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

Integrative medicine is recognised as the practice of medicine in a way that relates to complete patient care. IM includes practices currently beyond the scope of conventional medical teachings. However, it neither rejects conventional therapies nor uncritically accepts alternative/complementary ones. It implicitly emphasises principles that may or may not be associated with complementary and alternative medicine (CAM) modalities such as:

Western medicine and science has created some wonderfully useful ways of treating diseases and developing skills in surgery. Our goal should be not to replace conventional medicine, but to expand its boundaries and build a scientific foundation for integrating less well understood approaches to improve the functional status of patients and to provide a range of validated treatment options.

The medical profession is confronted by changing community attitudes, so a growing awareness of such therapies by the medical profession would seem to be in harmony with the growing public awareness for a more holistic form of health care.

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.

The World Health Organization (WHO) definition for optimal health suggests this should be inclusive of physical, social, psychological, emotional and spiritual wellbeing. The holistic or health model looks at maximising or supporting all aspects of a person’s health, which will then lead to the disease being healed by the body.

The health practitioner’s aim is to help empower patients to be active participants in their own healing process and to encourage personal responsibility for their health to improve quality of care and quality of life. The goal is not just to treat the illness, but to focus on promoting health and wellness.

Establishing and maintaining optimal health and balance is vital to prevention and treatment. Wellness is a state of being healthy characterised by positive emotions, thoughts and actions. Wellness is inherent in everyone, no matter what ‘disease’ is present. If wellness is truly recognised, focused upon and experienced, the individual will heal more quickly, not just through direct treatment of the ‘disease’ alone.

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

It is important to remain open-minded and flexible, both philosophically and in research methodology, with such an approach to treating individuals. We must recognise that healing primarily comes from the individual and mostly depends on their motivation level.

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 embraces a holistic approach to clinical practice encouraging patient involvement in self-health care, prevention and interventions that focus on health maintenance by paying attention to all relative components of lifestyle, including diet, exercise, stress management, and the emotional wellbeing of the patient. IM also integrates evidence-based complementary medicines that are safe and may positively impact on the healing process and quality of life for the patient.

IM does not reject or compete with conventional health care but rather seeks to broaden conventional health care by providing the health practitioner, doctor and patient with options to improve health that can work alongside conventional health care.

IM emphasises a number of issues including:9

When considering any therapy it is important to balance the risks, the benefits, the evidence, the costs, and the alternatives, such as other therapies or doing nothing.

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

Table 1.1 NCCAM classifications 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.
