    Assessing immunophenotyping performance: Proficiency-validation for adopting improved flow cytometry methods

    CYTOMETRY, Issue 4 2007
    Lance E. Hultin
    Abstract Background: The continuous improvement and evolution of immune cell phenotyping requires periodic upgrading of laboratory methods and technology. Flow cytometry laboratories that are participating in research protocols sponsored by the NIAID are required to perform "switch" studies to validate performance before methods for T-cell subset analysis can be changed. Methods: Switch studies were conducted among the four flow cytometry laboratories of the Multicenter AIDS Cohort Study (MACS), comparing a 2-color, lyse-wash method and a newer, 3-color, lyse no-wash method. Two of the laboratories twice failed to satisfy the criteria for acceptable differences from the previous method. Rather than repeating more switch studies, these laboratories were allowed to adopt the 3-color, lyse no-wash method. To evaluate the impact of the switch to the new method at these two sites, their results with the new method were evaluated within the context of all laboratories participating in the NIH-NIAID-Division of AIDS Immunology Quality Assurance (IQA) proficiency-testing program. Results: Laboratory performance at these two sites substantially improved relative to the IQA standard test results. Variation across the four MACS sites and across replicate samples was also reduced. Conclusions: Although switch studies are the conventional method for assessing comparability of laboratory methods, two alternatives to the requirement of repeating failed switch studies should be considered: (1) test the new method and assess performance on the proficiency testing reference panel, and (2) prior to adoption of the new methods, use both the old and the new method on the reference panel samples and demonstrate that performance with the new method is better according to standard statistical procedures. These alternatives may help some laboratories' transition to a new and superior methodology more quickly than if they are required to attempt multiple, serial switch studies. © 2007 Clinical Cytometry Society [source]


    European guidelines for quality assurance in cervical cancer screening: recommendations for cytology laboratories,

    CYTOPATHOLOGY, Issue 2 2007
    H. G. Wiener
    The quality of a cervical cytology laboratory depends on adequate handling and staining of the samples, screening and interpretation of the slides and reporting of the results. These guidelines give an overview of procedures recommended in Europe to manage the balance between best patient care possible, laboratory quality assurance and cost effectiveness and will be published as a chapter 4 in the European Guidelines for Quality Assurance in Cervical Cancer Screening. The laboratory guidelines include protocols for personnel and organisation, material requirements, handling and analysing cervical samples, recording of results, quality management and communication. The section on quality management is comprehensive and includes protocols for all aspects of internal and external quality assurance. The guidelines are extensively referenced and as far as possible the recommendations are evidence-based. [source]


    A national survey of the current state of screening services for diabetic retinopathy: ABCD,Diabetes UK survey of specialist diabetes services 2006

    DIABETIC MEDICINE, Issue 12 2009
    D. K. Nagi
    Abstract The main aims were to ascertain the progress made in the implementation of retinal screening services and to explore any barriers or difficulties faced by the programmes. The survey focused on all the essential elements for retinal screening, including assessment and treatment of screen-positive cases. Eighty-five per cent of screening programmes have a coordinated screening service and 73% of these felt that they have made significant progress. Eighty-five per cent of screening units use ,call and recall' for appointments and 73.5% of programmes follow the National Screening Committee (NSC) guidance. Although many units worked closely with ophthalmology, further assessment and management of screen-positive patients was a cause for concern. The fast-track referral system, to ensure timely and appropriate care, has been difficult to engineer by several programmes. This is demonstrated by 48% of programmes having waiting lists for patients identified as needing further assessment and treatment for retinopathy. Ophthalmology service for people with diabetic retinopathy was provided by a dedicated ophthalmologist in 89.4% of the programmes. Sixty-six per cent of the programmes reported inadequate resources to sustain a high-quality service, while 26% highlighted the lack of infrastructure and 49% lacked information technology (IT) support. In conclusion, progress has been made towards establishing a national screening programme for diabetic retinopathy by individual screening units, with a number of programmes providing a structured retinal screening service. However, programmes face difficulties with resource allocation and compliance with Quality Assurance (QA) standards, especially those which apply to ophthalmology and IT support. Screening programmes need to be resourced adequately to ensure comprehensive coverage and compliance with QA. [source]


    Quality assurance and benchmarking: an approach for European dental schools

    EUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 3 2007
    M. L. Jones
    Abstract:, This document was written by Task Force 3 of DentEd III, which is a European Union funded Thematic Network working under the auspices of the Association for Dental Education in Europe (ADEE). It provides a guide to assist in the harmonisation of Dental Education Quality Assurance (QA) systems across the European Higher Education Area (EHEA). There is reference to the work, thus far, of DentEd, DentEd Evolves, DentEd III and the ADEE as they strive to assist the convergence of standards in dental education; obviously QA and benchmarking has an important part to play in the European HE response to the Bologna Process. Definitions of Quality, Quality Assurance, Quality Management and Quality Improvement are given and put into the context of dental education. The possible process and framework for Quality Assurance are outlined and some basic guidelines/recommendations suggested. It is recognised that Quality Assurance in Dental Schools has to co-exist as part of established Quality Assurance systems within faculties and universities, and that Schools also may have to comply with existing local or national systems. Perhaps of greatest importance are the 14 ,requirements' for the Quality Assurance of Dental Education in Europe. These, together with the document and its appendices, were unanimously supported by the ADEE at its General Assembly in 2006. As there must be more than one road to achieve a convergence or harmonisation standard, a number of appendices are made available on the ADEE website. These provide a series of ,toolkits' from which schools can ,pick and choose' to assist them in developing QA systems appropriate to their own environment. Validated contributions and examples continue to be most welcome from all members of the European dental community for inclusion at this website. It is realised that not all schools will be able to achieve all of these requirements immediately, by definition, successful harmonisation is a process that will take time. At the end of the DentEd III project, ADEE will continue to support the progress of all schools in Europe towards these aims. [source]


    The Relationship between Health Plan Performance Measures and Physician Network Overlap: Implications for Measuring Plan Quality

    HEALTH SERVICES RESEARCH, Issue 4 2010
    Daniel D. Maeng
    Objective. To examine the extent to which health plan quality measures capture physician practice patterns rather than plan characteristics. Data Source. We gathered and merged secondary data from the following four sources: a private firm that collected information on individual physicians and their health plan affiliations, The National Committee for Quality Assurance, InterStudy, and the Dartmouth Atlas. Study Design. We constructed two measures of physician network overlap for all health plans in our sample and linked them to selected measures of plan performance. Two linear regression models were estimated to assess the relationship between the measures of physician network overlap and the plan performance measures. Principal Findings. The results indicate that in the presence of a higher degree of provider network overlap, plan performance measures tend to converge to a lower level of quality. Conclusions. Standard health plan performance measures reflect physician practice patterns rather than plans' effort to improve quality. This implies that more provider-oriented measurement, such as would be possible with accountable care organizations or medical homes, may facilitate patient decision making and provide further incentives to improve performance.

    EQAS for peripheral blood morphology in Spain: a 6-year experience

    INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 6 2008
    G. GUTIÉRREZ
    Summary The Spanish haematology external quality assessment scheme (EQAS), established in 1984, is run by the Spanish Haematology and Haemotherapy Association (AEHH) [Quality Assurance in Health Care 3 (1991) 75] and functions to evaluate the quality and reproducibility of the assessment of diagnostic samples by clinical laboratories. The Hospital Clinic of the University of Barcelona (HCB) serves as the EQAS Coordination Centre and follows the guidelines established by the International Committee for Standardization in Haematology [Annali dell'Istituto superiore di Sanità 31 (1995) 95; International Journal of Hematology 68 (1998) 45]. During the period 2001,2006, replicates of 25 different blood films were sent to 604 EQAS participants for cell morphology evaluation. Some patient details corresponding to the samples were disclosed, such us age, sex, haemoglobin value and white blood cell count. The participants were asked to select up to four significant morphology features using a coding list, provided by the Coordination Centre, which included significant morphological alterations that appear in haematopoietic cells. For each survey, individual results were assessed against the morphological reference results (MRR) established by the Cytology Group of the AEHH (,true' answers). This paper describes the organization of the 6-year-long study and the evaluation of laboratory performance for blood smear interpretation by the Spanish haematology EQAS. Different performance levels were detected relative to the laboratory category. Laboratories providing services to hospitalized patients showed higher performances compared with laboratories providing services to nonhospitalized patients. Pathological lymphoid cells were the most difficult to identify by the participants. To improve the results in EQAS peripheral blood morphology, the development of specific cytology educational trainings is discussed. [source]


    Peer observation of teaching in the online environment: an action research approach

    JOURNAL OF COMPUTER ASSISTED LEARNING, Issue 5 2008
    D. Swinglehurst
    Abstract This paper describes a collaborative action research approach used to explore peer observation of teaching (POT) within the online environment. Although POT has become familiar in face-to-face teaching contexts, little is understood of its potential role in online settings. We conducted ,virtual' focus groups to explore the experience and views of 28 teachers and subjected our data to a thematic analysis. This informed the implementation of an innovative programme of POT, ,Peer-to-peer Reflection on Pedagogical Practice' (PROPP) among tutors of a Web-based MSc in International Primary Health Care at University College London. Modeled on an action learning set, the programme encourages collaborative reflection on teaching practices, based on participants' specific examples of online teaching. The PROPP model is consistent with Quality Enhancement, which we distinguish from Quality Assurance. Here, we describe the implementation of the PROPP programme within an action research framework and identify the factors that we consider critical to the success of peer observation within online courses. We highlight examples of aspects of teaching that have been discussed within the PROPP programme and offer suggestions of the kinds of evidence that could be incorporated into a portfolio to demonstrate the effectiveness of such an initiative.

    Quality assurance program for spent radioactive sealed sources in Egypt

    QUALITY ASSURANCE JOURNAL, Issue 2 2009
    Yasser T. Mohamed
    Abstract Effective implementation of the Hot Laboratories Center Quality Assurance Program (QAP) is dependent on the efforts at all levels of all participants. Management is responsible for defining quality, developing appropriate plans to attain quality, and supporting the workers in the pursuit of quality. QA organizations of the program participants are responsible for verifying the achievement of quality in the implementation of the Hot Laboratories Center QA program. A written QAP shall be developed, implemented, and maintained. The QAP describes the organizational structure, functional responsibilities, levels of authority, and interfaces for those managing, performing, and assessing the work. The QAP shall describe the management processes, including planning, scheduling, and resource considerations. The organization, responsibilities/authorities of all participants, internal and external interfaces, and lines of communication should be established during the conceptual phase. Quality Assurance (QA) as an essential management tool is being strongly applied in the area of predisposal of Spent Radioactive Sealed Sources (SRSS). Quality Control is now considered as part of the planning and systematic actions of QA. To ensure compliance with the requirements, and to assure the envisaged behavior of the SRSS package and disposal system, a QAP for all stages of SRSS management, including SRSS conditioning, transportation, storage, and disposal are required.

    Test substance characterization for the EPA: what you've always wanted to know but were afraid to ask,

    QUALITY ASSURANCE JOURNAL, Issue 3-4 2007
    William Barta
    Abstract The Society of Quality Assurance (SQA) GLP Specialty Section, a member of the SQA Regulatory Forum, is a group of participants from the regulated community which provides insight and guidance to our membership and the regulated community. The Specialty Section has encountered several participants who want to know what types of information and data are needed during an inspection by the US EPA's Office of Enforcement and Compliance Assurance (OECA). The OECA is responsible for monitoring studies submitted to the Office of Pesticide Programs in support of pesticide registrations as defined under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). All submitted studies are to be conducted according to the FIFRA US Good Laboratory Practice Standards (GLPS). The GLPS contain specific language concerning the characterization of test, control and reference substances used in these studies. This article clarifies those requirements and provides perspective on the EPA expectations on meeting those requirements. The topics of discussion include: regulatory requirements responsibilities of the testing facility management, study director, Quality Assurance Unit and the sponsor preparing for an inspection overview of data to be made available at the time of inspection composition of a Certificate of Analysis.

    Integrating maintenance activities and Quality Assurance in a research and development (R&D) system

    QUALITY ASSURANCE JOURNAL, Issue 4 2006
    Debasish Basak
    Abstract A well-balanced maintenance program furnishes information and instructions to personnel involved in maintaining existing equipment, provides current information on the availability and location of maintenance materials, improves utilization of labor forces and increases equipment reliability. Planned and preventive maintenance procedures where components are serviced and changed when they approach the end of their useful lives can be augmented by suitable means, which continuously check vital machine functions. Quality Assurance can be seen as a management system that brings maintenance activities undertaken by all parties under control with the aim of preventing things from going wrong and costing time, effort and money to put them right. An attempt has been made to highlight the integration of maintenance activities with Quality Assurance as a whole in a research and development (R&D) system. Copyright © 2006 John Wiley & Sons, Ltd.

    The regulatory and business roles of a Study Director

    QUALITY ASSURANCE JOURNAL, Issue 4 2005
    Celeste A. Rose
    Abstract The role of Study Director can be a challenging one with technical, administrative, and compliance responsibilities. The Study Director often does not have direct responsibility for personnel and other resources required for his/her studies. In this article, we have attempted to identify traits and mechanisms to help the Study Director do his/her job in a professional and compliant manner. In addition to regulatory and scientific expertise, Study Director quality attributes include possession of appropriate soft skills and character traits and are key to the success of a study. Study Directors must have an aptitude for effective communication, relationship building, training, mentoring, and delegation. While these soft skills/desirable traits often require additional effort on the part of the Study Director, they have a large impact on the rate of success, efficiency, and compliance of the study overall. The workshop presented by the authors took a 'hands-on' approach building on the creativity, and experience of Study Directors, supervisors, managers, and Quality Assurance (QA) personnel who participated. The participants deliberated problem scenarios from a Study Director's perspective. The tables and discussion in this article summarize compliant solutions, which arose from the resourcefulness that comes from experience of the participants. Copyright © 2005 John Wiley & Sons, Ltd.

    GIQAR position paper on ,Archiving and Good Laboratory Practice',

    QUALITY ASSURANCE JOURNAL, Issue 4 2005
    M. M. Brunetti
    Abstract Archiving of documents and specimens generated during a non-clinical laboratory study is a basic Good Laboratory Practice (GLP) requirement. The records and materials that should be archived as well as the characteristics and the organisation of archive facilities are addressed in the OECD Series on Principles of Good Laboratory Practice No. 1 (OECD Principles of Good Laboratory Practice (as revised in 1997) [1]. However, in recent years, questions concerning archiving have been raised and the need for a more detailed guidance on this matter has become evident The aim of the Society for Applied Pharmacological Sciences/Italian Group of Quality Assurance in Research (SSFA/GIQAR) working group on ,Archiving according to GLP' was to issue a position paper, present it for discussion in an ad hoc round table with representatives of the Italian GLP monitoring authority to promote common standards and to provide additional recommendations on storage and retention of records.

    Principles in quality assurance.

    QUALITY ASSURANCE JOURNAL, Issue 1 2003
    Part 2.
    Abstract In order to achieve and sustain effective compliance with the quality regulations, an understanding of the rationale for compliance must be developed throughout an organization. Developing such an organizational understanding is difficult to attain through training based solely on the text of the regulations or the company's Standard Operating Procedures (SOPs). These do have their place, but there is too much information, and the effects of training dissipate rapidly because personnel cannot effectively retain detailed information. In our organization, we undertook a process of simplification of the regulations, in an attempt to define the smallest number of basic quality principles that are embodied in Good Laboratory Practice (GLP) and associated regulations. The systematic application of these quality principles is a mechanism by which Quality Assurance (QA) can be clear and consistent in its monitoring and training activities. This process empowers all personnel to make correct compliance decisions without having to consult the detail of the regulations at every turn. The establishment and application of this concept at a bioanalytical contract research laboratory is described in this article. Copyright © 2003 John Wiley & Sons, Ltd. [source]


    Principles in quality assurance.

    QUALITY ASSURANCE JOURNAL, Issue 4 2002
    Part 1.
    Abstract The regulated pharmaceutical industry is an ocean of complexity and detail through which Quality Assurance (QA) professionals must steer the best course, playing a crucial role in the profitability of the industry and the well-being of patients. How best to keep the 'good ship' QA stable and effective while being battered by the numerous changing priorities, last-minute demands, or unforeseen events, is a challenge to us all, and the subject of this paper. The ideas presented here are simple, perhaps simplistic, and stem from the idea that, in order to be effective in this complex environment, we have to find some fundamental unifying concepts that can be applied consistently to our work. Semantics aside, we will consider these unifying concepts to be 'principles' and this paper will describe their definition and application within a bioanalytical Contract Research Organization (CRO).

    Meeting the challenges of implementing good laboratory practices compliance in a university setting

    QUALITY ASSURANCE JOURNAL, Issue 1 2002
    Sandra Hancock
    Abstract The number of university laboratories participating in good laboratory practices (GLP) studies is on the rise, as evidenced by the increase in university personnel that have joined the Society of Quality Assurance (SQA) during the past decade. However, the road to GLP compliance in the university setting has significant challenges. To evaluate how universities have implemented and managed GLP studies, a survey was conducted of SQA members with a university address. The results are described in this article. At Virginia-Maryland Regional College of Veterinary Medicine (VMRCVM), we have been participating in GLP studies since 1989. Studies are conducted by research or clinical faculty members, with quality assurance (QA) provided by the College Quality Assurance Unit. Since the inception of our GLP Program, VMRCVM has made significant progress toward meeting the challenges of regulatory compliance. Copyright © 2002 John Wiley & Sons, Ltd. [source]

    Qualitätssicherung bei der Verwendung von hochfestem Beton

    BETON- UND STAHLBETONBAU, Issue 2 2005
    Frank Dehn Dr.-Ing.
    Die Verwendung von hochfestem Beton hat in den letzten Jahren stetig zugenommen. Dies belegen mehrere nationale und internationale Bauvorhaben [1], [2], [3]. Als Hauptargumente für die Verwendung dieser Betone werden vielfach die verbesserten Dauerhaftigkeitseigenschaften und die statisch-konstruktiven Aspekte, wie z. B. die Reduzierung von Überbaudicken, genannt. Aus Sicht der Betontechnologie sollen in den nachfolgenden Abschnitten einige Aspekte der Qualitätssicherung für hochfesten Beton beschrieben werden. Hinsichtlich der praktischen Erfahrungen mit hochfestem Beton im Brückenbau wird auf den folgenden Beitrag "Brücken aus hochfestem Beton , Praxiserfahrungen mit Pilotprojekten in Sachsen und Thüringen" auf Seite 106 bis 115 in diesem Heft verwiesen. Quality Assurance for the use of ready-mixed High Strength Concrete (HSC). The application of high strength concretes has been increased continuously in the recent years. This is shown by several national and international construction projects [1], [2], [3]. As main criterions for the use of these concretes improved durability properties but also static-constructive aspects are mentioned, e.g. the reduction of superstructure thicknesses. In the following chapters from a concrete technological point of view some aspects for a quality assurance of high strength concrete are described. Some practical experiences with high-strength concrete for bridges constructions are described in paper "Brücken aus hochfestem Beton , Praxiserfahrungen mit Pilotprojekten in Sachsen und Thüringen" on p. 106 to 115 in this magazine.

    Quality assurance of specialised treatment of eating disorders using large-scale internet-based collection systems: Methods, results and lessons learned from designing the Stepwise database

    EUROPEAN EATING DISORDERS REVIEW, Issue 4 2010
    Andreas Birgegård
    Abstract Computer-based quality assurance of specialist eating disorder (ED) care is a possible way of meeting demands for evaluating the real-life effectiveness of treatment, in a large-scale, cost-effective and highly structured way. The Internet-based Stepwise system combines clinical utility for patients and practitioners, and provides research-quality naturalistic data. Stepwise was designed to capture relevant variables concerning EDs and general psychiatric status, and the database can be used for both clinical and research purposes. The system comprises semi-structured diagnostic interviews, clinical ratings and self-ratings, automated follow-up schedules, as well as administrative functions to facilitate registration compliance. As of June 2009, the system is in use at 20 treatment units and comprises 2776 patients. Diagnostic distribution (including subcategories of eating disorder not otherwise specified) and clinical characteristics are presented, as well as data on registration compliance. Obstacles and keys to successful implementation of the Stepwise system are discussed, including possible gains and on-going challenges inherent in large-scale, Internet-based quality assurance.

    Bacteriological quality of skin-moisturizing creams and lotions distributed in a tropical developing country

    JOURNAL OF APPLIED MICROBIOLOGY, Issue 5 2001
    I.N. Okeke
    Aims: To evaluate the bacteriological quality of skin moisturizing products in the South-west part of Nigeria and study factors predisposing their bacterial contamination under tropical conditions. Methods and Results: Viable counts for bacteria exceeded 103 cfu ml,1or cfu g,1 in 8 (16·3%) commercially available creams and lotions at time of purchase. Escherichia coli (8), Pseudomonas spp. (7), Staphylococcus spp. (9) and Bacillus spp. (6) were the most commonly recovered bacteria. Following use by volunteers, the proportion of E. coli and other Gram-negative organisms recovered increased. Organic matter, particularly in the absence of preservatives, enhanced survival and growth of bacteria in creams stored under ambient tropical conditions during challenge experiments. Conclusions: Contaminated products are relatively uncommon but some products present a potential health hazard because they are unable to suppress the growth of organisms of likely faecal origin during use. Significance and Impact of the Study: Quality assurance during manufacture, pack size, preservative evaluation, organic matter and water content were identified as factors to be considered during the development of creams and lotions for use in tropical developing countries.

    Quality assurance for oral anticoagulation self management: a cluster randomized trial

    JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 3 2008
    E. T. MURRAY
    Summary.,Background and aims:,External quality assessment (EQA) should be an inherent component of patient self management (PSM) of oral anticoagulation. The aim of this study was to evaluate methods of EQA for patients within a cluster randomized trial. Method:,After development of methods, general practises were randomly allocated to a formal EQA scheme of patients performing the test independently at home or at their practise with supervision. The supervised group of practises was further sub divided to test two other EQA methods: (i) venous sample compared with patients' point of care (POC) device; and (ii) patients POC compared with reference POC. Primary trial outcome measure was reliability of results from the formal scheme taking into account adherence and test errors. Results:,Proportion of EQA scheme tests in range was 633/836 (75.7%). Proportion in range was significantly higher in group performing independently compared with supervised group, 80.1% vs. 71.5% respectively, P = 0.02. Sixty-six percent of tests were in range with venous compared with patients POC, and 88% in patients POC compared with reference POC. Conclusion:,Patients are able to undertake a formal EQA scheme and perform more reliably at home independently. There are satisfactory alternatives if a formal scheme is not acceptable. [source]

    Quality assurance in medical and public health genetics services: A systematic review,

    AMERICAN JOURNAL OF MEDICAL GENETICS, Issue 3 2009
    Ann F. Chou
    Abstract As genetic services grow in scope, issues of quality assessment in genetic services are emerging. These efforts are well developed for molecular and cytogenetic testing and laboratories, and newborn screening programs, but assessing quality in clinical services has lagged, perhaps owing to the small work force and the recent evolution from a few large training programs to multiple training sites. We surveyed the English language, peer-reviewed literature to summarize the knowledge-base of quality assessment of genetics services, organized into the tripartite categories of the Donabedian model of "structure," "process," and "outcome." MEDLINE searches from 1990 to July 2008, yielded 2,143 articles that addressed both "medical/genetic screening and counseling" and "quality indicators, control, and assurance." Of the 2,143 titles, 131 articles were extracted for in-depth analysis, and 55 were included in this review. Twenty-nine articles focused on structure, 19 on process, and seven on outcomes. Our review underscored the urgent need for a coherent model that will provide health care organizations with tools to assess, report, monitor, and improve quality. The structure, process, and outcomes domains that make up the quality framework provide a comprehensive lens through which to examine quality in medical genetics. © 2009 Wiley-Liss, Inc. [source]
