Kinds of Medical Practice Selected AbstractsJust What the Doctor Ordered: The Harrison Anti-Narcotic Act, the Supreme Court, and the Federal Regulation of Medical Practice, 1915,1919JOURNAL OF SUPREME COURT HISTORY, Issue 3 2001Kurt Hohenstein [source] ,You're judged all the time!' Students' views on professionalism: a multicentre studyMEDICAL EDUCATION, Issue 8 2010Gabrielle Finn Medical Education 2010: 44: 814,825 Objectives, This study describes how medical students perceive professionalism and the context in which it is relevant to them. An understanding of how Phase 1 students perceive professionalism will help us to teach this subject more effectively. Phase 1 medical students are those in the first 2 years of a 5-year medical degree. Methods, Seventy-two undergraduate students from two UK medical schools participated in 13 semi-structured focus groups. Focus groups, carried out until thematic saturation occurred, were recorded and transcribed verbatim. Data were analysed and coded using NVivo 8, using a grounded theory approach with constant comparison. Results, From the analysis, seven themes regarding professionalism emerged: the context of professionalism; role-modelling; scrutiny of behaviour; professional identity; ,switching on' professionalism; leniency (for students with regard to professional standards), and sacrifice (of freedom as an individual). Students regarded professionalism as being relevant in three contexts: the clinical, the university and the virtual. Students called for leniency during their undergraduate course, opposing the guidance from Good Medical Practice. Unique findings were the impact of clothing and the online social networking site Facebook on professional behaviour and identity. Changing clothing was described as a mechanism by which students ,switch on' their professional identity. Students perceived society to be struggling with the distinction between doctors as individuals and professionals. This extended to the students' online identities on Facebook. Institutions' expectations of high standards of professionalism were associated with a feeling of sacrifice by students caused by the perception of constantly ,being watched'; this perception was coupled with resentment of this intrusion. Students described the significant impact that role-modelling had on their professional attitudes. Conclusions, This research offers valuable insight into how Phase 1 medical students construct their personal and professional identities in both the offline and online environments. Acknowledging these learning mechanisms will enhance the development of a genuinely student-focused professionalism curriculum. [source] Workplace-based assessment for general practitioners: using stakeholder perception to aid blueprinting of an assessment batteryMEDICAL EDUCATION, Issue 1 2008Douglas J Murphy Context, The implementation of an assessment system may be facilitated by stakeholder agreement that appropriate qualities are being tested. This study investigated the extent to which stakeholders perceived 8 assessment formats (multiple-choice questions, objective structured clinical examination, video, significant event analysis, criterion audit, multi-source feedback, case analysis and patient satisfaction questionnaire) as able to assess varying qualities of doctors training in UK general practice. Methods, Educationalists, general practice trainers and registrars completed a blueprinting style of exercise to rate the extent to which each evaluation format was perceived to assess each of 8 competencies derived primarily from the General Medical Council document Good Medical Practice. Results, There were high levels of agreement among stakeholders regarding the perceived qualities tested by the proposed formats (G = 0.82,0.93). Differences were found in participants' perceptions of how well qualities were able to be assessed and in the ability of the respective formats to test each quality. Multi-source feedback (MSF) was expected to assess a wide range of qualities, whereas Probity, Health and Ability to work with colleagues were limited in terms of how well they could be tested by the proposed formats. Discussion, Awareness of the perceptions of stakeholders should facilitate the development and implementation of workplace-based assessment (WPBA) systems. These data shed light on the acceptability of various formats in a way that will inform further investigation of WPBA formats' validity and feasibility, while also providing evidence on which to base educational efforts regarding the value of each format. [source] Application of Telemedicine in a Pain Clinic: The Changing Face of Medical PracticePAIN MEDICINE, Issue 4 2000Rouzanna Burton MS Telemedicine systems aim to provide quality health care services to persons whose access is otherwise restricted by geography and environment. The military medical department has a unique mission to provide all medical care for the battlefields and peacekeeping missions anywhere in the world. In addition, the medical department has to ensure the health of all soldiers, family members, and retirees during peacetime. Hospital closures coupled with a decreased number of military physicians have left many health care beneficiaries without readily available specialty care. They face long waiting lists or incur high out-of-pocket expenses in order to see medical specialists. As a result of the establishment of a virtual Telepain clinic, 56,400 miles were saved in patient and clinician travel. Use of technologies in the emerging field of telemedicine has lead to the creation of numerous military and civilian medical applications such as virtual dermatology, virtual psychiatry, virtual cardiology, virtual nuclear medicine/radiology, virtual pharmacology, and in future, virtual dentistry and ophthalmology. [source] Emergency Medical Practice: Advancing Cultural Competence and Reducing Health Care DisparitiesACADEMIC EMERGENCY MEDICINE, Issue 1 2009Aasim I. Padela MD Abstract In an increasingly diverse patient population, language differences, socioeconomic circumstances, religious values, and cultural practices may present barriers to the delivery of quality care. These obstacles contribute to the health care disparities observed in all areas of medical care. Increasing cultural competence has been cited as part of the solution to reduce disparities. The emergency department (ED) is an environment where cultural sensitivity is particularly needed, as it is often a primary source of health care for the underserved and ethnic and racial minorities and a place where high patient volume and acuity place the provider under demanding time pressures, yet the emergency medicine (EM) literature on health care disparities and cultural competence is limited. The authors present three clinical scenarios highlighting challenges in providing equitable emergency care to minority populations. Using these cases as illustrations, three processes are proposed that may improve the quality of care delivered to minority populations: 1) increase cultural awareness and reduce provider biases, enabling providers to interact more effectively with different patient populations; 2) accommodate patient preferences and needs in medical settings through practice adjustments and cultural modifications; and 3) increase provider diversity to raise levels of tolerance, awareness, and understanding for other cultures and create more racially and/or ethnically concordant patient,physician relationships. [source] Medical practice, procedure manuals and the standardisation of hospital deathNURSING INQUIRY, Issue 1 2009Hans Hadders This paper examines how death is managed in a larger regional hospital within the Norwegian health-care. The central focus of my paper concerns variations in how healthcare personnel enact death and handle the dead patient. Over several decades, modern standardised hospital death has come under critique in the western world. Such critique has resulted in changes in the standardisation of hospital deaths within Norwegian health-care. In the wake of the hospice movement and with greater focus on palliative care, doors have gradually been opened and relatives of the deceased are now more often invited to participate. I explore how the medical practice around death along with the procedure manual of post-mortem care at Trondheim University Hospital has changed. I argue that in the late-modern context, standardisation of hospital death is a multidimensional affair, embedded in a far more comprehensive framework than the depersonalised medico-legal. In the late-modern Norwegian hospital, interdisciplinary negotiation and co-operation has allowed a number of different agendas to co-exist, without any ensuing loss of the medical power holder's authority to broker death. I follow Mol's notion of praxiographic orientation of the actor,network approach while exploring this medical practice. [source] Evidence-Based Medicine and Clinical Trials in Pain Practice and OrthopedicsPAIN PRACTICE, Issue 4 2005Ludger Gerdesmeyer MD Abstract: Medical practices should be based on scientific findings pursuant to the rules of evidence-based medicine. Quality standards for interventional pain therapy and orthopedic clinical studies have been lacking. As a result, the efficacy of many forms of therapy is insufficiently documented, making the level of evidence low. This article identifies common deficiencies in the conduct of clinical trials, as well as limitations in conducting randomized controlled studies. Recommendations for improvement are provided. The discussion provides the clinically active physician with interpretation aids for the evaluation of meta-analyses, supports personal evidence-based decisions, and reviews the most important principles for planning and conducting of experimental clinical studies. Current examples in the literature verify the implementation of these principles and present current findings in accordance with evidence-based medicine (EBM) criteria. In spite of an increasing emergence of EBM-based studies, we conclude that the number of well-designed, high quality, controlled studies conducted in accordance with the guidelines of Good Clinical Practice examining interventional pain therapy and orthopedic clinical studies remains unacceptably low. [source] Demonstrably Awful: The Right to Life and the Selective Non-Treatment of Disabled Babies and Young ChildrenJOURNAL OF LAW AND SOCIETY, Issue 4 2004Janet Read Twenty-five years ago it was common practice to bring about the deaths of some children with learning disabilities or physical impairments. This paper considers a small number of landmark cases in the early 1980s that confronted this practice. These cases illustrate a process by which external forces (social, philosophical, political, and professional) moved through the legal system to effect a profound change outside that system , primarily in the (then) largely closed domain of medical conduct/practice. These cases are considered from a socio-legal perspective. In particular, the paper analyses the reasons why they surfaced at that time, the social and political contexts that shaped the judgments, and their legacy. [source] Development without Institutions: Ersatz Medicine and the Politics of Everyday Life in Rural North IndiaCULTURAL ANTHROPOLOGY, Issue 3 2004Sarah Pinto In north India, unregulated medical practice is considered by many to be a sign of the failure of institutional rationality and "backward" quality of rural life. However, the work of self-made doctors can also be seen to engage key elements of institutional rationality as it is interwoven with the structure and ethos of development. This article explores what these practitioners and their work suggest about the imagination of institutions in rural India and the kinds of power this invokes. Through mimesis of key practices (namely, forms of talk and use of injections), self-made doctors tap into the authority of legitimate institutions to occupy lacunae in state health structures and redress (even as they reproduce) effects of privatization and repeated temporary health measures. At the same time, everyday elements of these practices demonstrate that institutional legitimacy can only be borrowed by those already in positions of authority (on the basis of caste status and political leadership), challenging ideals of equality that underlie health-related development efforts. [source] Efficacy, Safety, and Cost of Office-Based Surgery: A Multidisciplinary PerspectiveDERMATOLOGIC SURGERY, Issue 1 2003Rajesh Balkrishnan PhD An increasing number of media reports on patient safety risks arising from office-based surgery procedures, as well as growing concerns about patient safety issues in general, have brought office-based surgery as well as its practitioners into focus and placed this very cost-effective medical practice in the eye of the media and regulators. Concerted efforts are now being made to understand the causes and true incidence of patient safety risk associated with office-based surgery and to find ways to minimize this risk. [source] THE THERAPEUTIC EXCEPTION: ABORTION, STERILIZATION AND MEDICAL NECESSITY IN COSTA RICADEVELOPING WORLD BIOETHICS, Issue 2 2007MARÍA CARRANZA ABSTRACT Based on the case of Rosa, a nine-year-old girl who was denied a therapeutic abortion, this article analyzes the role played by the social in medical practice. For that purpose, it compares the different application of two similar pieces of legislation in Costa Rica, where both the practice of abortion and sterilization are restricted to the protection of health and life by the Penal Code. As a concept subject to interpretation, a broad conception of medical necessity could enable an ample use of the therapeutic exception and a liberal use of both surgeries. The practice of therapeutic sterilization has been generalized in Costa Rica and has become the legitimate way to distribute contraceptive sterilization. In contrast, therapeutic abortion is very rarely practiced. The analysis carried out proposes that it is the difference in social acceptance of abortion and sterilization that explains the different use that doctors, as gatekeepers of social morality, make of medical necessity. [source] Mephentermine dependence without psychosis: a Brazilian case reportADDICTION, Issue 6 2010Henrique Faria De Sousa ABSTRACT Background Substance abuse is a serious health concern. This report presents the case of a 22-year-old Brazilian man with a history of mephentermine use who fulfils all the criteria for chemical dependence listed by ICD-10. Mephentermine is a sympathomimetic agent derived from methamphetamine which, in Brazil, is restricted to veterinary use. Case description The subject used the substance at a high dose (120 mg) to improve his physical performance while working out at a gym. His symptoms included anorexia and insomnia. After days of intense activity, he felt fatigue and soreness. A physical examination revealed scars on both forearms from the injections and a psychological examination revealed moderate speech and motor agitation. Conclusions Cases such as this may be common among the general public. They should have some bearing upon medical practice and public health policies involving drugs. [source] Clinical Information Systems: Instant Ubiquitous Clinical Data for Error Reduction and Improved Clinical OutcomesACADEMIC EMERGENCY MEDICINE, Issue 11 2004Craig F. Feied MD Abstract Immediate access to existing clinical information is inadequate in current medical practice; lack of existing information causes or contributes to many classes of medical error, including diagnostic and treatment error. A review of the literature finds ample evidence to support a description of the problems caused by data that are missing or unavailable but little evidence to support one proposed solution over another. A primary recommendation of the Consensus Committee is that hospitals and departments should adopt systems that provide fast, ubiquitous, and unified access to all types of existing data. Additional recommendations cover a variety of related functions and operational concepts, from backups and biosurveillance to speed, training, and usability. [source] An Approach to Fulfilling the Systems-based Practice Competency RequirementACADEMIC EMERGENCY MEDICINE, Issue 11 2002David Doezema MD The Accreditation Council for Graduate Medical Education (ACGME)-identified core competency of systems-based practice requires the demonstration of an awareness of the larger context and system of health care, and the ability to call on system resources to provide optimum care. This article describes an approach to teaching and fulfilling the requirement of this core competency in an emergency medicine residency. Beginning residents are oriented to community resources that are important to the larger context of care outside the emergency department. Each resident completes a community project during his or her residency. Readings and discussions concerning community-oriented medical care and the literature of research and injury prevention in emergency medicine precede the project development. Several projects are described in detail. Such projects help to teach not only awareness of the community resources of the greater context of medical practice outside the emergency department, but also how to use those resources. Projects could be a main component of a resident portfolio. This approach to teaching the core competency of systems-based practice is proposed as an innovative and substantial contribution toward satisfying the requirement of the core competency. [source] Alcohol screening and brief intervention: dissemination strategies for medical practice and public healthADDICTION, Issue 5 2000Thomas F. Babor This paper introduces the concept of risky drinking and considers the potential of alcohol screening and brief intervention (SBI) to reduce alcohol-related problems in medical practice and in organized systems of health care. The research evidence behind this approach is reviewed. Potential strategies for the dissemination of SBI to systems of health care are then discussed within the context of a public health model of clinical preventive services. There is an emerging consensus that SBI should be promoted in general healthcare settings, but further research is needed to determine the best ways to achieve widespread dissemination. In an attempt to provide an integrative model that is relevant to SBI, dissemination strategies are discussed for three target groups: (1) individual patients and practitioners; (2) health care settings and health systems; and (3) the communities and the general population. Dissemination strategies are considered from the fields of social change, social science, commercial marketing and education in terms of their potential for translating SBI innovations into routine clinical practice. One overarching strategy implicit in the approaches reviewed in this article is to embed alcohol SBI in the more general context of preventive health services, the utility of which is becoming increasingly recognized as a critical supplement to more traditional clinical medicine. [source] Neurophysiological and neurochemical basis of modern pruritus treatmentEXPERIMENTAL DERMATOLOGY, Issue 3 2008Sonja Ständer Abstract:, Chronic pruritus of any origin is a frequent discomfort in daily medical practice, and its therapy is challenging. Frequently, the underlying origin may not be identified and symptomatic therapy is necessary. Conventional treatment modalities such as antihistamines often lack efficacy, and hence new therapeutic strategies are necessary. The neuronal mechanisms underlying chronic pruritus have been partly identified during the past years and offer new therapeutic strategies. For example, mast cell degranulation, activation of neuroreceptors on sensory nerve fibres and neurogenic inflammation have been identified to be involved in induction and chronification of the symptom. Accordingly, controlling neuroreceptors such as cannabinoid receptors by agonists or antagonists showed high antipruritic efficacy. Pruritus is transmitted to the central nervous system by specialized nerve fibres and sensory receptors. It has been demonstrated that pruritus and pain have their own neuronal pathways with broad interactions. Accordingly, classical analgesics for neuropathic pain (gabapentin, antidepressants) also exhibit antipruritic efficacy upon clinical use. In summary, these recent developments show that highlighting the basis of pruritus offers modern neurophysiological and neurochemical therapeutic models and the possibility to treat patients with refractory itching of different origin. [source] Coxibs: evolution of prescription's behaviour in FranceFUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 3 2007Julie Biga Abstract The aim of the present study was, first to characterize profiles of coxibs' prescribers [general practitioners (GPs) and rheumatologists] in 2002 in France and, secondly, to identify factors associated with modification of this profile 1 year later. All GPs and rheumatologists from Midi-Pyrenees, Aquitaine, Languedoc-Roussillon and Pays de Loire areas (South of France: 11 050 000 inhabitants) were included in the study. For each practitioner, we used data concerning all non-steroidal anti-inflammatory drugs (NSAIDs) including coxibs reimbursed during period 1 (P1; January,March 2002) and period 2 (P2; January,March 2003). The ratio between the number of coxibs' prescriptions and the total number of NSAIDs' prescriptions (including coxibs) was used to define the two profiles of prescribers, one with a low level of coxibs' prescriptions and another one with a high level of coxibs' prescriptions. Characteristics of practitioners and characteristics of their practices were compared according to this profile. In the second step, we investigated the characteristics (of practitioners and practices) associated with an increase in the level of coxibs' prescriptions in P2 for practitioners with a low level of coxibs' prescriptions in P1. Results are expressed as odds ratio with their 95% confidence intervals. A positive statistical link was found between a high level of coxibs' prescriptions, the speciality of rheumatologist or extra costs for consultation. In contrast, a negative association was observed with female gender or age below 44 years. No relationship was found with the status of referent. Concerning practices' characteristics of practitioners, there was a positive statistical link between a high ratio of coxibs' prescriptions and high co-prescriptions of gastroprotective agents and a negative association with a high number of acts, a high proportion of patients with chronic disabling diseases (CDD) or a high number of patients between 15 and 64 years. There was no statistical link with proportion of patients covered by Universal Medical Coverage (UMC) or aged more than 65 years. Among the factors involved in the increase in the ratio (between P1 and P2), no relationship was found with practitioners' characteristics. In contrast, some factors related to practices (level of gastroprotective co-prescriptions, number of acts, number of CDD patients) were related to a change in coxibs' prescriptions between P1 and P2. This study allowed to discuss some relationships between coxibs' prescription and practitioners' (age, gender, medical speciality or extra costs for consultation) or practices' (level of medical practice, patients' age, number of CDD patients or level of gastroprotective prescriptions) characteristics. In contrast, some other factors like the referent status or the number of patients with UMC are not related. Physicians, initially low prescribers of coxibs and increasing their coxibs' prescriptions during the period of our study, were those with a high level of gastroprotective prescriptions, a low number of acts or a small proportion of CDD patients. [source] How to measure non-consistency of medical practices with available evidence in therapeutics: a methodological frameworkFUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 5 2005Jean-Pierre Boissel Abstract Since the early 1980s many studies showed a gap between available evidence and medical practice. They were designed to assess the real impact of randomized clinical trials on the practice of medicine. Their results substantiated a knowledge translation problem. However, they were qualitative findings, i.e. a gap exists or not, although the problem is quantitative (how large is the gap?) and has several components that should be documented according to the objective of the study. In this article, we explored the components and the various contexts in which the measure of the distance between practice and knowledge is considered. All these features should be taken into account for a more accurate and relevant assessment of the distance. [source] Gendering the History of Women's HealthcareGENDER & HISTORY, Issue 3 2008Monica H. Green This essay examines the genesis and continuing influence of certain core narratives in the history of western women's healthcare. Some derive from first-wave feminism's search for models of female medical practice, an agenda that paid little attention to historical context. Second-wave feminism, identifying a rift between pre-modern and modern times in terms of women's medical practices, saw the pre-modern European female healer as an exceptionally knowledgeable empiricist, uniquely responsible for women's healthcare and (particularly because of her knowledge of mechanisms to limit fertility) a victim of male persecution. Aspects of this second narrative continue subtly to effect scholarly discourse and research agendas on the history of healthcare both by and for women. This essay argues that, by seeing medical knowledge as a cultural product , something that is not static but continually re-created and sometimes contested , we can create an epistemology of how such knowledge is gendered in its genesis, dissemination and implementation. Non-western narratives drawn from history and medical anthropology are employed to show both the larger impact of the western feminist narratives and ways to reframe them. [source] Behavioral Facilitation of Medical Treatment for Headache,Part II: Theoretical Models and Behavioral Strategies for Improving AdherenceHEADACHE, Issue 9 2006Jeanetta C. Rains PhD This is the second of 2 articles addressing the problem of noncompliance in medical practice and, more specifically, compliance with headache treatment. The companion paper describes the problem of noncompliance in medical practice and reviews literature addressing compliance in headache care (Behavioral Facilitation of Medical Treatment for Headache,Part I: Review of Headache Treatment Compliance). The present paper first summarizes relevant health behavior theory to help account for the myriad biopsychosocial determinants of adherence, as well as patient's shifting responsiveness or "readiness for change" over time. Appreciation of health behavior models may assist in optimally tailoring interventions to patient needs through instructional, motivational, and behavioral treatment strategies. A wide range of specific cognitive and behavioral compliance-enhancing interventions are described, which may facilitate treatment adherence among headache patients. Strategies address patient education, patient/provider interaction, dosing regimens, psychiatric comorbidities, self-efficacy enhancement, and other behavioral interventions. [source] Etiology and Distribution of Headaches in Two Brazilian Primary Care UnitsHEADACHE, Issue 3 2000Marcelo E. Bigal MD Objectives.,To determine (a) which patients seek primary care services with a complaint of headache, (b) the percentages of the various types of headache in this population, and (c) the impact of the care provided to these patients on the basic health care network. Background.,Headache is one of the most frequent symptoms reported in medical practice, resulting in significant medical services costs and loss of patient productivity, as well as reduced quality of life. Methods.,A prospective study was conducted in two towns (Ribeirão Preto and São Carlos) in the State of São Paulo, Brazil. The participants in the study consisted of 6006 patients (52.4% women) with highly varied acute symptoms. The patients ranged in age from 14 to 98 years. Results.,Headache as the main complaint was reported by 561 (9.3%) of the patients considered, with 312 (55.6%) of those patients presenting with primary headache, 221 (39.4%) with headaches secondary to systemic disorders, and 28 (5.0%) with headaches secondary to neurological disorders. Migraine, the most prevalent primary headache, accounted for 45.1% of patients reporting headache as the single symptom. The most frequent etiologies of headaches secondary to systemic disorders were fever, acute hypertension, and sinusitis. The most frequent headaches secondary to neurological disorders were posttraumatic headaches, headaches secondary to cervical disease, and expansive intracranial processes. Of the 26 cases of drug abuse, 20 were secondary to alcohol (hangover). Headaches secondary to systemic disorders were more frequent in the extreme age ranges. Conclusions.,Headache is a very frequent symptom among patients seen at primary health care units and should be considered a public health problem. The dissemination of the diagnostic criteria of the International Headache Society among primary health care physicians is urgently needed in order to avoid the repeated return of patients or their referral to more differentiated emergency units, which overburden an already insufficient health care network. [source] European health policy challengesHEALTH ECONOMICS, Issue S1 2005Alan Maynard Abstract Few countries are immune to the international health care ,virus' of reform, with many countries regularly re-cycling changes that shift costs and benefits in ways that are arbitrary, inefficient and offer short term political palliation. Much of this activity has little evidence base and reveals lack of clarity in defining public policy goals, establishing trade-offs and aligning incentive structures with these objectives. Well established failures in health care delivery systems such as variations in medical practice and continuing absence of systematic outcome measurement, have persisted for decades as nations grapple inefficiently with recurring problems of expenditure inflation and waiting times. The lack of emphasis on evidence to inform the efficient management of chronic disease and the reduction of health inequalities is a product of perverse incentives and managerial inertia that maintains the incomes of powerful interest groups.

[source] Toward a Continuous Quality Improvement Paradigm for Hemodialysis Providers with Preliminary Suggestions for Clinical Practice Monitoring and MeasurementHEMODIALYSIS INTERNATIONAL, Issue 1 2003Edmund G. Lowrie Background: Consensus processes using the clinical literature as the primary source for information generally drive projects to draft clinical practice guidelines (CPGs). Most such literature citations describe special projects that are not part of an organized quality management initiative, and the publication/review/consensus process tends to be long. This project describes an initiative to develop and explore a flexible and dedicated data-driven paradigm for deciding new CPGs that could be rapidly responsive to changing medical knowledge and practice. Methods: Candidate Clinical Practice Monitoring Measures (CPMM) were selected using a large, national database according to the natures and strengths of their associations with mortality risk among patients during 1994. Thresholds above or below which risk of death increased were evaluated for each CPMM using risk profile charts and spline functions. The fractions of patients outside of those thresholds in each dialysis unit (the %Var) were determined for the years 1993, 1994, and 1995. A standardized mortality ratio (SMR) was also determined for each year for each facility. The associations between the %Var and SMR were evaluated in several single-variable and multivariable statistical models. Results: Eleven CPMM were selected and evaluated based on their associations with death risk. These included the urea clearance x dialysis time product (Kt); the concentrations of albumin, potassium, phosphate, bicarbonate, hemoglobin, neutrophils, and lymphocytes in the blood; the body weight/height ratio; diastolic blood pressure; and vascular access type. Even though the CPMM were strongly associated with death risk among patients, the %Var were weakly and inconsistently associated with SMR among facilities. Conclusions: The paradigm was flexible, easy to implement, quickly executed, and potentially able to accommodate evolving medical practice assuming the availability of large database systems such as this. The primary associates of death risk were easily identified and the thresholds easily adopted. The SMR and %Var from the CPMM were only weakly associated, however, suggesting that one cannot be reliably predicted from the other. As such, quality management programs should likely monitor both the processes and outcomes of care among dialysis facilities. [source] Biliary physiology and disease: Reflections of a physician-scientist,HEPATOLOGY, Issue 4 2010Gustav Paumgartner A review is presented of Gustav Paumgartner's five decades of research and practice in hepatology focusing on biliary physiology and disease. It begins with studies of the excretory function of the liver including hepatic uptake of indocyanine green, bilirubin, and bile acids. The implications of these studies for diagnosis and understanding of liver diseases are pointed out. From there, the path of scientific research leads to investigations of hepatobiliary bile acid transport and the major mechanisms of bile formation. The therapeutic effects of the hydrophilic bile acid, ursodeoxycholic acid, have greatly stimulated these studies. Although ursodeoxycholic acid therapy for dissolution of cholesterol gallstones and some other nonsurgical treatments of gallstones were largely superseded by surgical techniques, ursodeoxycholic acid is currently considered the mainstay of therapy of some chronic cholestatic liver diseases, such as primary biliary cirrhosis. The major mechanisms of action of ursodeoxycholic acid therapy in cholestatic liver diseases are discussed. An attempt is made to illustrate how scientific research can lead to advances in medical practice that help patients. (HEPATOLOGY 2010:51:1095,1106.) [source] Depression and practice guidelinesHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 1 2001John S Mcintyre Abstract Over the past two decades there have been great advances in the understanding of depression and in the development of pharmacological agents and psychosocial treatments that have demonstrated efficacy in the treatment of this common and disabling illness. Unfortunately, this knowledge and evidence is not consistently translated into actual treatment, and depression remains undiagnosed in a large percentage of patients, and when it is accurately diagnosed, it often is suboptimally treated. The frequent failure to properly diagnose depression may be due to the continuing stigma of mental illness, the persistence of the biomedical, rather than the biopsychosocial, paradigm of illness and treatment, educational issues and the time constraints in the typical medical practice. The suboptimal treatment may be due to all of these issues plus the difficulty in changing physician behaviours even when there exists much evidence that would seem to dictate such a change. The development of a criteria-based nomenclature and the subsequent development and dissemination of evidence-based practice guidelines addresses some of these issues. Copyright © 2001 John Wiley & Sons, Ltd. [source] Intercenter variation in initial management of children with Crohn's diseaseINFLAMMATORY BOWEL DISEASES, Issue 7 2007Michael D. Kappelman MD Abstract Background: Variation in care is a ubiquitous feature of medical practice and may lead to significant differences in health care costs, quality, and outcomes. We undertook this study to determine the extent of intercenter variation in the initial management of children newly diagnosed with Crohn's disease. Methods: We analyzed the utilization of 5 classes of medication (immunomodulators, prednisone, antibiotics, 5-aminosalicylates, and infliximab) among 311 children with newly diagnosed Crohn's disease followed at 10 North American pediatric gastroenterology centers. Multivariate logistic regression was used to compare the utilization rate of each class of medication at each of the 10 centers, adjusting for potential confounders including patient age, sex, race, disease severity, and anatomic location of disease. Results: Median utilization of each class of medication was: immunomodulators, 56% (range 29%,97%); prednisone, 78% (range 32%,88%); antibiotics, 29% (range 11%,68%); 5-aminosalicylates, 63.5% (range 18%,92%); and infliximab, 7.5% (range 3%,21%). Each of these treatments showed statistically significant intercenter variation in utilization (P < 0.001 for immunomodulators, prednisone, antibiotics, and 5-ASA; P = 0.02 for infliximab). After adjusting for the demographic and clinical factors listed above, intercenter variation remained significant; however, the low utilization of infliximab precluded multivariate analysis. Conclusions: Widespread intercenter variation in the medical management of newly diagnosed children with Crohn's disease was observed, even after adjusting for possible differences in case mix between institutions. This variation may lead to unintended differences in health care costs and outcomes. (Inflamm Bowel Dis 2007) [source] Are Australasian academic physicians an endangered species?INTERNAL MEDICINE JOURNAL, Issue 11 2007A. Wilson Abstract It has been stated that academic medicine is in a worldwide crisis. Is this decline in hospital academic practice a predictable consequence of modern clinical practice with its emphasis on community and outpatient-based services as well as a corporate health-care ethos or does it relate to innate problems in the training process and career structure for academic clinicians? A better understanding of the barriers to involvement in academic practice, including the effect of gender, the role and effect of overseas training, expectation of further research degrees and issues pertaining to the Australian academic workplace will facilitate recruitment and retention of the next generation of academic clinicians. Physician-scientists remain highly relevant as medical practice and education evolves in the 21st century. Hospital-based academics carry out a critical role in the ongoing mentoring of trainees and junior colleagues, whose training is still largely hospital based in most specialty programmes. Academic clinicians are uniquely placed to translate the rapid advances in medical biology into the clinical sphere, by guiding and carrying out translational research as well as leading clinical studies. Academic physicians also play key leadership in relations with government and industry, in professional groups and medical colleges. Thus, there is a strong case to assess the problems facing recruitment and retention of physician-scientists in academic practice and to develop workable solutions. [source] Prediction rules for computed tomography in the dementia assessment: do they predict clinical utility of CT?INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 4 2003Kelly A. Condefer Abstract Neuroimaging is widely employed in the dementia assessment in refining clinical decision-making. However, with rising interest in cost-effective medical practice, efforts have been made in the literature to define clinical prediction rules that select for a subgroup of patients who would most likely benefit from neuroimaging. This short study examined the ability of a group of published clinical predictors to identify patients whose diagnoses or management would be influenced by CT scan results. The study finds that none of the published predictors bears a significant relationship to actual influence of CT scans in a group of memory clinic patients, highlighting the need for the development of clinical predictors for neuroimaging that will impact patient care.

A study from Attock District of Pakistan assessed this problem in the formal allopathic health sector and compared prescribing practices of health care providers in the public and private sector. WHO recommended drug use indicators were used to study prescription practices. Prescriptions were collected from 60 public and 48 private health facilities. The mean (±,SE) number of drugs per prescription was 4.1,±,0.06 for private and 2.7,±,0.04 for public providers (,p,<,0.0001). General practitioners (GPs) who represent the private sector prescribed at least one antibiotic in 62% of prescriptions compared with 54% for public sector providers. Over 48% of GP prescriptions had at least one injectable drug compared with 22.0% by public providers (,p,<,0.0001). Thirteen percent of GP prescriptions had two or more injections. More than 11% of GP prescriptions had an intravenous infusion compared with 1% for public providers (,p,<,0.001). GPs prescribed three or more oral drugs in 70% of prescriptions compared with 44% for public providers (,p,<,0.0001). Prescription practices were analysed for four health problems, acute respiratory infection (ARI), childhood diarrhoea (CD), fever in children and fever in adults. For these disorders, both groups prescribed antibiotics generously, however, GPs prescribed them more frequently in ARI, CD and fever in children (,p,<,0.01). GPs prescribed steroids more frequently, however, it was significantly higher in ARI cases (,p,<,0.001). For all the four health problems studied, GPs prescribed injections more frequently than public providers (,p,<,0.001). In CD cases GPs prescribed oral rehydration salt (ORS) less frequently (33.3%) than public providers (57.7%). GPs prescribed intravenous infusion in 12.3% cases of fever in adults compared with none by public providers (,p,<,0.001). A combination of non-regulatory and regulatory interventions, directed at providers as well as consumers, would need to be implemented to improve prescription practices of health care providers. Regulation alone would be ineffective unless it is supported by a well-established institutional mechanism which ensures effective implementation. The Federal Ministry of Health and the Provincial Departments of Health have to play a critical role in this respect, while the role of the Pakistan Medical Association in self-regulation of prescription practices can not be overemphasized. Improper prescription practices will not improve without consumer targeted interventions that educate and empower communities regarding the hazards of inappropriate drug use.

M. Atkins Abstract In response to a climate of constant change and increasing demand for services, general practice in the UK has undergone significant modification over the last 10 years. It has become a multi-disciplinary organisation encouraged by funding bodies to plan for service delivery using a more structured team based approach. In Tayside in 1996, practices were charged with producing formal Practice Development Plans (PDPs) which would focus on priority areas aligned with the Health Boards own strategic plan,those were teamwork, information management and technology, and clinical service delivery. The University of Dundee's Department of General Practice successfully applied for funding to develop ways of facilitating practices so that they could a) identify their own development priorities, and b) plan and implement action and learning to see these priorities through. Using action research methodology, the project attempted to create a climate for change, provide support and training to see the changes implemented, and ensure commitment to the changes from all members of the practice team. The Facilitator adopted a flexible style varying her role between expert, guide and support. Analysis of progress made by different practices, coupled with the Facilitator's in depth knowledge of them, suggested the importance of certain key aspects of practice organisation and culture. A practice characterisation model identified practices which were stable, currently coping, proactive and ready to face the challenge of change as best placed to engage in a full scale development programme. Other profiles suggested a range of alternative interventions as more likely to be acceptable and productive. [source] | ||||||||||||||||||||||||||||||||||||||||
