Static magnetic field therapy: A critical review of treatment parameters

Static magnetic field (SMF) therapy, applied via a permanent magnet attached to the skin, is used by people worldwide for self-care. Despite a lack of established SMF dosage and treatment regimens, multiple studies are conducted to evaluate SMF therapy effectiveness. Our objectives in conducting this review are to:(i) summarize SMF research conducted in humans; (ii) critically evaluate reporting quality of SMF dosages and treatment parameters and (iii) propose a set of criteria for reporting SMF treatment parameters in future clinical trials. We searched 27 electronic databases and reference lists. Only English language human studies were included. Excluded were studies of electromagnetic fields, transcranial magnetic stimulation, magnets placed on acupuncture points, animal studies, abstracts, posters and editorials. Data were extracted on clinical indication, study design and 10 essential SMF parameters. Three reviewers assessed quality of reporting and calculated a quality assessment score for each of the 10 treatment parameters. Fifty-six studies were reviewed, 42 conducted in patient populations and 14 in healthy volunteers. The SMF treatment parameters most often and most completely described were site of application, magnet support device and frequency and duration of application. Least often and least completely described were characteristics of the SMF: magnet dimensions, measured field strength and estimated distance of the magnet from the target tissue. Thirty-four (61%) of studies failed to provide enough detail about SMF dosage to permit protocol replication by other investigators. Our findings highlight the need to optimize SMF dosing parameters for individual clinical conditions before proceeding to a full-scale clinical trial.

Utilization of Group-Based, Community Acupuncture Clinics: A Comparative Study with a Nationally Representative Sample of Acupuncture Users

OBJECTIVES Acupuncture utilization in the United States has increased in recent years, but is less common among racial/ethnic minorities and those of low socioeconomic status. Group-based, community acupuncture is a delivery model gaining in popularity around the United States, due in part to low-cost treatments provided on a sliding-fee scale. Affordable, community-based acupuncture may increase access to health care at a time when increasing numbers of people are uninsured. To assess the population using local community acupuncture clinics, sociodemographic factors, health status, and utilization patterns compared to national acupuncture users were examined. DESIGN Data were employed from (1) a cross-sectional survey of 478 clients of two community acupuncture clinics in Portland, Oregon and (2) a nationally representative sample of acupuncture users from the 2007 National Health Interview Survey. RESULTS Portland community acupuncture clients were more homogeneous racially, had higher educational attainment, lower household income, and were more likely to receive 10 or more treatments in the past 12 months (odds ratio=5.39, 95% confidence interval=3.54, 8.22), compared to a nationally representative sample of U.S. acupuncture users. Self-reported health status and medical reasons for seeking acupuncture treatment were similar in both groups. Back pain (21%), joint pain (17%), and depression (13%) were the most common conditions for seeking treatment at community acupuncture clinics. CONCLUSIONS Study findings suggest that local community acupuncture clinics reach individuals of a broad socioeconomic spectrum and may allow for increased frequency of treatment. Limited racial diversity among community acupuncture clients may reflect local demographics of Portland. In addition, exposure to and knowledge about acupuncture is likely to vary by race and ethnicity. Future studies should examine access, patient satisfaction, frequency of treatment, and clinical outcomes of group-based models of community acupuncture clinics located in racially and socioeconomically diverse communities.

A train the trainer model for integrating evidence-based medicine into a complementary and alternative medicine training program

BACKGROUND Public interest in complementary and alternative medicine (CAM) has grown over the past decade, accompanied by increased demand for evidence-based approaches to CAM practice. In order to define the role evidence-based decision making has in CAM practice, CAM professionals must have a full understanding of evidence-based medicine (EBM) concepts. OBJECTIVE This paper describes the design, implementation, and evaluation of a week-long intensive EBM short course for CAM faculty at a naturopathic and classical Chinese medicine institution. INTERVENTION This 20-hour course, entitled Principles of EBM for CAM Professionals, teaches participants how to access and appraise biomedical literature, apply it to their work, and teach these concepts to their students. RESULTS Results from precourse and postcourse evaluations suggest that, in a small group of participants, there were significant changes in EBM practice attitudes, self-appraised skills, and objectively assessed skills as a result of this course. Participants indicated they were committed to increasing their use of EBM in practice, enhancing EBM skills, using EBM in teaching, and working to change the culture at their institution to support use of EBM. At six months, 80% of participants had fully or partially followed through on their commitment to change plans.

The Vanguard Faculty Program: Research Training for Complementary and Alternative Medicine Faculty

BACKGROUND The increasing use of complementary and alternative medicine (CAM) treatment is paralleled by a growing demand for an evidence-based approach to CAM practice. In 2007, the Helfgott Research Institute at the National College of Natural Medicine (NCNM), in partnership with Oregon Health & Science University (OHSU), both in Portland, OR, began a National Institutes of Health-funded initiative to increase the quality and quantity of evidence-based medicine (EBM) content in the curricula at NCNM. DESIGN One key strategy of the Research in Complementary and Alternative Medicine Program (R-CAMP) initiative was to create a faculty development program that included four components: intensive training in EBM; professional skills enhancement; peer and mentored support; and, ultimately, utilization of these skills to incorporate EBM into the curricula. This initiative is centered on a core group of faculty at NCNM, called the Vanguard Faculty, who receives early, intensive training in EBM and works to incorporate this training into classes. Training consists of an intensive, week-long course, monthly group meetings, and periodic individualized meetings. Vanguard Faculty members also receive mentorship and access to resources to pursue individualized faculty development, research or scholarly activities. CONCLUSIONS Early evaluations indicate that this effort has been successful in increasing EBM content in the curricula at NCNM. This article describes the Vanguard Faculty program in an effort to share the successes and challenges of implementing a wide-ranging faculty development and curricular initiative at a complementary and alternative medicine institution.

Patient perspectives on care received at community acupuncture clinics: a qualitative thematic analysis.

BackgroundCommunity acupuncture is a recent innovation in acupuncture service delivery in the U.S. that aims to improve access to care through low-cost treatments in group-based settings. Patients at community acupuncture clinics represent a broader socioeconomic spectrum and receive more frequent treatments compared to acupuncture users nationwide. As a relatively new model of acupuncture in the U.S., little is known about the experiences of patients at community acupuncture clinics and whether quality of care is compromised through this high-volume model. The aim of this study was to assess patients’ perspectives on the care received through community acupuncture clinics.MethodsThe investigators conducted qualitative, thematic analysis of written comments from an observational, cross-sectional survey of clients of the Working Class Acupuncture clinics in Portland, Oregon. The survey included an open-ended question for respondents to share comments about their experiences with community acupuncture. Comments were received from 265 community acupuncture patients.ResultsQualitative analysis of written comments identified two primary themes that elucidate patients’ perspectives on quality of care: 1) aspects of health care delivery unique to community acupuncture, and 2) patient engagement in health care. Patients identified unique aspects of community acupuncture, including structures that facilitate access, processes that make treatments more comfortable and effective and holistic outcomes including physical improvements, enhanced quality of life, and empowerment. The group setting, community-based locations, and low cost were highlighted as aspects of this model that allow patients to access acupuncture.ConclusionsPatients’ perspectives on the values and experiences unique to community acupuncture offer insights on the quality of care received in these settings. The group setting, community-based locations, and low cost of this model potentially reduce access barriers for those who might not otherwise consider using acupuncture. In addition, the community acupuncture model may offer individuals the opportunity for increased frequency of treatments, which raises pertinent questions about the dose–response relationship of acupuncture and health outcomes. This study provides preliminary data for future evaluations of the quality and effectiveness of community acupuncture. Future studies should include the perspectives of patients who initiated, and subsequently, discontinued community acupuncture treatment.

Expectancy, Self-Efficacy, and Placebo Effect of a Sham Supplement for Weight Loss in Obese Adults

This study examined the role of expectancy in the placebo effect of a sham dietary supplement for weight loss in 114 obese adults with metabolic syndrome. All participants received lifestyle education and were randomized to 1 of 3 conditions: (1) a daily placebo capsule and told that they were taking an active weight loss supplement, (2) daily placebo and told they had a 50% random chance of receiving either the active or placebo, or (3) no capsules. At 12 weeks, weight loss and metabolic outcomes were similar among the 3 groups. Participants in both groups that took capsules showed decreased weight loss self-efficacy and increased expectations of benefit from dietary supplements. Participants not taking capsules showed the opposite. Adverse events were more frequently reported in groups taking capsules than those who were not. These findings suggest that supplements without weight loss effects may have nocebo effects through diminished self-efficacy.

P05.37. Assessing patient perspectives on quality of care at community acupuncture clinics
