[Placebo and the relationship between doctors and patients. Overview]. / Placeboaspekte der Arzt-Patienten-Beziehung. Übersicht.

In medicine, placebos are used both in scientific studies and for practical therapeutic purposes. In evidence-based medicine, the efficacy of treatment may be determined as the difference between the effects of the verum (the active study drug) and the placebo, the latter being a substance lacking specific action on the disease under consideration. However, the improvements in patients' conditions under placebo treatment may be substantial and comparable to those with verum. Genuine placebos predominate in clinical studies, while pseudoplacebos prevail in practical therapy. The term pseudoplacebo can also be applied to many procedures in complementary medicine, including homeopathic medicine (Büchel et al., Placebo in der Medizin, 2011). The comprehensive definition of placebo, as used in a report by the German Medical Association (Büchel et al., Placebo in der Medizin, 2011), states that a placebo effect may occur even when treating with verum. The placebo effect is modulated by the context of the treatment, by the expectations of the patients and the doctors, and by the success of the relationship between doctors and patients. A number of unspecific effects, e.g., spontaneous alleviation, statistical effects, variance with time, methodological errors, in addition to the placebo effect make up the total response that is called"placebo reaction." A complete list of the effectiveness of placebo for all important diseases is still lacking. Further, it is not possible to predict which patients will respond to placebo. Which characteristics of doctors are important (competence, empathy, communicative ability and partnership, trust) in order to achieve a placebo effect, particularly in addition to the verum effect measures of evidence-based medicine? Are there doctors who are better in this than others? Could the nocebo effect weaken the efficacy of treatment in evidence-based medicine? Since a placebo effect may occur in almost any standard therapy, information about placebos should be provided during medical education and continuing medical education (CME). The use of placebo in clinical studies is ethically justified and lawful in consenting patients if there is no other effective treatment available with which the test substance could be compared. For daily practical therapeutic purposes, placebos may be ethically acceptable and lawful if there is no effective therapy available, if the complaints are minor, if the patient expressly wishes treatment, and if there is a reasonable likelihood of success. However, an explanation of the expected benefits and risks must be provided to the patients. At present, there are two explanatory theories for the mechanism of action of placebo, namely, the associative and the mentalistic explanation (Büchel et al., Placebo in der Medizin, 2011). Interestingly, effects of placebo and of verum can be localized in the brain by physiological and anatomical techniques. With many open questions remaining, research on placebo is currently very active. These aspect and neurobiological findings in particular may facilitate for "scientifically" educated doctors to accept that ineffective materials, i.e., placebos, are in fact effective.

How do parents of child patients compare consultations with homeopaths and physicians? A qualitative study.

OBJECTIVE: How do parents of child patients experience and compare consultations with homeopaths and physicians, and how do they describe an ideal consultation. METHODS: A qualitative study with interviews of parents to 16 children who had consulted both a homeopaths and a physicians. RESULTS: Comparing consultations with physicians and homeopaths, the parents experienced the homeopathic consultations to a greater extent to have a whole person approach, also described as a core factor in an ideal consultation. This approach included exhaustive questioning, longer consultations, more interaction with the child and looking for the underlying cause. CONCLUSION: The parents in this study perceived that the homeopathic consultation had a whole person approach while consultations with most physicians focused on the symptoms. The homeopathic consultation was said to be more in line with what the parents perceived to be an ideal consultation for their children than consultation with physicians. PRACTICE IMPLICATIONS: Treatment philosophy and the aim of the consultation are likely to play a larger part than the technical aspects in determining the form and content of a consultation. Training in communication could benefit from including discussions on how the practitioner's treatment philosophy influences the consultation behavior.

Classification of complementary and alternative medical practices: Family physicians' ratings of effectiveness.

ABSTRACTOBJECTIVETo develop a classification of complementary and alternative medicine (CAM) practices widely available in Canada based on physicians' effectiveness ratings of the therapies.DESIGNA self-administered postal questionnaire asking family physicians to rate their "belief in the degree of therapeutic effectiveness" of 15 CAM therapies.SETTINGProvince of Alberta.PARTICIPANTSA total of 875 family physicians.MAIN OUTCOME MEASURESDescriptive statistics of physicians' awareness of and effectiveness ratings for each of the therapies; factor analysis was applied to the ratings of the 15 therapies in order to explore whether or not the data support the proposed classification of CAM practices into categories of accepted and rejected.RESULTSPhysicians believed that acupuncture, massage therapy, chiropractic care, relaxation therapy, biofeedback, and spiritual or religious healing were effective when used in conjunction with biomedicine to treat chronic or psychosomatic indications. Physicians attributed little effectiveness to homeopathy or naturopathy, Feldenkrais or Alexander technique, Rolfing, herbal medicine, traditional Chinese medicine, and reflexology. The factor analysis revealed an underlying dimensionality to physicians' effectiveness ratings of the CAM therapies that supports the classification of these practices as either accepted or rejected.CONCLUSIONThis study provides Canadian family physicians with information concerning which CAM therapies are generally accepted by their peers as effective and which are not.

The Cavendish Centre for integrated cancer care: assessment of patients' needs and responses.

The use of complementary therapies in combination with conventional medicine is increasing. In cancer care, as at the Cavendish Centre for Cancer Care in Sheffield, the range of therapies offered can include aromatherapy, massage, reflexology, shiatsu, acupuncture, homeopathy, counselling, visualization, hypnotherapy, relaxation, healing and art therapy. Before offering any therapy careful assessment of patients' needs is important as patients seeking complementary therapies may present with unrealistic hopes and expectations of benefit. There are wide variations in provision of services offering complementary cancer care throughout the United Kingdom but few offer a comprehensive assessment which is used as a baseline for both planning treatment and evaluating its outcome and which is conducted by a trained and objective practitioner who has no investment in any specific therapy. We describe the model of care developed at the Cavendish Centre with particular emphasis on the assessment process. Our model of assessment provides an opportunity for patients to tell their story, make sense of the illness experience, construct meaning from it and set realistic expectations for the chosen intervention. It also offers patients involvement and choice in decisions about their care. In addition we present evaluative data from a case series of 157 patients, 138 of whom (88%) reported improvement in their main concern on MYMOP (Measure Your Medical Outcome Profile).

Medicine at the fringes.

Until the new Act is in operation, and assuming it has strong and clear sections covering competence, the Medical Council of New Zealand is left with the need to manage unorthodoxy as a form of misconduct unless there is a mental health problem. Charges of misconduct unless there is a mental health problem. Charges of misconduct may arise of there is: harm to patients inadequate information and consent including false representation of the theoretical base of diagnostic method or management, or the training of the doctor, short cuts in the standard methods of diagnosis with the use of unproven and unrecognised methods, treatment programmes that are inappropriate, unjustified, unproven or unsupported by a substantial body of opinion, or that omit consideration if orthodox methods. exploitation in terms of securing patients, financial gain and inadequate aftercare.

Alternative medicine and the family physician.

The seven categories of alternative medicine, as established by the National Institutes of Health Office of Alternative Medicine, are mind-body interventions, bioelectromagnetic therapies, alternative systems of medical practice, manual healing methods, pharmacologic and biologic treatments, herbal medicine, and diet and nutrition. Mind-body approaches have been shown to be effective in a variety of conditions. Acupuncture and homeopathy are alternative systems of medical practice that may be beneficial. Chiropractic manipulation for low back pain and infant message for enhancing growth are two methods of manual healing. While the literature on herbal medicine is vast, most of it focuses on a single approach for a specific condition. Traditional herbalists use a combination of herbs individualized for the specific person. As more and more people turn to alternative therapies, it is important for family physicians to be open to their patients' interest in alternative approaches.

Medicine in the USA: historical vignettes. V. The 'old code' of medical ethics and some problems it had to face.

KIE: Attempts by nineteenth-century American physicians to upgrade the status of the medical profession influenced the development of their code of ethics, as chronicled here. Unlike the case in Great Britain, physicians in the U.S. did not constitute a homogenous class in background and education. To distinguish 'regular' physicians from other practitioners such as homeopaths, medical societies tended to emphasize adherence to 'orthodox medical beliefs' in defining the standards of the profession.^ieng

Advising patients who seek alternative medical therapies.

Alternative medical therapies, such as chiropractic, acupuncture, homeopathy, and herbal remedies, are in great public demand. Some managed care organizations now offer these therapies as an "expanded benefit." Because the safety and efficacy of these practices remain largely unknown, advising patients who use or seek alternative treatments presents a professional challenge. A step-by-step strategy is proposed whereby conventionally trained medical providers and their patients can proactively discuss the use or avoidance of alternative therapies. This strategy involves a formal discussion of patients' preferences and expectations, the maintenance of symptom diaries, and follow-up visits to monitor for potentially harmful situations. In the absence of professional medical and legal guidelines, the proposed management plan emphasizes patient safety, the need for documentation in the patient record, and the importance of shared decision making.

Rheumatologists and their patients who seek alternative care: an agreement to disagree.

Alternative treatment, such as homoeopathy, acupuncture and spiritual healing, are popular among patients with rheumatic diseases. Rheumatologists are therefore likely to be confronted with patients who make use of less orthodox health care. Patients' and rheumatologists' views on the subject and on the rheumatologists' role, however, have not yet been assessed. A questionnaire on alternative medicine was sent to all 101 practising Dutch rheumatologists (response rate: 70%). After the results had been analysed 17 rheumatologists, seven rejecting alternative medicine and ten accepting it, handed out a questionnaire to a sample of their patients: 1466 patient questionnaires were distributed (response rate: 80%). Of the respondents 43% had visited an alternative practitioner at least once for their rheumatism and 26% in the year before the survey was held. Hand healers, homoeopaths and acupuncturists were most often visited. Rheumatologists, on their part, were not too enthusiastic about these visits. Only patients' visits to spa treatment centres were welcomed by a majority of them; visits of their patients to manipulative therapists, acupuncturists and homoeopaths were judged positively by a large minority, whereas other therapies were strongly disapproved. Nevertheless, most patients informed their rheumatologist about their visiting an alternative practitioner. A surprisingly low percentage of these patients noticed that the rheumatologist did not sympathize with it. Although many patients paid a visit to an alternative practitioner because regular care did not really help them, their satisfaction with the alternative treatment turned out to be less than their satisfaction with the rheumatologists' help.(ABSTRACT TRUNCATED AT 250 WORDS)
