ABSTRACT
BACKGROUND: We aimed to investigate whether students at German medical schools participating in elective courses on acupuncture and homeopathy differ from an unselected group of students regarding attitudes and personality traits. METHODS: Elective courses on acupuncture and homeopathy in the academic half-year 2013/14 all over Germany were identified and participants invited to fill in a questionnaire including nineteen questions on attitudes towards Complementary and Alternative Medicine (CAM), orientation towards science, care and status orientation, and a short validated instrument (Big-Five-Inventory-10) to measure personality traits (extraversion, neuroticism, openness, conscientiousness, and agreeableness). Participants of a mandatory family medicine course at one university served as unselected control group. RESULTS: Two hundred twenty and 113 students from elective courses on acupuncture and homeopathy, respectively, and 315 control students participated (response rate 93%). Students participating in elective courses had much more positive attitudes towards CAM, somewhat lower science and status orientation, and somewhat higher care orientation than control group students (all p-values for three-group comparisons < 0.001). There were no differences between the three groups regarding personality traits with the exception of lower values for agreeableness in controls (p = 0.009). CONCLUSIONS: The findings of this study show that attitudes of students participating in elective courses on acupuncture or homeopathy at German medical schools differ to a considerable degree from the attitudes of unselected students.

BACKGROUND: We aimed to investigate why medical students in Germany participate in elective courses on acupuncture or homeopathy. METHODS: The study was a nationwide, cross-sectional survey. Elective courses on acupuncture and homeopathy in the academic half-year 2013/14 were identified by inquiries directed to all 37 German medical schools, to student initiatives, and organizations supporting such courses. Participants of courses were asked to fill in a questionnaire consisting of a free-text question on their motives and closed questions regarding personal experiences, personal environment, evidence, role of the therapy as a complement to conventional medicine, and opportunistic aspects in relation to the therapy chosen. RESULTS: Students participating in 16 of 18 identified acupuncture courses (n = 220) and 12 of 13 identified homeopathy courses (n = 113) filled in the questionnaire. Content analysis of the free text showed that personal experience, a feeling that conventional medicine is somehow incomplete, the belief that acupuncture or homeopathy could help to overcome this shortcoming, and positive characteristics attributed to the therapies were the main motives for participation. Quantitative analyses showed that own experiences and considering the therapy a useful complement to conventional medicine were similarly rated motives in both groups, while opportunistic aspects played almost no role. The influence of the personal environment was more important among homeopathy students, while acupuncture students considered their therapy better backed by evidence. CONCLUSION: In our survey, personal experiences and the belief that acupuncture or homeopathy allows grasping the patient more holistically were primary motives for participation.

Homeopathy is a 200-year-old therapeutic system that uses small doses of various substances to stimulate autoregulatory and self-healing processes. Homeopathy selects substances by matching a patient's symptoms with symptoms produced by these substances in healthy individuals. Medicines are prepared by serial dilution and shaking, which proponents claim imprints information into water. Although many conventional physicians find such notions implausible, homeopathy had a prominent place in 19th-century health care and has recently undergone a worldwide revival. In the United States, patients who seek homeopathic care are more affluent and younger and more often seek treatment for subjective symptoms than those who seek conventional care. Homeopathic remedies were allowed by the 1939 Pure Food and Drug Act and are available over the counter. Some data--both from randomized, controlled trials and laboratory research--show effects from homeopathic remedies that contradict the contemporary rational basis of medicine. Three independent systematic reviews of placebo-controlled trials on homeopathy reported that its effects seem to be more than placebo, and one review found its effects consistent with placebo. There is also evidence from randomized, controlled trials that homeopathy may be effective for the treatment of influenza, allergies, postoperative ileus, and childhood diarrhea. Evidence suggests that homeopathy is ineffective for migraine, delayed-onset muscle soreness, and influenza prevention. There is a lack of conclusive evidence on the effectiveness of homeopathy for most conditions. Homeopathy deserves an open-minded opportunity to demonstrate its value by using evidence-based principles, but it should not be substituted for proven therapies.

Systematic reviews are considered the most reliable tool to summarize existing evidence. To determine whether reviews that address the same questions can produce different answers we examined systematic reviews of herbal medicine, homeopathy, and acupuncture taken from a previously established database. Information on literature searching, inclusion criteria, selection process, quality assessment, data extraction, methods to summarize primary studies, number of included studies, results and conclusions was compared qualitatively. Seventeen topics (eight on acupuncture, six on herbal medicines, three on homeopathy) had been addressed by 2-5 systematic reviews each. The number of primary studies in the reviews varied greatly within most topics. The most obvious reason for discrepancies between the samples was different inclusion criteria (in thirteen topics). Methods of literature searching may have contributed with some topics but the equivalence of the searches was difficult to assess. Differences were frequently observed in other methodological aspects, in results and in conclusions. This analysis shows that, at least in the three areas examined, systematic reviews often differ considerably. Readers should be aware that apparently minor decisions in the review process can have major impact.

BACKGROUND: The specific clinical benefit of the homeopathic consultation and of homeopathic remedies in patients with depression has not yet been investigated. AIMS: To investigate the 1) specific effect of individualized homeopathic Q-potencies compared to placebo and 2) the effect of an extensive homeopathic case taking (case history I) compared to a shorter, rather conventional one (case history II) in the treatment of acute major depression (moderate episode) after six weeks. METHODS: A randomized, partially double-blind, placebo-controlled, four-armed trial using a 2×2 factorial design with a six-week study duration per patient was performed. RESULTS: A total of 44 from 228 planned patients were randomized (2â¶1â¶2â¶1 randomization: 16 homeopathic Q-potencies/case history I, 7 placebo/case history I, 14 homeopathic Q-potencies/case history II, 7 placebo/case history II). Because of recruitment problems, the study was terminated prior to full recruitment, and was underpowered for the preplanned confirmatory hypothesis testing. Exploratory data analyses showed heterogeneous and inconclusive results with large variance in the sample. The mean difference for the Hamilton-D after 6 weeks was 2.0 (95%CI -1.2;5.2) for Q-potencies vs. placebo and -3.1 (-5.9;-0.2) for case history I vs. case history II. Overall, no consistent or clinically relevant results across all outcomes between homeopathic Q-potencies versus placebo and homeopathic versus conventional case taking were observed. The frequency of adverse events was comparable for all groups. CONCLUSIONS: Although our results are inconclusive, given that recruitment into this trial was very difficult and we had to terminate early, we cannot recommend undertaking a further trial addressing this question in a similar setting. Prof. Dr. Claudia Witt had full access to all the data in the study and takes responsibility for the integrity of the data and the accuracy of the data analysis.

BACKGROUND: Homeopathy is often sought by patients with depression. In classical homeopathy, the treatment consists of two main elements: the case history and the prescription of an individually selected homeopathic remedy. Previous data suggest that individualized homeopathic Q-potencies were not inferior to the antidepressant fluoxetine in a sample of patients with moderate to severe depression. However, the question remains whether individualized homeopathic Q-potencies and/or the type of the homeopathic case history have a specific therapeutical effect in acute depression as this has not yet been investigated. The study aims to assess the two components of individualized homeopathic treatment for acute depression, i.e., to investigate the specific effect of individualized Q-potencies versus placebo and to investigate the effect of different approaches to the homeopathic case history. METHODS/DESIGN: A randomized, partially double-blind, placebo-controlled, four-armed trial using a 2 x 2 factorial design with a six-week study duration per patient will be performed. 228 patients diagnosed with major depression (moderate episode) by a psychiatrist will be included. The primary endpoint is the total score on the 17-item Hamilton Depression Rating Scale after six weeks. Secondary end points are: Hamilton Depression Rating Scale total score after two and four weeks; response and remission rates, Beck Depression inventory total score, quality of life and safety at two, four and six weeks. Statistical analyses will be by intention-to-treat. The main endpoint will be analysed by a two-factorial analysis of covariance. Within this model generalized estimation equations will be used to estimate differences between verum and placebo, and between both types of case history. DISCUSSION: For the first time this study evaluates both the specific effect of homeopathic medicines and of a homeopathic case taking in patients with depression. It is an attempt to deal with the challenges of homeopathic research and the results might be useful information in the current discussion about the evidence on homeopathy TRIAL REGISTRATION: ClinicalTrials.gov: NCT01178255.

OBJECTIVE: To investigate to which extent physicians participating in specialization and continuing medical education courses read clinical research articles and how relevant they deem this for their practical work. METHODS: Physicians participating in courses on homeopathy (n = 96), acupuncture (n = 79), naturopathy (n = 75), family medicine (n = 50) and internal medicine (n = 136) filled in a questionnaire. They were asked to what extent and how they kept themselves informed about clinical research, how their daily work was affected by clinical research and why they did not spend more time reading clinical research literature. RESULTS: More than half of the participants (51%) reported they did not spend any time reading original research articles. Differences between the five groups of physicians were small. The proportion of physicians who considered the relevance of clinical trials for practical work as high or very high was 52% among participants of courses on homeopathy, 68% on acupuncture, 67% on naturopathy, 63% on family medicine and 81% in the internal medicine event. In all groups of physicians the relevance of clinical trials and meta-analyses to daily work was rated lower than that of personal experience, advice from colleagues, continuing medical education events, pathophysiological explanations, textbooks and guidelines. The large amount of time required to read original articles was reported as a major reason for the limited interest in clinical research. CONCLUSION: Among the physicians participating in this survey clinical trials and meta-analyses were only of subordinate relevance for clinical decision making.

The international review board was set up as the scientific advisory body of the Swiss Complementary Medicine Evaluation Programme (PEK) in 2002. It has met several times and has given advice with respect to the most important aspects of the programme. It would have been the normal procedure for the review board to have had the opportunity to comment on the drafts of the final scientific products as well as the draft of the summary report, in order to advise on them, before the documents became publicly available and formed the basis for political decision making. But the responsible authorities changed this process. In the following, the review board comments both on this process and on the products.

An analysis was made of papers reviewing controlled clinical trials designed to assess efficacy of homoeopathic treatment strategies, the aim being to demonstrate selective and critical assessment of such papers. The papers were systematically collected and evaluated for content and quality using predefined criteria, finally comparing the results. 9 of 41 papers considered in detail after screening the literature met the criteria for inclusion in the analysis. Each considered between 22 and 107 trials. 7 papers met 2 or less of the predefined quality criteria, one met 6 one 8 criteria. Only 1 of the papers allowed full representation and reproducible evaluation of treatment strategies for the controlled clinical studies considered in that paper. The analysis has shown that review papers must clearly specify issues, objectives, methods of literature screening and quality assessment
