Physician social capital and the reported adoption of evidence-based medicine: exploring the role of structural holes

The present study explores the role that professional networks play in the propensity of hospital physicians to adopt and implement evidence-based medicine (EBM) into clinical practice. Using attributional and relational data collected from a sample of 207 physicians in six Italian National Health Service hospitals, social network techniques were used to analyze the structure of the networks representing professional interactions among the surveyed hospital physicians. Ordinal logistic regression was applied to analyze the association between the structural features of physicians' networks and their self-reported propensity to implement EBM into daily practice. Physicians who were highly constrained in their interpersonal networks were less likely to report adopting EBM, suggesting that the cohesion induced by social interactions may hamper, rather than foster, the diffusion of scientific information within professional groups. We discuss the implications of the observed interaction patterns for hospital administrators and policy makers.     

Evidence-based medicine: is it relevant to long-term care?

Internists and family physicians are trained in evidence-based medicine (EBM). The philosophy of incorporating clinical research "evidence" into medical practice is taught at the undergraduate and graduate levels of medical training. Practicing physicians incorporate EBM into their practices in variable degrees depending on their training, comfort level, and the nature of their practices. The evidence-based process has not clearly permeated the practice of long-term care, nor does it indisputably transfer from the office and hospital settings. This article discusses the applicability of EBM to the long-term care setting and some of the barriers to implementation.     

Who contextualises clinical epidemiological evidence? A political analysis of the problem of evidence-based medicine in the layered Dutch healthcare system

We critically examine the discussion on the role of evidence-based medicine (EBM) in healthcare governance. We take the institutionally layered Dutch healthcare system as our case study. Here, different actors are involved in the regulation, provision and financing of healthcare services. Over the last decades, these actors have related to EBM to inform their actor specific roles. At the same time, EBM has increasingly been problematised. To better understand this problematisation, we organised focus groups and interviews. We noticed that particularly EBM’s reductionist epistemology and its uncritical use by ‘professional others’ are considered problematic. However, our analysis also reveals that something else seems to be at stake. In fact, all the actors involved underwrite EBM’s reductionist epistemology and emphasise that evidence should be contextualised. They however do so in different ways and with different contexts in mind. Moreover, the ways in which some actors contextualise evidence has consequences for the ways in which others can do the same. We therefore emphasise that behind EBM’s scientific problematisation lurks a political issue. A dispute over who should contextualise evidence how, in a layered healthcare system with interdependent actors that cater to both individual patients and the public. We urge public administration scholars and policymakers to open-up the political confrontation between healthcare actors and their sometimes irreconcilable, yet evidence-informed perspectives.     

Why is evidence-based medicine so harsh on vaccines? An exploration of the method and its natural biases

Vaccines have been hailed as one of the greatest success stories of public health in the 20th century. The 20th century also produced a call for evidence-based medicine (EBM) with applications inclusive of preventive health. Since then, several major EBM analyses have called into question vaccine practices well-accepted by physicians, public health officials, and even the lay public. For example, while counter to existing studies and policies, EBM analyses have concluded that data are lacking to support influenza vaccination of healthcare workers to prevent flu complications among the elderly. In this review, we examine the criticisms and consider the shortcomings in the field of vaccinology as well as in the methodology of evidence-based medicine.

Barriers facing physicians practicing evidence-based medicine in Saudi Arabia

INTRODUCTION: Tremendous advances in health care have been made through the development of evidence-based medicine (EBM). Studies show that physicians face barriers in practice, preventing the effective use of the best evidence available. Insight into these barriers should pave the way for an action plan to remove them. The aim of this study was to explore the major barriers to the practice of EBM by physicians in primary health care centers (PHCCs) and hospitals. METHOD: This cross-sectional study was conducted on physicians in PHCCs and Ministry of Health hospitals in the Dammam area (Dammam, Alkhobar, and Alqatief) of Saudi Arabia. A sample size of 409 physicians was chosen. Barriers to the practice of EBM and the reasons for not giving patients effective health care were investigated through questionnaires. RESULTS: The response rate was 66. 7%. The main barriers to practicing EBM stated by physicians were the lack of training in EBM (72.9%), facilities (34.4%), and time (29.2%). The least mentioned barriers were the lack of relevant evidence and the negative impact on medical skills (10.4% each). DISCUSSION: Rather than skepticism about the concept, the main barriers to the use of EBM by physicians appeared to be a lack of knowledge and basic skills. Therefore, targeted education in EBM and a system that quickly delivers high-quality evidence are needed. This includes the allocation of an adequate infrastructure and time and the availability of relevant evidence.     

Reforming medical education: A review and synthesis of five critiques of medical practice

For physicians to provide appropriate healthcare at a reasonable cost, health reform may not be enough. This essay discusses the scope of educational reform needed in the U.S. to train tomorrow’s physicians to practice effectively in an increasingly complicated health care arena. We undertook a review and synthesis of five critiques of medical practice in the U.S.: of quality, evidence-based medicine, population medicine, health policy and heuristics. Our findings suggest that physicians are inadequately trained to function in the complex organizational and social systems that characterize modern practice. Successful health care reform in the U.S. will require physicians who are trained not only in bio-medicine, but also in the social sciences. Other developed countries, which have both greater government control of health care and a culture less oriented to individualism, may have less need for specific efforts to train physicians in the social sciences but could still benefit from considering an expanded curriculum. Effective educational reform must address the medical admissions process, academic and intellectual preparation, and professional and clinical training.     

Evidence-based healthcare in practice: A study of clinician resistance,professional de-skilling,and inter-specialty differentiation in oncology

Evidence-based medicine (EBM) is strongly shaping the nature and direction of biomedical practice and organisational culture. Clinicians are now expected to adopt the principles of EBM and evidence-based practice (EBP) whilst also maintaining such things as professional autonomy, clinical judgement and therapeutic integrity. Little sociological work has been done on the implications of EBM in oncology contexts. Drawing on in-depth interviews with 13 oncology consultants and 12 oncology nurses in Australia, in this paper we explore how oncology clinicians utilise and/or critique types of evidence and statistical probabilities; the organisational systematisation of care; and, wider policies of EBM. The results illustrate significant variation in perception of EBM between the oncology sub-specialties examined, and the central role of organisational structures and intra-professional hierarchies in how evidence is viewed and utilised in practice. The interviews also capture the ways in which oncology specialists are negotiating the systematisation of care under the rubric of EBM, and the contradictory effects of professional de-skilling vis-à-vis the reinforcement of biomedical objectivity/power. Finally, we examine the experiences and perceptions of oncology nurses in relation to evidence and EBM, exploring the interplay of processes of professionalisation and distinction in shaping the evidence-based trajectories of nursing. We contrast these results with previous sociological writings on EBM, reflecting on the applicability and limitations of these theoretical positions when applied to the experiences of oncology clinicians.     

Occupational physicians' perceived value of evidence-based medicine intervention in enhancing their professional performance

OBJECTIVES: This study evaluated how physicians in a nonclinical setting perceive the value of an intervention with multifaceted evidence-based medicine with regard to enhancing their professional performance. METHODS: A qualitative study was conducted using focus groups and face-to-face interviews with 14 of the 48 Dutch occupational physicians who participated in the intervention. The intervention combined a didactic course in evidence-based medicine with recurrent case-method learning sessions. During the sessions, the participants were challenged to discuss their cases and to give one another feedback on how to find information on cases. RESULTS: Five main themes and four subthemes were identified: professional behavior and quality of care (subtheme: transparency): occupational physicians associated being up-to-date with quality of care, and evidence-based medicine was associated with improvements in professional standards; critical attitude and improved recommendations: occupational physicians asked themselves more-profound questions and searched more for information; sharing knowledge: the peer-group sessions facilitated the sharing of knowledge; communication (subthemes: colleagues, clients and other specialists): the more soundly based recommendations enhanced self-confidence positively and therefore altered interaction with medical specialists in particular; and satisfaction and barriers: the occupational physicians were especially content with the structured discussion in the peer-group sessions. However, the intervention was very time consuming. CONCLUSIONS: The participants regarded the intervention as a useful method for enhancing their professional performance. They stated that they became more up-to-date and more self-confident by searching for and sharing knowledge. These actions resulted in more scientifically based recommendations and improved interaction with clients and other specialists. However, time constraints remain an important barrier.     

Uncertainty and objectivity in clinical decision making: a clinical case in emergency medicine

The evidence-based practice and evidence-based medicine (EBM) movements have promoted standardization through guideline development methodologies based on systematic reviews and meta-analyses of best available research. EBM has challenged clinicians to question their reliance on practical reasoning and clinical judgement. In this paper, we argue that the protagonists of EBM position their mission as reducing uncertainty through the use of standardized methods for knowledge evaluation and use. With this drive towards uniformity, standardization and control comes a suspicion towards intuition, creativity and uncertainty as integral parts of medical practice. We question the appropriateness of attempts to standardize professional practice through a discussion of the importance of uncertainty. Greenhalgh’s taxonomy of uncertainty is used to inform an analysis of the clinical reasoning occurring in a potentially life threatening emergency situation with a young patient. The case analysis is further developed by the use of the Canadian philosopher Bernard Lonergan’s theory about understanding and objective knowing. According to Lonergan it is not by getting rid of or even by reducing uncertainty, but by attending systematically to it and by relating to it in a self-conscious way, that objective knowledge can be obtained. The paper concludes that uncertainty is not a regrettable and unavoidable aspect of decision making but a productive component of clinical reasoning.     

Needs assessment for health care management education in Russia

INTRODUCTION: For more than 70 years, health care management in the Soviet Union reflected a centralized directive style familiar to the Soviet political system. Market-oriented reform in post-Soviet Russia is pushing practicing physicians and physician-executives to acquire new information and skills regarding health care management. To assist with health care management in Russia, we analyzed health care providers' educational needs, as they perceive them. METHODS: A total of 4, 367 questionnaires were sent to practicing physicians and physician-executives in 3 regions of the Russian Federation. The questionnaires included 14 items designed to determine respondents' current levels of satisfaction and preferences for health care management education in Russia. RESULTS: There were 847 questionnaires returned, for a total response rate of 19.4%. Physicians were dissatisfied with the current status of health care management education, but they were interested in learning the skills of health care management. The health care legal system and computer systems and data analysis were the most popular courses requested; health care management and marketing were the least popular. Learning interests of executives differed from those of practicing physicians, and regions differed in their combined interests for courses. Medical school and continuing education departments were seen as the best choices for delivering health care management education. DISCUSSION: As health care policy shifts in new directions, physicians in leadership positions expect Russian medical schools and continuing education departments to provide courses that enable improvements in health care.     

Evidence-based medicine--method, critical appraisal and usefulness for professionalized business practice in medical

The concept of evidence-based medicine (EBM) describes 5 steps that lead to a scientifically based solution of clinical problems. EBM is often reduced to the search for the best evidence (randomised controlled trials, meta-analyses) or the introduction of guidelines. This causes criticism and may have consequences for medicine. But EBM also emphasizes the so-called clinical expertise of the doctor, which is important for reference to the individual patient. This point of EBM is being developed further. Connected with the theory of professionalization by U. Oevermann, stressing the importance of hermeneutical competence, EBM turns out to be a sophisticated model of professional medical practice.     

Who’s afraid of EBM? Medical professionalism from the perspective of evidence-based medicine

Evidence-based medicine (EBM) and medical professionalism are two prominent notions in current medical debates. However, proponents of professionalism fear a restriction in doctors’ freedom to make their best decisions for individual patients caused by the influence of EBM and highly standardised decision procedures. The challenge which EBM allegedly poses to physicians’ discretion forms the starting point for an analysis of the relationship between professionalism, as an inherent value system of medical practice, and EBM, as an approach to optimise the decision-making for individual patients. The analysis starts with a brief conceptual clarification of the ambiguous term “professionalism”. It then focuses on three key aspects of medical professionalism which may come into conflict with the basic tenets of EBM. The potential tensions between (a) professional autonomy and clinical practice guidelines, (b) individualised care and standardisation, and (c) esoteric authority and public accountability are analysed and a suggestion for reconcilement regarding each point is made. The article closes with a summary on how a better reflection on medical professionalism may help towards a fuller understanding of EBM and vice versa.     

Physician views on practicing professionalism in the corporate age

Arnold Relman argues that medical education does not prepare students and residents to practice their profession in today's corporate health care system. Corporate health care administrators agree: Physicians enter the workforce unskilled in contract negotiation, evidence-based medicine, navigating bureaucratic systems, and so forth. What about practicing physicians? Do they agree as well? According to this study, they do. Feeling like decentered double agents and unprepared, physicians find themselves professionally lost, struggling to balance issues of cost and care and expressing lots of negativity toward the cultures of medicine and managed care. However, physicians are resilient. A group of physicians, who may be called proactive, are meeting the professional demands of corporate health care by becoming sophisticated about its bureaucratic organization and the ways in which their professional and personal commitments fit within the system. Following the lead of proactive physicians, the authors support Relman's thesis and education for both students and physicians requires a major overhaul.     

Evidence-based medicine in primary care: qualitative study of family physicians

Background

The objectives of this study were: a) to examine physician attitudes to and experience of the practice of evidence-based medicine (EBM) in primary care; b) to investigate the influence of patient preferences on clinical decision-making; and c) to explore the role of intuition in family practice.

Method

Qualitative analysis of semi-structured interviews of 15 family physicians purposively selected from respondents to a national survey on EBM mailed to a random sample of Canadian family physicians.

Results

Participants mainly welcomed the promotion of EBM in the primary care setting. A significant number of barriers and limitations to the implementation of EBM were identified. EBM is perceived by some physicians as a devaluation of the 'art of medicine' and a threat to their professional/clinical autonomy. Issues regarding the trustworthiness and credibility of evidence were of great concern, especially with respect to the influence of the pharmaceutical industry. Attempts to become more evidence-based often result in the experience of conflicts. Patient factors exert a powerful influence on clinical decision-making and can serve as trumps to research evidence. A widespread belief that intuition plays a vital role in primary care reinforced views that research evidence must be considered alongside other factors such as patient preferences and the clinical judgement and experience of the physician.

Discussion

Primary care physicians are increasingly keen to consider research evidence in clinical decision-making, but there are significant concerns about the current model of EBM. Our findings support the proposed revisions to EBM wherein greater emphasis is placed on clinical expertise and patient preferences, both of which remain powerful influences on physician behaviour.

Family practice: professional identity in transition. A case study of family medicine in Canada

With increasingly fewer family physicians in many countries and students less interested in primary care careers, generalists are becoming an endangered species. This situation is a major health care resource management challenge. In a rapidly changing health care environment, family medicine is struggling for a clear identity-a matter which is crucial to health system restructuring because it affects the roles and functioning of other professions in the system. The objective of our study was to explore representations of roles and responsibilities of family physicians held by future family and specialist physicians and their clinical teachers in four Canadian medical school faculties of medicine, using both focus groups and individual interviews. In addition to family medicine, we targeted residency programs in general psychiatry, radiology and internal medicine-three areas that interface significantly between primary care and specialized medicine. In each faculty, respondents included the vice-dean of postgraduate studies; the director of each relevant program; educators in the program; residents in each specialty in their last year of training. Findings are centred around three major themes: (1) the definition of family medicine; (2) family medicine as an endangered species, and (3) the generation gap between young family physicians and their educators. The sustained physician-patient relationship is considered a core characteristic of family medicine that is much valued by patients and physicians-both generalists and specialists-as something to be preserved in any model of collaboration to be developed. Overall, two divergent directions emerge: preserving all the professions' traditional functions while adapting to changing contexts, or concentrating on areas of expertise and moving towards creating "specialist" general practitioners, in response to a rapidly expanding scope of practice, and to the high value attributed to specialization by society and the professional system.
