Demarcating scientific medicine.

Scientific medicine and homeopathy are interesting case studies for the ongoing project of demarcating science from pseudoscience. Much of the demarcation literature formulates abstract criteria for demarcating science from pseudoscience generally. In service of a more localist approach to the demarcation problem, I reconstruct a specific demarcating difference, the like comparison criterion, invoked by nineteenth century adherents to an early model of scientific medicine. If it is to remain relevant today, I argue that the like comparison criterion must be updated in our current era of epidemiological, evidence-based medicine to recognize the importance of assessing study bias and mechanistic implausibility in contemporary medical science.

A Broader Vision for Homeopathy: Medicine Needs Healing, and Homeopathy Has a Part to Play.

The controversial claim that homeopathic medicines actively stimulate the innate capacity of body and mind for healing and repair demands continuing and energetic investigation. But regardless of the outcome of this scientific controversy, the reported changes associated with applying the homeopathic method are matters of clinical fact. There is thus a case to be made that the homeopathic approach, the way that it studies and construes the experience of illness in individual patients, enriches our understanding of health, illness and healing; and is itself an essential contribution that homeopathy can make to the advancement of medicine. Practitioners and researchers involved in homeopathy can, and should, be more energetic and forceful in making that case.

Physiology, Vitalism, and the Contest for Body and Soul in the Antebellum United States.

In the early nineteenth century, physiology became an increasingly popular and powerful science in the United States. Religious controversy over the nature of human vitality animated much of this interest. On one side of these debates stood Protestant apologists who wedded an immaterialist vitalism to their belief in an immaterial, immortal soul - and therefore to their dreams of a Christian republic. On the other side, religious skeptics argued for a materialist vitalism that excluded anything immaterial from human life, aspiring thereby to eliminate religious interference in the progress of science and society. Both sides hoped that by claiming physiology for their vision of human nature they might direct the future of religion in the US. Ultimately, they failed to realize these ambitions, but their contest posed a dilemma late nineteenth-century physiologists felt compelled to solve: how should they comprehend the relationship between life, body, and soul? Eager to undertake laboratory work and leave metaphysical questions behind, these researchers solved the problem by restricting their work to the body while leaving spiritual matters to preachers. In attempting to escape the vitalism and soul questions, late nineteenth-century Americans thus created a division of labor that shaped the history of medicine and religion for the following century.

Routes into the homeopathic profession: Witnessing, gender and subaltern therapeutics.

Homeopathy, along with many other alternative therapies, has come under severe attack from apologists for orthodox medicine. Given the cultural authority of medicine, what then provides the impetus for people to take up homeopathy as a clinical practice? This article addresses this question in the context of homeopathic practice in New Zealand. Five focus groups were conducted with 22 homeopaths in five cities. The study found that it was common to be drawn to homeopathy through witnessing in themselves, their family, friends or animals, the positive effects of homeopathy, commonly after negligible success from conventional medicine. For many participants, all of whom were women, the opportunity to study homeopathy occurred when they were the primary carers of children, with homeopathy providing a possibility for a change in work trajectories. Many participants had previous occupations inside the conventional health system. Central to the appeal of homeopathy as a subaltern practice in New Zealand is the often dramatic impact of witnessing the effects of the therapeutic modality, which is conceptualised as analogous to an 'event' that tears at the fabric of the everyday.

Locating hygienic medicine within the intellectual history of hygiene: cases of E. W. Lane and T. R. Allinson.

Nineteenth century hygiene might be a confusing concept. On the one hand, the concept of hygiene was gradually becoming an important concept that was focused on cleanliness and used interchangeably with sanitation. On the other hand, the classical notions of hygiene rooted in the Hippocratic teachings remained influential. This study is about two attempts to newly theorise such a confusing concept of hygiene in the second half of the century by Edward. W. Lane and Thomas R. Allinson. Their works, standing on the borders of self-help medical advice and theoretical treatises on medical philosophies, were not exactly scholarly ones, but their medical thoughts - conceptualised as hygienic medicine - show a characteristically holistic medical view of hygiene, a nineteenth-century version of the reinterpretation of the nature cure philosophy and vitalism. However, the aim of this study is to properly locate their conceptualisations of hygienic medicine within the historical context of the second half of the nineteenth century rather than to simply introduce the medical ideas in their books. Their views of hygiene were distinguished not only from the contemporary sanitary approach but also from similar attempts by contemporary orthodox and unorthodox medical doctors. Through a chronological analysis of changes in the concept of hygiene and a comparative analysis of these two authors' and other medical professionals' views of hygiene, this paper aims to help understand the complicated picture of nineteenth-century hygiene, particularly during the second half of the century, from the perspective of medical holism and reductionism.

The Human Microbiome, Conventional Medicine, and Homeopathy.

Human health is intimately linked to the ecology and diversity of the human microbiome. Together, the human organism and the human microbiome work as a complex super-organism throughout the human life cycle. Microbiome science provides direct evidence and substantiation of the fundamental principles of homeopathy, including holism, psychosomatics, direction of cure, the Law of Similars, individuality and susceptibility, minimum dose, and homeostasis. Whilst many conventional (allopathic) medical treatments irreversibly damage the ecology of the microbiome and trigger chronic immune dysfunction and inflammation, the future sustainability of the entire field of medicine depends on the ability to recognize these inconvenient biological truths and to embrace a safer approach based on this evidence. Fortunately, one of the oldest forms of clinically verifiable, evidence-based, and ecologically sustainable medicine, that does not harm the microbiome, already exists in the form of homeopathy.

[Homeopathy: insubstantial doctrine of salvation]. / Homöopathie: Heilslehre "ohne Substanz".

Homeopathy is one of the frequently used alternative healing methods in Germany. This article is intended to discuss and analyze why homeopathy should not be part of medicine and should rather be understood as a concept of belief that lies outside of scientific methods. The clinical, legal, and political dimensions of the homeopathy debate are explained. Finally, the question of the legitimacy of placebo applications is discussed in light of the demand for patient-centered medicine.

'Unconventional' experiments in biology and medicine with optimized design based on quantum-like correlations.

In previous articles, a description of 'unconventional' experiments (e.g. in vitro or clinical studies based on high dilutions, 'memory of water' or homeopathy) using quantum-like probability was proposed. Because the mathematical formulations of quantum logic are frequently an obstacle for physicians and biologists, a modified modeling that rests on classical probability is described in the present article. This modeling is inspired from a relational interpretation of quantum physics that applies not only to microscopic objects, but also to macroscopic structures, including experimental devices and observers. In this framework, any outcome of an experiment is not an absolute property of the observed system as usually considered but is expressed relatively to an observer. A team of interacting observers is thus described from an external view point based on two principles: the outcomes of experiments are expressed relatively to each observer and the observers agree on outcomes when they interact with each other. If probability fluctuations are also taken into account, correlations between 'expected' and observed outcomes emerge. Moreover, quantum-like correlations are predicted in experiments with local blind design but not with centralized blind design. No assumption on 'memory' or other physical modification of water is necessary in the present description although such hypotheses cannot be formally discarded. In conclusion, a simple modeling of 'unconventional' experiments based on classical probability is now available and its predictions can be tested. The underlying concepts are sufficiently intuitive to be spread into the homeopathy community and beyond. It is hoped that this modeling will encourage new studies with optimized designs for in vitro experiments and clinical trials.

Seeking alternatives, asserting choices: Dr Mahendralal Sarkar's life in medicine and science.

This article examines the medical life of a native physician who embraced homoeopathy despite being trained in the dominant pathy i.e. allopathy at the prestigious Calcutta Medical College in the 1860s. Mahendralal Sarkar, the physician in focus, was one of the first famous converts to homoeopathy. His seeking of an alternative option created space and legitimacy for homoeopathy. Through the journal Calcutta Journal of Medicine that Sarkar founded, he, with great ability, asserted and defended his right as a physician to decide in favour of homoeopathy. Sarkar gradually established himself as an accomplished homoeopath and was recognised as an important public figure of Calcutta. The odds and opposition he faced convinced him to embark on a great task of the cultivation of science as, in his view, the inculcation of the spirit of science was the need of the day to break the orthodoxy and mitigate prejudices of the medical profession and society at large.

Veterinary Naturopathy and Complementary Medicine: A Survey among Homepages of German Veterinary Practitioners.

BACKGROUND: The use and interest in veterinary naturopathy and complementary medicine are increasing and modes of treatment are diverse. To this point, only a few data on the German situation in small animal medicine exist. MATERIAL AND METHODS: An online research of 1,083 German veterinary homepages for contents of veterinary naturopathy and complementary medicine was performed in September and October 2017. "Veterinarian" and "Chamber of Veterinary Surgeons" were used as search items. Homepages of small animal medicine were included. They were surveyed for modes of complementary and naturopathic treatments and corresponding qualifications of the offering veterinarian. Data were collected and processed using Excel 2013 Version 15.0. Afterward, a descriptive data analysis was performed. RESULTS: 60.7% (n = 657) of homepages showed contents of veterinary naturopathy and complementary medicine. The highest percentage was found in the Chamber of Veterinary Surgeons of Saarland (91.7%, n = 11 out of 12). Homeopathy was cited most frequently (58%, n = 381). Out of all homepages with relevant content, 31.4% (n = 206) gave information about user qualifications, with continuous education programs named most frequently (52.9%, n = 109). CONCLUSION: The given data illustrate the high number of German veterinary homepages with contents of veterinary naturopathy and complementary medicine, corresponding to actual data of a high usage in veterinary and human medicine. Therefore, further scientific research in this field seems reasonable. Modes of treatment and qualifications are highly diverse and despite of controversial public discussions, homeopathy was the most frequently cited treatment modality on German veterinary homepages.

The impact of the medical speciality in primary health-care problem solving in Belo Horizonte, Brazil: homeopaths versus family doctors: a preliminary quantitative study.

INTRODUCTION: This research project examined influence of the doctors' speciality on primary health care (PHC) problem solving in Belo Horizonte (BH) Brazil, comparing homeopathic with family health doctors (FH), from the management's and the patients' viewpoint. In BH, both FH and homeopathic doctors work in PHC. The index of resolvability (IR) is used to compare resolution of problems by doctors. METHODS: The present research compared IR, using official data from the Secretariat of Health and test requests made by the doctors and 482 structured interviews with patients. A total of 217,963 consultations by 14 homeopaths and 67 FH doctors between 1 July 2006 and 30 June 2007 were analysed. RESULTS: The results show significant differences greater problem resolution by homeopaths compared to FH doctors. CONCLUSION: In BH, the medical speciality, homeopathy or FH, has an impact on problem solving, both from the managers' and the patients' point of view. Homeopaths request fewer tests and have better IR compared with FH doctors. Specialisation in homeopathy is an independent positive factor in problem solving at PHC level in BH, Brazil.

[Scientific medicine and care relationship: From the therapeutic alliance to the therapeutic effect of the alliance]. / Médecine scientifique et relation de soin : de l'alliance thérapeutique à l'effet thérapeutique de l'alliance.

The new paradigm of precision medicine in oncology questions today the respective place of evidence-based medicine and doctor-patient relationship. Based on the results of a randomized study comparing the efficacy of a homeopathic molecule in the prevention of nausea and vomiting induced by chemotherapy in non-metastatic breast cancer, this article extends and develops the discussion of maintaining an unresolved tension between medical art and medical science, between care and cure. This tension sets a base for the authors of the therapeutic alliance in medicine, defined as a dialectic constantly adjourned between the alliance of the doctor with the patient and his therapy, and the therapeutic effect of this alliance. Because if a policy or a public opinion were to promote an exclusively rational medicine deprived of the field of relation to care, or on the contrary a medicine based only on clinical sense and intuition, then respectively the ethics of care and the progress of therapy would be threatened. It is advisable to be aware of erring from the truth, amplified today by social networks, as much due to a tide of scientific positivism, as an excess of the "good caring soul". Taking into account the therapeutic alliance makes it possible to no longer oppose scientific medicine and care relationship.

Sustainability as a challenge to therapeutics - The Hahnemannian and Gandhian approach.

Sustainability, i.e. the goal of maintaining a human-ecosystem equilibrium, is a comprehensive topic and suggestive ideal prompted by many current threats from and to humanity, such as climate change, environmental pollution, fatal drug reactions in modern medicine, and the like. Today, sustainable concepts are desperately needed, also in terms of medical treatment. Homeopathy offers an approach of rational and yet innocuous therapeutics, methodically not being reliant on prior animal testing and mass production of drugs, avoiding contamination of soil, air, or water, and toxic side-effects. It is based on a concept of specifically empowering the life-force of the patient to rid itself from pathogenic influences. Homeopathy, as outlined by its founder Samuel Hahnemann, may indeed be understood in a broader sense than just medicinal, and applied in a pedagogical, psychological, and political context as well. A similar methodically related approach may be found in Mahatma Gandhi's strategy of Satyagraha (holding onto truth) which also aims to specifically prompt and compel people to renounce their vices in a sustainable way. Both ways of healing in a moral sense, however, rest on premises whose plausibility has increasingly been questioned in the recent past. Thus, the waning appreciation of Hahnemann's and Gandhi's mindset is mirroring unsettling changes in the world's socioeconomic constitution rather than indicating its putative ineptitude to achieve sustainability on a global scale.

Doctors of Plural Medicine, Knowledge Transmission, and Family Space in India.

The transmission of traditional medical knowledge - either institutionally or through established lineages - is assumed to involve one single tradition or another. In India however, families of doctors often engage with multiple traditions, including Ayurveda, Unani, homeopathy, yoga, and biomedicine. Parents, children, siblings and spouses trained in different medical systems occasionally share knowledge and clinical space, producing versatile therapies. By exploring such cases, I challenge studies focused on single traditions and propose to examine "family space" as the physical and relational proximity that enables kin doctors to experiment with plural therapies while negotiating legitimacy and authority within the changing institution of the Indian family.

Câncer materno: a compreensão da criança e suas representações / Maternal cancer: the child's understanding and its representations / Cáncer materno: comprensión del niño y sus representaciones

O câncer é uma doença crônico-degenerativa, que tem como uma de suas principais características a capacidade de invadir tecidos e órgãos do corpo, favorecendo o crescimento desordenado de células. É uma doença que impacta fortemente a pessoa enferma e todos à sua volta, incluindo sua família e seus amigos. A partir desse cenário, este trabalho visou compreender a visão da criança e o impacto emocional sofrido diante do diagnóstico de câncer da mãe. Buscou-se avaliar, a partir de ferramentas lúdicas e do desenho-estória, o entendimento da criança em relação ao processo de adoecimento materno, tomando como base o referencial psicanalítico para reconhecer como ela lidou com a situação. Participaram desta pesquisa uma mulher de 39 anos com diagnóstico de câncer em remissão e seu filho de 9 anos. Os resultados demonstraram que o adoecimento materno causou impactos emocionais significativos e assustadores para o infante, gerando fantasias irreais relacionadas ao câncer e a si próprio. Dessa forma, considera-se de fundamental importância o cuidado estendido aos familiares do indivíduo doente, a fim de que se tenha um olhar a todos que sofrem diante desse contexto.(AU)

Cancer is a chronic-degenerative disease that has as one of its main characteristics the ability to invade tissues and organs of the body, favoring the disordered cell growth. It is a disease that strongly impacts the sick person and everyone around them, including their family and friends. Based on this scenario, this work aimed to understand the child's view and the emotional impact suffered in the face of the mother's cancer diagnosis. It sought to evaluate, with ludic tools and drawing history, the child's understanding about the mother's illness process, based on the psychoanalytic framework to recognize how they deal with the situation. A 39-year-old woman diagnosed with cancer, in remission, and her 9-year-old son participated in this research. The results showed that the maternal illness caused significant and frightening emotional impacts for the infant, creating unrealistic fantasies related to cancer and to himself. Thus, the care extended to the sick individual's family and to the relatives is considered of fundamental importance, to give a complete care for all those who suffer in this context.(AU)

El cáncer es una enfermedad crónico-degenerativa, que tiene como una de sus principales características la capacidad de invadir tejidos y órganos, favoreciendo un crecimiento desordenado de las células. Enfermedades como esta impactan fuertemente a la persona que está enferma y a todos los que la rodean, incluidos familiares y amigos. Considerando esta situación, este estudio tuvo como objetivo comprender la percepción de un niño y el impacto emocional que sufrió ante el diagnóstico del cáncer vivido por su madre. Se pretendió evaluar, utilizando herramientas lúdicas y de dibujo-cuento, la comprensión del niño al proceso de enfermedad materna, buscando reconocer cómo el niño manejó este proceso a partir del referencial teórico psicoanalítico. En esta investigación participaron una mujer de 39 años diagnosticada de cáncer en remisión y su hijo de 9 años. Los resultados mostraron que los impactos emocionales de la enfermedad materna fueron significativos y aterradores para el infante, generando fantasías irreales relacionadas con el cáncer y él mismo. De esta forma, el cuidado extendido a la familia del individuo que está enfrentando esta enfermedad es importante para promover una atención integral a quienes la padecen en este contexto.(AU)

O mundo privado na UTI: análise da internação de pacientes oncológicos / The private world in the ICU: analysis of the hospitalization of oncology patientes / El mundo privado en la UCI: análisis de la hospitalización de pacientes oncológicos

O presente estudo buscou investigar a percepção que pacientes adultos de uma unidade de terapia intensiva (UTI) oncológica têm acerca da experiência de internação nesse setor. Trata-se de uma pesquisa de abordagem qualitativa e de compreensão. Sete pacientes de um hospital de câncer na região Sul do país foram pesquisados. Eles responderam a uma entrevista semiestruturada, a qual foi gravada e posteriormente transcrita, o que possibilitou o acesso às concepções prévias desses sujeitos acerca da UTI, aspectos psicológicos presentes durante a internação e concepções posteriores à experiência de internamento na unidade. Tais informações foram interpretadas por meio da análise de conteúdo. A partir dos resultados, foi possível verificar que a experiência de internação em contextos de terapia intensiva pode ser afetada, favorável ou desfavoravelmente, pelo conjunto de regras que o paciente traz consigo acerca do que é a UTI. Além disso, foi possível compreender também que os estímulos aversivos existentes nesse ambiente podem ser atenuados pela presença da família e por uma relação acolhedora e sensível com a equipe de saúde, favorecendo, assim, o repertório de enfrentamento do paciente frente a esse momento crítico de saúde.(AU)

This study aims to investigate the perception of adult patients in an oncology intensive care unit (ICU) regarding the experience of hospitalization in this sector. This is a research with a qualitative approach and understanding. Seven patients from a cancer hospital in the southern region of the country were surveyed. They answered a semi-structured interview, which was recorded and later transcribed, on the subjects' previous conceptions about the ICU, psychological aspects present during hospitalization, and conceptions subsequent to the hospitalization experience in the Unit. Such information was interpreted through content analysis. From the results, it was possible to verify that the experience of hospitalization in intensive care contexts can be affected, favorably or unfavorably, by the set of rules that the patient brings with them about what the ICU is. In addition, it was also possible to understand that the aversive stimulus existing in this environment can be attenuated by the presence of the family and by a welcoming and sensitive relationship with the health team, thus favoring the patient's coping repertoire when facing a critical moment of health.(AU)

Este estudio pretendió investigar la percepción que tienen los pacientes adultos sobre la experiencia de hospitalización en una Unidad de Cuidados Intensivos (UCI) de oncología. Se trata de una investigación con enfoque cualitativo y de comprensión. Participaron siete pacientes de un hospital oncológico en la región Sur de Brasil. Se aplicó una entrevista semiestructurada, que fue grabada y, posteriormente, transcrita, lo que permitió acceder a las concepciones previas de los sujetos sobre la UCI, los aspectos psicológicos presentes durante la hospitalización y las concepciones posteriores a la experiencia de internación en la Unidad. Dicha información se interpretó mediante análisis de contenido. A partir de los resultados, fue posible constatar que la experiencia de hospitalización en cuidados intensivos puede ser afectada favorable o desfavorablemente por el conjunto de normas que el paciente trae consigo sobre qué es la UTI. Además, se constató que los estímulos adversos existentes en este ambiente pueden mitigarse mediante la presencia de la familia y la relación acogedora y sensible con el equipo de salud, lo que favorece así el repertorio de afrontamiento del paciente ante este momento crítico de salud.(AU)

Limitations of Western Medicine and Models of Integration Between Medical Systems.

This article analyzes two major limitations of Western medicine: maturity and incompleteness. From this viewpoint, Western medicine is considered an incomplete system for the explanation of living matter. Therefore, through appropriate integration with other medical systems, in particular nonconventional approaches, its knowledge base and interpretations may be widened. This article presents possible models of integration of Western medicine with homeopathy, the latter being viewed as representative of all complementary and alternative medicine. To compare the two, a medical system was classified into three levels through which it is possible to distinguish between different medical systems: epistemological (first level), theoretical (second level), and operational (third level). These levels are based on the characterization of any medical system according to, respectively, a reference paradigm, a theory on the functioning of living matter, and clinical practice. The three levels are consistent and closely consequential in the sense that from epistemology derives theory, and from theory derives clinical practice. Within operational integration, four models were identified: contemporary, alternative, sequential, and opportunistic. Theoretical integration involves an explanation of living systems covering simultaneously the molecular and physical mechanisms of functioning living matter. Epistemological integration provides a more thorough and comprehensive explanation of the epistemic concepts of indeterminism, holism, and vitalism to complement the reductionist approach of Western medicine; concepts much discussed by Western medicine while lacking the epistemologic basis for their emplacement. Epistemologic integration could be reached with or without a true paradigm shift and, in the latter, through a model of fusion or subsumption.

The frontier of modern Western medicine in Nepal.

Using the concepts frontier and interface the introduction and spreading of modern Western medicine in Nepal and its relations to other medical systems are described and analyzed. Medical systems do not prevail in the same degree in all places; we may call the geographic areas of concentration the core areas or center(s) of medical systems and the remaining areas their periphery. The frontier of a medical system is defined as that part of the periphery where the presence of the system is increasing. The place of the frontier, its width and the forms in which a medical system appears at its frontier are determined by both internal dynamics and contextual factors. In non-socialist countries like Nepal the dynamics of modern Western medicine are characterized by three tendencies: centralization, expansiveness and a commercial and capitalist character. Some important contextual factors which have been shaping the frontier in Nepal are: migration, including tourism, labor-migration and trade; the role of foreign aid and geographical conditions. The situation at the frontier has an important influence on the nature of the interface between modern Western medicine and other medical systems. In the article Faith-healing, Ayurvedic medicine, Homeopathy and Tibetan medicine are described briefly and the interface between them and modern Western medicine is looked into.

Is the emergency readmission rate a valid outcome indicator?

OBJECTIVES: The principal aim was to determine whether the emergency readmission rate varies between medical specialties, and to identify whether differences in emergency readmission rates between hospital trusts can be reduced by standardising for specialty. Possible factors influencing emergency readmission were also investigated, including frequency of previous admission and cause of readmission. DESIGN: Emergency readmission rates were obtained from the Scottish Morbidity Record scheme (SMR1) using record linkage, standardised for age and sex. Rates throughout Scotland were analysed by specialty, and rates for general medicine compared among teaching hospital trusts. Cause of emergency readmission was determined from hospital records in a random sample (177 patients). SETTING: Medical specialties throughout Scotland. SUBJECTS: All patients readmitted as an emergency within 28 days of discharge (October 1990 to September 1994). RESULTS: Emergency readmissions varied markedly between medical specialties, with highest rates in nephrology (24.2%, 95% CI 23.5 to 24.8) and haematology (20.4%, 95% CI 19.9 to 20.9), and the lowest in homeopathy (2.2%, 95% CI 1.6 to 2.7) and metabolic diseases (3.5%, 95% CI 2.4 to 4.5). The largest number of emergency readmissions was in general medicine, accounting for 63% of the total. Restricting emergency readmission rates to general medicine significantly altered previous rates. In the year preceding the emergency readmission, 59% of all patients had been admitted to hospital at least once, and most emergency readmissions (73.3%) resulted from a chronic underlying condition. CONCLUSIONS: Significant variations in emergency readmission rates occurred between medical specialties, suggesting that differences between hospital trusts are influenced by differences in specialties and thus case mix. The majority of emergency readmissions occurred in patients with an underlying chronic condition, and many had a history of multiple previous hospital admissions. The emergency readmission rate is therefore unlikely to be a valid outcome indicator reflecting quality of care until routine data are available for standardisation by case mix.

Referrals for alternative therapies.

BACKGROUND: The purpose of this study was to examine how allopathic physicians participate in the decision to refer patients for alternative therapies. METHODS: A pretested, self-administered, structured questionnaire was distributed simultaneously to all area physicians at community locations in Washington State, New Mexico, and southern Israel. The primary outcome measures were monthly and yearly rates of referral to alternative therapies. RESULTS: More than 60% of all physicians made referrals to alternative providers at least once in the preceding year and 38% in the preceding month. Referrals were generally based on patient requests, synergy between the alternative therapy and the patients' cultural beliefs, failure of conventional treatment, and the belief that patients have "nonorganic" or "psychological" disease. There was no relationship between the rate of referral and the referring physician's level of knowledge about, beliefs about the effectiveness of, or familiarity with alternative therapies. CONCLUSIONS: Primary care physicians are more likely than other medical specialists to be knowledgeable about, personally subscribe to, and refer patients for alternative therapies. Physicians who use alternative techniques for themselves and their families or who adopt complementary therapies into their practices have higher rates of referrals. Referral rates and patterns were similar between sites despite considerable cross-cultural and health system differences. Given the high rate of referral and the absence of an apparent internal logic for such recommendations, guidelines and physician education may be advisable.
