    Full Text Available The paper describes the results of research aimed at assessing the current conditions related to clinical laboratory technologist professional development. A descriptive cross study covering the period between November 2013 and January 2014 is presented. Several techniques for identifying and hierarchically arranging professional developmental related problems were used to study a sample at the Faculty of Health Technology of the Medical University “Carlos Juan Finlay”. The study involved heads of teaching departments and methodologists of health care technology specialties; moreover a survey and a content test were given graduate clinical laboratory technicians. The authors reached at the conclusion that clinical laboratory technologist professional development is limited and usually underestimate the necessities and interests of these graduates. Likewise, a lack of systematization and integration of the biomedical basic sciences contents and the laboratory diagnosis is noticeable.

  2. From professional monopoly to corporate oligopoly:the clinical laboratory industry in transition.

    Bailey, R M

    1977-02-01

    Until the mid-1960s the nonhospital clinical laboratory industry was dominated by pathologists. The ethics of medical professionalism protected the pathologists' market from price competition and from any serious threat from new entrants into the market. Immune from the competitive pressures of the marketplace, pathologists exerted monopoly control in local markets. That power was eroded by laboratories operated by technologists and bioanalysts and was finally overcome by the entry of large corporations into the industry. The market power of the largest corporate laboratories is now growing to a point where competition may again be thwarted. The professional ethics of pathologists allowed high prices, but there was little push toward higher volume. The commercial ethics of the corporate entrants brought lower prices but resulted in strong pressure for greater test quantities. In either case, the power wielded by the dominant producer would seem to go against the consumer's interests.

    Background : The aim of this study was to determine the level of knowledge and practices about toxoplasmosis in a sample of clinical laboratory professionals in Mexico. Methods : 192 clinical laboratory professionals were surveyed. They were asked about (1) Toxoplasma gondii ; (2) clinical manifestations, diagnosis, treatment, and epidemiology of toxoplasmosis; and (3) their practices with respect to toxoplasmosis. Results : The range of animals infected by T. gondii was known by 44.8% of participants. Clinical aspects of toxoplasmosis were known by up to 44.3% of subjects. Correct answers about the interpretation of serological markers of T. gondii infection were provided by up to 32.8% of participants. A minority (32.2%) of participants knew about a high number of false positive results of anti- T. gondii IgM antibody tests. Most participants (90.1%) did not know what the anti- T. gondii IgG avidity test was. Up to 55.7% of participants provided incorrect answers about the interpretation of serology tests for the treatment of pregnant women. Common routes of T. gondii infection were known by toxoplasmosis and a limited practice of laboratory tests among the professionals surveyed.

    2015-05-01

    The manner in which medical care is reimbursed in the United States has resulted in significant consolidation in the U.S. health care system. One of the consequences of this has been the development of centralized clinical microbiology laboratories that provide services to patients receiving care in multiple off-site, often remote, locations. Microbiology specimens are unique among clinical specimens in that optimal analysis may require the maintenance of viable organisms. Centralized laboratories may be located hours from patient care settings, and transport conditions need to be such that organism viability can be maintained under a variety of transport conditions. Further, since the provision of rapid results has been shown to enhance patient care, effective and timely means for generating and then reporting the results of clinical microbiology analyses must be in place. In addition, today, increasing numbers of patients are found to have infection caused by pathogens that were either very uncommon in the past or even completely unrecognized. As a result, infectious disease specialists, in particular, are more dependent than ever on access to high-quality diagnostic information from clinical microbiology laboratories. In this point-counterpoint discussion, Robert Sautter, who directs a Charlotte, NC, clinical microbiology laboratory that provides services for a 40-hospital system spread over 3 states in the southeastern United States explains how an integrated clinical microbiology laboratory service has been established in a multihospital system. Richard (Tom) Thomson of the NorthShore University HealthSystem in Evanston, IL, discusses some of the problems and pitfalls associated with large-scale laboratory consolidation.

    The University of Texas M.D. Anderson Cancer Center, Division of Pathology and Laboratory Medicine is committed to providing the best pathology and medicine through: state-of-the art techniques, progressive ground-breaking research, education and training for the clinical diagnosis and research of cancer and related diseases. After surveying the laboratory staff and other hospital professionals, the Department administrators and Human Resource generalists developed a professional development model for Microbiology to support laboratory skills, behavior, certification, and continual education within its staff. This model sets high standards for the laboratory professionals to allow the labs to work at their fullest potential; it provides organization to training technologists based on complete laboratory needs instead of training technologists in individual areas in which more training is required if the laboratory needs them to work in other areas. This model is a working example for all microbiology based laboratories who want to set high standards and want their staff to be acknowledged for demonstrated excellence and professional development in the laboratory. The PDM model is designed to focus on the needs of the laboratory as well as the laboratory professionals.

    Out-of-state flat-rate mail order contract laboratories operating from states which have little or no legal control over them can do business in California without obedience to regulations that govern laboratories located within the state. The flat-rate contract principle under which some out-of-state laboratories operate is illegal in California. The use of such laboratories increases physician liability. Legislation for the control of these laboratories is difficult to construct, and laws which might result would be awkward to administer. The best remedy is for California physicians not to use an out-of-state laboratory offering contracts or conditions that it could not legally offer if it were located in California. PMID:14165875

    Test results from clinical laboratories must ensure accuracy, as these are crucial in several areas of health care. It is necessary that the laboratory implements quality assurance to achieve this goal. The implementation of quality should be audited by independent bodies,referred to as accreditation bodies. Accreditation is a third-party attestation by an authoritative body, which certifies that the applicant laboratory meets quality requirements of accreditation body and has demonstrated its competence to carry out specific tasks. Although in most of the countries,accreditation is mandatory, in India it is voluntary. The quality requirements are described in standards developed by many accreditation organizations. The internationally acceptable standard for clinical laboratories is ISO15189, which is based on ISO/IEC standard 17025. The accreditation body in India is the National Accreditation Board for Testing and Calibration Laboratories, which has signed Mutual Recognition Agreement with the regional cooperation the Asia Pacific Laboratory Accreditation Cooperation and with the apex cooperation the International Laboratory Accreditation Cooperation.

    In this study, professional impact is defined as the academic literature that is cited in the literature that is used by professions in order to pursue skilled activities that are specific to their expertise. Specifically, we are focusing on the clinical guidelines that are used in the many health and medical professions that are issued by government bodies at national and international levels to ensure a certain quality level and to make results comparable at the national level. To date, more than 50.000 references have been identified in about 500 Swedish clinical guidelines issued by the above mentioned governmental bodies in Sweden. Of these, 73 % of the references have been matched to a PubMed id. The goal of this project is to develop a conceptual and theoretical contribution to the development of indicators for measuring the impact of research outside of the specifically academic literature.

    American hospitals are increasingly turning to service outsourcing to reduce costs, including laboratory services. Studies of this practice have largely focused on nonacademic medical centers. In contrast, academic medical centers have unique practice environments and unique mission considerations. We sought to elucidate and analyze clinical laboratory outsourcing experiences in US academic medical centers. Seventeen chairs of pathology with relevant experience were willing to participate in in-depth interviews about their experiences. Anticipated financial benefits from joint venture arrangements often eroded after the initial years of the agreement, due to increased test pricing, management fees, duplication of services in support of inpatients, and lack of incentive for utilization control on the part of the for-profit partner. Outsourcing can preclude development of lucrative outreach programs; such programs were successfully launched in several cases after joint ventures were either avoided or terminated. Common complaints included poor test turnaround time and problems with test quality (especially in molecular pathology, microbiology, and flow cytometry), leading to clinician dissatisfaction. Joint ventures adversely affected retention of academically oriented clinical pathology faculty, with adverse effects on research and education, which further exacerbated clinician dissatisfaction due to lack of available consultative expertise. Resident education in pathology and in other disciplines (especially infectious disease) suffered both from lack of on-site laboratory capabilities and from lack of teaching faculty. Most joint ventures were initiated with little or no input from pathology leadership, and input from pathology leadership was seen to have been critical in those cases where such arrangements were declined or terminated.

    How mental illnesses are defined has significant ramifications, given the substantial social and individual repercussions of these conditions. Using actor-network theory, I analyze how mental health professionals use the Diagnostic and Statistical Manual of Mental Disorders (DSM) in their work. Drawing on observations of a neuropsychological laboratory and interviews with 27 professionals (i.e., psychiatrists, psychologists), I investigate how the DSM is used in research, clinical, and institutional work. In research, the DSM influences study design and exclusion/inclusion criteria. In the clinic, the DSM influences how disorders are conceptualized and diagnosed. Institutionally, the DSM aligns the patient-professional encounter to insurance and pharmaceutical interests. I conclude that the DSM operates as multiple, context-specific taxonomies that pervasively influence professional practices, such that all possible actions must orient to DSM criteria, with professionals both a source and an object of institutionalized gaze. © American Sociological Association 2016.

    To characterize nationwide variation and factors associated with clinical laboratories': (1) capabilities to send structured test results electronically to ordering practitioners' EHR systems; and (2) their levels of exchange activity, as measured by whether they sent more than three-quarters of their test results as structured data to ordering practitioners' EHR systems. A national survey of all independent and hospital laboratories was conducted in 2013. Using an analytic weighted sample of 9382 clinical laboratories, a series of logistic regression analyses were conducted to identify organizational and area characteristics associated with clinical laboratories' exchange capability and activity. Hospital-based clinical laboratories (71%) and larger clinical laboratories (80%) had significantly higher levels of capability compared to independent (58%) and smaller laboratories (48%), respectively; though all had similar levels of exchange activity, with 30% of clinical laboratories sending 75% or more of their test results electronically. In multivariate analyses, hospital and the largest laboratories had 1.87 and 4.40 higher odds, respectively, of possessing the capability to send results electronically compared to independent laboratories (pLaboratories located in areas with a higher share of potential exchange partners had a small but significantly greater capability to send results electronically and higher levels of exchange activity(pClinical laboratories' capability to exchange varied by size and type; however, all clinical laboratories had relatively low levels of exchange activity. The role of exchange partners potentially played a small but significant role in driving exchange capability and activity. Published by Elsevier B.V.

    This chapter describes the need for Detailed Clinical Models for contemporary Electronic Health Systems, data exchange and data reuse. It starts with an explanation of the components related to Detailed Clinical Models with a brief summary of knowledge representation, including terminologies representing clinic relevant "things" in the real world, and information models that abstract these in order to let computers process data about these things. Next, Detailed Clinical Models are defined and their purpose is described. It builds on existing developments around the world and accumulates in current work to create a technical specification at the level of the International Standards Organization. The core components of properly expressed Detailed Clinical Models are illustrated, including clinical knowledge and context, data element specification, code bindings to terminologies and meta-information about authors, versioning among others. Detailed Clinical Models to date are heavily based on user requirements and specify the conceptual and logical levels of modelling. It is not precise enough for specific implementations, which requires an additional step. However, this allows Detailed Clinical Models to serve as specifications for many different kinds of implementations. Examples of Detailed Clinical Models are presented both in text and in Unified Modelling Language. Detailed Clinical Models can be positioned in health information architectures, where they serve at the most detailed granular level. The chapter ends with examples of projects that create and deploy Detailed Clinical Models. All have in common that they can often reuse materials from earlier projects, and that strict governance of these models is essential to use them safely in health care information and communication technology. Clinical validation is one point of such governance, and model testing another. The Plan Do Check Act cycle can be applied for governance of Detailed Clinical Models

    1998-10-01

    During the 20th century, at least until the 1980s, clinical laboratory practice had been rapidly expanded, mainly because of a significant advancement in medicine as a whole and also in laboratory technology. However, recent economic changes in health care environment worldwide have been influencing greatly future trends in clinical laboratory practice. Four major macroeconomic forces drive change in clinical laboratory practice as follows; (1) Increasing cost of health care, (2) Implications of an aging population, (3) Social change in the patient population, and (4) Explosion of new technologies. Obviously, the increasing cost of health care is the primary driver. Considering a rapid change in the health care environment, clearly there are two separate pathways to be considered with regard to future modes of delivering patient care services through the clinical laboratory: commercial independent laboratories and hospital laboratories. In most hospital laboratories, in addition to high-quality, accurate and precise laboratory data being delivered through automated informatics in a timely fashion, laboratory physicians and other laboratorians should be available 24 hours a day and 7 days a week. The primary purpose of this approach is to develop a system in which the physician can order the most efficient number of tests, which will provide the maximum amount of clinically relevant informations most rapidly and most accurately at the least cost to the patient. Laboratory physicians must play a key role particularly in hospital laboratories. Their most important roles include those of a professional supplier of laboratory results being useful for health care and clinically relevant, and that of a consultative role for primary care physicians and other co-medical staffs to make important medical decision, based on laboratory results obtained. Therefore, the Japan Society of Clinical Pathology started in 1990 in publishing a series of proposed guidelines for adequate

    In recent decades a new profession has developed--clinical criminology. The purpose of this article is to highlight its development. Criminology is defined as a interdisciplinary super-profession. We tend to view criminology as a basic profession with a number of specializations. Clinical criminology is one of these specializations. Forensic psychiatry and clinical criminology have common roots in psychiatry, law and behavioural sciences. They overlap in some fields. Members of both professions work in the same setting and share some of the tasks, but the formal and professional responsibilities differ significantly. We perceive clinical criminology and forensic psychiatry as complementary professions belonging to medicine. The multidisciplinary educated clinical criminologist is the only professional in the forensic system who is qualified to moderate between the mental health and legal expert.

    Imagine a clinical microbiology laboratory where a patient's specimens are placed on a conveyor belt and sent on an automation line for processing and plating. Technologists need only log onto a computer to visualize the images of a culture and send to a mass spectrometer for identification. Once a pathogen is identified, the system knows to send the colony for susceptibility testing. This is the future of the clinical microbiology laboratory. This article outlines the operational and staffing challenges facing clinical microbiology laboratories and the evolution of automation that is shaping the way laboratory medicine will be practiced in the future.

  4. Errors in clinical laboratories or errors in laboratory medicine?

    Science.gov (United States)

    Plebani, Mario

    2006-01-01

    Laboratory testing is a highly complex process and, although laboratory services are relatively safe, they are not as safe as they could or should be. Clinical laboratories have long focused their attention on quality control methods and quality assessment programs dealing with analytical aspects of testing. However, a growing body of evidence accumulated in recent decades demonstrates that quality in clinical laboratories cannot be assured by merely focusing on purely analytical aspects. The more recent surveys on errors in laboratory medicine conclude that in the delivery of laboratory testing, mistakes occur more frequently before (pre-analytical) and after (post-analytical) the test has been performed. Most errors are due to pre-analytical factors (46-68.2% of total errors), while a high error rate (18.5-47% of total errors) has also been found in the post-analytical phase. Errors due to analytical problems have been significantly reduced over time, but there is evidence that, particularly for immunoassays, interference may have a serious impact on patients. A description of the most frequent and risky pre-, intra- and post-analytical errors and advice on practical steps for measuring and reducing the risk of errors is therefore given in the present paper. Many mistakes in the Total Testing Process are called "laboratory errors", although these may be due to poor communication, action taken by others involved in the testing process (e.g., physicians, nurses and phlebotomists), or poorly designed processes, all of which are beyond the laboratory's control. Likewise, there is evidence that laboratory information is only partially utilized. A recent document from the International Organization for Standardization (ISO) recommends a new, broader definition of the term "laboratory error" and a classification of errors according to different criteria. In a modern approach to total quality, centered on patients' needs and satisfaction, the risk of errors and mistakes

    Laboratory automation proposes to improve the quality and efficiency of laboratory operations, and may provide a solution to the quality demands and staff shortages faced by today's clinical laboratories. Several vendors offer automation systems in the United States, with both subtle and obvious differences. Arriving at a decision to automate, and the ensuing evaluation of available products, can be time-consuming and challenging. Although considerable discussion concerning the decision to automate has been published, relatively little attention has been paid to the process of evaluating and selecting automation systems. To outline a process for evaluating and selecting automation systems as a reference for laboratories contemplating laboratory automation. Our Clinical Chemistry Laboratory staff recently evaluated all major laboratory automation systems in the United States, with their respective chemistry and immunochemistry analyzers. Our experience is described and organized according to the selection process, the important considerations in clinical chemistry automation, decisions and implementation, and we give conclusions pertaining to this experience. Including the formation of a committee, workflow analysis, submitting a request for proposal, site visits, and making a final decision, the process of selecting chemistry automation took approximately 14 months. We outline important considerations in automation design, preanalytical processing, analyzer selection, postanalytical storage, and data management. Selecting clinical chemistry laboratory automation is a complex, time-consuming process. Laboratories considering laboratory automation may benefit from the concise overview and narrative and tabular suggestions provided.

    2013-01-01

    Hemostasis is a delicate, dynamic and intricate system, in which pro- and anti-coagulant forces cooperate for either maintaining blood fluidity under normal conditions, or else will prompt blood clot generation to limit the bleeding when the integrity of blood vessels is jeopardized. Excessive prevalence of anticoagulant forces leads to hemorrhage, whereas excessive activation of procoagulant forces triggers excessive coagulation and thrombosis. The hemostasis laboratory performs a variety of first, second and third line tests, and plays a pivotal role in diagnostic and monitoring of most hemostasis disturbances. Since the leading targets of Clinical Chemistry and Laboratory Medicine include promotion of progress in fundamental and applied research, along with publication of guidelines and recommendations in laboratory diagnostics, this journal is an ideal source of information on current developments in the laboratory technology of hemostasis, and this article is aimed to celebrate some of the most important and popular articles ever published by the journal in the filed of laboratory hemostasis.

    Conclusion: Most laboratory technicians in our study reported favourable perceptions of CME programmes, feeling that they increased professional confidence and competency. We recommend that core competencies be integrated into credentialing using profession-specific CME in a workplace setting. In addition, MLTs should be involved in designing the programmes as well. Further studies in a multicentre institution are needed to analyse the difference in perception among those who have attended CME and those who have not.

  8. Adding value to laboratory medicine: a professional responsibility.

    Science.gov (United States)

    Beastall, Graham H

    2013-01-01

    Laboratory medicine is a medical specialty at the centre of healthcare. When used optimally laboratory medicine generates knowledge that can facilitate patient safety, improve patient outcomes, shorten patient journeys and lead to more cost-effective healthcare. Optimal use of laboratory medicine relies on dynamic and authoritative leadership outside as well as inside the laboratory. The first responsibility of the head of a clinical laboratory is to ensure the provision of a high quality service across a wide range of parameters culminating in laboratory accreditation against an international standard, such as ISO 15189. From that essential baseline the leadership of laboratory medicine at local, national and international level needs to 'add value' to ensure the optimal delivery, use, development and evaluation of the services provided for individuals and for groups of patients. A convenient tool to illustrate added value is use of the mnemonic 'SCIENCE'. This tool allows added value to be considered in seven domains: standardisation and harmonisation; clinical effectiveness; innovation; evidence-based practice; novel applications; cost-effectiveness; and education of others. The assessment of added value in laboratory medicine may be considered against a framework that comprises three dimensions: operational efficiency; patient management; and patient behaviours. The profession and the patient will benefit from sharing examples of adding value to laboratory medicine.

    2015-01-01

    The purpose of this paper is to illustrate a service quality framework that enhances service delivery in clinical laboratories by gauging medical practitioner satisfaction and by providing avenues for continuous improvement. The case study method has been used for conducting the exploratory study, with focus on the Mauritian public clinical laboratory. A structured questionnaire based on the SERVQUAL service quality model was used for data collection, analysis and for the development of the service quality framework. The study confirms the pertinence of the following service quality dimensions within the context of clinical laboratories: tangibility, reliability, responsiveness, turnaround time, technology, test reports, communication and laboratory staff attitude and behaviour. The service quality framework developed, termed LabSERV, is vital for clinical laboratories in the search for improving service delivery to medical practitioners. This is a pioneering work carried out in the clinical laboratory sector in Mauritius. Medical practitioner expectations and perceptions have been simultaneously considered to generate a novel service quality framework for clinical laboratories.

    Email is one of the most widely used methods of communication, but its use in healthcare is still uncommon. Where email communication has been utilised in health care, its purposes have included clinical communication between healthcare professionals, but the effects of using email in this way are not well known. We updated a 2012 review of the use of email for two-way clinical communication between healthcare professionals. To assess the effects of email for clinical communication between healthcare professionals on healthcare professional outcomes, patient outcomes, health service performance, and service efficiency and acceptability, when compared to other forms of communicating clinical information. We searched: the Cochrane Consumers and Communication Review Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 9 2013), MEDLINE (OvidSP) (1946 to August 2013), EMBASE (OvidSP) (1974 to August 2013), PsycINFO (1967 to August 2013), CINAHL (EbscoHOST) (1982 to August 2013), and ERIC (CSA) (1965 to January 2010). We searched grey literature: theses/dissertation repositories, trials registers and Google Scholar (searched November 2013). We used additional search methods: examining reference lists and contacting authors. Randomised controlled trials, quasi-randomised trials, controlled before and after studies, and interrupted time series studies examining interventions in which healthcare professionals used email for communicating clinical information in the form of: 1) unsecured email, 2) secure email, or 3) web messaging. All healthcare professionals, patients and caregivers in all settings were considered. Two authors independently assessed studies for inclusion, assessed the included studies' risk of bias, and extracted data. We contacted study authors for additional information and have reported all measures as per the study report. The previous version of this review included one randomised controlled

    It is meaningful to discuss the "present and future of laboratories" for the development of laboratories and education of medical technologists. Laboratory staff must be able to perform urgent high-quality tests and take part in so-called team-based medicine and should be proud of devising systems that efficiently provide laboratory data for all medical staff. On the other hand, there may be staff with a poor sense of professionalism who work no more than is expected and too readily ask firms and commercial laboratories to solve problems. Overwork caused by providing team-based medicine and a decrease in numbers of clinical chemists are concerns. The following are hoped for in the future. Firstly, laboratory staff will become conscious of their own high-level abilities and expand their areas of work, for example, bioscience, proteomics, and reproductive medicine. Secondly, a consultation system for medical staff and patients will be established. Thirdly, clinical research will be advanced, such as investigating unknown pathophysiologies using laboratory data and samples, and developing new methods of measurement. Lastly, it is of overriding importance that staff of laboratory and educational facilities will cooperate with each other to train the next generation. In conclusion, each laboratory should be appreciated, attractive, positive regarding its contribution to society, and show individuality.

    Clinical laboratories in university hospitals should be operated with a good balance of medical practice, education, research, and management. The role of a clinical laboratory is to promptly provide highly reliable laboratory data to satisfy the needs of clinicians involved in medical practice and health maintenance of patients. Improvement and maintenance of the quality of the laboratory staff and environment are essential to achieve this goal. In order to implement these requirements efficiently, an appropriate quality management system should be introduced and established, and evaluated objectively by a third party (e.g. by obtaining ISO 15189 certification). ISO 15189 is an international standard regarding the quality and competence of clinical laboratories, and specifies a review of the efficient operational system and technical requirements such as competence in implementing practical tests and calibration. This means the results of laboratory tests reported by accredited laboratories withstand any international evaluation, which is very important to assure the future importance of the existence and management of clinical laboratories as well as internationalization of medical practice. "Education" and "research" have important implications in addition to "medical practice" and "management", as the roles that clinical laboratories should play in university hospitals. University hospital laboratories should be operated by keeping these four factors in good balance. Why are "education" and "research" required in addition to "medical practice" services? If individual clinical laboratory technologists can provide an appropriate response to this question, the importance of the existence of clinical laboratories would be reinforced, without being compromised.

  15. Clinical laboratory billing: superfluous requirements without justification?

    Science.gov (United States)

    Stadler, Stephen

    2004-01-01

    Congress occasionally passes new laws that affect how clinical laboratories handle test orders from physicians and, subsequently, process the billing for tests. Once a bill is signed into law, it is forwarded to administrative agencies, which draft regulations and administrative procedures, under which the intentions of Congress are carried out. In the case of laboratory test ordering and billing, the Centers for Medicare and Medicaid Services (CMS) has the greatest influence over how these regulations and procedures are defined. Unfortunately, in many cases, billing rules have been promulgated in ways that create the need for hospitals and commercial laboratories to expend huge sums of money to bill within the confines of the administrative rules; cause clinical laboratories to suffer from omissions and mistakes of other parties who are part of the patient care process but are not accountable for the billing information they provide to laboratories; and, frankly, in some respects, simply defy common sense.

    Clinical skills laboratories have been established in medical institutions as facilities for simulation-based medical education (SBME). SBME is believed to be superior to the traditional style of medical education from the viewpoint of the active and adult learning theories. SBME can provide a learning cycle of debriefing and feedback for learners as well as evaluation of procedures and competency. SBME offers both learners and patients a safe environment for practice and error. In a full-environment simulation, learners can obtain not only technical skills but also non-technical skills, such as leadership, team work, communication, situation awareness, decision-making, and awareness of personal limitations. SBME is also effective for integration of clinical medicine and basic medicine. In addition, technology-enhanced simulation training is associated with beneficial effects for outcomes of knowledge, skills, behaviors, and patient-related outcomes. To perform SBME, effectively, not only simulators including high-fidelity mannequin-type simulators or virtual-reality simulators but also full-time faculties and instructors as professionals of SBME are essential in a clinical skills laboratory for SBME. Clinical skills laboratory is expected to become an integrated medical education center to achieve continuing professional development, integrated learning of basic and clinical medicine, and citizens' participation and cooperation in medical education.

    2015-07-01

    Despite an increasing focus on simulation as a learning strategy in nursing education, there is limited evidence on the transfer of simulated skills into clinical practice. Therefore it's important to increase knowledge of how clinical skills laboratories (CSL) can optimize students' learning for development of professional knowledge and skills, necessary for quality nursing practice and for patient safety. Thus, the aim was to describe nursing students' experiences of learning in the CSL as a preparation for their clinical practice. Interviews with 16 students were analysed with content analysis. An overall theme was identified - walking the bridge - in which the CSL formed a bridge between the university and clinical settings, allowing students to integrate theory and practice and develop a reflective stance. The theme was based on categories: conditions for learning, strategies for learning, tension between learning in the skills laboratory and clinical settings, and development of professional and personal competence. The CSL prepared the students for clinical practice, but a negative tension between learning in CSL and clinical settings was experienced. However, this tension may create reflection. This provides a new perspective that can be used as a pedagogical approach to create opportunities for students to develop their critical thinking. Copyright © 2015 Elsevier Ltd.

    2012-06-01

    Clinical laboratories are significant generators of infectious waste, including microbiological materials, contaminated sharps, and pathologic wastes such as blood specimens and blood products. Most waste produced in laboratories can be disposed of in the general solid waste stream. However, improper management of infectious waste, including mixing general wastes with infectious wastes and improper handling or storage, could lead to disease transmission. The aim of this study was to assess waste management processes used at clinical laboratories in Shiraz, Iran. One hundred and nine clinical laboratories participated In this cross sectional study, Data collection was by questionnaire and direct observation. Of the total amount of waste generated, 52% (by weight) was noninfectious domestic waste, 43% was non-sharps infectious waste and 5% consisted of sharps. There was no significant relationship between laboratory staff or manager education and the score for quality of waste collection and disposal at clinical laboratories. Improvements in infectious waste management processes should involve clearer, more uniformly accepted definitions of infectious waste and increased staff training.

    2011-04-01

    Clinical laboratories provide an invaluable service to millions of people around the world in the form of quality diagnostic care. Within the clinical laboratory industry the impetus for change has come from technological development (miniaturization, nanotechnology, and their collective effect on point-of-care testing; POCT) and the increasingly global nature of laboratory services. Potential technological gains in POCT include: the development of bio-sensors, microarrays, genetics and proteomics testing, and enhanced web connectivity. In globalization, prospective opportunities lie in: medical tourism, the migration of healthcare workers, cross-border delivery of testing, and the establishment of accredited laboratories in previously unexplored markets. Accompanying these impressive opportunities are equally imposing challenges. Difficulty transitioning from research to clinical use, poor infrastructure in developing countries, cultural differences and national barriers to global trade are only a few examples. Dealing with the issues presented by globalization and the impact of developing technology on POCT, and on the clinical laboratory services industry in general, will be a daunting task. Despite such concerns, with appropriate countermeasures it will be possible to address the challenges posed. Future laboratory success will be largely dependent on one's ability to adapt in this perpetually shifting landscape.

  20. Selecting clinical quality indicators for laboratory medicine.

    Science.gov (United States)

    Barth, Julian H

    2012-05-01

    Quality in laboratory medicine is often described as doing the right test at the right time for the right person. Laboratory processes currently operate under the oversight of an accreditation body which gives confidence that the process is good. However, there are aspects of quality that are not measured by these processes. These are largely focused on ensuring that the most clinically appropriate test is performed and interpreted correctly. Clinical quality indicators were selected through a two-phase process. Firstly, a series of focus groups of clinical scientists were held with the aim of developing a list of quality indicators. These were subsequently ranked in order by an expert panel of primary and secondary care physicians. The 10 top indicators included the communication of critical results, comprehensive education to all users and adequate quality assurance for point-of-care testing. Laboratories should ensure their tests are used to national standards, that they have clinical utility, are calibrated to national standards and have long-term stability for chronic disease management. Laboratories should have error logs and demonstrate evidence of measures introduced to reduce chances of similar future errors. Laboratories should make a formal scientific evaluation of analytical quality. This paper describes the process of selection of quality indicators for laboratory medicine that have been validated sequentially by deliverers and users of the service. They now need to be converted into measureable variables related to outcome and validated in practice.

  1. The changing face of clinical laboratories.

    1999-07-01

    Laboratory medicine has undergone a sea change, and medical laboratories must now adapt to, and meet new, customer-supplier needs springing from shifts in the patterns of disease prevalence, medical practice, and demographics. Managed care and other cost-containment processes have forced those involved in health care to cooperate to develop a full picture of patient care, and this has affected clinical laboratory objectives, the main focus now being on improvement in medical outcomes. More recently, the resource shortages in health care and results of cost/effectiveness analysis have demonstrated that the value of a laboratory test must be ascertained not only on the basis of its chemical or clinical performance characteristics, but also by its impact on patient management, the only true assessment of the quality of testing being quality of patient outcomes. The time is ripe for changing the vision of laboratory medicine, and some of the reasons for this are the availability of results in real-time, the introduction of more specific tests, and the trend to prevent diseases rather than cure them. The information from laboratory tests designed to evaluate biochemical or genetic risk and/or prognostic factors cannot be replaced either by physical examination and/or the assessment of symptoms. Today, the importance of laboratory scientists must be proven in three broad areas: a) guaranteeing the quality of tests, irrespective of where they are performed; b) improving the quality of the service; c) maximizing the impact of laboratory information on patient management.

  2. Clinical laboratory: bigger is not always better.

    2018-06-27

    Laboratory services around the world are undergoing substantial consolidation and changes through mechanisms ranging from mergers, acquisitions and outsourcing, primarily based on expectations to improve efficiency, increasing volumes and reducing the cost per test. However, the relationship between volume and costs is not linear and numerous variables influence the end cost per test. In particular, the relationship between volumes and costs does not span the entire platter of clinical laboratories: high costs are associated with low volumes up to a threshold of 1 million test per year. Over this threshold, there is no linear association between volumes and costs, as laboratory organization rather than test volume more significantly affects the final costs. Currently, data on laboratory errors and associated diagnostic errors and risk for patient harm emphasize the need for a paradigmatic shift: from a focus on volumes and efficiency to a patient-centered vision restoring the nature of laboratory services as an integral part of the diagnostic and therapy process. Process and outcome quality indicators are effective tools to measure and improve laboratory services, by stimulating a competition based on intra- and extra-analytical performance specifications, intermediate outcomes and customer satisfaction. Rather than competing with economic value, clinical laboratories should adopt a strategy based on a set of harmonized quality indicators and performance specifications, active laboratory stewardship, and improved patient safety.

    This article describes information systems as a quality management tool in clinical laboratories. The quality of laboratory analyses is of fundamental importance for health professionals in aiding appropriate diagnosis and treatment. Information systems allow the automation of internal quality management processes, using standard sample tests, Levey-Jennings charts and Westgard multirule analysis. This simplifies evaluation and interpretation of quality tests and reduces the possibility of human error. This study proposes the development of an information system with appropriate functions and costs for the automation of internal quality control in small and medium-sized clinical laboratories. To this end, it evaluates the functions and usability of two commercial software products designed for this purpose, identifying the positive features of each, so that these can be taken into account during the development of the proposed system.

    Full Text Available Negotiation as a skill is a key requirement for each and every job profile where dealing with multiple parties is involved. The important focus while negotiating should be on the interest then position. Key to every successful negotiation is advance planning, preparation, and patience as the objective is to create value and establish the terms on which parties with differing and often conflicting aims will co-operate. While preparing one should collect facts, know priorities, principles, identify common ground, decide on walk-away position, and try and identify the next best alternative. Negotiation is a set of skills that can be learned and practiced so that your ability to utilize relationship, knowledge, money, power, time, and personality to negotiate improves with each negotiation. In a successful negotiation, all parties win. Important thing to note is that not every negotiation involves money. Anytime you want something from someone else and anytime someone wants something from you, you are negotiating. Everything is negotiable and every day you negotiate with customers, suppliers, colleagues, your wife, and even your children. Negotiation is a game, and like any game it has its rules and tactics. Clinical Research professionals deal with various parties for different purposes at the same time; hence, they require excellent negotiation skills. Project Mangers and Clinical Research Associates are the two most important roles in clinical research industry who require negotiation skills as they deal with various internal and external customers and vendors.

    Ashkar, F.S.; Fishman, L.M.

    1983-01-01

    Because of their special physical and chemical properties, the adrenal secretory products were among the first hormonal substances to be measured by methods other than bioassay. Over the past several years, the development of sensitive and specific methods of hormone assay dependent on the use of radionuclides has revolutionized investigative and clinical endocrinology. While the capacity of defining most abnormalities of adrenal function antedates hormone measurement and adrenal imaging utilizing radioisotopes, the availability of such methods has greatly facilitated and made more precise the diagnostic approach to patients with suspected adrenal dysfunction. As an example of how clinical and laboratory considerations can be integrated into a rational approach to the diagnosis of adrenal disease, the problem of suspected adrenal hyperfunction is analyzed in light of current understanding of its pathophysiology. Reflection demonstrates that suspected primary aldosteronism and adrenal insufficiency are equally amenable to such an approach

    The healthcare sector is an important contributor to mercury (Hg) pollution because of the potential presence of mercury in thermometers, blood pressure cuffs, amalgams, etc. There are also other potential sources of mercury in this sector which are used frequently and in high volumes where the presence of the metal is not obvious and which might be collectively contributing to pollution. For instance, some chemicals used for the clinical diagnosis of illness may contain mercury. The goal of this study was to investigate potential sources of mercury pollution, which originate from clinical laboratory discharges, using an exploratory approach. The focus was on the residue generated during automatic analysis of patients' bodily fluids at a medical center in Hermosillo, Sonora, Mexico. This study shows an overview of what might be happening in the region or the country related to non-obvious sources of mercury in the healthcare sector. The results showed measurable levels of mercury in the residues coming from urine sediment analysis. These amounts do not exceed the maximum allowed by Mexican environmental regulations; nevertheless, the frequency and cumulative volume of residues generated, combined with the potential for persistence and the bioaccumulation of mercury in the environment, warrant attention. The work carried out in this study is being taken as a model for future studies for pollution prevention in the healthcare sector with the goal of measuring mercury emissions to the environment from clinical laboratory wastewater, including identifying sources which--while not obvious--could be important given the frequency and volume of their use in the clinical diagnosis.

    Full Text Available OBJECTIVE: To evaluate clinically, and with laboratory, tests, women with polycystic ovary syndrome (PCO. PATIENTS: One hundred and twelve women with PCO were studied. METHODS: The following data was recorded: Current age; age at menarche; menstrual irregularity, occurrence of similar cases in the family; fertility, obstetric history; body mass index (BMI; and presence of hirsutism. Serum measurements of follicle stimulating hormone (FSH, luteinizing hormone (LH, prolactin, free testosterone, and dehydroepiandrosterone sulfate were taken. RESULTS: All patients presented either oligomenorrhea (31 percent, periods of secondary amenorrhea (9 percent, or both alterations (60 percent. The majority of the patients were infertile (75.6 percent. The LH/FSH ratio was higher than 2:1 in 55 percent of the patients and higher than 3:1 in 26.2 percent. The ultrasonographic aspect of the ovaries was considered to be normal in 31 percent. CONCLUSION: The main clinical feature of the PCO is the irregularity of menses since menarche, and that the laboratory tests would be important to exclude other disorders such as hyperprolactinemia or hyperandrogenemia caused by late-onset congenital adrenal hyperplasia.

    Laboratory professionals are expected to maintain their knowledge on the most recent advances in laboratory testing and continuing professional development (CPD) programs can address this expectation. In developing countries, accessing CPD programs is a major challenge for laboratory personnel, partly due to their limited availability. An assessment was conducted among clinical laboratory workforce in Botswana to identify and prioritize CPD training needs as well as preferred modes of CPD delivery. A self-administered questionnaire was disseminated to medical laboratory scientists and technicians registered with the Botswana Health Professions Council. Questions were organized into domains of competency related to (i) quality management systems, (ii) technical competence, (iii) laboratory management, leadership, and coaching, and (iv) pathophysiology, data interpretation, and research. Participants were asked to rank their self-perceived training needs using a 3-point scale in order of importance (most, moderate, and least). Furthermore, participants were asked to select any three preferences for delivery formats for the CPD. Out of 350 questionnaires that were distributed, 275 were completed and returned giving an overall response rate of 79%. The most frequently selected topics for training in rank order according to key themes were (mean, range) (i) quality management systems, most important (79%, 74-84%); (ii) pathophysiology, data interpretation, and research (68%, 52-78%); (iii) technical competence (65%, 44-73%); and (iv) laboratory management, leadership, and coaching (60%, 37-77%). The top three topics selected by the participants were (i) quality systems essentials for medical laboratory, (ii) implementing a quality management system, and (iii) techniques to identify and control sources of error in laboratory procedures. The top three preferred CPD delivery modes, in rank order, were training workshops, hands-on workshops, and internet-based learning

    Full Text Available The clinical laboratory is a major source of health care data. Increasingly these data are being integrated with other data to inform health system-wide actions meant to improve diagnostic test utilization, service efficiency, and "meaningful use." The Academy of Clinical Laboratory Physicians and Scientists hosted a satellite meeting on clinical laboratory analytics in conjunction with their annual meeting on May 29, 2014 in San Francisco. There were 80 registrants for the clinical laboratory analytics meeting. The meeting featured short presentations on current trends in clinical laboratory analytics and several panel discussions on data science in laboratory medicine, laboratory data and its role in the larger healthcare system, integrating laboratory analytics, and data sharing for collaborative analytics. One main goal of meeting was to have an open forum of leaders that work with the "big data" clinical laboratories produce. This article summarizes the proceedings of the meeting and content discussed.

    Haemolysis is usually caused by inadequate specimen collection or preanalytical handling and is suggested to be a suitable indicator of preanalytical quality. We investigated the prevalence of detectable haemolysis in all routine venous blood samples in OPDs and IPDs to identify differences in preanalytical quality. Haemolysis index (HI) values were obtained from a Vitros 5,1 in the routine clinical chemistry laboratory for samples collected in the outpatient department (OPD) collection centres, a hospital, and inpatient departments (IPD). Haemolysis was defined as a HI > or = 15 (detection limit). Samples from the OPD with the highest prevalence of haemolysis were 6.1 times (95% confidence interval (CI) 4.0 - 9.2) more often haemolysed compared to the center with the lowest prevalence. Of the samples collected in primary health care, 10.4% were haemolysed compared to 31.1% in the IPDs (p = 0.001). A notable difference in haemolysed samples was found between the IPDs section staffed by emergency medicine physicians and the section staffed by primary health care physicians (34.8% vs. 11.3%, p = 0.001). The significant variation in haemolysis indices among the investigated units is likely to reflect varying preanalytical conditions. The HI is a valuable tool for estimation and follow-up of preanalytical quality in the health care laboratory.

    In the clinical-chemical laboratory, the problems of the personal radiation protection can be handled relatively simply. Important conditions are certain requirements as far as the building is concerned and the keeping to protection measures to invoid ingestion, inhalation, and resorption of open radioactive substances. Very intensive attention must be paid to a clean working technique in order to be able to exclude the danger of contamination which is very disturbing during the extremely sensitive measurements. The higgest problem in the handling of open radioactive substances, however, is in our opinion the waste management because it requires which space and personnel this causing high costs. Furthermore, since 1 January 1979, the permission for the final storage of radioactive waste in the shut down mine ASSE was taken back from the county collection places and it cannot be said yet if and when this permission will be given again.

    Opposite to clinical laboratory findings in experimental drowning of animals (erythrocytic lysis, hyperkalemia, and final cardial fibrillation) are the observations in drowned humans (increase of pCO2, hypoxic encephalopathy), which leads to a different pathophysiological interpretation of the drowning process. This process, however, is recently discussed again, therefore an additional study seemed to be recommended. In a retrospective study, 31 cases of near-drowning (23 cases: fresh water; 8 cases: brackish water) clinical laboratory data were analysed. While 21 of the cases were fatal with a delay of up to 180 days, 10 individuals survived the accident, four cases with severe neurological deficits. Data of pH, potassium, sodium, chloride, hemoglobin and total protein were collected during the very early post-drowning period. Nearly all cases (96%) revealed a reduction of pH due to hypoxic acidosis, and only two cases (6.5%) exhibited a slight hyperkalemia. The hemoglobin level was normal in most of the cases (83%) and slightly reduced in the others (17%) while the protein level was slightly reduced in most of the fatalities (80%). As a result of our investigation we have to state the lack of hyperkalemia as well as of an increase of the hemoglobin level indicate that there is no distinct intravascular red cell lysis due to influx of water into the vascular compartment. Therefore the death by drowning in humans in most cases is the result of a hypoxic cerebral process. A comparison with animal experiments obviously is not helpful because the drowning process in humans leads to an aspiration of only 2-4 ml water/kg, while in animal experiments more than 10 ml water/kg will be artificially aspirated leading to red cell lysis as well as to electrolyte disturbances and cardial fibrillation.

The clinical laboratory science profession continues to suffer from a lack of knowledge about the field by the general public, college advisors, and even healthcare workers. State and national programs involving grants/scholarships or loan forgiveness programs offered by healthcare institutions would be beneficial in attracting students to study the clinical laboratory sciences.

    2005-06-01

    Since the winter of 1999, the authors and their research team have been conducting clinical studies involving the administration of ayahuasca to healthy volunteers. The rationale for conducting this kind of research is twofold. First, the growing interest of many individuals for traditional indigenous practices involving the ingestion of natural psychotropic drugs such as ayahuasca demands the systematic study of their pharmacological profiles in the target species, i.e., human beings. The complex nature of ayahuasca brews combining a large number of pharmacologically active compounds requires that research be carried out to establish the safety and overall pharmacological profile of these products. Second, the authors believe that the study of psychedelics in general calls for renewed attention. Although the molecular and electrophysiological level effects of these drugs are relatively well characterized, current knowledge of the mechanisms by which these compounds modify the higher order cognitive processes in the way they do is still incomplete, to say the least. The present article describes the development of the research effort carried out at the Autonomous University of Barcelona, commenting on several methodological aspects and reviewing the basic clinical findings. It also describes the research currently underway in our laboratory, and briefly comments on two new studies we plan to undertake in order to further our knowledge of the pharmacology of ayahuasca.

    Laboratory-acquired infections due to nontyphoidal Salmonella are rare. Yet, recent outbreaks in microbiology teaching laboratories show that these species are still an appreciable occupational hazard for laboratory employees. This article presents two cases of nontyphoidal Salmonella that occurred at the authors' institution—an infected patient and a clinical laboratory worker who acquired the infection by handling this patient's specimens.

    Thorough review of current workload, staffing, and testing practices in clinical laboratories allows for optimization of laboratory efficiency and quality. This information is largely missing with regard to clinical flow cytometry laboratories. The purpose of this survey is to provide comprehensive, current, and accurate data on testing practices and laboratory staffing in clinical laboratories performing flow cytometric studies. Survey data was collected from flow cytometry laboratories through the ASCP website. Data was collected on the workload during a 1-year time period of full-time and part-time technical and professional (M.D./D.O./Ph.D. or equivalent) flow cytometry employees. Workload was examined as number of specimens and tubes per full time equivalent (FTE) technical and professional staff. Test complexity, test result interpretation, and reporting practices were also evaluated. There were 205 respondent laboratories affiliated predominantly with academic and health system institutions. Overall, 1,132 FTE employees were reported with 29% professional FTE employees and 71% technical. Fifty-one percent of the testing performed was considered high complexity and 49% was low complexity. The average number of tubes per FTE technologist was 1,194 per year and the average number of specimens per FTE professional was 1,659 per year. The flow cytometry reports were predominantly written by pathologists (57%) and were typically written as a separate report (58%). This survey evaluates the overall status of the current practice of clinical flow cytometry and provides a comprehensive dataset as a framework to help laboratory departments, directors, and managers make appropriate, cost-effective staffing decisions. © 2016 International Clinical Cytometry Society. © 2016 International Clinical Cytometry Society.

    2015-01-01

    The purpose of this paper is to investigate how clinicians' professional background influences their transition into the managerial role and identity as clinical managers. The authors interviewed and observed 30 clinicians in managerial positions in Norwegian hospitals. A central finding was that doctors experienced difficulties in reconciling the role as health professional with the role as manager. They maintained a health professional identity and reported to find meaning and satisfaction from clinical work. Doctors also emphasized clinical work as a way of gaining legitimacy and respect from medical colleagues. Nurses recounted a faster and more positive transition into the manager role, and were more fully engaged in the managerial aspects of the role. The authors advance that health care organizations need to focus on role, identity and need satisfaction when recruiting and developing clinicians to become clinical managers. The study suggests that the inclusion of aspects from identity and need satisfaction literature expands on and enriches the study of clinical managers.

    To assess the present status of the clinical laboratory database management system, the difference between the Clinical Laboratory Information System and Clinical Laboratory System was explained in this study. Although three kinds of database management systems (DBMS) were shown including the relational model, tree model and network model, the relational model was found to be the best DBMS for the clinical laboratory database based on our experience and developments of some clinical laboratory expert systems. As a future clinical laboratory database management system, the IC card system connected to an automatic chemical analyzer was proposed for personal health data management and a microscope/video system was proposed for dynamic data management of leukocytes or bacteria.

    The clinical presentation of hepatocellular carcinoma (HCC differs between patients in developing countries (African and Chinese populations from those in industrialized countries. In industrialized countries, HCC co-exists with symptomatic cirrhosis in 80% of cases and clinical manifestations are usually related to those of the underlying disease. On the other hand, patients from developing countries have HCC and cirrhosis in approximately 40% of cases. Underlying cirrhosis in many cases is not advanced and does not produce any symptoms or associated symptoms are masked by those of the tumor (right upper quadrant pain, mass in the upper abdomen, weight loss and weakness. In a subset of patients, there are no clinical manifestations as HCC may occur in the context of hepatitis B infection without cirrhosis.

    Clinical Manifestations

    In Western countries, nearly 35% percent of patients with HCC are asymptomatic. Some of the most common clinical manifestations include: abdominal pain (53-58% of patients, especially in epigastrium or right upper quadrant, abdominal mass (30%, weight loss, malaise, anorexia, cachexia, jaundice or fever.

    Physical Exam

    Physical findings vary with the stage of disease. The patient may exhibit slight or moderate wasting when first seen. In patients with cirrhosis, typical stigmata of chronic liver disease may be present. In advanced stages of HCC the liver may be enlarged and there is significant tenderness. An arterial bruit may be heard over the liver

    As the 2nd Joint Symposium of the Japanese Society of Laboratory Medicine and the Japanese Association of Laboratory Pathologists, the symposium on clinical test out-sourcing and branch laboratories was held at the 60th General Meeting of the Japanese Society of Laboratory Medicine on November 2nd, 2013 in Kobe. For the symposium, we conducted a questionnaire survey on the usage of clinical test out-sourcing and the introduction of branch laboratories to clinical laboratories of Japanese university hospitals, both private and public, between July 25th and August 20th, 2013. Seventy-two hospitals responded to the questionnaire survey, consisting of 41 public medical school hospitals and 31 private ones. According to the survey, the selection of each clinical test for out-sourcing was mainly determined by the capacities of hospital clinical laboratories and their equipment, as well as the profitability of each test. The main concerns of clinical laboratory members of university hospitals involved the continuity of measurement principles, traceability, and standardization of reference values for each test. They strongly requested the interchangeability and computerization of test data between laboratory testing companies. A branch laboratory was introduced to six hospitals, all of which were private medical college hospitals, out of 72 university hospitals, and eight of the other hospitals were open to its introduction. The merits and demerits of introducing a branch laboratory were also discussed. (Review).

    The professional duties of the specialists in clinical chemistry differ from country to country in Europe. One of the main goals of the Strategic Plan of the Forum of the European Societies of Clinical Chemistry and Laboratory Medicine (FESCC; IFCC-Europe) is to promote a high scientific and professional standard in the field of clinical chemistry and laboratory medicine in Europe. This can be stimulated by the knowledge of the local conditions in each country and by striving towards a strong and harmonised position in all the European countries. In order to enhance the knowledge of the managerial situation of the specialists in clinical chemistry in Europe, FESCC launched a survey in September 2000. This survey provides information about the position of the specialists in clinical chemistry in the various disciplines in the medical laboratories and in hospitals, and about the advisory tasks and the managerial education during the post-graduate training in clinical chemistry. Of the 35 FESCC member countries 33 have participated in the survey (94%). The results show a rather heterogeneous situation in Europe caused by the local historical developments, the differences in academic background and the relative numbers of private and physicians' office laboratories. Large differences exist between the European countries in the disciplines of laboratory medicine that are headed by a specialist in clinical chemistry. In the different countries the clinical chemistry laboratories are headed by specialists in clinical chemistry in between 20% and 100% of the laboratories. The haematology, immunology, microbiology, therapeutic drug monitoring, molecular biology and haemostasis laboratories and departments of blood banking are headed by specialists in clinical chemistry in between 0% and 100% of the laboratories. The responsibilities for the various managerial tasks of the specialists in clinical chemistry show no uniformity in Europe. In the majority of the countries the

    2016-03-01

    Automation was introduced many years ago in several diagnostic disciplines such as chemistry, haematology and molecular biology. The first laboratory automation system for clinical bacteriology was released in 2006, and it rapidly proved its value by increasing productivity, allowing a continuous increase in sample volumes despite limited budgets and personnel shortages. Today, two major manufacturers, BD Kiestra and Copan, are commercializing partial or complete laboratory automation systems for bacteriology. The laboratory automation systems are rapidly evolving to provide improved hardware and software solutions to optimize laboratory efficiency. However, the complex parameters of the laboratory and automation systems must be considered to determine the best system for each given laboratory. We address several topics on laboratory automation that may help clinical bacteriologists to understand the particularities and operative modalities of the different systems. We present (a) a comparison of the engineering and technical features of the various elements composing the two different automated systems currently available, (b) the system workflows of partial and complete laboratory automation, which define the basis for laboratory reorganization required to optimize system efficiency, (c) the concept of digital imaging and telebacteriology, (d) the connectivity of laboratory automation to the laboratory information system, (e) the general advantages and disadvantages as well as the expected impacts provided by laboratory automation and (f) the laboratory data required to conduct a workflow assessment to determine the best configuration of an automated system for the laboratory activities and specificities.

    To understand the potential causes of laboratory-acquired infections and to provide possible solutions that would protect laboratory personnel, samples from a viral laboratory were screened to determine the main sources of contamination with six subtypes of Rhinovirus. Rhinovirus contamination was found in the gloves, cuffs of protective wear, inner surface of biological safety cabinet (BSC) windows, and trash handles. Remarkably, high contamination was found on the inner walls of the centrifuge and the inner surface of centrifuge tube casing in the rotor. Spilling infectious medium on the surface of centrifuge tubes was found to contribute to contamination of centrifuge surfaces. Exposure to sodium hypochlorite containing no less than 0.2 g/L available chlorine decontaminated the surface of the centrifuge tubes from Rhinovirus after 2 min.

    Fifty-five hospitals in the United States have been designated Ebola treatment centers (ETCs) by their state and local health authorities. Designated ETCs must have appropriate plans to manage a patient with confirmed Ebola virus disease (EVD) for the full duration of illness and must have these plans assessed through a CDC site visit conducted by an interdisciplinary team of subject matter experts. This study determined the clinical laboratory capabilities of these ETCs. ETCs were electronically surveyed on clinical laboratory characteristics. Survey responses were returned from 47 ETCs (85%). Forty-one (87%) of the ETCs planned to provide some laboratory support (e.g., point-of-care [POC] testing) within the room of the isolated patient. Forty-four (94%) ETCs indicated that their hospital would also provide clinical laboratory support for patient care. Twenty-two (50%) of these ETC clinical laboratories had biosafety level 3 (BSL-3) containment. Of all respondents, 34 (72%) were supported by their jurisdictional public health laboratory (PHL), all of which had available BSL-3 laboratories. Overall, 40 of 44 (91%) ETCs reported BSL-3 laboratory support via their clinical laboratory and/or PHL. This survey provided a snapshot of the laboratory support for designated U.S. ETCs. ETCs have approached high-level isolation critical care with laboratory support in close proximity to the patient room and by distributing laboratory support among laboratory resources. Experts might review safety considerations for these laboratory testing/diagnostic activities that are novel in the context of biocontainment care.

    This paper discusses a knowledge management system for clinical laboratories. In the clinical laboratory of Toranomon Hospital, we receive about 20 questions relevant to laboratory tests per day from medical doctors or co-medical staff. These questions mostly involve the essence to appropriately accomplish laboratory tests. We have to answer them carefully and suitably because an incorrect answer may cause a medical accident. Up to now, no method has been in place to achieve a rapid response and standardized answers. For this reason, the laboratory staff have responded to various questions based on their individual knowledge. We began to develop a knowledge management system to promote the knowledge of staff working for the laboratory. This system is a type of knowledge base for assisting the work, such as inquiry management, laboratory consultation, process management, and clinical support. It consists of several functions: guiding laboratory test information, managing inquiries from medical staff, reporting results of patient consultation, distributing laboratory staffs notes, and recording guidelines for laboratory medicine. The laboratory test information guide has 2,000 records of medical test information registered in the database with flexible retrieval. The inquiry management tool provides a methos to record all questions, answer easily, and retrieve cases. It helps staff to respond appropriately in a short period of time. The consulting report system treats patients' claims regarding medical tests. The laboratory staffs notes enter a file management system so they can be accessed to aid in clinical support. Knowledge sharing using this function can achieve the transition from individual to organizational learning. Storing guidelines for laboratory medicine will support EBM. Finally, it is expected that this system will support intellectual activity concerning laboratory work and contribute to the practice of knowledge management for clinical work support.

    Strengthening Laboratory Management Toward Accreditation (SLMTA) is a competency-based management training programme. Assessing health professionals' views of SLMTA provides feedback to inform program planning, implementation and evaluation of SLMTA's training, communication and mentorship components. To assess laboratory professionals' and hospital chief executive officers' (CEOs) perceptions and attitudes toward the SLMTA programme in Ethiopia. A cross-sectional descriptive survey was conducted in March 2013 using a structured questionnaire to collect qualitative data from 72 laboratory professionals and hospital CEOs from 17 health facilities, representing all regions and two city administrations in Ethiopia. Focus groups were conducted with laboratory professionals and hospital administration to gain insight into the strengths and challenges of the SLMTA programme so as to guide future planning and implementation. Ethiopian laboratory professionals at all levels had a supportive attitude toward the SLMTA programme. They believed that SLMTA substantially improved laboratory services and acted as a catalyst for total healthcare reform and improvement. They also noted that the SLMTA programme achieved marked progress in laboratory supply chain, sample referral, instrument maintenance and data management systems. In contrast, nearly half of the participating hospital CEOs, especially those associated with low-scoring laboratories, were sceptical about the SLMTA programme, believing that the benefits of SLMTA were outweighed by the level of human resources and time commitment required. They also voiced concerns about the cost and sustainability of SLMTA. This study highlights the need for stronger engagement and advocacy with hospital administration and the importance of addressing concerns about the cost and sustainability of the SLMTA programme.

    International Organization for Standardization (ISO) have published two international standards (IS) to be used for accreditation of clinical laboratories; ISO/IEC 17025:1999 and ISO 15189:2003. Any laboratory accreditation body must satisfy the requirements stated in ISO/IEC Guide 58. In order to maintain the quality of the laboratory accreditation bodies worldwide, the International Laboratory Accreditation Cooperation (ILAC) has established the mutual recognition arrangement (MRA). In Japan, the International Accreditation Japan (IAJapan) and the Japan Accreditation Board for Conformity Assessment (JAB) are the members of the ILAC/MRA group. In 2003, the Japanese Committee for Clinical Laboratory Standards (JCCLS) and the JAB have established the Development Committee of Clinical Laboratory Accreditation Program (CLAP), in order to establish the CLAP, probably starting in 2005.

    2017-02-01

    Healthcare is a significant contributor to environmental impact but this has received little attention. The typical laboratory uses far more energy and water per unit area than the typical office building. There is a need to sensitise laboratories to the importance of adopting good environmental practices. Since this comes at an initial cost, it is vital to obtain senior management support. Convincing management of the various tangible and intangible benefits that can accrue in the long run should help achieve this support. Many good environmental practices do not have a cost but will require a change in the culture and mind-set of the organisation. Continuing education and training are important keys to successful implementation of good practices. There is a need to undertake a rigorous cost-benefit analysis of every change that is introduced in going green. The adoption of good practices can eventually lead to ISO certification if this is desired. This paper provides suggestions that will allow a laboratory to start going green. It will allow the industry to enhance its corporate citizenship whilst improving its competitive advantage for long-term.

    Research coordinators have significant responsibilities in clinical trials that often require them to find unique ways to manage their jobs, thus reshaping their professional identities. The purpose of this study was to identify how research coordinators manage role and ethical conflicts within clinical research trials. A qualitative study combining observation and 63 semistructured interviews at 25 research organizations was used. Altruism is a recurring theme in how research coordinators define and view their work. Altruism is adopted by research coordinators to: (1) Teach patient-subjects the appropriate reasons to participate in clinical research, (2) minimize the conflict between research and care, and (3) contest the undervaluation of coordinating. Altruism is a strategy used to handle the various conflicts they experience in a difficult job, and it has become part of the professional identity of clinical research coordinators.

The 2014 Vacancy Survey was conducted through collaboration between American Society for Clinical Pathology's Institute of Science, Technology, and Policy in Washington, DC, and the Evaluation, Measurement, and Assessment Department and Board of Certification in Chicago, Illinois. Data were collected via an Internet survey that was distributed to individuals who were able to report on staffing and certifications for their laboratories. Data reveal increased overall vacancy rates since 2012 for all departments surveyed except cytology and cytogenetics. Also, results show higher anticipated retirement rates for both staff and supervisors. Overall certification rates are highest among laboratory personnel in cytogenetics, hematology/coagulation, and flow cytometry departments and lowest among phlebotomy, specimen processing, and anatomic pathology. Factors such as retirement and the improving economy are driving the need for more laboratory professionals. Recruitment of qualified laboratory professionals in the workforce and students in laboratory programs will be the key in fulfilling the higher vacancies revealed from the survey results in 2014.

    Full Text Available Purpose: "Introduction to Clinical Medicine" in Isfahan University of Medical Sciences and Health Services is an initiative in which general practitioners work as instructors and have the opportunity to experience teaching in addition to clinical practice. Since teaching, affects both teacher and students, this study aims to assess the influence of teaching clinical skills on the instructors' psychological, social and professional behaviour. Methods: This was performed as a qualitative study. The research population consisted of instructors of “Introduction to Clinical Medicine” who were all general practitioners and acted as facilitator in small groups working on physical examination and case discussion. The data collecting tool was a semi-structured interview which was recorded on the tape. Then, the interviews were transcribed and confirmed by interviewees at the end. 10 instructors were interviewed. The data were analysed according to Colaizzi model. Results: After coding the data to 38 main subjects, they were classified into three main categories including professional, psychological and social effects. The influence of teaching on professional performance included performing a thorough and correct physical examination, taking a detailed and correct history, increasing decision making ability and increasing professional knowledge. Some of the psychological effects were increasing selfconfidence, job satisfaction and morale. The social effects of teaching were increasing social contacts, having a relationship with an academic environment and having a respectful job. Conclusion: Considering the positive effects of teaching on instructors, teaching clinical skills by general practitioners can increase general practitioners knowledge and clinical skills and improve their morale. It is recommended to train general practitioners both for teaching skills and clinical skills and consider this, as an opportunity for physicians’ continuing

    One important trend in the laboratory profession and quality management is the global convergence of laboratory operations. The goal of an accredited medical laboratory is to continue "offering useful laboratory service for diagnosis and treatment of the patients and also aid to the health of the nation". An accredited clinical laboratory is managed by a quality control system, it is competent technically and the laboratory service meets the needs of all its patients and physicians by taking the responsibility of all the medical tests and therapies. For this purpose, ISO 15189 international standard has been prepared by 2003. ISO 15189 standard is originated from the arrangement of ISO 17025 and ISO 9001:2000 standards. Many countries such as England, Germany, France, Canada and Australia have preferred ISO 15189 as their own laboratory accreditation programme, meeting all the requirements of their medical laboratories. The accreditation performance of a clinical microbiology laboratory is mainly based on five essential points; preanalytical, analytical, postanalytical, quality control programmes (internal, external, interlaboratory) and audits (internal, external). In this review article, general concepts on ISO 15189 accreditation standards for the clinical microbiology laboratories have been summarized and the status of a private laboratory (Acibadem LabMed, Istanbul) in Turkey has been discussed.

  12. The need for European professional standards and the challenges facing clinical microbiology.

    2010-06-01

    Microorganisms spread across national boundaries and the professional activities of clinical (medical) microbiologists are critical in minimising their impact. Clinical microbiologists participate in many activities, e.g. diagnosis, antibiotic therapy, and there is a need for a set of professional standards for Europe with a common curriculum, to build upon the current strengths of the specialty and to facilitate the free movement of specialists within the European Union. Such standards will also better highlight the important contribution of clinical microbiologists to healthcare. There is a move to larger centralised microbiology laboratories often located off-site from an acute hospital, driven by the concentration of resources, amalgamation of services, outsourcing of diagnostics, automation, an explosion in the range of staff competencies and accreditation. Large off-site centralised microbiology laboratories are often distant to the patient and may not facilitate the early detection of microbial spread. Ultimately, the needs of patients and the public are paramount in deciding on the future direction of clinical microbiology. Potential conflicts between integration on an acute hospital site and centralisation can be resolved by a common set of professional standards and a team-based approach that puts patients first.

    There is no specific toxicological screening of clinical laboratory parameters in clinical toxicology when it comes to acute exogenous poisoning. To determine routine clinical laboratory parameters and indicators for assessment of vital functions in patients with acute intoxications. One hundred and fifty-three patients were included in the present study. They were hospitalized in the Department of Clinical Toxicology at St. George University Hospital, Plovdiv for cerebral toxicity inducing medication (n = 45), alcohol (n = 40), heroin abuse (n = 33). The controls were 35. The laboratory tests were conducted in compliance with the standards of the clinical laboratory. We used the following statistical analyses: analysis of variance (the ucriterion of normal distribution, the Student's t-test, dispersion analysis based on ANOVA) and non-parametric analysis. Based on the routine hematological parameters with statistically significant changes in three groups of poisoning are: red blood cells, hematocrit, hemoglobin (except alcohol intoxication) and leukocytes. We found statistically significant changes in serum total protein, sodium and bilirubin. The highest statistical significance is the increased activity of AST and ALT. We present a model for selection of clinical laboratory tests for severe acute poisoning with modern equipment under standardized conditions. The results of the study suggest that the clinical laboratory constellation we used can be used as a mandatory element in the diagnosis of moderate and severe intoxication with the mentioned toxic substances.

    The CAP (College of American Pathologists) was established in 1962 and, at present, CAP-accredited laboratories include about 6000 institutions all over the world, mainly in the U.S. The essential purpose of CAP accreditation is high quality reservation and improvement of clinical laboratory services for patient care, and is based on seven points, listed below. (1) Establishment of a laboratory management program and laboratory techniques to assure accuracy and improve overall quality of laboratory services. (2) Maintenance and improvement of accuracy objectively by centering on a CAP survey. (3) Thoroughness in safety and health administration. (4) Reservation of the performance of laboratory services by personnel and proficiency management. (5) Provision of appropriate information to physicians, and contribution to improved quality of patient care by close communication with physicians (improvement in patient care). (6) Reduction of running costs and personnel costs based on evidence by employing the above-mentioned criteria. (7) Reduction of laboratory error. In the future, accreditation and/or certification by organizations such as CAP, ISO, etc., may become a requirement for providing any clinical laboratory services in Japan. Taking the essence of the CAP and the characteristics of the new international standard, ISO151589, into consideration, it is important to choose the best suited accreditation and/or certification depending of the purpose of clinical laboratory.

    To evaluate clinic based and laboratory tests of otolith function for their sensitivity and specificity in demarcating unilateral compensated complete vestibular deficit from normal. Prospective cross-sectional study. Tertiary care hospital vestibular physiology laboratory. Control group-30 healthy adults, 20-45 years age; Case group-15 subjects post vestibular shwannoma excision or post-labyrinthectomy with compensated unilateral complete audio-vestibular loss. Otolith function evaluation by precise clinical testing (head tilt test-HTT; subjective visual vertical-SVV) and laboratory testing (headroll-eye counterroll-HR-ECR; vesibular evoked myogenic potentials-cVEMP). Sensitivity and specificity of clinical and laboratory tests in differentiating case and control subjects. Measurable test results were universally obtained with clinical otolith tests (SVV; HTT) but not with laboratory tests. The HR-ECR test did not indicate any definitive wave forms in 10% controls and 26% cases. cVEMP responses were absent in 10% controls.HTT test with normative cutoff at 2 degrees deviations from vertical noted as 93.33% sensitive and 100% specific. SVV test with normative cutoff at 1.3 degrees noted as 100% sensitive and 100% specific. Laboratory tests demonstrated poorer specificities owing primarily to significant unresponsiveness in normal controls. Clinical otolith function tests, if conducted with precision, demonstrate greater ability than laboratory testing in discriminating normal controls from cases with unilateral complete compensated vestibular dysfunction.

    Patient safety is an international public health priority. Ophthalmology scientific societies and organisations have intensified their efforts in this field. As a tool to learn from errors, these efforts have been linked to the management of medical professional liability insurance through the analysis of claims. A review is performed on the improvements in patient safety, as well as professional liability issues in Ophthalmology. There is a high frequency of claims and risk of economic reparation of damage in the event of a claim in Ophthalmology. Special complaints, such as wrong surgery or lack of information, have a high risk of financial compensation and need strong efforts to prevent these potentially avoidable events. Studies focused on pathologies or specific procedures provide information of special interest to sub-specialists. The specialist in Ophthalmology, like any other doctor, is subject to the current legal provisions and appropriate mandatory training in the medical-legal aspects of health care is essential. Professionals must be aware of the fundamental aspects of medical professional liability, as well as specific aspects, such as defensive medicine and clinical safety. The understanding of these medical-legal aspects in the routine clinical practice can help to pave the way towards a satisfactory and safe professional career, and help in increasing patient safety. The aim of this review is to contribute to this training, for the benefit of professionals and patients. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

    Imported parasitosis represents an increasingly frequent diagnostic challenge for microbiology laboratories. A surge in immigration and international travel has led to a rise in the number of imported cases of parasitosis, and this trend is expected to continue in the future. The present article addresses this challenge by reviewing recommended diagnostic approaches and tests. Currently, microscopy is always recommended when analysing blood samples for parasites. If malaria is suspected, rapid antigen testing (including at least HRP2 antigen) should also be performed. The work-up for suspected leishmaniasis should include serology, culture, and in selected cases detection of antigen in urine. In suspected Chagas disease, two different serological tests should be performed. PCR for blood protozoa is highly sensitive, although it cannot be used to rule out Chagas disease, since this condition may be present without parasitemia. Accurate diagnosis of intestinal amebiasis usually requires PCR or antigen detection tests. In helminthiasis, traditional microscopy may need to be complemented with other tests, such as agar plate culture for strongyloidiasis, Og4C3 antigen detection for bancroftian filariasis, and antibody detection test for filariasis and schistosomiasis.

    The increased use of social media, cloud computing, and mobile devices has led to the emergence of guidelines and novel teaching efforts to guide students toward the appropriate use of technology. Despite this, violations of professional conduct are common. We sought to explore professional behaviors specific to appropriate use of technology by looking at changes in third-year medical students' attitudes and behaviors at the beginning and conclusion of their clinical clerkships. After formal teaching about digital professionalism, we administered a survey to medical students that described 35 technology-related behaviors and queried students about professionalism of the behavior (on a 5-point Likert scale), observation of others engaging in the behavior (yes or no), as well as personal participation in the behavior (yes or no). Students were resurveyed at the end of the academic year. Over the year, perceptions of what is considered acceptable behavior regarding privacy, data security, communications, and social media boundaries changed, despite formal teaching sessions to reinforce professional behavior. Furthermore, medical students who observed unprofessional behaviors were more likely to participate in such behaviors. Although technology is a useful tool to enhance teaching and learning, our results reflect an erosion of professionalism related to information security that occurred despite medical school and hospital-based teaching sessions to promote digital professionalism. True alteration of trainee behavior will require a cultural shift that includes continual education, better role models, and frequent reminders for faculty, house staff, students, and staff. ©Arash Mostaghimi, Aleksandra E Olszewski, Sigall K Bell, David H Roberts, Bradley H Crotty.

    Laboratory capacity in the developing world frequently lacks quality management systems (QMS) such as good clinical laboratory practices, proper safety precautions, and adequate facilities; impacting the ability to conduct biomedical research where it is needed most. As the regulatory climate changes globally, higher quality laboratory support is needed to protect study volunteers and to accurately assess biological parameters. The University of Bamako and its partners have undertaken a comprehensive QMS plan to improve quality and productivity using the Clinical and Laboratory Standards Institute standards and guidelines. The clinical laboratory passed the College of American Pathologists inspection in April 2010, and received full accreditation in June 2010. Our efforts to implement high-quality standards have been valuable for evaluating safety and immunogenicity of malaria vaccine candidates in Mali. Other disease-specific research groups in resource-limited settings may benefit by incorporating similar training initiatives, QMS methods, and continual improvement practices to ensure best practices.

    2005-01-01

    A definition has been agreed for the most senior professional (consultant) in clinical chemistry and laboratory medicine. A model job description for a consultant has been determined, which is intended to act as a toolkit to assist employing authorities and professional bodies to define the role of individual consultant posts. A total of 86 competences for a consultant have been designated and expressed in the form of simple generic proficiency standards. These competences have been allocated to six broad areas: clinical [13]; scientific [15]; technical [12]; communication [12]; management and leadership [20]; professional autonomy and accountability [14]. The competences are intended to be illustrative rather than definitive and to enable the duties of any consultant post to be defined. Assessment of competence is likely to entail consideration of qualifications, registration status, continuing professional development and performance review. The project is intended as a guide to European societies of clinical chemistry and laboratory medicine. The guide should be capable of local interpretation to encourage a greater degree of commonality in the role of the consultant whilst protecting national identity. The guide should stimulate international understanding and collaboration and contribute to an overall improvement in the quality of practice.

    2016-01-01

    The gathering of power unto themselves by physicians, a process supported by evidence-based practice, clinical guidelines, licensure, organizational culture, and other social factors, makes the ethics of power—the legitimation of physicians’ power—a core concept of clinical ethics. In the absence of legitimation, the physician’s power over patients becomes problematic, even predatory. As has occurred in previous issues of the Journal, the papers in the 2016 clinical ethics issue bear on the professionally responsible deployment of power by physicians. This introduction explores themes of physicians’ power in papers from an international group of authors who address autonomy and trust, the virtues of perinatal hospice, conjoined twins in ethics and law, addiction and autonomy in clinical research on addicting substances, euthanasia of patients with dementia in Belgium, and a pragmatic approach to clinical futility.

    Full Text Available Antiphospholipid antibodies (aPL represent a heterogeneous group of antibodies that recognize various antigenic targets including beta2 glycoprotein I (β2GPI, prothrombin (PT, activated protein C, tissue plasminogen activator, plasmin and annexin A2. The most commonly used tests to detect aPL are: lupus anticoagulant (LAC, a functional coagulation assay, anticardiolipin antibody (aCL and anti-β2GPI antibody (anti-β2GPI, which are enzyme-linked immunoassay (ELISA. Clinically aPL are associated with thrombosis and/or with pregnancy morbidity. Apparently aPL alone are unable to induce thrombotic manifestations, but they increase the risk of vascular events that can occur in the presence of another thrombophilic condition; on the other hand obstetrical manifestations were shown to be associated not only to thrombosis but mainly to a direct antibody effect on the trophoblast.

    Full Text Available Background: Strengthening Laboratory Management Toward Accreditation (SLMTA is a competency-based management training programme. Assessing health professionals’ views of SLMTA provides feedback to inform program planning, implementation and evaluation of SLMTA's training, communication and mentorship components. Objectives: To assess laboratory professionals’ and hospital chief executive officers’ (CEOs perceptions and attitudes toward the SLMTA programme in Ethiopia. Methods: A cross-sectional descriptive survey was conducted in March 2013 using a structured questionnaire to collect qualitative data from 72 laboratory professionals and hospital CEOs from 17 health facilities, representing all regions and two city administrations in Ethiopia. Focus groups were conducted with laboratory professionals and hospital administration to gain insight into the strengths and challenges of the SLMTA programme so as to guide future planning and implementation. Results: Ethiopian laboratory professionals at all levels had a supportive attitude toward the SLMTA programme. They believed that SLMTA substantially improved laboratory services and acted as a catalyst for total healthcare reform and improvement. They also noted that the SLMTA programme achieved marked progress in laboratory supply chain, sample referral, instrument maintenance and data management systems. In contrast, nearly half of the participating hospital CEOs, especially those associated with low-scoring laboratories, were sceptical about the SLMTA programme, believing that the benefits of SLMTA were outweighed by the level of human resources and time commitment required. They also voiced concerns about the cost and sustainability of SLMTA. Conclusion: This study highlights the need for stronger engagement and advocacy with hospital administration and the importance of addressing concerns about the cost and sustainability of the SLMTA programme.

    To assess the predictive ability of various aspects of the work environment for organizational commitment. A questionnaire measuring three dimensions of organizational commitment along with five aspects of work environment and 10 demographic and work setting characteristics was sent to a national, convenience sample of clinical laboratory professionals. All persons obtaining the CLS certification by NCA from January 1, 1997 to December 31, 2006. Only respondents who worked full-time in a clinical laboratory setting were included in the database. Levels of affective, normative, and continuance organizational commitment, organizational support, role clarity, role conflict, transformational leadership behavior of supervisor, and organizational type, total years work experience in clinical laboratories, and educational level of respondents. Questionnaire items used either a 7-point or 5-point Likert response scale. Based on multiple regression analysis for the 427 respondents, organizational support and transformational leadership behavior were found to be significant positive predictors of affective and normative organizational commitment. Work setting (non-hospital laboratory) and total years of work experience in clinical laboratories were found to be significant positive predictors of continuance organizational commitment. Overall the organizational commitment levels for all three dimensions were at the neutral rating or below in the slightly disagree range. The results indicate a less than optimal level of organizational commitment to employers, which were predominantly hospitals, by CLS practitioners. This may result in continuing retention problems for hospital laboratories. The results offer strategies for improving organizational commitment via the significant predictors.

    Infectious diseases are still a cause of high mortality and morbidity rates. Current microbiological diagnostic methods are based on culture and phenotypic identification of isolated microorganisms, which can be obtained in about 24-48 h. Given that the microbiological identification is of major importance for patient management, new diagnostic methods are needed in order to detect and identify microorganisms in a timely and accurate manner. Over the last few years, several molecular techniques based on the amplification of microbial nucleic acids have been developed with the aim of reducing the time needed for the identification of the microorganisms involved in different infectious processes. On the other hand, mass spectrometry has emerged as a rapid and consistent alternative to conventional methods for microorganism identification. This review describes the most widely used mass spectrometry technologies -matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) and electrospray ionization time-of-flight (ESI-TOF)-, both for protein and nucleic acid analysis, as well as the commercial platforms available. Related publications of most interest in clinical microbiology are also reviewed. Copyright © 2011 Elsevier España, S.L. All rights reserved.

    The Applied Pharmaceutical Software Meeting is held annually. It is sponsored by The Boston Society, a not-for-profit organization that coordinates a series of meetings within the global pharmaceutical industry. The meeting generally focuses on laboratory applications, but in recent years has expanded to include some software applications for clinical trials. The 2011 meeting emphasized the global laboratory environment. Global clinical trials generate massive amounts of data in many locations that must be centralized and processed for efficient analysis. Thus, the meeting had a strong focus on establishing networks and systems for dealing with the computer infrastructure to support such environments. In addition to the globally installed laboratory information management system, electronic laboratory notebook and other traditional laboratory applications, cloud computing is quickly becoming the answer to provide efficient, inexpensive options for managing the large volumes of data and computing power, and thus it served as a central theme for the meeting.

    To perform SWOT (strengths, weaknesses, opportunities, and threats) analysis of a clinical laboratory as an economic model that may be used to improve business performance of laboratories by removing weaknesses, minimizing threats, and using external opportunities and internal strengths. Impact of possible threats to and weaknesses of the Clinical Laboratory at Našice General County Hospital business performance and use of strengths and opportunities to improve operating profit were simulated using models created on the basis of SWOT analysis results. The operating profit as a measure of profitability of the clinical laboratory was defined as total revenue minus total expenses and presented using a profit and loss account. Changes in the input parameters in the profit and loss account for 2008 were determined using opportunities and potential threats, and economic sensitivity analysis was made by using changes in the key parameters. The profit and loss account and economic sensitivity analysis were tools for quantifying the impact of changes in the revenues and expenses on the business operations of clinical laboratory. Results of simulation models showed that operational profit of €470 723 in 2008 could be reduced to only €21 542 if all possible threats became a reality and current weaknesses remained the same. Also, operational gain could be increased to €535 804 if laboratory strengths and opportunities were utilized. If both the opportunities and threats became a reality, the operational profit would decrease by €384 465. The operational profit of the clinical laboratory could be significantly reduced if all threats became a reality and the current weaknesses remained the same. The operational profit could be increased by utilizing strengths and opportunities as much as possible. This type of modeling may be used to monitor business operations of any clinical laboratory and improve its financial situation by implementing changes in the next fiscal

The operational profit could be increased by utilizing strengths and opportunities as much as possible. This type of modeling may be used to monitor business operations of any clinical laboratory and improve its financial situation by

    Full Text Available AIM: Dengue is a major health problem in many parts of India and Gulbarga (North Karnataka was previously not a known endemic area f or dengue. Infection with dengue virus can cause a spectrum of three clinical syndromes , classic dengue fever (DF , dengue hemorrhagic fever (DHF and dengue shock syndrome (DSS. The present study was undertaken to determine the disease profile of dengue virus infection in hospitalized patients. METHODS AND MATERIAL: One hundred patients admitted in Basaveshwar Teaching and General hospital with fever more than 38.5 degree Celsius and IgM dengue positive were selected. They were followed from the onset of fever to twelve days or till they are recovered according to WHO discharge criteria whichever is earlier. They underwent relevant investigations to identify specific organ dysfunction and categorize them into the spectrum of Dengue fever in accordance to W HO criteria . RESULTS: Out of 100 cases in this study 70 cases belongs to DF , 23 cases to DHF and 7 cases to DSS based on WHO criteria. All the cases had fever (100%. Other common symptoms noted were myalgia (61% , joint pain (54% , headache (66% , vomitin g (55% , pain abdomen (48% , rash (41% , hepatomegaly (20% , bleeding (21% and shock (8%. Hess test was positive in 24% patients. Low platelet count of less than 100 , 000/cu mm according to WHO criteria was present in 73% patients. Deranged liver functio n test and renal parameters were seen in 26 and 8 patients respectively . Mortality documented was 7 patients due to delayed presentation. The average duration of hospital stay was 4.65 days. CONCLUSION: Dengue fever was a more common manifestation than DHF or DSS.

    2016-12-01

    Melioidosis is a potentially fatal infection caused by the bacterium Burkholderia pseudomallei Clinical diagnosis of melioidosis can be challenging since there is no pathognomonic clinical syndrome, and the organism is often misidentified by methods used routinely in clinical laboratories. Although the disease is more prevalent in Thailand and northern Australia, sporadic cases may be encountered in areas where it is not endemic, including the United States. Since the organism is considered a tier 1 select agent according to the Centers for Disease Control and Prevention and the U.S. Department of Agriculture Animal and Plant Health Inspection Service, clinical laboratories must be proficient at rapidly recognizing isolates suspicious for B. pseudomallei, be able to safely perform necessary rule-out tests, and to refer suspect isolates to Laboratory Response Network reference laboratories. In this minireview, we report a case of melioidosis encountered at our institution and discuss the laboratory challenges encountered when dealing with clinical isolates suspicious for B. pseudomallei or clinical specimens from suspected melioidosis cases.

    2015-10-01

    The strategy of international cooperation in the clinical laboratory field was analyzed to improve the quality of intervention by reviewing documents from international organizations and the Japanese government. Based on the world development agenda, the target of action for health has shifted from communicable diseases to non-communicable diseases (NCD). This emphasizes the importance of comprehensive clinical laboratories instead of disease-specific examinations in developing countries. To achieve this goal, the World Health Organization (WHO) has disseminated to the African and Asian regions the Laboratory Quality Management System (LQMS), which is based on the same principles of the International Organization of Standardization (ISO) 15189. To execute this strategy, international experts must have competence in project management, analyze information regarding the target country, and develop a strategy for management of the LQMS with an understanding of the technical aspects of laboratory work. However, there is no appropriate pre- and post-educational system of international health for Japanese international workers. Universities and academic organizations should cooperate with the government to establish a system of education for international workers. Objectives of this education system must include: (1) training for the organization and understanding of global health issues, (2) education of the principles regarding comprehensive management of clinical laboratories, and (3) understanding the LQMS which was employed based on WHO's initiative. Achievement of these objectives will help improve the quality of international cooperation in the clinical laboratory field.

    2016-12-01

    Clinical microbiology and public health laboratories are beginning to utilize next-generation sequencing (NGS) for a range of applications. This technology has the potential to transform the field by providing approaches that will complement, or even replace, many conventional laboratory tests. While the benefits of NGS are significant, the complexities of these assays require an evolving set of standards to ensure testing quality. Regulatory and accreditation requirements, professional guidelines, and best practices that help ensure the quality of NGS-based tests are emerging. This review highlights currently available standards and guidelines for the implementation of NGS in the clinical and public health laboratory setting, and it includes considerations for NGS test validation, quality control procedures, proficiency testing, and reference materials.

    Murine tumours have been used extensively to investigate the effects of heat and radiation, but there are significant differences between controlled laboratory studies and relatively uncontrolled clinical experience. From 1983 to 1986 a simple clinical system was developed in order to investigate biological questions in the clinic. This involved identifying a suitable patient population, reliable heating and thermometry, and methods of evaluating response of human tumours and their vasculature. (author)

  1. Building bridges between clinical and forensic toxicology laboratories.

    Martin, Bernardino Barcelo; Gomila, Isabel; Noce, Valeria

    2018-05-09

    Clinical and forensic toxicology can be defined as the two disciplines involved the detection, identification and measurement of xenobiotics in biological and non-biological specimens to help in the diagnosis, treatment, prognosis, prevention of poisonings and to disclose causes and contributory causes of fatal intoxications, respectively. This article explores the close connections between clinical and forensic toxicology in overlapping areas of interest. An update has been carried out of the following seven areas of interest in analytical toxicology: doping control, sudden cardiac death (SCD), brain death, sudden infant death syndrome (SIDS) and Munchausen syndrome by proxy (MSBP), prenatal exposure to drugs and fetal alcohol syndrome (FAS), drug-facilitated crimes (DFC) and intoxications by new psychoactive substances (NPS). While issues such as SCD, SIDS or doping control are investigated mainly in forensic laboratories, other as prenatal exposure to drugs or FAS are mainly treated in clinical laboratories. On the other hand, areas such MSBP, DFC or the intoxications by NPS are of interest in both laboratories. Some of these topics are initially treated in hospital emergency departments, involving clinical laboratories and sometimes lately derived to forensic laboratories. Conversely, cases with initial medical-legal implications and fatalities are directly handled by forensic toxicology, but may trigger further studies in the clinical setting. Many areas of common interest between clinical and forensic laboratories are building bridges between them. The increasing relationships are improving the growth, the reliability and the robustness of both kind of laboratories.

    2014-06-01

    A common laboratory practice is to repeat critical values before reporting the test results to the clinical care provider. This may be an unnecessary step that delays the reporting of critical test results without adding value to the accuracy of the test result. To determine the proportions of repeated chemistry and hematology critical values that differ significantly from the original value as defined by the participating laboratory, to determine the threshold differences defined by the laboratory as clinically significant, and to determine the additional time required to analyze the repeat test. Participants prospectively reviewed critical test results for 4 laboratory tests: glucose, potassium, white blood cell count, and platelet count. Participants reported the following information: initial and repeated test result; time initial and repeat results were first known to laboratory staff; critical result notification time; if the repeat result was still a critical result; if the repeat result was significantly different from the initial result, as judged by the laboratory professional or policy; significant difference threshold, as defined by the laboratory; the make and model of the instrument used for primary and repeat testing. Routine, repeat analysis of critical values is a common practice. Most laboratories did not formally define a significant difference between repeat results. Repeated results were rarely considered significantly different. Median repeated times were at least 17 to 21 minutes for 10% of laboratories. Twenty percent of laboratories reported at least 1 incident in the last calendar year of delayed result reporting that clinicians indicated had adversely affected patient care. Routine repeat analysis of automated chemistry and hematology critical values is unlikely to be clinically useful and may adversely affect patient care.

    Full Text Available Clinical work with suicidal people is a demanding area. Little is known about health professionals’ practices when faced with suicidal patients. The aims of this study were to: (1 describe the practices most likely to be adopted by professionals facing a suicidal patient and (2 analyze the differences according to professional characteristics (group, specific training on suicide, and experience with suicidal patients. A self-report questionnaire that was developed for this study was filled out by 239 participants. Participants were psychologists, psychiatrists, and general practitioners who work in different contexts: hospitals, public health centres, schools or colleges, and community centres. Principal components analysis, analyses of variance, and t-tests were used. Four components were identified: (1 Comprehensive risk assessment; (2 protocols, psychotherapy and connectedness; (3 multidisciplinary clinical approach; and, (4 family, explaining a total of variance of 44%. Positive associations between suicide-related variables (training and experience and practices were found. In general, health professionals’ practices are evidence-based, however a relevant percentage of professionals can benefit from training and improve their practices.

    Although fair distribution of healthcare services for older patients is an important challenge, qualitative research exploring clinicians' considerations in clinical prioritisation within this field is scarce. To explore how clinicians understand their professional role in clinical prioritisations in healthcare services for old patients. A semi-structured interview-guide was employed to interview 45 clinicians working with older patients. The interviews were analysed qualitatively using hermeneutical content analysis. 20 physicians and 25 nurses working in public hospitals and nursing homes in different parts of Norway. The clinicians struggle with not being able to attend to the comprehensive needs of older patients, and being unfaithful to professional ideals and expectations. There is a tendency towards lowering the standards and narrowing the role of the clinician. This is done in order to secure the vital needs of the patient, but is at the expense of good practice and holistic role modelling. Increased specialisation, advances and increase in medical interventions, economical incentives, organisational structures, and biomedical paradigms, may all contribute to a narrowing of the clinicians' role. Distributing healthcare services in a fair way is generally not described as integral to the clinicians' role in clinical prioritisations. If considerations of justice are not included in clinicians' role, it is likely that others will shape major parts of their roles and responsibilities in clinical prioritisations. Fair distribution of healthcare services for older patients is possible only if clinicians accept responsibility in these questions.

    2014-12-01

    The number of commercial laboratories for clinical testing in Japan run privately has decreased to about 30 companies, and their business is getting tougher. Branch Lab. and FMS businesses have not expanded recently due to the new reimbursement system which adds an additional sample management fee, becoming effective in 2010. This presentation gives an outline of each role for hospital and commercial laboratories, and their pros & cons considering the current medical situation. Commercial laboratories have investigated how to utilize ICT systems for sharing test information between hospitals and our facilities. It would be very helpful to clarify issues for each hospital. We will develop and create new values for clinical laboratory testing services and forge mutually beneficial relationships with medical institutions. (Review).

  7. International standards for tuberculosis care: Relevance and implications for laboratory professionals

    2007-01-01

    Full Text Available On World Tuberculosis (TB Day 2006, the International Standards for Tuberculosis Care (ISTC was officially released and widely endorsed by several agencies and organizations. The ISTC release was the culmination of a year long global effort to develop and set internationally acceptable, evidence-based standards for tuberculosis care. The ISTC describes a widely endorsed level of care that all practitioners, public and private, should seek to achieve in managing individuals who have or are suspected of having, TB and is intended to facilitate the effective engagement of all healthcare providers in delivering high quality care for patients of all ages, including those with smear-positive, smear-negative and extra-pulmonary TB, TB caused by drug-resistant Mycobacterium tuberculosis and TB/HIV coinfection. In this article, we present the ISTC, with a special focus on the diagnostic standards and describe their implications and relevance for laboratory professionals in India and worldwide. Laboratory professionals play a critical role in ensuring that all the standards are actually met by providing high quality laboratory services for smear microscopy, culture and drug susceptibility testing and other services such as testing for HIV infection. In fact, if the ISTC is widely followed, it can be expected that there will be a greater need and demand for quality assured laboratory services and this will have obvious implications for all laboratories in terms of work load, requirement for resources and trained personnel and organization of quality assurance systems.

    More than 50 Norwegian public and private laboratories provide one or more analyses for therapeutic drug monitoring or testing for drugs of abuse. Practices differ among laboratories, and analytical repertoires can change rapidly as new substances become available for analysis. The Pharmacology Portal was developed to provide an overview of these activities and to standardize the practices and terminology among laboratories. The Pharmacology Portal is a modern dynamic web database comprising all available analyses within therapeutic drug monitoring and testing for drugs of abuse in Norway. Content can be retrieved by using the search engine or by scrolling through substance lists. The core content is a substance registry updated by a national editorial board of experts within the field of clinical pharmacology. This ensures quality and consistency regarding substance terminologies and classification. All laboratories publish their own repertoires in a user-friendly workflow, adding laboratory-specific details to the core information in the substance registry. The user management system ensures that laboratories are restricted from editing content in the database core or in repertoires within other laboratory subpages. The portal is for nonprofit use, and has been fully funded by the Norwegian Medical Association, the Norwegian Society of Clinical Pharmacology, and the 8 largest pharmacologic institutions in Norway. The database server runs an open-source content management system that ensures flexibility with respect to further development projects, including the potential expansion of the Pharmacology Portal to other countries.

    2000-01-01

    To determine essential content areas of immunology/serology courses at the clinical laboratory technician (CLT) and clinical laboratory scientist (CLS) levels. A questionnaire was designed which listed all major topics in immunology and serology. Participants were asked to place a check beside each topic covered. For an additional list of serological and immunological laboratory testing, participants were asked to indicate if each test was performed in either the didactic or clinical setting, or not performed at all. A national survey of 593 NAACLS approved CLT and CLS programs was conducted by mail under the auspices of ASCLS. Responses were obtained from 158 programs. Respondents from all across the United States included 60 CLT programs, 48 hospital-based CLS programs, 45 university-based CLS programs, and 5 university-based combined CLT and CLS programs. The survey was designed to enumerate major topics included in immunology and serology courses by a majority of participants at two distinct educational levels, CLT and CLS. Laboratory testing routinely performed in student laboratories as well as in the clinical setting was also determined for these two levels of practitioners. Certain key topics were common to most immunology and serology courses. There were some notable differences in the depth of courses at the CLT and CLS levels. Laboratory testing associated with these courses also differed at the two levels. Testing requiring more detailed interpretation, such as antinuclear antibody patterns (ANAs), was mainly performed by CLS students only. There are certain key topics as well as specific laboratory tests that should be included in immunology/serology courses at each of the two different educational levels to best prepare students for the workplace. Educators can use this information as a guide to plan a curriculum for such courses.

    To design, implement, and evaluate student performance on clinically relevant chemical and spectral laboratory exercises on antibiotics. In the first of 2 exercises, second-year pharmacy students enrolled in an integrated laboratory sequence course studied the aqueous stability of ß-lactam antibiotics using a spectral visual approach. In a second exercise, students studied the tendency of tetracycline, rifamycins, and fluoroquinolones to form insoluble chelate complexes (turbidity) with polyvalent metals. On a survey to assess achievement of class learning objectives, students agreed the laboratory activities helped them better retain important information concerning antibiotic stability and interactions. A significant improvement was observed in performance on examination questions related to the laboratory topics for 2012 and 2013 students compared to 2011 students who did not complete the laboratory. A 1-year follow-up examination question administered in a separate course showed >75% of the students were able to identify rifamycins-food interactions compared with laboratory exercises. The use of spectral visual approaches allowed students to investigate antibiotic stability and interactions, thus reinforcing the clinical relevance of medicinal chemistry. Students' performance on questions at the 1-year follow-up suggested increased retention of the concepts learned as a result of completing the exercises.

    2016-02-01

    The gathering of power unto themselves by physicians, a process supported by evidence-based practice, clinical guidelines, licensure, organizational culture, and other social factors, makes the ethics of power--the legitimation of physicians' power--a core concept of clinical ethics. In the absence of legitimation, the physician's power over patients becomes problematic, even predatory. As has occurred in previous issues of the Journal, the papers in the 2016 clinical ethics issue bear on the professionally responsible deployment of power by physicians. This introduction explores themes of physicians' power in papers from an international group of authors who address autonomy and trust, the virtues of perinatal hospice, conjoined twins in ethics and law, addiction and autonomy in clinical research on addicting substances, euthanasia of patients with dementia in Belgium, and a pragmatic approach to clinical futility. © The Author 2015.

    2015-12-01

    The process of developing effective science educators has been a long-standing objective of the broader education community. Numerous studies have recommended not only depth in a teacher's subject area but also a breadth of professional development grounded in constructivist principles, allowing for successful student-centered and inquiry-based instruction. Few programs, however, have addressed the integration of the scientific research laboratory into the science classroom as a viable approach to professional development. Additionally, while occasional laboratory training programs have emerged in recent years, many lack a component for translating acquired skills into reformed classroom instruction. Given the rapid development and demand for knowledgeable employees and an informed population from the biotech and medical industries in recent years, it would appear to be particularly advantageous for the physiology and broader science education communities to consider this issue. The goal of this study was to examine the effectiveness of a laboratory-based professional development program focused on the integration of reformed teaching principles into the classrooms of secondary teachers. This was measured through the program's ability to instill in its participants elevated academic success while gaining fulfillment in the classroom. The findings demonstrated a significant improvement in the use of student-centered instruction and other reformed methods by program participants as well as improved self-efficacy, confidence, and job satisfaction. Also revealed was a reluctance to refashion established classroom protocols. The combination of these outcomes allowed for construction of an experiential framework for professional development in applied science education that supports an atmosphere of reformed teaching in the classroom.

  1. The future of hospital laboratories. Position statement from the Royal Belgian Society of Clinical Chemistry (RBSCC).

    Science.gov (United States)

    Langlois, Michel R; Wallemacq, Pierre

    2009-01-01

    To face the economic pressures arising from the current socio-economic conjuncture, hospital laboratories are endangered by an increasing trend towards the outsourcing of clinical laboratory tests to external (mega-) laboratories. This should allow hospitals to meet their economic requirements, but with an increased risk of loss of medical quality and, mid- to long-term, loss of cost effectiveness of healthcare at the national level. To anticipate current developments (economical and technological) that inevitably will affect the future of laboratory medicine, hospital laboratories should be proactive and enhance efficiency, reduce costs by consolidation, integrate into regional networks, and form alliances or partnerships. To create additional value, the core competency of laboratory professionals must be refocused to provide medical knowledge services (consultative support to clinicians) related to in vitro diagnostic testing. To integrate cost-efficiency with medical quality, implementation of a matricial organization - operational vs. biomedical level - could be an interesting approach. This integrated structure should create total quality of laboratory testing, managing the entire medical diagnostic cycle from the pre-preanalytical to post-postanalytical phase.

    Drugs sometimes alter the results of clinical laboratory tests. We examined the effects of pralidoxime (PAM) salts, a medicine used to treat organophosphorus poisoning, on clinical laboratory test results for the first time. The effects of PAM salts on glucose (GLU) measurements were examined using a point-of-care testing (POCT) meter, four self-monitoring of blood glucose (SMBG) meters, and two biochemical autoanalyzers. The effects of PAM salts on other clinical tests were also evaluated. The addition of PAM iodide or potassium iodide, but not of PAM chloride or potassium chloride, to blood samples increased the GLU values measured by one POCT meter and 4 SMBG meters using the enzyme electrode (hydrogen peroxidase or oxygen electrode) method. On the other hand, PAM iodide or PAM chloride, but not KI or KCl, affected the values measured at 340 nm by an autoanalyzer using absorption spectrophotometry in 8 of 14 clinical laboratory tests. The absorption spectrum of PAM changed from 294 to 338 nm due to the reaction between PAM and the alkaline buffer, a component of the measuring reagents. PAM iodide increases the GLU values measured by the enzyme electrode method, and PAM salts affected the values measured at 340 nm by absorption spectrophotometry in many other clinical test items.

    Objectives: To propose a new conceptual model to gain insight and analyse factors that influence the laboratory–clinical staff interface. Methods: To develop the conceptual model, a literature study was performed, regulatory guidelines and standards for laboratories were analysed and discussions were held with experts on the topic. Result: A conceptual model and analytical framework provided good guidance in understanding and assessing the organisational and personal factors shaping the interface. The model was based on three elements: (1 the three phases of communication (pre-analytical, analytical and post-analytical; (2 the organisational and personal factors of interaction; and (3 the socio-political, economic and cultural context in which clinicians and laboratory staff operate. Conclusion: Assessment of the interface between clinicians and laboratory workers can be performed in a systematic way. Applying this model will provide information to managers of health institutions and heads of laboratories and clinical departments about what happens when clinicians and laboratory staff interact, thus aiding them in designing strategies to improve this interface.

    2008-05-01

    An increasing number of veterinary laboratories worldwide have obtained or are seeking certification based on international standards, such as the International Organization for Standardization/International Electrotechnical Commission 17025. Compliance with any certification standard or quality management system requires quality documentation, an activity that may present several unique challenges in the case of veterinary laboratories. Research specifically addressing quality documentation is conspicuously absent in the veterinary literature. This article provides an overview of the quality system documentation needed to comply with a quality management system with an emphasis on preparing written standard operating procedures specific for veterinary laboratories. In addition, the quality documentation challenges that are unique to veterinary clinical pathology laboratories are critically evaluated against the existing quality standards and discussed with respect to possible solutions and/or recommended courses of action. Documentation challenges include the establishment of quality requirements for veterinary tests, the use or modification of human analytic methods for animal samples, the limited availability of quality control materials satisfactory for veterinary clinical pathology laboratories, the limited availability of veterinary proficiency programs, and the complications in establishing species-specific reference intervals.

    In December 2009, the American Society for Veterinary Clinical Pathology (ASVCP) Quality Assurance and Laboratory Standards committee published the updated and peer-reviewed ASVCP Quality Assurance Guidelines on the Society's website. These guidelines are intended for use by veterinary diagnostic laboratories and veterinary research laboratories that are not covered by the US Food and Drug Administration Good Laboratory Practice standards (Code of Federal Regulations Title 21, Chapter 58). The guidelines have been divided into 3 reports: (1) general analytical factors for veterinary laboratory performance and comparisons; (2) hematology, hemostasis, and crossmatching; and (3) clinical chemistry, cytology, and urinalysis. This particular report is one of 3 reports and documents recommendations for control of preanalytical, analytical, and postanalytical factors related to urinalysis, cytology, and clinical chemistry in veterinary laboratories and is adapted from sections 1.1 and 2.2 (clinical chemistry), 1.3 and 2.5 (urinalysis), 1.4 and 2.6 (cytology), and 3 (postanalytical factors important in veterinary clinical pathology) of these guidelines. These guidelines are not intended to be all-inclusive; rather, they provide minimal guidelines for quality assurance and quality control for veterinary laboratory testing and a basis for laboratories to assess their current practices, determine areas for improvement, and guide continuing professional development and education efforts. © 2012 American Society for Veterinary Clinical Pathology.

  7. Bonding to oxide ceramics—laboratory testing versus clinical outcome.

    2015-01-01

    Despite a huge number of published laboratory bonding studies on dental oxide ceramics clinical long-term studies on resin bonded oxide ceramic restorations are rare. The purpose of this review is to present the best available clinical evidence for successful bonding of dental oxide ceramic restorations. Clinical trials with resin-bonded restorations that had no or only limited mechanical retention and were made from alumina or zirconia ceramic were identified using an electronic search in PubMed database. Overall 10 publications with clinical trials could be identified. Their clinical outcome was compared with that laboratory bond strength studies. Clinical data provide strong evidence that air-abrasion at a moderate pressure in combination with using phosphate monomer containing primers and/or luting resins provide long-term durable bonding to glass-infiltrated alumina and zirconia ceramic under the humid and stressful oral conditions. As simple and clinically reliable bonding methods to oxide ceramics exist, the rationale for development of alternative bonding methods might be reconsidered especially when these methods are more time consuming or require rather complicated and/or technique sensitive procedures.

    1997-01-01

    Competitive bidding to derive Medicare fees promises several advantages over administered fee systems. The authors show how incentives for cost savings, quality, and access can be incorporated into bidding schemes, and they report on a study of the clinical laboratory industry conducted in preparation for a bidding demonstration. The laboratory industry is marked by variable concentration across geographic markets and, among firms themselves, by social and economic heterogeneity. The authors conclude that these conditions can be accommodated by available bidding design options and by careful selection of bidding markets. PMID:10180003

  9. Clinical and laboratory profile of patients with sickle cell anemia

    Directory of Open Access Journals (Sweden)

    Phelipe Gabriel dos Santos Sant'Ana

    Full Text Available Abstract Objective: This study aimed to describe and analyze clinical and laboratory characteristics of patients with sickle cell anemia treated at the Hemominas Foundation, in Divinópolis, Brazil. Furthermore, this study aimed to compare the clinical and laboratory outcomes of the group of patients treated with hydroxyurea with those patients that were not treated with hydroxyurea. Methods: Clinical and laboratorial data were obtained by analyzing medical records of patients with sickle cell anemia. Results: Data from the medical records of 50 patients were analyzed. Most of the patients were female (56%, aged between 20 and 29 years old. Infections, transfusions, cholecystectomy, splenectomy and systemic arterial hypertension were the most common clinical adverse events of the patients. The most frequent cause of hospitalization was painful crisis. The majority of patients had reduced values of hemoglobin and hematocrit (8.55 ± 1.33 g/dL and 25.7 ± 4.4%, respectively and increased fetal hemoglobin levels (12 ± 7%. None of the clinical variables was statistically significant on comparing the two groups of patients. Among hematological variables only hemoglobin and hematocrit levels were statistically different between patients treated with hydroxyurea and untreated patients (p-value = 0.005 and p-value = 0.001, respectively. Conclusion: Sickle cell anemia requires treatment and follow-up by a multiprofessional team. A current therapeutic option is hydroxyurea. This drug reduces complications and improves laboratorial parameters of patients. In this study, the use of the drug increased the hemoglobin and hematocrit levels of patients.

  10. Secondary students in professional laboratories: Discoveries about science learning in a community of practitioners

    Song, Mary Elizabeth

    This study explores what educators may learn from the experiences of secondary students working in professional scientific laboratories. My investigation is guided by the methodology of phenomenological; I depend primarily on interviews conducted with students and professional researchers. This material is supported primarily by on-site observations, and by informal conversations between me and the study participants. My dissertation has three goals: (one) to use the work of secondary students in scientific research laboratories to consider how they know the discipline; (two) to distinguish the students' professional accomplishments from science learning at school; and, (three) to engage readers in a reflection about authority within the scientific community, and the possibility that by accomplishing research, students take their legitimate place among those who construct scientific knowledge. My methods and focus have allowed me to capture qualities of the student narratives that support the emergence of three major themes: the importance of doing "real work" in learning situations; the inapplicability of "school learning" to professional research arenas; and the inclusive nature of the scientific community. At the same time, the study is confined by the narrow pool of participants I interviewed over a short period of time. These talented students were all academically successful, articulate, "well-rounded" and in this sense, mature. They typically had strong family support, and they talked about ideas with their parents. Indeed, the students were all capable story-tellers who were anxious to share their experiences publicly. Yet they themselves remind the reader of their struggles to overcome naivete in the lab. By doing so they suggested to me that their experiences might be accessible to a broad range of young men and women; thus this study is a good beginning for further research.

    The goal of this paper is to verify the correlations between adaptive and maladaptive perfectionism and the selected demographic and job characteristics vs. professional burnout among medical laboratory scientists in Poland. The study group consisted of 166 laboratory scientists. The Polish Adaptive and Maladaptive Perfectionism Questionnaire (Szczucka) was used for testing perfectionism. The Oldenburg Burnout Inventory was used for examining burnout syndrome. Adaptive perfectionism was positively and maladaptive perfectionism was negatively correlated with both aspects of professional burnout: the disengagement from work and exhaustion. What is more, maladaptive perfectionism was correlated negatively with age and work experience. People in relationships have a higher level of disengagement and a higher level of exhaustion than single ones. The results of hierarchical regression analyses have revealed, after having controlled selected demographic and job factors, that a significant predictor of disengagement is the high level of adaptive perfectionism and low level of maladaptive perfectionism. In addition, a significant predictor of high level of exhaustion is the low level of maladaptive perfectionism. Professional burnout among medical laboratory scientists is of a specific nature. The "healthier" perfectionism they reveal, the higher level of burnout they present. In this profession, lower risk of burnout is represented by those who are characterized by the lack of confidence in the quality of their actions and a negative reaction to their own imperfections associated with imposed social obligation to be perfect. The individuals pursuing their internal high standards experience burnout faster. Med Pr 2018;69(3):253-260. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

    Duplicate laboratory tests that are unwarranted increase unnecessary phlebotomy, which contributes to iatrogenic anemia, decreased patient satisfaction, and increased health care costs. We employed a clinical decision support tool (CDST) to block unnecessary duplicate test orders during the computerized physician order entry (CPOE) process. We assessed laboratory cost savings after 2 years and searched for untoward patient events associated with this intervention. This CDST blocked 11,790 unnecessary duplicate test orders in these 2 years, which resulted in a cost savings of $183,586. There were no untoward effects reported associated with this intervention. The movement to CPOE affords real-time interaction between the laboratory and the physician through CDSTs that signal duplicate orders. These interactions save health care dollars and should also increase patient satisfaction and well-being.

  14. Evaluating the effectiveness of a laboratory-based professional development program for science educators

    Science.gov (United States)

    Amolins, Michael Wayne

    The development of effective science educators has been a long-standing goal of the American education system. Numerous studies have suggested a breadth of professional development programs that have sought to utilize constructivist principles in order to orchestrate movement toward student-led, inquiry-based instruction. Very few, however, have addressed a missing link between the modern scientific laboratory and the traditional science classroom. While several laboratory-based training programs have begun to emerge in recent years, the skills necessary to translate this information into the classroom are rarely addressed. The result is that participants are often left without an outlet or the confidence to integrate these into their lessons. The purpose of this study was to examine the effectiveness of a laboratory-based professional development program focused on classroom integration and reformed science teaching principles. This was measured by the ability to invigorate its seven participants in order to achieve higher levels of success and fulfillment in the classroom. These participants all taught at public high schools in South Dakota, including both rural and urban locations, and taught a variety of courses. Participants were selected for this study through their participation in the Sanford Research/USD Science Educator Research Fellowship Program. Through the use of previously collected data acquired by Sanford Research, this study attempted to detail the convergence of three assessments in order to demonstrate the growth and development of its participants. First, pre- and post-program surveys were completed in order to display the personal and professional growth of its participants. Second, pre- and post-program classroom observations employing the Reformed Teaching Observation Protocol allowed for the assessment of pedagogical modifications being integrated by each participant, as well as the success of such modifications in constructively

    Prior important research is not always cited, exemplified by Oswald Avery's pioneering discovery that DNA is the genetic transforming factor; it was not cited by Watson and Crick 10 years later. My first laboratory research (National Institutes of Health 1950s) resulted in the clinical development of transseptal left heart catheterization. Laboratory studies on cardiac muscle mechanics in normal and failing hearts led to the concept of afterload mismatch with limited preload reserve. At the University of California, San Diego in La Jolla (1968) laboratory experiments on coronary artery reperfusion after sustained coronary occlusion showed salvage of myocardial tissue, a potential treatment for acute myocardial infarction proven in clinical trials of thrombolysis 14 years later. Among 60 trainees who worked with me in La Jolla, one-third were Japanese and some of their important laboratory experiments are briefly recounted, beginning with Sasayama, Tomoike and Shirato in the 1970 s. Recently, we developed a method for cardiac gene transfer, and subsequently we showed that gene therapy for the defect in cardiomyopathic hamsters halted the progression of advanced disease. Cardiovascular research and medicine are producing continuing advances in technologies for gene transfer and embryonic stem cell transplantation, targeting of small molecules, and tissue and organ engineering.

    Read, Robert C; Cornaglia, Giuseppe; Kahlmeter, Gunnar

    2011-05-01

    The two closely linked specialties of clinical microbiology and infectious diseases face important challenges. We report the consensus of clinical microbiologists and infectious disease physicians assembled by the European Society for Clinical Microbiology and Infectious Diseases. Both specialties have different training requirements in different European countries and are not universally recognised as professions. The specialties are rapidly evolving as they adapt to the changing demands within hospital practice, including the need to deal with emerging infections, rapidly increasing internationalisation, and immigration. Clinical microbiology needs to develop and master technological advances such as laboratory automation and an avalanche of new methods for rapid diagnostics. Simultaneously, the pressure for concentration, amalgamation, and out-sourcing of laboratory services is ever-increasing. Infectious disease physicians have to meet the professional challenge of subspecialisation and the continual need to find new niches for their skills. Despite these challenges, each of these specialties continues to thrive in Europe and will enjoy important opportunities over the next few years. The recently formed European Centre for Disease Prevention and Control in Stockholm, Sweden, will increase demands in areas of surveillance of infectious diseases and antimicrobial resistance on both specialties.

    To discover the quality of written instructions from dentists to dental technicians and the nature of non-compliant prescriptions. An audit of laboratory prescription compliance was conducted within an NHS Trust Dental Teaching Hospital to determine the level of communication between dentists and dental technicians. One hundred and fifty prescriptions were audited from dental undergraduates and qualified dentists throughout the different departments. A total of two-thirds of prescriptions were considered non-compliant and failed to meet relevant ethical and legal guidelines. This problem was seen throughout all departments and at all professional levels. A breakdown in communication between dentists and technicians through the use of prescriptions is evident even within a close working environment.

    The purpose of this study was to investigate how science faculty members' belief systems about inquiry-based teaching changed through their experience in a professional development program. The program was designed to support early career science faculty in learning about inquiry and incorporating an inquiry-based approach to teaching laboratories. Data sources for this qualitative study included three semi-structured interviews, observations during the program and during faculty members' implementation in their courses, and a researcher's journal. In the first phase of data analysis, we created profiles for each of the four participants. Next, we developed assertions, and tested for confirming and disconfirming evidence across the profiles. The assertions indicated that, through the professional development program, participants' knowledge and beliefs about inquiry-based teaching shifted, placing more value on student-directed learning and classroom inquiry. Participants who were internally motivated to participate and held incoming positive attitudes toward the mini-journal inquiry-based approach were more likely to incorporate the approach in their future practice. Students' responses played a critical role in participants' belief systems and their decision to continue using the inquiry-based format. The findings from this study have implications for professional development design.

    To validate the performance, reproducibility, and reliability of BD automated instruments in order to establish a fully automated clinical microbiology laboratory. We used control strains and clinical samples to assess the accuracy, reproducibility, and reliability of the BD Kiestra WCA, the BD Phoenix, and BD Bruker MALDI-Biotyper instruments and compared them to previously established conventional methods. The following processes were evaluated: sample inoculation and spreading, colony counts, sorting of cultures, antibiotic susceptibility test, and microbial identification. The BD Kiestra recovered single colonies in less time than conventional methods (e.g. E. coli, 7h vs 10h, respectively) and agreement between both methodologies was excellent for colony counts (κ=0.824) and sorting cultures (κ=0.821). Antibiotic susceptibility tests performed with BD Phoenix and disk diffusion demonstrated 96.3% agreement with both methods. Finally, we compared microbial identification in BD Phoenix and Bruker MALDI-Biotyper and observed perfect agreement (κ=1) and identification at a species level for control strains. Together these instruments allow us to process clinical urine samples in 36h (effective time). The BD automated technologies have improved performance compared with conventional methods, and are suitable for its implementation in very busy microbiology laboratories. © American Society for Clinical Pathology 2017.

    Recent Solid State Photomultiplier (SSPM) technology has matured, reaching a performance level that is suitable for replacement of the ubiquitous photomultiplier tube in selected applications for environmental radiation monitoring, clinical dosimetry, and medical imaging purposes. The objective of this work is low signal level laboratory and high signal level clinical testing of the Hamamatsu MPPC (S10362-11-050C), Photonique SSPM (0810G1), and Voxtel SiPM (SQBF-EKAA/SQBF-EIOA) SSPMs coupled to different inorganic scintillator crystals (Prelude 420, BGO), inorganic doped glass scintillator material SiO 2 :Cu 2+ and organic BCF-12 plastic scintillating fibers, used as detector elements. Plastic Optical Fibers (POFs) and Glass Optical Fibers (GOFs) are used as signal conduits for laboratory and clinical testing. Further, reduction of electron-beam-generated Cerenkov light in optical fibers is facilitated by the inclusion of metalized air-core capillary tubing between the BCF-12 plastic scintillating fiber and the POF. In a clinical setting dose linearity, percent depth dose, and angular measurements for 6 MV/18 MV photon beams and 9 MeV electron beams are compared with and without the use of the air-core capillary tubing for BCF-12 plastic scintillating fiber. These same measurements are repeated for SiO 2 :Cu 2+ scintillator material without air-core capillary tubing.

    Full Text Available Recently, David Barlow (2004, a pioneer in the field of anxiety disorders, has proposed that psychologists should abandon the concept of psychotherapy and rather use the one of “psychological treatment”. The provoking idea behind this proposal is that the concept of psychotherapy, relying on the notion of “therapeutic school” should be discarded by professional psychologists because it relies too much on conceptions based on pre-scientific models. Barlow (2004 insists that, today, psychology as an empirical science has gathered sufficient knowledge and know-how to found clinical practice. It is no longer necessary to rely on pre-scientific theories. Further, Barlow’s perspective opens clinical practice to the entire field of psychology, i.e. to the advances accomplished by research on emotion, cognition, learning, development, etc.

    Effective implementation and sustainability of quality laboratory programmes in Sub-Saharan Africa relies on the development of appropriate staff retention strategies. Assessing the factors responsible for job satisfaction and retention is key for tailoring specific interventions aiming at improving the overall impact of health programmes. A survey was developed to assess these factors among 224 laboratorians working in the laboratory programme the University of Maryland implemented in seven Sub-Saharan African countries. Lack of professional development was the major reason for leaving the previous job for 28% of interviewees who changed jobs in the past five years. Professional development/training opportunities was indicated by almost 90% (195/224) of total interviewees as the most important or a very important factor for satisfaction at their current job. Similarly, regular professional development/opportunities for training was the highest rated incentive to remain at their current job by 80% (179/224). Laboratory professionals employed in the private sector were more likely to change jobs than those working in the public sector (P = 0.002). The findings were used for developing specific strategies for human resources management, in particular targeting professional development, aiming at improving laboratory professionals within the University of Maryland laboratory programme and hence its long-term sustainability.

    The International Standards for Cytogenomic Arrays (ISCA) Consortium is a worldwide collaborative effort dedicated to optimizing patient care by improving the quality of chromosomal microarray testing. The primary effort of the ISCA Consortium has been the development of a database of copy number variants (CNVs) identified during the course of clinical microarray testing. This database is a powerful resource for clinicians, laboratories, and researchers, and can be utilized for a variety of applications, such as facilitating standardized interpretations of certain CNVs across laboratories or providing phenotypic information for counseling purposes when published data is sparse. A recognized limitation to the clinical utility of this database, however, is the quality of clinical information available for each patient. Clinical genetic counselors are uniquely suited to facilitate the communication of this information to the laboratory by virtue of their existing clinical responsibilities, case management skills, and appreciation of the evolving nature of scientific knowledge. We intend to highlight the critical role that genetic counselors play in ensuring optimal patient care through contributing to the clinical utility of the ISCA Consortium's database, as well as the quality of individual patient microarray reports provided by contributing laboratories. Current tools, paper and electronic forms, created to maximize this collaboration are shared. In addition to making a professional commitment to providing complete clinical information, genetic counselors are invited to become ISCA members and to become involved in the discussions and initiatives within the Consortium.

    2014-09-01

    The incidence of Candida bloodstream infection (BSI) has been on the rise in several countries worldwide. Species distribution is changing; an increase in the percentage of non-albicans species, mainly fluconazole non-susceptible C. glabrata was reported. Existing microbiology diagnostic methods lack sensitivity, and new methods need to be developed or further evaluation for routine application is necessary. Although reliable, standardized methods for antifungal susceptibility testing are available, the determination of clinical breakpoints remains challenging. Correct species identification is important and provides information on the intrinsic susceptibility profile of the isolate. Currently, acquired resistance in clinical Candida isolates is rare, but reports indicate that it could be an issue in the future. The role of the clinical microbiology laboratory is to isolate and correctly identify the infective agent and provide relevant and reliable susceptibility data as soon as possible to guide antifungal therapy.

    Training clinical laboratory science (CLS) students in techniques of preparation and delivery of an instructional unit is an important component of all CLS education programs and required by the national accrediting agency. Participants of this study included students admitted to the CLS program at Northern Illinois University and enrolled in the teaching course offered once a year between the years of 1997 and 2009. Courses on the topic of "teaching" may be regarded by CLS students as unnecessary. However, entry level practitioners are being recruited to serve as clinical instructors soon after entering the workforce. Evaluation of the data collected indicates that students are better prepared to complete tasks related to instruction of a topic after having an opportunity to study and practice skills of teaching. Mentoring CLS students toward the career role of clinical instructor or professor is important to maintaining the workforce.

    Increasing numbers of clinical laboratories are transitioning away from flame and electrothermal AAS methods to those based on ICP-MS. Still, for many laboratories, the choice of instrumentation is based upon (a) the element(s) to be determined, (b) the matrix/matrices to be analyzed, and (c) the expected concentration(s) of the analytes in the matrix. Most clinical laboratories specialize in measuring Se, Zn, Cu, and Al in serum, and/or Pb, Cd, Hg, As, and Cr in blood and/or urine, while other trace elements (e.g., Pt, Au etc.) are measured for therapeutic purposes. Quantitative measurement of elemental species is becoming more widely accepted for nutritional and/or toxicological screening purposes, and ICP-MS interfaced with separation techniques, such as liquid chromatography or capillary electrophoresis, offers the advantage of on-line species determination coupled with very low detection limits. Polyatomic interferences for some key elements such as Se, As, and Cr require instrumentation equipped with dynamic reaction cell or collision cell technologies, or might even necessitate the use of sector field ICP-MS, to assure accurate results. Nonetheless, whatever analytical method is selected for the task, careful consideration must be given both to specimen collection procedures and to the control of pre-analytical variables. Finally, all methods benefit from access to reliable certified reference materials (CRMs). While a variety of reference materials (RMs) are available for trace element measurements in clinical matrices, not all can be classified as CRMs. The major metrological organizations (e.g., NIST, IRMM, NIES) provide a limited number of clinical CRMs, however, secondary reference materials are readily available from commercial organizations and organizers of external quality assessment schemes.

While a variety of reference materials (RMs) are available for trace element measurements in clinical matrices, not all can be classified as CRMs. The major metrological organizations (e.g., NIST, IRMM, NIES) provide a limited number of clinical CRMs, however, secondary reference materials are readily available from commercial organizations and organizers of external quality assessment schemes

    Full Text Available Introduction: Kikuchi-Fujimoto disease is an uncommon disorder with worldwide distribution, characterized by fever and benign enlargement of the lymph nodes, primarily affecting young adults. Awareness about this disorder may help prevent misdiagnosis and inappropriate investigations and treatment. The objective of the study was to evaluate the clinical and laboratory characteristics of histopathologically confirmed cases of Kikuchi′s disease from a tertiary care center in southern India. Materials and Methods: Retrospective analysis of all adult patients with histopathologically confirmed Kikuchi′s disease from January 2007 to December 2011 in a 2700-bed teaching hospital in South India was done. The clinical and laboratory characteristics and outcome were analyzed. Results: There were 22 histopathologically confirmed cases of Kikuchi′s disease over the 5-year period of this study. The mean age of the subjects′ was 29.7 years (SD 8.11 and majority were women (Male: female- 1:3.4. Apart from enlarged cervical lymph nodes, prolonged fever was the most common presenting complaint (77.3%. The major laboratory features included anemia (54.5%, increased erythrocyte sedimentation rate (31.8%, elevated alanine aminotransferase (27.2% and elevated lactate dehydrogenase (LDH (31.8%. Conclusion: Even though rare, Kikuchi′s disease should be considered in the differential diagnosis of young individuals, especially women, presenting with lymphadenopathy and prolonged fever. Establishing the diagnosis histopathologically is essential to avoid inappropriate investigations and therapy.

    Quality control is an essential component in every clinical laboratory which maintains the excellence of laboratory standards, supplementing to proper disease diagnosis, patient care and resulting in overall strengthening of health care system. Numerous quality control schemes are available, with combinations of procedures, most of which are tedious, time consuming and can be "too technical" whereas commercially available quality control materials can be expensive especially for laboratories in developing nations like Nepal. Here, we present a procedure performed at our centre with self prepared control serum and use of simple statistical tools for quality assurance. The pooled serum was prepared as per guidelines for preparation of stabilized liquid quality control serum from human sera. Internal Quality Assessment was performed on this sample, on a daily basis which included measurement of 12 routine biochemical parameters. The results were plotted on Levey-Jennings charts and analysed with quality control rules, for a period of one month. The mean levels of biochemical analytes in self prepared control serum were within normal physiological range. This serum was evaluated every day along with patients' samples. The results obtained were plotted on control charts and analysed using common quality control rules to identify possible systematic and random errors. Immediate mitigation measures were taken and the dispatch of erroneous reports was avoided. In this study we try to highlight on a simple internal quality control procedure which can be performed by laboratories, with minimum technology, expenditure, and expertise and improve reliability and validity of the test reports.

    We developed a Microsoft Access-based laboratory management system to facilitate database management of leukemia patients referred for cytogenetic tests in regards to karyotyping and fluorescence in situ hybridization (FISH). The database is custom-made for entry of patient data, clinical details, sample details, cytogenetics test results, and data mining for various ongoing research areas. A number of clinical research laboratoryrelated tasks are carried out faster using specific "queries." The tasks include tracking clinical progression of a particular patient for multiple visits, treatment response, morphological and cytogenetics response, survival time, automatic grouping of patient inclusion criteria in a research project, tracking various processing steps of samples, turn-around time, and revenue generated. Since 2005 we have collected of over 5,000 samples. The database is easily updated and is being adapted for various data maintenance and mining needs.

    For the occasion of the 50th anniversary of the journal Clinical Chemistry and Laboratory Medicine (CCLM), an historic overview of papers that the journal has published in the field of laboratory hematology (LH) is presented. All past volumes of CCLM were screened for papers on LH and these were categorized. Bibliographic data of these papers were also analyzed. CCLM published in total 387 LH papers. The absolute number of LH papers published annually showed a significant increase over the years since 1985. Also the share of LH papers demonstrated a steady increase (overall mean 5%, but mean 8% over the past 4 years). The most frequent category was coagulation and fibrinolysis (23.5%). Authors from Germany contributed the most LH papers to the journal (22.7%), followed by the Netherlands and Italy (16.3 and 13.2%, respectively). Recent citation data indicated that other publications cited LH review papers much more frequently than other types of papers. The history of the journal reflects the emergence and development of laboratory hematology as a separate discipline of laboratory medicine.

    Continuing education is one of the means by which professionals maintain and increase their level of competence. However, the relationship between continuing education and the professional's sense of personal competence and other practice-related variables remains unclear. This study examined practicing psychologists' continuing education activities and how these relate to feelings of perceived competence, professional value, and professional support. Psychologists (n = 418) licensed to practice in Quebec were surveyed by pencil-and-paper mail-in survey concerning their continuing education activities, as well as their perceptions of their competence in practice, and their feelings of being professionally valued and professionally supported. Results indicated that feelings of competence in practice were related to professional reading, taking courses/workshops, years being licensed, and attending psychology conferences/conventions. Feelings of professional value were related to age and participating in psychology networking groups, and feelings of professional support were related to participating in case discussion groups, supervision groups, and psychology networking groups. The results showcase the complexity of professional development. Although relationships were found between continuing education activities and the 3 factors of interest, these relationships were moderate. Findings are discussed in the context of their value to individual psychologists, as well as to psychology licensing and regulatory boards, such as promoting participation in those activities related to feelings of competence and support.

    2013-05-01

    The literature recognises a relationship between clinical experience and a successful undergraduate experience in nursing; however what constitutes an effective approach remains the subject of debate, particularly in relation to first year of learning. There is evidence from a biological standpoint that early experience impacts on the behavioural development of animals, described by Konrad Lorenz (1903-1989) as 'imprinting'. The concept of imprinting has resonance for nursing. In this article the importance of 'getting it right at the beginning' is explored and what, if anything, Lorenz's theory tells us about the impact of early clinical learning on subsequent professional development.

    The hospital infection control and prevention is recognized to be more and more important according to the advances in modern medical treatment and care. Clinical microbiology laboratory play critical roles in the hospital infection control as a member of infection control team (ICT). They are the first in a hospital to identify outbreak of MRSA in NICU and molecular epidemiological analysis of the isolates lead proper intervention of ICT to the concerned ward. From a viewpoint of infectious disease specialist, rapid and precise microbiological information is essential for the appropriate diagnosis and treatment of infectious diseases. Each medical technologist need to make efforts to understand the characteristics of the examinations for infectious diseases and send out information useful for clinical practices. In our hospital, with the participation of all members of medical technologists, rapid reporting system was developed for blood culture examinations, which greatly contribute to the appropriate treatment of bloodstream infections. Collaborations of clinical microbiology laboratory with other members of ICT realize high quality hospital infection control. They also need to be aware of themselves as good practitioners of infection control measures to prevent hospital infections.

    Blood samples are usually collected daily from different collection points, such hospitals and health centers, and transported to a core laboratory for testing. This paper presents a project to improve the collection routes of two of the largest clinical laboratories in Spain. These routes must be designed in a cost-efficient manner while satisfying two important constraints: (i) two-hour time windows between collection and delivery, and (ii) vehicle capacity. A heuristic method based on a genetic algorithm has been designed to solve the problem of blood sample collection. The user enters the following information for each collection point: postal address, average collecting time, and average demand (in thermal containers). After implementing the algorithm using C programming, this is run and, in few seconds, it obtains optimal (or near-optimal) collection routes that specify the collection sequence for each vehicle. Different scenarios using various types of vehicles have been considered. Unless new collection points are added or problem parameters are changed substantially, routes need to be designed only once. The two laboratories in this study previously planned routes manually for 43 and 74 collection points, respectively. These routes were covered by an external carrier company. With the implementation of this algorithm, the number of routes could be reduced from ten to seven in one laboratory and from twelve to nine in the other, which represents significant annual savings in transportation costs. The algorithm presented can be easily implemented in other laboratories that face this type of problem, and it is particularly interesting and useful as the number of collection points increases. The method designs blood collection routes with reduced costs that meet the time and capacity constraints of the problem.

    Epidemiological studies have contributed to the understanding of the total scope of the insomnia problem, both in terms of the incidence of sleep difficulties, and the extent and frequency of hypnotic drug use. Clinical studies - at the Sleep Research and Treatment Center - have been used to evaluate the medical, psychological, pharmacological and situational factors contributing to insomnia, and to evaluate the psychotherapy and chemotherapy best suited to treatment of insomnia. The sleep laboratory studies were of two types: (1) the study of sleep induction, sleep maintenance, and sleep stages, and (2) the use of hypnotic drugs, emphasizing their effectiveness in inducing and maintaining sleep, and the duration of this effectiveness.

    Leadership and management training during pathology residency have been identified repeatedly by employers as insufficient. A 1-month rotation in clinical laboratory management (CLM) was created for third-year pathology residents. We report on our experience and assess the value of this rotation. The rotation was one-half observational and one-half active. The observational component involved being a member of department and laboratory service line leadership, both at the departmental and institutional level. Observational participation enabled learning of both the content and principles of leadership and management activities. The active half of the rotation was performance of a project intended to advance the strategic trajectory of the department and laboratory service line. In our program that matriculates 4 residents per year, 20 residents participated from April 2010 through December 2015. Their projects either activated a new priority area or helped propel an existing strategic priority forward. Of the 16 resident graduates who had obtained their first employment or a fellowship position, 9 responded to an assessment survey. The majority of respondents (5/9) felt that the rotation significantly contributed to their ability to compete for a fellowship or their first employment position. The top reported benefits of the rotation included people management; communication with staff, departmental, and institutional leadership; and involvement in department and institutional meetings and task groups. Our 5-year experience demonstrates both the successful principles by which the CLM rotation can be established and the high value of this rotation to residency graduates. PMID:28725766

    This article aims to reflect on which areas or tasks of microbiology laboratories could be unified with those of clinical biochemistry, hematology, immunology or pathology laboratories to benefit patients and the health system, as well as the areas that should remain independent since their amalgamation would not only fail to provide a benefit but could even jeopardize the quality of microbiological diagnosis, and consequently patient care. To do this, the distinct analytic phases of diagnosis are analyzed, and the advantages and disadvantages of amalgamation are evaluated in each phase. The pros and cons of the unification of certain areas such as the computer system, occupational risk units, customer service, purchasing logistics, and materials storage, etc, are also discussed. Lastly, the effect of unification on urgent microbiology diagnosis is analyzed. Microbiological diagnosis should be unique. The microbiologist should perform an overall evaluation of the distinct techniques used for a particular patient, both those that involve direct diagnosis (staining, culture, antigen detection techniques or molecular techniques) and indirect diagnosis (antibody detection). Moreover, the microbiology laboratory should be independent, with highly trained technicians and specialists in microbiology that provide added value as experts in infection and as key figures in the process of establishing a correct etiological diagnosis.

    The use of Reference Change Values (RCV) has been advocated as very useful for monitoring individuals. Most of these are performed for monitoring individuals in acute situations and for following up the improvement or deterioration of chronic diseases. In our study, we aimed at evaluating the RCV calculation for 24 clinical chemistry analytes widely used in clinical laboratories and the utilization of this data. Twenty-four serum samples were analyzed with Abbott kits (Abbott Laboratories, Abbott Park, IL, USA), manufactured for use with the Architect c8000 (Abbott Laboratories, Abbott Park, IL, USA) auto-analyzer. We calculated RCV using the following formula: RCV = Z x 2 1/2x (CVA2 + CVw2)1/2. Four reference change values (RCV) were calculated for each analyte using four statistical probabilities (0.95, and 0.99, unidirectional and bidirectional). Moreover, by providing an interval after identifying upper and lower limits with the Reference Change Factor (RCF), serially measured tests were calculated by using two formulas: exp (Z x 2 1/2 x (CV(A)2 + CVw2)½/100) for RCF(UP) and (1/RCF(UP)) for RCF(DOWN). RCVs of these analytes were calculated as 14.63% for glucose, 29.88% for urea, 17.75% for ALP, 53.39% for CK, 46.98% for CK-MB, 21.00% amylase, 8.00% for total protein, 8.70% for albumin, 51.08% for total bilirubin, 86.34% for direct bilirubin, 6.40% for calcium, 15.03% for creatinine, 21.47% for urate, 14.19% for total cholesterol, 46.62% for triglyceride, 20.51% for HDL-cholesterol, 29.59% for AST, 46.31% for ALT, 31.54% for GGT, 20.92% for LDH, 19.75% for inorganic phosphate, 3.05% for sodium, 11.75% for potassium, 4.44% for chloride (RCV, p laboratories. RCV could be available as a tool for making clinical decision, especially when monitoring individuals.

Women’s age, gravity, parity, blood groups, pattern of menstrual cycles, complaints at presentation, fertility, ultrasonographical findings, surgical operations and thyroid function tests were evaluated.There were no significant differences in blood group distribution, gravity, parity and thyroid function test results between the patients and the control subjects (P>0.05. A significant difference was found in the complaints at presentation between two groups (P<0.001. Mentrual cycles irregularity was more frequently found in the patients compared with the controls (57.3% vs. 42.9%, respectively, P=0.009. Although no infertile woman was found in the control group, 8.5% of patients were found to have infertility. The sensitivity of ultrasonography was found to be 97.6%. Except for the existence of higher infertility rate and the menstrual cycles irregularities, no significant difference was found in the clinical and laboratory findings between women with or without uterine leiomyoma. Therefore, physical examination and imaging methods are remained as the most important diagnostic tools for uterine leiomyoma.

    1979-10-01

    The transmission of hepatitis B virus (HBV) in clinical laboratory areas was delineated by the use of hepatitis B surface antigen (HBsAg) as presumptive evidence for the presence of the infective agent. Twenty-six (34%) of 76 environmental surfaces sampled were positive for HBsAg. The outer surfaces of blood- and serum-specimen containers had HBsAg contamination rates of 55% (six of 11) and 44% (four of nine), respectively. Subsequent handling of pipetting aids, marking devices, and other items led to their contamination and further dissemination of HBsAg. An assay instrument for complete determinations of blood cell counts was observed to splatter and drip blood during its operation. The contamination rate for environmental surfaces associated with this instrument was 15%. The data indicate that transmission of HBV in the clinical laboratory is subtle and mainly via hand contact with contaminated items during the various steps of blood processing. These data support the concept that the portal of entry of HBV is through inapparent breaks in skin and mucous membranes.

    Full Text Available Background: Thrombocytopenia is an important cause of bleeding. Different clinical conditions associated with thrombocytopenia and their reflections to the hemostatic table will be examined in this study. Methods: A total of 100 patients with thrombocytopenia who were treated in Hacettepe University between 1993 and 2013, 29 with thrombotic thrombocytopenic purpura (TTP, 36 with immune thrombocytopenic purpura (ITP, and 35 with aplastic anemia (AA, were included in the study. Clinical features and laboratory values were reviewed. Results: Thrombosis, fever, and sepsis were more frequently seen in TTP. The most common bleeding type was subcutaneous bleeding in all patient groups. Among patients with TTP, twenty-five patients (86, 2% had fever, 26 patients (89, 7% had a neurologic disorder, and 16 patients (55, 1% had renal dysfunction. Regarding the diagnostic criteria of TTP, 13 patients (44, 8% met five, 12 (41, 4% patients met four and 4 (13, 8% patients met three criteria. The median session of plasmapheresis was 17 (range; 2-127. There was no relation between session count and remission (p=0.28. Conclusion: The severity of clinical presentation and underlying disorders are the most important points with which to approach patients with thrombocytopenia. Clinical reflections may help to identify the cause of thrombocytopenia but not sufficiently demonstrative for diagnosis. [J Contemp Med 2017; 7(4.000: 316-322

  10. An evaluation of clinical laboratory services in sub-Saharan Africa. Ex africa semper aliquid novi?

    Science.gov (United States)

    Gray, I P; Carter, J Y

    1997-11-06

    Pathology services represent the rational, scientific basis of the practice of clinical care. It does not represent deus ex machina, an implausible solution to a complex plot, but rather the way in which clinical care can be audited, controlled, guided and kept appropriate to the funds and the skills available. Arguments are presented to support this statement as well as to analyse what is wrong with health care, from the point of view of laboratory medicine, in sub-Saharan Africa. In most African countries 'first world' technology has to be imported by economies barely able to sustain the basic requirements of human life. Badly needed foreign exchange is obtained by growing export crops at the cost of traditional lifestyle, disenfranchising communities, urbanisation, and even at the cost not being able to grow food. War, corruption, lack of accountability even in the Western sense of being able to go to the polls every so often, lack of empowerment, low literacy rate etc all debase the communities, with minimal exceptions, of Africa. Health care is under the same capricious rule as all other public services: investment in laboratories is poor and most have no access to a professional laboratory at all. More investment, not less; expansion of pathology services not restricting them, is needed throughout the continent.

    2007-08-01

    This study evaluated the short- and long-term effectiveness of faculty training to enhance clinical evaluation of ethical reasoning and professionalism in a baccalaureate dental hygiene program. Ethics, values, and professionalism are best measured in contexts comparable to practice; therefore, authentic evaluation is desirable for assessing these areas of competence. Methods were the following: 1) a faculty development workshop implementing a core values-based clinical evaluation system for assessing students' professional judgment; 2) subsequent evaluation of the clinical faculty's use of core values for grading and providing written comments related to students' professional judgment during patient care for three academic years; and 3) evaluation of program outcomes assessments regarding clinical learning experiences related to ethics and professionalism domains. Results revealed the clinical faculty's evaluation of professional judgment during patient care was enhanced by training; written comments more frequently related to core values defined in the American Dental Hygienists' Association (ADHA) Code of Ethics; and faculty members reported more confidence and comfort evaluating professional judgment after implementation of this evaluation system and receiving training in its application. Students were more positive in outcomes assessments about their competency and learning experiences related to professionalism and ethics. This article shares one approach for enhancing clinical faculty's authentic evaluation of student competence in ethical reasoning and professionalism.

    2014-04-01

    Full Text Available Among numerous viral meningitises from 80% to 90% of cases are accounted for meningitis of enteroviral etiology according to the international data. Despite the favorable disease course, there are forms which are characterized by severe damage of CNS. In order to improve diagnostics of enteroviral meningitis in this article we have made a comparative analysis of clinical and laboratory parameters in 23 patients with enteroviral meningitis and 18 patients with serous meningitis of non-enteroviral etiology. Anamnesis data and the major clinical manifestations of the disease dynamics were analyzed. Particular attention is paid to the comparison of diagnoses, by which patients were sent to infectious hospital, the symptoms that occurred during patients’ admission into hospitals and their severity. The presence and severity of meningeal symptoms and the indices of cerebrospinal fluid in the patients of the comparison group were analyzed in detail. It is shown that enteroviruses are the important factor in the development of meningitis in the children of younger age. The clinical picture of enteroviral meningitis often develops gradually for 2-3 days and includes the typical syndromes: intoxication and meningeal ones. Every third patient with enterovirus infection has diarrhea and catarrhal symptoms, that’s why it is difficult to diagnose meningitis in its early stages, but it allows to assume enteroviral etiology of the disease. The meningitis of enteroviral etiology is characterized by multiple meningeal signs, while the non-enteroviral meningitis is characterized by dissociation with the prevalence of the of Kernig’s and Brudzinski’s symptoms. The analysis of the laboratory data showed that the enteroviral meningitis is characterized by low (over 50-100 cells "mixed" pleocytosis (the ratio of lymphocytes and neutrophils is about 1:1. These data can be used for differential diagnosis between enteroviral meningitis and serous meningitis of

    Full Text Available It’s introduced Lean techniques in a Clinical Laboratory to improve the operability and the efficiency in continuous processes of analysis, failsafe systems, analysis of areas of value pursuit of zero defects and reduction of waste, and it promote continuous improvement in presented difficulties in adapting to the changing needs of the healthcare environment. Whereas it is necessary to incorporate certification and accreditation, note that the adaptability of the clinical laboratory to the changing needs of physicians in obtaining analytical information is reduced. The application of an agile methodology on analytical systems can provide a line of work that allows the incorporation of planning short work cycles on equips quickly with operational autonomy on the basis of demand and respecting the accreditation requirements and flexibility to ensure adequate performance as the intercomparison of results from the different units analytics, analytical quality and turnaround times. Between 2012 and 2014, a process of analysis and improvement was applied to circuits, a 5 s system, transportation of samples, inventory of reactive and samples, motion of personal and samples, reductions of waiting and delays, overproduction, over processing, and defects of results and reports. At last it seems necessary to apply the Agile methodology to adapt to the evolving necessities in time and the different origins of the samples. It’s have used modular systems where the modules of this study are programmed with immunoassay techniques and it has reduced the operative modules depending on the required activity, ensuring the goals of turnaround times, analytic quality, service, health care continuity, and keeping up with the ISO 15189 accreditation requirements. The results of applying the concept of Lean-Agile to a modular system allows us to reduce the associated costs to the seasonal variation of the health care demand and to adapt the system to the changes on

    Laboratories need leaders who can effectively utilize the laboratories' resources, maximize the laboratories'capacity to detect disease, and advocate for laboratories in a fluctuating health care environment. To address this need, the University of Washington, USA, created the Certificate Program in Laboratory Leadership and Management in partnership with WHO Regional Office for the Eastern Mediterranean, and implemented it with 17 participants and 11 mentors from clinical and public health laboratories in 10 countries (Egypt, Iraq, Jordan, Lebanon, Morocco, Oman, Pakistan, Qatar, Saudi Arabia, and Yemen) in 2014. Designed to teach leadership and management skills to laboratory supervisors, the programme enabled participants to improve laboratory testing quality and operations. The programme was successful overall, with 80% of participants completing it and making impactful changes in their laboratories. This success is encouraging and could serve as a model to further strengthen laboratory capacity in the Region.

    To assess and refine competencies for the clinical research data management profession. Based on prior work developing and maintaining a practice standard and professional certification exam, a survey was administered to a captive group of clinical research data managers to assess professional competencies, types of data managed, types of studies supported, and necessary foundational knowledge. Respondents confirmed a set of 91 professional competencies. As expected, differences were seen in job tasks between early- to mid-career and mid- to late-career practitioners. Respondents indicated growing variability in types of studies for which they managed data and types of data managed. Respondents adapted favorably to the separate articulation of professional competencies vs foundational knowledge. The increases in the types of data managed and variety of research settings in which data are managed indicate a need for formal education in principles and methods that can be applied to different research contexts (ie, formal degree programs supporting the profession), and stronger links with the informatics scientific discipline, clinical research informatics in particular. The results document the scope of the profession and will serve as a foundation for the next revision of the Certified Clinical Data Manager TM exam. A clear articulation of professional competencies and necessary foundational knowledge could inform the content of graduate degree programs or tracks in areas such as clinical research informatics that will develop the current and future clinical research data management workforce. © The Author 2017.

  19. Review of clinical and laboratory features of human Brucellosis

    Directory of Open Access Journals (Sweden)

    Mantur B

    2007-01-01

    Full Text Available Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. Brucellosis has been an emerging disease since the discovery of Brucella melitensis by Sir David Bruce in 1887. Although many countries have eradicated B. abortus from cattle, in some areas B. melitensis and B. suis have emerged as causes of this infection in cattle, leading to human infections. Currently B. melitensis remains the principal cause of human brucellosis worldwide including India. The recent isolation of distinct strains of Brucella from marine mammals as well as humans is an indicator of an emerging zoonotic disease. Brucellosis in endemic and non-endemic regions remains a diagnostic puzzle due to misleading non-specific manifestations and increasing unusual presentations. Fewer than 10% of human cases of brucellosis may be clinically recognized and treated or reported. Routine serological surveillance is not practiced even in Brucella - endemic countries and we suggest that this should be a part of laboratory testing coupled with a high index of clinical suspicion to improve the level of case detection. The screening of family members of index cases of acute brucellosis in an endemic area should be undertaken to pick up additional unrecognised cases. Rapid and reliable, sensitive and specific, easy to perform and automated detection systems for Brucella spp. are urgently needed to allow early diagnosis and adequate antibiotic therapy in time to decrease morbidity / mortality. The history of travel to endemic countries along with exposure to animals and exotic foods are usually critical to making the clinical diagnosis. Laboratory testing is indispensable for diagnosis. Therefore alertness of clinician and close collaboration with microbiologist are essential even in endemic areas to correctly diagnose and treat this protean human infection. Existing treatment options, largely based on

    Full Text Available OBJECTIVES: To characterize the clinical, laboratory, and anthropometric profile of a sample of Brazilian patients with glycogen storage disease type I managed at an outpatient referral clinic for inborn errors of metabolism. METHODS: This was a cross-sectional outpatient study based on a convenience sampling strategy. Data on diagnosis, management, anthropometric parameters, and follow-up were assessed. RESULTS: Twenty-one patients were included (median age 10 years, range 1-25 years, all using uncooked cornstarch therapy. Median age at diagnosis was 7 months (range, 1-132 months, and 19 patients underwent liver biopsy for diagnostic confirmation. Overweight, short stature, hepatomegaly, and liver nodules were present in 16 of 21, four of 21, nine of 14, and three of 14 patients, respectively. A correlation was found between height-for-age and BMI-for-age Z-scores (r = 0.561; p = 0.008. CONCLUSIONS: Diagnosis of glycogen storage disease type I is delayed in Brazil. Most patients undergo liver biopsy for diagnostic confirmation, even though the combination of a characteristic clinical presentation and molecular methods can provide a definitive diagnosis in a less invasive manner. Obesity is a side effect of cornstarch therapy, and appears to be associated with growth in these patients.

  1. Autoimmune thyroiditis goitrogenic. Aspects of clinical and laboratorial diagnostic

    1986-01-01

    To asses the accuracy achieved by the A.C.A.T. and other clinical and laboratorial criterion in the diagnoses of T.A.I.B. we investigated twenty patients with goiter and antimicrossomal antibodies titres of 1/1.600 or more. Analysing the parameters useful in the diagnosis, we found a significant correlation between the antimicrossomal antibodies titres and the basal TSH concentration, an elevated basal TSH and an exaggerated response to TRH independent of the patient clinical status reflecting in the majority of the cases a state of subclinical hypotyroidism; an irregular appearance of the radioisotope thyroid scan and a positive response to a perchlorate discharge test. We conclude that from the parameters useful in the T.A.I.B. diagnosis, the A.C.A.T. detection mainly the antimicrossomal antibodies, is an excellent tool to detect patients with a clinical suspect of thyroid auto-immune disease and when we found high tires in a patient with goiter and an elevated basal TSH concentration we can suggest T.A.I.B. diagnosis.

    Ennis, G; Happell, B; Reid-Searl, K

    2015-10-01

    Clinical leadership is acknowledged as important to the nursing profession. While studies continue to identify its significance in contributing to positive outcomes for consumers, the role that clinical leadership has in enabling and supporting professional development in mental health nursing is poorly understood. This study utilized a grounded theory methodology to explore the characteristics clinicians consider important for clinical leadership and its significance for mental health nursing in day-to-day clinical practice. Individual face-to-face, semi-structured interviews were conducted with nurses working in mental health settings. Participants described the important role that clinical leaders play in enabling professional development of others through role modelling and clinical teaching. They describe how nurses, whom they perceive as clinical leaders, use role modelling and clinical teaching to influence the professional development of nursing staff and undergraduate nursing students. Attributes such as professionalism and honesty were seen, by participants, as enablers for clinical leaders in effectively and positively supporting the professional development of junior staff and undergraduate nurses in mental health nursing. This paper examines clinical leadership from the perspective of mental health nurses delivering care, and highlights the important role of clinical leaders in supporting professional development in mental health nursing. © 2015 John Wiley & Sons Ltd.

    An author is generally regarded as an individual "who has made substantial intellectual academic contributions to a published study". However, the extent of the contribution that laboratory medicine professionals have made as authors of research papers in high-impact medical journals remains unclear. From 1 January 2004 to 31 March 2009, 4837 original research articles appeared in the: New England Journal of Medicine, Lancet, Annals of Internal Medicine, JAMA and BMJ. Using authorship as an indicator of intellectual contribution, we analyzed articles that included laboratory medicine parameters in their titles in an observational cross-sectional study. We also extracted data regarding radiological topics that were published during the same time within the same journals. Out of 481 articles concerning laboratory medicine topics, 380 provided information on the affiliations of the authors. At least one author from an institution within the field of laboratory medicine was listed in 212 articles (55.8%). Out of 3943 co-authors, only 756 (19.2%) were affiliated with laboratory medicine institutions. Authors from laboratory medicine institutions were listed as the first, last or corresponding authors in 99 articles (26.1%). The comparative proportions for author affiliation from 55 radiology articles were significantly higher, as 72.7% (p=0.026) of articles and 24.8% (p=0.001) of authors indicated an affiliation with a radiology institution. Radiology professionals from 72.7% of the articles were listed as either the first, last or corresponding authors (pgeneral medicine journals.

    To review academic dismissals, students' rights in dismissal cases, and several key cases involving academic and disciplinary dismissals. Recent academic literature and legal precedents. Not applicable. Not applicable. Students involved in dismissals are protected under the principles of constitutional law and/or contract law, depending on whether the institution is public or private. The basis for dismissal from educational programs is either academic or disciplinary in nature. In academic dismissals, a student has failed to meet either the cognitive or the noncognitive academic standards of the program. In disciplinary dismissals, a student has violated the institutional rules governing conduct. Policies that affect progress in the program and the dismissal process should be published and distributed to students, as well as reviewed for consistency with institutional policies. The amount of documentation needed in the defense of a dismissal decision has not been specified, but, in general, more is better. Procedures are suggested as a guide to dismissals in clinical laboratory programs.

    1980-07-01

    A new urinary conduit utilizing pure vitreous carbon has been used successfully in dogs. Pure carbon appears to be inert with respect to urine and urothelium. Lack of urinary salt encrustation on the exposed surface provides a well-functioning urinary conduit for vesical drainage. Twenty-one vesicostomies were performed in dogs. Careful follow-up and histologic studies of removed specimens were done to establish the biocompatibility of pure carbon. All vesicostomies functioned well. A description of the device, protocol, and results of laboratory experimentation are outlined. The surgical procedure is explained in detail. Results encourage the clinical trial of these devices in humans. Indications include patients with neurogenic vesicla dysfunction and those with total urinary incontinence, both of which require permanent indwelling catheters.

    Dengue is endemic in more than 100 countries, giving rise to an increased number of deaths in the last five years in the South-East Asian region. We report our findings from a retrospective study of adults admitted with confirmed dengue at our institution. We studied the clinical and laboratory parameters associated with mortality in these patients. Of the 172 hospitalised patients studied, 156 (90.69 %) recovered while 16 (9.3%) died. Univariate analysis showed altered sensorium on presentation, lower haemoglobin and haematocrit levels, higher serum creatinine, higher serum transaminase and lower serum albumin levels to be significantly associated with mortality in dengue. Further, using stepwise multivariate logistic regression, altered sensorium ( P = 0.006) and hypoalbuminemia ( P = 0.013) were identified as independent predictors of mortality in dengue. Identification of these parameters early in the course of disease should prompt intensification of treatment in dengue cases.

    Chang, Ronald; Fox, Erin E; Greene, Thomas J

    2018-01-01

    BACKGROUND: Laboratory-based evidence of coagulopathy (LC) is observed in 25-35% of trauma patients, but clinically-evident coagulopathy (CC) is not well described. METHODS: Prospective observational study of adult trauma patients transported by helicopter from the scene to nine Level 1 trauma...... centers in 2015. Patients meeting predefined highest-risk criteria were divided into CC+ (predefined as surgeon-confirmed bleeding from uninjured sites or injured sites not controllable by sutures) or CC-. We used a mixed-effects, Poisson regression with robust error variance to test the hypothesis...... that abnormalities on rapid thrombelastography (r-TEG) and international normalized ratio (INR) were independently associated with CC+. RESULTS: Of 1,019 highest-risk patients, CC+ (n=41, 4%) were more severely injured (median ISS 32 vs 17), had evidence of LC on r-TEG and INR, received more transfused blood...

    Objective  To identify the prevalence of pyelonephritis during pregnancy and to analyze the clinical and laboratorial aspects, perinatal results and complications. Methods  A transversal study of 203 pregnant women who had pyelonephritis during pregnancy and whose labor took place between 2010 and 2016 at a hospital in the state of Santa Catarina, Brazil. The analysis was based on medical records as well as on the hospital's database. Clinical and laboratory conditions, antibiotics, bacterial resistance, perinatal outcomes and complications were all taken into account. The data was compared using the Mann-Whitney test and the Chi-square test. Results  A prevalence of 1.97% with pyelonephritis was evidenced, with most patients having it during the second trimester of gestation. The bacteria most commonly found in the urine cultures was Escherichia coli , in 76.6% of cases, followed by Klebsiella pneumoniae (8.7%). Ceftriaxone had the lowest bacterial resistance (only 3.5% of the cases). On the other hand, ampicillin and cephalothin presented higher bacterial resistance, 52% and 36.2%, respectively. The risk of very premature delivery was more than 50% higher in patients with pyelonephritis. Conclusion  Ampicillin and first-generation cephalosporins are associated with a higher bacterial resistance while ceftriaxone proved to have a high efficacy for the treatment of pyelonephritis due to low bacterial resistance. Patients with pyelonephritis showed a higher risk for very premature delivery (< 32 weeks). In this casuistry, there were no others significant differences in the overall perinatal outcomes when compared with the routine service series.

    Accurate antimicrobial susceptibility testing is vital for patient care and surveillance of emerging antimicrobial resistance. The National Committee for Clinical Laboratory Standards (NCCLS) outlines generally agreed upon guidelines for reliable and reproducible results. In January 1997 we surveyed 320 laboratories participating in the New York State Clinical Evaluation Program for General Bacteriology proficiency testing. Our survey addressed compliance with NCCLS susceptibility testing guidelines for bacterial species designated a problem (Staphylococcus aureus and Enterococcus species) or fastidious (Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria gonorrhoeae) organism. Specifically, we assessed compliance with guidelines for inoculum preparation, medium choice, number of disks per plate, and incubation conditions for disk diffusion tests. We also included length of incubation for S. aureus and Enterococcus species. We found overall compliance with the five characteristics listed above in 80 of 153 responding laboratories (50.6%) for S. aureus and 72 of 151 (47.7%) laboratories for Enterococcus species. The most common problem was an incubation time shortened to less than 24 h. Overall compliance with the first four characteristics was reported by 92 of 221 (41.6%) laboratories for S. pneumoniae, 49 of 163 (30.1%) laboratories for H. influenzae, and 11 of 77 (14.3%) laboratories for N. gonorrhoeae. Laboratories varied from NCCLS guidelines by placing an excess number of disks per plate. Laboratories also reported using alternative media for Enterococcus species, N. gonorrhoeae, and H. influenzae. This study demonstrates a need for education among clinical laboratories to increase compliance with NCCLS guidelines. PMID:10970381

    We report the experience from the Antiphospholipid Antibodies (aPL) Regional Consortium in northwest Italy, meant to support clinical research and foster collaboration among health professionals regarding the diagnosis and management of antiphospholipid syndrome (APS) patients. This cohort-study (APS Piedmont Cohort) was designed to register the clinical characteristics at inception and associated immunological manifestations at diagnosis (if any) of patients who strictly fulfilled the current criteria for APS, all recruited at the Piedmont and Valle d'Aosta regions. Clinical and laboratory data from 217 APS patients (171 with vascular events, 33 with pregnancy morbidity and 13 with both), from 16 centres within the geographical area were collected. Venous thrombosis was recorded in 45.6% of patients, arterial thrombosis in 35%, small-vessel thrombosis in 1.12% and mixed arterial and venous thrombosis in the remaining 19.4% of the cases. Pregnancy morbidity included 19 patients with unexplained fetal death beyond the 10th week of pregnancy, 17 with premature birth before the 34th week and 10 with three or more unexplained spontaneous abortions before the 10th week of gestation. This consortium represents an instrument by which to audit clinical practice, to provide counselling to local centres and to sustain future basic and clinical APS research.

    Since ISO 15189:2003 was published, the accreditation program of clinical laboratories based on ISO 15189 has been introduced in many countries, except for those in USA where all clinical laboratories must be required to follow the federal law, CLIA'88. It will certainly help the accredited clinical laboratories improve their quality and competence. In relation to the activity of JCTLM, reference measurement laboratories will be accredited, based on ISO 15195 which is now under its review and amendment by ISO/TC212/WG2. In Japan, JCCLS (Japanese Committee for Clinical Laboratory Standards) and JAB (Japan Accreditation Board for Conformity Assessment) cojointly started the accreditation program for clinical laboratories, based on ISO 15189:2003, and a total of 15 laboratories including university hospitals, community hospitals and independent clinical laboratories have been accredited up until the end of 2006.

  12. Guiding role of typical cases in clinical training for ophthalmology professional degree graduate students

    2014-05-01

    Full Text Available With the change of the concept of graduate enrollment, the recruiting proportion of clinical medicine professional degree graduate students is more and more, and the training of professional degree graduate students is increasingly focusing on practical. In our experience in clinical training for ophthalmology professional degree graduate students, increasing the ward clinical practice time is important. For particular emphasis on the guiding role of the typical cases, each professional group combined their professional characteristics of the typical cases to instruct the graduate students, training their clinical diagnosis and treatment ability, training their microsurgical techniques. From clinical medical writing, record summary, literature review, professional degree graduate students could expand their knowledge structure, practice their thesis writing ability. Based on the typical cases, expansion of knowledge coverage, they could improve the ability of diagnosis and treatment for special disease cases. In this rigorous training system, professional degree graduate students can learn by analogy, and focus on typical cases to get the most intuitive panoramic understanding of the diseases, with a minimum of time to master the most clinical knowledge, to enrich clinical experience, and to lay the foundation for future work in the assessment.

  13. Custom software development for use in a clinical laboratory.

    Science.gov (United States)

    Sinard, John H; Gershkovich, Peter

    2012-01-01

    In-house software development for use in a clinical laboratory is a controversial issue. Many of the objections raised are based on outdated software development practices, an exaggeration of the risks involved, and an underestimation of the benefits that can be realized. Buy versus build analyses typically do not consider total costs of ownership, and unfortunately decisions are often made by people who are not directly affected by the workflow obstacles or benefits that result from those decisions. We have been developing custom software for clinical use for over a decade, and this article presents our perspective on this practice. A complete analysis of the decision to develop or purchase must ultimately examine how the end result will mesh with the departmental workflow, and custom-developed solutions typically can have the greater positive impact on efficiency and productivity, substantially altering the decision balance sheet. Involving the end-users in preparation of the functional specifications is crucial to the success of the process. A large development team is not needed, and even a single programmer can develop significant solutions. Many of the risks associated with custom development can be mitigated by a well-structured development process, use of open-source tools, and embracing an agile development philosophy. In-house solutions have the significant advantage of being adaptable to changing departmental needs, contributing to efficient and higher quality patient care.

    The only significant advances in blood-taking in 25 years have been the disposable needle and evacuated blood-drawing tube. With the exception of a few isolated barcode experiments, most sample-tracking is performed through handwritten or computer-printed labels. Attempts to reduce the hazards of centrifugation have resulted in air-tight lids or chambers, the use of which is time-consuming and cumbersome. Most commonly used clinical analyzers require serum or plasma, distributed into specialized containers, unique to that analyzer. Aliquots for different tests are prepared by handpouring or pipetting. Moderate to large clinical laboratories perform so many different tests that even multi-analyzers performing multiple analyses on a single sample may account for only a portion of all tests ordered for a patient. Thus several aliquots of each specimen are usually required. We have developed a proprietary serial centrifuge and blood-collection tube suitable for incorporation into an automated or robotic sample-handling system. The system we propose is (a) safe--avoids or prevents biological danger to the many "handlers" of blood; (b) small--minimizes the amount of sample taken and space required to adapt to the needs of satellite and mobile testing, and direct interfacing with analyzers; (c) serial--permits each sample to be treated according to its own "merits," optimizes throughput, and facilitates flexible automation; and (d) smart--ensures quality results through monitoring and intelligent control of patient identification, sample characteristics, and separation process.

    Kim, Gungu; Kim, Gibbeum; Na, Wondo

    2016-01-01

    This brief communication introduced a systematic way to find a professional audiology clinic developed for patients and professionals by the American Academy of Audiology, American Speech-Language-Hearing Association, and Healthy Hearing. Patients can access each organization's website to find professionals and/or clinics based on criteria such as location, hours, special areas, types of service, reviews and rating by previous patients, and kinds of insurance accepted. Such a system may protect the patients from information overload, guarantee accurate information, and help them find themselves professional audiologists who can assist them. We expect professional organizations to adopt this system as soon as possible and link hearing-impaired patients with professional audiologists in Korea. PMID:27626086

    Burning mouth syndrome is a chronic and persistent painful condition characterized by burning sensation in the oral mucosa. We investigated the etiological factors of patients presented with the history of burning in the mouth who admitted our outpatient clinics over the 8-years period and who had no underlying identifiable local factors. We also tried to determine their demographic and clinical characteristics. Our aim was to investigate the association between burning mouth and psychiatric disorders such as depression and anxiety, chronic diseases like diabetes mellitus (DM) and other laboratory studies in patients complaining of solely burning in the mouth. The study included patients with the history of burning in mouth who presented in our outpatient clinic between 2005 and 2012. They were evaluated by a neurologist, a psychiatrist, an internist, and a dentist. Complete blood counts, biochemical analysis and cranial magnetic resonance imaging (MRI) were performed for all patients. A total of 26 (22 (84%) females, 4 (15%) males; mean age 55.9 years) patients were enrolled in this study. Five (19.2%) of the patients had depression, 2 (7.7%) had anxiety disorder, 2 (7.7%) had diabetes mellitus, 8 (30%) had B12 vitamin deficiency, 3 (11.5%) had decreased ferritin levels in blood, and 1 (3.8%) had folic acid deficiency. Cranial MRI of all patients were normal. Nine patients (34.6%) had no etiological causes. A multidisciplinary approach in the management of burning mouth and establishment of common criteria for the diagnosis would provide insight into the underlying pathophysiological mechanism.

    What is the recognition of clinical embryology and the current status of clinical embryologists in European countries, regarding educational levels, responsibilities and workload, and need for a formal education in assisted reproductive technology (ART)? It is striking that the profession of clinical embryology, almost 40 years after the introduction of IVF, is still not officially recognized in most European countries. Reproductive medicine has developed into a sophisticated multidisciplinary medical branch since the birth of Louise Brown 37 years ago. The European Board & College of Obstetrics and Gynaecology (EBCOG) has recognized reproductive medicine as a subspeciality and has developed a subspeciality training for gynaecologists in collaboration with the European Society for Human Reproduction and Embryology (ESHRE). However, nothing similar exists for the field of clinical embryology or for clinical embryologists. A questionnaire about the situation in clinical embryology in the period of 2012-2013 in the respective European country was sent to ESHRE National representatives (basic scientists only) in December 2013. At this time, 28 European countries had at least one basic scientist in the ESHRE Committee of National Representatives. The survey consisted of 46 numeric, dichotomous (yes/no) or descriptive questions. Answers were obtained from 27 out of 28 countries and the data were tabulated. Data about the numbers of 'ESHRE Certified Embryologists' were taken from the ESHRE Steering Committee for Embryologist Certification. In 2012, more than 7000 laboratory staff from 1349 IVF clinics in 27 European countries performed over 700 000 fresh and frozen ART cycles. Despite this, clinical embryology is only recognized as an official profession in 3 out of 27 national health systems. In most countries clinical embryologists need to be registered under another profession, and have limited possibilities for organized education in clinical embryology. Mostly they

    To conduct a situational analysis of patient safety culture in public laboratories in the Spanish National Health System and to determine the clinical governance variables that most strongly influence patient safety. A descriptive cross-sectional study was carried out, in which a Survey of Patient Safety in Clinical Laboratories was addressed to workers in 26 participating laboratories. In this survey, which consisted of 45 items grouped into 6 areas, scores were assigned on a scale from 0 to 100 (where 0 is the lowest perception of patient safety). Laboratory managers were asked specific questions about quality management systems and technology. The mean scores for the 26 participating hospitals were evaluated, and the following results observed: in 4of the 6areas, the mean score was higher than 70 points. In the third area (equipment and resources) and the fourth area (working conditions), the scores were lower than 60 points. Every hospital had a digital medical record system. This 100% level of provision was followed by that of an electronic request management system, which was implemented in 82.6% of the hospitals. The results obtained show that the culture of security is homogeneous and of high quality in health service laboratories, probably due to the steady improvement observed. However, in terms of clinical governance, there is still some way to go, as shown by the presence of weaknesses in crucial dimensions of safety culture, together with variable levels of implementation of fail-safe technologies and quality management systems.

    I propose a postgraduate common clinical training program to be provided by the department of laboratory medicine in our prefectural medical university hospital. The program has three purposes: first, mastering basic laboratory tests; second, developing the skills necessary to accurately interpret laboratory data; third, learning specific techniques in the field of laboratory medicine. For the first purpose, it is important that medical trainees perform testing of their own patients at bedside or in the central clinical laboratory. When testing at the central clinical laboratory, instruction by expert laboratory technicians is helpful. The teaching doctors in the department of laboratory medicine are asked to advise the trainees on the interpretation of data. Consultation will be received via interview or e-mail. In addition, the trainees can participate in various conferences, seminars, and meetings held at the central clinical laboratory. Finally, in order to learn specific techniques in the field of laboratory medicine, several special courses lasting a few months will be prepared. I think this program should be closely linked to the training program in internal medicine.

    Clinical empathy, i.e. the ability of physicians to adopt patient perspective, is an essential component of care, which depends in part on empathic concern, i.e. compassionate emotions felt for others. However, too much empathic concern can be challenging for physicians. Aim of this study was to examine physician practice characteristics that could explain clinical empathy beyond empathic concern. We were also interested in testing whether professional reflective activities, such as Balint group attendance or clinical supervision, might make clinical empathy less dependent on empathic concern. A total of 295 French general practitioners (response rate of 37%) completed self-reported questionnaires on empathic concern and clinical empathy, using the Toronto empathy questionnaire (TEQ) and the Jefferson scale of physician empathy (JSPE), respectively. We also recorded information on their professional practice: professional experience, duration of consultations, and participation in Balint groups or being a clinical supervisor. Hierarchical regression analyses were carried out with clinical empathy as dependent variable. Empathic concern was an important component of clinical empathy variance. The physician practice characteristics 'consultation length' and 'being a Balint attendee or a supervisor,' but not 'clinical experience' made a significant and unique contribution to clinical empathy beyond that of empathic concern. Participating to one reflective activity (either Balint group attendance or clinical supervision) made clinical empathy less dependent on empathic concern. Working conditions such as having enough consultation time and having the opportunity to attend a professional reflective activity support the maintenance of clinical empathy without the burden of too much empathic concern.

    Full Text Available Objectives: To characterize the clinical, laboratory, and anthropometric profile of a sample of Brazilian patients with glycogen storage disease type I managed at an outpatient referral clinic for inborn errors of metabolism. Methods: This was a cross-sectional outpatient study based on a convenience sampling strategy. Data on diagnosis, management, anthropometric parameters, and follow-up were assessed. Results: Twenty-one patients were included (median age 10 years, range 1–25 years, all using uncooked cornstarch therapy. Median age at diagnosis was 7 months (range, 1–132 months, and 19 patients underwent liver biopsy for diagnostic confirmation. Overweight, short stature, hepatomegaly, and liver nodules were present in 16 of 21, four of 21, nine of 14, and three of 14 patients, respectively. A correlation was found between height-for-age and BMI-for-age Z-scores (r = 0.561; p = 0.008. Conclusions: Diagnosis of glycogen storage disease type I is delayed in Brazil. Most patients undergo liver biopsy for diagnostic confirmation, even though the combination of a characteristic clinical presentation and molecular methods can provide a definitive diagnosis in a less invasive manner. Obesity is a side effect of cornstarch therapy, and appears to be associated with growth in these patients.

    Ensuring quality has become a daily requirement in laboratories. In haemostasis, even more than in other disciplines of biology, quality is determined by a pre-analytical step that encompasses all procedures, starting with the formulation of the medical question, and includes patient preparation, sample collection, handling, transportation, processing, and storage until time of analysis. This step, based on a variety of manual activities, is the most vulnerable part of the total testing process and is a major component of the reliability and validity of results in haemostasis and constitutes the most important source of erroneous or un-interpretable results. Pre-analytical errors may occur throughout the testing process and arise from unsuitable, inappropriate or wrongly handled procedures. Problems may arise during the collection of blood specimens such as misidentification of the sample, use of inadequate devices or needles, incorrect order of draw, prolonged tourniquet placing, unsuccessful attempts to locate the vein, incorrect use of additive tubes, collection of unsuitable samples for quality or quantity, inappropriate mixing of a sample, etc. Some factors can alter the result of a sample constituent after collection during transportation, preparation and storage. Laboratory errors can often have serious adverse consequences. Lack of standardized procedures for sample collection accounts for most of the errors encountered within the total testing process. They can also have clinical consequences as well as a significant impact on patient care, especially those related to specialized tests as these are often considered as "diagnostic". Controlling pre-analytical variables is critical since this has a direct influence on the quality of results and on their clinical reliability. The accurate standardization of the pre-analytical phase is of pivotal importance for achieving reliable results of coagulation tests and should reduce the side effects of the influence

    Nursing graduates acquire their nursing values by professional socialization. Mentoring is a crucial support mechanism for these novice nurses, yet little is known about the model C clinical nurse leader graduate and the effects of mentoring. This investigation examined how mentoring affected the development of professional nursing values in the model C clinical nurse leader graduate. A longitudinal design was used to survey model C clinical nurse leader graduates before and after graduation to determine how different types of mentoring relationships influenced professional values. Demographic surveys documented participant characteristics and the Nurses Professional Values Scale - Revised (NPVS-R) assessed professional nursing values. Mean NPVS-R scores increased after graduation for the formally mentored participants, while the NPVS-R scores decreased or remained unchanged for the other mentoring groups. However, no significant difference was found in NPVS-R scores over time (p = .092) or an interaction between the NPVS-R scores and type of mentoring relationships (p = .09). These results suggest that model C clinical nurse leader graduate participants experiencing formal mentoring may develop professional nursing values more than their colleagues. Formal mentoring relationships are powerful and should be used to promote professional values for model C clinical nurse leader graduates. © 2018 John Wiley & Sons Ltd.

  8. Assessing Professionalism: A Theoretical Framework for Defining Clinical Rotation Assessment Criteria.

    Science.gov (United States)

    Armitage-Chan, Elizabeth

    Although widely accepted as an important graduate competence, professionalism is a challenging outcome to define and assess. Clinical rotations provide an excellent opportunity to develop student professionalism through the use of experiential learning and effective feedback, but without appropriate theoretical frameworks, clinical teachers may find it difficult to identify appropriate learning outcomes. The adage "I know it when I see it" is unhelpful in providing feedback and guidance for student improvement, and criteria that are more specifically defined would help students direct their own development. This study sought first to identify how clinical faculty in one institution currently assess professionalism, using retrospective analysis of material obtained in undergraduate teaching and faculty development sessions. Subsequently, a faculty workshop was held in which a round-table type discussion sought to develop these ideas and identify how professionalism assessment could be improved. The output of this session was a theoretical framework for teaching and assessing professionalism, providing example assessment criteria and ideas for clinical teaching. This includes categories such as client and colleague interaction, respect and trust, recognition of limitations, and understanding of different professional identities. Each category includes detailed descriptions of the knowledge, skills, and behaviors expected of students in these areas. The criteria were determined by engaging faculty in the development of the framework, and therefore they should represent a focused development of criteria already used to assess professionalism, and not a novel and unfamiliar set of assessment guidelines. The faculty-led nature of this framework is expected to facilitate implementation in clinical teaching.

    2015-01-01

    The cost, speed, and quality are the three important factors recently indicated by the Ministry of Health, Labour and Welfare (MHLW) for the purpose of accelerating clinical studies. Based on this background, the importance of laboratory tests is increasing, especially in the evaluation of clinical study participants' entry and safety, and drug efficacy. To assure the quality of laboratory tests, providing high-quality laboratory tests is mandatory. For providing adequate quality assurance in laboratory tests, quality control in the three fields of pre-analytical, analytical, and post-analytical processes is extremely important. There are, however, no detailed written requirements concerning specimen collection, handling, preparation, storage, and shipping. Most laboratory tests for clinical studies are performed onsite in a local laboratory; however, a part of laboratory tests is done in offsite central laboratories after specimen shipping. As factors affecting laboratory tests, individual and inter-individual variations are well-known. Besides these factors, standardizing the factors of specimen collection, handling, preparation, storage, and shipping, may improve and maintain the high quality of clinical studies in general. Furthermore, the analytical method, units, and reference interval are also important factors. It is concluded that, to overcome the problems derived from pre-analytical processes, it is necessary to standardize specimen handling in a broad sense.

    2009-05-01

    Full Text Available Abstract Background Clinical experience has traditionally been highly valued in medical education and clinical healthcare. On account of its multi-faceted nature, clinical experience is mostly difficult to articulate, and is mainly expressed in clinical situations as professional approaches. Due to retirement, hospitals in Scandinavia will soon face a substantial decrease in the number of senior specialist doctors, and it has been discussed whether healthcare will suffer an immense loss of experienced-based knowledge when this senior group leaves the organization. Both senior specialists and junior colleagues are often involved in clinical education, but the way in which these two groups vary in professional approaches and contributions to clinical education has not been so well described. Cognitive psychology has contributed to the understanding of how experience may influence professional approaches, but such studies have not included the effect of differences in position and responsibilities that junior and senior doctors hold in clinical healthcare. In the light of the discussion above, it is essential to describe the professional approaches of senior doctors in relation to those of their junior colleagues. This study therefore aims to describe and compare the professional approaches of junior and senior doctors when making clinical judgements. Methods Critical incident technique was used in interviews with nine senior doctors and nine junior doctors in internal medicine. The interviews were subjected to qualitative content analysis. Result Senior and junior doctors expressed a variety of professional approaches in clinical judgement as follows: use of theoretical knowledge, use of prior experience of cases and courses of events, use of ethical and moral values, meeting and communicating with the patient, focusing on available information, relying on their own ability, getting support and guidance from others and being directed by the

    Virtually all the general practices in Norway participate in the Norwegian Quality Improvement of Laboratory Services in Primary Care, NOKLUS. In order to assess and develop NOKLUS's services, it was decided to carry out an investigation in the largest participating group, general practices. In autumn 2008 a questionnaire was sent to all Norwegian general practices asking for feedback on different aspects of NOKLUS's main services: contact with medical laboratory technologists, sending of control materials, use and maintenance of practice-specific laboratory binders, courses, and testing of laboratory equipment. In addition, attitudes were elicited towards possible new services directed at assessing other technical equipment and clinical use of tests. Responses were received from 1290 of 1552 practices (83%). The great majority thought that the frequency of sending out control material should continue as at present, and they were pleased with the feedback reports and follow-up by the laboratory technologists in the counties. Even after many years of practical experience, there is still a need to update laboratory knowledge through visits to practices, courses, and written information. Practices also wanted quality assurance of blood pressure meters and spirometers, and many doctors wanted feedback on their use of laboratory tests. Services regarding quality assurance of point-of-care tests, guidance, and courses should be continued. Quality assurance of other technical equipment and of the doctor's clinical use of laboratory tests should be established as part of comprehensive quality assurance.

    Patient safety is an increasingly visible and important mission for clinical laboratories. Attention to improving processes related to patient identification and specimen labeling is being paid by accreditation and regulatory organizations because errors in these areas that jeopardize patient safety are common and avoidable through improvement in the total testing process. To assess patient identification and specimen labeling improvement after multiple implementation projects using longitudinal statistical tools. Specimen errors were categorized by a multidisciplinary health care team. Patient identification errors were grouped into 3 categories: (1) specimen/requisition mismatch, (2) unlabeled specimens, and (3) mislabeled specimens. Specimens with these types of identification errors were compared preimplementation and postimplementation for 3 patient safety projects: (1) reorganization of phlebotomy (4 months); (2) introduction of an electronic event reporting system (10 months); and (3) activation of an automated processing system (14 months) for a 24-month period, using trend analysis and Student t test statistics. Of 16,632 total specimen errors, mislabeled specimens, requisition mismatches, and unlabeled specimens represented 1.0%, 6.3%, and 4.6% of errors, respectively. Student t test showed a significant decrease in the most serious error, mislabeled specimens (P patient safety projects. Trend analysis demonstrated decreases in all 3 error types for 26 months. Applying performance-improvement strategies that focus longitudinally on specimen labeling errors can significantly reduce errors, therefore improving patient safety. This is an important area in which laboratory professionals, working in interdisciplinary teams, can improve safety and outcomes of care.

    Haemophilus influenzae which were responsible for these infections were all rated as "eradicated". Moreover, the drug, administered with or without prophylactic intentions showed complete prophylactic effects in all 27 cases tested. No side effects were observed in any of the patients. Concerning abnormal clinical laboratory results, increases in GOT were noted in 2, eosinophilia in 1, and thrombocytosis in 1, but these abnormalities were invariably mild and the normalized in 1 patient without treatment. The results suggest that FMOX is useful and safe also in neonates.

    Clinical practice is a pivotal part of nursing education. It provides students with the opportunity to put the knowledge and skills they have acquired from lectures into practice with real patients, under the guidance of registered nurses. Clinical experience is also essential for shaping the nursing students' identity as future professional nurses. There is a lack of knowledge and understanding of the ways in which students learn practical skills and apply knowledge within and across different contexts, i.e. how they apply clinical skills, learnt in the laboratory in university settings, in the clinical setting. The aim of this study was therefore to explore how nursing students describe, and use, their prior experiences related to practical skills during their clinical practice. An ethnographic case study design was used. Fieldwork included participant observations (82 h), informal conversations, and interviews ( n  = 7) that were conducted during nursing students' ( n  = 17) clinical practice at an emergency department at a university hospital in Sweden. The overarching theme identified was "Learning about professional identities with respect to situated power". This encompasses tensions in students' learning when they are socialized into practical skills in the nursing profession. This overarching theme consists of three sub-themes: "Embodied knowledge", "Divergent ways of assessing and evaluating knowledge" and "Balancing approaches". Nursing students do not automatically possess the ability to transfer knowledge from one setting to another; rather, their development is shaped by their experiences and interactions with others when they meet real patients. The study revealed different ways in which students navigated tensions related to power differentials. Reflecting on actions is a prerequisite for developing and learning practical skills and professional identities. This highlights the importance of both educators' and the preceptors' roles for

    Given the importance of evidence-based guidelines in health care, we surveyed the laboratory hematology community to determine their opinions on guideline development and their experience and interest in developing clinical hematology laboratory practice guidelines. The study was conducted using an online survey, distributed to members of the International Society for Laboratory Hematology (ISLH) in 2015, with analysis of collected, anonymized responses. A total of 245 individuals participated. Most worked in clinical and/or research laboratories (83%) or industry (11%). 42% felt there were gaps in current guidelines. The majority (58%) recommended that ISLH engages its membership in guideline development. Participants differed in their familiarity with, and use of, different organizations' guidelines. Participants felt it was important to follow best practice recommendations on guideline development, including engagement of experts, statement about conflict of interests and how they were managed, systematic review and grading evidence for recommendations, identifying recommendations lacking evidence or consensus, and public input and peer review of the guideline. Moreover, it was considered important to provide guidelines free of charge. Industry involvement in guidelines was considered less important. The clinical laboratory hematology community has high expectations of laboratory practice guidelines that are consistent with recent recommendations on evidence-based guideline development. © 2016 John Wiley & Sons Ltd.

    Laboratory medicine's practitioners across the European community include medical, scientific and pharmacy trained specialists whose contributions to health and healthcare is in the application of diagnostic tests for screening and early detection of disease, differential diagnosis, monitoring, management and treatment of patients, and their prognostic assessment. In submitting a revised common syllabus for post-graduate education and training across the 27 member states an expectation is set for harmonised, high quality, safe practice. In this regard an extended 'Core knowledge, skills and competencies' division embracing all laboratory medicine disciplines is described. For the first time the syllabus identifies the competencies required to meet clinical leadership demands for defining, directing and assuring the efficiency and effectiveness of laboratory services as well as expectations in translating knowledge and skills into ability to practice. In a 'Specialist knowledge' division, the expectations from the individual disciplines of Clinical Chemistry/Immunology, Haematology/Blood Transfusion, Microbiology/ Virology, Genetics and In Vitro Fertilisation are described. Beyond providing a common platform of knowledge, skills and competency, the syllabus supports the aims of the European Commission in providing safeguards to increasing professional mobility across European borders at a time when demand for highly qualified professionals is increasing and the labour force is declining. It continues to act as a guide for the formulation of national programmes supplemented by the needs of individual country priorities.

    To make feasible and practical proposals to improve equality in the course of clinical care during the patient-provider encounter. Design: A focus group study was conducted with a qualitative approach from the perspective of reducing health inequalities in the clinic. Setting: A classroom discussion focused on equality in clinical work. Subjects: 98 professionals from several countries. Measurement tools: An analysis of the responses was performed, grouped by themes interpreted by analysts, and restructured to provide consistency and uniformity to responses given. Data were collected using a questionnaire with open answers, allowing free-form answers to three general questions that addressed improving equality from the perspective of the professional themselves, patients, and health policy managers. No saturation horizon of analytical discourses was set, to understand that from this subjective prioritization of opinion there is no possibility that discourses reached saturation. Responses were added to the 3 principal axes, recommending that professionals be aware of their discriminatory ability. Patients were asked to trust their health professionals and that they should be assigned to a professional. It was also proposed that managers provide information systems, help reduce health inequalities, and encourage professional freedom. The paper presents concrete measures to promote improved equality in clinics during the delivery of health care. Copyright © 2014 SECA. Published by Elsevier Espana. All rights reserved.

    2005-01-01

    Full Text Available The main objective of drug delivery systems is to deliver a drug effectively, specifically to the site of action and to achieve greater efficacy and minimise the toxic effects compared to conventional drugs. Amongst various carrier systems, liposomes have generated a great interest because of their versatility. Liposomes are vesicular concentric bilayered structures, which are biocompatible, biodegradable and nonimmumnogenic. They can control the delivery of drugs by targeting the drug to the site of action or by site avoidance drug delivery or by prolonged circulation of drugs. Amphotericin B (Amp B remains the drug of choice in most systemic mycoses and also as a second line treatment for Kala azar. However, its toxic effects often limit its use. Although the liposome delivery system has been tried for several drugs, only a few have been used in patients due to the slow development of necessary large-scale pharmaceutical procedures. This paper reviews the development of the technique for liposomal Amphotericin B (L-Amp-LRC-1, FungisomeTM drug delivery system in our laboratory in collaboration with the department of Biochemistry, Delhi University in India and proving the safety and efficacy of this preparation in clinical practice. It also attempts to compare the efficacy and benefits of our product for Indian patients with those of similar products and it includes facts from the publications that flowed from our work. As compared to conventional Amp B, Fungisome is infused over a much shorter period requiring a smaller volume and no premedication. It was found to be safe in patients who had developed serious unacceptable toxicity with conventional Amp B. In renal transplant patients, Fungisome did not produce any nephrotoxicity. Fungisome is effective in fungal infections resistant to fluconazole, conventional Amp B and in virgin and resistant cases of visceral leishmaniasis. The cost of any drug is of great significance, especially in India

    Full Text Available Rapid identification of yeast infections is helpful in prompt appropriate antifungal therapy. In the present study, the usefulness of chromogenic medium, slide culture technique and Vitek2 Compact (V2C has been analysed. A total of 173 clinical isolates of yeast species were included in the study. An algorithm to identify such isolates in routine clinical microbiology laboratory was prepared and followed. Chromogenic medium was able to identify Candida albicans, C. tropicalis, C. krusei, C. parapsilosis and Trichosporon asahii. Chromogenic medium was also helpful in identifying "multi-species" yeast infections. The medium was unable to provide presumptive identification of C. pelliculosa, C. utilis, C. rugosa, C. glabrata and C. hemulonii. Vitek 2 compact (V2C differentiated all pseudohypae non-producing yeast species. The algorithm followed was helpful in timely presumptive identification and final diagnosis of yeast infections, including multi-species yeast infections.

    The specialist in orthopaedic and traumatological surgery, like any other doctor, is subject to the current legal provisions while exercising their profession. Mandatory training in the medical-legal aspects of health care is essential. Claims against doctors are a reality, and orthopaedic and traumatological surgery holds first place in terms of frequency of claims according to the data from the General Council of Official Colleges of Doctors of Catalonia. Professionals must be aware of the fundamental aspects of medical professional liability, as well as specific aspects, such as defensive medicine and clinical safety. The understanding of these medical-legal aspects in the routine clinical practice can help to pave the way towards a satisfactory and safe professional career. The aim of this review is to contribute to this training, for the benefit of professionals and patients. Copyright © 2015 SECOT. Published by Elsevier Espana. All rights reserved.

    2016-12-01

    Several studies show that healthcare professionals need to communicate inter-professionally in order to manage ethical difficulties. A model of clinical ethics support (CES) inspired by Habermas' theory of discourse ethics has been developed by our research group. In this version of CES sessions healthcare professionals meet inter-professionally to communicate and reflect on ethical difficulties in a cooperative manner with the aim of reaching communicative agreement or reflective consensus. In order to understand the course of action during CES, the aim of this study was to describe the communication of value conflicts during a series of inter-professional CES sessions. Ten audio- and video-recorded CES sessions were conducted over eight months and were analyzed by using the video analysis tool Transana and qualitative content analysis. The results showed that during the CES sessions the professionals as a group moved through the following five phases: a value conflict expressed as feelings of frustration, sharing disempowerment and helplessness, the revelation of the value conflict, enhancing realistic expectations, seeing opportunities to change the situation instead of obstacles. In the course of CES, the professionals moved from an individual interpretation of the situation to a common, new understanding and then to a change in approach. An open and permissive communication climate meant that the professionals dared to expose themselves, share their feelings, face their own emotions, and eventually arrive at a mutual shared reality. The value conflict was not only revealed but also resolved.

    This paper explores some challenges of supervising clinical work of trainees, known as 'routers', who live in countries with diverse cultural, social and political traditions, and the analysts who travel to supervise them. It is written as an evolving dialogue between the authors, who explore together the effects of their own culture of origin, and in particular the legacy and values of their own training institutes on the styles and models of analytic supervision. Their dialogue is framed around the meaning of home and experiences of homesickness for analysts working away from home in an interactive field of strangeness in countries where analytical psychology is a relatively new discipline. The authors outline the findings from their own qualitative survey, where other supervisors working abroad, and those they have supervised, describe their experiences and their encounters with difference. The dialogue ends with both authors discussing what they have learned about teaching and supervising abroad, the implications for more flexible use of Jungian concepts, and how such visits have changed their clinical practice in their home countries. © 2017, The Society of Analytical Psychology.

    2016-09-01

    The study aimed to explore measurable compassion competence among nurses and to examine the relationships between nurses' compassion competence and levels of compassion satisfaction, compassion fatigue and secondary traumatic stress. Compassion is a vital asset in the nursing profession. It is necessary to explore whether compassion competence is a factor influencing professional quality of life. This study utilized a multicenter descriptive cross-sectional survey. Data were collected from 680 nurses. Professional quality of life based on nurses' general characteristics showed a significant difference in the subjects' age, marital status, education, and total clinical experience. In addition, compassion competence had a significant positive correlation with compassion satisfaction and STS, whereas it had a significant negative correlation with burnout. Compassion competence was a factor influencing compassion satisfaction and burnout in professional quality of life. Our study included nurses with at least 1 year of clinical experience in a single cultural area, which limits its widespread applicability. To improve generalizability, future studies should include clinical nurses of various races, working in diverse cultural areas and with various levels of experience (including entry-level nurses and nursing students). Compassion competence of clinical nurses was a predictive factor for professional quality of life. Hospital administrators, nurse leaders and policy makers should develop and adopt nurse-retaining strategies that focus on improving nurses' compassion competence in order to reduce their burnout. We recommend the development of educational programmes to improve nurses' compassion competence and thereby enhance their professional quality of life. © 2016 International Council of Nurses.

    We have no proper reference indicating the quality of clinical laboratory practice, which should clearly illustrates that better medical tests require more expenses. Japanese Society of Laboratory Medicine was concerned about recent difficult medical economy and issued a committee report proposing a guideline to evaluate the good laboratory practice. According to the guideline, we developed software that illustrate a cost-quality balance carried out by clinical laboratory practice. We encountered a number of controversial problems, for example, how to measure and weight each quality-related factor, how to calculate costs of a laboratory test and how to consider characteristics of a clinical laboratory. Consequently we finished only prototype software within the given period and the budget. In this paper, software implementation of the guideline and the above-mentioned problems are summarized. Aiming to stimulate these discussions, the operative software will be put on the Society's homepage for trial

    Clinicians have traditionally ordered laboratory tests using paper-based orders and requisitions. However, paper orders are becoming increasingly incompatible with the complexities, challenges, and resource constraints of our modern healthcare systems and are being replaced by electronic order entry systems. Electronic systems that allow direct provider input of diagnostic testing or medication orders into a computer system are known as Computerized Provider Order Entry (CPOE) systems. Adoption of laboratory CPOE systems may offer institutions many benefits, including reduced test turnaround time, improved test utilization, and better adherence to practice guidelines. In this review, we outline the functionality of various CPOE implementations, review the reported benefits, and discuss strategies for using CPOE to improve the test ordering process. Further, we discuss barriers to the implementation of CPOE systems that have prevented their more widespread adoption. PMID:21886891

It is a cross-sectional study conducted between the October 1(st), 2012 and the July 31, 2013 bearing on the results of 5 common examinations of clinical biochemistry, provided by 11 laboratories volunteers opening in the public and private sectors. These laboratories have analysed during the 3 cycles, 2 levels (medium and high) of serum concentration of urea, glucose, creatinine and serum aminotransferases. The performance of laboratories have been determined from the acceptable limits corresponding to the limits of total errors, defined by the French Society of Clinical Biology (SFBC). A system of internal quality control is implemented by all laboratories and 45% of them participated in international programs of external quality assessment (EQA). The rate of acceptable results for the entire study was of 69%. There was a significant difference (plaboratories engaged in a quality approach and the group with default implementation of the quality approach. Also a significant difference was observed between the laboratories of the central level and those of the peripheral level of our health system (plaboratories remains relatively unsatisfactory. It is important that the Ministry of Health put in place a national program of EQA with mandatory participation.

The difficulty is in arriving at a goal which has some evidence base to support it other than what may simply be currently achievable technically. This survey sought to establish a professional consensus on the goals and meaning of targets for laboratory turnaround time. Methods A questionnaire was circulated by the National Audit Committee to 173 lead consultants for biochemistry in the UK. The survey asked each participant to state their current target turnaround time for core investigations in a broad group of clinical settings. Each participant was also asked to provide a professional opinion on what turnaround time would pose an unacceptable risk to patient safety for each departmental category. A super majority (2/3) was selected as the threshold for consensus. Results The overall response rate was 58% ( n = 100) with a range of 49-72% across the individual Association for Clinical Biochemistry and Laboratory Medicine regions. The consensus optimal turnaround time for the emergency department was 2 h considered unacceptable. The times for general practice and outpatient department were 48 h and for Wards 12 h, respectively. Conclusions We consider that the figures provide a useful benchmark of current opinion, but clearly more empirical standards will have to develop alongside other aspects of healthcare delivery.

    Clinical practice is where student nurses are socialised into a professional role and acquire the distinct behaviour, attitudes and values of the nursing profession. Getting it right at the outset can maximise the development of a professional identity and the transmission of robust value systems. To explore the impact of the first clinical placement on the professional socialisation of adult undergraduate student nurses in the United Kingdom. Data of a longitudinal qualitative nature were collected and analysed using grounded theory. First year student nurses in hospital ward placements comprising a rural District General Hospital and a large inner city Hospital kept daily unstructured diaries for six weeks. A total of 26 undergraduate adult student nurses were purposefully sampled between 2008 and 2010 before undertaking their initial clinical placement. Data collection and analysis used grounded theory and the key question asked of the diarists 'tell me what it is like to be a first year nurse on a first placement' was theoretically adjusted during constant comparison and as the theory emerged. Ethical approval and consent was obtained. The theory of finessing incivility comprises a conceptual framework depicting how student nurses deal with professional incivility during their initial clinical placement and sustain a student identity. Being disillusioned with their role as worker rather than learner yields a sense of 'status dislocation'. Despite needing professional benevolence, they remain altruistic and seek recompense from significant others to negotiate for learning opportunities and relocate their student status. Despite the stressful transition into clinical practice rather than 'fit in', the student nurses want to belong as learners. His or her own resilience to learn nursing and be a professional student maintains their resolve, their altruism and strengthens their existing values to be benevolent towards an indifferent profession.

    2016-08-01

    Carbapenemases, enzymes that hydrolyze carbapenem-class antimicrobials, pose serious clinical and diagnostic challenges, including their recent rapid spread among members of the Enterobacteriaceae, a family with no inherent carbapenem resistance. Currently there is no one-size-fits-all method for detecting carbapenem-resistant Enterobacteriaceae (CRE) in the laboratory, nor how to differentiate carbapenemase-producers (CP) from isolates that are carbapenem-resistant via other or combined mechanisms. This article reviews definitions for CRE and CP-CRE, and discusses current phenotypic and molecular methods available to the clinical laboratory for the detection of both CP and non-CP CRE. Expert commentary: Routine evaluation of carbapenem resistance mechanism by the routine clinical laboratory are not necessary for patient care, as clinical breakpoints best predict response. However, evaluation for carbapenemase is integral to infection control efforts, and laboratories should have the capacity to do such testing, either in house or by submitting isolates to a reference laboratory.

    The LabDirector system has been developed at the Oregon Health Sciences University to support the operation of our clinical DNA analysis laboratory. Through an iterative design process which has spanned two years, we have produced a system that is both highly tailored to a clinical genetics production laboratory and flexible in its implementation, to support the rapid growth and change of protocols and methodologies in use in the field. The administrative aspects of the system are integrated with an enterprise schedule management system. The laboratory side of the system is driven by a protocol modeling and execution system. The close integration between these two aspects of the clinical laboratory facilitates smooth operations, and allows management to accurately measure costs and performance. The entire application has been designed and documented to provide utility to a wide range of clinical laboratory environments.

    Although evaluation of biochemical analytes in blood is common in veterinary practice, studies assessing the global quality of veterinary in-clinic and reference laboratory testing have not been reported. The aim of this study was to assess the quality of biochemical testing in veterinary laboratories using results obtained from analyses of 3 levels of assayed quality control materials over 5 days. Quality was assessed by comparison of calculated total error with quality requirements, determination of sigma metrics, use of a quality goal index to determine factors contributing to poor performance, and agreement between in-clinic and reference laboratory mean results. The suitability of in-clinic and reference laboratory instruments for statistical quality control was determined using adaptations from the computerized program, EZRules3. Reference laboratories were able to achieve desirable quality requirements more frequently than in-clinic laboratories. Across all 3 materials, > 50% of in-clinic analyzers achieved a sigma metric ≥ 6.0 for measurement of 2 analytes, whereas > 50% of reference laboratory analyzers achieved a sigma metric ≥ 6.0 for measurement of 6 analytes. Expanded uncertainty of measurement and ± total allowable error resulted in the highest mean percentages of analytes demonstrating agreement between in-clinic and reference laboratories. Owing to marked variation in bias and coefficient of variation between analyzers of the same and different types, the percentages of analytes suitable for statistical quality control varied widely. These findings reflect the current state-of-the-art with regard to in-clinic and reference laboratory analyzer performance and provide a baseline for future evaluations of the quality of veterinary laboratory testing. © 2012 American Society for Veterinary Clinical Pathology.

    In the late 90's there was a change in both the route of transmission and the people at risk for sporotrichosis. This zoonotic cat-man alternative transmission route elicited changes in strategies to control the epidemic. There was a progressive increase in the number of cases involving especially children and the elderly. In addition to becoming hyperendemic, uncommon clinical pictures like immunoreactive clinical presentations or severe systemic cases have emerged. New species were identified and classified through molecular tools using more virulent clinical isolates, like S. brasiliensis, compared to the environmental isolates. Likewise, different species of Sporothrix have been associated with different geographic regions. The serological and molecular techniques are used as an auxiliary tool for the diagnosis and/or for species identification, although the isolation and the identification of Sporothrix spp. in clinical specimen is still the gold standard. Currently sporotrichosis epidemics requires the knowledge of the epidemiological-molecular profile to control the disease and the specific treatment. Itraconazole, potassium iodide, terfinafine, and amphotericin B are the available drugs in Brazil to treat sporotrichosis. The drug of choice, its posology, and treatment duration vary according to the clinical presentation, the Sporothrix species, and host immune status. New treatment choices, including a vaccine, are being developed; nevertheless, more clinical trials are required to confirm its efficacy. PMID:29166494

    Full Text Available Rickets presents osteomalacia which is developed due to negative balance of calcium and / or phosphorus during growth and development. Therefore it appears only in children. The most common reason of insufficient mineralization is deficiency of vitamin D, which is necessary for inclusion of calcium in cartilage and bones. As result, proliferation of cartilage and bone tissue appears, creating calluses on typical places. Bones become soft and curve, resulting in deformities. Our present study included 86 infants, in whom, besides other diseases, clinical and laboratory signs of rickets were identified. In our study, rickets is most common (82.5% in infants older than 6 months. By clinical picture, craniotabes is present in 46.5% of cases, Harisson groove in 26.7%, rachitic bracelets in 17.4%, rachitic rosary in 17.4% and carpopedal spasms in 2.3% of cases. Leading biochemical signs of vitamin D deficient rickets is hypophosphatemia (in 87.3% of cases, normal calcemia (in 75.6% of cases and increased values of alkaline phosphatase (in 93% of cases. It has been shown that rickets in infant age may later affect higher incidence of juvenile diabetes, infection of lower respiratory tract, osteoporosis, and so on.

    Antonio José Gonçalves

    Full Text Available The medical records of 84 patients submitted to extensive thyroidectomy from January 1991 to April 1995 were reviewed and the data was analyzed in order to verify a correlation between postoperative laboratories results and physical findings suggestive of hypocalcemia. It was verified that there was hypocalcemia in 51.2 percent of the patients, of which only 18.6 percent presented symptoms. It was concluded that asymptomatic hypocalcemia is frequent in extensive thyroidectomy and a routine screening for serum calcium in the postoperative period following thyroidectomy and calcium reposition must be systematic.

    In recent years, the prevalence of in vivo molecular imaging applications has rapidly increased. Here we report on the construction of a multi-modality imaging facility in a pharmaceutical setting that is expected to further advance existing capabilities for in vivo imaging of drug distribution and the interaction with their target. The imaging instrumentation in our facility includes a microPET scanner, a four wavelength time-domain optical imaging scanner, a 9.4T/30cm MRI scanner and a SPECT/X-ray CT scanner. An electronics shop and a computer room dedicated to image analysis are additional features of the facility. The layout of the facility was designed with a central animal preparation room surrounded by separate laboratory rooms for each of the major imaging modalities to accommodate the work-flow of simultaneous in vivo imaging experiments. This report will focus on the design of and anticipated applications for our microPET and optical imaging laboratory spaces. Additionally, we will discuss efforts to maximize the daily throughput of animal scans through development of efficient experimental work-flows and the use of multiple animals in a single scanning session.

  1. ANTIFUNGAL SUSCEPTIBILITY TESTING: CURRENT ROLE FROM THE CLINICAL LABORATORY PERSPECTIVE

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Despite availability of many antifungal agents, antifungal clinical resistance occurs, perhaps as a result of an infecting organism found to be resistant in vitro to one or more antifungals tested. Thus, antifungal susceptibility testing (AFST results, if timely generated by the clinical microbiology and communicated to clinicians, can aid them in the therapeutic decision making, especially for difficult-to-treat invasive candidiasis and aspergillosis. Although recently refined AFST methods are commercially available to allow a close antifungal resistance surveillance in many clinical setting, novel assays, relying on short-time antifungal drug exposure of fungal isolates, are upcoming tools for AFST. Based on emerging technologies such as flow cytometry, MALDI-TOF mass spectrometry, and isothermal microcalorimetry, these assays could provide a reliable means for quicker and sensitive assessment of AFST.

    Full Text Available Objective: To determine the overall perception and utilization of the pharmacist managed medication therapy management (MTM clinic services, by healthcare professionals in a large, urban, university medical care setting.Methods: This was a cross-sectional, anonymous survey sent to 195 healthcare professionals, including physicians, nurses, and pharmacists at The University of Illinois Outpatient Care Center to determine their perception and utilization of the MTM clinic. The survey consisted of 12 questions and was delivered through a secure online application. Results: Sixty-two healthcare professionals (32% completed the survey. 82% were familiar with the MTM clinic, and 63% had referred patients to the clinic. Medication adherence and disease state management was the most common reason for referral. Lack of knowledge on the appropriate referral procedure was the prominent reason for not referring patients to the MTM clinic. Of the providers that were aware of MTM services, 44% rated care as ‘excellent’, 44% as ‘good’, 5% as ‘fair’, and 0% stated ‘poor’. Strengths of MTM clinic identified by healthcare providers included in-depth education to patients, close follow-up, and detailed medication reconciliation provided by MTM clinic pharmacists. Of those familiar with MTM clinic, recommendations included; increase marketing efforts to raise awareness of the MTM clinic service, create collaborative practice agreements between MTM pharmacists and physicians, and ensure that progress notes are more concise.Conclusion: In a large, urban, academic institution MTM clinic is perceived as a valuable resource to optimize patient care by providing patients with in-depth education as it relates to their prescribed medications and disease states. These identified benefits of MTM clinic lead to frequent patient referrals specifically for aid with medication adherence and disease state management.

    We performed customer satisfaction surveys for physicians and nurses regarding clinical laboratory services, and for outpatients who used phlebotomy services at a tertiary care unit level to evaluate our clinical laboratory and phlebotomy services. Thus, we wish to share our experiences with the customer satisfaction survey for clinical laboratory and phlebotomy services. Board members of our laboratory designed a study procedure and study population, and developed two types of questionnaire. A satisfaction survey for clinical laboratory services was conducted with 370 physicians and 125 nurses by using an online or paper questionnaire. The satisfaction survey for phlebotomy services was performed with 347 outpatients who received phlebotomy services by using computer-aided interviews. Mean satisfaction scores of physicians and nurses was 58.1, while outpatients' satisfaction score was 70.5. We identified several dissatisfactions with our clinical laboratory and phlebotomy services. First, physicians and nurses were most dissatisfied with the specimen collection and delivery process. Second, physicians and nurses were dissatisfied with phlebotomy services. Third, molecular genetic and cytogenetic tests were found more expensive than other tests. This study is significant in that it describes the first reference survey that offers a survey procedure and questionnaire to assess customer satisfaction with clinical laboratory and phlebotomy services at a tertiary care unit level.

    The study of disparities in minority recruitment to cancer clinical trials has focused primarily on inquiries among minority patient populations. However, clinical trial recruitment is complex and requires a broader appreciation of the multiple factors that influence minority participation. One area that has received little attention is minority recruitment training for professionals who assume various roles in the clinical trial recruitment process. Therefore, we assessed the perspectives of cancer center clinical and research personnel on their training and education needs toward minority recruitment for cancer clinical trials. Ninety-one qualitative interviews were conducted at five U.S. cancer centers among four stakeholder groups: cancer center leaders, principal investigators, referring clinicians, and research staff. Interviews were recorded and transcribed. Qualitative analyses focused on response data related to training for minority recruitment for cancer clinical trials. Four prominent themes were identified: (1) Research personnel are not currently being trained to focus on recruitment and retention of minority populations; (2) Training for minority recruitment and retention provides for a specific focus on factors influencing minority research participation; (3) Training on cultural awareness may help to bridge cultural gaps between potential minority participants and research professionals; (4) Views differ regarding the importance of research personnel training designed to focus on recruitment of minority populations. There is a lack of systematic training for minority recruitment. Many stakeholders acknowledged the benefits of minority recruitment training and welcomed training that focuses on increasing cultural awareness to increase the participation of minorities in cancer clinical trials.

As a part of this contract, EQAPOL was required to operate under Good Clinical Laboratory Practices (GCLP) that are traditionally used for laboratories conducting endpoint assays for human clinical trials. EQAPOL adapted these guidelines to the management of proficiency testing programs while simultaneously incorporating aspects of ISO/IEC 17043 which are specifically designed for external proficiency management. Over the first two years of the contract, the EQAPOL Oversight Laboratories received training, developed standard operating procedures and quality management practices, implemented strict quality control procedures for equipment, reagents, and documentation, and received audits from the EQAPOL Central Quality Assurance Unit. GCLP programs, such as EQAPOL, strengthen a laboratory's ability to perform critical assays and provide quality assessments of future potential vaccines. © 2013.

    To examine the perspectives of CRNs in the UK on their professional role identity, in order to inform the professional practice of Clinical Research Nursing. Clinical research nurses (CRN) make a significant contribution to healthcare research within the UK and internationally. However, lack of clarity about their role, and scope of practice renders their contribution within the profession and in the minds of the wider public invisible. This has implications in terms of promoting the role nurses play not only in terms of recruitment, retention, and care of research participants but also as research leaders of the future. Exploratory qualitative design using thematic analysis conducted within a realist paradigm. Participants viewed the positive aspects of their identity 'as agents of change' who were fundamental to the clinical research process. Resourcefulness and the ability to guide members of the research team were valued as key to job satisfaction. Successful navigation through the complexity of advice, support, management and leadership tasks related to their role in caring for research patients were role affirming and generated a sense of pride. However, lack of recognition, clarity of the role and career development opportunities within an identified structure undermined the CRN identity and optimism about progression in the future. Participants reported feeling invisible to colleagues within the clinical community, isolated and excluded from wider nursing groups. The study describes UK CRN practice, highlighting the positive benefits and challenges associated with the role, including the need to support professional and career development to maximise their research contribution. This study provides nurses, health care and research organisations and academic nursing educators with a broadened understanding of the professional role, identity and context of clinical research nursing practice in the United Kingdom, with recommendations to improve its

    Increasingly, stakeholders in the health care community are recognizing nursing as key to solving the nation's health care issues. This acknowledgment provides a unique opportunity for nursing to demonstrate leadership by developing clinical nurse leaders to collaborate with the multidisciplinary care team in driving evidence-based, safe quality, cost-effective health care services. One approach for nursing success is standardizing the entry-level education for nurses and developing a uniform professional development and career advancement trajectory with appropriate incentives to encourage participation. A framework to guide and provide scientific evidence of how frontline nurses can be engaged will be paramount. The model for professional excellence and career advancement provides a framework that offers a clear path for researchers to examine variables influencing nurses' professional development and career advancement in a systematic manner. Professional Excellence and Career Advancement in Nursing underscores professional preparedness of a registered nurse as central to leadership development. It also describes the elements that influence nurses' participation in professional development and career advancement under 4 main categories emphasizing mentorship and self-efficacy as essential variables.

    To evaluate (1) the state of the art in sustainability research and (2) the outcomes of professionals' adherence to guideline recommendations in medical practice. Systematic review. Searches were conducted until August 2015 in MEDLINE, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and the Guidelines International Network (GIN) library. A snowball strategy, in which reference sections of other reviews and of included papers were searched, was used to identify additional papers. Studies needed to be focused on sustainability and on professionals' adherence to clinical practice guidelines in medical care. Studies had to include at least 2 measurements: 1 before (PRE) or immediately after implementation (EARLY POST) and 1 measurement longer than 1 year after active implementation (LATE POST). The search retrieved 4219 items, of which 14 studies met the inclusion criteria, involving 18 sustainability evaluations. The mean timeframe between the end of active implementation and the sustainability evaluation was 2.6 years (minimum 1.5-maximum 7.0). The studies were heterogeneous with respect to their methodology. Sustainability was considered to be successful if performance in terms of professionals' adherence was fully maintained in the late postimplementation phase. Long-term sustainability of professionals' adherence was reported in 7 out of 18 evaluations, adherence was not sustained in 6 evaluations, 4 evaluations showed mixed sustainability results and in 1 evaluation it was unclear whether the professional adherence was sustained. (2) Professionals' adherence to a clinical practice guideline in medical care decreased after more than 1 year after implementation in about half of the cases. (1) Owing to the limited number of studies, the absence of a uniform definition, the high risk of bias, and the mixed results of studies, no firm conclusion about the sustainability of professionals' adherence to guidelines in medical practice can be drawn

    Full Text Available BACKGROUND Since 1989, several investigators have reported unusual cases of severe opportunistic infections associated with CD4 lymphocytopenia in the absence of human immunodeficiency virus infection. The cause of this condition is unknown. The Centres for Disease Control and Prevention (CDC defines Idiopathic CD4 T Lymphocytopenia (ICL as a clinical condition in which patients with depressed numbers of circulating CD4+ T-cell lymphocytes (<300 cells/μL or <20% of total T cells at a minimum of two separate time points at least 6 weeks apart, have no laboratory evidence of infection with human HIV-1 or HIV-2, or any defined immunodeficiency or therapy associated with depressed levels of CD4 T cells. The aim of the study is to analyse the clinical profile, opportunistic infections, laboratory parameters and outcome in terms of survival of patients diagnosed with ICL. MATERIALS AND METHODS Eight HIV negative patients who presented with opportunistic infections and who were diagnosed with ICL from 2007 to 2015 were included in the study. A detailed history was taken; physical examination was performed and the nature of illness with which they presented was documented. Then, CD4 and CD8 counts were done and CD4 count was repeated after a 6-week interval. The patients were followed up until discharge or death. RESULTS The mean age was 37.50±9.55 years. There were six males (75% and two females (25%. Fever was a presenting symptom among six (75% of them. Two were diagnosed to have cutaneous cryptococcosis (25%, two with invasive aspergillosis (25% and four with tuberculosis (50%. Absolute lymphocyte count was less than 1200 in seven patients (87.5%, which roughly correlates with a CD4 count of less than 200 cells/μL, among PLWHIV. The mean CD4 count was 183.63±63.74 cells/μL during the first measurement and 214.43±103.98 cells/μL during the second one. Two patients died (37.5%. None of the patients were recorded to have any form of malignancy

    Full Text Available The mucopolysaccharidoses (MPS are a heterogeneous group of inborn errors of lysosomal glycosaminoglycan (GAG metabolism. The importance of this group of disorders among the inborn errors of metabolism led us to report 19 cases. METHOD: We performed clinical, radiological, and biochemical evaluations of the suspected patients, which allowed us to establish a definite diagnosis in 19 cases. RESULTS: Not all patients showed increased GAG levels in urine; enzyme assays should be performed in all cases with strong clinical suspicion. The diagnosis was made on average at the age of 48 months, and the 19 MPS cases, after a full clinical, radiological, and biochemical study, were classified as follows: Hurler -- MPS I (1 case; Hunter -- MPS II (2 cases; Sanfilippo -- MPS III (2 cases; Morquio -- MPS IV (4 cases; Maroteaux-Lamy -- MPS VI (9 cases; and Sly -- MPS VII (1 case. DISCUSSION: The high relative frequency of Maroteaux-Lamy disease contrasts with most reports in the literature and could express a population variability.

    2009-01-01

    To identify states with laws that restrict to whom clinical laboratories may release copies of laboratory test results and to describe how these laws may affect pharmacists' ability to obtain patient laboratory test results. Researchers examined state statutes and administrative codes for all 50 states and the District of Columbia at the University of Iowa Law Library between June and July 2007. Researchers also consulted with lawyers, state Clinical Laboratory Improvement Amendments officers, and law librarians. Laws relating to the study objective were analyzed. 34 jurisdictions do not restrict the release of laboratory test results, while 17 states have laws that restrict to whom clinical laboratories can send copies of test results. In these states, pharmacists will have to use alternative sources, such as physician offices, to obtain test results. Pharmacists must consider state law before requesting copies of laboratory test results from clinical laboratories. This may be an issue that state pharmacy associations can address to increase pharmacist access to important patient information.

    Mohammadzadeh, Niloofar; Safdari, Reza

    2014-01-01

    Studies of the causes of cancer, early detection, prevention or treatment need accurate, comprehensive, and timely cancer data. The clinical laboratory provides important cancer information needed for physicians which influence clinical decisions regarding treatment, diagnosis and patient monitoring. Poor communication between health care providers and clinical laboratory personnel can lead to medical errors and wrong decisions in providing cancer care. Because of the key impact of laboratory information on cancer diagnosis and treatment the quality of the tests, lab reports, and appropriate lab management are very important. A laboratory information management system (LIMS) can have an important role in diagnosis, fast and effective access to cancer data, decrease redundancy and costs, and facilitate the integration and collection of data from different types of instruments and systems. In spite of significant advantages LIMS is limited by factors such as problems in adaption to new instruments that may change existing work processes. Applications of intelligent software simultaneously with existing information systems, in addition to remove these restrictions, have important benefits including adding additional non-laboratory-generated information to the reports, facilitating decision making, and improving quality and productivity of cancer care services. Laboratory systems must have flexibility to change and have the capability to develop and benefit from intelligent devices. Intelligent laboratory information management systems need to benefit from informatics tools and latest technologies like open sources. The aim of this commentary is to survey application, opportunities and necessity of intelligent clinical laboratory as a tool to increase cancer care management productivity.

    2018-05-24

    In the last few decades, laboratory medicine has undergone monumental changes, and laboratory technology, which has made enormous advances, now has new clinical applications thanks to the identification of a growing number of biomarkers and risk factors conducive to the promotion of predictive and preventive interventions that have enhanced the role of laboratory medicine in health care delivering. However, the paradigm shift in the past 50 years has led to a gap between laboratory and clinic, with an increased risk of inappropriateness in test request and interpretation, as well as the consolidation of analytical work in focused factories and megastructurers oriented only toward achieving greater volumes, decreasing cost per test and generating a vision of laboratory services as simple commodities. A careful historical revision of the changing models for delivering laboratory services in the United States leads to the prediction that there are several reasons for counteracting the vision of clinical laboratory as a commodity, and restoring the true nature of laboratory services as an integral part of the diagnosis and therapy process. The present study, which reports on internal and external drivers for change, proposes an integrated vision of quality in laboratory medicine.

    Full Text Available Background: Plant-origin foods are among the most important sources of food allergic reactions. An increase in the incidence of sesame seed allergy among children and adults has been reported in recent years. The aim of this preliminary study was to investigate the prevalence, importance and clinical manifestations of sesame allergy among Iranian patients.Methods: In a cross-sectional survey, 250 patients with suspected IgE-mediated food allergies completed a questionnaire and underwent skin prick tests with sesame extract as well as cross-reacting foods (walnut, soya and peanut. Total IgE and sesame-specific IgE levels were measured. Patients with positive skin test reactions and/or IgE specific for sesame without clinical symptoms were considered sensitive to sesame. The patients who also had clinical symptoms with sesame consumption were diagnosed as allergic to sesame.Results: Of the 250 patients enrolled in this study, 129 were male and 121 female, with a mean age of 11.7 years. The most common food allergens were cow's milk, egg, curry, tomato and sesame. Sesame sensitivity was found in 35 patients (14.1%. Only five patients (2% had sesame allergy. Sesame-sensitive patients had a significantly higher frequency of positive prick test to cross-reacting foods when compared to non-sensitized patients (p=0.00. The type of symptom was independent of gender and age of the patients, but urticaria and dermatitis-eczema were significantly more frequent in sensitized patients (p=0.008.Conclusions: This is the first study addressing the prevalence of sesame seed allergy in Iranian population. We found sesame to be a common and important cause of food allergy. The panel of foods recommended for use in diagnostic allergy tests should be adjusted.

    The use of calcium-phosphate casein on hypomineralized molars (molar incisor hypomineralization, MIH) has been proposed but not clinically investigated. Qualitative and quantitative effects of supplementation with a calcium-phosphate casein product on MIH molars were monitored over a period of three years. Molar replicas, minimally invasive biopsies and their SEM microphotographs, plus ESEM/EDX semi-quantitative peaks of elements present in affected enamel were evaluated. Mineralization, morphology, and porosity appeared markedly improved, with calcium and phosphate levels reaching almost normal levels at three years' follow-up. The hypothesis tested was rejected, since calcium-phosphate casein improved enamel morphology in vivo.

    Despite recent advances in diagnostic technology, microscopic examination of stool specimens remains central to the diagnosis of most pathogenic intestinal protozoa. Microscopy is, however, labor-intensive and requires a skilled technologist. New, highly sensitive diagnostic methods have been developed for protozoa endemic to developed countries, including Giardia lamblia (syn. G. intestinalis/G. duodenalis) and Cryptosporidium spp., using technologies that, if expanded, could effectively complement or even replace microscopic approaches. To date, the scope of such novel technologies is limited and may not include common protozoa such as Dientamoeba fragilis, Entamoeba histolytica, or Cyclospora cayetanensis. This minireview describes canonical approaches for the detection of pathogenic intestinal protozoa, while highlighting recent developments and FDA-approved tools for clinical diagnosis of common intestinal protozoa.

    For twenty years, mass spectrometry (MS) has emerged as a particularly powerful tool for analysis and characterization of proteins in research. It is only recently that this technology, especially MALDI-TOF-MS (Matrix Assisted Laser Desorption Ionization Time-Of-Flight) has entered the field of routine microbiology. This method has proven to be reliable and safe for the identification of bacteria, yeasts, filamentous fungi and dermatophytes. MALDI-TOF-MS is a rapid, precise and cost-effective method for identification, compared to conventional phenotypic techniques or molecular biology. Its ability to analyse whole microorganisms with few sample preparation has greatly reduced the time to identification (1-2 min). Furthermore, this technology can be used to identify bacteria directly from clinical samples as blood culture bottles or urines. Future applications will be developed in order to provide direct information concerning virulence or resistance protein markers. © 2011 médecine/sciences – Inserm / SRMS.

  12. Development and implementation of an electronic interface for complex clinical laboratory instruments without a vendor-provided data transfer interface

    Directory of Open Access Journals (Sweden)

    Gary E Blank

    2011-01-01

    Full Text Available Background: Clinical pathology laboratories increasingly use complex instruments that incorporate chromatographic separation, e.g. liquid chromatography, with mass detection for rapid identification and quantification of biochemicals, biomolecules, or pharmaceuticals. Electronic data management for these instruments through interfaces with laboratory information systems (LIS is not generally available from the instrument manufacturers or LIS vendors. Unavailability of a data management interface is a limiting factor in the use of these instruments in clinical laboratories where there is a demand for high-throughput assays with turn-around times that meet patient care needs. Materials and Methods: Professional society guidelines for design and transfer of data between instruments and LIS were used in the development and implementation of the interface. File transfer protocols and support utilities were written to facilitate transfer of information between the instruments and the LIS. An interface was created for liquid chromatography-tandem mass spectroscopy and inductively coupled plasma-mass spectroscopy instruments to manage data in the Sunquest® LIS. Results: Interface validation, implementation and data transfer fidelity as well as training of technologists for use of the interface was performed by the LIS group. The technologists were familiarized with the data verification process as a part of the data management protocol. The total time for the technologists for patient/control sample data entry, assay results data transfer, and results verification was reduced from approximately 20 s per sample to <1 s per sample. Sample identification, results data entry errors, and omissions were eliminated. There was electronic record of the technologist performing the assay runs and data management. Conclusions: Development of a data management interface for complex, chromatography instruments in clinical laboratories has resulted in rapid, accurate

  13. Has compliance with CLIA requirements really improved quality in US clinical laboratories?

    Science.gov (United States)

    Ehrmeyer, Sharon S; Laessig, Ronald H

    2004-08-02

    The Clinical Laboratory Improvement Amendments of 1988 (CLIA'88) mandate universal requirements for all U.S. clinical laboratory-testing sites. The intent of CLIA'88 is to ensure quality testing through a combination of minimum quality practices that incorporate total quality management concepts. These regulations do not contain established, objective indicators or measures to assess quality. However, there is an implicit assumption that compliance with traditionally accepted good laboratory practices--following manufacturers' directions, routinely analysing quality control materials, applying quality assurance principles, employing and assessing competent testing personnel, and participating in external quality assessment or proficiency testing (PT)--will result in improved test quality. The CLIA'88 regulations do include PT performance standards, which intentionally or unintentionally, define intra-laboratory performance. Passing PT has become a prime motivation for improving laboratory performance; it can also be used as an objective indicator to assess whether compliance to CLIA has improved intra-laboratory quality. Data from 1994 through 2002 indicate that the percentage of laboratories passing PT has increased. In addition to PT performance, subjective indicators of improved quality--frequency of inspection deficiencies, the number of government sanctions for non-compliance, and customer satisfaction--were evaluated. The results from these subjective indicators are more difficult to interpret but also seem to show improved quality in US clinical laboratories eleven years post-CLIA'88.

    This study aimed to identify the emotional intelligence skills of Turkish clinical nurses according to sociodemographic and professional variables. Emotional intelligence is "the ability of a person to comprehend self-emotions, to show empathy towards the feelings of others, and to control self-emotions in a way that enriches life." Nurses with a higher emotional intelligence level offer more efficient and professional care, and they accomplish more in their social and professional lives. We designed a descriptive cross-sectional study. The Introductory Information Form and the Bar-On emotional intelligence Inventory were used to collect data between 20th June and 20th August 2012. The study was conducted with 312 nurses from 37 hospitals located within the borders of the metropolitan municipality in Ankara. There were no significant differences between emotional intelligence scores of the nurses according to demographic variables such as age, gender, marital status, having children. Thus, sociodemographic factors did not appear to be key factors, but some professional variables did. Higher total emotional intelligence scores were observed in those who had 10 years or longer experience, who found oneself successful in professional life, who stated that emotional intelligence is an improvable skill and who previously received self-improvement training. Interpersonal skills were higher in those with a graduate degree and in nurses working in polyclinics and paediatric units. These findings indicate which groups require improvement in emotional intelligence skills and which skills need improvement. Additionally, these results provide knowledge and create awareness about emotional intelligence skills of nurses and the distribution of these skills according to sociodemographic and professional variables. Implementation of emotional intelligence improvement programmes targeting the determined clinical nursing groups by nursing administrations can help the increase in

    The high rate of turnover in nursing positions is a global problem. There have been few studies done addressing the relationship between work values and nurse turnover intention. The purpose of this study was to explore the relationship between work values, professional commitment and turnover intention among clinical nurses. A cross-sectional survey was conducted between February 1st to March 10th, 2008 on a convenience sample of nurses, all of whom had at least a half year of work experience at one of four teaching hospitals in Taiwan. A total of 289 valid responses were received, with a response rate of 96.3%. Major findings included: (1) Nurses who were older, had more years of school, had worked more years, held specific job duties, earned a higher salary, held Buddhist beliefs, or were married with two or more children presented higher work values and professional commitment and lower turnover intention; (2) As a group, total work values and professional commitment scores corresponded negatively with turnover intention scores; (3) Significant factors affecting turnover intent in clinical nurses included professional commitment, institution characteristics, Buddhist beliefs and salary. These four variables accounted for 52.2% of the variation in turnover intention. This study indicated that nurses with higher work values and professional commitment tend to exhibit less turnover intention. It is highly recommended to develop strategies to bolster the teaching of altruistic values and professional commitment in nursing education in order to reduce turnover intent. Also, further studies on the influence of religious beliefs and organizational attributes on nurse turnover intentions are also suggested.

  16. The Individualized Quality Control Plan - Coming Soon to Clinical Microbiology Laboratories Everywhere!

    Science.gov (United States)

    Anderson, Nancy

    2015-11-15

    As of January 1, 2016, microbiology laboratories can choose to adopt a new quality control option, the Individualized Quality Control Plan (IQCP), under the Clinical Laboratory Improvement Amendments of 1988 (CLIA). This voluntary approach increases flexibility for meeting regulatory requirements and provides laboratories the opportunity to customize QC for their testing in their unique environments and by their testing personnel. IQCP is an all-inclusive approach to quality based on risk management to address potential errors in the total testing process. It includes three main steps, (1) performing a risk assessment, (2) developing a QC plan, and (3) monitoring the plan through quality assessment. Resources are available from the Centers for Medicare & Medicaid Services, Centers for Disease Control and Prevention, American Society for Microbiology, Clinical and Laboratory Standards Institute, and accrediting organizations, such as the College of American Pathologists and Joint Commission, to assist microbiology laboratories implementing IQCP.

    In the early 80s, the word automation was used in the clinical laboratory setting referring only to analyzers. But in late 80s and afterwards, automation found its way into all aspects of the diagnostic process, embracing not only the analytical but also the pre- and post-analytical phase. While laboratories in the eastern world, mainly Japan, paved the way for laboratory automation, US and European laboratories soon realized the benefits and were quick to follow. Clearly, automation and robotics will be a key survival tool in a very competitive and cost-concious healthcare market. What sets automation technology apart from so many other efficiency solutions are the dramatic savings that it brings to the clinical laboratory. Further standardization will assure the success of this revolutionary new technology. One of the main difficulties laboratory managers and personnel must deal with when studying solutions to reengineer a laboratory is familiarizing themselves with the multidisciplinary and technical terminology of this new and exciting field. The present review/glossary aims at giving an overview of the most frequently used terms within the scope of laboratory automation and to put laboratory automation on a sounder linguistic basis.

    2015-01-01

    ABSTRACT Purpose: To identify professional behaviours measured in objective structured clinical examinations (OSCEs) by Canadian university physical therapy (PT) programs. Method: A cross-sectional telephone survey was conducted to review current practice and determine which OSCE items Canadian PT programs are using to measure PT students' professional behaviours. Telephone interviews using semi-structured questions were conducted with individual instructors responsible for courses that included an OSCE as part of the assessment component. Results: Nine PT programmes agreed to take part in the study, and all reported conducting at least one OSCE. The number and characteristics of OSCEs varied both within and across programs. Participants identified 31 professional behaviour items for use in an OSCE; these items clustered into four categories: communication (n=14), respect (n=10), patient safety (n=4), and physical therapists' characteristics (n=3). Conclusions: All Canadian entry-level PT programmes surveyed assess professional behaviours in OSCE-type examinations; however, the content and style of assessment is variable. The local environment should be considered when determining what professional behaviours are appropriate to assess in the OSCE context in individual programmes. PMID:25931656

    Notification of critical values to clinical staff is an important post-analytical process in all acute care clinical laboratories. No data are available however on how laboratories obtain or establish critical values, particularly in pediatric settings. This study was designed to examine and compare critical values used for pediatric patients in biochemistry laboratories in Canada and assess potential interlaboratory variability. Fourteen clinical laboratories, including two in pediatric hospitals and twelve in hospitals caring for both children and adults, participated in a survey that included 14 pre-selected STAT chemistry tests and 19 pre-selected therapeutic drug monitoring (TDM) tests. Among fourteen chemistry tests, good agreement was observed for critical values used for sodium and pH at both low and high levels within 14 participant laboratories. Significant interlaboratory variability existed for glucose critical values at the high end, magnesium at high end, and PO2 at the low end. For 19 TDM tests, the majority of laboratories did not have alert values to report values over the therapeutic level but not toxic. For critical values greater than the toxic range, significant variability existed at both trough and peak levels among laboratories surveyed. When asked to provide the source for critical values established at each site, only a limited number of laboratories identified their sources as either internal decision or published references. Although all laboratories have established and routinely use critical values to alert clinical staff, considerable variability exists in both the critical limits reported as well as the source of such values. There is a clear need for new national efforts to standardize pediatric critical value reporting and establish evidence-based critical limits for all medical laboratories across Canada.

    To ensure quality of care delivery clinical supervision has been implemented in health services. While clinical supervision of health professionals has been shown to improve patient safety, its effect on other dimensions of quality of care is unknown. The purpose of this systematic review is to determine whether clinical supervision of health professionals improves effectiveness of care and patient experience. Databases MEDLINE, PsychINFO, CINAHL, EMBASE and AMED were searched from earliest date available. Additional studies were identified by searching of reference lists and citation tracking. Two reviewers independently applied inclusion and exclusion criteria. The quality of each study was rated using the Medical Education Research Study Quality Instrument. Data were extracted on effectiveness of care (process of care and patient health outcomes) and patient experience. Seventeen studies across multiple health professions (medical (n = 4), nursing (n = 7), allied health (n = 2) and combination of nursing, medical and/or allied health (n = 4)) met the inclusion criteria. The clinical heterogeneity of the included studies precluded meta-analysis. Twelve of 14 studies investigating 38,483 episodes of care found that clinical supervision improved the process of care. This effect was most predominant in cardiopulmonary resuscitation and African health settings. Three of six studies investigating 1756 patients found that clinical supervision improved patient health outcomes, namely neurological recovery post cardiopulmonary resuscitation (n = 1) and psychological symptom severity (n = 2). None of three studies investigating 1856 patients found that clinical supervision had an effect on patient experience. Clinical supervision of health professionals is associated with effectiveness of care. The review found significant improvement in the process of care that may improve compliance with processes that are associated with enhanced patient health

    Full Text Available Brucellosis is a multisystem disease with diverse clinical presentations and involvement of the nervous system is considered to 5 to be 10% in adult patients and 1% in children. The presentations of neurobrucellosis includes meningoencephalitis, subarachnoid haemorrhage, myelitis, radiculoneuritis, intracerebral and epidural abscess, psychosis and vascular syndrome. Twenty-two patients with neurobrucellosis are described. Ten patients had meningoencephalitis, seven patients had meningitis, three patients had polyradiculopathy and one patient presented with spinal epidural abscess and one patient had brain abscess. Results of an agglutination test for Brucella in serum were positive for all patients (>1:160; eight of 15 patients had positive agglutination test in CSF. Five patients had positive blood cultures, 3 patients had positive bone marrow cultures and 2 of 15 patients had positive CSF cultures. All of cultures were Brucella Mellitensis. Antimicrobial treatment included concurrent administration of Doxycycline, Rifampin and Trimethoprim-Sulfametoxazole. Four patients received Dexamethason concurrently. In conclusion, nervous system involvement is a serious manifestation of brucellosis. As brucellosis is an endemic disease in Iran we suggest that brucellosis be investigated with neurological symptoms and signs.

    Full Text Available Objective: To evaluate a pilot of a laboratory model for relating pharmacogenetics to clinical decision making. Case Study: This pilot was undertaken and evaluated to help determine if a pharmacogenetics laboratory should be included in the core Doctor of Pharmacy curriculum. The placement of the laboratory exercise in the curriculum was determined by identifying the point in the curriculum where the students had been introduced to the chemistry of deoxyribonucleic acid (DNA as well as instructed on the chemistry of genetic variation. The laboratory included cytochrome P450 2C19 genotyping relative to the *2 variant. Twenty-four students served as the pilot group. Students provided buccal swabs as the source of DNA. Students stabilized the samples and were then provided instructions related to sample preparation, polymerase chain reaction, and gel electrophoresis. The results were reported as images of gels. Students used a reference gel image to compare their results to. Students then applied a dosing algorithm to make a “clinical decision” relative to clopidogrel use. Students were offered a post laboratory survey regarding attitudes toward the laboratory. Twenty-four students completed the laboratory with genotyping results being provided for 22 students (91.7%. Sixteen students were wild-type (*1/*1, while six students were heterozygous (*1/*2. Twenty-three students (96% completed the post laboratory survey. All 23 agreed (6, 26.1% or strongly agreed (17, 73.9% that the laboratory “had relevance and value in the pharmacy curriculum”. Conclusion: The post pilot study survey exploring a laboratory model for pharmacogenetics related to clinical decision making indicated that such a laboratory would be viewed positively by students. This model may be adopted by colleges to expand pharmacogenetics education.

    Critical value policies are used by clinical laboratories to decide when to notify caregivers of life-threatening results. Despite their widespread use, critical value policies have not been published locally. A survey was designed to determine critical value policies for haematology tests in South Africa. A survey was carried out on 136 identified laboratories across South Africa in January 2013. Of these, 36 responded. Data collected included critical value policies, critical values for haematology parameters, and critical value reporting. Of the 36 laboratories surveyed, 11.1% (n=4) were private, 33.3% (n=12) were affiliated to academic institutions and 55.6% (n=20) were peripheral or regional National Health Laboratory Service laboratories. All the laboratories confirmed that they had a critical value policy, and 83.3% of such policies were derived from local clinical opinion. Mean low and high critical limits for the most frequently listed tests were as follows: haemoglobin 20 g/dl, platelet count 1 000 ×10(9)/l, white cell count 46 ×10(9)/l, activated partial thromboplastin time >101 seconds, and international normalised ratio >6. In almost all cases critical value reporting was performed by the technologist on duty (97.2%). The majority of laboratories required that the person notified of the critical value be the doctor who ordered the test or the caregiver directly involved in the patient's care (83.3%); 73.3% of laboratories indicated that they followed an algorithm if the doctor/caregiver could not be reached. Each laboratory is responsible for establishing clinically relevant critical limits. Clinicians should be involved in developing the laboratory's critical value policy. The findings of this survey may be of value to local laboratories that are in the process of establishing or reviewing critical value policies.

    Competency assessment is critical for laboratory operations and is mandated by the Clinical Laboratory Improvement Amendments of 1988. However, no previous reports describe methods for assessing competency in patient safety. We developed and implemented a Web-based tool to assess performance of 875 laboratory staff from 29 laboratories in patient safety. Question categories included workplace culture, categorizing error, prioritization of patient safety interventions, strength of specific interventions, and general patient safety concepts. The mean score was 85.0%, with individual scores ranging from 56% to 100% and scores by category from 81.3% to 88.6%. Of the most difficult questions (laboratory technologists. Computer-based competency assessments help laboratories identify topics for continuing education in patient safety.

    Full Text Available Background: Paroxysmal nocturnal hemoglobinuria (PNH is characterized by intravascular hemolysis, marrow failure, nocturnal hemoglobinuria and thrombophila. This acquired disease caused by a deficiency of glycosylphosphatidylinositol (GPI anchored proteins on the hematopoietic cells is uncommon in the Indian population. Materials and Methods: Data of patients diagnosed with PNH in the past 1 year were collected. Clinical data (age, gender, various presenting symptoms, treatment information and follow-up data were collected from medical records. Results of relevant diagnostic tests were documented i.e., urine analysis, Ham′s test, sucrose lysis test and sephacryl gel card test (GCT for CD55 and CD59. Results: A total of 5 patients were diagnosed with PNH in the past 1 year. Presenting symptoms were hemolytic anemia (n=4 and bone marrow failure (n=1. A GCT detected CD59 deficiency in all erythrocytes in 4 patients and CD55 deficiency in 2 patients. A weak positive PNH test for CD59 was seen in 1 patient and a weak positive PNH test for CD55 was seen in 3 patients. All patients were negative by sucrose lysis test. Ham′s test was positive in two cases. Patients were treated with prednisolone and/or androgen and 1 patient with aplastic anemia was also given antithymocyte globulin. A total of 4 patients responded with a partial recovery of hematopoiesis and 1 patient showed no recovery. None of the patients received a bone marrow transplant. Conclusion: The study highlights the diagnostic methods and treatment protocols undertaken to evaluate the PNH clone in a developing country where advanced methods like flowcytometry immunophenotyping (FCMI and bone marrow transplants are not routinely available.

    2013-03-01

    Full Text Available Patients with acute stroke have better outcomes in terms of survival or regaining independence if they receive organized inpatient care in a specific setting (Stroke Unit, SU where a coordinated multidisciplinary team can ensure the best level of care. The clinical governance of an SU requires a systematic monitoring of diagnostic, clinical and therapeutic processes through a structured audit. The entire project and set up of a new SU in Bentivoglio, Italy, were based on a model that focused on multidisciplinary teamwork and clinical governance. An audit based on the Benjamin audit cycle followed every step of the set up of the new SU. Markers from national and international guidelines and from the Italian Regional Audit, together with a specific database were used. The audit showed a high level of care and a significant improvement in the majority of clinical, diagnostic and therapeutic parameters. Only a few markers (i.e. waiting times for ultrasound tomography and prescription of oral anticoagulation therapy required specific projects in order to improve the results. Our experience confirmed that a structured audit can support clinical governance of an SU by monitoring clinical processes and quality of care. Such an audit involves the whole professional team and shows the effects of any single actions. It also helps integration and co-operation among staff. Furthermore, a structured audit is a useful instrument for professional accountability for both qualitative and quantitative aspects of care.

    Hemolysis is an important clinical laboratory quality attribute that influences result reliability. To determine hemolysis identification and rejection practices occurring in clinical laboratories. We used the College of American Pathologists Survey program to distribute a Q-Probes-type questionnaire about hemolysis practices to Chemistry Survey participants. Of 3495 participants sent the questionnaire, 846 (24%) responded. In 71% of 772 laboratories, the hemolysis rate was less than 3.0%, whereas in 5%, it was 6.0% or greater. A visual scale, an instrument scale, and combination of visual and instrument scales were used to identify hemolysis in 48%, 11%, and 41% of laboratories, respectively. A picture of the hemolysis level was used as an aid to technologists' visual interpretation of hemolysis levels in 40% of laboratories. In 7.0% of laboratories, all hemolyzed specimens were rejected; in 4% of laboratories, no hemolyzed specimens were rejected; and in 88% of laboratories, some specimens were rejected depending on hemolysis levels. Participants used 69 different terms to describe hemolysis scales, with 21 terms used in more than 10 laboratories. Slight and moderate were the terms used most commonly. Of 16 different cutoffs used to reject hemolyzed specimens, moderate was the most common, occurring in 30% of laboratories. For whole blood electrolyte measurements performed in 86 laboratories, 57% did not evaluate the presence of hemolysis, but for those that did, the most common practice in 21 laboratories (24%) was centrifuging and visually determining the presence of hemolysis in all specimens. Hemolysis practices vary widely. Standard assessment and consistent reporting are the first steps in reducing interlaboratory variability among results.

  14. Advanced clinical practice for radiographers in Great Britain: professional roles, accountability and the educational provision

    International Nuclear Information System (INIS)

    Hogg, P.

    2004-01-01

    A change in British health care has resulted in a broadening of roles and responsibilities beyond 'traditional boundaries' for a range of health care professionals. This has occurred because of staff shortages (particularly within the medical profession) and the recognition that many 'non-doctor' health care staff can make safe, competent and effective contributions outside their 'normal' sphere of responsibilities. In the context of advanced clinical practice, this paper will explain the current arrangements for radiographers' roles and responsibilities, their accountability and the educational provision that underpins the development of competencies at these higher clinical levels. Some advanced roles that British radiographers perform, within their current normal responsibilities, will be identified and some British legislation and professional body guidance that make role advancement possible will be outlined. The article will conclude with an indication of the educational level at which the advanced competencies are learned and assessed. (author)

    Objectives To examine the basis of multidisciplinary teamwork. In real-world healthcare settings, clinicians often cluster in profession-based tribal silos, form hierarchies and exhibit stereotypical behaviours. It is not clear whether these social structures are more a product of inherent characteristics of the individuals or groups comprising the professions, or attributable to a greater extent to workplace factors. Setting Controlled laboratory environment with well-appointed, quiet rooms and video and audio equipment. Participants Clinical professionals (n=133) divided into 35 groups of doctors, nurses and allied health professions, or mixed professions. Interventions Participants engaged in one of three team tasks, and their performance was video-recorded and assessed. Primary and secondary measures Primary: teamwork performance. Secondary, pre-experimental: a bank of personality questionnaires designed to assess participants’ individual differences. Postexperimental: the 16-item Mayo High Performance Teamwork Scale (MHPTS) to measure teamwork skills; this was self-assessed by participants and also by external raters. In addition, external, arm's length blinded observations of the videotapes were conducted. Results At baseline, there were few significant differences between the professions in collective orientation, most of the personality factors, Machiavellianism and conservatism. Teams generally functioned well, with effective relationships, and exhibited little by way of discernible tribal or hierarchical behaviours, and no obvious differences between groups (F (3, 31)=0.94, p=0.43). Conclusions Once clinicians are taken out of the workplace and put in controlled settings, tribalism, hierarchical and stereotype behaviours largely dissolve. It is unwise therefore to attribute these factors to fundamental sociological or psychological differences between individuals in the professions, or aggregated group differences. Workplace cultures are more likely to

    Full Text Available In the last 20 years in medical laboratories, numerous activities regarding quality and accreditation system were taken. Approach to this problem in European countries is different, so the task of the Accreditation Work Group of the Confederation of European societies for clinical chemistry (EC 4 to help the efforts to harmonize this issue. External quality control in clinical-chemical laboratories imposed the need for the implementation of quality management system. »Good laboratory practice« and its principles were adopted by nominated bodies, both international and national. In the beginning, the standard ISO 9001 was applied for certification and for accreditation EN 45001 and ISO Guide 25, which are prepared for testing and calibration laboratories. Standard ISO 17025 is the successor of the previous documents and for now it is a reference for mentioned laboratories. Accreditation Work Group of the Confederation of European societies for clinical chemistry (EC 4 made an amendment of the requirements for medical laboratories, which this standard describes. Standard draft ISO 15189 was adopted on February 2003 as a final version with requirements for medical laboratories.

  17. Health and safety in clinical laboratories in developing countries: safety considerations.

    Ejilemele, A A; Ojule, A C

    2004-01-01

    Clinical laboratories are potentially hazardous work areas. Health and safety in clinical laboratories is becoming an increasingly important subject as a result of the emergence of highly infectious diseases such as hepatitis and HIV. This is even more so in developing countries where health and safety have traditionally been regarded as low priority issues, considering the more important health problems confronting the health authorities in these countries. We conducted a literature search using the medical subheadings titles on the INTERNET over a period of twenty years and summarized our findings. This article identifies hazards in the laboratories and highlights measures to make the laboratory a safer work place. It also emphasizes the mandatory obligations of employers and employees towards the attainment of acceptable safety standards in clinical laboratories in Third World countries in the face of the current HIV/AIDS epidemic in many of these developing countries especially in the sub-Saharan Africa while accommodating the increasing work load in these laboratories. Both the employer and the employee have major roles to play in the maintenance of a safe working environment. This can be achieved if measures discussed are incorporated into everyday laboratory practice.

    To search for possible early clinical associations and laboratory abnormalities in children with severe dehydration in northern Jordan. We prospectively evaluated 251 children with acute gastroenteritis. Dehydration assessment was done following a known clinical scheme. Probable clinical associations and laboratory abnormalities were examined against the preassigned dehydration status. Children with severe dehydration had significantly more hypernatremia and hyperkalemia, less isonatremia, and higher mean levels of urea, creatinine, and glucose (P dehydration. Historic clinical characteristics of patients did not correlate to dehydration degree. Serum urea, creatinine, sodium, potassium, and glucose were useful independently in augmenting clinical examination to diagnose the degree of dehydration status among children presenting with gastroenteritis. Serum urea performed the best among all. On the contrary, none of the examined historical clinical patterns could be correlated to the dehydration status. Larger and multicenter studies are needed to validate our results and to examine their impact on final outcomes.

  2. Professional autonomy in 21st century healthcare: nurses' accounts of clinical decision-making.

    Traynor, Michael; Boland, Maggie; Buus, Niels

    2010-10-01

    Autonomy in decision-making has traditionally been described as a feature of professional work, however the work of healthcare professionals has been seen as steadily encroached upon by State and managerialist forces. Nursing has faced particular problems in establishing itself as a credible profession for reasons including history, gender and a traditional subservience to medicine. This paper reports on a focus group study of UK nurses participating in post-qualifying professional development in 2008. Three groups of nurses in different specialist areas comprised a total of 26 participants. The study uses accounts of decision-making to gain insight into contemporary professional nursing. The study also aims to explore the usefulness of a theory of professional work set out by Jamous and Peloille (1970). The analysis draws on notions of interpretive repertoires and elements of narrative analysis. We identified two interpretive repertoires: 'clinical judgement' which was used to describe the different grounds for making judgements; and 'decision-making' which was used to describe organisational circumstances influencing decision-making. Jamous and Peloille's theory proved useful for interpreting instances where the nurses collectively withdrew from the potential dangers of too extreme claims for technicality or indeterminacy in their work. However, their theory did not explain the full range of accounts of decision-making that were given. Taken at face value, the accounts from the participants depict nurses as sometimes practising in indirect ways in order to have influence in the clinical and bureaucratic setting. However, a focus on language use and in particular, interpretive repertoires, has enabled us to suggest that despite an overall picture of severely limited autonomy, nurses in the groups reproduced stories of the successful accomplishment of moral and influential action.

    Digital libraries are typically used for retrieving and accessing articles in academic journals and repositories. Previous studies have been published about the performance of various biomedical research platforms, but no information is available about access preferences. A six-question survey was designed by the Italian Society of Clinical Biochemistry and Laboratory Medicine (SIBioC) using the platform Google Drive, and made available for 1 month to the members of the society. The information about the survey was published on the website of SIBioC and also disseminated by two sequential newsletters. Overall, 165 replies were collected throughout the 1-month survey availability. The largest number of replies were provided by laboratory professionals working in the national healthcare system (44.2%), followed by those working in private facilities (13.9%), university professors (12.7%) and specialization training staff (12.7%). The majority of responders published zero to one articles per year (55.2%), followed by two to five articles per year (37.6%), whereas only 7.3% published more than five articles per year. A total of 34.5% of the responders consulted biomedical research platforms on weekly basis, followed by 33.9% who did so on daily basis. PubMed/Medline was the most accessed scientific database, followed by Scopus, ISI Web of Science and Google Scholar. The impact factor was the leading reason when selecting which journal to publish in. The most consulted journals in the field of laboratory medicine were Clinical Chemistry and Laboratory Medicine and Biochimica Clinica. This survey provides useful indications about the personal inclination towards access to scientific information in our country.

    A "learning health care system", as outlined in a recent Institute of Medicine report, harnesses real-time clinical data to continuously measure and improve clinical care. However, most current efforts to understand and improve the quality of care rely on retrospective chart abstractions complied long after the provision of clinical care. To align more closely with the goals of a learning health care system, we present the novel design and initial results of the Veterans Affairs (VA) Clinical Assessment, Reporting, and Tracking (CART) program-a national clinical quality program for VA cardiac catheterization laboratories that harnesses real-time clinical data to support clinical care and quality-monitoring efforts. Integrated within the VA electronic health record, the CART program uses a specialized software platform to collect real-time patient and procedural data for all VA patients undergoing coronary procedures in VA catheterization laboratories. The program began in 2005 and currently contains data on 434,967 catheterization laboratory procedures, including 272,097 coronary angiograms and 86,481 percutaneous coronary interventions, performed by 801 clinicians on 246,967 patients. We present the initial data from the CART program and describe 3 quality-monitoring programs that use its unique characteristics-procedural and complications feedback to individual labs, coronary device surveillance, and major adverse event peer review. The VA CART program is a novel approach to electronic health record design that supports clinical care, quality, and safety in VA catheterization laboratories. Its approach holds promise in achieving the goals of a learning health care system. Published by Elsevier Inc.

    The trade of laboratory technician (TL) exposes to many risks to health, because of biological or chemical or physical exposures. But the TL occupation is constantly evolving, the techniques are constantly changing. The purpose of this article is to take stock of the occupational TL pathologies which were recently described in the literature. This is a literature review, based on Medline® and Scopus® medical databases, on publications between 01/01/2006 and 31/12/2016. The research was conducted in French and English. Only articles about TL in Hospital or Teaching Hospital were selected. Twenty-eight articles were studied. The main infectious pathology described was brucellosis and a case of meningitis was studied. The cutaneous allergies reported concerned sensitization to certain solvents. There was no allergy to latex. Musculoskeletal disorders (MSD) were studied in 4 articles. The main MSDs were low back pain and neck pain. Several articles have alerted on the occurrence of burnout syndrome (BO). However, no prevalence studies were conducted over the period studied. In conclusion, TL can present many occupational pathologies. Few articles studied the prevalence of MSD and BO.

    Data sharing through ClinVar offers a unique opportunity to identify interpretation differences between laboratories. As part of a ClinGen initiative, four clinical laboratories (Ambry, GeneDx, Partners Healthcare Laboratory for Molecular Medicine, and University of Chicago Genetic Services Laboratory) collaborated to identify the basis of interpretation differences and to investigate if data sharing and reassessment resolve interpretation differences by analyzing a subset of variants. ClinVar variants with submissions from at least two of the four participating laboratories were compared. For a subset of identified differences, laboratories documented the basis for discordance, shared internal data, independently reassessed with the American College of Medical Genetics and Genomics-Association for Molecular Pathology (ACMG-AMP) guidelines, and then compared interpretations. At least two of the participating laboratories interpreted 6,169 variants in ClinVar, of which 88.3% were initially concordant. Laboratories reassessed 242/724 initially discordant variants, of which 87.2% (211) were resolved by reassessment with current criteria and/or internal data sharing; 12.8% (31) of reassessed variants remained discordant owing to differences in the application of the ACMG-AMP guidelines. Participating laboratories increased their overall concordance from 88.3 to 91.7%, indicating that sharing variant interpretations in ClinVar-thereby allowing identification of differences and motivation to resolve those differences-is critical to moving toward more consistent variant interpretations.Genet Med advance online publication 09 March 2017.

    Nontechnical competencies identified as essential to the health professional's success include ethical behavior, interpersonal, self-management, leadership, business, and thinking competencies. The literature regarding such diverse topics, and the literature regarding "professional success" is extensive and wide-ranging, crossing educational, psychological, business, medical and vocational fields of study. This review is designed to introduce ways of viewing nontechnical competence from the psychology of human capacity to current perspectives, initiatives and needs in practice. After an introduction to the tensions inherent in educating individuals for both biomedical competency and "bedside" or "cageside" manner, the paper presents a brief overview of the major lines of inquiry into intelligence theory and how theories of multiple intelligences can build a foundation for conceptualizing professional and life skills. The discussion then moves from broad concepts of intelligence to more specific workplace skill sets, with an emphasis on professional medical education. This section introduces the research on noncognitive variables in various disciplines, the growing emphasis on competency based education, and the SKA movement in veterinary education. The next section presents the evidence that nontechnical, noncognitive or humanistic skills influence achievement in academic settings, medical education and clinical performance, as well as the challenges faced when educational priorities must be made.

    Garg, Uttam; Zhang, Yan Victoria

    2016-01-01

    Mass spectrometry (MS) has been used in research and specialized clinical laboratories for decades as a very powerful technology to identify and quantify compounds. In recent years, application of MS in routine clinical laboratories has increased significantly. This is mainly due to the ability of MS to provide very specific identification, high sensitivity, and simultaneous analysis of multiple analytes (>100). The coupling of tandem mass spectrometry with gas chromatography (GC) or liquid chromatography (LC) has enabled the rapid expansion of this technology. While applications of MS are used in many clinical areas, therapeutic drug monitoring, drugs of abuse, and clinical toxicology are still the primary focuses of the field. It is not uncommon to see mass spectrometry being used in routine clinical practices for those applications.

    Many countries are on the brink of establishing antibiotic stewardship programmes in hospitals nationwide. In a previous study we found that communication between microbiology laboratories and clinical units is a barrier to implementing efficient antibiotic stewardship programmes in Norway. We have now addressed the key communication barriers between microbiology laboratories and clinical units from a laboratory point of view. Qualitative semi-structured interviews were conducted with 18 employees (managers, doctors and technicians) from six diverse Norwegian microbiological laboratories, representing all four regional health authorities. Interviews were recorded and transcribed verbatim. Thematic analysis was applied, identifying emergent themes, subthemes and corresponding descriptions. The main barrier to communication is disruption involving specimen logistics, information on request forms, verbal reporting of test results and information transfer between poorly integrated IT systems. Furthermore, communication is challenged by lack of insight into each other's area of expertise and limited provision of laboratory services, leading to prolonged turnaround time, limited advisory services and restricted opening hours. Communication between microbiology laboratories and clinical units can be improved by a review of testing processes, educational programmes to increase insights into the other's area of expertise, an evaluation of work tasks and expansion of rapid and point-of-care test services. Antibiotic stewardship programmes may serve as a valuable framework to establish these measures. © The Author 2017.

    Musculoskeletal disorders (MSDs) are an important health problem among healthcare workers, including clinical laboratory ones. The aim of the present study was to investigate the prevalence of MSDs and individual and psychosocial risk factors among clinical laboratory workers. A cross-sectional study was carried out among 156 workers of 30 clinical laboratories in 3 towns of Iran. The Nordic questionnaire with individual and psychosocial risk factors was used to collect data. Multiple logistic regression analysis was performed. The prevalence of reported MSDs among the study population was 72.4% in the past 12 months. The most prevalent MSDs were pain in the lower back and neck; 42.7% and 33.3%, respectively. Significant relations were found between MSDs and age, gender, heavy work at home and job control (p workers were high and associated with age, gender, heavy work at home and job control. More research into measuring these factors and workplace physical demands is suggested.

    To develop a conceptual framework of the influences on medical trainees' decisions regarding requests for clinical support from a supervisor. Phase 1: members of teaching teams in internal and emergency medicine were observed during regular clinical activities (216 hours) and subsequently completed brief interviews. Phase 2: 36 in depth interviews were conducted using videotaped vignettes to probe tacit influences on decisions to request support. Data collection and analysis used grounded theory methods. Three teaching hospitals in an urban setting in Canada. 124 members of teaching teams on general internal medicine wards and in the emergency department, comprising 31 attending physicians, 57 junior and senior residents, 28 medical students, and eight nurses. Purposeful sampling to saturation was conducted. Trainees' decisions about whether or not to seek clinical support were influenced by three issues: the clinical question (clinical importance, scope of practice), supervisor factors (availability, approachability), and trainee factors (skill, desire for independence, evaluation). Trainees perceived that requesting frequent/inappropriate support threatened their credibility and used rhetorical strategies to preserve credibility. These strategies included building a case for the importance of requests, saving requests for opportune moments, making a plan before requesting support, and targeting requests to specific team members. Trainees consider not only clinical implications but also professional credibility when requesting support from clinical supervisors. Exposing the complexity of this process provides the opportunity to make changes to training programmes to promote timely supervision and provides a framework for further exploration of the impact of clinical training on quality of care of patients.

    This survey was initiated to obtain knowledge on the current situation of internal quality control (IQC) practice for tumour markers (TMs) in China. Additionally, we tried to acquire the most appropriate quality specifications. This survey was a current status survey. The IQC information had been collected via online questionnaires. All of 1821 clinical laboratories which participated in the 2016 TMs external quality assessment (EQA) programme had been enrolled. The imprecision evaluation criteria were the minimal, desirable, and optimal allowable imprecisions based on biological variations, and 1/3 total allowable error (TEa) and 1/4 TEa. A total of 1628 laboratories answered the questionnaires (89%). The coefficients of variation (CVs) of the IQC of participant laboratories varied greatly from 1% (5 th percentile) to 13% (95 th percentile). More than 82% (82 - 91%) of participant laboratories two types of CVs met 1/3 TEa except for CA 19-9. The percentiles of current CVs were smaller than cumulative CVs. A number of 1240 laboratories (76%) reported their principles and systems used. The electrochemiluminescence was the most used principle (45%) and had the smallest CVs. The performance of laboratories for TMs IQC has yet to be improved. On the basis of the obtained results, 1/3 TEa would be realistic and attainable quality specification for TMs IQC for clinical laboratories in China.

    To implement an electronic laboratory utilization management system (laboratory expert system [LES]) to provide safe and effective reductions in unnecessary clinical laboratory testing. The LES is a set of frequency filter subroutines within the Veterans Affairs hospital and laboratory information system that was formulated by an interdisciplinary medical team. Since implementing the LES, total test volume has decreased by a mean of 11.18% per year compared with our pre-LES test volume. This change was not attributable to fluctuations in outpatient visits or inpatient days of care. Laboratory cost savings were estimated at $151,184 and $163,751 for 2012 and 2013, respectively. A significant portion of these cost savings was attributable to reductions in high-volume, large panel testing. No adverse effects on patient care were reported, and mean length of stay for patients remained unchanged. Electronic laboratory utilization systems can effectively reduce unnecessary laboratory testing without compromising patient care.

    Internationally educated health professionals immigrating to other countries may experience difficulty in clinical practice, due to linguistic and cultural factors. An important element of bridging is the opportunity for internationally educated health professionals to practice in a clinical environment. To support these health professionals and their clinical instructors, a Clinical Practice Facilitator (CPF) role was created. This study aimed to examine the CPF from internationally educated health professionals and clinical instructors' perspective. A quantitative survey was conducted with two cohorts (2013 and 2015) of internationally educated physical therapists and clinical instructors who were asked about the nature of interaction with CPFs, mentor, and education roles and the benefits and challenges of the role. Thirty-five internationally educated physical therapists and 37 clinical instructors participated and were satisfied with the interaction with CPFs via face-to-face or e-mail communication. There was strong agreement (>80%) that the CPF educator role was to facilitate learner's reflection on clinical practice while the mentor role (>70%) was to answer questions, provide feedback, and investigate clinical concerns and conflicts. There was insufficient time for access to CPFs and resolution of learners' learning needs. There were differences (P = 0.04) in perspective on the benefit of the CPF in assisting with cultural differences. An innovative CPF role provided support encouragement, clinical, and professional advice. There were discordant views regarding the benefits of the CPF role in addressing cultural issues, which requires further examination.

    Clinical laboratory procedure manuals are typically maintained as word processor files and are inefficient to store and search, require substantial effort for review and updating, and integrate poorly with other laboratory information. Electronic document management systems could improve procedure management and utility. As a first step toward building such systems, we have developed a prototype electronic format for laboratory procedures using Extensible Markup Language (XML). Representative laboratory procedures were analyzed to identify document structure and data elements. This information was used to create a markup vocabulary, CLP-ML, expressed as an XML Document Type Definition (DTD). To determine whether this markup provided advantages over generic markup, we compared procedures structured with CLP-ML or with the vocabulary of the Health Level Seven, Inc. (HL7) Clinical Document Architecture (CDA) narrative block. CLP-ML includes 124 XML tags and supports a variety of procedure types across different laboratory sections. When compared with a general-purpose markup vocabulary (CDA narrative block), CLP-ML documents were easier to edit and read, less complex structurally, and simpler to traverse for searching and retrieval. In combination with appropriate software, CLP-ML is designed to support electronic authoring, reviewing, distributing, and searching of clinical laboratory procedures from a central repository, decreasing procedure maintenance effort and increasing the utility of procedure information. A standard electronic procedure format could also allow laboratories and vendors to share procedures and procedure layouts, minimizing duplicative word processor editing. Our results suggest that laboratory-specific markup such as CLP-ML will provide greater benefit for such systems than generic markup.

    The program of continuous quality improvement in clinical laboratory processes for complete blood count (CBC) was launched via the platform of Beijing Children's Hospital Group in order to improve the quality of pediatric clinical laboratories. Fifteen children's hospitals of Beijing Children's Hospital group were investigated using the method of Chinese adapted continuous quality improvement with PDCA (Plan-Do-Check-Action). The questionnaire survey and inter-laboratory comparison was conducted to find the existing problems, to analyze reasons, to set forth quality targets and to put them into practice. Then, targeted training was conducted to 15 children's hospitals and the second questionnaire survey, self examinations by the clinical laboratories was performed. At the same time, the Group's online internal quality control platform was established. Overall effects of the program were evaluated so that lay a foundation for the next stage of PDCA. Both quality of control system documents and CBC internal quality control scheme for all of clinical laboratories were improved through this program. In addition, standardization of performance verification was also improved, especially with the comparable verification rate of precision and internal laboratory results up to 100%. In terms of instrument calibration and mandatory diagnostic rates, only three out of the 15 hospitals (20%) failed to pass muster in 2014 from 46.67% (seven out of the 15 hospitals) in 2013. The abnormal data of intraday precision variance coefficients of the five CBC indicator parameters (WBC, RBC, Hb, Plt and Hct) of all the 15 laboratories accounted for 1.2% (2/165) in 2014, a marked decrease from 9.6% (14/145) in 2013. While the number of the hospitals using only one horizontal quality control object for daily quality control has dropped to three from five. The 15 hospitals organized a total of 263 times of training in 2014 from 101 times in 2013, up 160%. The quality improvement program for

    Many new innovative diagnostic approaches have been made available during the last 10 years with major impact on patient care and public health surveillance. In parallel, to enhance the cost-effectiveness of the clinical microbiology laboratories (CMLs), European laboratory professionals have streamlined their organization leading to amalgamation of activities and restructuring of their professional relationships with clinicians and public health specialists. Through this consolidation process, an operational model has emerged that combines large centralized clinical laboratories performing most tests on one high-throughput analytical platform connected to several distal laboratories dealing locally with urgent analyses at near point of care. The centralization of diagnostic services over a large geographical region has given rise to the concept of regional-scale "microbiology laboratories network." Although the volume-driven cost savings associated with such laboratory networks seem self-evident, the consequence(s) for the quality of patient care and infectious disease surveillance and control remain less obvious. In this article, we describe the range of opportunities that the changing landscape of CMLs in Europe can contribute toward improving the quality of patient care but also the early detection and enhanced surveillance of public health threats caused by infectious diseases. The success of this transformation of health services is reliant on the appropriate preparation in terms of staff, skills, and processes that would be inclusive of stakeholders. In addition, rigorous metrics are needed to set out more concrete laboratory service performance objectives and assess the expected benefits to society in terms of saving lives and preventing diseases.

Successive generations of stand-alone analysers increased analytical speed, offered the ability to test high volumes of patient specimens, and provided large assay menus. A dichotomy developed, with a group of analysers devoted to performing routine clinical chemistry tests and another group dedicated to performing immunoassays using a variety of methodologies. Development of integrated systems greatly improved the analytical phase of clinical laboratory testing and further automation was developed for pre-analytical procedures, such as sample identification, sorting, and centrifugation, and post-analytical procedures, such as specimen storage and archiving. All phases of testing were ultimately combined in total laboratory automation (TLA) through which all modules involved are physically linked by some kind of track system, moving samples through the process from beginning-to-end. A newer and very powerful, analytical methodology is liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). LC-MS/MS has been automated but a future automation challenge will be to incorporate LC-MS/MS into TLA configurations. Another important facet of automation is informatics, including middleware, which interfaces the analyser software to a laboratory information systems (LIS) and/or hospital information systems (HIS). This software includes control of the overall operation of a TLA configuration and combines analytical results with patient demographic information to provide additional clinically useful information. This review describes automation relevant to clinical chemistry, but it must be recognised that automation applies to other specialties in the laboratory, e.g. haematology, urinalysis, microbiology. It is a given that automation will continue to evolve in the clinical laboratory

    There is much uncertainty as to how fungal disease is diagnosed and characterized in patients with cystic fibrosis (CF). A 19-question anonymous electronic questionnaire was developed and distributed to ascertain current practice in clinical microbiology laboratories providing a fungal laboratory service to CF centres in the UK. Analyses of responses identified the following: (1) current UK laboratory practice, in general, follows the current guidelines, but the scope and diversity of what is currently being delivered by laboratories far exceeds what is detailed in the guidelines; (2) there is a lack of standardization of fungal tests amongst laboratories, outside of the current guidelines; (3) both the UK CF Trust Laboratory Standards for Processing Microbiological Samples from People with Cystic Fibrosis and the US Cumulative Techniques and Procedures in Clinical Microbiology (Cumitech) Guidelines 43 Cystic Fibrosis Microbiology need to be updated to reflect both new methodological innovations, as well as better knowledge of fungal disease pathophysiology in CF; (4) there is a need for clinical medicine to decide upon a stratification strategy for the provision of new fungal assays that will add value to the physician in the optimal management of CF patients; (5) there is also a need to rationale what assays should be performed at local laboratory level and those which are best served at National Mycology Reference Laboratory level; and (6) further research is required in developing laboratory assays, which will help ascertain the clinical importance of 'old' fungal pathogens, as well as 'emerging' fungal pathogens.

    Quality indicators for assessing the performance of a laboratory require a systematic and continuous approach in collecting and analyzing data. The aim of this study was to determine the frequency of errors utilizing the quality indicators in a clinical chemistry laboratory and to convert errors to the Sigma scale. Five-year quality indicator data of a clinical chemistry laboratory was evaluated to describe the frequency of errors. An 'error' was defined as a defect during the entire testing process from the time requisition was raised and phlebotomy was done until the result dispatch. An indicator with a Sigma value of 4 was considered good but a process for which the Sigma value was 5 (i.e. 99.977% error-free) was considered well controlled. In the five-year period, a total of 6,792,020 specimens were received in the laboratory. Among a total of 17,631,834 analyses, 15.5% were from within hospital. Total error rate was 0.45% and of all the quality indicators used in this study the average Sigma level was 5.2. Three indicators - visible hemolysis, failure of proficiency testing and delay in stat tests - were below 5 on the Sigma scale and highlight the need to rigorously monitor these processes. Using Six Sigma metrics quality in a clinical laboratory can be monitored more effectively and it can set benchmarks for improving efficiency.

    Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic disease, which is usually transmitted to humans by tick bites or contact with blood or other infected tissues of livestock. Patients suffering from CCHF demonstrate an extensive spectrum of clinical symptoms. As it can take considerable time from suspecting the disease in hospital until reaching a definitive diagnosis in the laboratory, understanding the clinical symptoms and laboratory findings of CCHF patients is of paramount importance for clinicians. The data were collected from patients who were referred to the Laboratory of Arboviruses and Viral Hemorrhagic Fevers at the Pasteur institute of Iran with a primary diagnosis of CCHF between 1999 and 2012 and were assessed by molecular and serologic tests. Referred patients were divided into two groups: patients with a CCHF positive result and patients with a CCHF negative result. The laboratory and clinical findings of these two groups were then compared. Two-thousand five hundred thirty-six probable cases of CCHF were referred to the laboratory, of which 871 cases (34.3%) were confirmed to be CCHF. Contact with infected humans and animals increased the CCHF infection risk (P important role in patient survival and the application of the findings of this study can prove helpful as a key for early diagnosis. © 2014 Wiley Periodicals, Inc.

    Patient care relies heavily on standardized tests performed in hospital laboratories, typically including clinical chemistry, pathology and microbiology. With the introduction of personalized medicine tremendous efforts have been made to identify new biomarkers of disease with various omics technologies, often including mass spectrometry. In order to validate new biomarkers and perform clinical studies high quality biobank samples are of key importance. In this editorial different aspects of mass spectrometry in future personalized medicine are discussed.

  13. Clinical and laboratory signs associated to serious dengue disease in hospitalized children

    Conclusions: Lethargy, abdominal distension, pleural effusion, and hypoalbuminemia were the best clinical and laboratorial markers of serious dengue disease in hospitalized children, while bleeding, severe hemorrhage, hemoconcentration and thrombocytopenia did not reach adequate diagnostic accuracy. In pediatric referral hospitals, the absence of hemoconcentration does not imply absence of plasma leakage, particularly in children with previous fluid replacement. These findings may contribute to the clinical management of dengue in children at referral hospitals.

    Inadequate volume control may be a main contributor to poor survival and high mortality in hemodialysis patients. Bioimpedance measurement has the potential to improve fluid management, but several dialysis centers lack an agreed fluid management policy, and the method has not yet been implemented. Our aim was to identify renal care professionals' perceived barriers and facilitators for use of bioimpedance in clinical practice. Qualitative data were collected through four focus group interviews with 24 renal care professionals: dieticians, nephrologists and nurses, recruited voluntarily from a nation-wide selection of hemodialysis centers, having access to a bioimpedance-device. The participants were connected to each other and a moderator via equipment for telemedicine and the sessions were recorded. The interviews were semi-structured, focusing on the participants' perceptions of use of bioimpedance in clinical practice. Thematic content analysis was performed in consecutive steps, and data were extracted by employing an inductive, interactive, comparative process. Several barriers and facilitators to the use of bioimpedance in clinical practice were identified, and a multilevel approach to examining barriers and incentives for change was found to be applicable to the ideas and categories that arose from the data. The determinants were categorized on five levels, and the different themes of the levels illustrated with quotations from the focus groups participants. Determinants for use of bioimpedance were identified on five levels: 1) the innovation itself, 2) the individual professional, 3) the patient, 4) the social context and 5) the organizational context. Barriers were identified in the areas of credibility, awareness, knowledge, self-efficacy, care processes, organizational structures and regulations. Facilitators were identified in the areas of the innovation's attractiveness, advantages in practice, and collaboration. Motivation, team processes and

    The authors have experimented the application of the Failure Mode and Effect Analysis (FMEA) technique in a clinical laboratory. FMEA technique allows: a) to evaluate and measure the hazards of a process malfunction, b) to decide where to execute improvement actions, and c) to measure the outcome of those actions. A small sample of analytes has been studied: there have been determined the causes of the possible malfunctions of the analytical process, calculating the risk probability index (RPI), with a value between 1 and 1,000. Only for the cases of RPI > 400, improvement actions have been implemented that allowed a reduction of RPI values between 25% to 70% with a costs increment of FMEA technique can be applied to the processes of a clinical laboratory, even if of small dimensions, and offers a high potential of improvement. Nevertheless, such activity needs a thorough planning because it is complex, even if the laboratory already operates an ISO 9000 Quality Management System.

    Several countries have in recent years introduced prescribed requirements for treatment and monitoring of outcomes, as well as a licensing or accreditation requirement for in vitro fertilization (IVF) clinics and their laboratories. It is commonplace for Assisted Reproductive Technology (ART) laboratories to be required to have a quality control system. However, more effective Total Quality Management systems are now being implemented by an increasing number of ART clinics. In India, it is now a requirement to have a quality management system in order to be accredited and to help meet customer demand for improved delivery of ART services. This review contains the proceedings a quality management session at the Indian Fertility Experts Meet (IFEM) 2010 and focuses on the creation of a patient-oriented best-in-class IVF laboratory.

    The increasing amount of the clinical research conducted in the primary health care has enabled extending research beyond traditional settings, but this transfer has implied some trade-offs. Health care professionals who conduct research with trusted patients require assuming the ethical standards of research and communication skills to enable patients' autonomy and freedom of choice. This study aims to measure the opinions of health professionals and patients on issues of communication in clinical research. A cross-sectional study with health care professionals and patients from primary health care centres in Barcelona (Spain). Each group completed a similar self-administered questionnaire. A Rasch model was fitted to data. After examination of goodness-of-fit, differences between groups were compared using analysis of variance, and patients' measures were calibrated to professionals' measures to compare overall mean measures. Professionals and patients found the ethical attitudes most difficult to endorse related to trust in clinical researchers and conflicts of interest. Patients' perceptions of professional ethical behaviour were significantly lower than professionals'. Different item functioning between nurses and family doctors was found in the item on seeking ethical collaboration when collaborating in clinical research. Effective knowledge of ethical norms was associated with greater perceived ethical values in clinical research and confidence in health care professionals among patients. Differences in the views of the communication process between patients and professionals could alert research boards, health care institutions and researchers to the need for greater transparency, trust and ethical instruction when patients are involved in clinical research. © 2015 John Wiley & Sons, Ltd.

    This study evaluated the relationship between 111 In-labeled leukocyte scintigraphy and clinical information and laboratory findings in 24 patients with bone infection and 35 patients with abdominal infection. Fifty-nine scintigrams were retrospectively reviewed and classified into positive or negative results. As the laboratory findings, C-reactive protein (CRP) level, erythrocyte sedimentation rate (ESR) at 60 minutes, and peripheral blood leukocyte counts (WBCC) were evaluated. Clinical information such as presence of fever and administration of antibiotics was also compared. No significant relationship between the scintigraphic results and clinical as well as laboratory findings was observed in bone infection patients. CRP levels in positive scintigraphic patients were significantly higher than those in negative scintigraphic patients in the abdominal infection group, otherwise the other indices were not correlated with the scintigraphic results. A few patients with slightly increased CRP (mostly chronic cases) did not show positive scintigrams, suggesting an increased false negative rate of leukocyte scintigraphy in such circumstances. These results suggest that it is inappropriate to determine the application of leukocyte scintigraphy depending on clinical as well as laboratory findings, and leukocyte scintigraphy would yield additional information different from other indices when evaluating inflammatory foci.

    Patient Safety Monitoring in International Laboratories (JHU-SMILE) is a resource at Johns Hopkins University that supports and monitors laboratories in National Institutes of Health-funded international clinical trials. To determine the impact of the JHU-SMILE quality assurance scheme in sub-Saharan African laboratories, we reviewed 40 to 60 months of external quality assurance (EQA) results of the College of American Pathologists (CAP) in these laboratories. We reviewed the performance of 8 analytes: albumin, alanine aminotransferase, creatinine, sodium, WBC, hemoglobin, hematocrit, and the human immunodeficiency virus antibody rapid test. Over the 40- to 60-month observation period, the sub-Saharan laboratories had a 1.63% failure rate, which was 40% lower than the 2011 CAP-wide rate of 2.8%. Seventy-six percent of the observed EQA failures occurred in 4 of the 21 laboratories. These results demonstrate that a system of remote monitoring, feedback, and audits can support quality in low-resource settings, even in places without strong regulatory support for laboratory quality.

    Despite the fact that Ethiopia has scale up antiretroviral treatment (ART) program, little is known about the patient satisfaction with ART monitoring laboratory services in health facilities. We therefore aimed to assess patient satisfaction with laboratory services at ART clinics in public hospitals. Hospital based, descriptive cross sectional study was conducted from October to November 2010 among clients attending in nine public hospitals ART clinics in Addis Ababa Ethiopia. Patients' satisfaction towards laboratory services was assessed using exit interview structured questionnaire. Data were coded and entered using EPI info 2002 (Centers for Disease Control and Prevention Atlanta, GA) and analyzed using SPSS version 15 software (SPSS INC, Chicago, IL, USA). A total of 406 clients were involved in the study. Of these 255(62.8%) were females. The overall satisfaction rate for ART monitoring laboratory services was (85.5%). Patients were satisfied with measures taken by health care providers to keep confidentiality and ability of the person drawing blood to answer question (98.3% and 96.3% respectively). Moreover, the finding of this study revealed, statistical significant associations between the overall patients' satisfaction with waiting time to get blood drawing service, availability of ordered laboratory tests and waiting time to get laboratory result with (p ART monitoring laboratory services compared to those who underwent for more than 30 minutes. Overall, the satisfaction survey showed, most respondents were satisfied with ART monitoring laboratory services. However, factors such as improving accessibility and availability of latrines should be taken into consideration in order to improve the overall satisfaction.

    Background Despite advances in clinical chemistry testing, poor blood sample quality continues to impact laboratory operations and the quality of results. While previous studies have identified the preanalytical causes of lower sample quality, few studies have examined the economic impact of poor sample quality on the laboratory. Specifically, the costs associated with workarounds related to fibrin and gel contaminants remain largely unexplored. Methods A quantitative survey of clinical chemistry laboratory stakeholders across 10 international regions, including countries in North America, Europe and Oceania, was conducted to examine current blood sample testing practices, sample quality issues and practices to remediate poor sample quality. Survey data were used to estimate costs incurred by laboratories to mitigate sample quality issues. Results Responses from 164 participants were included in the analysis, which was focused on three specific issues: fibrin strands, fibrin masses and gel globules. Fibrin strands were the most commonly reported issue, with an overall incidence rate of ∼3%. Further, 65% of respondents indicated that these issues contribute to analyzer probe clogging, and the majority of laboratories had visual inspection and manual remediation practices in place to address fibrin- and gel-related quality problems (55% and 70%, respectively). Probe maintenance/replacement, visual inspection and manual remediation were estimated to carry significant costs for the laboratories surveyed. Annual cost associated with lower sample quality and remediation related to fibrin and/or gel globules for an average US laboratory was estimated to be $100,247. Conclusions Measures to improve blood sample quality present an important step towards improved laboratory operations.

    This cross-sectional study aimed to evaluate the conduct of nursing professionals who had been victims of accidents with biological material in a teaching hospital in the interior of the state of São Paulo, Brazil, regarding their care and specialized clinical follow-up. The study population consisted of 1,215 nursing professionals, who were interviewed individually between 2010 and 2011. Of the 1,215 nursing professionals interviewed, 636 (52.3%) reported having experienced accidents with biological material; of this population, 182 (28.6%) didn't sought specialized care. The most frequent reason reported for not seeking care was believing that it was a low-risk accident. The reasons professionals do not seek care and do not complete treatment and the clinical follow-up can contribute to strategies to increase professionals' adherence to prophylaxis measures after occupational exposure to biological material.

    To examine the basis of multidisciplinary teamwork. In real-world healthcare settings, clinicians often cluster in profession-based tribal silos, form hierarchies and exhibit stereotypical behaviours. It is not clear whether these social structures are more a product of inherent characteristics of the individuals or groups comprising the professions, or attributable to a greater extent to workplace factors. Controlled laboratory environment with well-appointed, quiet rooms and video and audio equipment. Clinical professionals (n=133) divided into 35 groups of doctors, nurses and allied health professions, or mixed professions. Participants engaged in one of three team tasks, and their performance was video-recorded and assessed. Primary: teamwork performance. Secondary, pre-experimental: a bank of personality questionnaires designed to assess participants' individual differences. Postexperimental: the 16-item Mayo High Performance Teamwork Scale (MHPTS) to measure teamwork skills; this was self-assessed by participants and also by external raters. In addition, external, arm's length blinded observations of the videotapes were conducted. At baseline, there were few significant differences between the professions in collective orientation, most of the personality factors, Machiavellianism and conservatism. Teams generally functioned well, with effective relationships, and exhibited little by way of discernible tribal or hierarchical behaviours, and no obvious differences between groups (F (3, 31)=0.94, p=0.43). Once clinicians are taken out of the workplace and put in controlled settings, tribalism, hierarchical and stereotype behaviours largely dissolve. It is unwise therefore to attribute these factors to fundamental sociological or psychological differences between individuals in the professions, or aggregated group differences. Workplace cultures are more likely to be influential in shaping such behaviours. The results underscore the importance of culture and

    Among National Institutes of Health HIV Research Networks conducting multicenter trials, samples from protocols that span several years are analyzed at multiple clinical pharmacology laboratories (CPLs) for multiple antiretrovirals. Drug assay data are, in turn, entered into study-specific data sets that are used for pharmacokinetic analyses, merged to conduct cross-protocol pharmacokinetic analysis, and integrated with pharmacogenomics research to investigate pharmacokinetic-pharmacogenetic associations. The CPLs participate in a semiannual proficiency testing (PT) program implemented by the Clinical Pharmacology Quality Assurance program. Using results from multiple PT rounds, longitudinal analyses of recovery are reflective of accuracy and precision within/across laboratories. The objectives of this longitudinal analysis of PT across multiple CPLs were to develop and test statistical models that longitudinally: (1) assess the precision and accuracy of concentrations reported by individual CPLs and (2) determine factors associated with round-specific and long-term assay accuracy, precision, and bias using a new regression model. A measure of absolute recovery is explored as a simultaneous measure of accuracy and precision. Overall, the analysis outcomes assured 97% accuracy (±20% of the final target concentration of all (21) drug concentration results reported for clinical trial samples by multiple CPLs). Using the Clinical Laboratory Improvement Act acceptance of meeting criteria for ≥2/3 consecutive rounds, all 10 laboratories that participated in 3 or more rounds per analyte maintained Clinical Laboratory Improvement Act proficiency. Significant associations were present between magnitude of error and CPL (Kruskal-Wallis P Kruskal-Wallis P < 0.001).

    To identify the relevant barriers and enablers perceived by primary care professionals in implementing the recommendations of clinical practice guidelines (CPG). Two focus groups were conducted with primary care physicians and nurses in Catalonia (Spain) between October and December 2012. Thirty-nine health professionals were selected based on their knowledge and daily use of CPG. Finally, eight general practitioners and eight nurses were included in the discussion groups. Participants were asked to share their views and beliefs on the accessibility of CPG, their knowledge and use of these documents, the content and format of CPG, dissemination strategy, training, professional-patient relationship, and the use of CPG by the management structure. We recorded and transcribed the content verbatim and analysed the data using qualitative analysis techniques. Physicians believed that, overall, CPG were of little practical use and frequently referred to them as a largely bureaucratic management control instrument that threatened their professional autonomy. In contrast, nurses believed that CPG were rather helpful tools in their day-to-day practice, although they would like them to be more sensitive to the current role of nurses. Both groups believed that CPG did not provide a response to most of the decisions they faced in the primary care setting. Compliance with CPG recommendations would be improved if these documents were brief, non-compulsory, not cost-containment oriented, more based on nursing care models, sensitive to the specific needs of primary care patients, and integrated into the computer workstation.

    Strengthening national health laboratory systems in resource-poor countries is critical to meeting the United Nations Millennium Development Goals. Despite strong commitment from the international community to fight major infectious diseases, weak laboratory infrastructure remains a huge rate-limiting step. Some major challenges facing laboratory systems in resource-poor settings include dilapidated infrastructure; lack of human capacity, laboratory policies, and strategic plans; and limited synergies between clinical and research laboratories. Together, these factors compromise the quality of test results and impact patient management. With increased funding, the target of laboratory strengthening efforts in resource-poor countries should be the integrating of laboratory services across major diseases to leverage resources with respect to physical infrastructure; types of assays; supply chain management of reagents and equipment; and maintenance of equipment.

    To assess the effects of a communication skills program on professional practitioners' performance and self-confidence in clinical interviewing. Twenty-five health professionals took 3 months of basic communication skills followed by 3 months of advanced communication skills. An additional quarter dealt with self-awareness and communication in special situations. Participants' performances were evaluated in clinical interviews with standardized patients before, during and after the program by external observers and standardized patients, using standardized instruments. Participants assessed their own confidence in their communication skills before and after the program. Data were analysed using GLM repeated-measures procedures in SPSS. Basic communication skills and self-confidence improved throughout the 6 months; competencies declined but self-confidence continued to increase 4 months later. Compared with taking no course, differences were statistically significant after the 6 months (external observers only) and 4 months later (external observers and participants). The program effectively improved communication skills, although significantly only when assessed by external observers. Four months later, effects were significant in communication skills (external observers), despite the decline and in self-confidence. While periodical enrollment in programs for the practice of communication skills may help maintain performance, more knowledge on communication and self-awareness may enhance self-confidence.

The need for overall efficiency in providing results is now given the same importance as accuracy. This means that laboratories must be able to produce quality results in less time with the capacity to interpret the results clinically. To improve the clinical impact of microbiology results, the new challenge facing the microbiologist has become one of process management instead of pure analysis. A proper project management process designed to improve workflow, reduce analytical time, and provide the same high quality results without losing valuable time treating the patient, has become essential. Our objective was to study the impact of introducing automation and computerization into the microbiology laboratory, and the reorganization of the laboratory workflow, i.e. scheduling personnel to work shifts covering both the entire day and the entire week. In our laboratory, the introduction of automation and computerization, as well as the reorganization of personnel, thus the workflow itself, has resulted in an improvement in response time and greater efficiency in diagnostic procedures.

    Organizing work flow is a major task of laboratory management. Recently, clinical laboratories have started to adopt methodologies such as Lean Six Sigma and some successful implementations have been reported. This study used Lean Six Sigma to simplify the laboratory work process and decrease the turnaround time by eliminating non-value-adding steps. The five-stage Six Sigma system known as define, measure, analyze, improve, and control (DMAIC) is used to identify and solve problems. The laboratory turnaround time for individual tests, total delay time in the sample reception area, and percentage of steps involving risks of medical errors and biological hazards in the overall process are measured. The pre-analytical process in the reception area was improved by eliminating 3 h and 22.5 min of non-value-adding work. Turnaround time also improved for stat samples from 68 to 59 min after applying Lean. Steps prone to medical errors and posing potential biological hazards to receptionists were reduced from 30% to 3%. Successful implementation of Lean Six Sigma significantly improved all of the selected performance metrics. This quality-improvement methodology has the potential to significantly improve clinical laboratories. © 2017 Wiley Periodicals, Inc.

    management challenges of clinical laboratories are more complicated for educational hospital clinical laboratories. Managers can use tools of business intelligence (BI), such as information dashboards that provide the possibility of intelligent decision-making and problem solving about increasing income, reducing spending, utilization management and even improving quality. Critical phase of dashboard design is setting indicators and modeling causal relations between them. The paper describes the process of creating a map for laboratory dashboard. the study is one part of an action research that begins from 2012 by innovation initiative for implementing laboratory intelligent dashboard. Laboratories management problems were determined in educational hospitals by the brainstorming sessions. Then, with regard to the problems key performance indicators (KPIs) specified. the map of indicators designed in form of three layered. They have a causal relationship so that issues measured in the subsequent layers affect issues measured in the prime layers. the proposed indicator map can be the base of performance monitoring. However, these indicators can be modified to improve during iterations of dashboard designing process.

    The organization of public clinical laboratories is experiencing changes without, however, an organizational assessment of its effectiveness. The study aimed to determine a parameter of effectiveness for public clinical laboratories of Belo Horizonte, Minas Gerais State, and set cut-off points for the sections of these laboratories. In order to do so, the total production and number of hours worked during a period of 7 months in the year 2008 were consolidated. Due to the entrance of the workers in the mode of production in the laboratories network, it could be observed a variability regarding the performance of these workers. The effectiveness parameter of the network was established in 29.90 tests per hour. As a consequence of this first analysis, the cut-off points are: 15.50 for the hematology section; 67.29 for chemistry; 6.45 for parasitology; 11.35 for urinalysis; 4.94 for microbiology and 19.03 for immunology. From these results, it was concluded that the working process in laboratories can generate a decrease in effectiveness.

    We conducted a questionnaire survey regarding the current activities for protecting patients' privacy and the security of information systems (IS) related to the clinical laboratory departments of university hospitals, certified training facilities for clinical laboratories, and general hospitals in Yamaguchi Prefecture. The response rate was 47% from 215 medical institutions, including three commercial clinical laboratory centers. The results showed that there were some differences in management activities among facilities with respect to continuing education, the documentation or regulation of operational management for paper records, electronic information, remaining samples, genetic testing, and laboratory information for secondary use. They were suggested to be caused by differences in functions between university and general hospitals, differences in the scale of hospitals, or whether or not hospitals have received accreditation or ISO 15189. Regarding the IS, although the majority of facilities had sufficiently employed the access control to IS, there was some room for improvement in the management of special cases such as VIPs and patients with HIV infection. Furthermore, there were issues regarding the login method for computers shared by multiple staff, the showing of the names of personnel in charge of reports, and the risks associated with direct connections to systems and the Internet and the use of portable media such as USB memory sticks. These results indicated that further efforts are necessary for each facility to continue self-assessment and make improvements.

    To cope with the government's policies to reduce medical costs, Taiwan's healthcare service providers are striving to survive by pursuing profit maximization through cost control. This article aimed to present the results of cost evaluation using activity-based costing performed in the laboratory in order to throw light on the differences between costs and the payment system of National Health Insurance (NHI). This study analyzed the data of costs and income of the clinical laboratory. Direct costs belong to their respective sections of the department. The department's shared costs, including public expenses and administrative assigned costs, were allocated to the department's respective sections. A simple regression equation was created to predict profit and loss, and evaluate the department's break-even point, fixed cost, and contribution margin ratio. In clinical chemistry and seroimmunology sections, the cost per test was lower than the NHI payment and their major laboratory tests had revenues with the profitability ratio of 8.7%, while the other sections had a higher cost per test than the NHI payment and their major tests were in deficit. The study found a simple linear regression model as follows: "Balance=-84,995+0.543×income (R2=0.544)". In order to avoid deficit, laboratories are suggested to increase test volumes, enhance laboratory test specialization, and become marginal scale. A hospital could integrate with regional medical institutions through alliances or OEM methods to increase volumes to reach marginal scale and reduce laboratory costs, enhancing the level and quality of laboratory medicine.

    Emergency nurses play an important role in the care of critically ill and injured patients, and their competency to perform clinical skills is vital to safe and effective patient care. The aim of this study was to evaluate the frequency of clinical skills performed and perceived competency levels among Iranian emergency nurses. In addition, attitudes toward expanding the professional roles of Iranian emergency nurses were also assessed. In this descriptive correlational study, 319 emergency nurses from 30 hospitals in northwest Iran participated. Data were collected using a self-report questionnaire. Descriptive statistics and Pearson's correlation coefficient were used to present the findings. Overall competency of the emergency nurses was 73.31 ± 14.2, indicating a good level of perceived competence. The clinical skills most frequently performed were in the domains of organizational and workload competencies (3.43 ± 0.76), diagnostic function (3.25 ± 0.82), and the helping role (3.17 ± 0.83). A higher level of perceived competence was found for skills within these domains. Less frequently, participants performed skills within the domains of effective management of rapidly changing situations (2.70 ± 0.94) and administering and monitoring therapeutic interventions (2.60 ± 0.97); a lower perceived level of competence was noted for these clinical skills. There was a significant correlation between frequency of performing clinical skills and perceived competency level (r = 0.651, P skills. This has implications for nurse managers and educators who may consider offering more frequent experiential and educational opportunities to emergency nurses. Expansion of nurses' roles could also result in increased experience in clinical skills and higher levels of competency. Research is needed to investigate nurses' clinical competence using direct and observed measures. Copyright © 2017 Emergency Nurses Association. Published by Elsevier Inc. All rights reserved.

    Timely delivery of correct results has long been considered as the goal of quality management in clinical laboratory. With increasing workload as well as complexities of laboratory testing and patient care, the traditional technical adopted like internal quality control (IQC) and external quality assessment (EQA) may not enough to cope with quality management problems for clinical laboratories. We applied failure mode and effects analysis (FMEA), a proactive tool, to reduce errors associated with the process beginning with sample collection and ending with a test report in a clinical chemistry laboratory. Our main objection was to investigate the feasibility of FMEA in a real-world situation, namely the working environment of hospital. A team of 8 people (3 laboratory workers, 2 couriers, 2 nurses, and 1 physician) from different departments who were involved in the testing process were recruited and trained. Their main responsibility was to analyze and score all possible clinical chemistry laboratory failures based on three aspects: the severity of the outcome (S), the likeliness of occurrence (O), and the probability of being detected (D). These three parameters were multiplied to calculate risk priority numbers (RPNs), which were used to prioritize remedial measures. Failure modes with RPN≥200 were deemed as high risk, meaning that they needed immediate corrective action. After modifications that were put, we compared the resulting RPN with the previous one. A total of 33 failure modes were identified. Many of the failure modes, including the one with the highest RPN (specimen hemolysis) appeared in the pre-analytic phase, whereas no high-risk failure modes (RPN≥200) were found during the analytic phase. High-priority risks were "sample hemolysis" (RPN, 336), "sample delivery delay" (RPN, 225), "sample volume error" (RPN, 210), "failure to release results in a timely manner" (RPN, 210), and "failure to identify or report critical results" (RPN, 200).

    To determine whether clinical supervision (CS) of health professionals improves patient safety. Databases MEDLINE, PsychINFO, CINAHL, EMBASE and AMED were searched from earliest date available. Additional studies were identified by searching of reference lists and citation tracking. Two reviewers independently applied inclusion and exclusion criteria. Thirty-two studies across three health professions [medicine (n = 29), nursing (n = 2) and paramedicine (n = 1)] were selected. The quality of each study was rated using the Medical Education Research Study Quality Instrument. Risk ratios (RR) were calculated for patient safety outcomes of mortality, complications, adverse events, reoperation following initial surgery, conversion to more invasive surgery and readmission to hospital. Results of meta-analyses provided low-quality evidence that supervision of medical professionals reduced the risk of mortality (RR 0.76, 95% CI 0.60-0.95, I(2) = 76%) and supervision of medical professionals and paramedics reduced the risk of complications (RR 0.69, 95% CI 0.53-0.89, I(2) = 76%). Due to a high level of statistical heterogeneity, sub-group analyses were performed. Sub-group analyses provided moderate-quality evidence that direct supervision of surgery significantly reduced the risk of mortality (RR 0.68, 95% CI 0.50-0.93, I(2) = 33%) and direct supervision of medical professionals conducting non-surgical invasive procedures significantly reduced the risk of complications (RR 0.33, 95% CI 0.24-0.46, I(2) = 0%). CS was associated with safer surgery and other invasive procedures for medical practitioners. There was a lack of evidence about the relationship between CS and safer patient care for non-medical health professionals. © The Author 2016.

    Full Text Available Abstract Background The diagnosis of malaria can be difficult in non-endemic areas, such as the United States, and delays in diagnosis and errors in treatment occur too often. Methods A nationwide survey of laboratories in the United States and its nine dependent territories was conducted in 2010 to determine factors that may contribute to shortcomings in the diagnosis of malaria. This survey explored the availability of malaria diagnostic tests, techniques used, and reporting practices. Results The survey was completed by 201 participants. Ninety percent reported that their laboratories had at least one type of malaria diagnostic test available on-site. Nearly all of the respondents' laboratories performed thick and thin smears on-site; approximately 50% had access to molecular testing; and only 17% had access to rapid diagnostic tests on-site. Seventy-three percent reported fewer than five confirmed cases of malaria in their laboratory during the 12-month period preceding the survey. Twenty-eight percent stated that results of species identification took more than 24 hours to report. Only five of 149 respondents that performed testing 24 hours a day, 7 days a week complied with all of the Clinical and Laboratory Standards Institute (CLSI guidelines for analysis and reporting of results. Conclusion Although malaria diagnostic testing services were available to a majority of U.S. laboratories surveyed, very few were in complete compliance with all of the CLSI guidelines for analysis and reporting of results, and most respondents reported very few cases of malaria annually. Laboratories' difficulty in adhering to the rigorous CLSI guidelines and their personnel's lack of practice and proficiency may account for delays and errors in diagnosis. It is recommended that laboratories that infrequently process samples for malaria seek opportunities for practice and proficiency training annually and take advantage of available resources to assist in

  4. Taking a new biomarker into routine use – A perspective from the routine clinical biochemistry laboratory

    There is increasing pressure to provide cost-effective healthcare based on “best practice.” Consequently, new biomarkers are only likely to be introduced into routine clinical biochemistry departments if they are supported by a strong evidence base and if the results will improve patient management and outcome. This requires convincing evidence of the benefits of introducing the new test, ideally reflected in fewer hospital admissions, fewer additional investigations and/or fewer clinic visits. Carefully designed audit and cost-benefit studies in relevant patient groups must demonstrate that introducing the biomarker delivers an improved and more effective clinical pathway. From the laboratory perspective, pre-analytical requirements must be thoroughly investigated at an early stage. Good stability of the biomarker in relevant physiological matrices is essential to avoid the need for special processing. Absence of specific timing requirements for sampling and knowledge of the effect of medications that might be used to treat the patients in whom the biomarker will be measured is also highly desirable. Analytically, automation is essential in modern high-throughput clinical laboratories. Assays must therefore be robust, fulfilling standard requirements for linearity on dilution, precision and reproducibility, both within- and between-run. Provision of measurements by a limited number of specialized reference laboratories may be most appropriate, especially when a new biomarker is first introduced into routine practice. PMID:21137030

    Full Text Available A clinical and laboratory evaluation of 11 children and young adults with measleslike rash was done during the measles outbreak in the Greater São Paulo Metropolitan area at the end of 1996 and spread over the country during 1997. Measles was laboratory confirmed in 07 patients by specific IgM detection in acute serum specimens using an IgM-capture EIA, by specific IgG seroconversion in serum pairs, and by reverse transcription PCR and virus isolation in peripheral blood lymphocytes. Clinical presentations were not always classic; one of the 07 cases had received measles vaccine and corresponded to modified clinical case of measles. The 4 remaining cases were negative for measles and were diagnosed as exanthem subitum (2 cases, scarlet fever and Kawasaki disease. The present study reinforces the view that clinical features alone are not sufficient for establishing an accurate diagnosis in the post-vaccine era, and a surveillance system based on sensitive laboratory results is needed so that it can confirm IgM-negative measles cases.

    To identify areas where clinical nurse managers perceived that they would benefit from further training and to make recommendations for planning future programmes to meet their needs. The effectiveness of the clinical nurse manager has traditionally been associated with maintaining standards of care. Continuing professional development (CPD) is essential to ensure this important group feel adequately prepared to perform their role and has been recognized as an important factor in maintaining job satisfaction and reducing wasteful staff turnover. A review of the literature indicated that since the 1980s the CPD needs of clinical nurse managers have tended to be overlooked despite increasing complexity of the tasks expected of them. Thus it appeared that a fresh study to address these needs would be justified and should take into account sources of work-related stress and variables relating to job satisfaction. The study involved clinical nurse managers employed in all four acute hospital National Health Service (NHS) trusts where training needs were served by a major inner city educational consortium. Data collection proceeded in two stages. Initially interviews were undertaken with a random sample of 15 clinical nurse managers to provide in-depth, qualitative data. This information was used to develop a survey questionnaire distributed to the remaining 182 clinical nurse managers in each of the trusts. Data from the interviews indicated that clinical nurse managers appeared to feel clinically competent but generally experienced lack of confidence when dealing with a range of issues, in particular; human resources, managing budgets, deputizing for senior colleagues across the trust ('acting up') and using information technology in everyday practice. Response rate to the survey was good (65%). The results corroborated the interview findings, indicating a need for updating in the same wide range of topics. There were few differences in training needs across all four

    Full Text Available Background: Autoverification is a process of using computer-based rules to verify clinical laboratory test results without manual intervention. To date, there is little published data on the use of autoverification over the course of years in a clinical laboratory. We describe the evolution and application of autoverification in an academic medical center clinical chemistry core laboratory. Subjects and Methods: At the institution of the study, autoverification developed from rudimentary rules in the laboratory information system (LIS to extensive and sophisticated rules mostly in middleware software. Rules incorporated decisions based on instrument error flags, interference indices, analytical measurement ranges (AMRs, delta checks, dilution protocols, results suggestive of compromised or contaminated specimens, and ′absurd′ (physiologically improbable values. Results: The autoverification rate for tests performed in the core clinical chemistry laboratory has increased over the course of 13 years from 40% to the current overall rate of 99.5%. A high percentage of critical values now autoverify. The highest rates of autoverification occurred with the most frequently ordered tests such as the basic metabolic panel (sodium, potassium, chloride, carbon dioxide, creatinine, blood urea nitrogen, calcium, glucose; 99.6%, albumin (99.8%, and alanine aminotransferase (99.7%. The lowest rates of autoverification occurred with some therapeutic drug levels (gentamicin, lithium, and methotrexate and with serum free light chains (kappa/lambda, mostly due to need for offline dilution and manual filing of results. Rules also caught very rare occurrences such as plasma albumin exceeding total protein (usually indicative of an error such as short sample or bubble that evaded detection and marked discrepancy between total bilirubin and the spectrophotometric icteric index (usually due to interference of the bilirubin assay by immunoglobulin (Ig M monoclonal

    Understanding the human experience is no longer an outcome explored strictly by social and behavioral researchers. Increasingly, biomedical researchers are also including patient reported outcomes (PROs) in their clinical research studies not only due to calls for increased patient engagement in research but also healthcare. Collecting PROs in clinical research studies offers a lens into the patient's unique perspective providing important information to industry sponsors and the FDA. Approximately 30% of trials include PROs as primary or secondary endpoints and a quarter of FDA new drug, device and biologic applications include PRO data to support labeling claims. In this paper PRO, represents any information obtained directly from the patient or their proxy, without interpretation by another individual to ascertain their health, evaluate symptoms or conditions and extends the reference of PRO, as defined by the FDA, to include other sources such as patient diaries. Consumers and clinicians consistently report that PRO data are valued, and can aide when deciding between treatment options; therefore an integral part of clinical research. However, little guidance exists for clinical research professionals (CRPs) responsible for collecting PRO data on the best practices to ensure quality data collection so that an accurate assessment of the patient's view is collected. Therefore the purpose of this work was to develop and validate a checklist to guide quality collection of PRO data. The checklist synthesizes best practices from published literature and expert opinions addressing practical and methodological challenges CRPs often encounter when collecting PRO data in research settings.

    Infectious mononucleosis (IM) or Mononucleosis syndrome is caused by an acute infection of Epstein-Barr virus. In Latin American countries, there are little information pertaining to the clinical manifestations and complications of this disease. For this reason, the purpose of this work was to describe the clinical and laboratory characteristics of infection by Epstein-Barr virus in Mexican children with infectious mononucleosis. A descriptive study was carried out by reviewing the clinical files of patients less than 18 years old with clinical and serological diagnosis of IM by Epstein-Barr virus from November, 1970 to July, 2011 in a third level pediatric hospital in Mexico City. One hundred and sixty three cases of IM were found. The most frequent clinical signs were lymphadenopathy (89.5%), fever (79.7%), general body pain (69.3%), pharyngitis (55.2%), hepatomegaly (47.2%). The laboratory findings were lymphocytosis (41.7%), atypic lymphocytes (24.5%), and increased transaminases (30.9%), there were no rupture of the spleen and no deaths among the 163 cases. Our results revealed that IM appeared in earlier ages compared with that reported in industrialized countries, where adolescents are the most affected group. Also, the order and frequency of the clinical manifestations were different in our country than in industrialized ones.

    To draw on empirical evidence to illustrate the core role of nurse practitioners in Australia and New Zealand. Enacted legislation provides for mutual recognition of qualifications, including nursing, between New Zealand and Australia. As the nurse practitioner role is relatively new in both countries, there is no consistency in role expectation and hence mutual recognition has not yet been applied to nurse practitioners. A study jointly commissioned by both countries' Regulatory Boards developed information on the core role of the nurse practitioner, to develop shared competency and educational standards. Reporting on this study's process and outcomes provides insights that are relevant both locally and internationally. This interpretive study used multiple data sources, including published and grey literature, policy documents, nurse practitioner program curricula and interviews with 15 nurse practitioners from the two countries. Data were analysed according to the appropriate standard for each data type and included both deductive and inductive methods. The data were aggregated thematically according to patterns within and across the interview and material data. The core role of the nurse practitioner was identified as having three components: dynamic practice, professional efficacy and clinical leadership. Nurse practitioner practice is dynamic and involves the application of high level clinical knowledge and skills in a wide range of contexts. The nurse practitioner demonstrates professional efficacy, enhanced by an extended range of autonomy that includes legislated privileges. The nurse practitioner is a clinical leader with a readiness and an obligation to advocate for their client base and their profession at the systems level of health care. A clearly articulated and research informed description of the core role of the nurse practitioner provides the basis for development of educational and practice competency standards. These research findings provide

    The aim of this study is to determine inter-laboratory variability on embryo assessment using time-lapse platform and conventional morphological assessment. This study compares the data obtained from a pilot study of external quality control (EQC) of time lapse, performed in 2014, with the classical EQC of the Spanish Society for the Study of Reproductive Biology (ASEBIR) performed in 2013 and 2014. In total, 24 laboratories (8 using EmbryoScope™, 15 using Primo Vision™ and one with both platforms) took part in the pilot study. The clinics that used EmbryoScope™ analysed 31 embryos and those using Primo Vision™ analysed 35. The classical EQC was implemented by 39 clinics, based on an analysis of 25 embryos per year. Both groups were required to evaluate various qualitative morphological variables (cell fragmentation, the presence of vacuoles, blastomere asymmetry and multinucleation), to classify the embryos in accordance with ASEBIR criteria and to stipulate the clinical decision taken. In the EQC time-lapse pilot study, the groups were asked to determine, as well as the above characteristics, the embryo development times, the number, opposition and size of pronuclei, the direct division of 1 into 3 cells and/or of 3 into 5 cells and false divisions. The degree of agreement was determined by calculating the intra-class correlation coefficients and the coefficient of variation for the quantitative variables and the Gwet index for the qualitative variables. For both EmbryoScope™ and Primo Vision™, two periods of greater inter-laboratory variability were observed in the times of embryo development events. One peak of variability was recorded among the laboratories addressing the first embryo events (extrusion of the second polar body and the appearance of pronuclei); the second peak took place between the times corresponding to the 8-cell and morula stages. In most of the qualitative variables analysed regarding embryo development, there was almost

    The interpretation and the accuracy of the microbiological results still depend to a great extent on the quality of the samples and their processing within the Microbiology laboratory. The type of specimen, the appropriate time to obtain the sample, the way of sampling, the storage and transport are critical points in the diagnostic process. The availability of new laboratory techniques for unusual pathogens, makes necessary the review and update of all the steps involved in the processing of the samples. Nowadays, the laboratory automation and the availability of rapid techniques allow the precision and turn-around time necessary to help the clinicians in the decision making. In order to be efficient, it is very important to obtain clinical information to use the best diagnostic tools.

    BACKGROUND Since 1989, several investigators have reported unusual cases of severe opportunistic infections associated with CD4 lymphocytopenia in the absence of human immunodeficiency virus infection. The cause of this condition is unknown. The Centres for Disease Control and Prevention (CDC) defines Idiopathic CD4 T Lymphocytopenia (ICL) as a clinical condition in which patients with depressed numbers of circulating CD4+ T-cell lymphocytes (

    Although laboratory medicine practise varies across the European Union's (EU) member states, the extent of overlap in scope is such that a common syllabus describing the education and training associated with high-quality, specialist practise can be identified. In turn, such a syllabus can help define the common set of skills, knowledge and competence in a Common Training Framework (CTF) for non-medical Specialists in Laboratory Medicine under EU Directive 2013/55/EU (The recognition of Professional Qualifications). In meeting the requirements of the directive's CTF patient safety is particularly enhanced when specialists seek to capitalise on opportunities for free professional migration across EU borders. In updating the fourth syllabus, the fifth expands on individual discipline requirements, new analytical techniques and use of statistics. An outline structure for a training programme is proposed together with expected responsibilities of trainees and trainers; reference is provided to a trainee's log book. In updating the syllabus, it continues to support national programmes and the aims of EU Directive 2013/55/EU in providing safeguards to professional mobility across European borders at a time when the demand for highly qualified professionals is increasing in the face of a disparity in their distribution across Europe. In support of achieving a CTF, the syllabus represents EFLM's position statement for the education and training that underpins the framework.

    Email is a popular and commonly-used method of communication, but its use in health care is not routine. Where email communication has been demonstrated in health care this has included its use for communication between patients/caregivers and healthcare professionals for clinical purposes, but the effects of using email in this way is not known.This review addresses the use of email for two-way clinical communication between patients/caregivers and healthcare professionals. To assess the effects of healthcare professionals and patients using email to communicate with each other, on patient outcomes, health service performance, service efficiency and acceptability. We searched: the Cochrane Consumers and Communication Review Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1 2010), MEDLINE (OvidSP) (1950 to January 2010), EMBASE (OvidSP) (1980 to January 2010), PsycINFO (OvidSP) (1967 to January 2010), CINAHL (EbscoHOST) (1982 to February 2010) and ERIC (CSA) (1965 to January 2010). We searched grey literature: theses/dissertation repositories, trials registers and Google Scholar (searched July 2010). We used additional search methods: examining reference lists, contacting authors. Randomised controlled trials, quasi-randomised trials, controlled before and after studies and interrupted time series studies examining interventions using email to allow patients to communicate clinical concerns to a healthcare professional and receive a reply, and taking the form of 1) unsecured email 2) secure email or 3) web messaging. All healthcare professionals, patients and caregivers in all settings were considered. Two authors independently assessed the risk of bias of included studies and extracted data. We contacted study authors for additional information. We assessed risk of bias according to the Cochrane Handbook for Systematic Reviews of Interventions. For continuous measures, we report effect sizes as mean

    As with many studies carried out in European countries, a quality assurance program has been established by the National Center for Clinical Laboratories in China (NCCL). The results showed that the external quality assessment significantly improves laboratory performance for quantitative evaluation of hepatitis C virus (HCV) RNA. Serum panels were delivered twice annually to the clinical laboratories which performed HCV RNA detection in China. Each panel made up of 5 coded samples. All laboratories were requested to carry out the detection within the required time period and report on testing results which contained qualitative and/or quantitative test findings, reagents used and relevant information about apparatus. All the positive samples were calibrated against the first International Standard for HCV RNA in a collaborative study and the range of comparison target value (TG) designated as +/- 0.5 log. The numbers of laboratories reporting on qualitative testing results for the first and second time external quality assessment were 168 and 167 in the year of 2003 and increased to 209 and 233 in 2007; the numbers of laboratories reporting on quantitative testing results were 134 and 147 in 2003 and rose to 340 and 339 in 2007. Deviation between the mean value for quantitative results at home in 2003 and the target value was above 0.5 log, which was comparatively high. By 2007, the target value was close to the national average except for the low concentrated specimens (10(3) IU/ml). The percentage of results within the range of GM +/- 0.5 log(10) varied from 8.2% to 93.5%. Some laboratories had some difficulties in the exact quantification of the lowest (3.00 log IU/ml) as well as of the highest viral levels (6.37 log IU/ml) values, very near to the limits of the dynamic range of the assays. The comparison of these results with the previous study confirms that a regular participation in external quality assessment (EQA) assures the achievement of a high

    MODULAR ANALYTICS (Roche Diagnostics) (MODULAR ANALYTICS, Elecsys and Cobas Integra are trademarks of a member of the Roche Group) represents a new approach to automation for the clinical chemistry laboratory. It consists of a control unit, a core unit with a bidirectional multitrack rack transportation system, and three distinct kinds of analytical modules: an ISE module, a P800 module (44 photometric tests, throughput of up to 800 tests/h), and a D2400 module (16 photometric tests, throughput up to 2400 tests/h). MODULAR ANALYTICS allows customised configurations for various laboratory workloads. The performance and practicability of MODULAR ANALYTICS were evaluated in an international multicentre study at 16 sites. Studies included precision, accuracy, analytical range, carry-over, and workflow assessment. More than 700 000 results were obtained during the course of the study. Median between-day CVs were typically less than 3% for clinical chemistries and less than 6% for homogeneous immunoassays. Median recoveries for nearly all standardised reference materials were within 5% of assigned values. Method comparisons versus current existing routine instrumentation were clinically acceptable in all cases. During the workflow studies, the work from three to four single workstations was transferred to MODULAR ANALYTICS, which offered over 100 possible methods, with reduction in sample splitting, handling errors, and turnaround time. Typical sample processing time on MODULAR ANALYTICS was less than 30 minutes, an improvement from the current laboratory systems. By combining multiple analytic units in flexible ways, MODULAR ANALYTICS met diverse laboratory needs and offered improvement in workflow over current laboratory situations. It increased overall efficiency while maintaining (or improving) quality.

    2012-01-01

    The aim of this study was to prepare, pilot and validate a questionnaire to evaluate patient safety in the specific context of clinical laboratories. A specific questionnaire on patient safety in the laboratory, with 62 items grouped into six areas, was developed, taking into consideration the diverse human and laboratory contextual factors which may contribute to producing errors. A pilot study of 30 interviews was carried out, including validity and reliability analyses using principal components factor analysis and Cronbach's alpha. Subsequently, 240 questionnaires were sent to 21 hospitals, followed by a test-retest of 41 questionnaires with the definitive version. The sample analyzed was composed of 225 questionnaires (an overall response rate of 80%). Of the 62 items initially assessed, 17 were eliminated due to non-compliance with the criteria established before the principal components factor analysis was performed. For the 45 remaining items, 12 components were identified, with an cumulative variance of 69.5%. In seven of the 10 components with two or more items, Cronbach's alpha was higher than 0.7. The questionnaire items assessed in the test-retest were found to be stable. We present the first questionnaire with sufficiently proven validity and reliability for evaluating patient safety in the specific context of clinical laboratories. This questionnaire provides a useful instrument to perform a subsequent macrostudy of hospital clinical laboratories in Spain. The questionnaire can also be used to monitor and promote commitment to patient safety within the search for continuous quality improvement. Copyright © 2011 SESPAS. Published by Elsevier Espana.

    2016-02-02

    This study aimed to analyse and redesign the outpatient clinic in a paediatric department. The study was a joint collaboration with the doctors of the department (paediatric residents and specialists) using the Change Laboratory intervention method as a means to model and implement change in the outpatient clinic. This study was motivated by a perceived failure to integrate the activities of the outpatient clinic, patient care and training of residents. The ultimate goal of the intervention was to create improved care for patients through resident learning and development. We combined the Change Laboratory intervention with an already established innovative process for residents, 3-h meetings. The Change Laboratory intervention method consists of a well-defined theory (Cultural-historical activity theory) and concrete actions where participants construct a new theoretical model of the activity, which in this case was paediatric doctors' workplace learning modelled in order to improve medical social practice. The notion of expansive learning was used during the intervention in conjunction with thematic analysis of data in order to fuel the process of analysis and intervention. The activity system of the outpatient clinic can meaningfully be analysed in terms of the objects of patient care and training residents. The Change Laboratory sessions resulted in a joint action plan for the outpatient clinic structured around three themes: (1) Before: Preparation, expectations, and introduction; (2) During: Structural context and resources; (3) After: Follow-up and feedback. The participants found the Change Laboratory method to be a successful way of sharing reflections on how to optimise the organisation of work and training with patient care in mind. The Change Laboratory approach outlined in this study succeeded to change practices and to help medical doctors redesigning their work. Participating doctors must be motivated to uncover inherent contradictions in their

    The AstraZeneca and Covance Laboratories Clinical Bioanalysis Alliance (CBioA) was launched in 2011 after a period of global economic recession. In this challenging environment, AstraZeneca elected to move to a full and centralized outsourcing model that could optimize the number of people supporting bioanalytical work and reduce the analytical cost. This paper describes the key aspects of CBioA, the innovative operational model implemented, and our ways of ensuring this was much more than simply a cost reduction exercise. As we have recently passed the first 5-year cycle, this paper also summarizes some of the concluding benefits, wins and lessons learned, and how we now plan to extend and develop the relationship even further moving into a new clinical laboratory partnership.

    Real-time PCR has revolutionized the way clinical microbiology laboratories diagnose many human microbial infections. This testing method combines PCR chemistry with fluorescent probe detection of amplified product in the same reaction vessel. In general, both PCR and amplified product detection are completed in an hour or less, which is considerably faster than conventional PCR detection methods. Real-time PCR assays provide sensitivity and specificity equivalent to that of conventional PCR combined with Southern blot analysis, and since amplification and detection steps are performed in the same closed vessel, the risk of releasing amplified nucleic acids into the environment is negligible. The combination of excellent sensitivity and specificity, low contamination risk, and speed has made real-time PCR technology an appealing alternative to culture- or immunoassay-based testing methods for diagnosing many infectious diseases. This review focuses on the application of real-time PCR in the clinical microbiology laboratory. PMID:16418529

    We aimed to determine clinical, laboratory and demographical characteristics of tularemia on admission to Emergency Department (ED). Medical data of 317 patients admitted to ED and subsequently hospitalized with suspected tularemia between January 1, 2011, and May 31, 2015, were collected. Patients were divided into 2 groups according to microagglutination test results, as tularemia (+) and tularemia (-). Of the 317 patients involved, 49 were found to be tularemia (+) and 268 were tularemia (-). Mean age of the tularemia (+) patients was found to be higher than that of tularemia (-) patients. When compared to tularemia (-) patients, a significant portion of patients in tularemia (+) patients were elderly, living in rural areas and had contact with rodents. When clinical and laboratory findings of the 2 groups were compared, any statistical significance could not be determined. Tularemia is a disease of elderly people living in rural areas. Contact with rodents also increases risk of tularemia in suspected patients. Copyright © 2015 Elsevier Inc. All rights reserved.

    Brucellosis is the most common zoonotic disease worldwide and remains an important human disease especially in developing countries. The aim of the present study was to evaluate clinical manifestations and laboratory findings of childhood brucellosis in Van province of Eastern Turkey. To our knowledge, this is the largest series of childhood brucellosis reported in the literature. In this retrospective study, 496 children with brucellosis were assessed for the clinical manifestations and laboratory findings from July 2009 through December 2013. The diagnosis of brucellosis was based on clinical findings and a standard tube agglutination test (titer ≥ 1:160). Data were analyzed using Minitab version 16. The study included 496 children (boys, 60.5%) with a mean age of 10.0 ± 3.95 years (range, 1-16 years). The most frequent clinical symptoms were arthralgia (46.2%), fever (32.1%), and abdominal pain (17.1%) and the most common clinical signs were peripheral arthritis (10.1%), splenomegaly (2.2%) and hepatomegaly (1.8%). The most contagious seasons were summer and autumn (63.3%). Elevated lactate dehydrogenase and C-reactive protein and erythrocyte sedimentation rate were reported in 63.1%, 58.7%, and 55.2% of the patients, respectively. Anemia (20.4%), thrombocytopenia (15.5%), and leukopenia (12.1%) were the most common hematologic findings. Brucellosis remains a serious public health problem in Turkey. The clinical and laboratory characteristics of childhood brucellosis have been described in order to assist clinicians in diagnosing and monitoring the disease. © 2015 Japan Pediatric Society.

    Asthma takes up a great importance in occupational diseases but remains underestimated as it is insufficiently diagnosed. We aimed to access the clinical and professional profile of the Tunisian asthmatic worker. It was a retrospective descriptive study in a professional pathology unit in a university hospital. All patients referred by their doctor for symptoms suggestive of occupational asthma, during a period from 2000 to 2008, were included. Forty-eight patients were selected from 172. The mean age was 40 years, with a male predominance (56 %). In 2/3 of the cases, it was the textile workers, food and chemical industry. The etiological agents incriminated were textile dust in 18.8 % of cases followed by isocyanates and flour. Typical episodes of wheezing dyspnea were present in 52 % and atopy in 54.2 % of workers. In 2 % of cases, symptoms disappeared and worsened in 18.8 %. The prognosis of OA depends on early end accurate diagnosis. The physician's role is to initiate the appropriate diagnostic approach, which must comply with the Tunisian conditions. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Since U.S. Congress' 2010 passing of the Affordable Care Act and the creation of numerous care coordination programs, Mount Sinai Hospital's Department of Social Work Services has experienced exponential growth. The Department is deeply committed to recruiting and developing the most talented social workers to best meet the needs of patients and family caregivers and to serve as integral, valued members of interdisciplinary care teams. Traditional learning methods are insufficient for a staff of hundreds, given the changes in health care and the complexity of the work. This necessitates the use of new training and education methods to maintain the quality of professional development. This article provides an overview of the Department's strategy and creation of a professional development learning platform to transform clinical social work practice. It reviews various education models that utilize an e-learning management system and case studies using standardized patients. These models demonstrate innovative learning approaches for both new and experienced social workers in health care. The platform's successes and challenges and recommendations for future development and sustainability are outlined.

    Laboratory reference ranges used for clinical care and clinical trials in various laboratories in Zimbabwe were derived from textbooks and research studies conducted more than ten years ago. Periodic verification of these ranges is essential to track changes over time. The purpose of this study was to establish hematology and chemistry laboratory reference ranges using more rigorous methods. A community-based cross-sectional study was carried out in Harare, Chitungwiza, and Mutoko. A multistage sampling technique was used. Samples were transported from the field for analysis at the ISO15189 certified University of Zimbabwe-University of California San Francisco Central Research Laboratory. Hematology and clinical chemistry reference ranges lower and upper reference limits were estimated at the 2.5th and 97.5th percentiles respectively. A total of 769 adults (54% males) aged 18 to 55 years were included in the analysis. Median age was 28 [IQR: 23-35] years. Males had significantly higher red cell counts, hemoglobin, hematocrit, and mean corpuscular hemoglobin compared to females. Females had higher white cell counts, platelets, absolute neutrophil counts, and absolute lymphocyte counts compared to males. There were no gender differences in eosinophils, monocytes, and absolute basophil count. Males had significantly higher levels of urea, sodium, potassium, calcium, creatinine, amylase, total protein, albumin and liver enzymes levels compared to females. Females had higher cholesterol and lipase compared with males. There are notable differences in the white cell counts, neutrophils, cholesterol, and creatinine kinase when compared with the currently used reference ranges. Data from this study provides new country specific reference ranges which should be immediately adopted for routine clinical care and accurate monitoring of adverse events in research studies.

    This study aimed to analyse laboratory values according to fever duration, and evaluate the relationship across these values during the acute phase of Kawasaki disease (KD) to aid in the early diagnosis for early-presenting KD and incomplete KD patients. Clinical and laboratory data of patients with KD (n=615) were evaluated according to duration of fever at presentation, and were compared between patients with and without coronary artery lesions (CALs). For evaluation of the relationships across laboratory indices, patients with a fever duration of 5 days or 6 days were used (n=204). The mean fever duration was 6.6±2.3 days, and the proportions of patients with CALs was 19.3% (n=114). C-reactive proteins (CRPs) and neutrophil differential values were highest and hemoglobin, albumin, and lymphocyte differential values were lowest in the 6-day group. Patients with CALs had longer total fever duration, higher CRP and neutrophil differential values and lower hemoglobin and albumin values compared to patients without CALs. CRP, albumin, neutrophil differential, and hemoglobin values at the peak inflammation stage of KD showed positive or negative correlations each other. The severity of systemic inflammation in KD was reflected in the laboratory values including CRP, neutrophil differential, albumin, and hemoglobin. Observing changes in these laboratory parameters by repeated examinations prior to the peak of inflammation in acute KD may aid in diagnosis of early-presenting KD patients.

    This survey was initiated to estimate the current status of turnaround time (TAT) monitoring of clinical biochemistry in China, provide baseline data for establishment of quality specifications and analyze the impact factors of TAT. 738 laboratories were included. Questionnaires involved general information and data of related indicators of TAT during 1 week were provided to participating laboratories. Nine quality indicators were covered, which were medians, 90th and outlier rates of pre-examination, examination, and post-examination TAT. The 25th percentile, median, and 75th percentile of TATs were calculated as optimum, desirable, and minimum quality specifications. Percentages and sigma values were used to describe the outlier rates. Mann-Whitney and Kruskal-Wallis tests were used to identify the potential impacts of TAT. Response rate of this survey was 46.44%. More than 50% of the laboratories indicated they had set up target TATs in three time intervals and monitored TATs generally. The post-examination TAT of most laboratories was 0min, while the pre-examination and examination TAT varied. Sigma values of outlier rates for 45%~60% of laboratories were above 4, while 15%~20% of labs whose sigma values were below 3. Group comparisons suggested nurse or mechanical pipeline transportation, link laboratory information system with hospital information system, and using computer reporting instead of printing report were related to shorter TATs. Despite of the remarkable progresses of TATs in China, there was also room to improve. Laboratories should strengthen the construction of information systems, identify reasons for TAT delay to improve the service quality continuously. © 2017 Wiley Periodicals, Inc.

    Objective: To explore the typical sonographic features of gray-scale and Power Doppler of acute and chronic gouty arthritis in conjunction with radiographic, clinical, and laboratory findings. Materials and methods: All hand, finger, and toe joints of 19 patients with acute and chronic gout were examined with gray-scale and Power Doppler sonography. The number and size of bone changes detected with sonography was compared to radiographic findings. Vascularization of the synovial tissue was scored on Power Doppler (grades 0-3), and was compared with clinical appearance, including swelling, tenderness, and redness (grades 0-3). Results: In acute gout, mild to moderate echogenic periarticular nodules with sonotransmission and hypervascularization of the edematous surrounding soft tissue were found. In chronic gout, tophaceous nodules completely blocked transmission of US wave, leading to strong reflexion and dorsal shadowing in a minority of cases. No significant difference in the detection of large bone changes (>2 mm) was found between sonography and radiography. However, gray-scale sonography was significantly more sensitive in the detection of small bone changes (p < 0.001). Power Doppler scores were statistically significantly higher than clinical examination scores (p < 0.001). Discussion: Sonography is superior to radiographs in evaluating small bone changes. The inflammatory process in joints can be better detected with Power Doppler sonography than with clinical examination. Typical sonographic appearance of acute and in particular of chronic gout might provide clues on gouty arthritis that adds to the information available from conventional radiography, clinical, and laboratory findings

    GraphROC for Windows is a program for clinical test evaluation. It was designed for the handling of large datasets obtained from clinical laboratory databases. In the user interface, graphical and numerical presentations are combined. For simplicity, numerical data is not shown unless requested. Relevant numbers can be "picked up" from the graph by simple mouse operations. Reference distributions can be displayed by using automatically optimized bin widths. Any percentile of the distribution with corresponding confidence limits can be chosen for display. In sensitivity-specificity analysis, both illness- and health-related distributions are shown in the same graph. The following data for any cutoff limit can be shown in a separate click window: clinical sensitivity and specificity with corresponding confidence limits, positive and negative likelihood ratios, positive and negative predictive values and efficiency. Predictive values and clinical efficiency of the cutoff limit can be updated for any prior probability of disease. Receiver Operating Characteristics (ROC) curves can be generated and combined into the same graph for comparison of several different tests. The area under the curve with corresponding confidence interval is calculated for each ROC curve. Numerical results of analyses and graphs can be printed or exported to other Microsoft Windows programs. GraphROC for Windows also employs a new method, developed by us, for the indirect estimation of health-related limits and change limits from mixed distributions of clinical laboratory data.

    The traditional criteria for acceptability of analytic quality may not be objective in clinical laboratories. To establish quality control procedures intended to enhance Westgard multi-rules for improving the quality of clinical biochemistry tests, we applied the Cp and Cpk quality-control indices to monitor tolerance fitting and systematic variation of clinical biochemistry test results. Daily quality-control data of a large Taiwanese hospital in 2009 were analyzed. The test items were selected based on an Olympus biochemistry machine and included serum albumin, aspartate aminotransferase, cholesterol, glucose and potassium levels. Cp and Cpk values were calculated for normal and abnormal levels, respectively. The tolerance range was estimated with data from 50 laboratories using the same instruments and reagents. The results showed a monthly trend of variation for the five items under investigation. The index values of glucose were lower than those of the other items, and their values were usually quality control, but also for revealing inter-laboratory qualitycontrol capability differences.

    There is increasing awareness of the importance of transforming organisational culture in order to raise safety standards. This paper describes the results obtained from an evaluation of patient safety culture in a sample of clinical laboratories in public hospitals in the Spanish National Health System. A descriptive cross-sectional study was conducted among health workers employed in the clinical laboratories of 27 public hospitals in 2012. The participants were recruited by the heads of service at each of the participating centers. Stratified analyses were performed to assess the mean score, standardized to a base of 100, of the six survey factors, together with the overall patient safety score. 740 completed questionnaires were received (88% of the 840 issued). The highest standardized scores were obtained in Area 1 (individual, social and cultural) with a mean value of 77 (95%CI: 76-78), and the lowest ones, in Area 3 (equipment and resources), with a mean value of 58 (95%CI: 57-59). In all areas, a greater perception of patient safety was reported by the heads of service than by other staff. We present the first multicentre study to evaluate the culture of clinical safety in public hospital laboratories in Spain. The results obtained evidence a culture in which high regard is paid to safety, probably due to the pattern of continuous quality improvement. Nevertheless, much remains to be done, as reflected by the weaknesses detected, which identify areas and strategies for improvement.

    Biosensors for proteins have shown attractive advantages compared to traditional techniques in clinical laboratory diagnosis. In virtue of modern fabrication modes and detection techniques, various immunosensing platforms have been reported on basis of the specific recognition between antigen-antibody pairs. In addition to profit from the development of nanotechnology and molecular biology, diverse fabrication and signal amplification strategies have been designed for detection of protein antigens, which has led to great achievements in fast quantitative and simultaneous testing with extremely high sensitivity and specificity. Besides antigens, determination of antibodies also possesses great significance for clinical laboratory diagnosis. In this review, we will categorize recent immunosensors for proteins by different detection techniques. The basic conception of detection techniques, sensing mechanisms, and the relevant signal amplification strategies are introduced. Since antibodies and antigens have an equal position to each other in immunosensing, all biosensing strategies for antigens can be extended to antibodies under appropriate optimizations. Biosensors for antibodies are summarized, focusing on potential applications in clinical laboratory diagnosis, such as a series of biomarkers for infectious diseases and autoimmune diseases, and an evaluation of vaccine immunity. The excellent performances of these biosensors provide a prospective space for future antibody-detection-based disease serodiagnosis.

    Estimating equations using serum creatinine (SCr) are often used to assess glomerular filtration rate (GFR). Such creatinine (Cr)-based formulae may produce biased estimates of GFR when using Cr measurements that have not been calibrated to reference laboratories. In this paper, we sought to examine the degree of this variation in Cr assays in several laboratories associated with academic medical centers affiliated with the Chronic Renal Insufficiency Cohort (CRIC) Study; to consider how best to correct for this variation, and to quantify the impact of such corrections on eligibility for participation in CRIC. Variability of Cr is of particular concern in the conduct of CRIC, a large multicenter study of subjects with chronic renal disease, because eligibility for the study depends on Cr-based assessment of GFR. A library of 5 large volume plasma specimens from apheresis patients was assembled, representing levels of plasma Cr from 0.8 to 2.4 mg/dl. Samples from this library were used for measurement of Cr at each of the 14 CRIC laboratories repetitively over time. We used graphical displays and linear regression methods to examine the variability in Cr, and used linear regression to develop calibration equations. We also examined the impact of the various calibration equations on the proportion of subjects screened as potential participants who were actually eligible for the study. There was substantial variability in Cr assays across laboratories and over time. We developed calibration equations for each laboratory; these equations varied substantially among laboratories and somewhat over time in some laboratories. The laboratory site contributed the most to variability (51% of the variance unexplained by the specimen) and variation with time accounted for another 15%. In some laboratories, calibration equations resulted in differences in eligibility for CRIC of as much as 20%. The substantial variability in SCr assays across laboratories necessitates calibration

    13% of all drug susceptibility tests (DSTs) performed at a public laboratory in Peru were duplicate. To determine reasons for duplicate requests an online survey was implemented in the e-Chasqui laboratory information system. Results showed that 59.6% of tests were ordered because clinical staff was unaware of ordering guidelines or of a previous result. This shows a benefit of using a web-based system and the lack of laboratory information available to clinical staff in Peru.

    The objective of this paper is to present a brief description of technical solutions for health information system security threats caused by inadequate security and privacy practices in healthcare professionals. A literature search was carried out in ScienceDirect, ACM Digital Library and IEEE Digital Library to find papers reporting technical solutions for certain security problems in information systems used in clinical settings. A total of 17 technical solutions were identified: measures for password security, the secure use of e-mail, the Internet, portable storage devices, printers and screens. Although technical safeguards are essential to the security of healthcare organization's information systems, good training, awareness programs and adopting a proper information security policy are particularly important to prevent insiders from causing security incidents.

    There is little UK-based empirical research on South Asian participation in clinical trials. The predominantly US literature rarely engages with mainstream debates about ethnicity, diversity and difference. This study was prompted by a lack of knowledge about how South Asian people perceive trial involvement and the risks and benefits involved. Face to face interviews were conducted with 25 health professionals (consultants, GPs, nursing staff, academics, non-medically trained trial co-ordinators, LREC and MREC members) and 60 South Asian lay people (20 Indians, 20 Pakistanis and 20 Bangladeshis) who had not taken part in a trial. The study took place in the Leeds and Bradford areas of England. It was found that lay South Asian attitudes towards clinical trial participation focused on similarities rather than differences with the general UK population, suggesting that the relevance of ethnicity should be kept in perspective. There was no evidence of antipathy amongst South Asians to the concept of clinical trials, and awareness was a correlate of social class, education and younger age. Lay factors that might affect South Asian participation in clinical trials included: age; language, social class; feeling of not belonging/mistrust; culture and religion. Approachable patients (of the same gender, social class and fluent in English) tended to be 'cherry picked' to clinical trials. This practice was justified because of a lack of time, resources and inadequate support. South Asian patients might be systematically excluded from trials due to the increased cost and time associated with their inclusion, particularly in relation to the language barrier. Under-representation might also be due to passive exclusion associated with cultural stereotypes. The paper concludes by applying the theoretical framework of institutional racism as a means of making sense of policy and practice. At the same time, caution is advocated against using ethnicity as the only form of

    Laboratory-based surveillance, one of the pillars of monitoring infectious disease trends, relies on data produced in clinical and/or public health laboratories. Currently, diagnostic laboratories worldwide submit strains or samples to a relatively small number of reference laboratories for characterisation and typing. However, with the introduction of molecular diagnostic methods and sequencing in most of the larger diagnostic and university hospital centres in high-income countries, the distinction between diagnostic and reference/public health laboratory functions has become less clear-cut. Given these developments, new ways of networking and data sharing are needed. Assuming that clinical and public health laboratories may be able to use the same data for their own purposes when sequence-based testing and typing are used, we explored ways to develop a collaborative approach and a jointly owned database (TYPENED) in the Netherlands. The rationale was that sequence data - whether produced to support clinical care or for surveillance -can be aggregated to meet both needs. Here we describe the development of the TYPENED approach and supporting infrastructure, and the implementation of a pilot laboratory network sharing enterovirus sequences and metadata.

    This study investigated professional practice and common test use among clinical neuropsychologists engaging in forensic assessment.  Doctorate-level psychologists active in the practice of neuropsychology and on the INS and NAN membership listings (n = 502) were surveyed about their demographics, professional practice, and common test use. Participants who reported engaging in forensic practice (n = 255) were further surveyed about their forensic practice. Forensic participants were more likely to be male and Caucasian, and reported higher ages, more years of professional experience, and a higher prevalence of board certification. While characteristics of their professional and forensic practice varied, forensic participants reported spending most of their professional time conducting neuropsychological assessments with adult clients in a private or group practice setting, focusing on civil referrals and civil legal questions involving older adult issues, developmental issues, head injury, and psychiatric issues. Common test use across neuropsychological assessment domains is presented for board-certified forensic participants (n = 77). An examination of these results reveals that the current pattern of test use is similar to the results of a more general survey of neuropsychological test use.  The findings provide insight into the practice of forensic neuropsychological assessment, and further establish the admissibility of neuropsychological evidence in the United States legal system. Results will be useful for clinical neuropsychologists, field leaders, and legal professionals hoping to gain insight into the role of clinical neuropsychology in civil and criminal legal decision-making.

    The rapid scale-up of the care and treatment programs in Tanzania during the preceding 4 years has greatly increased the demand for quality laboratory services for diagnosis of HIV and monitoring patients during antiretroviral therapy. Laboratory services were not in a position to cope with this demand owing to poor infrastructure, lack of human resources, erratic and/or lack of reagent supply and commodities, and slow manual technologies. With the limited human resources in the laboratory and the need for scaling up the care and treatment program, it became necessary to install automated equipment and train personnel for the increased volume of testing and new tests across all laboratory levels. With the numerous partners procuring equipment, the possibility of a multitude of equipment platforms with attendant challenges for procurement of reagents, maintenance of equipment, and quality assurance arose. Tanzania, therefore, had to harmonize laboratory tests and standardize laboratory equipment at different levels of the laboratory network. The process of harmonization of tests and standardization of equipment included assessment of laboratories, review of guidelines, development of a national laboratory operational plan, and stakeholder advocacy. This document outlines this process.

  15. Simple clinical and laboratory predictors of Chikungunya versus dengue infections in adults.

    Full Text Available BACKGROUND: Dengue and chikungunya are co-circulating vector-borne diseases with substantial overlap in clinical presentations. It is important to differentiate between them during first presentation as their management, especially for dengue hemorrhagic fever (DHF, is different. This study compares their clinical presentation in Singapore adults to derive predictors to assist doctors in diagnostic decision-making. METHODS: We compared 117 patients with chikungunya infection diagnosed with reverse transcription-polymerase chain reaction (RT-PCR with 917 dengue RT-PCR-positive adult patients (including 55 with DHF. We compared dengue fever (DF, DHF, and chikungunya infections by evaluating clinical characteristics of dengue and chikungunya; developing classification tools via multivariate logistic regression models and classification trees of disease etiology using clinical and laboratory factors; and assessing the time course of several clinical variables. FINDINGS: At first presentation to hospital, significantly more chikungunya patients had myalgia or arthralgia, and fewer had a sore throat, cough (for DF, nausea, vomiting, diarrhea, abdominal pain, anorexia or tachycardia than DF or DHF patients. From the decision trees, platelets <118 × 10(9/L was the only distinguishing feature for DF versus chikungunya with an overall correct classification of 89%. For DHF versus chikungunya using platelets <100 × 10(9/L and the presence of bleeding, the overall correct classification was 98%. The time course analysis supported platelet count as the key distinguishing variable. INTERPRETATION: There is substantial overlap in clinical presentation between dengue and chikungunya infections, but simple clinical and laboratory variables can predict these infections at presentation for appropriate management.

    The polymerase chain reaction (PCR) technique, one of the most commonly applied methods in diagnostic and molecular biology, has a frustrating downside: the occurrence of false-positive signals due to contamination. In previous research, various DNA decontamination methods have been developed to overcome this limitation. Unfortunately, the use of random or poorly focused sampling methods for monitoring air and/or object surfaces leads to the incomplete elimination during decontamination procedures. We herein attempted to develop a novel DNA decontamination method (environmental surveillance, including surface and air sampling) and quality management program for clinical molecular diagnostic laboratories (or clinical PCR laboratories). Here, we performed a step-by-step evaluation of current DNA decontamination methods and developed an effective procedure for assessing the presence of decontaminating DNA via PCR analysis. Performing targeted environmental surveillance by sampling, which reached optimal performance over 2 weeks, and the decontamination process had been verified as reliable. Additionally, the process was validated to not affect PCR amplification efficiency based on a comparative study. In this study, effective guidelines for DNA decontamination were developed. The method employed ensured that surface DNA contamination could be effectively identified and eliminated. Furthermore, our study highlighted the importance of overall quality assurance and good clinical laboratory practices for preventing contamination, which are key factors for compliance with regulatory or accreditation requirements. Taken together, we provided the evidence that the presented scheme ranged from troubleshooting to the elimination of surface contamination, could serve as critical foundation for developing regular environmental surveillance guidelines for PCR laboratories. © 2017 Wiley Periodicals, Inc.

    Background One-third of Americans use social media websites as a source of health care information. Twitter, a microblogging site that allows users to place 280-character posts—or tweets—on the Web, is emerging as an important social media platform for health care. However, most guidelines on medical professionalism on social media are based on expert opinion. Objective This study sought to examine if provider Twitter profiles with educational tweets were viewed as more professional than profiles with personal tweets or a mixture of the two, and to determine the impact of provider gender on perceptions of professionalism in an academic obstetrics and gynecology clinic. Methods This study randomized obstetrics and gynecology patients at the University of Michigan Von Voigtlander Clinic to view one of six medical provider Twitter profiles, which differed in provider gender and the nature of tweets. Each participant answered 10 questions about their perception of the provider’s professionalism based on the Twitter profile content. Results The provider profiles with educational tweets alone received higher mean professionalism scores than profiles with personal tweets. Specifically, the female and male provider profiles with exclusively educational tweets had the highest and second highest overall mean professionalism ratings at 4.24 and 3.85, respectively. In addition, the female provider profiles received higher mean professionalism ratings than male provider profiles with the same content. The female profile with mixed content received a mean professionalism rating of 3.38 compared to 3.24 for the male mixed-content profile, and the female profile with only personal content received a mean professionalism rating of 3.68 compared to 2.68 for the exclusively personal male provider profile. Conclusions This study showed that in our obstetrics and gynecology clinic, patients perceived providers with educational profiles as more professional than those with a

    In the early 1960s, Joachim Brugsch, one of the founders of Clinical Chemistry and Laboratory Medicine (CCLM) (then Zeitschrift für Klinische Chemie), had the idea to found a journal in the upcoming field of clinical chemistry. He approached Ernst Schütte, who was associated with the De Gruyter publishing house through another journal, to participate, and Schütte thus became the second founder of this Journal. The aim was to create a vehicle allowing the experts to express their opinions and raise their voices more clearly than they could in a journal that publishes only original experimental papers, a laborious and difficult, but important endeavor, as the profession of clinical chemistry was still in the early stages of development at this time. The first issue of this Journal was published in early 1963, and today, we are proud to celebrate the 50th anniversary of CCLM. This review describes the development of this Journal in light of the political situation of the time when it was founded, the situation of the publisher Walter De Gruyter after the erection of the Berlin Wall, and the development of clinical chemistry, and later on, laboratory medicine as a well-acknowledged discipline and profession.

    Large clinical genomics studies using next generation DNA sequencing require the ability to select and track samples from a large population of patients through many experimental steps. With the number of clinical genome sequencing studies increasing, it is critical to maintain adequate laboratory information management systems to manage the thousands of patient samples that are subject to this type of genetic analysis. To meet the needs of clinical population studies using genome sequencing, we developed a web-based laboratory information management system (LIMS) with a flexible configuration that is adaptable to continuously evolving experimental protocols of next generation DNA sequencing technologies. Our system is referred to as MendeLIMS, is easily implemented with open source tools and is also highly configurable and extensible. MendeLIMS has been invaluable in the management of our clinical genome sequencing studies. We maintain a publicly available demonstration version of the application for evaluation purposes at http://mendelims.stanford.edu. MendeLIMS is programmed in Ruby on Rails (RoR) and accesses data stored in SQL-compliant relational databases. Software is freely available for non-commercial use at http://dna-discovery.stanford.edu/software/mendelims/.

    Introduction As part of the health care quality and safety policy in France, Professional Practice Assessment (P.P.A.) are mandatory in the health services 'certification' process. We present our study regarding the pertinence of Positron Emission Tomography (PET) indications in oncology. Materials and methods A multidisciplinary task group used the Quick Audit method with two rounds of 100 request forms each. The assessment list of criteria comprised four items of decreasing relevance grading the PET scans clinical indications, which were derived from the three French published guidelines (S.O.R. [F.N.C.L.C.C]., 'Guide du bon usage des examens d'imagerie medicale' [S.F.R.-S.F.M.N.], 'Guide pour la redaction de protocoles pour la TEP au F.D.G. en cancerologie' [S.F.M.N.]) and five additional items: clinical information, patient's body weight, previous treatments dates, diabetes, claustrophobia. Results The first round showed that 68% of the requested scans corresponded to the two most relevant groups of indications (S.O.R. Standards and Options). The request forms were correctly filled in regarding the clinical information, but this was not the case for the other items we tested. Several actions were conducted: dedicated PET request form, availability of the S.O.R. on the hospital intranet, boost of the referring physicians awareness during the multidisciplinary oncology meetings (Reunions de Concertation Pluridisciplinaires RCP). The second round showed a better pertinence of the PET scans indications (75% versus 68%); the patient's body weight was more frequently mentioned on the request form. Discussion This study is an example of P.P.A. in our discipline. It led to an improvement of the oncologic PET scans clinical indications in our hospital. This work is pursued in everyday discussion with the referring clinicians, especially during the RCP. (authors)

    Clinical information is needed to assess the causal relationship between a drug and an adverse drug reaction (ADR) in a reliable way. Little is known about the level of relevant clinical information about the ADRs reported by patients. The aim was to determine to what extent patients report relevant clinical information about an ADR compared with their healthcare professional. A retrospective analysis of all ADR reports on the same case, i.e., cases with a report from both the patient and the patient's healthcare professional, selected from the database of the Dutch Pharmacovigilance Center Lareb, was conducted. The extent to which relevant clinical information was reported was assessed by trained pharmacovigilance assessors, using a structured tool. The following four domains were assessed: ADR, chronology, suspected drug, and patient characteristics. For each domain, the proportion of reported information in relation to information deemed relevant was calculated. An average score of all relevant domains was determined and categorized as poorly (≤45%), moderately (from 46 to 74%) or well (≥75%) reported. Data were analyzed using a paired sample t test and Wilcoxon signed rank test. A total of 197 cases were included. In 107 cases (54.3%), patients and healthcare professionals reported a similar level of clinical information. Statistical analysis demonstrated no overall differences between the groups (p = 0.126). In a unique study of cases of ADRs reported by patients and healthcare professionals, we found that patients report clinical information at a similar level as their healthcare professional. For an optimal pharmacovigilance, both healthcare professionals and patient should be encouraged to report.

    Context: Peer-assisted learning (PAL) has been recommended as an educational strategy to improve students' skill acquisition and supplement the role of the clinical instructor (CI). How frequently students actually engage in PAL in different settings is unknown. Objective: To determine the perceived frequency of planned and unplanned PAL (peer modeling, peer feedback and assessment, peer mentoring) in different settings. Design: Cross-sectional study. Setting: Laboratory and collegiate clinical settings. Patients or Other Participants: A total of 933 students, 84 administrators, and 208 CIs representing 52 (15%) accredited athletic training education programs. Intervention(s): Three versions (student, CI, administrator) of the Athletic Training Peer Assisted Learning Survey (AT-PALS) were administered. Cronbach α values ranged from .80 to .90. Main Outcome Measure(s): Administrators' and CIs' perceived frequency of 3 PAL categories under 2 conditions (planned, unplanned) and in 2 settings (instructional laboratory, collegiate clinical). Self-reported frequency of students' engagement in 3 categories of PAL in 2 settings. Results: Administrators and CIs perceived that unplanned PAL (0.39 ± 0.22) occurred more frequently than planned PAL (0.29 ± 0.19) regardless of category or setting (F1,282 = 83.48, P < .001). They perceived that PAL occurred more frequently in the collegiate clinical (0.46 ± 0.22) than laboratory (0.21 ± 0.24) setting regardless of condition or category (F1,282 = 217.17, P < .001). Students reported engaging in PAL more frequently in the collegiate clinical (3.31 ± 0.56) than laboratory (3.26 ± 0.62) setting regardless of category (F1,860 = 13.40, P < .001). We found a main effect for category (F2,859 = 1318.02, P < .001), with students reporting they engaged in peer modeling (4.01 ± 0.60) more frequently than peer mentoring (2.99 ± 0.88) (P < .001) and peer assessment and feedback (2.86 ± 0.64) (P < .001). Conclusions: Participants

    Full Text Available Nowadays, the clinical skill learning in dental education has begun in pre-clinic, known as Clinical Skill Laboratory (CSL which needs human resources, many and expensive tools and manikins, and enough times for practise. One of the method used in CSL in dental education is PeerAssisted Learning (PAL defined as “the development of knowledge and skill through active help and support among status equals or match companions”. This paper aims is to explain the role of PAL method to improve the effectivity of CSL learning in dental education in preclinical stage. Reviewing on the relevant literatures regarding peer assisted learning on the implementation of the clinical skill laboratory in dental education. The effectivity of CSL learning needs close supervision and individual feedback, so enough tutors is important through the process. This PAL method considered to be helpfull with the increasing numbers of dental students and the limitation of staff faculty. This method is found feasible, well accepted by peer-tutors and students, and can be as effective as conventional learning method. This is also useful for peer-teacher because they more intrinsically motivated, have higher conceptual learning scores, and perceive themselves to be more actively engaged with the environment than students who learn in order to be tested.  However, there are several limitation of this method. The contact time between students and medical doctors may decrease significantlyand it does not seem to be generally qualified to transfer such complex procedures.It also needs peer-teachers training and a detailed manual. Questions concerning the cost-effectiveness and profitability of student tutor-guided technical skills training may thus arise. But one institution that implemented this method states that the majority of their tutors decided to continue their teaching activity in the skills lab and that these experienced tutors, in addition to established faculty staff

    This paper discusses the biological basis of new treatment strategies that are being introduced into the clinic in the form of controlled clinical trials. There is an increasing awareness of the need for quality assurance in the design, execution and analysis of these trials. However there is little awareness of the need to critically assess the biological basis of the trial design, to ensure that no other biological principles have been contravened in the attempt to optimise just one of the many parameters that determine the differential in sensitivity between tumours and normal tissues. Some examples are given of the changes that have recently occurred in the laboratory interpretation of both the mechanism of action and the therapeutic gain of several novel approaches. If these are not considered, the carefully controlled clinical trials may be wasted, because of being based on an incomplete consideration of all the interconnected biological factors. (author)
