  3. Quality assurance programme for screen film mammography

    International Nuclear Information System (INIS)

    2009-01-01

    The application of radiation in human health, for both the diagnosis and treatment of disease, is an important component of the work of the IAEA. In the area of diagnostic radiology, this work is focused on quality assurance methods to both the promotion of the effective use of radiation for diagnostic outcome, through achieving and maintaining appropriate image quality, and also on dose determination to allow the monitoring and reduction of dose to the patient. In response to heightened awareness of the importance of patient dose contributed by radiology procedures, the IAEA published Dosimetry in Diagnostic Radiology: An International Code of Practice (Technical Reports Series No. 457) in 2007, to form a basis for patient dose determination for the Member States. Further to this, it is recognized that for complex diagnostic procedures, such as mammography, a detailed guidance document is required to give the professionals in the clinical centre the knowledge necessary to assess the patient dose, as well as to ensure that the procedure gives the maximal patient benefit possible. It is well documented that without the implementation of a quality culture and a systematic quality assurance programme with appropriate education, the detection of breast cancer cannot be made at an early enough stage to allow effective curative treatment to be undertaken. Currently there are a number of established quality assurance protocols in mammography from national and regional institutions, however, many of these protocols are distinctive and so a harmonized approach is required. This will allow the Member States to facilitate quality assurance in mammography in a standardized way which will also facilitate the introduction of national quality assurance programmes that are needed to underpin effective population screening programmes for breast cancer. Development of a quality assurance document for screen film mammography was started in 2005 with the appointment of a drafting

    Baldwin, Tamara D.; Hicks, Timothy W.

    2009-06-01

    SKB is preparing a license application for the construction of a final repository for spent nuclear fuel in Sweden. This application will be supported by the safety assessment SR-Site for the post-closure phase. The assessment of long-term safety is based on a broad range of experimental results from laboratory scale, intermediate scale and up to full scale experiments. It is essential that there is a satisfactory level of assurance that experiments have been carried of with sufficient quality, so that results can be considered to be reliable within the context of their use in safety assessment. SSM has initiated a series of reviews of SKB's methods of quality assurance and their implementation. This project includes reviews of the quality assurance (QA) procedures and instructions that have been prepared for the SR-Site assessment as well as reviews of QA implementation at the canister and buffer/backfill laboratories in Oskarshamn, Sweden. The purpose of this project is to assess SKB's quality assurance with the view of providing a good basis for subsequent quality reviews in the context of future licensing. This has been achieved by examination of a number of SKB experiments using a check list, visits to the relevant facilities, and meetings with contractors and a few members of the SKB staff. Overall, the reviewed set of QA documents and instructions do provide reasonably comprehensive coverage of quality-affecting issues relating to the SR-Site safety assessment and, if implemented correctly, will generate confidence in the reliability of the safety assessment results. The results show that the efforts involving quality assurance are increasing within the SKB programme and in general appear to be satisfactory for ongoing experiments and measurements. However, progress in development of the QA documents and instructions has been relatively recent and it may be difficult for these to be fully implemented in the short period remaining before the planned licence

    1984-01-01

    The objective of this Manual is to provide guidance and illustrative examples of the methodology and techniques of internal and external audits that are consistent with the requirements and recommendations of the Code and the Safety Guide. The methodology and techniques are based on the practices of Member States having considerable experience in auditing QA programmes. This Manual is directed primarily towards QA programme auditors and managers and presents methods and techniques considered appropriate for the preparation and performance of audits and the evaluation of results. Its scope includes the techniques and methods used to carry out QA programme audits variously described as 'System', 'Product' and 'Process' audits. The techniques and methods described here may be used as one approach to the evaluation of suppliers' QA capabilities as defined in 50-SG-QA10. Although the Manual is primarily directed towards purchasers and suppliers, it is also relevant to regulatory organizations, such as government offices responsible for quality assurance, which carry out external audits independent of purchasers and suppliers. In such cases similar methods, procedures and techniques may be used

    One hundred years after the discovery of X-rays, they continue being nowadays part of physicians' daily activities, and the diagnosis through the use of X-ray equipment is one of the most important fields in clinical medicine, thus becoming the most important cause of human exposure to artificial sources. For this reason, in the last twenty years, most of the developed countries did the utmost to establish programs which could warrant the quality of the radiographic image. Aiming the protection of human being against the harmful effects of ionizing radiations, in December 1980, World Health Organization decided to form a group of professionals highly experienced in medical radiology, and initiate an inspection and quality control program. In September 1988, the Group of Studies of the Program Related to Radiological Protection of the Commission in the European Communities, prepared a working paper in which guidelines were set up regarding quality of images, dosage to patient, and associated radiographic factors, necessary to obtain acceptable radiologic performance. In Brazil, efforts driven in this direction, guided by some equipment testing, starting in 1990, began to be more known. When the Director and the Head of Radiology in the Military Police Hospital of the State of Rio de Janeiro (HPM) reamed about these efforts, they decided to contact the Institute for Radioprotection and Dosimetry (IRD) of Comissao Nacional de Energia Nuclear and submit the problem of low radiologic performance and increasing rates of rejection. Thus, with the coincidence of interests and needs, along with a proposal from the Commission of the European Communities (CEC), IRD decided to offer the author laboratory support to elaborate a Quality Assurance Program (QAP) to be implemented in HPM.

    A co-ordinated research program (CRP) for optimisation of image quality in mammography in some Eastern European countries has been initiated by IAEA between 1999 and 2001 and the Slovak Republic took part in this program. The aim of this program was to implement the European QA/QC protocol in a sample of mammography departments and to achieve improvement of the image quality and patient dose reduction. On the national level 28 mammography units were chosen in accordance with equipment performance for quality control programme at this departments, for the first part of the mammography audit in the years 2002-2004. Realisation of CRP project contains: 1) Collection and evaluation of clinical images in agreement with EC criteria; 2) Evaluation of the image quality using mammography test phantom; 3) Measurements of the ESD at patients using TLD; 4) Intercomparison of TLD system calibration with IAEA laboratory; 5) Film reject analysis; 6) Implementation of QC program to the mammography units. The measurements of ESD on patients were performed with TLD (LiF 700 Harshaw). In the 6 month period were collected the results of measurements of: 1) object thickness compensation (measured weekly); 2) long time reproducibility (measured daily); 3) phantom image quality on the standard RMI 156 phantom (measured weekly); 4) ESD on phantom with TLD (once during the audit). Automatic Exposure Control compensation for the object thickness variation was measured by exposing different PMMA plates of thickness ranging from 20 to 60 mm, using the clinical settings. The long term reproducibility has been assessed from the measurements of the optical density and mAs product resulted from the exposure on the PMMA plates. In order to estimate the quality of the images the RMI 156 mammography accreditation phantom was chosen. The accreditation phantom contains test objects which simulate small structures seen in the breast (microcalcifications, fibrils, and tumor like masses). Results of

    1978-01-01

    Whilst the need to produce and maintain documentation covering the supply and operation of Nuclear Steam Supply Systems is appreciated, it is felt that there is now a tendency to regard such documentation as more important than the plant itself. This tendency must be corrected if the safety and reliability of nuclear plants is to be maintained. The following paper proposes actions which will bring documentation into its proper perspective and make it more easily understood internationally. In addition, it is proposed that a common international Quality Assurance Programme Standard should be adopted by countries importing and exporting NSSS in order to make the requirements more understandable to all concerned. The proposals cover Quality Assurance Systems Specifications and the training of quality engineers and evaluators, and discuss Quality Assurance Programmes and Quality Plans. Specifically, the paper suggests the actions which could be undertaken now and proposes the bodies which should be responsible for such actions. (author)

  14. Regulatory inspection of the implementation of quality assurance programmes

    International Nuclear Information System (INIS)

    1989-01-01

    This Manual provides guidance to Member States in the organization and performance of their regulatory inspection functions regarding the implementation of nuclear power plant quality assurance programmes. It addresses the interface between, and is consistent with, the IAEA Nuclear Safety Standards (NUSS programme) documents on quality assurance and governmental organization. The Manual offers a practical model and examples for performing regulatory inspections to ensure that the quality assurance programme is operating satisfactorily in the siting, design, manufacturing, construction, commissioning, operation and decommissioning of nuclear power plants. The primary objective is to confirm that the licensee has the capability to manage and control the effective performance of all quality assurance responsibilities during all phases of a nuclear power project. The guidance provided through this Manual for proper establishment and execution of the regulatory inspections helps to enforce the effective implementation of the quality assurance programme as a management control system that the nuclear industry should establish and use in attaining the safety and reliability objectives for nuclear installations. This enforcement action by national regulatory bodies and the emphasis on the purposes and advantages of quality assurance as an important management tool integrated within the total project task have been recommended by the IAEA International Nuclear Safety Advisory Group (INSAG). The primary intended users of this Manual are the management personnel and high level staff from regulatory bodies but it will also be helpful to management personnel from nuclear utilities and vendors. They all are inevitable partners in a nuclear power project and this document offers all of them valuable information on the better accomplishment of quality assurance activities to ensure the common objective of safe and reliable nuclear power production

    1988-01-01

    The fundamental principle of the system of quality assurance in Czechoslovak nuclear power is quality assurance at all stages of the construction and operation of nuclear power plants and the grading fo measures taken, this in dependence on the impact on nuclear safety of the respective nuclear installation or its part. The system has been made fully operational during the construction of nuclear power plants in Temelin and Mochovce. State surveillance is executed by the Czechoslovak Atomic Energy Commission, and the Czech and Slovak Offices for Work Safety. Briefly discussed are the tasks of the building subcontractor of the Temelin nuclear power plant with regard to the programme of quality assurance as well as the results of the solution of the respective research tasks. The programme of quality assurance classifies the selected sections of the structure of a nuclear power plant into three safety categories. No part of the structure is classified into the first category, the second category includes, e.g., the reactor building, cooling tanks and diesel generator units, the third includes the reactor building and the building of auxiliary workshops. Attention is also paid to the problems of the qualification of personnel and to inspection activity. (Z.M.). 12 refs

    A quality assurance programme at the National Calibration Laboratory for ionizing radiation in Tanzania is described. The programme focuses mainly on regular stability check source and reference output measurements, performance testing of TLD systems as well as some external audit checks. It is found that the stability check source measurements are within ± 1%. Similarly, the air kerma rate measurements agree well with calibration uncertainties, that is ± 2% for protection level measurements and ± 1.5% for clinical dosimetry. The results of comparison of dose measurements done on site and those obtained from some external audit checks are also within requirements. This shows that the working standards have been kept with good care, and that the traceability to the international measurement system is adequately maintained. Some examples on calibration transfer activities are briefly discussed

    The main efforts of Nuclear Regulatory Authority of the Slovak Republic (NRA SR) was focused on support of quality assurance programmes development at responsible organizations Bohunice V-1 and V-v and Mochovce NPPs and their inspection. Development of the level two documentation of a partial quality assurance programme for NPP operation continued at Mochovce NPP. Most of documentation has been submitted to NRA SR for comments and approval. NRA SR invited a mission of French experts to Mochovce NPP to review preparation and performance of internal audits that would be beneficial for improvement in this kind activities at the NPP. Bohunice NPP continued in development of a partial quality assurance programme for operation. The Quality Assurance Programme submitted to NRA SR for approval. Based on a request of Bohunice NPPs, NRA SR consulted the draft quality assurance programme developed by Siemens for stage of the 'Basic Design' of V-1 NPP upgrading. The programme had not been submitted for approval to NRA SR prior to completion of works by Siemens. Based on an internal audit that had been performed, corrective measures were proposed to meet requirements on review and approval of suppliers quality assurance programmes. Requirements related to the quality assurance at nuclear installations were prepared to be incorporated into principles of a act on peaceful use of nuclear power in Slovak Republic

  1. A framework for a quality assurance programme for PSA

    International Nuclear Information System (INIS)

    1999-08-01

    Reviews organized by the IAEA of probabilistic safety assessments (PSAs) of nuclear facilities have, in the past years, shown significant progress in the technical methods and data used for these studies. The IAEA has made a considerable effort to support the development of technical capabilities for PSA in Member States and in writing technical procedures for carrying out PSAs. However, the reviews have also shown significant deficiencies in quality assurance (QA) for PSAs, ranging from no QA at all to inappropriate, inefficient or unbalanced QA. As a PSA represents a very complex model which describes the risk associated with a nuclear facility, an appropriate and efficient QA programme is crucial to obtain a quality PSA. Historically, in the first integral PSAs, many of the PSA elements were handled by independent groups. These elements were finally integrated and put together in the overall model. Many of the interfaces between the elements or tasks were handled as appropriate by exchanging information in oral or written form. Since WASH-1400, the first integral PSA, the process of constructing the PSA model has been further developed. PSA elements previously considered separately can now be handled together with the capable software developed in recent years. Software has made interface control and data transfer easier to perform, but also permits the development of more detailed and complex models. Previously, QA for PSA projects was organized in an ad hoc manner and was sometimes very limited. In recent years, increasingly comprehensive QA programmes have been developed and implemented for PSA projects. Today, a comprehensive, effective and performance-oriented QA is considered to be essential for a reliable and credible PSA. This report describes the framework for developing an adequate QA programme for PSA studies. The framework is based on and is in accordance with the related QA guidelines of the IAEA for safety in nuclear power plants and other nuclear

    2018-04-02

    Derbyshire Community Health Services (DCHS) NHS Foundation Trust provides a wide range of community-based health services. After the Care Quality Commission (CQC) found gaps in the trust's assurance process, its board decided to develop a method of continuous quality improvements that could be used as a basis for the trust's quality assurance system. The trust adapted and built on an acute model so it was suitable for community services. The final assurance system, Quality Always, has four elements: the clinical assessment and accreditation scheme; leadership development; 'champions' within clinical teams to support and promote the scheme; and dashboards to record and monitor progress. A system to recognise and reward achievement was essential for success. Quality Always has resulted in better care quality, an improved CQC rating, a sense of achievement among staff, the development of support networks, learning (especially among support staff) and good practice being shared.

    1976-01-01

    The Exxon Nuclear quality assurance programme for the design and fabrication of reload fuel for light-water reactors is described. The programme is based on the 18 quality assurance criteria used for the design and construction of nuclear facilities in the United States of America, but is broadened considerably to reflect other inputs and experiences unique to nuclear fuel production. The government and utility interfaces with the fuel supplier in the area of quality assurance, and future trends, for example, the development of topical quality assurance reports, are also discussed. Quality assurance is discussed in terms of three fundamental categories: management control, engineering assurance and quality control. Examples of specific design, processing and inspection considerations which relate to known fuel failure mechanisms are discussed. The results of irradiated fuel examinations to date have shown that certain fuel failure mechanisms can be alleviated by the considerations described and that fuel of the requisite quality can be consistently produced.

    Our aim was to retrospectively evaluate the results of all audits performed in the past and to assess their value in the quality assurance of the Dutch breast cancer screening programme. The audit team of the Dutch Reference Centre for Screening (LRCB) conducts triennial audits of all 17 reading units. During audits, screening outcomes like recall rates and detection rates are assessed and a radiological review is performed. This study investigates and compares the results of four audit series: 1996-2000, 2001-2005, 2003-2007 and 2010-2013. The analysis shows increased recall rates (from 0.66%, 1.07%, 1.22% to 1.58%), increased detection rates (from 3.3, 4.5, 4.8 to 5.4 per 1000) and increased sensitivity (from 64.5%, 68.7%, 70.5% to 71.6%), over the four audit series. The percentage of 'missed cancers' among interval cancers and advanced screen-detected cancers did not change (p = 0.4). Our audits not only provide an opportunity for assessing screening outcomes, but also provide moments of self-reflection with peers. For radiologists, an accurate understanding of their performance is essential to identify points of improvement. We therefore recommend a radiological review of screening examinations and immediate feedback as part of an audit. • Radiological review and immediate feedback are recommended as part of an audit. • For breast screening radiologists, audits provide moments of self-reflection with peers. • Radiological review of screening examinations provides insights in recall behaviour. • Accurate understanding of radiologists' performance is essential to identify points of improvement.

    The importance of quality assurance in radiation therapy, as well as its positive consequences on patient treatment outcome, is well known to radiation therapy professionals. In low- and middle-income countries, the implementation of quality assurance in radiation therapy is especially challenging, due to a lack of staff training, a lack of national guidelines, a lack of quality assurance equipment and high patient daily throughput. According to the International Atomic Energy Agency (IAEA) Directory of Radiotherapy Centres, the proportion of linear accelerators compared with Co-60 machines has increased significantly in recent years in low- and middle-income countries. However, this increase in the proportion of relatively more demanding technology is not always accompanied with the necessary investment in staff training and quality assurance. The IAEA provides supports to low- and middle-income countries to develop and strengthen quality assurance programmes at institutional and national level. It also provides guidance, through its publications, on quality assurance and supports implementation of comprehensive clinical audits to identify gaps and makes recommendations for quality improvement in radiation therapy. The new AAPM TG100 report suggests a new approach to quality management in radiation therapy. If implemented, it will lead to improved cost-effectiveness of radiation therapy in all income settings. Low- and middle-income countries could greatly benefit from this new approach as it will help direct their scarce resources to areas where they can produce the optimum impact on patient care, without compromising patient safety.

    1993-01-01

    Penetrating radiations such as x-rays, gamma rays, neutrons are extensively used for radiographic inspection of various components used in space programmes. Some of these are rocket motor segments, assembled motors, composite nozzles, igniters, pyro devices, and various critical sub systems. These components employ advanced materials like composites, propellants, insulation materials, alloy steels, maraging steel, pyro techniques etc. Often they are in complex geometrical shapes and assemblies. Simulation of radiation environment on a number of components used in satellites is also carried out using radiation sources. This will help in assessing the effect of terrestrial radiation on the components that work in space. Future trends in the exploitation of radiation for space applications include automated radiography and development of expert systems, computed tomography, improvement in realtime radiography, Compton back scatter tomography etc. Adapting some of the advancements in medical radiology to industrial environment is also a welcome step in future.

    2004-02-01

    In cooperation with the Hochrhein-Institute for Research in Rehabilitation (HRI), the Association for Assuring the Quality of Education in Physiotherapy Schools in Germany (ISQ) has developed a quality assurance programme for physiotherapy schools. It aims at assessing the quality of physiotherapy schools in Germany, and to award a quality seal based on compliance with defined criteria. First, a catalogue of quality features and criteria relevant for education in physiotherapy was developed. It is based on the analysis of questionnaires that had been sent to all German physiotherapy schools, to selected physiotherapists and leading physiotherapists in hospitals, to competent federal authorities, and to three school-classes with group discussions. The persons addressed named 360 different quality features. They were collected in a catalogue, revised in a multi-stage Delphi procedure, and approved consensually. The final criteria were transformed into basic quality requirements, and formulated as a check-list. Assessment of the quality features is carried out by trained visitors. In addition, the satisfaction of students is assessed with a questionnaire. The results of the interviews and the questionnaires are fed back to the schools in a quality report. Schools meeting all basic quality requirements are awarded the seal of quality. The seal is valid for three years. Since January 2003, this procedure is available for all schools in Germany. Until September 2002, a pretest of visitations and student questionnaires had been carried out with 31 member schools of the ISQ; according to the resulting quality reports, none of these schools would instantly be awarded the quality seal. In all, more than half of the schools do not meet 10 of the 42 basic criteria. Fundamental deficiencies have been found in the documentation pertaining to supervision of practical training. In terms of training, further training and professional development of their teachers and associated

    Aims and method This paper intends to analyse the number of applications, trainee demographic and approval rate of those applying for out of programme training (OOPT) or out of programme research (OOPR) between January 2008 and April 2013 using the committee’s anonymised database. We also describe the process of application and approval by the Quality Assurance Committee. Results There were 90 applications, including 10 resubmissions during the 64-month period. Most applicants (77%) were higher trainees; 53% of applicants were from the London deanery; 60% of applications were for research posts and higher degrees (OOPR). Overall, 64% were approved by the committee: 70% for OOPRs and 53% for OOPTs. Clinical implications This paper shows with transparency the breakdown of applications to the Quality Assurance Committee. Around two-thirds of applications to the committee are supported (64%). Relatively few psychiatry trainees (2.5%) have applied for an OOPT or an OOPR over the past 5 years. PMID:26191450

    The transition to a fully digital breast screening programme, utilising three different full-field digital mammography (FFDM) systems has presented many challenges to the implementation of the European guidelines for physico-technical quality assurance (QA) testing. An analysis of the QA results collected from the FFDM systems in the screening programme over a 2-y period indicates that the three different systems have similar QA performances. Generally, the same tests were failed by all systems and failure rates were low. The findings provide some assurance that the QA guidelines are being correctly implemented. They also suggest that there is more scope for the development of the relevance of the guidelines with respect to modern FFDM systems. This study has also shown that a summary review of the QA data can be achieved by simple organisation of the QA data storage and by automation of data query and retrieval using commonly available software.

  19. Dose reduction in mammography as a consequence of quality assurance programme

    International Nuclear Information System (INIS)

    Staniszewska, M. A.; Jankowski, J.

    2003-01-01

    Mammography became one of more frequent radiological examinations in the most of European countries. This is accepted as a sensitive method for detection of early breast cancers. On the other hand, this is the special imaging technique, where reliability of result is strongly influenced by technical conditions. Hence, the exposure parameters should have been chosen in dependence on image recording system. In opposite, an informative quality of the produced image is not sufficient for a true clinical diagnosis. Thus, optimisation of the practice is not achieved and a benefit for patient is none. Implementation of Quality Assurance programme can prevent the situation: systematic quality control of mammographic x-ray units allows finding the technical and methodological incorrectness. If these findings are followed by the appropriate remedial actions, the main aim will be achieved, i.e. good quality of image with reasonable low doses to patients. This approach was verified on 15 mammographic units in Lodz, covered by full cycle of quality control programme. Doses were measured during CC projection for over 100 patients. Quality of image was evaluated for RMI 156 accreditation phantom as a standard object. The main technical incorrectness was found for automatic exposure control system, and especially for compensation of object thickness. The available remedial actions allowed reducing the doses to patients by 21% (on average). Additionally, after the remedial action quality of phantom image was found better for 3 facilities where primary had been below the acceptance level. The main points of Quality Assurance programme are available for most of x-ray diagnostic facilities and should have been obligatory. (authors)

    To develop and evaluate an image grading external quality assurance system for the Scottish Diabetic Retinopathy Screening Programme. A web-based image grading system was developed which closely matches the current Scottish national screening software. Two rounds of external quality assurance were run in autumn 2008 and spring 2010, each time using the same 100 images. Graders were compared with a consensus standard derived from the top-level graders' results. After the first round, the centre lead clinicians and top-level graders reviewed the results and drew up guidance notes for the second round. Grader sensitivities ranged from 60.0 to 100% (median 92.5%) in 2008, and from 62.5 to 100% (median 92.5%) in 2010. Specificities ranged from 34.0 to 98.0% (median 86%) in 2008, and 54.0 to 100% (median 88%) in 2010. There was no difference in sensitivity between grader levels, but first-level graders had a significantly lower specificity than level-two and level-three graders. In 2008, one centre had a lower sensitivity but higher specificity than the majority of centres. Following the feedback from the first round, overall agreement improved in 2010 and there were no longer any significant differences between centres. A useful educational tool has been developed for image grading external quality assurance. © 2011 The Authors. Diabetic Medicine © 2011 Diabetes UK.

    Within the frame of the tasks developed by the Argentine-Brazilian Contractors Coordination Committee in the nuclear area, which was at the beginning promoted by the Contractor Committee of the Argentine Association of Nuclear Technology, a working team was created between both countries in order to analyze the existing regulations and the Quality Assurance systems applied in Brazil and Argentina for their nuclear projects. This paper describes the steps to be followed so as to fulfill the compatibility of the rules, quality assurance and firm certification, laboratories, personnel and materials, and the applicable quality assurance programmes. At first, the methodology applied was the collection of the information and the existing regulations in each one of the countries, to exchange them, analyze them and arrange joint meetings and organize a seminar with experts from both countries to develop and discuss the objectives of this working team. As a result of these activities, the criteria adopted will allow, together with another actions, that both Argentine and Brazilian firms make exchanges and integrations in the nuclear field to supply Atucha II and Angra II.

  7. Lot quality assurance sampling for monitoring immunization programmes: cost-efficient or quick and dirty?

    Science.gov (United States)

    Sandiford, P

    1993-09-01

    In recent years Lot quality assurance sampling (LQAS), a method derived from production-line industry, has been advocated as an efficient means to evaluate the coverage rates achieved by child immunization programmes. This paper examines the assumptions on which LQAS is based and the effect that these assumptions have on its utility as a management tool. It shows that the attractively low sample sizes used in LQAS are achieved at the expense of specificity unless unrealistic assumptions are made about the distribution of coverage rates amongst the immunization programmes to which the method is applied. Although it is a very sensitive test and its negative predictive value is probably high in most settings, its specificity and positive predictive value are likely to be low. The implications of these strengths and weaknesses with regard to management decision-making are discussed.

    Nuclear fuel for Research Reactors and Pressurised Heavy Water Reactors (PHWRs) is being fabricated in India for a period of over two decades. The fuel is produced to conform to stringent quality control specifications. Generally, the performance of the fuel has been very good in the reactors. This is not only due to the high quality workmanship in the various stages of production but also to the meticulous care exercised in the planning and application of quality control and quality assurance procedures. For the nuclear fuel used in Water Reactors, extensive material specifications have been compiled and they are periodically reviewed and revised. The specifications cover various aspects such as metallurgical and mechanical properties, non-destructive testing, dimensional and visual standard requirements. Similarly, detailed manufacturing engineering instructions (MEIs) and quality control instructions (QCIs) have been drawn. For any deviations from the specified requirements, design concession committee considers all deviations and acceptance or rejection criteria are evolved. In this task, the design concession committee is supported by experimentation in various laboratories of the Department of Atomic Energy. The Quality Assurance procedures have been evolved over a long period of time. They generally conform to the latest code and recommended guides of IAEA regarding Quality Assurance in the manufacture of fuel. (orig.)

    For many years the International Atomic Energy Agency (IAEA) has been promoting analytical quality assurance and quality control in its Member States with emphasis on measurands that are amenable to analysis by nuclear and related techniques, i.e. radionuclides, trace elements, and stable isotopes. This paper reviews briefly the rationale for some of these activities, particularly in relation to the needs of participants in developing countries arising out of co-ordinated research programmes, technical co-operation projects and global and regional networks. Emphasis is given to biological and environmental reference materials with a matrix of natural origin. Also described are some activities arising out of the requirements of ISO-25 and other relevant international quality standards. (orig.)

  10. Development of a quality assurance programme for SSDLs: report of the first research coordination meeting

    International Nuclear Information System (INIS)

    1998-01-01

    The optimum outcome of treatment in radiotherapy requires high accuracy of dosimetry, which imposes the need of accurate calibrations and measurements by the SSDLs. This can only be achieved through quality assurance systems which cover quality control of standards, calibration equipment and calibration procedures, and which introduces external audits for the operation. The SSDL Scientific Committee as well as a Consultants' meeting have suggested the development of such Quality Systems (QS) at the SSDLs within a Coordinated Research Project (CRP). At this first Research Coordination Meeting (RCM), the status of efforts made by the participating laboratories to achieve the goals of the CRP were reviewed. The outline for the joint study in order to develop guidance for quality systems was established, and the work assignments defined. It was agreed that the final aim would be to prepare a suitable document, for the Agency, to provide guidance for the SSDLs to develop their own QS and to prepare appropriate Quality Manuals. This guidance shall be based on the general quality criteria in accordance with ISO/IEC guide 25 while also adopting the Criteria of the SSDLs and the practical recommendations on calibration procedures issued by the IAEA. To provide experience and confidence in the methods for the preparation of the guidelines, a Quality Manual of each participating laboratory will be prepared during the three years of the CRP. Trial programmes for the whole duration of the CRP on internal quality control testing as well as external quality audits of the participating SSDLs were also established. (author)

    During the last ten years the capacity of local production of radiopharmaceuticals in each country of the latinoamerican region has been increased because of a coordinated, joint action among them. This is a consequence of the implementation of the ARCAL XV Project ''Production and Quality Control of radiopharmaceuticals''. During this period attention has been focussed in the development of more defined agents for specific functional investigations such as the second generation 99m Tc radiopharmaceuticals. Active research is also being continued to develop third generation radiopharmaceuticals based upon monoclonal and policlonal antibodies, peptides and other biomolecules. Group training in this field is also being carried out in this region. The enhancement of quality requirements and the globalization of the economy make it necessary to produce same quality radiopharmaceuticals and the harmonisation of the legislation and regulatory needs should be raised in a next future. The implementation of a quality assurance programme in each country of the latinoamerican region and the harmonisation of those programmes will be the principal goal of this project. (author)

    The main common difficulties are presented found in the implementation of effective Quality Management and Quality Assurance Programmes, based on the recommendations of the IAEA International Nuclear Safety Advisory Group, the information collected by the IAEA experts participating in its meetings, and the results of the IAEA Operational Safety Review Team missions. The difficulties were identified in several areas. The most relevant root causes can be characterized as lack of understanding of quality principles and difficulty in implementation by the responsible management. The IAEA programme is described attempting to provide advice and support in the implementation of an effective quality programme through a number of activities including: preparation of practical guidelines, training programmes for management personnel, assistance in building up qualified manpower, and promoting the quest for excellence through the exchange of experience in the implementation of effective Quality Management and Quality Assurance Programmes in nuclear power plants with good performance records.

    Lack, Nicholas; Gerhardinger, Ursula

    2010-01-01

    Judging the effectiveness of external quality assurance programmes by comparing current performance with unadjusted regional or national crude averages is misleading because the influence of the actual size of the populations under consideration as well as the variance of performance between hospitals is underestimated. Not only do these artefacts lead to a general overestimation of changes in regional averages. They also may lead to a ranking confounded by regional size. An assessment at unit level circumvents these difficulties. The differential grading of degree of departure of a unit's performance from national targets available from funnel plots allows, in addition, for the discrimination between effects due to the monitoring institution and achievements attributable to the hospital under surveillance. A central role is played by the scoring system adopted for evaluating incremental changes of performance indicator values in successive years. The following proposal is intended to both assist the assessment of effectiveness of quality assurance programmes and identify areas requiring urgent improvement. Bavarian quality assurance data (BAQ 1995) are used to illustrate the method. Copyright © 2010. Published by Elsevier GmbH.

    1989-01-01

    Regulations made under the Healing Arts Radiation Protection (HARP) Act, Government of Ontario, Canada, were promulgated in the form of a safety Code in November, 1985. These regulations require a minimum technical quality assurance (QA) programme for all diagnostic radiology facilities in the Province. The mandatory QA programme requires certain tests and procedures to be carried out at specified intervals. The tests include photographic quality control, patient entrance exposure measurement, collimation, half-value layer, phototiming parameters, fluoroscopic parameters including maximum patient entrance exposure rate, resolution, limit timer and automatic brightness control, and tomographic parameters including fulcrum accuracy, thickness of cut and mechanical stability. Records of the results of these tests must be kept for at least 6 years. A set of HARP guidelines published in June 1987 includes a description of appropriate measuring methods for each test together with a set of forms for recording the results of such tests. The regulations specify limiting values for a number of equipment performance parameters, including the maximum allowable patient skin entrance exposure values for common radiographic projections.

  17. Contaminant monitoring programmes using marine organisms: Quality assurance and good laboratory practice

    International Nuclear Information System (INIS)

    1990-01-01

    This publication provides guidelines for obtaining reliable and relevant data during monitoring programmes in which contaminants are measured in marine organisms. It describes the precautions to be taken in each of the procedural steps from planning and sampling to the publication of data reports. The purpose of this document is to provide general guidance on quality assurance and to outline the approach that could be taken by laboratories to achieve the specific aims(s) for each marine pollution monitoring programme. Since most laboratories are currently focussing on programmes involving marine organisms, this document will be confined to this aspect. Four main aims can be identified for programmes involving the collection and analysis of marine organisms for the three main groups of contaminants (metals, organochlorine compounds and petroleum hydrocarbons), these are: (i) The measurement of contaminant levels in edible marine organisms in relation to public health; (ii) The identification of heavily contaminated areas of the sea (''hot spots'') where levels of contaminants are at least an order of magnitude higher than levels in clean or uncontaminated areas; (iii) The establishment of present levels of contaminants in marine organisms (i.e., a ''baseline''); (iv) The assessment of changes in concentrations of contaminants in organisms over a period of time (trends). The selection of organisms will be dictated by the eating patterns of the population. These can be identified by a survey of the species sold at the market, by obtaining information from colleagues in government departments who deal with such matters or in the absence of such information, by distributing a questionnaire to a representative section of the general public. 9 refs, 4 figs

    There is a need for evaluation of screening and grading services for diabetic retinopathy (DR) in compliance with quality-assurance (QA) standards. We describe the screening/grading QA programme set up for OPHDIAT over the 2005-2006 period. Screening and grading objectives, evaluation criteria and minimum acceptable QA standards were set. To ensure the quality of DR photos, the proportion of nongradable photos in at least one eye had to be less than 10%. To ensure grading accuracy, intergrading agreement had to be greater than 90%. Grader-generated reports had to be available in less than 48 h for more than 80% photos. Readers had to grade 500 to 3000 photos per year. Sixteen screening centres were opened between June 2004 and December 2006, and 14,769 patients were screened. Percentages of nongradable photos were consistently below the QA requirement (less than 10%). Overall, 800 photos were graded a second time by a reader blinded to original grading; agreement between graders ranged from 92 to 99%. More than 90% of grader-generated reports were produced within 48 h. The number of readings by each grader nearly achieved the QA standard. QA for DR telescreening should be a continuous process to provide performance feedback, thus guaranteeing a high standard for delivered results. Almost all of the predetermined QA standards in OPHDIAT for screening and grading were met. Besides the quality/sensitivity of the screening/grading modalities, it is important to evaluate at-risk patients so that they can be treated efficiently; this should be addressed in a global QA programme.

    A commercially available motion phantom (QUASAR, Modus Medical) was modified for programmable motion control with the aim of reproducing patient respiratory motion in one dimension in both the anterior–posterior and superior–inferior directions, as well as, providing controllable breath-hold and sinusoidal patterns for the testing of radiotherapy gating systems. In order to simulate realistic patient motion, the DC motor was replaced by a stepper motor. A separate 'chest-wall' motion platform was also designed to accommodate a variety of surrogate marker systems. The platform employs a second stepper motor that allows for the decoupling of the chest-wall and insert motion. The platform's accuracy was tested by replicating patient traces recorded with the Varian real-time position management (RPM) system and comparing the motion platform's recorded motion trace with the original patient data. Six lung cancer patient traces recorded with the RPM system were uploaded to the motion platform's in-house control software and subsequently replicated through the phantom motion platform. The phantom's motion profile was recorded with the RPM system and compared to the original patient data. Sinusoidal and breath-hold patterns were simulated with the motion platform and recorded with the RPM system to verify the systems potential for routine quality assurance of commercial radiotherapy gating systems. There was good correlation between replicated and actual patient data (P 0.003). Mean differences between the location of maxima in replicated and patient data-sets for six patients amounted to 0.034 cm with the corresponding minima mean equal to 0.010 cm. The upgraded motion phantom was found to replicate patient motion accurately as well as provide useful test patterns to aid in the quality assurance of motion management methods and technologies.

  2. Guidelines for the introduction of a quality assurance programme in a diagnostic imaging department

    International Nuclear Information System (INIS)

    1992-01-01

    Radiographers, whether they practice in the National Health Service (NHS) or other health care systems, always strive to deliver a high quality service for their patients. The profession and its members work hard to maintain and improve standards of patient care and technical accuracy. Why then does the College of Radiographers feel it necessary to publish Quality Assurance Guidelines? The answer lies in the greater awareness that the best possible service provision requires every part of the whole service to be performing as well as it possibly can. To be sure these individual parts are achieving this goal requires that we set standards for them and monitor and reassess them regularly. The quality of an individual's or a system's performance cannot be defined in absolute terms, although this is how many people would see it. There are too many variables, some of which cannot be controlled. Instead, we must define quality as the ability to perform the required task to set standards, given the prevailing conditions and existing resources. In radiography we can assure quality by being sure that those factors over which we have control are optimised. The College of Radiographers Working Party on Quality Assurance was formed in response to members' concerns about the requirements of professionalism and legislation with regard to quality assurance. Members were confused by the approach to quality management issues, standard setting, monitoring, evaluation and the required record keeping. Work began on a comprehensive publication centred on the quality assurance of radiographic processes. However, the College felt there was danger in following a well trodden path, particularly as the passing months saw the release of a series of related publications from various sources pre-emptying the efforts of the Working Party. Ultimately, the original remit was considered to hold greater promise - a set of guidelines for the quality management of the whole of our service delivery

    The main efforts of Nuclear Regulatory Authority of the Slovak Republic (UJD) have been focused on inspection of quality assurance programmes of Slovak Power Stations, plc. and its daughter companies at Bohunice and Mochovce. Two quality assurance inspections in the area of periodical in service inspections (V-2 units) and tests of selected equipment (NPP V-2 units) and operation control (V-1 units) has been performed at NPPs Bohunice. One violation of decree on quality assurance of selected equipment has been found in the area of documentation archiving. The inspection concerning the implementation of quality assurance programme for operation of NPP Mochovce in the area of operation control has been performed focused on safety aspects of operation, operational procedures, control of operational events and feedback from operational experience. The results of this inspection were positive. Inspection of implementation of quality assurance programme for operation of radioactive waste repository (RU RAW) at the Mochovce location has been performed focused on receiving of containers, with radioactive wastes, containers handling, radiation monitoring, activities of documentation control and radiation protection at the repository site. No serious deficiencies have been found out. Also one inspection of experimental nuclear installations of VUJE Trnava at Jaslovske Bohunice site has been performed focused on procurement control, quality audits, documentation and quality records control when performing activities at experimental nuclear installations. The activity on development of internal quality assurance system continued. The implementation of this system will assure quality and effective fulfilment enlarged tasks of UJD with limited resources for its activity. The analyses of possible use of existing internal administrative control documentation as a basis for future quality system procedures was performed in co-operation with an external specialised organisation.

    In recent years, 'private standards' in animal health and welfare have become increasingly common, and are often incorporated into quality assurance (QA) programmes. Here, we present an overview of the use of private animal health and welfare standards in QA programmes, and propose a generic framework to facilitate critical programme review. Private standards are being developed in direct response to consumer demand for QA, and offer an opportunity for product differentiation and a means to drive consumer choice. Nonetheless, a range of concerns have been raised, relating to the credibility of these standards, their potential as a discriminatory barrier to trade, the multiplicity of private standards that have been developed, the lack of consumer input and compliance costs. There is a need for greater scrutiny of private standards and of associated QA programmes. We propose a framework to clarify the primary programme goal(s) and measureable outputs relevant to animal health and welfare, the primary programme beneficiaries and to determine whether the programme is effective, efficient and transparent. This paper provides a theoretical overview, noting that this framework could be used as a tool directly for programme evaluation, or as a tool to assist with programme development and review.

    International Nuclear Information System (INIS)

    1976-01-01

    Full text: Quality assurance is used extensively in the design, construction and operation of nuclear power plants. This methodology is applied to all activities affecting the quality of a nuclear power plant in order to obtain confidence that an item or a facility will perform satisfactorily in service. Although the achievement of quality is the responsibility of all parties participating in a nuclear power project, establishment and implementation of the quality assurance programme for the whole plant is a main responsibility of the plant owner. For the plant owner, the main concern is to achieve control over the quality of purchased products or services through contractual arrangements with the vendors. In the case of purchase of nuclear fuel, the application of quality assurance might be faced with several difficulties because of the lack of standardization in nuclear fuel and the proprietary information of the fuel manufacturers on fuel design specifications and fuel manufacturing procedures. The problems of quality assurance for purchase of nuclear fuel were discussed in detail during the seminar. Due to the lack of generally acceptable standards, the successful application of the quality assurance concept to the procurement of fuel depends on how much information can be provided by the fuel manufacturer to the utility which is purchasing fuel, and in what form and how early this information can be provided. The extent of information transfer is basically set out in the individual vendor-utility contracts, with some indirect influence from the requirements of regulatory bodies. Any conflict that exists appears to come from utilities which desire more extensive control over the product they are buying. There is a reluctance on the part of vendors to permit close insight of the purchasers into their design and manufacturing procedures, but there nevertheless seems to be an increasing trend towards release of more information to the purchasers. It appears that

    The Individual Monitoring Service (I.M.S.) of the Departamento de Proteccao Radiologica e Seguranca Nuclear (D.P.R.S.N.) at the Instituto Tecnologico e Nuclear (I.T.N.) in Portugal operates a thermoluminescence dosimetry system to monitor approximately 3,000 workers for external radiation exposure on a monthly basis. The workers come from nearly 230 facilities in the medical, research and conventional industry fields of activity and almost 85% of the people monitored in 2005 are from medical facilities. The TLD system in use is based on two Harshaw 6600 automatic readers and on the Harshaw 8814 T.L. card and holder containing two detector elements of LiF:Mg,Ti (TLD-100) for the evaluation of Hp(10) and Hp(0.07). All the workers are monitored on a monthly basis using whole body dosemeters. The I.M.S. has implemented a Quality Assurance and Quality Control (Q.A./Q.C.) programme that covers all the aspects of monitoring, from the monitoring request of a customer to the final issue of a dose report. The main aspects of the Q.A./Q.C. programme implemented at the I.M.S. will be presented in this paper using fluxograms and schemes. Several issues will be addressed, e.g., administrative procedures, technical procedures, dealing with complaints, training of staff, etc. The relationship of the I.M.S. with external entities like the customer, the regulatory authority, the central dose registry, the calibration facility, suppliers, maintenance providers, etc. will be mentioned on the administrative procedures described as well as on the technical procedures where applicable. The main technical procedures will be presented in this paper and references will be made to a TLD Quality Control database internally developed and designed for the storage of important Q.C. parameters like the element correction coefficients, reader calibration factors, electronic quality control data generated on a daily basis, and the study of their evolution with time.

  7. Revitalizing quality assurance

    International Nuclear Information System (INIS)

    Hawkins, F.C.

    1998-01-01

    The image of someone inspecting or auditing often comes to mind when people hear the term quality assurance. Although partially correct, this image is not the complete picture. The person doing the inspecting or auditing is probably part of a traditional quality assurance organization, but that organization is only one aspect of a properly conceived and effectively implemented quality assurance system whose goal is improved facility safety and reliability. This paper introduces the underlying philosophies and basic concepts of the International Atomic Energy Agency's new quality assurance initiative that began in 1991 as part of a broad Agency-wide program to enhance nuclear safety. The first product of that initiative was publication in 1996 of a new Quality Assurance Code 50-C/SG-Q and fourteen related Safety Guides. This new suite of documents provide the technical and philosophical foundation upon which Member States can base their quality assurance programs. (author)

    The elements (principles) of quality assurance can be applied to the operation of the analytical chemistry laboratory to provide an effective tool for indicating the competence of the laboratory and for helping to upgrade competence if necessary. When used, those elements establish the planned and systematic actions necessary to provide adequate confidence in each analytical result reported by the laboratory (the definition of laboratory quality assurance). The elements, as used at the Hanford Engineering Development Laboratory (HEDL), are discussed and they are qualification of analysts, written methods, sample receiving and storage, quality control, audit, and documentation. To establish a laboratory quality assurance program, a laboratory QA program plan is prepared to specify how the elements are to be implemented into laboratory operation. Benefits that can be obtained from using laboratory quality assurance are given. Experience at HEDL has shown that laboratory quality assurance is not a burden, but it is a useful and valuable tool for the analytical chemistry laboratory

    Colling, A.

    2000-01-01

    The external quality assurance programme (EQAP) consists of three equally important items: the questionnaire, the monitoring of the internal quality control data and the external quality control test panel. The EQAP is conducted twice per year. The first round of the EQAP for the FAO/IAEA liquid phase blocking ELISA being used in Southeast Asia was carried out in 1995-1996. A total of 10 laboratories from Asia participated. The round consisted of three FMD sero-types (O, A and Asia) for both, the antigen and antibody ELISA. No interim report was produced, but results were communicated on an individual basis. The second round was initiated in late 1998. Participating laboratories were the same as in 1996. This time the EQA proficiency exercise consisted only of one sero-type (O 1 Manisa) for the FMD Antibody ELISA. The results of this round are presented in this report. All participants replied to this EQA exercise. Out of ten participants six laboratories returned all EQA components (EQC results, IQC data and questionnaire). Four laboratories did not return the complete set of the EQA panel. Three out of five EQC samples achieved an overall agreement of 100%. Two EQC samples were excluded from the evaluation because a minimum of 80% of agreement between participants was not achieved. In comparison to the reference values for the EQC samples as established by the World Reference Center (WRC), UK, the participating laboratories produced lower PI values for the three positive samples 2, 8 and 5 and higher PI values for the negative samples 10 and 9 resulting in a decreased binding ratio. Nevertheless results show that all laboratories are able to detect a strong positive sample and no equivocally result was obtained for the two negative samples. Weak positive sera close to the cut-off are problematical for a minority of the laboratories, which tested these samples negative. The closer the sample comes to the cut-off the less agreement between laboratories is reached

  16. Manual on the selection of appropriate quality assurance programmes for items and services of a nuclear power plant

    International Nuclear Information System (INIS)

    1984-02-01

    This manual provides guidance and illustrative examples for devising a system by which applicable quality assurance activities may be selected and applied to items and services in conformance with the requirements of the Code and the guidance of SG-QA 1. The selective application system described herein contains the following elements: (1) Classification of items and services; (2) Grading of quality assurance activities; (3) Correlation of applicable quality assurance activities with items and services; (4) Adaptation of selected quality assurance activities to the unique needs of the items or services; (5) Specifying of applicable quality assurance activities in bid specifications or in a contract. This selective application system is intended to be used by plant systems designers in the classifying of items (structures, components and materials) and related services; and by the organizations designing, manufacturing, installing and operating items or performing support services for such items in the specifying of applicable quality assurance activities that are to be implemented. The parts of the system should be developed to the degree and sophistication necessary for the particular needs of the project or organization. There are many methods and techniques that may be used effectively and those of one organization may not suit the purposes of another organization. It is important that the methodology of the system is developed with sufficient instructions documented to guide its consistent and disciplined execution

    Metabolomics promises a holistic phenotypic characterization of biological responses to toxicants. This technology is based on advanced chemical analytical tools with reasonable throughput, including mass-spectroscopy and NMR. Quality assurance, however - from experimental design, sample preparation, metabolite identification, to bioinformatics data-mining - is urgently needed to assure both quality of metabolomics data and reproducibility of biological models. In contrast to microarray-based transcriptomics, where consensus on quality assurance and reporting standards has been fostered over the last two decades, quality assurance of metabolomics is only now emerging. Regulatory use in safety sciences, and even proper scientific use of these technologies, demand quality assurance. In an effort to promote this discussion, an expert workshop discussed the quality assurance needs of metabolomics. The goals for this workshop were 1) to consider the challenges associated with metabolomics as an emerging science, with an emphasis on its application in toxicology and 2) to identify the key issues to be addressed in order to establish and implement quality assurance procedures in metabolomics-based toxicology. Consensus has still to be achieved regarding best practices to make sure sound, useful, and relevant information is derived from these new tools.

    Evidence-based clinical guidelines provide standards for the provision of healthcare. However, these guidelines have been poorly implemented in daily practice. Clinical audit is a quality improvement tool to promote quality of care in daily practice and to improve outcomes through the systematic review of care delivery and implementation of changes. A major priority in the management of subjects with cardiovascular disease (CVD) management is secondary prevention by controlling cardiovascular risk factors and providing appropriate medical treatment. Clinical audits can be applied to monitor modifiable risk factors and evaluate quality improvements of CVD management in daily practice. Existing clinical audits have provided an overview of the burden of risk factors in subjects with CVD and reflect real-world risk factor recording and management. However, consistent and representative data from clinic audits are still insufficient to fully monitor quality improvement of CVD management. Data are lacking in particular from low- and middle-income countries, limiting the evaluation of CVD management quality by clinical audit projects in many settings. To support the development of clinical standards, monitor daily practice performance, and improve quality of care in CVD management at national and international levels, more widespread clinical audits are warranted.

  20. Selection of quality assurance programme levels for nuclear power plants. Present practice in Canada and future developments

    International Nuclear Information System (INIS)

    Thomas, R.A.

    1982-01-01

    According to the IAEA Code of Practice on the subject and also to numerous national standards, effective quality assurance (QA) for safety in nuclear power plants depends upon the application of a number of fundamental principles. One of these principles is that QA for systems, components and structures should be commensurate with the individual importance to safety of each item. Evidently, money spent on excessive QA may be partly or wholly wasted, while too little QA will provide insufficient confidence that an item will perform satisfactorily in service. To deal successfully with the requirement of 'importance to safety', a detailed methodology must be established, by means of which QA can be prescribed rationally and consistently. Set in the context of the Canadian nuclear power and nuclear standards programmes, two related methodologies which account for importance to safety as well as for some other specific factors have been developed and are in use. These related methodologies are applied to the manufacture and installation of safety-related items, and are based on the implementation of the fixed-step, graded standards of the Canadian Standards Association, CSA Z299. Information is presented on the main features of the methodologies and on Canadian nuclear power plant QA practice in general. (author)

    2010-01-01

    The importance of Nondestructive Testing (NDT) as a Quality Control/Quality Assurance tool in the industrial domain cannot be over-emphasized. With the rapid advancement in research and technology, the NDT field is becoming larger and more sophisticated day by day. Innovative research in materials science and digital technology is paving the way for more and more new methods in NDT technology. Although the NDT technology has improved over the years, the basic 'human factor' underlying the success of the NDT field remains the same. There are two major factors that influence the 'Quality Assurance in NDT'. First, knowledgeable and skilled NDT Operators are the most important factor in assuring the reliable test results. Second, the Management oversight of the NDT operations plays a major role in assuring the overall quality of NDT. Management responsibilities include the implementation of a Quality Management System (QMS) that focuses on the NDT operations and apply all the elements of Quality Assurance relevant to NDT. Whether the NDT operations are performed in-house or by a contractor, periodic Management Self-assessments should include the following question: How can the Management assess and improve the 'Quality Assurance in NDT'? This paper attempts to answer the above question. Some practical examples are provided to illustrate the potential quality incidents that could lead to costly failures, and the role of NDT Operator and the Management in preventing such quality incidents. Also, some guidelines are provided on how the Management can apply the elements of Quality Assurance to NDT in order to assess and improve the 'Quality Assurance in NDT'. (author)

    1997-01-01

    In Finland, the general principles and objectives of the QA are being more and more incorporated in the basic curricula of radiotherapy professionals: radiotherapists, radiation technologists (nurses), and the physicists, in particular. The medical physicists are identified as an independent specialty which, after the general studies in physics requires a special examination and five years practicing in various aspects of radiotherapy clinical work. Specific meetings organized both occasionally and regularly by national societies, hospitals and the authorities collect together different specialists in the field, thus providing opportunities for continuous up-keeping of knowledge and the exchange of experiences in QA. The Finnish Centre for Radiation and nuclear Safety (STUK), operating under the Ministry of Social Affairs and Health, is the national authority for radiation protection covering all fields of the application of radiation. Besides its supervisory role, i.e. to control that the safety of various applications meets the requirements et by legislation, considerable amount of the resources are devoted to research in support of the supervisory activities. For radiotherapy, the leading principle is to ensure the safety of patients, personnel and the public, the good accuracy of the dose to the patient being one of the main objectives. In essence, this leading principle manifests itself through the maintenance of standards, measurement techniques and calibration services traceable to the international measurement system, and through the legal inspections as well as independent reviews and measurements to assess the QA systems of hospitals (i.e. through Dosimetry Audits or Quality Audits)

    1994-07-01

    The definition of terms and connotation of "Quality", "Quality Assurance" and "Integration" lead to an analysis and understanding of inhibiting and fostering factors of the "Health Triad" of people, animals and environment. Although "Quality" is largely or ultimately determined by the consumer, there are considerable differences as this term is applied by (a) the individual consumer, (b) the dynamic producer defending or gaining markets, (c) those engaged in traditional product manufacturing, or (d) governments setting (minimum) requirements for the sake of free trade. "Quality Assurance" offers cooperation of partners all along the food chain from "pasture to table". The managerial process turned into a continuum of responsibility and agreement on processes and product characteristics. This overcomes the disadvantages of strategies stressing distinct defense barriers. In practice this philosophy of a predominant role of defence barriers proved largely partnership destructive, in that it permitted to shift responsibilities for failures and to claim administrative competence according to momentary situations and interests. "Integrated Quality Assurance" means mutual agreement of two or more partners along the food chain (e. g. feed producers, farmers, animal health industry, veterinarians and food processors) on product characteristics and production methods. It involves essential system elements including facilities, materials, manpower, information, transport, management etc. Different principles and procedures of quality assurance have been introduced in practice, including agriculture and food processing. These different approaches are not mutually exclusive but largely of complementary nature.(ABSTRACT TRUNCATED AT 250 WORDS)

  13. Measurement quality assurance

    International Nuclear Information System (INIS)

    Eisenhower, E.H.

    1988-01-01

    The quality of a radiation protection program can be no better than the quality of the measurements made to support it. In many cases, that quality is unknown and is merely implied on the basis of a calibration of a measuring instrument. If that calibration is inappropriate or is performed improperly, the measurement result will be inaccurate and misleading. Assurance of measurement quality can be achieved if appropriate procedures are followed, including periodic quality control actions that demonstrate adequate performance. Several national measurement quality assurance (MQA) programs are operational or under development in specific areas. They employ secondary standards laboratories that provide a high-quality link between the National Bureau of Standards and measurements made at the field use level. The procedures followed by these secondary laboratories to achieve MQA will be described, as well as plans for similar future programs. A growing general national interest in quality assurance, combined with strong specific motivations for MQA in the area of ionizing radiation, will provide continued demand for appropriate national programs. Such programs must, however, employ procedures that are cost effective and must be developed with participation by all affected parties

    Software Quality Assurance (SQA) is a planned and systematic set of activities that ensures conformance of software life cycle processes and products conform to requirements, standards and procedures. In software development, software quality means meeting requirements and a degree of excellence and refinement of a project or product. Software Quality is a set of attributes of a software product by which its quality is described and evaluated. The set of attributes includes functionality, reliability, usability, efficiency, maintainability, and portability. Software Metrics help us understand the technical process that is used to develop a product. The process is measured to improve it and the product is measured to increase quality throughout the life cycle of software. Software Metrics are measurements of the quality of software. Software is measured to indicate the quality of the product, to assess the productivity of the people who produce the product, to assess the benefits derived from new software engineering methods and tools, to form a baseline for estimation, and to help justify requests for new tools or additional training. Any part of the software development can be measured. If Software Metrics are implemented in software development, it can save time, money, and allow the organization to identify the caused of defects which have the greatest effect on software development. The summer of 2004, I worked with Cynthia Calhoun and Frank Robinson in the Software Assurance/Risk Management department. My task was to research and collect, compile, and analyze SQA Metrics that have been used in other projects that are not currently being used by the SA team and report them to the Software Assurance team to see if any metrics can be implemented in their software assurance life cycle process.

    After a brief review of the origin of the 'quality concept' and the historical development of quality assurance, questions such as 'what is QA' and 'why is QA so important in nuclear technology' as well as definitions and main requirements of relevant QA codes and standards are presented and discussed. By means of a project realization schematic, tasks, duties, responsibilities, and possible QA organigrammes as well as QA programme and manual requirements are explained and compared. From a QA point of view, it is shown that no basic difference exists between design and production or construction control activities. Special emphasis is layed upon active owner's participation in the implementation of QA programmes for NPP and the advantages offered are described and illustrated by typical examples. (RW) [de

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) presents the results of a preliminary project that examined how quality assurance methods can be used in the optimisation of small-scale hydropower projects. The aim of the project, to use existing know-how, experience and synergies, is examined. Discrepancies in quality and their effects on production prices were determined in interviews. The paper describes best-practice guidelines for the quality assurance of small-scale hydro schemes. A flow chart describes the various steps that have to be taken in the project and realisation work. Information collected from planners and from interviews made with them are presented along with further information obtained from literature. The results of interviews concerning planning work, putting to tender and the construction stages of these hydro schemes are presented and commented on. Similarly, the operational phase of such power plant is also examined, including questions on operation and guarantees. The aims of the follow-up main project - the definition of a tool and guidelines for ensuring quality - are briefly reviewed.

  20. Quality assurance in radiotherapy

    International Nuclear Information System (INIS)

    2003-03-01

    Good radiotherapy results and safety of treatment require the radiation to be optimally applied to a specified target area and the correct dose. According to international recommendations, the average uncertainty in therapeutic dose should not exceed 5%. The need for high precision in therapeutic dose requires quality assurance covering the entire radiotherapy process. Besides the physical and technical characteristics of the therapy equipment, quality assurance must include all radiotherapy equipment and procedures that are significant for the correct magnitude and precision of application of the therapeutic dose. The duties and responsibilities pertaining to various stages of treatment must also be precisely defined. These requirements may be best implemented through a quality system. The general requirements for supervision and quality assurance of medical radiation apparatus are prescribed in section 40 of the Radiation Act (592/1991, amendment 1142/1998) and in sections 18 and 32 of the Decree of the Ministry of Social Affairs and Health on the medical use of radiation (423/2000). Guide ST 2.2 imposes requirements on structural radiation shielding of radiotherapy equipment and the premises in which it is used, and on warning and safety arrangements. Guide ST 1.1 sets out the general safety principles for radiation practices and regulatory control procedure for the use of radiation. Guide ST 1.6 provides general requirements for operational measures in the use of radiation. This Guide sets out the duties of responsible parties (the party running a radiation practice) in respect of arranging and maintaining radiotherapy quality assurance. The principles set out in this Guide and Guide ST 6.3 may be applied to radionuclide therapy

    In 2000, the Norwegian Radiation Protection Authority (N.R.P.A.) initiated work to develop a national quality assurance programme in radiotherapy. The program was named K.V.I.S.T.: i.e. Norwegian abbreviation of Quality Assurance in Radiotherapy (KValitetSikring STraleterapi). The programme is performed by the multidisciplinary K.V.I.S.T. Group and aims to stimulate collaboration by focussing on clinical, technical and administrative problems that can be addressed and solved on a national level. An important objective is to establish a positive attitude towards quality assurance and better communication between centres and the various professions and professionals involved in radiotherapy, i.e. the oncologists, medical physicists and radiation therapy technologists. Information is also provided to other stake holders such as health authorities, hospital administrators and patients. In 2007 radiotherapy in Norway represent 10 departments and forty accelerators. Since radiotherapy is given high priority in cancer care good quality assurance is required. The member of the K.V.I.S.T.-group are part time at N.R.P.A. and part time in different radiotherapy departments. Professionals with competencies within radiotherapy (R.T.) have permanent positions in a national public entity. The K.V.I.S.T.-group is multidisciplinary. The K.V.I.S.T.-group acts as a coordinating group for all type of national Q.A. projects. The recommendations/guidelines are developed by national consensus. The work is performed by the radiotherapy community it self, thus creating an atmosphere of ownership. (N.C.)

    Safety requirements set forth in the regulatory requirement, codes, standards as well as other requirements for various aspects of nuclear power plant design and operation are strictly implemented through QA activities. The overall QA aim is to assure that the plant is soundly and correctly designed and that it is built, tested and operated in accordance with stringent quality standards and conservative engineering practices. In this way a high degree of freedom from faults and errors can be achieved. (orig.)

    To assess the quality and accuracy of primary grading in the Bristol and Weston diabetic retinopathy screening programme and to set standards for future interobserver agreement reports. A prospective audit of 213 image sets from six fully trained primary graders in the Bristol and Weston diabetic retinopathy screening programme was carried out over a 4-week period. All the images graded by the primary graders were regraded by an expert grader blinded to the primary grading results and the identity of the primary grader. The interobserver agreement between primary graders and the blinded expert grader and the corresponding Kappa coefficient was determined for overall grading, referable, non-referable and ungradable disease. The audit standard was set at 80% for interobserver agreement with a Kappa coefficient of 0.7. The interobserver agreement bettered the audit standard of 80% in all the categories. The Kappa coefficient was substantial (0.7) for the overall grading results and ranged from moderate to substantial (0.59-0.65) for referable, non-referable and ungradable disease categories. The main recommendation of the audit was to provide refresher training for the primary graders with focus on ungradable disease. The audit demonstrated an acceptable level of quality and accuracy of primary grading in the Bristol and Weston diabetic retinopathy screening programme and provided a standard against which future interobserver agreement can be measured for quality assurance within a screening programme.

  7. Helical Tomotherapy Quality Assurance

    International Nuclear Information System (INIS)

    Balog, John; Soisson, Emilie

    2008-01-01

    Helical tomotherapy uses a dynamic delivery in which the gantry, treatment couch, and multileaf collimator leaves are all in motion during treatment. This results in highly conformal radiotherapy, but the complexity of the delivery is partially hidden from the end-user because of the extensive integration and automation of the tomotherapy control systems. This presents a challenge to the medical physicist who is expected to be both a system user and an expert, capable of verifying relevant aspects of treatment delivery. A related issue is that a clinical tomotherapy planning system arrives at a customer's site already commissioned by the manufacturer, not by the clinical physicist. The clinical physicist and the manufacturer's representative verify the commissioning at the customer site before acceptance. Theoretically, treatment could begin immediately after acceptance. However, the clinical physicist is responsible for the safe and proper use of the machine. In addition, the therapists and radiation oncologists need to understand the important machine characteristics before treatment can proceed. Typically, treatment begins about 2 weeks after acceptance. This report presents an overview of the tomotherapy system. Helical tomotherapy has unique dosimetry characteristics, and some of those features are emphasized. The integrated treatment planning, delivery, and patient-plan quality assurance process is described. A quality assurance protocol is proposed, with an emphasis on what a clinical medical physicist could and should check. Additionally, aspects of a tomotherapy quality assurance program that could be checked automatically and remotely because of its inherent imaging system and integrated database are discussed

  8. Quality Assurance in Environmental Technology Verification (ETV): Analysis and Impact on the EU ETV Pilot Programme Performance

    Molenda, Michał; Ratman-Kłosińska, Izabela

    2018-03-01

    Many innovative environmental technologies never reach the market because they are new and cannot demonstrate a successful track record of previous applications. This fact is a serious obstacle on their way to the market. Lack of credible data on the performance of a technology causes mistrust of investors in innovations, especially from public sector, who seek effective solutions however without compromising the technical and financial risks associated with their implementation. Environmental technology verification (ETV) offers a credible, robust and transparent process that results in a third party confirmation of the claims made by the providers about the performance of the novel environmental technologies. Verifications of performance are supported by high quality, independent test data. In that way ETV as a tool helps establish vendor credibility and buyer confidence. Several countries across the world have implemented ETV in the form of national or regional programmes. ETV in the European Union was implemented as a voluntary scheme if a form of a pilot programme. The European Commission launched the Environmental Technology Pilot Programme of the European Union (EU ETV) in 2011. The paper describes the European model of ETV set up and put to operation under the Pilot Programme of Environmental Technologies Verification of the European Union. The goal, objectives, technological scope, involved entities are presented. An attempt has been made to summarise the results of the EU ETV scheme performance available for the period of 2012 when the programme has become fully operational until the first half of 2016. The study was aimed at analysing the overall organisation and efficiency of the EU ETV Pilot Programme. The study was based on the analysis of the documents the operation of the EU ETV system. For this purpose, a relevant statistical analysis of the data on the performance of the EU ETV system provided by the European Commission was carried out.

  9. Quality assurance and quality control

    International Nuclear Information System (INIS)

    Anon.

    1987-01-01

    The practice of nuclear diagnostic imaging requires an appropriate quality assurance program to attain high standards of efficiency and reliability. The International Atomic Energy Agency defines the term quality assurance as ''the closeness with which the outcome of a given procedure approaches some ideal, free from all errors and artifacts.'' The term quality control is used in reference to the specific measures taken to ensure that one particular aspect of the procedure is satisfactory. Therefore, quality assurance is a hospital-wide concept that should involve all aspects of clinical practice. Quality control is concerned with the submission of requests for procedures; the scheduling of patients; the preparation and dispensing of radiopharmaceuticals; the protection of patients, staff, and the general public against radiation hazards and accidents caused by radioactive materials or by faulty equipment; the setting up, use, and maintenance of electronic instruments; the methodology of the actual procedures; the analysis and interpretation of data; the reporting of results; and, finally, the keeping of records. The chapter discusses each of these areas

    Four national External Audit Groups (EAG) in charge of operating quality audits for radiotherapy dosimetry have been created through a Co-ordinated Research Programme ''Development of a Quality Assurance Programme for Radiation Therapy Dosimetry in Developing Countries'' (E2-40-07). The present status of the development of the measuring systems and measuring procedures for the EAGs has been compared to the methodology established by Quality Audit Networks operating at present in Europe. To harmonize different EAG procedures, a document entitled ''Guidelines to prepare a Quality Manual for External Audit Groups on Dosimetry in Radiotherapy '' has been outlined and a first draft prepared. The ''Guidelines...'' covers quality policy, quality systems and quality structures including process control following the recommendations of ISO 9000 series and ISO/IEC guide No. 25. When completed, this document can be used as a guide on how to prepare the quality manual for national EAGs in developing countries. Due to increased interest in the project three new participants have been admitted. (author)

    1995-05-01

    Quality assurance (QA) concerns the validity of all the analytical processes (from collection of the samples to interpretation of the results). It is not an abstract concept but must be adapted to the different situations such as the different exposure levels, the different analytical methods, and the context of use (risk assessment procedures, research, routine determinations). The main requirements in QA programmes regard the control of all the known sources of preanalytical and analytical variations, while the instruments with which adequate QA can be implemented are the certified materials and the quality control programmes (quality manual, internal and external quality controls). Another important concept in QA is that measurements must be placed a different metrological levels: at the highest there are the methods (definitive, reference) to be used for assessing accuracy of routine methods. QA programmes should enable a grading of biomarkers (from experimental only to full evaluated) and of the laboratories in order to identify the significance of the test and to assess the level at which a laboratory could operate.

  15. Quality assurance and reliability

    International Nuclear Information System (INIS)

    1975-01-01

    Concern for obtaining high-quality products which will function properly when required to do so is nothing new - it is one manifestation of a conscientious attitude to work. However, the complexity and cost of equipment and the consequences of even temporary immobilization are such that it has become necessary to make special arrangements for obtaining high-quality products and examining what one has obtained. Each unit within an enterprise must examine its own work or arrange for it to be examined; a unit whose specific task is quality assurance is responsible for overall checking, but does not relieve other units of their responsibility. Quality assurance is a form of mutual assistance within an enterprise, designed to remove the causes of faults as far as possible. It begins very early in a project and continues through the ordering stage, construction, start-up trials and operation. Quality and hence reliability are the direct result of what is done at all stages of a project. They depend on constant attention to detail, for even a minor piece of poor workmanship can, in the case of an essential item of equipment, give rise to serious operational difficulties

    The safe terminal containment of hazardous wastes cannot only rely upon the geographic remoteness and the arid climates of the repository sites. Radioactive and permanently toxic chemical wastes must by prevented from returning to the human environment by natural and engineered barriers. The long-term integrity of these barriers and the safety of waste emplacement operation will be controlled by systematic actions under the common objective of Quality Assurance (QA). The following paper presents the aims of QA in the design and production of waste packages. It lists the most relevant acceptance criteria and regulatory requirements, investigates the institutional and technical problems of carrying out Quality Assurance and presents suggestions for establishing suitable organizational structures and technical programmes to provide adequate confidence in the safe nature and the performance of waste packages. In view of the technical difficulties of verifying the compliance of industrially produced waste forms with the acceptance criteria, the CEC has laid emphasis on the development of appropriate test methods in its last R and D programme. First results of the work are reviewed in the context of international progress in this field

    Inter-fraction and intra-fraction motion management methods are increasingly applied clinically and require the development of advanced motion platforms to facilitate testing and quality assurance program development. The aim of this study was to assess the performance of a 5 degrees-of-freedom (DoF) programmable motion platform HexaMotion (ScandiDos, Uppsala, Sweden) towards clinically observed tumor motion range, velocity, acceleration and the accuracy requirements of SABR prescribed in AAPM Task Group 142. Performance specifications for the motion platform were derived from literature regarding the motion characteristics of prostate and lung tumor targets required for real time motion management. The performance of the programmable motion platform was evaluated against (1) maximum range, velocity and acceleration (5 DoF), (2) static position accuracy (5 DoF) and (3) dynamic position accuracy using patient-derived prostate and lung tumor motion traces (3 DoF). Translational motion accuracy was compared against electromagnetic transponder measurements. Rotation was benchmarked with a digital inclinometer. The static accuracy and reproducibility for translation and rotation was quality assurance and commissioning of motion management systems in radiation oncology.

    International Nuclear Information System (INIS)

    Kilian, H.J.

    1987-01-01

    Negative experience made during World War II led to the idea of quality assurance being born in the United States. Thoroughly misunderstood, it came to be incorporated in European mechanical engineering. Quality assurance there was initially considered to be a new term for the oganizational combination of all parts of an enterprise dealing with testing. German manufacturers of heavy-duty and safety fittings represented in the international market were compelled at a relatively early date to properly understand and realize a quality assurance programme. But the multi-fariousness of specifications to be applied and great number of the most different parts made eminent demands on the suitability and variability of the products developed. On the basis of 18 quality criteria the article describes the structure of 'quality' and what its consequences are for an effective quality assurance system - suited for all kinds of specifications.

    This paper describes the role of the quality assurance liaison, the responsibilities of this position, and the evolutionary changes in duties over the last six years. The role of the quality assurance liaison has had a very positive impact on the Los Alamos Yucca Mountain Site Characterization (YW) quality assurance program. Having both technical and quality assurance expertise, the quality assurance liaisons are able to facilitate communications with scientists on quality assurance issues and requirements, thereby generating greater productivity in scientific investigations. The quality assurance liaisons help ensure that the scientific community knows and implements existing requirements, is aware of new or changing regulations, and is able to conduct scientific work within Project requirements. The influence of the role of the quality assurance liaison can be measured by an overall improvement in attitude of the staff regarding quality assurance requirements and improved job performance, as well as a decrease in deficiencies identified during both internal and external audits and surveillances. This has resulted in a more effective implementation of quality assurance requirements

  3. Quality assurance for the safe transport of radioactive material

    International Nuclear Information System (INIS)

    1994-01-01

    All activities related to the safe transport of radioactive material should be covered by a quality assurance programme. This publication recognizes that a single transport operation often involves several different organizations, each having specific responsibilities. Hence, it is unlikely that the operation will be covered by a single quality assurance programme. Each quality assurance programme should be tailored to the specific organizational structure for which the programme is prepared, with account taken of the particular transport activities of that organization and the interfaces with other organizations. The aim of this publication is to give a detailed interpretation of what must be done by whom to produce a quality assurance programme for radioactive material transport. This publication provides guidance on methods and practical examples to develop QA programmes for the safe transport of radioactive material. It provides information on how to develop the programme, the standards and the common features of a QA programme

    The European Union Council Directive 97/43/Euratom of 30 June 1997 on health protection of individuals against the dangers of ionizing radiation in relation to medical exposure has been partially transposed to the Spanish national law by the Real Decreto 1976/1999, which establishes the quality criteria in Diagnostic Radiology. A key instrument in this legal regulation is the so-called Quality Assurance Program (QAP) which has to be implemented in each Diagnostic Radiology unit. The Spanish Breast Imaging Diagnostic Society (Sociedad Espanola de Diagnostico por Imagen de la Mama, SEDIM) has proposed a reference QAP to be used as a guide in all the mammography units in the country. Its main issues are displayed in the present paper. The SEDIM QAP includes some items related to justification and optimization of mammography exams as well as a proposal for the assignment of functions and responsibilities. A guide for the image and technical parameters quality evaluation is also included. Some keys on equipment acquisition, maintenance and on continuing education and information management can also be found in that document. (author)

    2002-08-01

    A Department of Health Executive Letter stated in 1998 that the principal function of external quality assessment (EQA) is educational. Subsequently, in England, it has no longer been acceptable to assess performance in gynaecological cytology by proficiency testing. This paper describes the EQA scheme in gynaecological cytology that has been run by the Trent Regional Gynaecological Pathology Quality Assurance Group for the NHS Cervical Screening Programme (NHSCSP) since 1998. It conforms as closely as possible to the recommendations published by the Department of Health Working Group on Histopathology EQA Accreditation, and replaced the national proficiency testing protocol. The educational value of the scheme is derived predominantly from a numerical score which provides confidential and quantitative feedback to all participants. Personal performance monitoring occurs as a secondary function. For primary screeners and checkers, this is based purely on the distinction between negative, inadequate and abnormal smears. For pathologists, personal performance monitoring also includes grading of abnormalities. The EQA has been designed so that all professional groups participate in a manner that closely mimics normal practice. Only slides that have achieved an 80% consensus amongst participants are used in the EQA. Substandard performance has been defined as those participants with scores falling below the 2.5%ile. The paper describes the EQA in detail and illustrates its use by means of the second round results. The EQA protocol developed within Trent and described in this paper has contributed to proposals contained in the current national EQA in gynaecological cytology for the NHSCSP. In particular this paper highlights the effectiveness of the scoring system contained within the Trent and National EQA protocols.

  10. Nuclear power plants - Quality assurance

    International Nuclear Information System (INIS)

    1980-01-01

    This International Standard defines principles for the establishment and implementation of quality assurance programmes during all phases of design, procurement, fabrication, construction, commissioning, operation, maintenance and decommissioning of structures, systems and components of nuclear power plants. These principles apply to activities affecting the quality of items, such as designing, purchasing, fabricating, handling, shipping, storing, cleaning, erecting, installing, testing, commissioning, operating, inspecting, maintaining, repairing, refuelling and modifying and eventually decommissioning. The manner in which the principles described in this document will be implemented in different organizations involved in a specific nuclear power project will depend on regulatory and contractual requirements, the form of management applied to a nuclear power project, and the nature and scope of the work to be performed by different organizations

    1997-01-01

    In 1996, the Joint Commission International (JCI), which is a partnership between the Joint Commission on Accreditation of Healthcare Organizations and Quality Healthcare Resources, Inc., became one of the contractors of the Quality Assurance Project (QAP). JCI recognizes the link between accreditation and quality, and uses a collaborative approach to help a country develop national quality standards that will improve patient care, satisfy patient-centered objectives, and serve the interest of all affected parties. The implementation of good standards provides support for the good performance of professionals, introduces new ideas for improvement, enhances the quality of patient care, reduces costs, increases efficiency, strengthens public confidence, improves management, and enhances the involvement of the medical staff. Such good standards are objective and measurable; achievable with current resources; adaptable to different institutions and cultures; and demonstrate autonomy, flexibility, and creativity. The QAP offers the opportunity to approach accreditation through research efforts, training programs, and regulatory processes. QAP work in the area of accreditation has been targeted for Zambia, where the goal is to provide equal access to cost-effective, quality health care; Jordan, where a consensus process for the development of standards, guidelines, and policies has been initiated; and Ecuador, where JCI has been asked to help plan an approach to the evaluation and monitoring of the health care delivery system.

    As a result of the Three Mile Island accident and the findings presented in various investigatory reports, some fundamental changes are taking place in the role and scope of quality assurance. Recent changes to United States national codes, guides and standards are analysed in order to identify the principles involved. This analysis shows that the scope of the programme is being extended beyond the equipment designated 'nuclear safety related' and greater emphasis is being placed upon the independent verification of the satisfactory performance of activities affecting safety. Such fundamental changes could lead to a significant increase in the number of quality assurance personnel required to support an operating nuclear power plant. The evolving quality assurance organization at Three Mile Island is used to illustrate how these fundamental changes could affect the quality assurance organization and manpower requirements.

    Cotelo, E.; Pouso, J.; Reyes, W.

    2001-01-01

    Radiofrequency Cardiac Catheter Ablation is an Interventional Radiology procedure of great complexity because the cardiologist needs a simultaneous evaluation of fluoroscopic images and electrophysiologic information. Therefore, the procedure typically involves extended fluoroscopic time that may cause radiation-skin injures to patients. Skin doses depend on many factors: equipment design features and its proper use, cardiologist practice, fluoroscopic time, irradiated areas, application of radiation protection recommendations, etc. We evaluate fluoroscopic time in relation to pathology and we estimate skin doses on 233 procedures at the Electrophysiology Laboratory in Casa de Galicia, Montevideo, Uruguay. Significant differences among the medians of fluoroscopic time were found in those procedures depending on diagnoses and results. Higher fluoroscopic time was found in flutter and auricular tachycardia (median was 83 minutes, p=0.0001). In successful procedures (almost 90%), median skin doses was 2.0 Grays (p=0.0001). On the basis of records information, the standard operating procedure and the clinical protocol, expanding close cooperation between the cardiologists and the experts in Radiation Protection will secure the establishment of an Assurance Quality Program.

    FESA is a framework used by 100+ developers at CERN to design and implement the real-time software used to control the accelerators. Each new version must be tested and qualified to ensure that no backward compatibility issues have been introduced and that there is no major bug which might prevent accelerator operations. Our quality assurance approach is based on code review and a two-level testing process. The first level is made of unit-test (Python unittest & Google tests for C++). The second level consists of integration tests running on an isolated test environment. We also use a continuous integration service (Bamboo) to ensure the tests are executed periodically and the bugs caught early. In the presentation, we will explain the reasons why we took this approach, the results and some thoughts on the pros and cons.

    One objective of the Kenya National Malaria Strategy 2009-2017 is scaling access to prompt diagnosis and effective treatment. In 2013, a quality assurance (QA) pilot was implemented to improve accuracy of malaria diagnostics at selected health facilities in low-transmission counties of Kenya. Trends in malaria diagnostic and QA indicator performance during the pilot are described. From June to December 2013, 28 QA officers provided on-the-job training and mentoring for malaria microscopy, malaria rapid diagnostic tests and laboratory QA/quality control (QC) practices over four 1-day visits at 83 health facilities. QA officers observed and recorded laboratory conditions and practices and cross-checked blood slides for malaria parasite presence, and a portion of cross-checked slides were confirmed by reference laboratories. Eighty (96%) facilities completed the pilot. Among 315 personnel at pilot initiation, 13% (n = 40) reported malaria diagnostics training within the previous 12 months. Slide positivity ranged from 3 to 7%. Compared to the reference laboratory, microscopy sensitivity ranged from 53 to 96% and positive predictive value from 39 to 53% for facility staff and from 60 to 96% and 52 to 80%, respectively, for QA officers. Compared to reference, specificity ranged from 88 to 98% and negative predictive value from 98 to 99% for health-facility personnel and from 93 to 99% and 99%, respectively, for QA officers. The kappa value ranged from 0.48-0.66 for facility staff and 0.57-0.84 for QA officers compared to reference. The only significant test performance improvement observed for facility staff was for specificity from 88% (95% CI 85-90%) to 98% (95% CI 97-99%). QA/QC practices, including use of positive-control slides, internal and external slide cross-checking and recording of QA/QC activities, all increased significantly across the pilot (p malaria QA/QC practices over the pilot.

    Background Colposcopy, the key step in the management of women with abnormal Pap smear results, is a visual technique prone to observer variation, which implies the need for prolonged apprenticeship, continuous training, and quality assurance (QA) measures. Colposcopy QA programmes vary in level of responsibility of organizing subjects, geographic coverage, scope, model, and type of actions. The programmes addressing the clinical standards of colposcopy (quality of examination and appropriateness of clinical decisions) are more limited in space and less sustainable over time than those focused on the provision of the service (resources, accessibility, etc.). This article reports on the protocol of a QA programme targeting the clinical quality of colposcopy in a population-based cervical screening service in an administrative region of northern Italy. Methods/design After a situation analysis of local colposcopy audit practices and previous QA initiatives, a permanent web-based QA programme was developed. The design places more emphasis on providing education and feedback to participants than on testing them. The technical core is a log-in web application accessible on the website of the regional Administration. The primary objectives are to provide (1) a practical opportunity for retraining of screening colposcopists, and (2) a platform for them to interact with colposcopists from other settings and regions through exchange and discussion of digital colposcopic images. The retraining function is based on repeated QA sessions in which the registered colposcopists log-in, classify a posted set of colpophotographs, and receive on line a set of personal feedback data. Each session ends with a plenary seminar featuring the presentation of overall results and an interactive review of the test set of colpophotographs. This is meant to be a forum for an open exchange of views that may lead to more knowledge and more diagnostic homogeneity. The protocol includes the

    Lot quality assurance sampling (LQAS) with two-stage sampling plan was applied for rapid monitoring of coverage after every round of mass drug administration (MDA). A Primary Health Centre (PHC) consisting of 29 villages in Thiruvannamalai district, Tamil Nadu was selected as the study area. Two threshold levels of coverage were used: threshold A (maximum: 60%; minimum: 40%) and threshold B (maximum: 80%; minimum: 60%). Based on these thresholds, one sampling plan each for A and B was derived with the necessary sample size and the number of allowable defectives (i.e. defectives mean those who have not received the drug). Using data generated through simple random sampling (SRSI) of 1,750 individuals in the study area, LQAS was validated with the above two sampling plans for its diagnostic and field applicability. Simultaneously, a household survey (SRSH) was conducted for validation and cost-effectiveness analysis. Based on SRSH survey, the estimated coverage was 93.5% (CI: 91.7-95.3%). LQAS with threshold A revealed that by sampling a maximum of 14 individuals and by allowing four defectives, the coverage was >or=60% in >90% of villages at the first stage. Similarly, with threshold B by sampling a maximum of nine individuals and by allowing four defectives, the coverage was >or=80% in >90% of villages at the first stage. These analyses suggest that the sampling plan (14,4,52,25) of threshold A may be adopted in MDA to assess if a minimum coverage of 60% has been achieved. However, to achieve the goal of elimination, the sampling plan (9, 4, 42, 29) of threshold B can identify villages in which the coverage is LQAS are more cost-effective than SRSH to detect a village with a given level of coverage. The cost per village was US dollars 76.18 under SRSH. The cost of LQAS was US dollars 65.81 and 55.63 per village for thresholds A and B respectively. The total financial cost of classifying a village correctly with the given threshold level of LQAS could be reduced by

    This review describes the ballistic quality assurance for stereotactic intracranial irradiation treatments delivered with Gamma Knife R either dedicated or adapted medical linear accelerators. Specific and periodic controls should be performed in order to check the mechanical stability for both irradiation and collimation systems. If this step remains under the responsibility of the medical physicist, it should be done in agreement with the manufacturer's technical support. At this time, there are no recent published guidelines. With technological developments, both frequency and accuracy should be assessed in each institution according to the treatment mode: single versus hypo-fractionated dose, circular collimator versus micro-multi-leaf collimators. In addition, 'end-to-end' techniques are mandatory to find the origin of potential discrepancies and to estimate the global ballistic accuracy of the delivered treatment. Indeed, they include frames, non-invasive immobilization devices, localizers, multimodal imaging for delineation and in-room positioning imaging systems. The final precision that could be reasonably achieved is more or less 1 mm. (authors)

    The growth in cost and importance of software to NASA has caused NASA to address the improvement of software development across the agency. One of the products of this program is a series of guidebooks that define a NASA concept of the assurance processes that are used in software development. The Software Assurance Guidebook, NASA-GB-A201, issued in September, 1989, provides an overall picture of the NASA concepts and practices in software assurance. Second level guidebooks focus on specific activities that fall within the software assurance discipline, and provide more detailed information for the manager and/or practitioner. This is the second level Software Quality Assurance Audits Guidebook that describes software quality assurance audits in a way that is compatible with practices at NASA Centers.

    The customers satisfaction depends not only on functional performance, it also depends on the quality characteristics of the software products. An examination of this quality aspect of software products will provide a clear, well defined framework for quality assurance functions, which improve the life-cycle activities of software development. Software developers must be aware of the following aspects which have been expressed by many quality experts: quality cannot be added on; the level of quality built into a program is a function of the quality attributes employed during the development process; and finally, quality must be managed. These concepts have guided our development of the following definition for a Software Quality Assurance function: Software Quality Assurance is a formal, planned approach of actions designed to evaluate the degree of an identifiable set of quality attributes present in all software systems and their products. This paper is an explanation of how this definition was developed and how it is used.

    The National Health Service Breast Screening Programme (NHSBSP) is an example of a nationally coordinated quality assurance programme in which all the professional groups involved participate. Surgeons, radiologists and pathologists defined the clinical outcome measures against which they would subsequently be audited. The NHSBSP and the Association of Breast Surgery at BASO are jointly responsible for coordinating an annual audit of all surgical activities undertaken within the NHSBSP. The trends for key outcome measures between 1996 and 2001 are provided. The preoperative diagnosis rate (minimum standard 70 per cent or more) improved from 63 to 87 per cent. This rise was mirrored by an increase in the use of core biopsy in preference to fine-needle cytology. The proportion of patients in whom lymph node status was recorded improved from 81 to 93 per cent. There was no significant change in the number of women treated by low case-load surgeons and waiting times for surgery increased through the study interval. The BASO-NHSBSP Breast Audit has recorded major changes in clinical practice over 5 years. A key feature has been the dissemination of good practice through feedback of the results at local and national level. Copyright 2003 British Journal of Surgery Society Ltd.

    During the time of planing and construction of a nuclear power plant, the following proceeding is approved: - the deliverer of a nuclear power plant provides the reports fixing the quality assurance program, it means that he is responsible to write the safety analysis report, the specifications for the erection of the components, the working manuals and specifications for testing (eg nondestr. testing) - the manufacturing of components or systems will be controlled by an own independent quality assurance group, provided that this group was checked by the quality assurance group of the applicant - the TUeV with its independent assessors will fix the requirements relating to quality assurance in its assessment. On this basis the examination of the applicants specifications, working manuals, testing specifications will be done. The efficiency of quality assurance at the manufacturer and at the applicant will be checked by the TUeV specialists by considering specifications of modifications, repairs or tolerances. A mean point of the quality assurance in Germany is the dynamic adjustment, of an action on the latest state of engineering or science. If there exists a change of rules or guidelines, the quality assurance requirements have to be fit on this state in so far as it is feasible from the technical point of view. (orig./RW)

    Um, Dallsun

    For the radiation shielding quality assurance, the validity and reliability of the neutron transport code MCNP, which is now one of the most widely used radiation shielding analysis codes, were checked with lot of benchmark experiments. And also as a practical example, follows were performed in this thesis. One integral neutron transport experiment to measure the effect of neutron streaming in iron and void was performed with Dog-Legged Void Assembly in Knolls Atomic Power Laboratory in 1991. Neutron flux was measured six different places with the methane detectors and a BF-3 detector. The main purpose of the measurements was to provide benchmark against which various neutron transport calculation tools could be compared. Those data were used in verification of Monte Carlo Neutron & Photon Transport Code, MCNP, with the modeling for that. Experimental results and calculation results were compared in both ways, as the total integrated value of neutron fluxes along neutron energy range from 10 KeV to 2 MeV and as the neutron spectrum along with neutron energy range. Both results are well matched with the statistical error +/-20%. MCNP results were also compared with those of TORT, a three dimensional discrete ordinates code which was developed by Oak Ridge National Laboratory. MCNP results are superior to the TORT results at all detector places except one. This means that MCNP is proved as a very powerful tool for the analysis of neutron transport through iron & air and further it could be used as a powerful tool for the radiation shielding analysis. For one application of the analysis of variance (ANOVA) to neutron and gamma transport problems, uncertainties for the calculated values of critical K were evaluated as in the ANOVA on statistical data.

    Quality assurance is defined as the intentional and systematic activity carried out to obtain such reliability that the functions of nuclear power generating plants are demonstrated during the plant operation, and the section in charge has the role to organize, adjust and communicate so that the related sections can work smoothly. There are many documents concerning the quality assurance, such as quality assurance basic program, quality assurance manual, quality control plan and its manual and many specifications, etc. The content of the quality assurance is different for every step of plant planning such as at inquiry and order receiving, and prior to manufacturing, for example, inspection specification being decided for the material and the welded parts of classified pipings at the step of order receiving. Document management, engineering schedule and the custody of quality records are also quality assurance activities. Design management is controlled step by step; plant planning including safety analysis, overall layout plan, conceptual design of buildings, aseismatic design guide, heat balance and so on, system design mainly with system description, piping design including piping specification, standard dimensions of edge preparation, piping and valve lists, inspection manual, etc., detailed design, standardization of piping and design review, etc. are explained. The management of the intermediate between soft and hard parts consists of the quality check for material manufacturers and shipment inspection, etc. (Nakai, Y.)

    The IAEA directed extensive efforts during the years 1991 to 1995 to the integral revision of all NUSS quality assurance publications, which were approved and issued as Safety Series No.50-C/SG-Q, Quality Assurance for Safety in Nuclear Power Plants and other Nuclear Installations (1996). When these quality assurance publications were developed, their prime focus was on requirements against which work performed by the licensees could be measured and assessed by the regulatory bodies. In this way, they only helped to facilitate the functions of regulators. No requirements or recommendations were provided on how the regulators should ensure the effective implementation of their own activities. The present publication is a first attempt to collect, integrate and offer available experience to directly support performance of regulatory activities. It presents a comprehensive compilation on the application of quality assurance principles and methods by regulatory bodies to their activities. The aim is consistent good performance of regulatory activities through a systematic approach

    1992-12-01

    To meet the current standards of excellence necessary for blood establishments, we have learned from industry that a movement toward organization-wide quality assurance/total quality management must be made. Everyone in the organization must accept responsibility for participating in providing the highest quality products and services. Quality must be built into processes and design systems to support these quality processes. Quality assurance has been redefined to include a quality planning function described as the most effective way of designing quality into processes. A formalized quality planning process must be part of quality assurance. Continuous quality improvement has been identified as the strategy every blood establishment must support while striving for error-free processing as the long-term objective. The auditing process has been realigned to support and facilitate this same objective. Implementing organization-wide quality assurance/total quality management is one proven plan for guaranteeing the quality of the 20 million products that are transfused into 4 million patients each year and for moving toward the new order.

    Quality assurance contracts belong to the most important instruments of quality management systems. As a result of such contracts, quality control is to be done not only by the buyer, but is made a task to be fulfilled by the manufacturer. The author of the article shows that quality assurance contracts do change the contractual relationship between supplier and buyer, but have no effect on economic and practical conditions. This is so because quality assurance contracts apply only to warranty claims, which play a subordinate role in the legal relationship between producer and buyer, or producer and consumer, as compared to the claims for damages arising out of the contracts.

This trial concerns India's approach to addressing an increase in malaria-attributable deaths by training community health workers to diagnose, treat and prevent malaria, while using LQAS to monitor sub-district performance and make programme improvements. The Ministry of Health introduced LQAS into four matched high malaria burden districts (Annual Parasite Incidence >5) (N > 5 million). In each sub-district, we sampled four populations in three 6-monthly surveys: households, children LQAS results appeared to support district managers to increase coverage in underperforming areas, especially for vertical strategies in the presence of diligent managers. © 2014 The Authors.

    Experience of the Westinghouse Water Reactors Division with indoctrination and training of quality engineers includes training of personnel from Westinghouse divisions in the USA and overseas as well as of customers' personnel. A written plan is prepared for each trainee in order to fit the training to the individual's needs, and to cover the full range of information and activities. The trainee is also given work assignments, working closely with experienced quality engineers. He may prepare inspection plans and audit check lists, assist in the preparation of QA training modules, write procedures, and perform supplier surveillance and data analyses, or make special studies of operating systems. The trainee attends seminars and special courses on work-related technical subjects. Throughout the training period, emphasis is placed on inculcating an attitude of team work in the trainee so that the result of the training is the achievement of both quality and productivity. Certification is extended (given that education/experience/skill requirements are met) to such functions as mechanical equipment quality engineering, electrical equipment quality engineering, and start-up and testing quality engineering. A well-trained quality engineer is equipped to provide technical assistance to other disciplines and, through effective co-operation with others, contributes to the success of the organization's endeavours.

    Quality assurance in clinical studies aiming at approval of pharmaceutical products is submitted to strict rules, controls and auditing regulations. Comparative instruments to ensure quality in diagnostic and therapeutic procedures are not available in interventional cardiology, likewise in other fields of cardiovascular medicine. Quality assurance simply consists of "quality registers" with basic data not externally controlled. Based on the experiences of clinical studies and their long history of standardization it is assumed that these data may be severely flawed thus being inappropriate to set standards for diagnostic and therapeutic strategies. The precondition for quality assurance are quality data. In invasive coronary angiography and intervention medical indications, the decision making process interventional versus surgical revascularization, technical performance and after - care are essential aspects affecting quality of diagnostics and therapy. Quality data are externally controlled data. To collect quality data an appropriate infrastructure is a necessary precondition which is not existent. For an appropriate infrastructure investments have to be done both to build up as well as to sustain the necessary preconditions. As long as there are no infrastructure and no investments there will be no "quality data". There exist simply registers of data which are not proved to be a basis for significant assurance and enhancement in quality in interventional coronary cardiology.

    External dosimetry audits give confidence in the safe and accurate delivery of radiotherapy. The RTTQA group have performed an on-site audit programme for trial recruiting centres, who have recently implemented static or rotational IMRT, and those with major changes to planning or delivery systems. Measurements of reference beam output were performed by the host centre, and by the auditor using independent equipment. Verification of clinical plans was performed using the ArcCheck helical diode array. A total of 54 measurement sessions were performed between May 2014 and June 2016 at 28 UK institutions, reflecting the different combinations of planning and delivery systems used at each institution. Average ratio of measured output between auditor and host was 1.002±0.006. Average point dose agreement for clinical plans was -0.3±1.8%. Average (and 95% lower confidence intervals) of gamma pass rates at 2%/2mm, 3%/2mm and 3%/3mm respectively were: 92% (80%), 96% (90%) and 98% (94%). Moderately significant differences were seen between fixed gantry angle and rotational IMRT, and between combination of planning systems and linac manufacturer, but not between anatomical treatment site or beam energy. An external audit programme has been implemented for universal and efficient credentialing of IMRT treatments in clinical trials. Good agreement was found between measured and expected doses, with few outliers, leading to a simple table of optimal and mandatory tolerances for approval of dosimetry audit results. Feedback was given to some centres leading to improved clinical practice. Copyright © 2017 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd. All rights reserved.

    Malaria accounts for ~21% of outpatient visits annually in Kenya; prompt and accurate malaria diagnosis is critical to ensure proper treatment. In 2013, formal malaria microscopy refresher training for microscopists and a pilot quality-assurance (QA) programme for malaria diagnostics were independently implemented to improve malaria microscopy diagnosis in malaria low-transmission areas of Kenya. A study was conducted to identify factors associated with malaria microscopy performance in the same areas. From March to April 2014, a cross-sectional survey was conducted in 42 public health facilities; 21 were QA-pilot facilities. In each facility, 18 malaria thick blood slides archived during January-February 2014 were selected by simple random sampling. Each malaria slide was re-examined by two expert microscopists masked to health-facility results. Expert results were used as the reference for microscopy performance measures. Logistic regression with specific random effects modelling was performed to identify factors associated with accurate malaria microscopy diagnosis. Of 756 malaria slides collected, 204 (27%) were read as positive by health-facility microscopists and 103 (14%) as positive by experts. Overall, 93% of slide results from QA-pilot facilities were concordant with expert reference compared to 77% in non-QA pilot facilities (p malaria diagnosis. Microscopists who had recently completed refresher training and worked in a QA-pilot facility performed the best overall. The QA programme and formal microscopy refresher training should be systematically implemented together to improve parasitological diagnosis of malaria by microscopy in Kenya.

    Purpose. To report the accuracy of colposcopically directed biopsy in an internet-based colposcopy quality assurance programme in northern Italy. Methods. A web application was made accessible on the website of the regional Administration. Fifty-nine colposcopists out of the registered 65 logged in, viewed a posted set of 50 digital colpophotographs, classified them for colposcopic impression and need for biopsy, and indicated the most appropriate site for biopsy with a left-button mouse click on the image. Results. Total biopsy failure rate, comprising both nonbiopsy and incorrect selection of biopsy site, was 0.20 in CIN1, 0.11 in CIN2, 0.09 in CIN3, and 0.02 in carcinoma. Errors in the selection of biopsy site were stable between 0.08 and 0.09 in the three grades of CIN while decreasing to 0.01 in carcinoma. In multivariate analysis, the risk of incorrect selection of biopsy site was 1.97 for CIN2, 2.52 for CIN3, and 0.29 for carcinoma versus CIN1. Conclusions. Although total biopsy failure rate decreased regularly with increasing severity of histological diagnosis, the rate of incorrect selection of biopsy site was stable up to CIN3. In multivariate analysis, CIN2 and CIN3 had an independently increased risk of incorrect selection of biopsy site. PMID:26180805

    The present Manual provides guidance and illustrative examples for applying a method by which graded quality assurance requirements may be determined and adapted to the items and services of a nuclear power plant in conformance with the requirements of the IAEA Nuclear Safety Standards (NUSS) Code and Safety Guides on quality assurance. The Manual replaces the previous publication IAEA-TECDOC-303 on the same subject. Various methods of grading quality assurance are available in a number of Member States. During the development of the present Manual it was not considered practical to attempt to resolve the differences between those methods and it was preferred to identify and benefit from the good practices available in all the methods. The method presented in this Manual deals with the aspects of management, documentation, control, verification and administration which affect quality. 1 fig., 4 tabs

    This study reports on the results of a large-scale targeted condom social marketing campaign in and around areas where female sex workers are present. The paper also describes the method that was used for the routine monitoring of condom availability in these sites. The lot quality assurance sampling (LQAS) method was used for the assessment of the geographical coverage and quality of coverage of condoms in target areas in four states and along selected national highways in India, as part of Avahan, the India AIDS initiative. A significant general increase in condom availability was observed in the intervention area between 2005 and 2008. High coverage rates were gradually achieved through an extensive network of pharmacies and particularly of non-traditional outlets, whereas traditional outlets were instrumental in providing large volumes of condoms. LQAS is seen as a valuable tool for the routine monitoring of the geographical coverage and of the quality of delivery systems of condoms and of health products and services in general. With a relatively small sample size, easy data collection procedures and simple analytical methods, it was possible to inform decision-makers regularly on progress towards coverage targets.

  9. Quality assurance handbook for measurement laboratories

    Delvin, W.L.

    1984-10-01

    This handbook provides guidance in the application of quality assurance to measurement activities. It is intended to help those persons making measurements in applying quality assurance to their work activities by showing how laboratory practices and quality assurance requirements are integrated to provide control within those activities. The use of the guidance found in this handbook should help provide consistency in the interpretation of quality assurance requirements across all types of measurement laboratories. This handbook also can assist quality assurance personnel in understanding the relationships between laboratory practices and quality assurance requirements. The handbook is composed of three chapters and several appendices. Basic guidance is provided by the three chapters. In Chapter 1, the role of quality assurance in obtaining quality data and the importance of such data are discussed. Chapter 2 presents the elements of laboratory quality assurance in terms of practices that can be used in controlling work activities to assure the acquisition of quality data. Chapter 3 discusses the implementation of laboratory quality assurance. The appendices provide supplemental information to give the users a better understanding of the following: what is quality assurance; why quality assurance is required; where quality assurance requirements come from; how those requirements are interpreted for application to laboratory operations; how the elements of laboratory quality assurance relate to various laboratory activities; and how a quality assurance program can be developed

    1976-01-01

    While the safety record of the nuclear industry continues to be excellent, the forced outage rates for recent years continue to be 15% or more. Quality assurance, therefore, needs to be applied not only to nuclear safety matters, but to the goals of increased productivity and reduced construction and operating costs. Broadening the application of the general concept of quality assurance in this way leads to the introduction of reliability technology. The total activity might better be called reliability assurance. That effective quality assurance systems do pay off is described by examples from the utility industry, from a manufacturer of instruments and systems and from the experience of Westinghouse Electric Company's manufacturing divisions. The special situation of applying quality assurance to nuclear fuel is discussed. Problems include the lack of a fully developed regulatory policy in this area, incomplete understanding of the mechanism for pellet-clad interaction failures, incomplete access to manufacturers design and process information, inability to make desirable changes on a timely basis and inadequate feedback of irradiation experience.

    1993-01-01

    Lawrence Berkeley Laboratory's Environment Department addresses its responsibilities through activities in a variety of areas. The need for a comprehensive management control system for these activities has been identified by the Department of Energy (DOE). The WM QA (Waste Management Quality Assurance) Plan is an integral part of a management system that provides controls necessary to ensure that the department's activities are planned, performed, documented, and verified. This WM QA Plan defines the requirements of the WM QA program. These requirements are derived from DOE Order 5700.6C, Quality Assurance, the LBL Operating and Assurance Program Plan (OAP, LBL PUB-3111), and other environmental compliance documents applicable to WM activities. The requirements presented herein, as well as the procedures and methodologies that direct the implementation of these requirements, will undergo review and revisions as necessary. The provisions of this QA Plan and its implementing documents apply to quality-affecting activities performed by and for WM. It is also applicable to WM contractors, vendors, and other LBL organizations associated with WM activities, except where such contractors, vendors, or organizations are governed by their own WM-approved QA programs. References used in the preparation of this document are (1) ASME NQA-1-1989, (2) ANSI/ASQC E4 (Draft), (3) Waste Management Quality Assurance Implementing Management Plan (LBL PUB-5352, Rev. 1), (4) LBL Operating and Assurance Program Plan (OAP), LBL PUB-3111, 2/3/93.

    The WMG QAP is an integral part of a management system designed to ensure that WMG activities are planned, performed, documented, and verified in a manner that assures a quality product. A quality product is one that meets all waste acceptance criteria, conforms to all permit and regulatory requirements, and is accepted at the offsite treatment, storage, and disposal facility. In addition to internal processes, this QA Plan identifies WMG processes providing oversight and assurance to line management that waste is managed according to all federal, state, and local requirements for waste generator areas. A variety of quality assurance activities are integral to managing waste. These QA functions have been identified in the relevant procedures and in subsequent sections of this plan. The WMG QAP defines the requirements of the WMG quality assurance program. These requirements are derived from Department of Energy (DOE) Order 414.1C, Quality Assurance, Contractor Requirements Document, the LBNL Operating and Assurance Program Plan (OAP), and other applicable environmental compliance documents. The QAP and all associated WMG policies and procedures are periodically reviewed and revised, as necessary, to implement corrective actions, and to reflect changes that have occurred in regulations, requirements, or practices as a result of feedback on work performed or lessons learned from other organizations. The provisions of this QAP and its implementing documents apply to quality-affecting activities performed by the WMG; WMG personnel, contractors, and vendors; and personnel from other associated LBNL organizations, except where such contractors, vendors, or organizations are governed by their own WMG-approved QA programs

    International Nuclear Information System (INIS)

    2002-01-01

    FAO/IAEA support in the area of animal health is focused on enhancing the ability of regional reference laboratories and national veterinary authorities in developing countries to diagnose livestock diseases of major importance using nuclear and related technologies, and to help monitor the effectiveness of national and regional intervention strategies. This is done through provision of advice to the veterinary authorities concerning the development of appropriate sampling or research strategies coupled with FAO/IAEA-led collaborative development, adaptation, standardization, evaluation, and provision of quality-controlled enzyme-linked immunosorbent assay (ELISA) kits and the components necessary for diagnostic application of the polymerase chain reaction (PCR) techniques. Additional features of FAO/IAEA animal health support include provision of relevant laboratory equipment, training of counterpart scientists and technicians in the use of the equipment and standardized assays, and coordination of quality assurance (QA) programmes to monitor the proficiency of the assayists and help evaluate the impact of improved diagnostic capabilities. The current FAO/IAEA External Quality Assurance Programme (EQAP) for Animal Disease Diagnosis began as an effort to monitor the efficacy of mass vaccination programmes as part of the Pan African Rinderpest Campaign (PARC). Proficiency test panels, composed of 40 'unknown' serum samples, were sent to participating laboratories yearly to measure their abilities with ELISA in distinguishing between samples that were positive or negative for rinderpest antibodies. From this beginning, the EQAP has grown into an effort to measure general and specific components of FAO/IAEA counterparts' QA systems and provide assurance to outside observers that the use of FAO/IAEA diagnostic ELISA's are within established control limits and the test results and diagnostic interpretations are reliable. A major objective of the current EQAP is to

    1996-04-01

    Many nurse-researchers using qualitative strategies have been concerned with assuring quality in their work. The early literature reveals that the concepts of validity and reliability, as understood from the positivist perspective, are somehow inappropriate and inadequate when applied to interpretive research. More recent literature suggests that because of the positivist and interpretive paradigms are epistemologically divergent, the transfer of quality criteria from one perspective to the other is not automatic or even reasonable. The purpose of this article, therefore, is to clarify what the terms quality, trustworthiness, credibility, authenticity, and goodness mean in qualitative research findings. The process of assuring quality, validation, in qualitative research will be discussed within the context of the interpretive method, narrative analysis. A brief review of quality in narrative analysis nursing research will also be presented.

    This paper reports that the increased awareness of global environmental pollution has meant that analytical laboratories are faced with an increasing number of samples to analyze and a greater demand for quality control for their applications. In answer to these demands, more laboratory managers are turning to automation for analytical procedures and automated routines to perform quality control on individual samples. Atomic Absorption analysis, particularly by graphite furnace and hydride generation technique has proved to be adaptable to automated analysis to determine low concentrations of elements such as As, Co, Cd, Hg, Ag, Ba, Cr and Pb. Although highly sensitive, both techniques are time consuming and highly matrix dependent. They may also require extensive sample preparation prior to analysis. Additionally, government imposed methodologies e.g. those used for the USA EPA, Contract Laboratory Program, RCRA and SDWA programs, require very specific time consuming quality control measures

    Following publication of the Site-94 report, SKI wishes to review how Quality Assurance (QA) issues could be treated in future work both in undertaking their own Performance Assessment (PA) calculations and in scrutinising documents supplied by SKB (on planning a repository for spent fuels in Sweden). The aim of this report is to identify the key QA issues and to outline the nature and content of a QA plan which would be suitable for SKI, bearing in mind the requirements and recommendations of relevant standards. Emphasis is on issues which are specific to Performance Assessments for deep repositories for radioactive wastes, but consideration is also given to issues which need to be addressed in all large projects. Given the long time over which the performance of a deep repository system must be evaluated, the demonstration that a repository is likely to perform satisfactorily relies on the use of computer-generated model predictions of system performance. This raises particular QA issues which are generally not encountered in other technical areas (for instance, power station operations). The traceability of the arguments used is a key QA issue, as are conceptual model uncertainty, and code verification and validation; these were all included in the consideration of overall uncertainties in the Site-94 project. Additionally, issues which are particularly relevant to SKI include: How QA in a PA fits in with the general QA procedures of the organisation undertaking the work. The relationship between QA as applied by the regulator and the implementor of a repository development programme. Section 2 introduces the discussion of these issues by reviewing the standards and guidance which are available from national and international organisations. This is followed in Section 3 by a review of specific issues which arise from the Site-94 exercise. An outline procedure for managing QA issues in SKI is put forward as a basis for discussion in Section 4. It is hoped that

    Although quality assurance activities have become well established for the hardware found in nuclear medicine little attention has been paid to computer software. This paper outlines some of the problems that exist and indicates some of the solutions presently under development. The major thrust has been towards establishment of programming standards and comprehensive documentation. Some manufacturers have developed installation verification procedures which programmers are urged to use as models for their own programs. Items that tend to cause erroneous results are discussed with the emphasis for error detection and correction being placed on proper education and training of the computer operator. The concept of interchangeable data files or 'software phantoms' for purposes of quality assurance is discussed. (Author)

    The results of research conducted at Pacific Northwest Laboratory (PNL) for the DOE are regularly transferred from the laboratory to the private sector. The principal focus of PNL is on environmental research and waste management technology; other programs of emphasis include molecular science research. The technology transfer process is predicated on Quality to achieve its objectives effectively. Total quality management (TQM) concepts and principles readily apply to the development and translation of new scientific concepts into commercial products. The concept of technology transfer epitomizes the TQM tenet of continuous improvement: always striving for a better way to do things and always satisfying the customer. A successful technology transfer process adds value to society by providing new or enhanced processes, products, and services to government and commercial customers, with a guarantee of product pedigree and process validity. 2 refs

A particular attention is attached thereby both to quality practice proper and to a reliable flow of information amongst all the persons involved. The production and test sequence schedules of the hammer forging plant are illustrated by the example of a forged valve housing for nuclear power plants. These schedules specify not only the forging process in the individual production stages but also the workpiece contour after each working operation, the heat treatment, the furnace charging, and the inspection of finished parts. The formalization of the tests is designed both to promote the customer's trust towards the supplier and to prevent the formal operations involved from hindering further technical development.

    System- and product-related quality assurance measures are completing one another. Certainly it is possible to detect a lot of defects in the single technical document by well controlled product related quality inspections and to avoid the consequences of these defects; but also a not unimportant part of defects and deviations has its origin in system linked deficiencies. The latter can be detected more easily and more securely by means of system related reviews (System audit, Product audit). But also the sole implementation of system related quality assurance measures keeps the danger to get stuck only in formality and to loose all references to the specific characteristics of the product.

    Grid is one of the potential architectures of the coming years to support both the research and the commercial environment. Quality assurance techniques need both to adapt to these new architectures and exploit them to improve its effectiveness. Software quality is a key issue in the Digital Era: Industries as well as Public Administrations devote time to check and verify the quality of ICT products and services supplied. The definition of automatic measurement of quality metrics is a key point for implementing effective QA methods. In this paper we propose a quality certification model, named Grid-based Quality Certification Model (GQCM), that uses automatically calculable metrics to asses the quality of software applications; this model has been developed within the ETICS SSA4 activities and exploit grid technology for full automation of metrics calculation. It is however designed to be generic enough such that it can be implemented using any automatic build and test tool. (Author)

    The credibility of obtained results is ensured by the quality assurance and control. The main requisitions involved in the quality assurance of the laboratory according to the requirements of LVS EN ISO/IEC 17025:2005 are: 1) the use of calibrated equipment only; 2) the regular and long-time use of reference materials in the control of equipment; 3) the estimation of uncertainty sources and determination of uncertainties within the given interval of credibility; 4) the validation and verification. The very important requirement is regular participation in the interlaboratory intercomparison exercises that makes it possible to estimate and find possible error sources and carry out the corrective actions. The measurements of the radioactivity of Cs-137, Co-60, H-3, the natural radioactive nuclides as well as other radionuclides in different environmental (soil, precipitation, different types of water, needles, et al.) samples, and in various radioactive polluted objects are carried out in the Laboratory of Radiation physics. The quality assurance system was implemented in our laboratory in 2000. Since 1999 laboratory is regular participant in the interlaboratory intercomparison exercises, organized by the RISO National Laboratory (Denmark) and IAEA (Vienna). The paper shows the laboratory's system of quality assurance and its implementation. We have the internal quality audit program that takes into account the requirements of LVS EN ISO/IEC 17025: 2005, but the main attention is paid to the intercomparison of the results of analyses of laboratories, their evaluation and interpretation. Only credible and justified results can be the basis for further use in any field, thus making it possible to make legitimate decisions. (Authors)

    Reliability in service essential for many high-technology products fabricated today. This is particularly the case within the nuclear industry. Here defective materials or components may have diastrous consequences to the safety of human beings and the environment. A new concept - Quality Assurance - originates from this industry. The concept implies that all contractors, fabricators and material manufactures involved must prove that the quality control system used, fulfits particular requirements at all manufacturing, inspection and testing stages. These requirement are laid down in two standards issued by the U.S. Atomic Energy Commission and the American Society of Mechanical Engineers. These standards are discussed in the paper. As a manufacturer of steel products for nuclear applications Sandvik has been forced to establish a quality assurance system according to these principles. The Sandvik approach is briefly described with regard to organisation and other major quality assurance activities. Further the education and training of operators and technicians is touched upon. Finally some viewpoints regarding audits performed by customers of steel manufacturers are expressed. (author)

    Quality assurance programs cannot be transferred from one organization to another without attention to existing cultures and traditions. Introduction of quality assurance programs constitutes a significant change and represents a significant impact on the organizational structure and operational mode. Quality assurance professionals are change agents, but do not know how to be effective ones. Quality assurance as a body of knowledge and experience can only become accepted when its practitioners become familiar with their role as change agents. 8 references

    Comprehensive and permanent quality assurance on existing plants places very high requirements on measurement and evaluation technology. The necessary preconditions are often not met, however. By means of stocktaking using an external data registration and evaluation system may provide the basis for the assessment of the object and the existing power station instrumentation. After defining the desired scope and standards for the evaluation process, a specific solution may be produced. 5 figs

    Several studies demonstrated an inverse relationship between cardioverter-defibrillator implantation volume and complication rates, suggesting better outcomes for higher volume centres. However, the association of institutional procedural volume with patient outcomes for permanent pacemaker (PPM) implantation remains less known, especially in decentralized implantation systems. We performed retrospective examination of data on patients undergoing PPM from the German obligatory quality assurance programme (2007-12) to evaluate the relationship of hospital PPM volume (categorized into quintiles of their mean annual volume) with risk-adjusted in-hospital surgical complications (composite of pneumothorax, haemothorax, pericardial effusion, or pocket haematoma, all requiring intervention, or device infection) and pacemaker lead dislocation. Overall 430 416 PPM implantations were documented in 1226 hospitals. Systems included dual (72.8%) and single (25.8%) chamber PPM and cardiac resynchronization therapy (CRT) devices (1.1%). Complications included surgical (0.92%), and ventricular (0.99%), and atrial (1.22%) lead dislocation. Despite an increase in relatively complex procedures (dual chamber, CRT), there was a significant decrease in the procedural and fluoroscopy times and complications from lowest to highest implantation volume quintiles (P for trend <0.0001). The greatest difference was observed between the lowest (1-50 implantations/year-reference group) and the second-lowest (51-90 implantations/year) quintile: surgical complications [odds ratio (OR) 0.69; confidence interval (CI) 0.60-0.78], atrial lead dislocations (OR 0.69; CI 0.59-0.80), and ventricular lead dislocations (OR 0.73; CI 0.63-0.84). Hospital annual PPM volume was directly related to indication-based implantation of relatively more complex PPM and yet inversely with procedural times and rates of early surgical complications and lead dislocations. Thus, our data suggest better performance and lower

    1988-01-01

    This revised Code provides the principles and objectives for the establishment and implementation of quality assurance programmes applied to both the overall and each of the constituent activities associated with a nuclear power plant project. The quality assurance principles enumerated in the present Code can be usefully applied to nuclear facilities other than nuclear power plants. The quality assurance programme encompasses: (1) the activities that are necessary to achieve the appropriate quality of the respective item or service; and (2) the activities that are necessary for verifying that the required quality is achieved and that objective evidence is produced to that effect. Quality assurance is an essential aspect of good management and the quality assurance programme is the main management tool for a disciplined approach to all activities affecting quality, including, where appropriate, verification that each task has been satisfactorily performed and that necessary corrective actions have been implemented. The principles and objectives provided by the Code are applicable by all those responsible for the nuclear power plant, by plant designers, suppliers, architect-engineers, plant constructors, plant operators and other organizations participating in activities affecting quality. The Code is a revision of the previous Code of Practice (1978) on the same subject of interest to regulatory bodies and experts in quality assurance for design, siting and operation of nuclear power plants.

    At present, there is no standard way of evaluating performance characteristics of digital radiography systems. Continuous measurements of performance parameters are necessary in order to obtain images of high quality. Parameters of quality assurance in digital radiography, which can be evaluated with simple, quick methods, are spatial resolution, low-contrast detectability, dynamic range and exposure dose. Spatial resolution was determined by a lead bar pattern, whereas the other parameters were measured by commercially available phantoms. Performance measurements of 10 digital subtraction angiography (DSA) units and one digital radiography system for unsubtracted digital radiography were assessed. From these results, recommendations for performance parameter levels will be discussed. (author)

    The modern concept of quality assurance began to take root in the 50's in Japan. In the rest of the world the demand for quality of products and services might well have arisen through the demise of the craftsman, concurrent with a change in emphasis from quality and workmanship towards economy and output. In the beginning this metamorphosis had its virtues, when rationalisation of production methods benefited both producer and consumer. However, the increasing pressure on production in virtually all sectors of commerce and industry inevitably lead to a trend towards cutting corners, a philosophy not conducive to increasing the standards of quality. The shortage of skilled manpower began to make itself felt at about the same time. The civil construction industry did not remain unscathed

    2013-01-01

    Cooperative groups, of which the Radiation Therapy Oncology Group is one example, conduct national clinical trials that often involve the use of radiation therapy. In preparation for such a trial, the cooperative group prepares a protocol to define the goals of the trial, the rationale for its design, and the details of the treatment procedure to be followed. The Radiological Physics Center (RPC) is one of several quality assurance (QA) offices that is charged with assuring that participating institutions deliver doses that are clinically consistent and comparable. The RPC does this by conducting a variety of independent audits and credentialing processes. The RPC has compiled data showing that credentialing can help institutions comply with the requirements of a cooperative group clinical protocol. Phantom irradiations have been demonstrated to exercise an institution’s procedures for planning and delivering advanced external beam techniques (1–3). Similarly, RPC data indicate that a rapid review of patient treatment records or planning procedures can improve compliance with clinical trials (4). The experiences of the RPC are presented as examples of the contributions that a national clinical trials QA center can make to cooperative group trials. These experiences illustrate the critical need for comprehensive QA to assure that clinical trials are successful and cost-effective. The RPC is supported by grants CA 10953 and CA 81647 from the National Cancer Institute, NIH, DHHS. PMID:24392352

Focus was on the physical aspects of QA and did not address issues that are essentially medical, such as patient selection or prescription of dose. A risk-based QA assessment approach was used. Sample programs for quality control and assurance are included. The use of the Gamma Knife was found to conform to existing standards and guidelines concerning radiation safety and quality control of external beam therapies (shielding, safety reviews, radiation surveys, interlock systems, exposure monitoring, good medical physics practices, etc.) and to be compliant with NRC teletherapy regulations. There are, however, current practices for the Gamma Knife not covered by existing, formalized regulations, standards, or guidelines. These practices have been adopted by Gamma Knife users and continue to be developed with further experience. Some of these have appeared in publications or presentations and are slowly finding their way into recommendations of professional organizations

    In scientific research laboratories it is rarely possible to use quality assurance schemes, developed for large-scale analysis. Instead methods have been developed to control the quality of modest numbers of analytical results by relying on statistical control: Analysis of precision serves...... to detect analytical errors by comparing the a priori precision of the analytical results with the actual variability observed among replicates or duplicates. The method relies on the chi-square distribution to detect excess variability and is quite sensitive even for 5-10 results. Interference control...... serves to detect analytical bias by comparing results obtained by two different analytical methods, each relying on a different detection principle and therefore exhibiting different influence from matrix elements; only 5-10 sets of results are required to establish whether a regression line passes...

    Davison, M.

    1985-01-01

    A number of international bodies have attempted to stimulate wider interest in Quality Assurance in X-ray departments. A major initiative has been taken by WHO with the publication of its recommendations in 1982 under the title Quality Assurance in Diagnostic Radiology, in which they indicated the action that should be taken at various national, professional and local levels. The recommendations of ICRP in Publication 26 point to the need for quality assurance programmes that will obtain optimum diagnostic information at minimum cost and minimum patient dose. ICRU have been considering the need for cost-effective quality assurance programmes and the specification of standards for image quality. The IEC and various manufacturers' organisations have begun to consider the part they can play in setting up quality control procedures. The most active group has been the ISRRT, which has arranged a series of seminars and workshops for radiographers in various parts of the world. Future needs for international support lie in the provision of training programmes, the publication of comparative statistical data and the development of image quality standards. (author)

  3. Reliability assurance programme guidebook for advanced light water reactors

    International Nuclear Information System (INIS)

    2001-12-01

    To facilitate the implementation of reliability assurance programmes (RAP) within future advanced reactor programmes and to ensure that the next generation of commercial nuclear reactors achieves the very high levels of safety, reliability and economy which are expected of them, in 1996, the International Atomic Energy Agency (IAEA) established a task to develop a guidebook for reliability assurance programmes. The draft RAP guidebook was prepared by an expert consultant and was reviewed/modified at an Advisory Group meeting (7-10 April 1997) and at a consults meeting (7-10 October 1997). The programme for the RAP guidebook was reported to and guided by the Technical Working Group on Advanced Technologies for Light Water Reactors (TWG-LWR). This guidebook will demonstrate how the designers and operators of future commercial nuclear plants can exploit the risk, reliability and availability engineering methods and techniques developed over the past two decades to augment existing design and operational nuclear plant decision-making capabilities. This guidebook is intended to provide the necessary understanding, insights and examples of RAP management systems and processes from which a future user can derive his own plant specific reliability assurance programmes. The RAP guidebook is intended to augment, not replace, specific reliability assurance requirements defined by the utility requirements documents and by individual nuclear steam supply system (NSSS) designers. This guidebook draws from utility experience gained during implementation of reliability and availability improvement and risk based management programmes to provide both written and diagrammatic 'how to' guidance which can be followed to assure conformance with the specific requirements outlined by utility requirements documents and in the development of a practical and effective plant specific RAP in any IAEA Member State

  4. Quality assurance considerations in nuclear waste management

    International Nuclear Information System (INIS)

    Delvin, W.L.

    1982-01-01

    Proper use of quality assurance will provide the basis for an effective management control system for nuclear waste management programs. Control is essential for achieving successful programs free from costly losses and failures and for assuring the public and regulators that the environment and health and safety are being protected. The essence of quality assurance is the conscientious use of planned and systematic actions, based on selecting and applying appropriate requirements from an established quality assurance standard. Developing a quality assurance program consists of using knowledge of the technical and managerial aspects of a project to identify and evaluate risks of loss and failure and then to select appropriate quality assurance requirements that will minimize the risks. Those requirements are integrated into the project planning documents and are carried out as specific actions during the life of the project

  12. The IAEA Code of Practice on quality assurance, and quality assurance requirements and practices in Member States

    International Nuclear Information System (INIS)

    Raisic, N.

    1982-01-01

    The IAEA Code of Practice on Quality Assurance for Safety in Nuclear Power Plants and the corresponding Safety Guides are reviewed and compared with quality assurance (QA) practices in the IAEA Member States. The QA requirements stipulated by the Code place on the nuclear power plant owner the responsibility to establish an overall QA programme for the plant. In selecting the QA programme level for specific activities, the Code allows of a flexible approach but does not specify gradation in programme requirements. The Code is placing the burden of quality-achieving and quality-assuring functions on the task-performing organizations, namely the designers, manufacturers, constructors and plant operators. The plant owner provides for the management of the overall QA programme, surveillance of activities and verifications of the effectiveness of the constituent programmes of all project participants through programme audits and evaluations. The Code and the supporting Safety Guides are consistent with existing QA practices in Member States. However, certain differences exist, which are mainly expressed in the different QA functions assigned to the various organizations participating in the overall QA programme. Also, some Member States place more emphasis on redundant verification activities than on quality-achieving functions. Tendencies are also identified to grade the QA requirements in respect of items and activities, in accordance with some pre-established criteria. In an annex to the paper, QA practices in Member States participating in the Agency's Technical Review Committee on Quality Assurance (TRC-QA) are reviewed, indicating their similarities to and differences from the Code

    Today the different kinds of human allografts have the full acceptance for the clinical application for the treatment of a very wide range of indications in many medical disciplines. An essential aspect of this acceptance of these allografts is the complete biological safety, first of all the exclusion of virus contaminations. The German Institute for Cell and Tissue Replacement (DIZG) is functioning as a national tissue bank cooperating with more than 300 hospitals in Germany and Austria. Its profile is determined by the processing of tissue allografts like cortical and cancellous bone, fascia lata, tendon as well as skin, skin substitutes and cultured autologous and allogenic kerytinocytes. DIZG is licensed by the German Federal Institute for Pharmaceuticals and Medical Products and the country health authorities. To ensure that the allografts fulfill the highest quality requirements a controlled and certified quality management system has been established. In accordance with the Good Manufacturing Practice all procedures are perform-ned on the basis of validated methods. All non-vital allografts are sterilized by a chemical sterilisation method with peracetic acid (PAA) that is validated by the Robert Koch Institute, an independent governmental institution, for the inactivation of bacteria, fungi and viruses. The used test viruses are Pseudorabies V, Polio V, Bovine Virusdiarrhoe V, Parvo V, Hepatitis A V, HIV). The DIZG quality management system (QMS) is based on ISO 9001 which is required for institutions that are involved in processing, research and education and is certified by an international auditing body. With this presentation the validation design shall be introduced and the responsibility of regional and national tissue banks for internal and external quality control and quality assurance shall be discussed

    Full Text Available Competitive Intelligence (CI improves the quality of product and service, decision-making and it improves quality of life. However, it has been established that decision makers are not happy about the quality of CI. This is because enterprises fail in quality assurance of CI. It has been concluded that most enterprises are clueless concerning CI quality assurance. Studies that previously attempted to resolve CI quality problem were limited in scope and focused too much on the quality of information than the overall CI quality. The purpose of this study is to propose a conceptual CI quality assurance model which will help in quality assurance of CI. The research was qualitative in nature and used content analysis.

    2015-02-01

    Advances in technical developments of genetic diagnostics for more than 50 years, as well as the fact that human genetic testing is usually performed only once in a lifetime, with additional impact for blood relatives, are determining the extraordinary importance of quality assurance in human genetic testing. Abidance of laws, directives, and guidelines plays a major role. This article aims to present the major laws, directives, and guidelines with respect to quality assurance of human genetic testing, paying careful attention to internal and external quality assurance. The information on quality assurance of human genetic testing was obtained through a web-based search of the web pages that are referred to in this article. Further information was retrieved from publications in the German Society of Human Genetics and through a PubMed-search using term quality + assurance + genetic + diagnostics. The most important laws, directives, and guidelines for quality assurance of human genetic testing are the gene diagnostics law (GenDG), the directive of the Federal Medical Council for quality control of clinical laboratory analysis (RiliBÄK), and the S2K guideline for human genetic diagnostics and counselling. In addition, voluntary accreditation under DIN EN ISO 15189:2013 offers a most recommended contribution towards quality assurance of human genetic testing. Legal restraints on quality assurance of human genetic testing as mentioned in § 5 GenDG are fulfilled once RiliBÄK requirements are followed.

  16. Regulatory viewpoint on nuclear fuel quality assurance

    1976-01-01

    Considerations of the importance of fuel quality and performance to nuclear safety, ''as low reasonably achievable'' release of radioactive materials in reactor effluents, and past fuel performance problems demonstrate the need for strong regulatory input, review and inspection of nuclear fuel quality assurance programs at all levels. Such a regulatory program is being applied in the United States of America by the US Nuclear Regulatory Commission. Quality assurance requirements are contained within government regulations. Guidance on acceptable methods of implementing portions of the quality assurance program is contained within Regulatory Guides and other NRC documents. Fuel supplier quality assurance program descriptions are reviewed as a part of the reactor licensing process. Inspections of reactor licensee control of their fuel vendors as well as direct inspections of fuel vendor quality assurance programs are conducted on a regularly scheduled basis. (author)

    1984-01-01

    The quality assurance programmes of the Japanese industry show some special features, both in the nuclear field and in non-nuclear technology. Among them e.g. the meticulous care given by Japanese workers to their work and duties, and the high training level and skill of employees in the development and other departments. Another important feature is the common practice of Japanese firms, to guarantee lifetime employment to workers and employees. The quality assurance programme for nuclear power plants covers such aspects as basic design features, detailed planning and construction, fuel element fabrication, basic research, licensing and operation. The responsibility for efficient execution of the programmes lies with the administration, the utilities, the suppliers, as well as all other contractors to a project. The tasks to be fulfilled by organisations, firms, etc., are briefly explained. (orig./HSCH) [de

  15. Quality Assurance in Trichiasis Surgery: a methodology

    Science.gov (United States)

    Buchan, John C; Limburg, Hans; Burton, Matthew J

    2013-01-01

    SUMMARY Trachoma remains a significant cause of blindness in many parts of the world. The major route to blindness involves upper lid entropion leading to trachomatous trichiasis (TT) which promotes progressive corneal opacification. The provision of surgery to correct TT in the populations most severely affected is a major challenge for the global effort to eliminate Trachoma blindness by the year 2020. Most attention has been paid to increasing the quantity of TT surgery performed, and large numbers of non-doctor operators have been trained to this end. Surgical audit by those performing TT surgery is not a routine part of any national trachoma control programme, and no effective mechanism exists for identifying surgeons experiencing poor outcomes. We propose a methodology for surgical audit at the level of the individual surgeon based on Lot Quality Assurance. A set number of patients operated on previously for upper eyelid TT are examined to detect the recurrence of TT. The number of recurrent cases found will lead to categorisation of the TT surgeon to either “high recurrence” or “low recurrence” with reasonable confidence. The threshold of unacceptability can be set by individual programmes according to previous local studies of recurrence rates or those from similar settings. Identification of surgeons delivering unacceptably high levels of recurrent TT will guide managers on the need for remedial intervention such as re-training. PMID:20881027

    Anatomic pathology laboratories use several quality assurance tools to detect errors and to improve patient safety. To review some of the anatomic pathology laboratory patient safety quality assurance practices. Different standards and measures in anatomic pathology quality assurance and patient safety were reviewed. Frequency of anatomic pathology laboratory error, variability in the use of specific quality assurance practices, and use of data for error reduction initiatives. Anatomic pathology error frequencies vary according to the detection method used. Based on secondary review, a College of American Pathologists Q-Probes study showed that the mean laboratory error frequency was 6.7%. A College of American Pathologists Q-Tracks study measuring frozen section discrepancy found that laboratories improved the longer they monitored and shared data. There is a lack of standardization across laboratories even for governmentally mandated quality assurance practices, such as cytologic-histologic correlation. The National Institutes of Health funded a consortium of laboratories to benchmark laboratory error frequencies, perform root cause analysis, and design error reduction initiatives, using quality assurance data. Based on the cytologic-histologic correlation process, these laboratories found an aggregate nongynecologic error frequency of 10.8%. Based on gynecologic error data, the laboratory at my institution used Toyota production system processes to lower gynecologic error frequencies and to improve Papanicolaou test metrics. Laboratory quality assurance practices have been used to track error rates, and laboratories are starting to use these data for error reduction initiatives.

    Brachytherapy treatment techniques can provide significant improvement in local control and overall survival, but only when quality assurance can be guaranteed. To establish brachytherapy quality assurance, basic requirements for three predetermined subdivisions of clinical institutions will be forwarded. These are: (1) centers having minimum requirements to provide brachytherapy, (2) intermediate centers such as regional or community hospitals, and (3) optimal centers such as university hospital and cancer centers. This presentation will highlight personnel needs, equipment requirements, academic activities, clinical experience with these systems and proposed quality assurance guidelines

    Defining the Quality Assurance Program for the US Department of Energy Shippingport Station Decommissioning Project (SSDP) was a unique opportunity because this is the first full-sized commercial nuclear power plant to be decommissioned. General Electric Company defined a Quality Assurance Program that provided adequate control, yet was stripped down to the essentials. The Program is designed to provide a flexible degree of monitoring of subcontractor work, built around a core of radiation safety monitoring, detailed planning, inspection and auditing, and operated with a minimum of dedicated personnel. This paper will concentrate on the traditional quality assurance activities, leaving radiation and environmental monitoring for other presentations

  8. Quality assurance for software important to safety

    International Nuclear Information System (INIS)

    2000-01-01

    Software applications play an increasingly relevant role in nuclear power plant systems. This is particularly true of software important to safety used in both: calculations for the design, testing and analysis of nuclear reactor systems (design, engineering and analysis software); and monitoring, control and safety functions as an integral part of the reactor systems (monitoring, control and safety system software). Computer technology is advancing at a fast pace, offering new possibilities in nuclear reactor design, construction, commissioning, operation, maintenance and decommissioning. These advances also present new issues which must be considered both by the utility and by the regulatory organization. Refurbishment of ageing instrumentation and control systems in nuclear power plants and new safety related application areas have emerged, with direct (e.g. interfaces with safety systems) and indirect (e.g. operator intervention) implications for safety. Currently, there exist several international standards and guides on quality assurance for software important to safety. However, none of the existing documents provides comprehensive guidance to the developer, manager and regulator during all phases of the software life-cycle. The present publication was developed taking into account the large amount of available documentation, the rapid development of software systems and the need for updated guidance on h ow to do it . It provides information and guidance for defining and implementing quality assurance programmes covering the entire life-cycle of software important to safety. Expected users are managers, performers and assessors from nuclear utilities, regulatory bodies, suppliers and technical support organizations involved with the development and use of software applied in nuclear power plants

  9. Accidents in radiotherapy: Lack of quality assurance?

    Novotny, J.

    1997-01-01

    About 150 radiological accidents, involving more than 3000 patients with adverse effects, 15 patient's fatalities and about 5000 staff and public exposures have been collected and analysed. Out of 67 analysed accidents in external beam therapy 22% has been caused by wrong calculation of the exposure time or monitor units, 13% by inadequate review of patient's chart, 12% by mistakes in the anatomical area to be treated. The remaining 35% can be attributed to 17 different causes. The most common mistakes in brachytherapy were wrong activities of sources used for treatment (20%), inadequate procedures for placement of sources applicators (14%), mistakes in calculating the treatment time (12%), etc. The direct and contributing causes of radiological accidents have been deduced from each event, when it was possible and categorized into 9 categories: mistakes in procedures (30%), professional mistakes (17%), communication mistakes (15%), lack of training (8.5%), interpretation mistakes (7%), lack of supervision (6%), mistakes in judgement (6%), hardware failures (5%), software and other mistakes (5.5%). Three types of direct and contributing causes responsible for almost 62% of all accidents are directly connected to the quality assurance of treatment. The lessons learnt from the accidents are related to frequencies of direct and contributing factors and show that most of the accident are caused by lack, non-application of quality assurance (QA) procedures or by underestimating of QA procedures. The international system for collection of accidents and dissemination of lessons learnt from the different accidents, proposed by IAEA, can contribute to better practice in many radiotherapy departments. Most of the accidents could have been avoided, had a comprehensive QA programme been established and properly applied in all radiotherapy departments, whatever the size. (author)

    With the introduction of a breast screening programme in the UK, quality assurance in mammography is of paramount importance in assuring optimum imaging performance with low dose. Quality control checks are an essential part of the quality-assurance system. A quality-control programme at a breast screening clinic is described. Daily checks include film sensitometry for X-ray processor control and radiography of a lucite phantom to monitor the consistency of the X-ray machine automatic exposure control. Weekly checks include additional measurements on the performance of the automatic exposure control for different breast thickness and an overall assessment of image quality using a prototype mammography test phantom. The test phantom measures low-contrast sensitivity, high-contrast resolution and small-detail visibility. The results of the quality-control programme are presented with particular attention paid to tolerances and limiting values. (author)

    The purpose of this study was 2-fold. One purpose was to develop an automated, streamlined quality assurance (QA) program for use by multiple centers. The second purpose was to evaluate machine performance over time for multiple centers using linear accelerator (Linac) log files and electronic portal images. The authors sought to evaluate variations in Linac performance to establish as a reference for other centers. The authors developed analytical software tools for a QA program using both log files and electronic portal imaging device (EPID) measurements. The first tool is a general analysis tool which can read and visually represent data in the log file. This tool, which can be used to automatically analyze patient treatment or QA log files, examines the files for Linac deviations which exceed thresholds. The second set of tools consists of a test suite of QA fields, a standard phantom, and software to collect information from the log files on deviations from the expected values. The test suite was designed to focus on the mechanical tests of the Linac to include jaw, MLC, and collimator positions during static, IMRT, and volumetric modulated arc therapy delivery. A consortium of eight institutions delivered the test suite at monthly or weekly intervals on each Linac using a standard phantom. The behavior of various components was analyzed for eight TrueBeam Linacs. For the EPID and trajectory log file analysis, all observed deviations which exceeded established thresholds for Linac behavior resulted in a beam hold off. In the absence of an interlock-triggering event, the maximum observed log file deviations between the expected and actual component positions (such as MLC leaves) varied from less than 1% to 26% of published tolerance thresholds. The maximum and standard deviations of the variations due to gantry sag, collimator angle, jaw position, and MLC positions are presented. Gantry sag among Linacs was 0.336 ± 0.072 mm.

    Malignant tumours are the second largest cause of death in Europe. Colorectal cancer takes second place within this group and is responsible for every eighth tumour-related death. Surgical quality assurance requires a prospective observational study, any different type of study is not possible. A complete recording of all treated patients is a prerequisite for quality assurance. Currently, there are quality assurance programmes in Sweden, Norway, Denmark, Great Britain, Spain, Belgium, the Netherlands as well as the multinational study for patients from Germany, Poland and Italy. These projects deliver comprehensive information regarding the treatment of colorectal cancer. However, this information is deeply rooted in the organisation of the health-care system in the given country and is not easily transferable into international settings. Also, an interpretation of the collected data is often possible only within the given health-care system. First, unified initial diagnostics is a prerequisite for quality assurance -  for the local extent and exclusion / confirmation of distant metastases. Until these criteria are unified, any comparison is limited, including a comparison of survival. Second, quality-of-life is not recorded in any of the current projects. Third, the main focus of a quality assurance project must be on therapy-dependent factors. The most sensible method of quality control remains within the connection of preoperative diagnostics (estimate of a best-case scenario), the surgical technique (the actual result) and a standardised pathological examination (evaluation of the actual result). These parameters can be recorded and compared within a quality assurance project regardless of the limitations of the national health-care systems. There is no alternative to a unified diagnostics model and unified histopathological evaluation, a complete picture of treatment quality is also not possible without systematic analysis of the quality of life.

    Radiotherapy is a modality of choice for treatment of malignant diseases. Linear accelerators are the most common devices for implementing external radiation therapy. Taking into account the fact during the treatment, healthy tissue will inevitably be exposed to ionizing radiation, predicted dose in each radiotherapy case should be delivered with the greatest possible accuracy. Medical requirement for quality treatment achieving means as mach as possible dose into volume of interest and the greatest possible healthy tissue protection. From radiation protection point of view, occupational exposure of the staff involved in radiotherapy process should be minimized. To be able to reach it, consistent adherence to the Quality Assurance Programme is necessary. It should be in accordance with higher national and international protocols, because they give guidelines on the necessary standards, procedures, processes, resources and responsibilities that should be defined in structuring the overall radiotherapy quality management. As a part of this Master thesis, quality management as well as Quality Assurance Programme that is necessary to be applied in each radiotherapy center have been prepared. Mandatory dosimetry measurements included in the internal recommendations are also emphasized. Measurement results and external audit by IAEA indicated high accuracy and quality radiotherapy dose delivering in Macedonia. Based on the measurements and analysis, the aim of this Master thesis is offering a Quality Assurance Protocol for external beam radiotherapy that can be used on the national level in Republic of Macedonia.

  15. Current conceptions of industrial quality assurance

    International Nuclear Information System (INIS)

    Zeller, H.

    1978-01-01

    In the electrical engineering industry quality assurance is mainly oriented in accordance with the customers', users', and consumers' requirements concerning the quality of products (including reliability). These requirements are as manifold as the range of products itself. They do not only comprise functional criteria, but also safety against malfunctions, bodily injury or property damage. Quality assurance is embedded in the overall activities of a company; the peripheral conditions, such as organization, profitability, qualification, and responsibility of staff have to be considered. Thus, quality assurance in the electrical engineering industry proceeds in efficient systems which are adapted to the individual forms of production. These systems may include planning, testing, feedback of quality data, statistical procedures, costs and profitability. Their obvious interaction is based on the system of coordinates of integrated quality control. The paper will illustrate the basic features of this interaction by reference to various examples.

    Full text:The lecture aims to present contemporary view of quality assurance in X-Ray diagnosis and its practical realization in Bulgaria. In the lecture the concepts of quality assurance, quality control and clinical audit will be defined and their scope will be considered. An answer of the following questions will be given: why is it necessary to determine the dose of patient in X-ray studies, what is the reference dose level and how it is used for dosimetric quantity which characterized the patient's exposure in X-ray, mammography and CT scans and how they are measured, who conducted the measurement and how to keep the records, what are the variations of doses in identical tests and what defines them? The findings from a national survey of doses in diagnostic radiology, conducted in 2008-2009 and the developed new national reference levels will be presented. The main findings of the first tests of radiological equipment and the future role of quality control as well as the concept of conducting clinical audit and its role in quality assurance are also presented. Quality assurance of the diagnostic process with minimal exposure of patients is a strategic goal whose realization requires understanding, organization and practical action, both nationally and in every hospital. To achieve this the important role of education and training of physicians, radiological technicians and medical physicists is enhanced

    Purpose: The purpose of this study was 2-fold. One purpose was to develop an automated, streamlined quality assurance (QA) program for use by multiple centers. The second purpose was to evaluate machine performance over time for multiple centers using linear accelerator (Linac) log files and electronic portal images. The authors sought to evaluate variations in Linac performance to establish as a reference for other centers. Methods: The authors developed analytical software tools for a QA program using both log files and electronic portal imaging device (EPID) measurements. The first tool is a general analysis tool which can read and visually represent data in the log file. This tool, which can be used to automatically analyze patient treatment or QA log files, examines the files for Linac deviations which exceed thresholds. The second set of tools consists of a test suite of QA fields, a standard phantom, and software to collect information from the log files on deviations from the expected values. The test suite was designed to focus on the mechanical tests of the Linac to include jaw, MLC, and collimator positions during static, IMRT, and volumetric modulated arc therapy delivery. A consortium of eight institutions delivered the test suite at monthly or weekly intervals on each Linac using a standard phantom. The behavior of various components was analyzed for eight TrueBeam Linacs. Results: For the EPID and trajectory log file analysis, all observed deviations which exceeded established thresholds for Linac behavior resulted in a beam hold off. In the absence of an interlock-triggering event, the maximum observed log file deviations between the expected and actual component positions (such as MLC leaves) varied from less than 1% to 26% of published tolerance thresholds. The maximum and standard deviations of the variations due to gantry sag, collimator angle, jaw position, and MLC positions are presented. Gantry sag among Linacs was 0.336 ± 0.072 mm. The

    2001-01-01

    Since Uruguay did not have an study on X-ray equipment, students of Radiation Protection course (RP) made this field work throughout the country. The objective is to obtain information on the number and kind of X-ray radiodiagnostic equipment. Some of the results are: there are 666 radiodiagnostic equipment. The ratio of population to equipment is 4.515 to 1 in the capital and the mean rate in the rest of the country is 4.383 to one, with a minimum of 1.707 and a maximum of 8.220. The Public Health Ministry (MSP) and the Instituciones de Asistencia Medica Colectiva (a kind of private heath assurance) (IAMC) have less equipment in the capital than in the rest of the country. The 37% of the capital population receives assistance through the IAMC , with a 42.5 % of the equipment. Uruguay except the capital has 18 districts and 17 computed tomography equipment, from which only 3 belong to the MSP. Five districts do not have any. In Montevideo, there are 11.500 females over forty years of age per X-ray mammography equipment, and this relation in the rest of the country is 13.900. There are 21 X-ray Interventional radiology equipment, 16 of them are in the capital. Is from relating the radiodiagnostic equipment, the population and the procedures, that quality assistance indicators emerge. This owns high importance on the way to create a RP National Programme.

    Quality assurance programs have been part of the nuclear utility management process since the publication of the draft of 10CFR50 Appendix B in the late 1960s. The unwritten operational philosophy of nuclear quality assurance organizations focused on compliance with federal regulations. Adverse experiences, including operational events and extended shutdowns, prompted the gradual adoption of isolated practices extending beyond compliance orientation. These practices have an orientation that accommodates a definition of quality, a perspective of the role of nuclear quality assurance organizations in the overall concept of defense-in-depth, a definition of the segments of the nuclear quality assurance mission, and recent advances in the understanding of self-assessment. Observation of these practices at various nuclear utilities resulted in a syntheses of practices and approaches into a coherent quality-oriented nuclear quality assurance operating philosophy that is not totally adopted at any one utility

    2001-01-01

    One of the applications of radioisotopes in industry is non destructive testing (NDT) where the industrial radiography sources are often transported in public domain for site radiography. About 1100 cameras are deployed in our country. This transport of the sources can lead to significant radiological impact in case of accidents unless all precautions are taken. It is, therefore, required to have a systematic programme of controls and inspections in the transport of radioactive source. In this paper, we discuss the quality assurance programme that should be applied in various stages of the transport of radioactive sources to ensure a safe transport and prompt delivery of the radioactive consignment at its destination.

    A presentation is given of some characteristics of the International Electrotechnical Commission (IEC). This is followed by a short discussion of general aspects of quality assurance in the diagnostic department. From this discussion it becomes apparent to which aspects of quality assurance IEC can contribute. Within that framework a working group of Sub-Committee 62 is at present active in developing a standard on quality assurance for diagnostic X-ray systems. The standard will contain a set of constancy tests that is claimed to allow a balanced quality assurance programme. The democratic procedure of IEC should guarantee that the proposed standard gains wide acceptance. (author)

    In Uruguay, breast cancer incidence is 76.41 per 100.000, and death rate is 25.22 per 100.000. Since 1998, there is a National Programme of breast cancer early detection for females over forty years of age. We studied the state of the mammography facilities throughout the country. There are 657.000 female over forty and 51 mammography X-ray equipment. The Programme includes 2 mammography X-ray equipment in mobile units in the capital and 18 in hospitals all around the country. There are taken 120.000 mammographic exams per year, 15.000 of them belong to women who had participated in the Programme. We found that no mammography facility has established Quality Assurance Programmes. Despite the results of this study showed that is suitable the number and age of the mammography X-ray equipment, the lack of Quality Assurance Programmes will produce, in a short time, a negative cost-benefit balance. The consequences will be serious social, human an economical damages. (author)

    Intensive care medicine (ICM) is characterized by a high degree of complexity and requires intense communication and collaboration on interdisciplinary and multiprofessional levels. In order to achieve good quality of care in this environment and to prevent errors, a proactive quality and error management as well as a structured quality assurance system are essential. Since the early 1990s, German intensive care societies have developed concepts for quality management and assurance in ICM. In 2006, intensive care networks were founded in different states to support the implementation of evidence-based knowledge into clinical routine and to improve medical outcome, efficacy, and efficiency in ICM. Current instruments and concepts of quality assurance in German ICM include core intensive care data from the data registry DIVI REVERSI, quality indicators, peer review in intensive care, IQM peer review, and various certification processes. The first version of German ICM quality indicators was published in 2010 by an interdisciplinary and interprofessional expert commission. Key figures, indicators, and national benchmarks are intended to describe the quality of structures, processes, and outcomes in intensive care. Many of the quality assurance tools have proved to be useful in clinical practice, but nationwide implementation still can be improved.

    Due to the close connection between the German Atomic Energy Law and the nuclear control regulations, quality systems in nuclear engineering have taken on a special form. Quality assurance systems as a stipulated organisation of structure and procedure to assure quality have implications for the organisation of the electric supply company at the planning, erection and commissioning stage and for the organisation of the nuclear power station facility. To supervise the application and effectiveness of the stipulated organisation of structure and procedure internally and externally among contractors, special organisation units have been set up at the plant suppliers, manufactures, electric supply companies and nuclear power station facilities, which in the electric supply field go by the name of Quality Assurance Supervision.

    An emphasis on preventive rather than reactive management is key to an efficient construction management operation. Development of contingency plans to deal with unexpected adverse conditions, e.g., brine pockets during mining operations, are an integral part of the management program to ensure project safety, quality, cost, schedule and environmental objectives are met. A viable quality assurance program with active management support will optimize management effectiveness in reaching project goals. With adequate planning and perceptive application of the proper management controls, Quality Assurance becomes an essential ingredient for efficiently managing a job because it has been built into the management system rather than being an uninvolved peripheral entity. 6 references, 3 figures

    The author proposes that multilayer Quality Control is burdensome and ineffective. He proposes that the earlier approaches of having responsible field engineers back on the job site instead of at a home office be reinitiated to speed up necessary design changes and hold down costs. It is then the job of the quality control personnel to assure that the field engineer is doing his job. The idea of using the reactor start-up process as part of the quality assurance program is also proposed. Also discussed is the idea of Operating License Contracts or One Step Licensing Approach

    2015-04-01

    The Helmholtz Research School MICMoR (Mechanisms and Interactions of Climate Change in Mountain Regions) offers a structured graduate programme for doctoral students in the field of climate change research. It is hosted by the Institute of Meteorology and Climate Research (KIT/IMK-IFU) in Garmisch-Partenkirchen, in collaboration with 7 Bavarian partner universities and research institutions. Hence, MICMoR brings together a considerably large network with currently 20 doctoral students and 55 scientists. MICMoR offers scientific and professional skills training, provides a state-of-the-art supervision concept, and fosters international exchange and interdisciplinary collaboration. In order to develop and advance its programme, MICMoR has committed itself to a self-imposed mid-term review in its third year, to monitor to which extent its original objectives have been reached, and to explore and identify where MICMoR has room for improvement. The evaluation especially focused on recruitment, supervision, training, networking and cooperation. Carried out by an external expert (Beate Scholz from scholz ctc), the evaluation was based on a mixed methods approach, i.e. combining a quantitative survey involving all doctoral candidates as well as their supervisors and focus groups with different MICMoR stakeholders. The evaluation has brought forward some highly interesting results, pinpointing challenges and opportunities of setting up a structured doctoral programme. Overall, the evaluation proved to be a useful tool for evidence-based programme and policy planning, and demonstrated a high level of satisfaction of supervisors and fellows. Supervision, with facets ranging from disciplinary feedback to career advice, is demanding and requires strong commitment and adequate human resources development by all parties involved. Thus, MICMoR plans to offer mentor coaching and calls on supervisors and mentors to form a community of learners with their doctoral students. To

    1981-01-01

    In a first part this lectures will present a survey on nuclear power production and plant performance in the Western World and discuss key parameters such as load factors and non-availability. Some main reasons for reliable performance of nuclear power plants are given. The second part of this lecture deals with the question how quality assurance and quality control measures do directly influence plant reliability, availability and, thus, economy. Derived from worldwide experience gained from operating nuclear power plants, it may be concluded that the implementation of an overall quality assurance programme does not only satisfy safety requirements set forth by the nuclear regulatory bodies, but has also a considerable impact on plant reliability and availability. A positive effect on these figures will be achieved if the established quality assurance programme provides for a coordinated approach to all activities affecting quality. It is discussed how the quality of a product should be controlled and what kind of quality assurance measures by performed examples are given to demonstrate that the expenditure for maintenance work on components will decrease if planned and systematic quality assurance actions have been implemented during all procurement stages.

    TOSCA was an EU-Commission supported international research project designed to develop telescreening services in diabetic retinopathy and glaucoma. This paper describes the quality assurance methods developed for the diabetic retinopathy telescreening service within the TOSCA project. The study was performed in 1895 patients with diabetes between 2000 and 2002 at diabetic retinopathy screening sites in five European countries. Data were analysed centrally. Patients attending each clinic's diabetic retinopathy screening service received standardized retinal photography. The images and associated data were transferred electronically to a remote location for grading. Each photographer uploading images and each grader downloading images for assessment was controlled by a systematic quality management approach. The quality assurance measures defined were image quality, intragrader reliability. A cockpit chart was developed for the management and presentation of relevant results and quality measures. For the intragrader reliability tests, 10% of the images were processed for a second grading. An algorithm for calculating differences between repeated gradings was developed. The assessment of image quality for the different sites showed that only 0-0.7% were unassessable. One hundred per cent agreement for both gradings was achieved in 50-85% of graded cases, depending on site and grader, and an agreement better than 95% in 71-100% of cases. A telemedicine-supported quality assurance process is practical and advantageous. The cockpit charts have proven to be useful tools when monitoring the performance of a telescreening service. Grader feedback showed high satisfaction with the quality assurance process.

    Jacky, J.; Kalet, I.

    1987-01-01

    The authors recommend quality assurance procedures for radiation therapy software. Software quality assurance deals with preventing, detecting and repairing programming errors. Error detection difficulties are most severe in computer-based control systems, for example therapy machine control systems, because it may be impossible for users to confirm correct operation while treatments are in progress, or to intervene if things go wrong. Software quality assurance techniques observed in other industries in which public safety is at risk are reviewed. In some of these industries software must be approved or certified before it can be used. Approval is subject to technical reviews and audits by experts other than the program authors. The main obstacles to adoption of these techniques in the radiation therapy field are costs, lack of familiarity and doubts regarding efficacy. 18 refs

    The first part of the lecture deals with the Quality Assurance system on the construction site in general. Basic site-related problems during contract implementation and the QA system requirements resulting from them are presented. The compilation of these requirements in a QA program and its inclusion in the site manual in written form are explained. Site organization, personnel qualification and procedures are referred to. Whereas the first part shows what is to be done, the second part shows how it can be put into practice on the site. All the essential points for the assurance of quality are addressed. They include, e.g., review of documents, incoming goods control, in-process surveillance, store controls, identification of components and systems, dealing with changes and deviations, documentation control and audits. By means of examples taken form practice the necessity of a well-functioning QA system, and the importance of quality-assuring measures on the site are pointed out. (orig.)

    In high-consequence engineering organizations, such as Sandia, quality assurance may be heavily dependent on staff competency. Competency-dependent quality assurance models are at risk when the environment changes, as it has with increasing attrition rates, budget and schedule cuts, and competing program priorities. Risks in Sandia's competency-dependent culture can be mitigated through changes to hiring, training, and customer engagement approaches to manage people, partners, and products. Sandia's technical quality engineering organization has been able to mitigate corporate-level risks by driving changes that benefit all departments, and in doing so has assured Sandia's commitment to excellence in high-consequence engineering and national service.

    It has been proven that the bad quality of products, equipment, installations, and services is not due to the lack of tests, experiments and verifications. The main causes are associated with insufficient organization of the activities that have influence on the quality. The garantee of quality is conceptualized as an appropriate instrument composed of normalized criteria initially in advanced technologies. Such as nuclear science and aerospace technology. However, with the appropriate modifications it can be applied to conventional technologies

  13. Statistical process control for radiotherapy quality assurance

    Pawlicki, Todd; Whitaker, Matthew; Boyer, Arthur L.

    2005-01-01

    Every quality assurance process uncovers random and systematic errors. These errors typically consist of many small random errors and a very few number of large errors that dominate the result. Quality assurance practices in radiotherapy do not adequately differentiate between these two sources of error. The ability to separate these types of errors would allow the dominant source(s) of error to be efficiently detected and addressed. In this work, statistical process control is applied to quality assurance in radiotherapy for the purpose of setting action thresholds that differentiate between random and systematic errors. The theoretical development and implementation of process behavior charts are described. We report on a pilot project is which these techniques are applied to daily output and flatness/symmetry quality assurance for a 10 MV photon beam in our department. This clinical case was followed over 52 days. As part of our investigation, we found that action thresholds set using process behavior charts were able to identify systematic changes in our daily quality assurance process. This is in contrast to action thresholds set using the standard deviation, which did not identify the same systematic changes in the process. The process behavior thresholds calculated from a subset of the data detected a 2% change in the process whereas with a standard deviation calculation, no change was detected. Medical physicists must make decisions on quality assurance data as it is acquired. Process behavior charts help decide when to take action and when to acquire more data before making a change in the process

    Even when the basic requirements for a Quality Assurance Program are delineated in documents such as the Code of Federal Regulations or Standards like ANSI N 45. 2, the way in which these requirements are put into practice is very dependent on the organization to which they are applied. So, in order to approach accurately the Quality Assurance practice and experience in Spain, the legal and industrial scenario must be considered. We are trying to present an outlook of the Spanish Energy Plan, Regulations and Nuclear Industry. (orig.)

    This paper describes the programmes and approaches that are to be considered in developing and introducing quality assurance and quality control procedures in individual monitoring services. Quality assurance and quality control in individual monitoring services are essential to maintain quality and are of increasing importance in order to meet the requirements of national regulations and international standards and guidelines. It is recommended here that all organisations offering individual monitoring services should run their services based on the principles of Quality System as given in the European Standard EN45001 and maintain a property resources QA/QC programme as an integral part of their operations. All aspects of QA/QC in individual monitoring services starting from the initial selection, installation, calibration, and operation to the final products including dose reporting, dose record keeping, dealing with customers' complaints and product liability issues have been discussed.

    The successful Chief Executive Officer (CEO) will have recognized the benefits of, and have implemented, a total quality assurance program. The quality assurance program will be adequately defined in policies and procedures such that managers and supervisors of each organizational element understand their primary and supporting roles in carrying out an effective quality assurance program. The traditional practice of having all quality assurance activities reside in a quality assurance organization will have been cast aside. Instead, the quality assurance activities necessary to achieve and assure the quality of the desired end product will have been defined and assigned to responsible organization elements. The quality assurance organization's primary role will be to define the total quality assurance program, insure that the achieving and assuring functions are assigned in policies and procedures, conduct training necessary to have management and supervisors understand the total quality assurance program, measure the effectiveness of the program and feedback measurement data for improvements in the program. The successful CEO will have implemented a quality assurance program that provides for a graded approach for application of the program based upon the importance of the intended use of the product or service. The successful CEO will rely heavily on the scheduled progress reports and assessments to measure the pulse of his organization's successes and improvement needs. This paper will describe suggested approaches for the Quality Assurance Manager to implement a quality assurance program which results in his corporation's CEO being a supporter of and a driving force in the implementation of the quality assurance program

    Full Text Available Product and service quality, effective process management, continuous improvement and innovation are some essential conditions for making a successful business. They are often emphasised by managers of successful organizations, by authors of professional and scientific papers and even by politicians and journalists. Quality management standards and models, such as ISO 9001 and EFQM model appeared in assistance to the needs of organisations to assure stable product and service quality, to improve it and to make the production process and its supporting processes effective. It has been 28 years since the standard ISO 9001 appeared. Now it is the most widely spread global standard implemented in more than 1.100.000 organizations worldwide. If quality management was proved to be an important approach to make organizations operate better and thus to contribute to well-being of the society, it would be expected that it is somehow included in our regular school programmes on all the levels. We expect that learning and living quality approaches in childhood and youth would be the least costly way to improve the culture of quality in the society and to implement it in our organizations as well. The paper gives some insight in the situation by searching for quality management related programmes and approaches in our primary, secondary and tertiary school programmes. The purpose of this paper is only to highlight the issue of teaching for quality in our regular education programmes – just to become aware of it and to find some improvement opportunities. There should be still some more detailed research on this topic to give strong suggestions.

    Sonography is a subjective diagnostic method which is highly dependent on the experience of the operator and the equipment quality which requires real-time adjustments. Breast screening examination currently consists of clinical examination and mammography. Breast sonography, either supplementary to mammography or independently, is indicated for the dense breast, especially in younger women. Breast sonography is especially applicable for Korean women because of the denser breast parenchyma and the approximately 10-year younger incidence rate of breast cancer of Korean women compared to western women. To avoid unnecessary breast biopsy because of the high rate of false positive lesions in breast parenchyma, which is different from other body organs such as the liver or the kidney, a quality assurance program for breast sonography is essential. The quality assurance of breast ultrasound involves quality assurance of the equipment, imaging display and acquisition of clinical images, personnel qualifications and other aspects such as unification of lexicon, guideline of diagnostic examination and reporting system; US BI-RAD reporting system, assessment items and organization, education program, medical audit, certification issues, and medicolegal issues. A breast sonographic quality assurance system should be established before a scheme to initiate governmental medical insurance for breast sonography

  4. Quality Assurance in the Presence of Variability

    Science.gov (United States)

    Lauenroth, Kim; Metzger, Andreas; Pohl, Klaus

    Software Product Line Engineering (SPLE) is a reuse-driven development paradigm that has been applied successfully in information system engineering and other domains. Quality assurance of the reusable artifacts of the product line (e.g. requirements, design, and code artifacts) is essential for successful product line engineering. As those artifacts are reused in several products, a defect in a reusable artifact can affect several products of the product line. A central challenge for quality assurance in product line engineering is how to consider product line variability. Since the reusable artifacts contain variability, quality assurance techniques from single-system engineering cannot directly be applied to those artifacts. Therefore, different strategies and techniques have been developed for quality assurance in the presence of variability. In this chapter, we describe those strategies and discuss in more detail one of those strategies, the so called comprehensive strategy. The comprehensive strategy aims at checking the quality of all possible products of the product line and thus offers the highest benefits, since it is able to uncover defects in all possible products of the product line. However, the central challenge for applying the comprehensive strategy is the complexity that results from the product line variability and the large number of potential products of a product line. In this chapter, we present one concrete technique that we have developed to implement the comprehensive strategy that addresses this challenge. The technique is based on model checking technology and allows for a comprehensive verification of domain artifacts against temporal logic properties.

    DOE Order 5700.6C, Quality Assurance, stipulates QA requirements for all DOE activities. This order is now codified as 10CFR830.120, Nuclear Safety Management, Quality Assurance Requirements, which is applicable to DOE nuclear facilities. A Quality Assurance Management Plan (QAMP) was developed by the Health Physics Operations Group (ESH-1) at Los Alamos National Laboratory (LANL). The goal of the ESH-1 QAMP is to ensure that operational radiation protection activities meet the criteria outlined in DOE Order 5700.6C, DOE-ER-STD-6001-92 and 10CFR830.120. The ten required elements are QA Program, Personal Training and Qualifications, Quality Improvement, Documents and Records, Work Processes, Design, Procurement, Inspection and Acceptance Testing, Management Assessment and Independent Assessment. The QAMP has been useful for the development of QAMPs at nuclear facilities and has helped ensure uniformity of institutional requirements where Health Physics services are deployed to facilities. To implement a subset of QAMP requirements, a Quality Assurance Self-Evaluation Program (QASE) was established. This program provides a novel self-audit mechanism for the formal identification and correction of non-conforming items related to Operational Health Physics. Additionally, the QASE is a useful management tool for Radiological Control Technician Supervisors and staff and provides a tracking mechanism for ongoing problem areas. Data have been Collected for two calendar years on a number of concerns that fall into four general categories: radiological posting and labeling, instrumentation, monitoring requirements, and radiological documents/records

    This questionnaire forms the basis of the quality assurance (QA) programme for the UK randomized Phase III study of the Stanford V regimen versus ABVD for treatment of advanced Hodgkin's disease to assess differences between participating centres in treatment planning and delivery of involved-field radiotherapy for Hodgkin's lymphoma The questionnaire, which was circulated amongst 42 participating centres, consisted of seven sections: target volume definition and dose prescription; critical structures; patient positioning and irradiation techniques; planning; dose calculation; verification; and future developments The results are based on 25 responses. One-third plan using CT alone, one-third use solely the simulator and the rest individualize, depending on disease site. Eleven centres determine a dose distribution for each patient. Technique depends on disease site and whether CT or simulator planning is employed. Most departments apply isocentric techniques and use immobilization and customized shielding. In vivo dosimetry is performed in 7 centres and treatment verification occurs in 24 hospitals. In conclusion, the planning and delivery of treatment for lymphoma patients varies across the country. Conventional planning is still widespread but most centres are moving to CT-based planning and virtual simulation with extended use of immobilization, customized shielding and compensation.

  7. Quality assurance tracking and trending system (QATTS)

    Anderson, W.J.

    1987-01-01

    In 1984, The Philadelphia Electric Company (PECo) Quality Assurance (QA) Division recognized a need to modify the existing quality finding tracking program to generate a nuclear trending program that could detect trends of PECo-initiated findings that were not detectable to a day-to-day observer. Before 1984, each quality organization in PECo had a separate tracking system. An adequate quality trending program demanded that all findings be tracked in a common data base. The Quality Assurance Tracking and Trending System (QATTS) is divided into two parts, an on-line subsystem that provides access to QATTS data via corporate computer data screens and a reports and graphics subsystem that connects commercially available reports and graphic software computer packages to the QATTS data base. The QATTS can be accessed from any terminal connected to the main frame computer at PECo headquarters. The paper discusses the tracking system, report generation, responsible organization commitment tracking system (ROCT), and trending program

    The Quality Assurance policy of the US Environmental Protection Agency (EPA) stipulates that every project involving environmentally related monitoring, measurements, and data collection activities must have a written and approved quality assurance project plan (QAPjP). A QAPjP is a written document which presents, in specific terms, the policies, organizations, objectives, functional activities, and the quality assurance/quality control activities designed to achieve the quality goals for data collection. In the research studies involving novel or non-routine measurements that use unvalidated methods, measurement quality goals are often difficult or impossible to specify at the beginning of the project for which a QAPjP must be written. Furthermore, it may not be possible for the QAPjP reviewers to evaluate the reasonableness of these goals without initial information about the system under study. For the project to evaluate chlorofluorocarbon for recycling from domestic refrigerators, the QAPjP incorporated standard analytical techniques used by industry. These techniques did not provide accuracy and precision or other validation information. For the initial version of the QAPjP, measurement quality goals were assigned based on limited experience. Quality assurance support was called upon to evaluate the performance of the measurement system for this project through a series of audits. The performance evaluation audits necessitated designing novel audit materials and sample delivery techniques. Continued interaction is necessary between the project and QA teams to permit evolution of reasonable data quality indicators for meaningful assessment of data quality. By treating the QAPjP as a living document that is updated and amended as more knowledge of a system is obtained, AQ becomes an integral part of the research program. This results in a greater understanding of the system under study

In the present article, the term quality in the management of diseases is defined and the system of total quality management discussed at the levels structure, process, and results. For its application, parameters of quality measurement in the form of standards, criteria, and characteristic values are necessary and must be laid down by a team of experts on the basis of subjective experience and/or results in the literature. Practical quality assurance takes place not only within a clinic but also externally by comparison with other centers. Data collection and evaluation requires high-performance software that will be continuously improved, expanded, and adapted to current needs during regular meetings between the various users. (orig.)

    Biscan, R.; Fifnja, I.; Kavsek, D.

    2012-01-01

    International standards from nuclear power plant operation area are being frequently upgraded and revised in accordance with the continuous improvement philosophy. This philosophy applies also to the area of Quality Assurance, which has also undergone significant improvement since the early 1950s. Besides just nuclear industry, there are also other international quality standards that are being continuously developed and revised, bringing needs for upgrades also in the nuclear application. Since the beginning of Krsko NPP construction, the overall Quality Assurance program and its applicable procedures were in place to assure that all planned and systematic actions necessary to provide adequate confidence that an item or service will satisfy given requirements to quality, are in place. The overall requirements for quality as one of the major objectives for Krsko NPP operation are also set forth in the Updated Safety Analyses Report, the document that serves as a base for operating license. During more than 30 years of Krsko NPP operation, the quality requirements and related documents were revised and upgraded in several attempts. The latest revision 6 of QD-1, Quality Assurance Plan was issued during the year 2011. The bases for the revision were: Changes of the Slovenian regulatory requirements (ZVISJV, JV5, JV9?), Changes of Krsko NPP licensing documents (USAR section 13?), SNSA inspection requirements, Changes of international standards (IAEA, ISO?), Conclusions of first PSR, Implementation of ISO standards in Krsko NPP (ISO14001, ISO17025), Changes of plant procedures, etc. One of the most obvious changes was the enlargement of the QA Plan scope to cover interdisciplinary areas defined in the plant management program MD-1, such as Safety culture, Self-assessment, Human performance, Industrial Safety etc. The attachment of the QA Plan defining relationships between certain standards was also updated to provide matrix for better correlation of requirements of

  12. Quality assurance for electronic portal imaging devices

    Shalev, S.; Rajapakshe, R.; Gluhchev, G.; Luchka, K.

    1997-01-01

    Electronic portal imaging devices (EPIDS) are assuming an ever-increasing role in the verification of radiation treatment accuracy. They are used both in a passive capacity, for the determination of field displacement distributions (''setup errors''), and also in an active role whereby the patient setup is corrected on the basis of electronic portal images. In spite of their potential impact on the precision of patient treatment, there are few quality assurance procedures available, and most of the EPIDS in clinical use are subject, at best, to only perfunctory quality assurance. The goals of this work are (a) to develop an objective and reproducible test for EPID image quality on the factory floor and during installation of the EPID on site; (b) to provide the user with a simple and accurate tool for acceptance, commissioning, and routine quality control; and (c) to initiate regional, national and international collaboration in the implementation of standardized, objective, and automated quality assurance procedures. To this end we have developed an automated test in which a simple test object is imaged daily, and the spatial and contrast resolution of the EPID are automatically evaluated in terms of ''acceptable'', ''warning'' and ''stop'' criteria. Our experience over two years shows the test to be highly sensitive, reproducible, and inexpensive in time and effort. Inter-institutional trials are under way in Canada, US and Europe which indicate large variations in EPID image quality from one EPID to another, and from one center to another. We expect the new standardized quality assurance procedure to lead to improved, and consistent image quality, increased operator acceptance of the technology, and agreement on uniform standards by equipment suppliers and health care agencies.

    2002-01-01

    The European Society for Therapeutic Radiology and Oncology (ESTRO) Quality Assurance network for radiotherapy (EQUAL) has been set up in 1998 for European countries. This TLD postal dose assurance service addresses to photon and electron beam checks in reference and non-reference conditions and is successful with more than 440 radiotherapy centres and 1,656 beams checked. Dosimetric problems in the beam calibration, errors in beam data used as input to the treatment planning system (TPS), or uncertainties in the algorithms used in the TPS can be detected in the EQUAL audit. The EQUAL reference dosimetry is linked to the IAEA dosimetry laboratory and to the Radiological Physics Center (RPC) dosimetry laboratory by periodic intercomparisons. The absorbed doses to water in photon and electron beams, measured with the ionization chambers, are determined following the procedure described in the new IAEA TRS-398 International Code of Practice for dosimetry based on standards of absorbed dose to water. The participating centres are instructed to irradiate the TLD (LiF) capsules to a dose of 2 Gy according to the calculations given by the Treatment Planning System used in clinical routine. For photon beams, the EQUAL checks four dosimetric parameters: the reference beam output, the percentage depth doses, the beam output variation for open and wedged fields and the wedge transmission factor. In electron TLD audits, beam outputs are checked for 4 different field sizes. EQUAL has checked 440 radiotherapy centres corresponding to 1,656 beams (1009 photon beams and 574 electrons beams and 73 photon beams shaped by multileaf collimators). The results from measurements at the reference point are very good both for photon and electron beams. For photons, the rates of deviation (vertical bar d vertical bar D measured- D stated ) x 100 / D stated ) larger than 5% which have been observed are respectively of 2.6% for the beam output variation and 3.5% for the wedge transmission

    2002-01-01

    Due to the modifications of components, to unexpected breakage of elements or to electronic dysfunctions, the performance of radiotherapy machines may decrease with age. Quality Assurance procedures and maintenance program are necessary to guarantee the performances. For linear accelerators, modus operandi of control tests and their frequency are based on regulations and recommendations widely published, that are presented here. Concerning accessories, especially those recently developed (multi-leaf collimators, dynamic wedges,...), recommendations remains to be defined. Simple tests are proposed. Concerning numerical imaging systems, widely used for three dimensional dosimetry, image quality and geometry controls must be performed with fantom tests. For portal imaging, a quality assurance program is proposed. A strict and complete Quality Assurance program is essential to guarantee quality and safety of the treatment. A regular control of linear accelerator is one of the important component of this program. It suppose the implementation of permanent tests procedures, periodically modified following technological progresses and treatment techniques. Measurements must be sensible to variations below the tolerance level defined during the installation process. The analysis of the variations of measurements with time are an objective criterion of quality. (author)

    The international community presently lacks the ability to determine the quality and credibility of environmental measurements that is required to make sound decisions in matters related to international security, public health, and investment-related considerations. The ultimate goal of the work described in this article is to develop a credible information base including measurement capability for determination of environmental contamination and the potential for proliferation of material components of chemical or nuclear weapons. This study compared the accuracy obtained by six Russian and six U.S. laboratories for samples representative of classes of trace metals, dioxing-furans, and radioactive substances. The results obtained in this work indicate that current estimates for laboratory accuracy are likely overly optimistic. The weaknesses discovered by this prototype U.S. - Russia study also exist within the broader international community of laboratories. Further work is proposed to address the urgent need for the international community to improve performance evaluations for analytical measurements. (author)

    Graf, J.D.; Haeberlin, H.

    2000-01-01

    This project-overview published by the University of Applied Science in Burgdorf, Switzerland, looks back at the history of the university's testing laboratory for inverters for use in photovoltaic installations and discusses the work done there. After its move from Oberburg to Burgdorf in the early nineties, the laboratory was equipped to provide testing facilities for inverters up to 60 kW. Additions have been made to the infrastructure since then to facilitate the testing of various types of inverter produced in Switzerland and other countries. The measurements that can be carried out, including DC-AC conversion efficiency, harmonics, RF interference, islanding, sensitivity to tele-control signals, turn-on power and operating voltage range are described. The improvement in the quality of the inverters tested is discussed and the importance of continued testing as new manufacturers come onto the market is emphasised. The installation of further testing equipment, such as a 25 kW solar generator simulator and apparatus for the testing of maximum-power-tracking efficiency is discussed

  4. Organizing quality control programmes

    1989-01-01

    When procuring new equipment, performance and safety should be specified, if possible by reference to international standards. Some of the characteristics of the International Electrotechnical Commission (IEC) standard for X-ray generators, in particular the accuracy of the operating data, are described. The quality control tests to be performed after installation comprise acceptance test, status test and constancy test. The first two involve absolute measurements and will be the responsibility of physicists or engineers. Apparently limiting values stipulated by users are a factor of two lower than the limits of the IEC standard. By means of an example it is shown that modern X-ray generators can meet the lower limits of the users without problems. In order to obtain optimum initial quality when procuring new equipment operating data, limiting values must be specified and must be verified by acceptance testing, etc. However, in many countries physicists and engineers are not available for this job. A relatively uncomplicated test object can be used by radiographers for checks on fluoroscopic systems. The findings from such tests in Denmark are compared with other published findings and good agreement is found. Therefore it is proposed that such uncomplicated tests could form the basis for quality evaluation. (author)

    Suess, C.; Kalender, W.A.

    1998-01-01

    Since its introduction in 1989 spiral CT has gained wide clinical acceptance and meanwhile it covers a large range of CT applications. This new technology, however, has not yet been recognized and acknowledged in the national or international regulations on scanner quality assurance (QA) programs. The conventional QA procedures should be extended to check the distribution of resolution and noise within the image plane. Imaging performance in the axial direction constitutes one of the major advantages of spiral scanning. Therefore, the slice sensitivity profiles and the spatial and low-contrast resolution along the z-axis have to be assessed. The high demands on table feed accuracy require additional tests. We suggest phantoms and procedures to check and quantify these parameters. Thereby, we hope to support the ongoing discussion about spiral CT quality assurance. (orig.) [de

    A quality assurance program in radiation oncology monitors and evaluates any departmental functions which have an impact on patient outcome. The ultimate purpose of the program is to maximize health benefit to the patient without a corresponding increase in risk. The foundation of the program should be the credo: at least do no harm, usually do some good and ideally realize the greatest good. The steep dose response relationships for tumor control and complications require a high degree of accuracy and precision throughout the entire process of radiation therapy. It has been shown that failure to control local disease with radiation may result in decreased survival and may increase the cost of care by a factor of 3. Therefore, a comprehensive quality assurance program which seeks to optimize dose delivery and which encompasses both clinical and physics components, is needed

    Fanslau, Melody; Young, Janelle

    The production of a quality and safe food product is essential to the success of any food manufacturing facility. Because of this great importance, a career in quality can be extremely rewarding. Without happy customers willing to buy a product, a company would not be able to survive. Quality issues such as foreign objects, spoiled or mislabeled product, failure to meet net weight requirements, or a recall can all turn customers away from buying a product. The food industry is a customer-driven market in which some consumers are brand loyal based on a history of high quality or in which a single bad experience with a product will turn them away for a lifetime. With this said, the main role of a quality department is to help ensure that quality issues such as these are eliminated or kept to a minimum to maintain or increase the number of customers purchasing their product.

    K & S operates the largest and one of the most comprehensive Accredited Dosimetry Calibration Laboratories (ADCLs) in the American Association of Physicists in Medicine (AAPM) secondary laboratory system. It offers calibrations covering energies from Grenz-Ray (0.03-mm Al) to cesium-137 and cobalt-60, brachytherapy source and well chamber calibrations for low-activity sources, and, recently, high-dose-rate iridium-192. The present Quality Assurance (QA) program at K & S began with the AAPM Guidelines for Accreditation (Task Group No. 22 and No. 3, 1989) and grew over the past 10 years to include all aspects of providing a private, self-supporting calibration service from a free-standing independent facility. Some aspects of the QA program were prompted by the requirements of the nuclear power industry while other parts were from national consensus standards or the experiences of staff. Redundancy and teamwork are the most important characteristics of this QA program. K & S has participated in a National Institute of Standards and Technology (NIST) measurement quality assurance (MQA) program since 1982, and, in recent years, an ADCL intralaboratory intercomparison was conducted by Task Group 3 of the Radiation Therapy Committee of the AAPM. One measure of the credibility of a QA program is consistent performance on the MQA program and the ADCL intercomparisons over the past 10 years. An equally important measure of the ability of a program to assure quality results is the frequency of reported errors.

    The fact that Quality Assurance was imported from abroad and our reticence to reach agreement on single and accurate texts explain, if not excuse, the abundance of reference requirements existing on the French nuclear market with respect to Quality Assurance Programmes. But all is not lost, since the IAEA Good Practice Code is perhaps the solution that, in a few years time, will enable all French industrialists to work and be assessed by their customers, according to the same reference text [fr

    Etched track detectors are widely used for the detection of radon and its decay products. The reliability of radon measurement performed with such devices requires that laboratories producing analytical data are able to provide results of the required quality. The need for uniform results from laboratories at an international level therefore requires the implementation of a quality assurance programme, the harmonization of criteria, sampling procedures, calculations and the reporting of results, agreed on the basis of fundamental principles and international standards. The quality assurance programme described here is the first step on the way to ISO/IEC 17025 certification for the RI-RN (ISPESL) laboratory.

    Population-wide health equity monitoring remains isolated from mainstream healthcare quality assurance. As a result, healthcare organizations remain ill-informed about the health equity impacts of their decisions - despite becoming increasingly well-informed about quality of care for the average patient. We present a new and improved analytical approach to integrating health equity into mainstream healthcare quality assurance, illustrate how this approach has been applied in the English National Health Service, and discuss how it could be applied in other countries. We illustrate the approach using a key quality indicator that is widely used to assess how well healthcare is co-ordinated between primary, community and acute settings: emergency inpatient hospital admissions for ambulatory care sensitive chronic conditions ("potentially avoidable emergency admissions", for short). Whole-population data for 2015 on potentially avoidable emergency admissions in England were linked with neighborhood deprivation indices. Inequality within the populations served by 209 clinical commissioning groups (CCGs: care purchasing organizations with mean population 272,000) was compared against two benchmarks - national inequality and inequality within ten similar populations - using neighborhood-level models to simulate the gap in indirectly standardized admissions between most and least deprived neighborhoods. The modelled inequality gap for England was 927 potentially avoidable emergency admissions per 100,000 people, implying 263,894 excess hospitalizations associated with inequality. Against this national benchmark, 17% of CCGs had significantly worse-than-benchmark equity, and 23% significantly better. The corresponding figures were 11% and 12% respectively against the similar populations benchmark. Deprivation-related inequality in potentially avoidable emergency admissions varies substantially between English CCGs serving similar populations, beyond expected statistical

    2004-01-01

    This article reviews the present status of research work and development of various test objects, phantoms and detector/instrumentation systems for quality assurance (QA) of computed tomography (CT) scanners, carried out in advanced countries, with emphasis on similar work done in this research centre. CT scanner is a complex equipment and routine quality control procedures are essential to the maintenance of image quality with optimum patient dose. Image quality can be ensured only through correlation between prospective monitoring of system components and tests of overall performance with standard phantoms. CT examinations contribute a large share to the population dose in advanced countries. The unique dosimetry problems in CT necessitate special techniques. This article describes a comprehensive kit developed indigenously for the following QA and type approval tests as well as for research studies on image quality/dosimetry on CT scanners

    The considerations of tissue response to radiation absorbed dose suggest a need for an accuracy of +/-5% in its delivery. This is very demanding and its regular achievement requires careful quality control. There are three distinct phases to the delivery of the planned treatment: calibration of the radiation beam in a reference situation, calculation of the dose distribution for a patient relative to the reference dose and the delivery of the radiation to the patient as planned. Each has distinctly different quality assurance requirements and must be diligently observed if the desired accuracy is to be achieved

  6. Reliability, availability, and quality assurance considerations for fusion components

    International Nuclear Information System (INIS)

    Buende, R.

    1995-01-01

    The complexity of magnetic confinement machines has been a matter of concern in developing fusion power plants as electricity generating stations because it might reduce plant availability. A comprehensive reliability and availability (R and A) programme to determine the availability of a next step fusion machine was performed during definition and conceptual design of the Next European Torus. In addition to giving an overview of the expected contributions to unavailability of the various components, this activity identified the basic approach to be taken to specify and to achieve necessary improvements. This paper, after giving some basic definitions, describes the essentials of the R and A programme, its results, and the guidelines derived for further work towards a sufficiently reliable fusion plant. These guidelines refer to improvement of the reliability database and the quality assurance to be performed at the design stage of a next step machine. (orig.)

    1975-01-01

    The Quality Assurance (QA) policies and procedures described have been developed specifically for use in commercial nuclear projects. These policies and procedures are intended to provide assurance to Braun Management and the client that the plant will be safe, reliable, and operable, plus meet the requirements of the Nuclear Regulatory Commission, NRC. The Braun QA Manual provides QA procedures for (1) engineering and design, (2) procurement of materials, equipment, and services, and (3) construction and installation. The controls for safety-related systems established in the manual cover all phases of work from project inception to plant completion prior to operation by the owner. The manual standardizes Braun QA control procedures. These procedures are supplemented by Project QA Instructions prepared for each project. (U.S.)

  9. British standard (BS) 5750--quality assurance?

    Science.gov (United States)

    Pratt, D J

    1995-04-01

    BS5750 is the British Standard on "Quality Systems". Its equivalent in European Standards is EN29000 and in the International Standards Organisation ISO9000. This paper points out that these standards lay down formalised procedures and require documentation but do not ipso facto lead to quality assurance. The author points to the Japanese post-war industrial success as being an example of Total Quality Management within the framework provided by the philosophy of Dr. W. Edwards Deming (1988 and 1993). This philosophy on the management of "systems" to provide high quality products and services is briefly outlined. The author argues that improvement in prosthetic and orthotic services will not be reached through implementation of BS5750 but rather through radical rethinking and the adoption and application of the Deming philosophy.

    2017-10-01

    In 2006, the Federal Joint Committee introduced a quality assurance programme for ambulatory dialysis treatment in Germany. Regarding the impact of chronic dialysis treatment on the quality of life of patients and on health care costs, quality assurance in dialysis is considered highly relevant. The directive on Quality Assurance in Dialysis (QSD-RL) established an external quality assurance programme on the basis of the assessment of certain quality parameters combined with an internal quality management system based on benchmarking parameters in all dialysis practices and centres. Data on quality parameters are collected and analysed quarterly. Regional associations of statutory health insurance physicians take responsibility for quality improvement measures and sanctions. This article aims to provide an overview of the development of quality parameters from 2008 to 2015. We analysed the summarised annual quality reports published on the website of the Federal Joint Committee between 2009 and 2016. We present results on the so-called core quality parameters duration and frequency of dialysis sessions (both for haemodialysis patients), wKt/V for peritoneal dialysis patients, and percentage of haemodialysis patients with central venous catheters which has only been measured since 2014. In 2015, 92,000 patients received outpatient dialysis. Between 2008 and 2015, the results for the core quality parameters duration and frequency of haemodialysis improved while the results for wKt/V seemingly show an unfavourable trend. The percentage of patients with central venous catheters appears to be quite high, and thus indicates that there is potential for quality improvement. For the future, the Federal Joint Committee has resolved to merge the quality assurance programmes in dialysis and in kidney transplantation into a newly designed programme that has the potential to follow patients through all stages and kinds of renal replacement therapy and to focus on further aspects

    Until recently, the quality of U.S. radioassay laboratory services has been evaluated by a limited number of governmental measurement assurance programs (MAPs). The major programs have been limited to the U.S. Department of Energy (DOE), the U.S. Environmental Protection Agency (EPA) and the U.S. Nuclear Regulatory Commission (NRC). In 1988, an industry MAP was established for the nuclear power utility industry through the U.S. Council for Energy Awareness/National Institute of Standards and Technology (USCEA/NIST). This program functions as both a MAP for utility laboratories and/or their commercial contractor laboratories, and as a traceability program for the U.S. radioactive source manufacturers and the utility laboratories. Each of these generic MAPs has been initiated and is maintained to serve the specific needs of the sponsoring agency or organization. As a result, there is diversification in their approach, scope, requirements, and degree of traceability to NIST. In 1987, a writing committee was formed under the American National Standards Institute (ANSI) N42.2 committee to develop a standard to serve as the basis document for the creation of a national measurement quality assurance (MQA) program for radioassay laboratories in the U.S. The standard is entitled, open-quotes Measurement Quality Assurance For Radioassay Laboratories.open-quotes The document was developed to serve as a guide for MQA programs maintained for the specialized sectors of the radioassay community, such as bioassay, routine environmental monitoring, environmental restoration and waste management, radiopharmaceuticals, and nuclear facilities.

    Treatment success in hospitals, particularly in intensive care units, is directly tied to quality of structure, process, and outcomes. Technological and medical advancements lead to ever more complex treatment situations with highly specialized tasks in intensive care nursing. Quality criteria that can be used to describe and correctly measure those highly complex multiprofessional situations have only been recently developed and put into practice.In this article, it will be shown how quality in multiprofessional teams can be definded and assessed in daily clinical practice. Core aspects are the choice of a nursing theory, quality assurance measures, and quality management. One possible option of quality assurance is the use of standard operating procedures (SOPs). Quality can ultimately only be achieved if professional groups think beyond their boundaries, minimize errors, and establish and live out instructions and SOPs.

    This evaluation was conducted over an eight-month period from February 4 through October 1, 1980. During this time, field sampling was suspended for an indefinite time period while the National Uranium Resource Evaluation (NURE) Program underwent restructuring. In addition, the Uranium Resource Evaluation (URE) Project archives are being restructured. Since it is difficult to evaluate quality assurance needs of a program that is undergoing drastic change and because sections of the evaluation were well along before these changes were announced, this evaluation reflects the situation as it was during February 1980. The following quality assurance related programs are continuing to date: (1) periodic checks of field sampling procedures by the Supervising Field Geologist and the Director of Field Operations; (2) verification of field form information and laboratory analytical data verification for all geochemical surveys; (3) URE Project laboratory quality control program (all elements routinely analyzed); and (4) Ames interlaboratory quality control program (uranium only). UCC-ND was given the responsibility of conducting a Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) survey in the Central United States (Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Nebraska, North Dakota, Oklahoma, Texas, South Dakota, and Wisconsin). During 1979 and 1980, 13 detailed surveys were conducted by the URE Project in the Central and Western United States to characterize the hydrogeochemistry, stream sediment geochemistry, and/or radiometric patterns of known or potential uranium occurrences. Beginning in 1980, the HSSR surveys were modified to the Regional Hydrogeochemical and Stream Sediment (RHSS) surveys

    Accuracy and repeatability of spirometry measurements are essential to obtain reliable efficacy data in randomized asthma clinical trials. We report our experience with a centralized spirometry quality assurance program that we implemented in our phase III asthma trials. Six asthma trials of 4 to 21 weeks in duration were conducted at 232 clinical centers in 31 countries. Approximately 23,100 prebronchodilator and 13,700 postbronchodilator spirometry tests were collected from 2523 adult and 336 pediatric asthmatic patients. The program used a standard spirometer (the Renaissance spirometry system) with maneuver quality messages and automated quality grading of the spirometry tests. Each clinical center transmitted spirometry data weekly to a central database, where uniform monitoring of data quality was performed and feedback was provided in weekly quality reports. Seventy-nine percent of all patients performed spirometry sessions with quality that either met or exceeded American Thoracic Society standards and improved over time. Good-quality spirometry was associated with (1) less severe asthma; (2) active treatment; (3) infrequent nocturnal awakenings; (4) age above 15 years; and (5) low body weight. Maneuver-induced bronchospasm was rare. Good-quality spirometry was observed in multicenter asthma clinical trials that employed a standard spirometer and continuous monitoring. Both within- and between-patient variability decreased. Spirometry quality improved with time as study participants and technicians gained experience.

    New regulations for nuclear power plants emphasize more quality assurance than it was the case in the past. Quality assurance is a management tool. During erection the quality assurance measures of the manufacturer, the main contractor and the required quality and the reliability of the proof of quality. The qualification of processes, equipment and personnel is a significant measure of quality assurance. The proof for quality assurance to be effective needs not only system-oriented audits, but also product audits aimed at quality characteristics of the product itself. The existing problems of examination techniques not optimized according to latest experience and of the large volume of documetation will persist in case the existing regulations are not adjusted according to the results of relevant studies. Furthermore the effectiveness of quality assurance is too often hampered by vague definitions of the safety objectives. (orig.) [de

    On basis of guidelines for development of QUALITY SYSTEM for a testing laboratory (European Standard Series EN 45000) a quality assurance system was implemented in gamma spectroscopy laboratory, where routine measurements of natural (mainly Ra-226, Ra-228, Ra-224, K-40) and artificial (mainly Cs-137 and Cs-134) isotopes are performed. We measure a variety of samples, but mainly coal, vaste rock, ashe, deposits, vegetation and air filters. Laboratory of gamma spectroscopy in Central Mining Institute has three HPGe detectors. There is one coaxial detector with 45% relative efficiency, one detector for low energy region and one detector with extended range). We have also two Ge(Li) detectors from former Czechoslovakia. Shielding is made mainly of steel (40 cm) with the interior covered with lead and copper. The electronics and software (Genie-PC) was bought at 'Canberra' and 'Silena'. The paper describes not only the system of quality assurance but also main problems met by its implementation and results of intercomparison measurements. The QAS has been introduced in 1992. In 1993 the Accreditation Certificate of Testing Laboratory for our Laboratory has been obtained from the Polish Bureau of Research and Certification as a fifth laboratory in Poland. (author)
