing processes of the body. Natural medicines, when used properly, generally are well tolerated and rarely cause side-effects. They generally support the body’s healing mechanisms, rather than take over the body’s processes.6
Integrative medicine
Integrative medicine (IM) refers to the blending of conventional and complementary medicines and therapies with the aim of using the most appropriate of either or both modalities to care for the patient as a whole.7
This closely reflects both the Hippocratic oath and the WHO definition discussed above. However, although some may view IM as synonymous with CAM, this was never so, nor was it ever the case. CAM comprises many therapeutic modalities that are not taught in a conventional medical syllabus, based on the ideas that range from those that are sensible and worth including in mainstream medicine to those that are extremely imprudent and a few that are very perilous. Neither the word alternative nor complementary captures the essence of IM.8 The former suggests a replacement of conventional therapies by others whereas the latter suggests therapies of varying value that may be used as adjuncts.
IM emphasises a number of issues including:9
Complementary and alternative medicine (CAM)
Complementary and alternative medicine, as defined by the National Centre for Complementary and Alternative Medicine (NCCAM), is a group of diverse medical and health care systems, practices, and products that are not presently considered to be part of conventional medicine (see Table 1.1).10
NCCAM classifies natural, complementary and alternative medicines into 5 categories, or domains | |
---|---|
1 Alternative medical systems | Alternative medical systems are built upon complete systems of theory and practice such as homeopathic and naturopathic medicine, Traditional Chinese medicine and Ayurveda. |
2 Mind–body interventions | These interventions include counselling, patient support groups, meditation, prayer, spiritual healing, and therapies that use creative outlets such as art, music, or dance. |
3 Biologically based therapies | These therapies include the use of herbs, foods, vitamins, minerals, dietary supplements. |
4 Manipulative and body-based methods | These methods include chiropractic or osteopathic manipulation, and massage. |
5 Energy therapies | Energy therapies involve the use of energy fields. They are of 2 types: |
As the evidence-base for some CAM increases, medical practitioners have a legal obligation to inform patients of the efficacy of relevant complementary therapies as treatment options, and to simultaneously be aware of the potential for adverse events and interactions that CAMs, such as nutritional and herbal supplements, may have when co-administered with pharmaceutical drugs or when a patient denies good orthodox care for any unproven CAM.11 Knowledge in the efficacy of a complementary medicine or therapy is essential when making clinical decisions for patient care to help weigh against potential risks, such as adverse reactions or delays in useful conventional treatment. This highlights the importance of medical practitioners having at least basic education in the area of CAM to enable them to communicate and inform patients about what therapies are appropriate to the individual. Education on potential risks such as nutrient toxicity, especially with single nutrient use, and any potential interactions with pharmaceuticals is also essential.
Popularity of IM and CAM
Worldwide reports demonstrate that a large proportion of the public are using CAM and its popularity is increasing. For example, in Australia up to 70% of the population are using CAM.12 In the United States, up to 62% of adults use CAM.13 It is therefore vital that health and medical practitioners are well informed about the evidence in these areas.
In many respects, the enthusiasm to use CAM is largely driven by the public. The community has greater access to information and various complementary medicine practitioners and therapies. There are often various reasons why a patient will want to trial CAM. These include philosophical and cultural reasons — wanting a more holistic approach to health care, when there are no longer any other orthodox approaches to assist in their health care, especially if they have suffered any adverse events from orthodox treatments. Generally, patients who use CAM are not rejecting orthodox medicine but are looking for options to improve wellbeing. Unfortunately, medical practitioners underestimate the extent of use of CAM by patients.14, 15 This is of great concern, considering the potential for adverse events such as herb–drug interactions and coordinating the overall management of the patient.
Cultural aspects in determining type of CAM use
The WHO estimates that approximately 60% of medicine that is practiced worldwide is traditional medicine.16 Traditional Chinese medicine (TCM) is practised in many Asian countries, Ayurveda medicine in India, Unani medicine in the Middle-East, Pakistan and India, while Kampo medicine is used in Japan. Biomedicine or conventional medicine is the predominant medicine practised in developed countries and its formation has also been influenced by cultural factors.17
IM strategies and healing
A holistic approach to health care involves giving comprehensive lifestyle advice that is inclusive of physical, social, psychological, emotional and spiritual wellbeing. In this way, we are encouraging and promoting our patients to take personal responsibility and be active participants for their own health. The focus needs to be on wellness, and not specifically on the disease. Positive lifestyle changes and a typical integrative approach to assist healing that can work alongside conventional medicine to improve health outcome or quality of life are listed in Table 1.2.
