Why offer Integrative Medicine?

8

Canadians are increasingly using CAM in conjunction with, not instead of conventional care.

• 12% of Canadians used some sort of CAM service within 12 months, Users tend to be female, high income and education, middle aged (Metcalfe et al. Univ of Calgary, BMC Comp and Alt Medi 2010) • 16% of children presenting to a Canadian emergency room were taking natural health products with potential drug interactions (Goldman et al. Univ of BC, J Ped 2008) • Canadians with arthritis/rheumatism, asthma, back problems, lung disease, Crohn’s, migraine more likely CAM users (Stat Canada Nat Pop Health Survey 1994-1999)

Patients seek CAMA when they feel they are missing something from the conventional system.

• 40% used CAM because they had problem communicating with their MD, 2/3 felt that conventional medicine was not as effective, patients wanted to be more active, holistic (Sirois FM, BMC 2008)

Patients don’t often disclose the use of CAM to their physicians.

• Canadian College of Naturopathic Medicine found that only 58.5% of patients discussed CAM use with their MD and 70% of MDs do not ask their patients about the use of CAM services. (Busse et al. Mayo Clin Proc 2005).

Integrative Medicine - Principles

Integrative Medicine is the combination of mainstream medicine (Conventional) with Complimentary Alternative Medicine (CAM) that have “high quality scientific evidence of safety and effectiveness.” 1. “Healing” – body is innately self-healing, power of nature 2. “Patient Centred Care” – holistic approach, doctor patient therapeutic relationship, communication, “transformational” component – mind, body, spirit 3. “Wellness” - Lifestyle Component – nutrition, physical activity, stress, sleep, spiritual, occupational functioning, prevention and wellness approach, positive behavioural change

National Institute of Health ( 5 classification )

1. Alternative Medicine – Chinese Medicine (acupuncture), Naturopathic Medicine, Ayurvedic, homeopathy 2. Biologic Based Therapies – herbal, special dietary, individual biologics not FDA approved 3. Energy Therapies – Reiki, therapeutic touch, magnet therapy, Qi Gong, intercessory prayer 4. Manipulative and Body Based Systems – chiropractic, osteopathy, massage 5. Mind-Body Interventions – meditation, biofeedback, hypnotherapy, relaxation response

Review of the Evidence – “Non Specific Effects / Placebo”

• Several reviews of non pharmacological interventions for chronic pain including cognitive behavioural therapy (CBT), exercise, acupuncture, spinal manipulation, diet, herbal supplements, massage. Clinical effectiveness strongest for exercise, CBT and mixed for acupuncture.

Non Specific Effects

1. Hawthorne Effect (patients response to observation and assessment) 2. Healing Effect (response to patient-physician interaction) 3. Placebo Effect (response to administration of a “dummy” treatment) • Placebo effect – 30% of patients respond to placebo for pain (Beecher JAMA 1955); Since then several studies have found between 27-56% respond to placebo .

• Verbal Suggestions (by the health practitioner) and Prevention Trials trigger larger placebo responses. • Variability of placebo responses may be dependent on cognitive factors and previous pain experiences.

• Publication of clinical trials is strongly biased in favour of interventions that outperform unspecific treatment effects. Future approach on “Whole System Research” (WSR) – focus on practitioner-patient relationship and therapeutic environment; pragmatic trials for assessments of individualized treatments Staud R.

Bottom Line: Ginkgo does not improve memory or cognitive functioning in healthy people. It was also found ineffective in decreasing the occurence of dementia or Alzheimer's disease in elderly individuals.

• Scientists have found that in animals and humans, ginkgo dilates blood vessels in the brain thereby, increasing blood flow to the brain. This enables the body to handle ischemic (low oxygen) conditions, which can help prevent tissue damage. In animal studies, ginkgo showed a beneficial effect on the tone of the smooth muscle found in arteries, maintaining their appropriate dilation and constriction. Experiments have also revealed that ginkgo can reduce inflammation and calm muscle spasms. As an antioxidant, it can also neutralize free radicals in the body, which cause cellular and DNA damage. Laboratory and animal experiments suggest that ginkgo can help prevent infections. Ginkgo also inhibits platelet-activating factor, which is important for blood clotting, and therefore has blood thinning qualities. Ginkgo supplementation may increase risk of stroke.

Lessons Learned

• Strategic Rollout with Physicians – Position statement on Medcan “Scope of Practice”, Workshops, CME events, Case Rounds, Medical Articles, Advisory Role with Johns Hopkins • Led by Naturopathic Doctors (regulated health professional, 4 years of training). Mix of academic, clinical ND (10 yr plus of experience) and ND familiar with Medcan (developed within the organization) • MDs have been supportive when collaboration required. Initially was concerned about requiring a MD “specialist” / champion.

• Relationship building between ND and MD team is critical. “One on one” discussions. Consults on shared care.

• 15 minute “free” consult with a naturopathic doctor. “What is Integrative Medicine?” Customize services.

• Relationship with Pharmacy Online Store to provide natural health products. Simplifies process and maintains a high level of client service.

• Marketing – Increased awareness amongst corporate clients. Newsletters, seminars, workshops to lay people. Website presence. Online video and FAQ.

• MDs are still trying to learn how to best co-manage care. Ongoing process.

Doctor Patient Relationship

• Determinants of the relationship (1) Longitudinal Care – same doctor; (2) Consultation Experiences – patient encounters; (3) Patient-Doctor Depth of Relationship • Determinants of Patient’s Perspective of the depth of the MD- Patient relationship include four elements –

KNOWLEDGE, TRUST, LOYALTY and REGARD

• Evidence on impact of patient satisfaction on patient outcomes is mixed.

Three different frameworks to evaluate with respect to Doctor Patient Relationship: 1. Communication Style (report on behavior of the health care provider – verbal and non verbal communication techniques) 2. Satisfaction Questionnaires (report fulfillment of one’s wishes, expectations or needs, thus making a judgement on past actions). 3. Relationship Questionnaires (assess emotions or sentiments elicited by contact between health care provider and patient) Ridd MJ et al.

• OBJECTIVES: We sought to determine the amount of time required for a primary care physician to provide recommended preventive services to an average patient panel. METHODS: We used published and estimated times per service to determine the physician time required to provide all services recommended by the US Preventive Services Task Force (USPSTF), at the recommended frequency, to a patient panel of 2500 with an age and sex distribution similar to that of the US population. RESULTS: To fully satisfy the USPSTF recommendations, 1773 hours of a physician's annual time, or 7.4 hours per working day, is needed for the provision of preventive services. CONCLUSIONS: Time constraints limit the ability of physicians to comply with preventive services recommendations.
