Who’s a Quack?

Are there any characteristics by which we can reliably identify and distinguish quackery from genuine medicine? A commonly offered criterion for the distinction between medicine and quackery is science: genuine medicine is scientific; quackery is non-scientific. But it proves to be the case that at the boundary of science and non-science, there is an entanglement of considerations. Two cases are considered: that of homoeopathy and that of the Quantum Booster. In the first case, the degree to which reported phenomena that question established theory should be doubted arises; in the second case, the status of pleomorphism as a scientifically plausible doctrine is discussed. The application of the criterion of being scientific to these cases reveals something of the nature and density of the entanglement.     

Bioethics for clinicians: 9. Involving children in medical decisions

Medical decisions involving children raise particular ethical issues for physicians and other members of the health care team. Although parents and physicians have traditionally made most medical decisions on behalf of children, the developing autonomy of children is increasingly being recognized in medical decision-making. This poses a challenge for physicians, who must work with the child''s family and with other health care practitioners to determine the child''s role in decision-making. A family-centred approach respects the complex nature of parent-child relationships, the dependence and vulnerability of the child and the child''s developing capacity for decision-making.     

Medical professionalism: crossing a generational divide

A comprehensive discussion of professionalism in medicine must include its impact on successive generations of physicians. Fifty years ago, doctors acting professionally emphasized medicine as a calling and an ability to act as the authority for patients in crisis at home and in hospitals. Therapeutic options were limited relative to the modern era, and the laying on of hands was practiced as science and art. Today, doctors balance increasing demands on time and efficiency with the sense of primacy of patient care. Technological innovation and patients' increasing access to medical knowledge through varying media of inconsistent quality challenge physicians in novel ways. Fifty years in the future, doctors will have access to vast amounts of information through a multitude of noninvasive diagnostics. Progressively more personalized medicine should inspire doctors to become even more adept at communicating effectively with patients. Professionalism in medicine throughout these generations embodies similar fundamental behaviors, such as demonstrating compassion, respect, and humility; adhering to high ethical and moral standards; subordinating personal interest to that of others; and reflecting on actions and decisions. Despite the dynamic nature of the profession itself, the omnipresent need for such traits will define medical professionalism for decades to come.     

The Flexner Report--100 years later

The Flexner Report of 1910 transformed the nature and process of medical education in America with a resulting elimination of proprietary schools and the establishment of the biomedical model as the gold standard of medical training. This transformation occurred in the aftermath of the report, which embraced scientific knowledge and its advancement as the defining ethos of a modern physician. Such an orientation had its origins in the enchantment with German medical education that was spurred by the exposure of American educators and physicians at the turn of the century to the university medical schools of Europe. American medicine profited immeasurably from the scientific advances that this system allowed, but the hyper-rational system of German science created an imbalance in the art and science of medicine. A catching-up is under way to realign the professional commitment of the physician with a revision of medical education to achieve that purpose.     

MEDICAL CARE AND PUBLIC HEALTH SERVICES

Medical care applies to the individual, and public health to the community. One is the concentrated application of diagnosis and treatment for the life, the comfort of a patient, and includes guidance in health as for motherhood, infancy, childhood and old age.Public health services, provided by the community through its local government and the local department of health, are concerned with the prevention of diseases of all kinds. Some are controlled by sanitary authority, but the majority of preventable diseases are dealt with by public health education.It is not the function of the health department to treat the sick. The family physicians, the hospitals and dispensaries provide for medical care. Medical care of the sick and public health protection are two parallel activities to make use of medical science, one for treatment, the other for prevention of disease.     

CMA membership survey: opinions on issues facing the medical profession

A sample survey of Canadian Medical Association (CMA) members, conducted in early summer 1985 and designed to provide information to help guide the association''s activities and policies, shows that most Canadian physicians support involvement in political activities both by CMA and by indivudual physicians. A majority wishes to maintain the concept of extra/balance billing, to pursue the position that the health care system is underfunded and favours medicare premiums and hospital user fees as the preferred methods for increasing revenue.Most respondents believe that the number of doctors in Canada is about right but would prefer any reduction to be achieved by cutting medical school admissions or reducing postgraduate training positions open to graduates of foreign medical schools.Most of those members who know of CMA policies on a number of health care issues agree with them and also find them useful, but a significant proportion are not aware of their content.There is support for compulsory payment of dues by all licensed physicians to both their provincial medical association and CMA. A majority would like more information on pharmaceutical products and additional membership surveys.     

Historical reflections on the changing concepts of disease.

One of the concerns of the Committee on the Role of Medicine in Society of the California Medical Association is the apparent “attitude gap” between medical students and physicians already established in practice. In November 1967, the first of a series of meetings took place between Committee members and senior students from each California medical school. Discussion ranged from curriculum planning to individual and organizational politics, and revealed differences of opinion between students and physicians on such issues as Medicare and the financing of health care for the nation.These discussions suggested to members of the Committee that several clearly defined subject areas were worthy of further investigation. It was decided, therefore, that a questionnaire be sent to medical students and residents, with the goal of gaining a better understanding of the nature and extent of such differences of opinion. Some of the highlights of the findings of this survey are discussed in this Socio-Economic Report.     

Physiology,Hygiene and the Entry of Women to the Medical Profession in Edinburgh c. 1869–c. 1900

Academic physiology, as it was taught by John Hughes Bennett during the 1870s, involved an understanding of the functions of the human body and the physical laws which governed those functions. This knowledge was perceived to be directly relevant and applicable to clinical practice in terms of maintaining bodily hygiene and human health. The first generation of medical women received their physiological education at Edinburgh University under Bennett, who emphasised the importance of physiology for women due to its relevance for the hygienic needs of the family and of society. With the development of laboratory-based science as a distinct aspect of medical education during the later nineteenth century, however, so the direct application of physiology to clinical practice diminished. The understanding of physiology as hygiene was marginalised by the new orthodoxy of scientific medicine. This shift in the physiological paradigm enabled medical women to stake out a specific field of interest within medicine which was omitted from the new definition of physiology as pure medical science: hygiene and preventive medicine. Women physicians were able to take advantage of the shift towards science as the basis of medical theory and practice to define their own specific role within the profession.     

Medical decision making and medical education: challenges and opportunities

The Flexner Report highlighted the importance of teaching medical students to reason about uncertainty. The science of medical decision making seeks to explain how medical judgments and decisions ought ideally to be made, how they are actually made in practice, and how they can be improved, given the constraints of medical practice. The field considers both clinical decisions by or for individual patients and societal decisions designed to benefit the public. Despite the relevance of decision making to medical practice, it currently receives little formal attention in the U.S. medical school curriculum. This article suggests three roles for medical decision making in medical education. First, basic decision science would be a valuable prerequisite to medical training. Second, several decision-related competencies would be important outcomes of medical education; these include the physician's own decision skills, the ability to guide patients in shared decisions, and knowledge of health policy decisions at the societal level. Finally, decision making could serve as a unifying principle in the design of the medical curriculum, integrating other curricular content around the need to create physicians who are competent and caring decision makers.     

A Statewide Approach to Health Care Personnel Maldistribution—The California Area Health Education Center System

An Area Health Education Center (AHEC) system has been established in California to address the maldistribution of physicians and other health care professionals. The AHEC program uses educational incentives to recruit and retain health care personnel in underserved areas by linking the academic resources of university health science centers with local educational and clinical facilities. The medical schools, working in partnership with urban or rural AHECs throughout the state, are implementing educational programs to attract trainees and licensed professionals to work in underserved communities. The California AHEC project entered its fifth year in October of 1983 with the participation of all eight medical schools and the Charles Drew Postgraduate School of Medicine, 35 other health professions schools, 17 independent AHECs and more than 400 clinical training sites. Educational programs are reaching more than 22,000 students and practicing health professionals throughout California. We review the current status of the California AHEC system and use the AHEC programs at Loma Linda University to illustrate the effect this intervention is having.     

Pondering the future.

Despite growing tensions as the Canadian health care system evolves, the system will survive over the next decade and strengthen its societal objectives, sometimes dragging physicians along. With the shift of the intellectual centre away from the universities, research and researchers will find funding security but career insecurity in the private sector. The independent investigator will become rare as "big science" becomes the norm, and basic science departments will have a decade of confusion as they struggle for a new place in the renewed medical schools. The move toward problem-based, community-oriented medical education will be completed, clinical faculty will become salaried and the smaller numbers of graduates will be more controlled in their practices. Medicine as a profession will adopt a renewed philosophical framework and will broaden in its scope to the benefit of Canadians.     

Naturopathy: a critical appraisal

"Naturopathic medicine" is a recent manifestation of the field of naturopathy, a 19th-century health movement espousing "the healing power of nature." "Naturopathic physicians" now claim to be primary care physicians proficient in the practice of both "conventional" and "natural" medicine. Their training, however, amounts to a small fraction of that of medical doctors who practice primary care. An examination of their literature, moreover, reveals that it is replete with pseudoscientific, ineffective, unethical, and potentially dangerous practices. Despite this, naturopaths have achieved legal and political recognition, including licensure in 13 states and appointments to the US Medicare Coverage Advisory Committee. This dichotomy can be explained in part by erroneous representations of naturopathy offered by academic medical centers and popular medical Web sites.     

Update and perspectives on congenital disorders of glycosylation.

Defects in nine genes of the N-linked glycosylation pathway cause congenital disorders of glycosylation (CDGs) and serious medical consequences. Although glycobiology is seldom featured in a general medical education, an increasing number of physicians are becoming acquainted with the field because it directly impacts patient diagnosis and care. Medical practice and attitudes will change in the postgenomic era, and glycobiology has an opportunity to be a cornerstone of part of that new perspective. This review of recent developments in the CDG field describes the biochemical and molecular basis of these disorders, describes successful experimental approaches, and points out a few perspectives on current problems. The broad, multisystemic presentations of these patients emphasize that glycobiology is very much a general medical science, cutting across many traditional medical specialties. The glycobiology community is well poised to provide novel perspectives for the dedicated clinicians treating both well-known and emerging human diseases.     

Physicians and the pharmaceutical industry (update 1994). Canadian Medical Association.

The history of health care delivery in Canada has been marked by close collaboration between physicians and the pharmaceutical and health supply industries, this collaboration extending to research as well as to education. Since medicine is a self-governing profession physicians have a responsibility to ensure that their participation in such collaborative efforts is in keeping with their duties toward their patients and society. The following guidelines have been developed by the CMA to assist physicians in determining when a relationship with industry is appropriate. Although directed primarily to individual physicians, including residents and interns as well as medical students, the guidelines also govern the relationships between industry and medical associations. These guidelines focus on the pharmaceutical companies; however, the CMA considers that the same principles apply to the relationship between its members and manufacturers of medical devices, infant formulas and similar products, and health care products and service suppliers in general. These guidelines reflect a national consensus and are meant to serve as an educational resource for physicians throughout Canada.     

Computers a cornerstone of evidence-based care,conference told.

Computers are poised to become key players in the delivery of health care, but are physicians ready for them? A recent conference on medical communication in the electronic era examined the potential of computers to assist in diagnosis, provide continuing medical education, disseminate evidence and research findings, and simplify practice management. However, delegates were told that even though many medical practices are computerized, it is often staff members and not physicians who use the technology. For computers to gain wider acceptance for medical purposes, physicians need to be made comfortable with their use at an early stage of training.     

Community medicine for clinicians in Canada: a recommendation for postgraduate training.

A large gap presently exists between the predominantly biologic expertise of the medical profession and the complex mixture of biologic, behavioural and epidemiologic components of health problems today. Furthermore, the development of community medicine in Canada has been relatively separate from that of the clinical disciplines. To enable clinicians to acquire the knowledge and skills to manage these health problems, much more community-oriented research, applied behavioural science and clinical epidemiology is needed within the clinical sector of medicine. I have proposed a definition of clinical community medicine and presented a strategy for training clinicians in community medicine skills that calls for administrators of clinical postgraduate programs to develop training in clinical community medicine. Residency programs in community medicine cannot be expected to provide such training given their nonclinical priorities, which focus mainly on the training of public health physicians.     

人文素质教育与医学免疫学专业教育的整合

当前,人们的健康观念和生活方式发生了改变,对医疗卫生服务的需要和期望也发生了变化。然而,医学教育长期以来过分注重医学生的专业知识教育而忽视了人文素质教育,这使得医学生缺乏爱伤观念,对待病人冷漠、和不负责任,功利心较重,缺少奉献精神,从而加剧了医患关系紧张。因此,把医学生人文教育渗透到医学生专业学习的各个过程,使人文素质教育与医学专业教育完美的整合,才能培养出同时具有精湛医术和人文智慧、德才兼备的医生。医学免疫学是生命科学的前沿学科,是联系基础医学和临床医学的桥梁学科之一,也是医学本科生的一门重要的主干课程,其理论和实验技术发展迅猛。本文从医学免疫学专业理论课、实验课、考核等不同环节探讨了人文素质教育和医学免疫学专业教育的整合,进一步地寻找医学免疫学教学中人文素质教育的有效途径,为医学生的人文素质的全面提高提供有益的支持。     

MEETING COMMUNITY HEALTH NEEDS—The Combined Role of the Physician,Health Department and Hospital

Social and economic changes—the lengthening life span, the shift of population from rural to urban areas, the growth of industry and other factors—have brought about radical changes in the nation''s health needs. Our greatest health problem today is chronic illness. To cope with these problems public health, medical care and hospital services, which are at present geared primarily for acute illness, must be revised.Immediate and specific steps which physicians, health departments and hospitals can take to accomplish this are to define the problem and to initiate studies in several areas: To determine the incidence and prevalence of disease, injuries and impairments; the nature, degree and duration of resulting disability; and the type of care received.The basic approach to chronic illness is prevention. To accomplish this, more emphasis needs to be placed upon health education. Good health cannot be forced upon the public, but educated and enlightened citizens can and do solve their own health problems and those of their families and communities.Due to the complex nature of today''s health problems, they must be approached jointly by physicians, local health services, hospitals and the public. The efforts of those groups must be coordinated and aimed, directly and indirectly, at preventing disease and disability.     

Competencies in premedical and medical education: the AAMC-HHMI report

One hundred years ago, Flexner emphasized the importance of science in medicine and medical education. Over the subsequent years, science education in the premedical and medical curricula has changed little, in spite of the vast changes in the biomedical sciences. The National Research Council, in their report Bio 2010, noted that the premedical curriculum caused many students to lose interest in medicine and in the biological sciences in general. Many medical students and physicians have come to view the premedical curriculum as of limited relevance to medicine and designed more as a screening mechanism for medical school admission. To address this, the Association of American Medical Colleges and the Howard Hughes Medical Institute formed a committee to evaluate the premedical and medical school science curricula. The committee made a number of recommendations that are summarized in this essay. Most important were that competencies replace course requirements and that the physical sciences and mathematics be better integrated with the biological sciences and medicine. The goal is that all physicians possess a strong scientific knowledge base and come to appreciate the importance of this to the practice of medicine. While science education needs to evolve, Flexner's vision is as relevant today as it was 100 years ago.
