Multischool, international survey of medical students' attitudes toward "holism".

PURPOSE: Core and optional courses of study in complementary and alternative medicine (CAM) are being incorporated into medical curricula. The authors carried out this study to validate a tool to examine students' attitudes toward holism and CAM and explore the relationships between their attitudes and other demographic and education-related characteristics in a large, multischool, international sample of medical students. METHOD: In 2003 the authors used a modified version of the Integrated Medicine Attitude Questionnaire (IMAQ) to survey students at a total of six medical schools in the United Kingdom, New Zealand, Canada, the United States, and Hong Kong, China. A three-factor model was tested using confirmatory factor analysis, and the internal consistency of the factors were identified using Cronbach's alpha coefficients. A multiple-indicator multiple-cause (MIMIC) analysis was carried out to determine the relationship between IMAQ factors and student characteristics. RESULTS: The authors validated a three-factor model for the IMAQ: (1) attitudes toward holism, (2) attitudes toward the effectiveness of CAM, and (3) attitudes toward introspection and the doctor-patient relationship. Cronbach's alpha coefficients ranged from .41 to .71. The MIMIC model indicated that various background variables were associated with IMAQ factors (gender, race/ethnicity, and school), depending on whether students had previously visited a CAM practitioner and whether students were willing to undertake a special study module in CAM. CONCLUSIONS: Further development work on the IMAQ is required and qualitative research to verify and examine the reasons behind the relationships found in this study between students' attitudes to holism and their demographic and education-related characteristics.

Safety review of kava (Piper methysticum) by the Natural Standard Research Collaboration.

This systematic review discusses the proposed uses, dosing parameters, adverse effects, toxicology, interactions and mechanism of action of kava. The widespread concern regarding the potential hepatotoxicity of kava is discussed. A recommendation is made to consolidate and analyse available reports and to continue postmarket surveillance in an international repository to prevent duplicates and promote collection of thorough details at the time of each report so that any association with kava is clearly defined.

Characteristics of pediatric and adolescent patients attending a naturopathic college clinic in Canada.

OBJECTIVES: The use of complementary and alternative medicine (CAM) has grown substantially in North America and has drawn the attention of conventional-medicine practitioners. Conventional-medicine practitioners have expressed concern about the potential for unregulated CAM therapies to cause harm, the sometimes-uncertain cost-benefit ratios associated with these therapies, and the possibility that some CAM providers might advise against established conventional therapies, such as vaccination. These concerns are heightened with respect to the pediatric use of CAM products. To address this issue, we conducted a systematic audit of pediatric and adolescent case files at a large, college-based, Canadian naturopathic teaching clinic. We specifically sought to describe the demographic characteristics, reasons for presentation, use of CAM products, and vaccinations status of children presenting for naturopathic assessment. We also determined factors associated with the use of CAM products and vaccination status. METHODS: We identified all charts for children (<18 years of age) who presented to the Robert Schad Naturopathic Clinic, the teaching clinic of the Canadian College of Naturopathic Medicine, between February 1 and May 31, 2002. Data were abstracted directly from the standardized patient intake forms and from clinical notes recorded during the patient's initial visit to the clinic. The following data were obtained: age, gender, chief presenting complaints reported by parents, CAM product use at presentation, vaccination status, and reactions to vaccination. We conducted logistic regression analyses to identify factors associated with both CAM product use and vaccination status. RESULTS: A total of 482 charts were identified. The mean age of patients was 6.5 years (95% confidence interval [CI]: 1.6-11.4 years). The ratio of female subjects to male subjects was 1.09:1 (248:227). The most common reasons for presentation were skin disorders (23%), gastrointestinal complaints (17%), and psychiatric/behavioral disorders (15%). Thirty-five percent of children were using CAM products at presentation (21.2% when both vitamins and minerals were excluded). Vitamins were the most commonly used products (34.6%), followed by herbal remedies (14.9%), oil blends/fats (7.2%), minerals (5.6%), probiotics (4.5%), and homeopathic remedies (3.7%). Of charts with vaccination information, 8.9% indicated that children had not been vaccinated; possible vaccine-associated adverse events were reported for 27% of those who had been vaccinated. Partial or unvaccinated status was associated with younger age, attending the Canadian College of Naturopathic Medicine for advice regarding vaccination, and greater use of CAM products. CAM product use was associated with unvaccinated or partially vaccinated status (odds ratio [OR]: 2.86; 95% CI: 1.46-5.63), presenting with poor energy or fatigue (OR: 3.36; 95% CI: 1.00-11.26), or presenting with throat or sinus infections (OR: 4.06; 95% CI: 1.23-13.04). CONCLUSIONS: Children present for naturopathic assessment for diverse reasons, are high-level consumers of CAM products, and have lower rates of vaccination than population averages. The conventional-medicine community should work with naturopaths to address public health concerns in this population.

From parallel practice to integrative health care: a conceptual framework.

BACKGROUND: "Integrative health care" has become a common term to describe teams of health care providers working together to provide patient care. However this term has not been well-defined and likely means many different things to different people. The purpose of this paper is to develop a conceptual framework for describing, comparing and evaluating different forms of team-oriented health care practices that have evolved in Western health care systems. DISCUSSION: Seven different models of team-oriented health care practice are illustrated in this paper: parallel, consultative, collaborative, coordinated, multidisciplinary, interdisciplinary and integrative. Each of these models occupies a position along the proposed continuum from the non-integrative to fully integrative approach they take to patient care. The framework is developed around four key components of integrative health care practice: philosophy/values; structure, process and outcomes. SUMMARY: This framework can be used by patients and health care practitioners to determine what styles of practice meet their needs and by policy makers, healthcare managers and researchers to document the evolution of team practices over time. This framework may also facilitate exploration of the relationship between different practice models and health outcomes.

A survey of attitudes towards paediatric vaccinations amongst Canadian naturopathic students.

Previous studies have suggested that providers of alternative medicine may harbour anti-vaccination attitudes and that these attitudes may develop at an early stage in their careers. We further explored this question by conducting a survey to determine the attitudes of students of naturopathic medicine, a growing alternative medicine discipline, towards recommended paediatric vaccines. We sampled all 4 years of students at the Canadian College of Naturopathic Medicine (CCNM) and obtained a response rate of 59.4% (312 of 525). We found that only 12.8% (40 of 312) of the respondents would advise full vaccination; however, 74.4% (232 of 312) of the respondents would advise partial vaccination. Importantly, both willingness to advise full vaccination and trust in public health and conventional medicine decreased in students in the later years of the programme. Our findings suggest that public health and conventional medical supporters of vaccination need to identify mechanisms for engaging in discussion with this population of complementary/alternative medical professionals at an early stage in their careers.

Responses of established healthcare to the professionalization of complementary and alternative medicine in Ontario.

This paper examines the reactions of leaders of established health professions in Ontario, Canada to the efforts of selected complementary and alternative (CAM) occupational groups (chiropractors, naturopaths, acupuncture/traditional Chinese doctors, homeopaths and Reiki practitioners) to professionalize. Stakeholder theory provides the framework for analysis of competing interests among the various groups in the healthcare system. The data are derived from personal interviews with 10 formal leaders from medicine, nursing, physiotherapy, clinical nutrition and public health. We conceived of these leaders as one group of stakeholders, with both common and conflicting interests. The findings demonstrate that these stakeholders are reluctant to endorse the professionalization of CAM. They propose a series of strategies to contain the acceptance of CAM groups, such as insisting on scientific evidence of safety and efficacy, resisting integration of CAM with conventional medicine and opposing government support for research and education. These strategies serve to protect the dominant position of medicine and its allied professions, and to maintain existing jurisdictional boundaries within the healthcare system. The popular support for CAM will require that health professional stakeholders continue to address the challenges this poses, and at the same time protect their position at the apex of the healthcare pyramid.

Moving forward? Complementary and alternative practitioners seeking self-regulation.

Complementary and alternative medicine (CAM) occupations continue to struggle towards achieving professional status, especially in the form of statutory regulation. Many consider professional status a worthwhile goal for CAM occupations, yet it is a process fraught with tensions. In this paper we present in-depth interview data from the leaders of three CAM groups (naturopaths, traditional Chinese medicine practitioners acupuncturists, and homeopaths) in Ontario, Canada that demonstrate four main strategies used by these groups to professionalize. The strategies discussed are related to how the knowledge base of each group is organised and transmitted. These strategies include: improving educational standards, improving practice standards, engaging in peer-reviewed research and increasing group cohesion. At the core of these strategies is the demarcation of who is qualified to practice, and a signalling to 'outsiders', such as medicine and the government, that practitioners are qualified and legitimate. Across the three groups, the leaders referred to the inclusion of medical science as a basis for distinguishing between 'science' and 'non-science' as well as who should practice and who should not. We highlight how internal battles over the infusion of medical science into the knowledge base are part of the process for establishing legitimacy for the three CAM groups in our study. We end with a brief discussion of the implications of these internal battles over medical science knowledge for the future of CAM groups.

Botanical medicine and cancer: a review of the safety and efficacy.

It is currently estimated that > 50% of all patients diagnosed with cancer explore complementary and alternative medicine - especially herbal medicine. We conducted a comprehensive review to assess the safety and efficacy of herbal medicines commonly used by patients in an attempt to: prevent cancer; treat cancer; and treat adverse effects associated with conventional cancer treatments. Current evidence suggests that Asian ginseng, garlic, green tea, tomatoes and soy intake as part of the diet may be useful in preventing various cancers; additional research is needed in order to determine the efficacy of essiac, evening primrose oil, mistletoe, reishi, shiitake and turmeric as cancer treatments; and ginger may be effective in treating chemotherapy-induced nausea and vomiting.

Effects of greens+: a randomized, controlled trial.

Greens+ is a popular natural health product marketed as energy-enhancing; however, no objective data substantiate this claim. The study objective was to determine if ingestion of greens+ 1. increases vitality, energy, and perception of well-being; 2. increases overall mental health and general health, and 3. decreases the incidence of colds and flus in an otherwise healthy female population. A total of 105 women were enrolled in this 12-week, randomized, double-blind, placebo-controlled clinical trial; 63 (60%) completed the treatment protocol. Both treatment and placebo groups showed a significant time trend effect, scoring better on all outcome measures as the trial progressed. Compared with the placebo group, the greens+ group scored marginally higher on vitality, the primary outcome measure (p=0.055), and significantly higher on energy (a secondary outcome measure, p=0.018). Findings were based on repeated measures analysis of variance; baseline scores were used as covariates. Although a trend toward greater improvement in the greens+ group was noted in the other secondary outcome measures, this trend did not reach statistical significance. Overall, our findings were positive but not conclusive that greens+ increases vitality and energy. These results provide justification for further study of the effects of greens+.

Use of complementary/alternative medicine by men diagnosed with prostate cancer: prevalence and characteristics.

OBJECTIVES: To ascertain the prevalence of the use of complementary/alternative medicine (CAM) among a random sample of Ontario (Canadian) men diagnosed with prostate cancer and to explore in what way users of CAM differ from nonusers. METHODS: A questionnaire was mailed to a random sample of 696 men diagnosed with prostate cancer. RESULTS: The final response rate was 78.8%. Almost one third (29.8%) reported using CAM for their prostate cancer care. Natural health products (most commonly vitamin E, saw palmetto, and selenium) were used by 26.5% of the respondents. CAM therapies were used by 17.0% of the men (most commonly dietary changes), and only 9.1% visited CAM practitioners. Three characteristics appear to differentiate CAM users from nonusers. Men who had attended support groups were much more likely to use CAM. Men who had more advanced disease, and those who believed in the efficacy of CAM, but were not concerned about potential adverse effects of CAM, were also more likely to use CAM. CAM use was not related to education, income, or geographic location. CONCLUSIONS: The data suggest that CAM use is no longer a phenomenon restricted to a unique segment of the population that is highly educated and enjoys a high family income. CAM use appears to be more related to other factors such as support group attendance, disease characteristics, and beliefs about CAM. Our findings highlight the need for urologists to ask all their patients about their use of CAM.

Acupuncture as a promising treatment for below-level central neuropathic pain: a retrospective study.

BACKGROUND/OBJECTIVE: Below-level central neuropathic pain, a diffuse pain characterized by generalized burning, is commonly experienced by individuals with spinal cord injury (SCI). The objective of this study was to investigate the effects of an electroacupuncture protocol for the treatment of below-level central neuropathic pain developed at the Toronto Rehabilitation Institute, Lyndhurst Center, Toronto, Ontario, Canada. METHOD: Retrospective chart review. RESULTS: Thirty-six individuals with traumatic and nontraumatic SCI met the inclusion criteria. Of these, 24 showed improvement after treatment with the electroacupuncture protocol. Type of injury, level of injury, and duration of below-level central neuropathic pain was not correlated with improvement. However, individuals whose pain was described as bilateral (vs unilateral; P = 0.014) or symmetric (vs nonsymmetric; P = 0.026) were more likely to improve after acupuncture treatment. Overall, patients whose burning pain was bilateral, symmetric, and constant (P = 0.005) were the most likely to improve. CONCLUSION: This retrospective study suggests that the Lyndhurst Center Central Neuropathic Pain Acupuncture Protocol may be an effective treatment option for patients with SCI who are experiencing below-level central neuropathic pain. Additional prospective clinical studies are needed to confirm these findings.

Visiting family physicians and naturopathic practitioners. Comparing patient-practitioner interactions.

OBJECTIVE: To explore similarities and differences in patient visits with family physicians (FPs) and naturopathic practitioners (NPs). DESIGN: Exploratory study combining quantitative and qualitative methods. SETTING: Southern Ontario. PARTICIPANTS: A purposeful sample of 10 practitioners (five FPs and five NPs matched for age, sex, and number of years in practice): each agreed to recruit three consecutive patients with new complaints to participate in the study. MAIN OUTCOME MEASURES: Patient and visit characteristics; qualitative (content analysis of audiotaped interactions) and quantitative (ie, patient-centred care scores) information was gathered and analyzed. RESULTS: Qualitative analysis revealed that information gathering and treatment planning were very similar whether patients were visiting FPs or NPs. Most important differences were length of interaction (mean 54 minutes for NPs and 16.5 minutes for FPs) and patients' reasons for visits. Naturopathic practitioners were more likely to recommend medications (usually natural health products) than FPs. Quantitative data suggested that patients perceived no differences in patient-centred care from FPs and NPs. CONCLUSION: Overall, there were more similarities than differences in visits to the two types of practitioners.

Advising patients who seek complementary and alternative medical therapies for cancer.

Many patients with cancer use complementary and alternative medical (CAM) therapies. Physicians need authoritative information on CAM therapies to responsibly advise patients who seek these interventions. This article summarizes current evidence on the efficacy and safety of selected CAM therapies that are commonly used by patients with cancer. The following major categories of interventions are covered: dietary modification and supplementation, herbal products and other biological agents, acupuncture, massage, exercise, and psychological and mind-body therapies. Two categories of evidence on efficacy are considered: possible effects on disease progression and survival and possible palliative effects. In evaluating evidence on safety, two types of risk are considered: the risk for direct adverse effects and the risk for interactions with conventional treatments. For each therapy, the current balance of evidence on efficacy and safety points to whether the therapy may be reasonably recommended, accepted (for example, dietary fat reduction in well-nourished patients with breast or prostate cancer), or discouraged (for example, high-dose vitamin A supplementation). This strategy allows the development of an approach for providing responsible, evidence-based, patient-centered advice to persons with cancer who seek CAM therapies.

The use of CAM by women suffering from nausea and vomiting during pregnancy.

BACKGROUND: Nausea and vomiting during pregnancy (NVP) affects two-thirds of pregnant women to varying degrees and over the years many modalities have been used to try to alleviate this often debilitating condition. There is a paucity of information in the literature about the use or efficacy of complementary and alternative medicine (CAM) for the treatment of this condition that affects so many women. Our primary objective was to examine the prevalence of CAM usage by women suffering from NVP. Our secondary objective was to ascertain if women had any supervision in the use of these treatments. METHODS: Women who called The Motherisk NVP helpline, were asked after the counseling session to complete a questionnaire, which included demographic data as well as information about their CAM use. RESULTS: Seventy women completed the questionnaire. 61% reported using CAM therapies, of which the three most popular were: ginger, vitamin B6 and acupressure. 21% of those who reported using CAM, had consulted CAM practitioners, 8% their physicians or pharmacists and 71% discussed the usage with family, friends and other allied health professionals. Women who did not use CAM stated they would probably use these modalities if there was more information about the safety in pregnancy. CONCLUSION: Pregnant women with NVP are mirroring the trend in the general population of the use of CAM. They are also using CAM therapies with little supervision from practitioners experienced in the use of these modalities.
