Integrative Medicine and Prospective Research on CAM

Introduction

The World Health Organization (WHO) Traditional Medicine Strategy 2014-2023 suggested promoting universal health coverage by integrating CAM into conventional medicine (World Health Organization, 2013). Three Asian countries provide full coverage of traditional medicine integrated into their national health system, i.e. China, South Korea and Vietnam. In Switzerland, partial integration of CAM is employed (World Health Organization, 2013). Integrative medicine (IM) is a new term in the CAM field, compared with the terms complementary or alternative medicine. There is no consensus on the definition of IM. One definition of this term focused on its meaning is ‘IM is the use of CAM integrated into conventional medicine, which should be supported by evidence’ (Walach, 2010). Hu et al. (2015) proposed five key elements of IM as described by an expert consensus: (1) presence of aspects of both CAM and conventional medicine; (2) goals of health and healing; (3) holistic approach; (4) optimum treatment; and (5) uses the body’s innate healing response.

Patients with chronic diseases tend to use CAM with their conventional medicine as they hope that CAM could complement it, including patients with kidney disease (Tangkiatkumjai et al., 2014). Several chronic diseases are frequently treated by IM, such as asthma, rheumatic disease, chronic inflammatory bowel disorder, and chronic pain (Dobos & Tao, 2011). Patients need to know how to integrate CAM with their conventional medicine in order to obtain both higher efficacy and lower adverse effects of conventional medicine. Both CAM and conventional systems have their own advantages and disadvantages, so their integration would be an option for some illnesses that cannot be fully treated by one system. CAM users and conventional practitioners are also concerned about the interaction between them, which may be either synergistic or antagonistic. Research on IM is therefore required to support clinical decision-making. This chapter will describe existing IM models, research on IM and a checklist for reporting research on IM. The section of prospective research on CAM methodologies will: (1) discuss a research approach to building up evidence for CAM; (2) highlight major issues of methodologies of randomised controlled trials (RCTs) in CAM/IM research; (3) propose plausible solutions for those issues; and (4) provide prospective research on CAM/IM in kidney diseases.
