The European co-operation for Accreditation (EA) formalises the collaboration of the Accreditation Bodies of the Member States of the European Union and the European Free Trade Association covering all conformity assessment activities. This collaboration is based on a Memorandum of Understanding dated the 27 November 1997 and aims at developing and maintain Multilateral Agreements (MLAs) within EA and with non-members accreditation bodies. MLAs Signatories guarantee uniformity of accreditation by continuous and rigorous evaluation. Based on mutual confidence, the MLAs recognise the equivalence of the accreditation systems administered by EA Members and of certificates and reports issued by bodies accredited under these systems. A basic element of the program to establish and maintain mutual confidence among calibration services is the participation of the accredited laboratories in experimental interlaboratory comparisons (ILC) organised by EA members or other international organisations. The aim of these ILC is to verify the technical equivalence of calibration services within the EA. The ILC which it is dealt with in the present work was recently carried out over a period of two years, ending in May 2002. It interested the laboratories accredited in the ionising radiation field for calibration of dosimeters at radiation protection levels in terms of the quantity air kerma (K air ) due to 6 0C o and 1 37C s gamma radiation. The ILC was planned by the EA expert group on Ionising radiation and radioactivity and approved by the EA General Assembly in December 1999 with the title Calibration of a Radiation Protection Dosimeter under the code IR3. The need of this comparison also resulted from an inquiry carried out in 1998 by the expert group among the different Accreditation Bodies members of EA and associated to EA. The organization of the ILC was carried out according to the EA rules by the Italian Accreditation Body in the ionising radiation field, the SIT

The objective of this study was to analyze the current situation of laboratory accreditation (LA) in Thailand, especially on occupational and environmental health. The study integrated both quantitative and qualitative approaches. The response rate of the quantitative questionnaires was 54.5% (226/415). The majority of the responders was environmental laboratories located outside hospital and did not have proficiency testing. The majority used ISO 9000, ISO/IEC 17025 or ISO/ EEC Guide 25, and hospital accreditation (HA) as their quality system. However, only 30 laboratories were currently accredited by one of these systems. Qualitative research revealed that international standard for laboratory accreditation for both testing laboratory and calibration laboratory was ISO/IEC Guide 25, which has been currently revised to be ISO/IEC 17025. The National Accreditation Council (NAC) has authorized 2 organizations as Accreditation Bodies (ABs) for LA: Thai Industrial Standards Institute, Ministry of Industry, and Bureau of Laboratory Quality Standards, Department of Medical Sciences, Ministry of Public Health. Regarding LA in HA, HA considered clinical laboratory as only 1 of 31 items for accreditation. Obtaining HA might satisfy the hospital director and his management team, and hence might actually be one of the obstacles for the hospital to further improve their laboratory quality system and apply for ISO/IEC 17025 which was more technically oriented. On the other hand, HA may be viewed as a good start or even a pre-requisite for laboratories in the hospitals to further improve their quality towards ISO/IEC 17025. Interviewing the director of NAC and some key men in some large laboratories revealed several major problems of Thailand's LA. Both Thai Industrial Standards Institute and Bureau of Laboratory Quality Standards did not yet obtain Mutual Recognition Agreement (MRA) with other international ABs. Several governmental bodies had their own standards and

Practice for characterization and performance of a high-dose radiation dosimetry calibration laboratory

International Nuclear Information System (INIS)

2003-01-01

This practice addresses the specific requirements for laboratories engaged in dosimetry calibrations involving ionizing radiation, namely, gamma-radiation, electron beams or X-radiation (bremsstrahlung) beams. It specifically describes the requirements for the characterization and performance criteria to be met by a high-dose radiation dosimetry calibration laboratory. The absorbed-dose range is typically between 10 and 10 5 Gy. This practice addresses criteria for laboratories seeking accreditation for performing high-dose dosimetry calibrations, and is a supplement to the general requirements described in ISO/IEC 17025. By meeting these criteria and those in ISO/IEC 17025, the laboratory may be accredited by a recognized accreditation organization. Adherence to these criteria will help to ensure high standards of performance and instill confidence regarding the competency of the accredited laboratory with respect to the services it offers

In Hungary, the National Accreditation Body was established by government in 1995 as an independent, non-profit organization, and has exclusive rights to accredit, amongst others, medical laboratories. The National Accreditation Body has two Specialist Advisory Committees in the health care sector. One is the Health Care Specialist Advisory Committee that accredits certifying bodies, which deal with certification of hospitals. The other Specialist Advisory Committee for Medical Laboratories is directly involved in accrediting medical laboratory services of health care institutions. The Specialist Advisory Committee for Medical Laboratories is a multidisciplinary peer review group of experts from all disciplines of in vitro diagnostics, i.e. laboratory medicine, microbiology, histopathology and blood banking. At present, the only published International Standard applicable to laboratories is ISO/IEC 17025:1999. Work has been in progress on the official approval of the new ISO 15189 standard, specific to medical laboratories. Until the official approval of the International Standard ISO 15189, as accreditation standard, the Hungarian National Accreditation Body has decided to progress with accreditation by formulating explanatory notes to the ISO/IEC 17025:1999 document, using ISO/FDIS 15189:2000, the European EC4 criteria and CPA (UK) Ltd accreditation standards as guidelines. This harmonized guideline provides 'explanations' that facilitate the application of ISO/IEC 17025:1999 to medical laboratories, and can be used as a checklist for the verification of compliance during the onsite assessment of the laboratory. The harmonized guideline adapted the process model of ISO 9001:2000 to rearrange the main clauses of ISO/IEC 17025:1999. This rearrangement does not only make the guideline compliant with ISO 9001:2000 but also improves understanding for those working in medical laboratories, and facilitates the training and education of laboratory staff.

Accreditation or certification is a recognition given to an operation or product that has been evaluated against a standard; be it regulatory or voluntary. The purpose of accreditation is to provide the consumer with a level of confidence in the quality of operation (process) and the product of an organization. Environmental Protection Agency/OCM has proposed the development of an accreditation program under National Environmental Laboratory Accreditation Program for Good Laboratory Practice (GLP) laboratories as a supplement to the current program. This proposal was the result of the Inspector General Office reports that identified weaknesses in the current operation. Several accreditation programs can be evaluated and common components identified when proposing a structure for accrediting a GLP system. An understanding of these components is useful in building that structure. Internationally accepted accreditation programs provide a template for building a U.S. GLP accreditation program. This presentation will discuss the traditional structure of accreditation as presented in the Organization of Economic Cooperative Development/GLP program, ISO-9000 Accreditation and ISO/IEC Guide 25 Standard, and the Canadian Association for Environmental Analytical Laboratories, which has a biological component. Most accreditation programs are managed by a recognized third party, either privately or with government oversight. Common components often include a formal review of required credentials to evaluate organizational structure, a site visit to evaluate the facility, and a performance evaluation to assess technical competence. Laboratory performance is measured against written standards and scored. A formal report is then sent to the laboratory indicating accreditation status. Usually, there is a scheduled reevaluation built into the program. Fee structures vary considerably and will need to be examined closely when building a GLP program.

For calibration laboratories, routine calibrations of instruments meeting stated accuracy goals are important. One method of achieving the accuracy goals is to establish and follow a quality assurance program designed to monitor all aspects of the calibration program and to provide the appropriate feedback mechanism if adjustments are needed. In the United States there are a number of organizations with laboratory accreditation programs. All existing accreditation programs require that the laboratory implement a quality assurance program with essentially the same elements in all of these programs. Collectively, these elements have been designated as a Measurement Quality Assurance (MQA) program. This paper will briefly discuss the interrelationship of the elements of an MQA program. Using the Center for Devices and Radiological Health (CDRH) X-ray Calibration Laboratory (XCL) as an example, it will focus on setting up a quality control program for the equipment in a Secondary Calibration Laboratory.

Currently, there is a great deal of discussion among industry and government agencies about ISO 9000 accreditation. U.S. manufacturers with ISO 9000 accreditation are regarded more favorably by European countries. The principles behind the ISO 9000 accreditation are based on the Total Quality Management (TQM) principles that are being implemented in many U.S. industries. This paper will deal only with the calibration issue. There is a difference in the areas covered by ISO 9000 and ISO Guide 25 documents. ISO 9000, in particular ISO 9001 - ISO 9003, cover the open-quotes calibrationclose quotes of inspection, measuring and test equipment. This equipment is basically used for open-quotes factory calibrationsclose quotes to determine that equipment is performing within manufacturer specifications. ISO Guide 25 is specifically for open-quotes calibration and testing laboratories,close quotes generally laboratories that have painstaking procedures to reduce uncertainties and establish high accuracy of the transfer of calibration. The experience of the University of Wisconsin Accredited Dosimetry Calibration Laboratory in conforming to ISO Guide 25 will be outlined. The entire laboratory staff must become familiar with the process and an individual with direct authority must become the one to maintain the quality of equipment and calibrations in the role of open-quotes quality-assurance manager.close quotes

Full text: Accreditation of laboratories has been practiced for well over one hundred years with the primary objective of seeking a formal recognition for the competence of a laboratory to perform specified tests or measurements. While first accreditation schemes intended initially to serve only the immediate needs of the body making the evaluation with the purpose of minimizing testing and inspection to be conducted by laboratories, third-party accreditation enables a laboratory to demonstrate its capability as well as availability of all necessary resources to undertake particular tests correctly and that is managed in such a way that it is likely to do this consistently, taking into consideration standards developed by national and international standards-setting bodies. The international standard ISO/IEC 17025 and laboratory accreditation are concerned with competence and quality management of laboratories only, thus requiring a single common set of criteria applicable to them. Quality assurance is therefore fully relevant to laboratories in general and analytical laboratories in particular; it should not be confused with the certification approach according to ISO/IEC 9000 family of standards, that is concerned with quality management applicable to any organization as a whole. The role of laboratory accreditation can be manifold, but in all cases the recipient of the test report needs to have confidence that the data in it is reliable, particularly if the test data is important in a decision-making process. As such, it offers a comprehensive way to ensure: - the availability of managerial and technical staff with the authority and resources needed; - the effectiveness of equipment management, traceability of measurement and safety procedures; - the performance of tests, taking into consideration laboratory accommodation and facilities as well as laboratory practices. The presentation will include also some practical aspects of quality management system

Accreditation - Its relevance for laboratories measuring radionuclides

Accreditation is an internationally recognised way for laboratories to demonstrate their competence. Obtaining and maintaining accreditation is, however, a costly and time-consuming procedure. The benefits of accreditation also depend on the role of the laboratory. Accreditation may be of limited relevance for a research laboratory, but essential for a laboratory associated with a national authority and e.g. issuing certificates. This report describes work done within the NKSBOK-1.1 sub-project on introducing accreditation to Nordic laboratories measuring radionuclides. Initially the focus was on the new standard ISO/IEC 17025, which was just in a draft form at the time, but which provides now a new framework for accreditation of laboratories. Later the focus was widened to include a general introduction to accreditation and providing through seminars a forum for exchanging views on the experience laboratories have had in this field. Copies of overheads from the last such seminar are included in the appendix to this report. (au)

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

Ramos, Manoel Mattos Oliveira

2009-01-01

The demand for calibration services and quality control in diagnostic radiology has grown in the country since the publication of the governmental regulation 453, issued by the Ministry of Health in 1998. At that time, to produce results facing the new legislation, many laboratories used different standards and radiation qualities, some of which could be inadequate. The international standards neither supplied consistent radiation qualities and standardization for the different types of equipment available. This situation changed with the publication of the new edition of the IEC 61267 standard, published in 2005. A metrology network was created, but it is not yet accredited by the accreditation organism of the country, INMETRO. The objective of this work was to implement the standardization of the air kerma for the un attenuated qualities (RQR) of IEC 61267, and to develop a requirement proposal for instruments calibration laboratories. Results of interlaboratory comparisons demonstrate that the quantity is standardized and internationally traceable. A laboratory requirement proposal was finalized and it shall be submitted to INMETRO to be used as auxiliary normative document in laboratory accreditation. (author)

Clinical toxicology laboratories and forensic toxicology laboratories operate in a highly regulated environment. This article outlines major US legal/regulatory issues and requirements relevant to accreditation of toxicology laboratories (state and local regulations are not covered in any depth). The most fundamental regulatory distinction involves the purposes for which the laboratory operates: clinical versus nonclinical. The applicable regulations and the requirements and options for operations depend most basically on this consideration, with clinical toxicology laboratories being directly subject to federal law including mandated options for accreditation and forensic toxicology laboratories being subject to degrees of voluntary or state government–required accreditation.

This International Standard, based upon ISO/IEC 17025 and ISO 9001, provides requirements for competence and quality that are particular to medical laboratories. While this International Standard is intended for use throughout the currently recognized disciplines of medical laboratory services, those working in other services and disciplines will also find it useful and appropriate. In addition, bodies engaged in the recognition of the competence of medical laboratories will be able to use this International Standard as the basis for their activities. The Japan Accreditation Board for Conformity Assessment (AB) and the Japanese Committee for Clinical Laboratory Standards (CCLS) are jointly developing the program of accreditation of medical laboratories. ISO 15189 requirements consist of two parts, one is management requirements and the other is technical requirements. The former includes the requirements of all parts of ISO 9001, moreover it includes the requirement of conformity assessment body, for example, impartiality and independence from any other party. The latter includes the requirements of laboratory competence (e.g. personnel, facility, instrument, and examination methods), moreover it requires that laboratories shall participate proficiency testing(s) and laboratories' examination results shall have traceability of measurements and implement uncertainty of measurement. Implementation of ISO 15189 will result in a significant improvement in medical laboratories management system and their technical competence. The accreditation of medical laboratory will improve medical laboratory service and be useful for patients.

Within the regional markets, as it is the case of MERCOSUR , the laboratories which are suppliers of test and calibration results, are mutually recognized through the National Accreditation Systems. In Argentina there is a project to create a Center for the Accreditation of Test Laboratories. CNEA, which is involved in the execution of large projects and has adopted quality assurance criteria for a long time, requires for internal and external laboratories to be qualified. At the beginning of this year, a Committee for the Qualification of Laboratories was created in the Research and Development and Fuel Cycle Areas. Its objective was planning, management of documents, coordination, evaluation and quantification of laboratories, according to national IRAM and international ISO standards. This paper analyzes the organization of the system and the methods to evaluate and qualify laboratories as a process of growing up leading to the future National Accreditation System.

According to the framework decision of the European Union Council, genetic laboratories which perform tests for the benefit of the law enforcement agencies and the administration of justice are required to obtain a certificate of accreditation testifying to compliance with the PN EN ISO/IEC 17025:2005 standard. The certificate is the official confirmation of the competence to perform research, an acknowledgement of credibility, impartiality and professional independence. It is also the proof of establishment, implementation and maintenance of an appropriate management system. The article presents the legal basis for accreditation, the procedure of obtaining the certificate of accreditation and selected elements of the management system.

Schneebeli, Jorge E.; Zampini, Juan J.; Naucevich, Alfredo

2000-01-01

The ISO 25 Guide (IRAM 301) replaced by ISO 17025 is the standard applied for the implementation of a quality system in a test or calibration laboratory. This document is not known as ISO 9000, but it is the proper standard for this kind of laboratory. This document establishes requirements no just for the quality system in general, but on technical competence, that means the laboratory technical aptitude to carry out the tests. The aim of this paper is to comment the criteria used in the Radiographic Laboratory of CEMEC, that have been assessed by the United King dome Accreditation Service (UKAS). (author)

Internationally-accredited laboratories are recognised for their superior test reliability, operational performance, quality management and competence. In a bid to meet international quality standards, the Mozambique National Institute of Health enrolled the National Tuberculosis Reference Laboratory (NTRL) in a continuous quality improvement process towards ISO 15189 accreditation. Here, we describe the road map taken by the NTRL to achieve international accreditation. The NTRL adopted the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme as a strategy to implement a quality management system. After SLMTA, the Mozambique National Institute of Health committed to accelerate the NTRL's process toward accreditation. An action plan was designed to streamline the process. Quality indicators were defined to benchmark progress. Staff were trained to improve performance. Mentorship from an experienced assessor was provided. Fulfilment of accreditation standards was assessed by the Portuguese Accreditation Board. Of the eight laboratories participating in SLMTA, the NTRL was the best-performing laboratory, achieving a 53.6% improvement over the SLMTA baseline conducted in February 2011 to the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) assessment in June 2013. During the accreditation assessment in September 2014, 25 minor nonconformities were identified and addressed. In March 2015, the NTRL received Portuguese Accreditation Board recognition of technical competency for fluorescence smear microscopy, and solid and liquid culture. The NTRL is the first laboratory in Mozambique to achieve ISO 15189 accreditation. From our experience, accreditation was made possible by institutional commitment, strong laboratory leadership, staff motivation, adequate infrastructure and a comprehensive action plan.

The DOE Laboratory Accreditation Program was implemented in 1986. Currently, the program is conducting its seventeenth performance testing session for whole body personnel dosimeters. All but two DOE laboratories have gained accreditation for their whole body personnel dosimetry systems. Several test situations which were anticipated in the early stages of DOELAP have not materialized. In addition, the testing standard for whole body personnel dosimetry systems is under review and revision. In the near future, the accreditation programs for extremity dosimetry and bioassay will be implemented. This presentation summarizes the status and anticipated direction of the DOE whole body and extremity dosimetry and bioassay laboratory accreditation program

Accreditation is emerging as a preferred framework for building quality medical laboratory systems in resource-limited settings. Despite the low numbers of laboratories accredited to date, accreditation has the potential to improve the quality of health care for patients through the reduction of testing errors and attendant decreases in inappropriate treatment. Accredited laboratories can become more accountable and less dependent on external support. Efforts made to achieve accreditation may also lead to improvements in the management of laboratory networks by focusing attention on areas of greatest need and accelerating improvement in areas such as supply chain, training, and instrument maintenance. Laboratory accreditation may also have a positive influence on performance in other areas of health care systems by allowing laboratories to demonstrate high standards of service delivery. Accreditation may, thus, provide an effective mechanism for health system improvement yielding long-term benefits in the quality, cost-effectiveness, and sustainability of public health programs. Further studies are needed to strengthen the evidence on the benefits of accreditation and to justify the resources needed to implement accreditation programs aimed at improving the performance of laboratory systems.

Malkoc, Ekrem; Neuteboom, Wim

2007-04-11

Forensic science is gaining some solid ground in the area of effective crime prevention, especially in the areas where more sophisticated use of available technology is prevalent. All it takes is high-level cooperation among nations that can help them deal with criminality that adopts a cross-border nature more and more. It is apparent that cooperation will not be enough on its own and this development will require a network of qualified forensic laboratories spread over Europe. It is argued in this paper that forensic science laboratories play an important role in the fight against crime. Another, complimentary argument is that forensic science laboratories need to be better involved in the fight against crime. For this to be achieved, a good level of cooperation should be established and maintained. It is also noted that harmonization is required for such cooperation and seeking accreditation according to an internationally acceptable standard, such as ISO/IEC 17025, will eventually bring harmonization as an end result. Because, ISO/IEC 17025 as an international standard, has been a tool that helps forensic science laboratories in the current trend towards accreditation that can be observed not only in Europe, but also in the rest of the world of forensic science. In the introduction part, ISO/IEC 17025 states that "the acceptance of testing and calibration results between countries should be facilitated if laboratories comply with this international standard and if they obtain accreditation from bodies which have entered into mutual recognition agreements with equivalent bodies in other countries using this international standard." Furthermore, it is emphasized that the use of this international standard will assist in the harmonization of standards and procedures. The background of forensic science cooperation in Europe will be explained by using an existing European forensic science network, i.e. ENFSI, in order to understand the current status of forensic

Medical laboratories are the key partners in patient safety. Laboratory results influence 70% of medical diagnoses. Quality of laboratory service is the major factor which directly affects the quality of health care. The clinical laboratory as a whole has to provide the best patient care promoting excellence. International Standard ISO 15189, based upon ISO 17025 and ISO 9001 standards, provides requirements for competence and quality of medical laboratories. Accredited medical laboratories enhance credibility and competency of their testing services. Our group of laboratories, one of the leading institutions in the area, had previous experience with ISO 9001 and ISO 17025 Accreditation at non-medical sections. We started to prepared for ISO 15189 Accreditation at the beginning of 2006 and were certified in March, 2007. We spent more than a year to prepare for accreditation. Accreditation scopes of our laboratory were as follows: clinical chemistry, hematology, immunology, allergology, microbiology, parasitology, molecular biology of infection serology and transfusion medicine. The total number of accredited tests is 531. We participate in five different PT programs. Inter Laboratory Comparison (ILC) protocols are performed with reputable laboratories. 82 different PT Program modules, 277 cycles per year for 451 tests and 72 ILC program organizations for remaining tests have been performed. Our laboratory also organizes a PT program for flow cytometry. 22 laboratories participate in this program, 2 cycles per year.

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

This section is well supported with practical illustrations and necessary tables and exhaustive details like preparation of a standard operating procedure and a quality manual. Concept of training and privileging of staff has been clarified and a few of the QC exercises have been dealt with in a novel way. Finally, a practical advice for facing an actual third party assessment and caution needed to prevent post-assessment pitfalls has been dealt with.

SPRT Calibration Uncertainties and Internal Quality Control at a Commercial SPRT Calibration Facility

Wiandt, T. J.

2008-06-01

The Hart Scientific Division of the Fluke Corporation operates two accredited standard platinum resistance thermometer (SPRT) calibration facilities, one at the Hart Scientific factory in Utah, USA, and the other at a service facility in Norwich, UK. The US facility is accredited through National Voluntary Laboratory Accreditation Program (NVLAP), and the UK facility is accredited through UKAS. Both provide SPRT calibrations using similar equipment and procedures, and at similar levels of uncertainty. These uncertainties are among the lowest available commercially. To achieve and maintain low uncertainties, it is required that the calibration procedures be thorough and optimized. However, to minimize customer downtime, it is also important that the instruments be calibrated in a timely manner and returned to the customer. Consequently, subjecting the instrument to repeated calibrations or extensive repeated measurements is not a viable approach. Additionally, these laboratories provide SPRT calibration services involving a wide variety of SPRT designs. These designs behave differently, yet predictably, when subjected to calibration measurements. To this end, an evaluation strategy involving both statistical process control and internal consistency measures is utilized to provide confidence in both the instrument calibration and the calibration process. This article describes the calibration facilities, procedure, uncertainty analysis, and internal quality assurance measures employed in the calibration of SPRTs. Data will be reviewed and generalities will be presented. Finally, challenges and considerations for future improvements will be discussed.

Full Text Available One and key of the priorities in laboratory medicine is improvement of quality management system for patient safety. Quality in the health care is tightly connected to the level of excellence of the health care provided in relation to the current level of knowledge and technical development. Accreditation is an effective way to demonstrate competence of the laboratory, a tool to recognize laboratories world-wide, is linked to periodical audits, to stimulate the maintenance and improvement of the quality, which leads to high standard of services for clients (patients, health care providers, etc.. The strategic plans of IFCC and EFLM include focusing on accreditation of labs based on ISO standards and cooperation with European Accreditation and national accreditation bodies. IFCC and EFLM recognised that ISO 15189:2012 Medical laboratories – Requirements for quality and competence, encompasses all the assessment criteria specified in the policy of quality. The last version is oriented to process approach with detailed division and clearly defined requirements. The accreditation of labs improves facilitation of accurate and rapid diagnostics, efficiency of treatment and reduction of errors in the laboratory process. Accreditation is not about who the best is, but who has a system of standard procedures with aim to improve the quality and patient safety. Quality system is about people, with people and for people.

The recognition of the technical capability of a testing laboratory is carried out by Laboratory Accreditation Bodies as the result of a satisfactory evaluation and the systematic follow up of the certified qualification. In Argentina the creation of a National Center for the Accreditation of Testing Laboratories, as a first step to assess a National Accreditation System is currently projected. CNEA, as an institution involved in technological projects and in the development and production of goods and services, has adopted since a long time ago quality assurance criteria. One of their requirements is the qualification of laboratories. Due to the lack of a national system, a Committee for the Qualification of Laboratories was created jointly by the Research and Development and Nuclear Fuel Cycle Areas with the responsibility of planning and management of the system evaluation and the certification of the quality of laboratories. The experience in the above mentioned topics is described in this paper. (author)

FLEXIBLE SCOPE IN ACCREDITATION - INTRODUCING VAGUENESS OR BETTER EXPRESSION OF SCOPE

Directory of Open Access Journals (Sweden)

Miloš Jelić

2007-09-01

Full Text Available Historically, laboratory accreditation has been grounded on fixed scope of accreditation to establish precisely and unambiguously the range of tests and calibrations covered by a granted accreditation. By the time elapsed it was noticed that such approach sometimes appears to be restrictive since it constrains new or modified methods to be added to a laboratory's scope, even where competence in this general area has already been demonstrated. Accreditation of a flexible scope places more of the responsibility onto the laboratory itself because it imposes to the laboratory to establish and maintain management system that can control its proposed approach. Flexible scope of accreditation yields benefit to all accreditation stakeholders but, on the other hand, introduces more requiring interpretations of relevant standard clauses and includes the bounds of the scope which are defined in more distinct way.

The quality management systems compliant with the ISO 9001:2009 have been thoroughly researched and described in detail in the world literature. The accredited management systems used in the testing laboratories and compliant with the ISO/IEC 17025:2005 have been mainly described in terms of the system design and implementation. They have also been investigated from the analytical point of view. Unfortunately, a low number of studies concerned the management system functioning in the accredited testing laboratories. The aim of following study was to assess the management system functioning in the accredited testing laboratories in Poland. On 8 October 2015, 1,213 accredited testing laboratories were present in Poland. They investigated various scientific areas and substances/objects. There are more and more such laboratories that have various problems and different long-term experience when it comes to the implementation, maintenance and improvement of the management systems. The article describes the results of the conducted expert assessment (survey) carried out to examine the conditions for the functioning of a management system in an accredited laboratory. It also focuses on the characteristics of the accredited research laboratories in Poland. The authors discuss the selection of the external and internal conditions that may affect the accredited management system. They show how the experts assessing the selected conditions were chosen. The survey results are also presented.

We describe our process for quality improvement (QI) for a 3-year accreditation cycle in echocardiography by the Intersocietal Accreditation Commission (IAC) for a large group practice. Echocardiographic laboratory accreditation by the IAC was introduced in 1996, which is not required but could impact reimbursement. To ensure high-quality patient care and community recognition as a facility committed to providing high-quality echocardiographic services, we applied for IAC accreditation in 2010. Currently, there is little published data regarding the IAC process to meet echocardiography standards. We describe our approach for developing a multicampus QI process for echocardiographic laboratory accreditation during the 3-year cycle of accreditation by the IAC. We developed a quarterly review assessing (1) the variability of the interpretations, (2) the quality of the examinations, (3) a correlation of echocardiographic studies with other imaging modalities, (4) the timely completion of reports, (5) procedure volume, (6) maintenance of Continuing Medical Education credits by faculty, and (7) meeting Appropriate Use Criteria. We developed and implemented a multicampus process for QI during the 3-year accreditation cycle by the IAC for Echocardiography. We documented both the process and the achievement of those metrics by the Echocardiography Laboratories at the Ochsner Medical Institutions. We found the QI process using IAC standards to be a continuous educational experience for our Echocardiography Laboratory physicians and staff. We offer our process as an example and guide for other echocardiography laboratories who wish to apply for such accreditation or reaccreditation. © 2016, Wiley Periodicals, Inc.

The public institution aims to promote excellence in public management to contribute to the quality of services provided to its customers and to increase competitiveness in the country, as well as its international projection. A technical barrier to trade that can lead to dissatisfaction and achieve the reputation of the institution is failing the test or calibration results and measurement data, thereby accreditation is regarded as the first essential step to facilitate the mutual acceptance of test results and calibration or measurement data. For recognition, laboratories need to demonstrate full compliance with both the sections of ISO/IEC 17025:2005, i.e. management and technical requirements. This research aims to discuss the critical aspects for implementation of ABNT NBR ISO / IEC 17025:2005 for calibration and testing of a Public Institution seeking accreditation of its laboratories with INMETRO, national accreditation body Laboratories. Besides getting preventive, corrective and improvement actions continues guidelines. Furthermore, the methodology used was to conduct a literature search and apply a questionnaire to identify the degree of agreement / disagreement of the foundations of the standard servers. Analysis of the results showed that the critical issues were: commitment, training, resources (infrastructure, human) and culture. (author)

CRCPD`S laboratory accrediation program

Energy Technology Data Exchange (ETDEWEB)

Dukes, P.M. [South Carolina Department of Health and Environmental Control, Columbia, SC (United States)

1993-12-31

The Conference of Radiation Control Program Directors, or CRCPD, first became involved in a calibration laboratory accreditation program about 17 years ago. Since that time, the CRCPD has formed a Committee on Ionizing Measurements which writes criteria for the accreditation of laboratories, and performs the accreditation review process. To become accredited, a laboratory must agree to an administrative review, and an onsite review, and participate in measurement quality assurance (MQA) testing with the National Institute of Standards and Technology (NIST). The CRCPD currently has four accredited laboratories. All the laboratories are working with the Conference in promoting the improvement of MQA in radiation control programs.

2017-03-01

Full Text Available Background: Quality-assured tuberculosis laboratory services are critical to achieve global and national goals for tuberculosis prevention and care. Implementation of a quality management system (QMS in laboratories leads to improved quality of diagnostic tests and better patient care. The Strengthening Laboratory Management Toward Accreditation (SLMTA programme has led to measurable improvements in the QMS of clinical laboratories. However, progress in tuberculosis laboratories has been slower, which may be attributed to the need for a structured tuberculosis-specific approach to implementing QMS. We describe the development and early implementation of the Strengthening Tuberculosis Laboratory Management Toward Accreditation (TB SLMTA programme. Development: The TB SLMTA curriculum was developed by customizing the SLMTA curriculum to include specific tools, job aids and supplementary materials specific to the tuberculosis laboratory. The TB SLMTA Harmonized Checklist was developed from the World Health Organisation Regional Office for Africa Stepwise Laboratory Quality Improvement Process Towards Accreditation checklist, and incorporated tuberculosis-specific requirements from the Global Laboratory Initiative Stepwise Process Towards Tuberculosis Laboratory Accreditation online tool. Implementation: Four regional training-of-trainers workshops have been conducted since 2013. The TB SLMTA programme has been rolled out in 37 tuberculosis laboratories in 10 countries using the Workshop approach in 32 laboratories in five countries and the Facility based approach in five tuberculosis laboratories in five countries. Conclusion: Lessons learnt from early implementation of TB SLMTA suggest that a structured training and mentoring programme can build a foundation towards further quality improvement in tuberculosis laboratories. Structured mentoring, and institutionalisation of QMS into country programmes, is needed to support tuberculosis laboratories

International Nuclear Information System (INIS)

Bhatt, B.C.; Srivastava, J.K.; Iyer, P.S.; Venkatraman, G.

1993-01-01

Accreditation for thermoluminescent dosimeters is the process of evaluating a programme intending to use TL personnel dosimeters to measure, report and record dose equivalents received by radiation workers. In order to test the technical competence for conducting personnel dosimetry service as well as to decentralize personnel monitoring service, it has been proposed by Radiological Physics Division (RPhD) to accredit some of the laboratories, in the country. The objectives of this accreditation programme are: (i) to give recognition to competent dosimetry processors, and (ii) to provide periodic evaluation of dosimetry processors, including review of internal quality assurance programme to improve the quality of personnel dosimetry processing. The scientific support for the accreditation programme will be provided by the scientific staff from Radiological Physics Division (RPhD) and Radiation Protection Services Division (RPSD). This paper describes operational and technical requirements for the Personnel Radiation Dosimetry Laboratory Accreditation Programme for Thermoluminescent Dosimeters for Personnel Dosimetry Processors. Besides, many technical documents dealing with the TL Personnel Dosimeter System have been prepared. (author). 5 refs., 2 figs

In the energetics of Republic of Macedonia, after 13 years of independence of the country, there is still chaos in applying of many standards that are not used any more, even in the countries from which they are taken over. Step forward is the applying of the new standards in the oil industry. Control of applying of these standards is still open question. Factory laboratories regardless their equipping are not formally authorized to perform analysis for purposes other than those for their own needs. With establishing of Accrediting Institute of Republic of Macedonia (IARM), and adopting of corresponding regulations, there are conditions for accrediting of laboratories in order of giving services to the State and other users. Subject of this work is accrediting of the laboratory of OKTA - Crude Oil Refinery, Skopje, according the international standard ISO / IEC 17025. Finally this will be beginning of the control of import of crude oil products with suspicious origin and quality, that have been on the Macedonian market for years. (Author)

For Department of Energy (DOE) facilities, compliance with DOE Order 5480.11 became a requirement in January 1989. One of the requirements of this Order is that personal external dosimetry programs be accredited under the Department of Energy's Laboratory Accreditation Program (DOELAP) in Personnel Dosimetry. The accreditation process, from the facility's perspective, is two-fold: dosimeters must meet performance criteria in radiation categories appropriate for each facility, and personnel administering and carrying out the program must demonstrate good operating practices. The DOELAP onsite assessment is designed to provide an independent evaluation of the latter

Air kerma standardization for diagnostic radiology, and requirements proposal for calibration laboratories; Padronizacao da grandeza Kerma no ar para radiodiagnostico e proposta de requisitos para laboratorios de calibracao

Energy Technology Data Exchange (ETDEWEB)

Ramos, Manoel Mattos Oliveira

2009-07-01

The demand for calibration services and quality control in diagnostic radiology has grown in the country since the publication of the governmental regulation 453, issued by the Ministry of Health in 1998. At that time, to produce results facing the new legislation, many laboratories used different standards and radiation qualities, some of which could be inadequate. The international standards neither supplied consistent radiation qualities and standardization for the different types of equipment available. This situation changed with the publication of the new edition of the IEC 61267 standard, published in 2005. A metrology network was created, but it is not yet accredited by the accreditation organism of the country, INMETRO. The objective of this work was to implement the standardization of the air kerma for the un attenuated qualities (RQR) of IEC 61267, and to develop a requirement proposal for instruments calibration laboratories. Results of interlaboratory comparisons demonstrate that the quantity is standardized and internationally traceable. A laboratory requirement proposal was finalized and it shall be submitted to INMETRO to be used as auxiliary normative document in laboratory accreditation. (author)

Since 2003 when the international norm for implementation of quality management in medical laboratories (EN ISO 15189, Medical laboratories--Particular requirements for quality and competence) was established and accepted, accreditation has become practical, generally accepted method of quality management and confirmation of technical competence of medical laboratories in the whole world. This norm has been translated into Croatian and accepted by the Croatian Institute for Norms as Croatian norm. Accreditation is carried out on voluntary basis by the Croatian Accreditation Agency that has up to now accredited two clinical medical biochemical laboratories in the Republic of Croatia. Advantages of accredited laboratory lie in its documented management system, constant improvement and training, reliability of test results, establishing users' trust in laboratory services, test results comparability and interlaboratory (international) test results acceptance by adopting the concept of metrological traceability in laboratory medicine.

It is presumed that echocardiographic laboratory accreditation leads to improved quality, but there are few data. We sought to compare the quality of echocardiographic examinations performed at accredited versus nonaccredited laboratories for the evaluation of valvular heart disease. We enrolled 335 consecutive valvular heart disease subjects who underwent echocardiography at our institution and an external accredited or nonaccredited institution within 6 months. Completeness and quality of echocardiographic reports and images were assessed by investigators blinded to the external laboratory accreditation status and echocardiographic results. Compared with nonaccredited laboratories, accredited sites more frequently reported patient sex (94% versus 78%; P heart disease. Future quality improvement initiatives should highlight the importance of high-quality color Doppler imaging and echocardiographic quantification to improve the accuracy, reproducibility, and quality of echocardiographic studies for valvular heart disease. © 2017 American Heart Association, Inc.

Full Text Available Background: Laboratory services are essential at all stages of the tuberculosis care cascade, from diagnosis and drug resistance testing to monitoring response to treatment. Enabling access to quality services is a challenge in low-resource settings. Implementation of a strong quality management system (QMS and laboratory accreditation are key to improving patient care. Objectives: The study objective was to determine the status of QMS implementation and progress towards accreditation of National Tuberculosis Reference Laboratories (NTRLs in the African Region. Method: An online questionnaire was administered to NTRL managers in 47 World Health Organization Regional Office for Africa member states in the region, between February and April 2015, regarding the knowledge of QMS tools and progress toward implementation to inform strategies for tuberculosis diagnostic services strengthening in the region. Results: A total of 21 laboratories (43.0% had received SLMTA/TB-SLMTA training, of which 10 had also used the Global Laboratory Initiative accreditation tool. However, only 36.7% of NTRLs had received a laboratory audit, a first step in quality improvement. Most NTRLs participated in acid-fast bacilli microscopy external quality assurance (95.8%, although external quality assurance for other techniques was lower (60.4% for first-line drug susceptibility testing, 25.0% for second-line drug susceptibility testing, and 22.9% for molecular testing. Barriers to accreditation included lack of training and accreditation programmes. Only 28.6%of NTRLs had developed strategic plans and budgets which included accreditation. Conclusion: Good foundations are in place on the continent from which to scale up accreditation efforts. Laboratory audits should be conducted as a first step in developing quality improvement action plans. Political commitment and strong leadership are needed to drive accreditation efforts; advocacy will require clear evidence of patient

Uytun, A.; Kalemci, M.

2017-11-01

The number of accredited laboratories in the field of calibration of temperature-controlled enclosures has been increasing in Turkey. One of the main criteria demonstrating the competence of a calibration laboratory is successful participation in interlaboratory comparisons. Therefore, TUBITAK UME Temperature Laboratory organized the first interlaboratory comparison on "Calibration of Temperature-Controlled Enclosures" in Turkey as a pilot laboratory between January and November, 2013. Forty accredited laboratories which provide routine calibration services to the industry in this field participated in the comparison. The standards used during the comparison was a climatic chamber for the measurements at -40 {°}C, -20 {°}C, 40 {°}C and 100 {°}C and an oven for the measurements at 200 {°}C. The protocol of the comparison was prepared considering guide EURAMET cg-20 and BS EN/IEC standards 600068-3-5 and 600068-3-11. During the comparison measurements, each participant had the liberty to choose the most convenient calibration points in terms of their accreditation scope among the values mentioned above and carried out on-site measurements at UME. The details and the results of this comparison are given in the paper. Determination of the statistical consistency of the results with the uncertainties given by the participants can be assessed by the method of En value assessment for each laboratory. En values for all measurement results based on the results of pilot and participating laboratories were calculated.

The World Health Organization Regional Office for Africa (WHO AFRO) introduces a step wise incremental accreditation approach to improving quality of laboratory and it is a new initiative in Ethiopia and activities are performed for implementation of accreditation program. Descriptive cross sectional study was conducted in 30 laboratory facilities including 6 laboratory sections to determine their status towards of accreditation using WHO AFRO accreditation checklist and 213 laboratory professionals were interviewed to assess their knowledge on quality system essentials and accreditation in Addis Ababa Ethiopia. Out of 30 laboratory facilities 1 private laboratory scored 156 (62%) points, which is the minimum required point for WHO accreditation and the least score was 32 (12.8%) points from government laboratory. The assessment finding from each section indicate that 2 Clinical chemistry (55.2% & 62.8%), 2 Hematology (55.2% & 62.8%), 2 Serology (55.2% & 62.8%), 2 Microbiology (55.2% & 62.4%), 1 Parasitology (62.8%) & 1 Urinalysis (61.6%) sections scored the minimum required point for WHO accreditation. The average score for government laboratories was 78.2 (31.2%) points, of these 6 laboratories were under accreditation process with 106.2 (42.5%) average score, while the private laboratories had 71.2 (28.5%) average score. Of 213 respondents 197 (92.5%) professionals had a knowledge on quality system essentials whereas 155 (72.8%) respondents on accreditation. Although majority of the laboratory professionals had knowledge on quality system and accreditation, laboratories professionals were not able to practice the quality system properly and most of the laboratories had poor status towards the WHO accreditation process. Thus government as well as stakeholders should integrate accreditation program into planning and health policy.

Quality management and accreditation in a mixed research and clinical hair testing analytical laboratory setting-a review.

Fulga, Netta

2013-06-01

Quality management and accreditation in the analytical laboratory setting are developing rapidly and becoming the standard worldwide. Quality management refers to all the activities used by organizations to ensure product or service consistency. Accreditation is a formal recognition by an authoritative regulatory body that a laboratory is competent to perform examinations and report results. The Motherisk Drug Testing Laboratory is licensed to operate at the Hospital for Sick Children in Toronto, Ontario. The laboratory performs toxicology tests of hair and meconium samples for research and clinical purposes. Most of the samples are involved in a chain of custody cases. Establishing a quality management system and achieving accreditation became mandatory by legislation for all Ontario clinical laboratories since 2003. The Ontario Laboratory Accreditation program is based on International Organization for Standardization 15189-Medical laboratories-Particular requirements for quality and competence, an international standard that has been adopted as a national standard in Canada. The implementation of a quality management system involves management commitment, planning and staff education, documentation of the system, validation of processes, and assessment against the requirements. The maintenance of a quality management system requires control and monitoring of the entire laboratory path of workflow. The process of transformation of a research/clinical laboratory into an accredited laboratory, and the benefits of maintaining an effective quality management system, are presented in this article.

Accreditation and radiation protection - the cost or smaller doses and reliable results

International Nuclear Information System (INIS)

Omahen, G.; Zdesar, U.

2011-01-01

Laboratories involved in the protection against radiation and therefore in the measurement of radioactivity, dose rate and contamination have always been tied to the quality of their measurements, particularly those that have performed measurements for nuclear power plants. However in the laboratories more than quality it was more important, that people are professional, that they are engaged in scientific work and know how to interpret the results. Very often these are things that do not go along with reviewing the measuring instruments and quality records. However customer requires measurement results that can be trusted. This is the purpose of the standard SIST EN ISO / IEC 17025 in which the requirements for testing and calibration laboratories are standardised. The standard in force since 1999. In some countries, requests for accreditation of testing laboratories according to SIST EN ISO / IEC 17025 is even in regulation. This request is for example in the Croatian and Slovenian regulations for laboratories involved in measuring the radioactivity, dose rate, contamination, or by checking the X-ray apparatus. Several laboratories have been accreditation for several years. From that experience we can conclude that customer gets reliable results from the accredited laboratories at relatively low cost. On the other side laboratory which his accredited has introduced a line of work and his laboratory, there are rules for equipment, personnel, training and all that eventually enhanced measurement expertise. With accreditation, it is much easier to compensate for the loss of workers due to pension or leaving the laboratory because every moment must always be in the laboratory at least two who know how to work on the method. Accreditation is not improving radiation protection or reducing Becquerel in the air. But at least we know how accurate mSv or Bq are and how small mSv and Bq can be measured. (author) [sr

2010-01-01

Medical laboratories, and specifically genetic testing laboratories, provide vital medical services to different clients: clinicians requesting a test, patients from whom the sample was collected, public health and medical-legal instances, referral laboratories and authoritative bodies. All expect results that are accurate and obtained in an efficient and effective manner, within a suitable time frame and at acceptable cost. There are different ways of achieving the end results, but compliance with International Organization for Standardization (ISO) 15189, the international standard for the accreditation of medical laboratories, is becoming progressively accepted as the optimal approach to assuring quality in medical testing. We present recommendations and strategies designed to aid genetic testing laboratories with the implementation of a quality management system, including key aspects such as document control, external quality assessment, internal quality control, internal audit, management review, validation, as well as managing the human side of change. The focus is on pragmatic approaches to attain the levels of quality management and quality assurance required for accreditation according to ISO 15189, within the context of genetic testing. Attention is also given to implementing efficient and effective quality improvement. PMID:20720559

Accreditation to ISO/IEC 17025 is required for EC official food control and veterinary laboratories by Regulation (EC) No. 882/2004. Measurements in hospital laboratories and clinics are increasingly accredited to ISO/IEC 15189. Both of these management standards arose from command and control military standards for factory inspection during World War II. They rely on auditing of compliance and have not been validated internally as assessment bodies require of those they accredit. Neither have they been validated to criteria outside their own ideology such as the Cochrane principles of evidence-based medicine which might establish whether any benefit exceeds their cost. We undertook a retrospective meta-audit over 14 years of internal and external laboratory audits that checked compliance with ISO 17025 in a public health laboratory. Most noncompliances arose solely from clauses in the standard and would not affect users. No effect was likely from 91% of these. Fewer than 1% of noncompliances were likely to have consequences for the validity of results or quality of service. The ISO system of compliance auditing has the performance characteristics of a poor screening test. It adds substantially to costs and generates more noise (false positives) than informative signal. Ethical use of resources indicates that management standards should not be used unless proven to deliver the efficacy, effectiveness, and value required of modern healthcare interventions. © 2015 The Authors.

Lee, B.T.; Hwang, W.S.; Su, S.H.

2000-01-01

According to the ionizing radiation safety regulation approved by the ROC Atomic Energy Council (AEC), personnel dosimeter processors shall be accredited by the Chinese National Laboratory Accreditation (CNLA) program before offering dosimeter services and shall be accredited every two years (now has been rescheduled to be every three years since 1996). The aim of this program is to secure quality and technical capability of personnel dosimeters, and to provide systematic improvement for the internal calibration and testing laboratory applying for accreditation by means of assessment procedures. The criteria used to evaluate the capability at laboratories are ISO/IEC 25 (1990) and technical guide in different accreditation fields. The Institute of Nuclear Energy Research (INER) was entrusted by CNLA as the central laboratory to perform the proficiency test of personnel dosimeters for laboratory accreditation in December 1990. Such proficiency tests, based on ANSI N13.11 (1983), which is mainly separated to accident categories and protection categories which consists of eight parts of tests including single and mixture radiation of x-ray, gamma, beta and neutron, have been conducted four times, in 1991, 1993, 1995 and 1998. This paper deals with the test procedures and results of proficiency tests of personnel dosimeters from 1991 until 1998. The results of the four proficiency tests showed that, for accident categories, the pass rate is about 91%; for protection categories, the pass rate is about 98%. Meanwhile, the central laboratory will adopt a new version of HPS N13.11 (1993) to replace ANSI N13.11 (1983) as new criteria for the next proficiency test to be conducted in 2001. (author)

The calibrations laboratory at Pacific Northwest Laboratory (PNL) serves as a radiological standardization facility for personnel and environmental dosimetry and radiological survey instruments. As part of this function, the calibrations laboratory must maintain radiological reference fields with calibrations traceable to the National Institute of Standards and Technology (NIST). This task is accomplished by a combination of (1) sources or reference instruments calibrated at or by NIST, (2) measurement quality assurance (MQA) interactions with NIST, and (3) rigorous internal annual and quarterly calibration verifications. This paper describes a representative sample of the facilities, sources, and actions used to maintain accurate and traceable fields

Accreditation and Radiation Protection - Do We Need It Because of the Law or Because of Us

Laboratories involved in the protection against radiation and therefore in the measurement of radioactivity, dose rate and contamination have always been tied to the quality of their measurements, particularly those that have performed measurements for nuclear power plants. However in the laboratories more than quality it was more important, that people are professional, that they are engaged in scientific work and know how to interpret the results. Very often these are things that do not go along with reviewing the measuring instruments and quality records. However customer requires measurement results that can be trusted. This is the purpose of the standard SIST EN ISO / IEC 17025 in which the requirements for testing and calibration laboratories are standardised. The standard is in force since 1999. In some countries, a request for accreditation of testing laboratories according to SIST EN ISO / IEC 17025 is even in regulation. This request is for example in the Croatian and Slovenian regulations for laboratories involved in measuring the radioactivity, dose rate, contamination, or by checking the X-ray apparatus. Several laboratories have been accredited for several years. From that experience we can conclude that customer gets reliable results from the accredited laboratories at relatively low cost. On the other side laboratory which is accredited has introduced a line of work in the laboratory, there are rules for equipment, personnel, training and all that eventually enhance measurement expertise. With accreditation, it is much easier to compensate for the loss of workers due to pension or leaving the laboratory because every moment must always be in the laboratory at least two who know how to work on the method. Accreditation is not improving radiation protection or reducing becquerel in the air. But at least we know how accurate mSv or Bq are and how small mSv and Bq can be measured. (author)

Role and Evaluation of Interlaboratory Comparison Results in Laboratory Accreditation

Science.gov (United States)

Bode, P.

2008-08-01

Participation in interlaboratory comparisons provides laboratories an opportunity for independent assessment of their analytical performance, both in absolute way and in comparison with those by other techniques. However, such comparisons are hindered by differences in the way laboratories participate, e.g. at best measurement capability or under routine conditions. Neutron activation analysis laboratories, determining total mass fractions, often see themselves classified as `outliers' since the majority of other participants employ techniques with incomplete digestion methods. These considerations are discussed in relation to the way results from interlaboratory comparisons are evaluated by accreditation bodies following the requirements of Clause 5.9.1 of the ISO/IEC 17025:2005. The discussion and conclusions come largely forth from experiences in the author's own laboratory.

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

Full Text Available Accreditation of a laboratory is verification of the competence of a laboratory regarding methods and procedures applied, personnel, the equipment used and working conditions. The main goal is establishment of customer trust in accuracy and precision of laboratory test results. Accredited laboratory has more specific costs than laboratory which is not accredited. To survive on the market, regardless the laboratory is independent or it is a part of a bigger system, the laboratory needs to establish resource management, especially effective cost management. Cost management describes approaches and short-term and long-term management activities, which make value for the customer, according to his known, reported or obligatory requirements and needs. In modern approach, there are different methods for cost calculation. One of them is ABC (Activity-Based Costing method which adds activity costs to products and services trough activities needed for their finalization. In this paper, there is presented improved ABC method for obračun costs, affirmed as activity based cost calculation based on time - TD ABC (Time-Driven Activity-Based Costing. The method uses time as a primary base for costs allocation on products, porudžbine, customers. This is the way for simpler and less expansive getting of information's about costs. This paper describes TD ABC method implemented in accredited Laboratory for physical and chemical testing, which is a part of company Galenika Fitofarmacija a.d. The scope of testing in this laboratory are pesticide materials, meaning technical substances and finished products, within quality control for different internal customers. By using TD ABC method it is possible to define real costs, generated during the laboratory testing, and also effectiveness of specific activities in this process.

Pirchio, R.; Saravi, M.

2006-01-01

A common practice in quality control programs for dosimetry in brachytherapy is the source calibration. The AAPM (American Association of Physicists in Medicine) in the Task Group No. 40 (TG-40) it recommends that each institution that offers a brachytherapy service verifies the intensity of each source provided by the maker with secondary traceability. For such a reason it is necessary to have laboratories able to make calibrations of sources, traceable electrometer-chambers to primary or credited laboratories. The Regional Center of Reference of Dosimetry of the CNEA (National Commission of Atomic Energy) it is in the stage of finalization of the assembly of a Laboratory for source calibration and use equipment in brachytherapy. For it has two ionization chambers well type and two electrometers gauged by the Accredited Dosimetry Calibration Laboratory of the University of Wisconsin. Also account with a wide variety of supports and with a tube of 137 Cs pattern 3M model 6500/6D6C. The procedures for the calibration of sources and equipment were elaborated starting from the TECDOC-1274. On the other hand, its were carried out measurements with different instrumentation for the comparison of responses and at the same time to implement the calibration procedures. For it, its were used chambers and electrometers of the institution, of hospitals and of the national company 'Solydes'. In the measurements its were used seeds of 125 I taken place in Argentina and the tube of 137 Cs pattern mentioned previously. In first place it was proceeded to the determination of the center of the region of the plateau in the axial response for the seeds of Iodine-125 and the tube of Cesium-137 pattern using different chambers. Later on its were carried out measurements of accumulated loads during a certain interval of time in this position. The calibration factors of each chamber were determined, N Sk (μGy m 2 h -1 A -1 ), as the quotient of the kerma rate in reference air of the

The public institution aims to promote excellence in public management to contribute to the quality of services provided to its customers and to increase competitiveness in the country, as well as its international projection. A technical barrier to trade that can lead to dissatisfaction and achieve the reputation of the institution is failing the test or calibration results and measurement data, thereby accreditation is regarded as the first essential step to facilitate the mutual acceptance of test results and calibration or measurement data. For recognition, laboratories need to demonstrate full compliance with both the sections of ISO/IEC 17025:2005, i.e. management and technical requirements. This research aims to discuss the critical aspects for implementation of ABNT NBR ISO / IEC 17025:2005 for calibration and testing of a Public Institution seeking accreditation of its laboratories with INMETRO, national accreditation body Laboratories. Besides getting preventive, corrective and improvement actions continues guidelines. Furthermore, the methodology used was to conduct a literature search and apply a questionnaire to identify the degree of agreement / disagreement of the foundations of the standard servers. Analysis of the results showed that the critical issues were: commitment, training, resources (infrastructure, human) and culture. (author)

Alpizar Herrera, Juan Carlos

2014-01-01

A survey was conducted to quantify the need for calibration of a density measurement instrument at the research units at the Sede Rodrigo Facio of the Universidad de Costa Rica. A calibration procedure was documented for the instrument that presented the highest demand in the survey by the calibration service. A study of INTE-ISO/IEC 17025: 2005 and specifically in section 5.4 of this standard was done, to document the procedure for calibrating densimeters. Densimeter calibration procedures and standards were sought from different national and international sources. The method of hydrostatic weighing or Cuckow method was the basis of the defined procedure. Documenting the calibration procedure and creating other documents was performed for data acquisition log, intermediate calculation log and calibration certificate copy. A veracity test was performed using as reference laboratory a laboratory of calibration secondary national as part of the validation process of the documented procedure. The results of the E_n statistic of 0.41; 0.34 and 0.46 for the calibration points 90%, 50% and 10% were obtained for the densimeter scale respectively. A reproducibility analysis of the method was performed with satisfactory results. Different suppliers were contacted to estimate the economic costs of the equipment and materials, needed to develop the documented method of densimeter calibration. The acquisition of an analytical balance was recommended, instead of a precision scale, in order to improve the results obtained with the documented method [es

Characterization of a 137Cs standard source for calibration purposes at CRCN-NE

Oliveira, Mercia L.; Santos, Marcus A.P. dos; Benvides, Clayton A.

2008-01-01

Radiation protection monitoring instruments should be calibrated by accredited calibration laboratories. To offer calibration services, a laboratory must accomplish all requirements established by the national regulatory agency. The Calibration Service of the Centro Regional de Ciencias Nucleares (CRCN-NE), Comissao Nacional de Energia Nuclear, Recife, Brazil, is trying to achieve this accreditation. In the present work, a 137 Cs standard source was characterized following the national and international recommendations and the results are presented. This source is a commercially available single source irradiator model 28-8A, manufactured by J.L. Shepherd and Associates, with initial activity of 444 GBq (05/13/03). To provide different air kerma rates, as required for the calibration of portable radiation monitors, this irradiator have a set of four lead attenuators with different thickness, providing attenuation factors equal to 2, 4, 10 and 100 times (nominally). The performed tests included: size and uniformity of the radiation standard field at calibration reference position, variation of the air kerma rate for different lead attenuators, determination of attenuation factors for each lead attenuator configuration, and determination of the radiation scattering at the calibration reference position. The results showed the usefulness of the 137 Cs standard source for the calibration of radiation protection monitoring detectors. (author)

Solid laboratory calibration of a nonimaging spectroradiometer.

Science.gov (United States)

Schaepman, M E; Dangel, S

2000-07-20

Field-based nonimaging spectroradiometers are often used in vicarious calibration experiments for airborne or spaceborne imaging spectrometers. The calibration uncertainties associated with these ground measurements contribute substantially to the overall modeling error in radiance- or reflectance-based vicarious calibration experiments. Because of limitations in the radiometric stability of compact field spectroradiometers, vicarious calibration experiments are based primarily on reflectance measurements rather than on radiance measurements. To characterize the overall uncertainty of radiance-based approaches and assess the sources of uncertainty, we carried out a full laboratory calibration. This laboratory calibration of a nonimaging spectroradiometer is based on a measurement plan targeted at achieving a calibration. The individual calibration steps include characterization of the signal-to-noise ratio, the noise equivalent signal, the dark current, the wavelength calibration, the spectral sampling interval, the nonlinearity, directional and positional effects, the spectral scattering, the field of view, the polarization, the size-of-source effects, and the temperature dependence of a particular instrument. The traceability of the radiance calibration is established to a secondary National Institute of Standards and Technology calibration standard by use of a 95% confidence interval and results in an uncertainty of less than ?7.1% for all spectroradiometer bands.

Implementing quality management systems and accrediting laboratories in the Caribbean has been a challenge. We report the development of a stepwise process for quality systems improvement in the Caribbean Region. The Caribbean Laboratory Stakeholders met under a joint Pan American Health Organization/US Centers for Disease Control and Prevention initiative and developed a user-friendly framework called 'Laboratory Quality Management System - Stepwise Improvement Process (LQMS-SIP) Towards Accreditation' to support countries in strengthening laboratory services through a stepwise approach toward fulfilling the ISO 15189: 2012 requirements. This approach consists of a three-tiered framework. Tier 1 represents the minimum requirements corresponding to the mandatory criteria for obtaining a licence from the Ministry of Health of the participating country. The next two tiers are quality improvement milestones that are achieved through the implementation of specific quality management system requirements. Laboratories that meet the requirements of the three tiers will be encouraged to apply for accreditation. The Caribbean Regional Organisation for Standards and Quality hosts the LQMS-SIP Secretariat and will work with countries, including the Ministry of Health and stakeholders, including laboratory staff, to coordinate and implement LQMS-SIP activities. The Caribbean Public Health Agency will coordinate and advocate for the LQMS-SIP implementation. This article presents the Caribbean LQMS-SIP framework and describes how it will be implemented among various countries in the region to achieve quality improvement.

When a laboratory wants to prove that he has technical competence to carry out tests or calibrations must demonstrate that it has complied with certain requirements that establish , among others, the mandatory : calibrate or verify equipment before putting it into service in order to ensure that it meets to the specifications of laboratory equipment to keep records evidencing the checks that equipment complies with the specification ; perform intermediate checks for maintain confidence in the calibration status of the equipment , ensure that the operation is checked and calibration status of equipment when the equipment goes outside the direct control of the laboratory , before be returned to service, establish a program and procedure for the calibration of equipment; show how determined the calibration periods of their equipment as well as evidence that intermediate checks are suitable for the calibration periods. However, some confusion is observed as to the meaning of the terms 'calibration' and 'verification' of a computer. This paper analyzes applicable documentation and suggests that the differences are generated in part by translations and by characterization concepts upon its usage, that is, if it is legal metrology or assessment conformity. Therefore, this study aims to characterize both concepts , fundamentals to zoom distinguish , outline appropriate strategies for calibration and verification activities to ensure the compliance with regulatory requirements [es

Therefore, the accredited laboratory starts, respectively, taking part from the Brazilian Calibration Network (RBC) or from the Brazilian Testing Laboratories Network (RBLE) . The Environmental Radioanalysis Division (DIAMB) from Environmental Radiological Protection Department (DEPRA) from Institute of Radiation Protection and Dosimetry (IRD) from Brazilian National Nuclear Energy Commission (CNEN) is a laboratory responsible for analyzing radionuclides deriving for the samples from DEPRA's Surveillance Program, research and servings, due to an eventual radionuclide contamination in environment, foods and others raw materials for human consumption; including for importation and exportation products certification purposes. For all these reasons, DIAMB needs its formal recognition for carrying out radionuclides analysis in environmental samples. This work aims to provide a methodology in order to guide a laboratory which has the intention to implement a accreditation process. It also describes policies to meet the requirements related to the Standard, guidance needed to specification of some steps and also comments some points from the Standard in order to become easier all the accreditation process comprehension.

Over recent years, the development of molecular biology techniques has improved the hematological diseases diagnostic and follow-up. Consequently, these techniques are largely used in the biological screening of these diseases; therefore the Hemato-oncology molecular diagnostics laboratories must be actively involved in the accreditation process according the ISO 15189 standard. The French group of molecular biologists (GBMHM) provides requirements for the implementation of quality assurance for the medical molecular laboratories. This guideline states the recommendations for the pre-analytical, analytical (methods validation procedures, quality controls, reagents), and post-analytical conditions. In addition, herein we state a strategy for the internal quality control management. These recommendations will be regularly updated.

Photovoltaic Device Performance Evaluation Using an Open-Hardware System and Standard Calibrated Laboratory Instruments

Directory of Open Access Journals (Sweden)

Jesús Montes-Romero

2017-11-01

Full Text Available This article describes a complete characterization system for photovoltaic devices designed to acquire the current-voltage curve and to process the obtained data. The proposed system can be replicated for educational or research purposes without having wide knowledge about electronic engineering. Using standard calibrated instrumentation, commonly available in any laboratory, the accuracy of measurements is ensured. A capacitive load is used to bias the device due to its versatility and simplicity. The system includes a common part and an interchangeable part that must be designed depending on the electrical characteristics of each PV device. Control software, developed in LabVIEW, controls the equipment, performs automatic campaigns of measurements, and performs additional calculations in real time. These include different procedures to extrapolate the measurements to standard test conditions and methods to obtain the intrinsic parameters of the single diode model. A deep analysis of the uncertainty of measurement is also provided. Finally, the proposed system is validated by comparing the results obtained from some commercial photovoltaic modules to the measurements given by an independently accredited laboratory.

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

Bhatt, Anita

2016-01-01

The Quality Assurance for analytical measurement of internal radioactive contamination and dose assessment in the United States (US) is achieved through the US Department of Energy (DOE) Laboratory Accreditation Program (DOELAP) for both Dosimetry and Radio bioassay laboratories for approximately 150,000 radiation workers. This presentation will explain the link between Quality Assurance and the DOELAP Accreditation process. DOELAP is a DOE complex-wide safety program that ensures the quality of worker radiation protection programs. DOELAP tests the ability of laboratories to accurately measure and quantify radiation dose to workers and assures the laboratories quality systems are capable of defending and sustaining their measurement results. The United States Law in Title 10 of the Code of Federal Regulations 835 requires that personnel Dosimetry and Radio bioassay programs be tested and accredited

The national temperature standard for the low-temperature range between 13.8033 K and 273.16 K has been established in Poland at the Institute of Low Temperature and Structure Research (INTiBS). The standard consists of sealed cells for realization of six fixed points of the International Temperature Scale of 1990 (ITS-90) in the low-temperature range, an adiabatic cryostat and Isotech water and mercury triple-point baths, capsule standard resistance thermometers (CSPRT), and AC and DC bridges with standard resistors for thermometers resistance measurements. INTiBS calibrates CSPRTs at the low-temperature fixed points with uncertainties less than 1 mK. In lower temperature range—between 2.5 K and about 25 K — rhodium-iron (RhFe) resistance thermometers are calibrated by comparison with a standard which participated in the EURAMET.T-K1.1 comparison. INTiBS offers a calibration service for industrial platinum resistance thermometers and for digital thermometers between 77 K and 273 K. These types of thermometers may be calibrated at INTiBS also in a higher temperature range up to 550°C. The Laboratory of Temperature Standard at INTiBS acquired an accreditation from the Polish Centre for Accreditation. A management system according to EN ISO/IEC 17025:2005 was established at the Laboratory and presented on EURAMET QSM Forum.

Accredition: An accredited utility's perspective

International Nuclear Information System (INIS)

Jambrovic, H.

1990-01-01

Accredition is a quality assurance program that applies to electricity billing meters. Under the Electricity and Gas Inspection Act, an electricity meter is not a legal billing device until a prototype has been scrutinized and approved for use by Consumer and Corporate Affairs Canada (CCAC) laboratories, and a meter cannot be used for billing purposes unless its accuracy and condition have been inspected and the meter is sealed to prevent tampering. In 1986 an ammendment to the act allowed accredited organizations to inspect, verify and seal their own billing meters. Ontario Hydro embarked on a program to become accredited in 1987, to offset spiraling government inspection fees in the order of $500,000/y, and to be less dependent on the availability of government inspectors. Ontario Hydro achieved accredition status two years after embarking on the program, which involved completion of cost benefit analysis, securing senior management commitment, preparation of a comprehensive quality assurance program manual, implementation of quality assurance program policies, procedures and controls, submitting meter shop operations and field meter handling practices to both internal Ontario Hydro and external government audit, and correction of audit findings. 2 figs

Calibration of quality control (QC) test tools used in diagnostic radiology is legally required under the Ministry of Health (MOH) requirement. The Medical Physics Calibration Laboratory of the Malaysian Nuclear Agency is the national focal point for the calibration of quality control test tools used in diagnostic radiology. The Medical Physics Calibration Laboratory has measurement traceability to primary standard dosimetry laboratory (Physikalisch-Technische Bundesanstalt (PTB)), thus providing an interface between the primary standard dosimetry laboratory and Malaysian hospitals, clinics and license class H holder. The Medical Physics Calibration Laboratory facility is comprised of a constant potential x-ray system with a capability of 160 kV tube and a series of reference and working standard ion chambers. The stability of reference and working standard ion chambers was measured using strontium-90. Dosimetric instruments used in diagnostic radiology is calibrated in terms of air kerma to comply with an International Code of Practices of dosimetry for example IAEA's Technical Report Series number 457. The new series of standard radiation qualities was established based on ISO/IEC 61267. The measurement of beam homogeneity was measured using film and ion chamber to define the field size at certain distance and kV output was measured using the spectrometer and non-invasive kVp meter. The uncertainties measurement was determined with expended uncertainties to a level of confidence of approximately 95% (coverage factor k=2). This paper describes the available facility and the effort of the Medical Physics Calibration Laboratory to upgrade the laboratory towards ISO/IEC 17025. (author)

The US Department of Energy (DOE) Office of Nuclear Safety has developed and initiated the DOE Laboratory Accreditation Program (DOELAP) for personnel dosimetry systems to assure and improve the quality of personnel dosimetry at DOE and DOE contractor facilities. It consists of a performance evaluation program that measures current performance and an applied research program that evaluates and recommends additional or improved test and performance criteria. It also provides guidance to DOE, identifying areas where technological improvements are needed. The two performance evaluation elements in the accreditation process are performance testing and onsite assessment by technical experts. Performance testing evaluates the participant's ability to accurately and reproducibly measure dose equivalent. Tests are conducted in accident level categories for low- and high-energy photons as well as protection level categories for low- and high-energy photons, beta particles, neutrons and mixtures of these

The role of the EPA radiation quality assurance program in the measurement quality assurance accreditation program for radioassay laboratories

Energy Technology Data Exchange (ETDEWEB)

Grady, T.M. [Environmental Monitoring Systems Laboratory, Las Vegas, NV (United States)

1993-12-31

As the nature and extent of radiological contamination becomes better documented and more public, radioanalytical laboratories are faced with a constantly expanding variety of new and difficult analytical requirements. Concurrent with those requirements is the responsibility to provide customers, regulatory officials, or the public with defensible data produced in an environment of verifiable, controlled quality. To meet that need, a quality assurance accreditation program for radioassay laboratories has been proposed by the American National Standards Institute (ANSI). The standard will provide the organizational framework and functional requirements needed to assure the quality of laboratory outputs. Under the proposed program, the U.S. Environmental Protection Agency`s (EPA`s) Laboratory Intercomparison Program plays a key role as a reference laboratory. The current and proposed roles of the EPA Intercomparison Program are discussed, as are the functional relationships between EPA, the accreditating organization, and the service and monitoring laboratories.

CERN radiation protection (RP) calibration facilities

Energy Technology Data Exchange (ETDEWEB)

Pozzi, Fabio

2016-04-14

Radiation protection calibration facilities are essential to ensure the correct operation of radiation protection instrumentation. Calibrations are performed in specific radiation fields according to the type of instrument to be calibrated: neutrons, photons, X-rays, beta and alpha particles. Some of the instruments are also tested in mixed radiation fields as often encountered close to high-energy particle accelerators. Moreover, calibration facilities are of great importance to evaluate the performance of prototype detectors; testing and measuring the response of a prototype detector to well-known and -characterized radiation fields contributes to improving and optimizing its design and capabilities. The CERN Radiation Protection group is in charge of performing the regular calibrations of all CERN radiation protection devices; these include operational and passive dosimeters, neutron and photon survey-meters, and fixed radiation detectors to monitor the ambient dose equivalent, H*(10), inside CERN accelerators and at the CERN borders. A new state-of-the-art radiation protection calibration facility was designed, constructed and commissioned following the related ISO recommendations to replace the previous ageing (more than 30 years old) laboratory. In fact, the new laboratory aims also at the official accreditation according to the ISO standards in order to be able to release certified calibrations. Four radiation fields are provided: neutrons, photons and beta sources and an X-ray generator. Its construction did not only involve a pure civil engineering work; many radiation protection studies were performed to provide a facility that could answer the CERN calibration needs and fulfill all related safety requirements. Monte Carlo simulations have been confirmed to be a valuable tool for the optimization of the building design, the radiation protection aspects, e.g. shielding, and, as consequence, the overall cost.

At the annual meeting of the Society of Hair Testing in Vadstena, Sweden in 2006, a committee was appointed to address the issue of guidelines for hair testing and to assess the current status of accreditation amongst laboratories offering drug testing in hair. A short questionnaire was circulated amongst the membership and interested parties. Fifty-two responses were received from hair testing laboratories providing details on the amount and type of hair tests they offered and the status of accreditation within their facilities. Although the vast majority of laboratories follow current guidelines (83%), only nine laboratories were accredited to ISO/IEC 17025 for hair testing. A significant number of laboratories reporting that they were in the process of developing quality systems with a view to accrediting their methods within 2-3 years. This study provides an insight into the status of accreditation in hair testing laboratories and supports the need for guidelines to encourage best practice.

ISO 15189 Accreditation: Navigation Between Quality Management and Patient Safety

Directory of Open Access Journals (Sweden)

Plebani Mario

2017-09-01

Full Text Available Accreditation is a valuable resource for clinical laboratories and the development of an International Standard for their accreditation represented a milestone on the path towards improved quality and safety in laboratory medicine. The recent revision of the International Standard, ISO 15189, has further strengthened its value not only for improving the quality system of a clinical laboratory but also for better answering the request for competence, focus on customers’ needs and ultimate value of laboratory services. Although in some countries more general standards such as ISO 9001 for quality systems or ISO 17025 for testing laboratories are still used, there is increasing recognition of the value of ISO 15189 as the most appropriate and useful standard for the accreditation of medical laboratories. In fact, only this International Standard recognizes the importance of all steps of the total testing process, namely extra-analytical phases, the need to focus on technical competence in addition to quality systems, and the focus on customers’ needs. However, the number of accredited laboratories largely varies between European countries and also major differences affect the approaches to accreditation promoted by the national bodies. In particular, some national accreditation bodies perpetuate the use of fixed scopes, while the European co-operation for accreditation (EA and the European Federation of Laboratory Medicine (EFLM Working Group promote the use of flexible scopes. Major issues in clinical laboratory accreditation are the verification of examination procedures for imprecision, trueness and diagnostic accuracy and for estimating measurement uncertainty. In addition, quality indicators (QIs are a fundamental requirement of the ISO 15189 International Standard.

Photon contributions from the 252Cf and 241Am–Be neutron sources at the PSI Calibration Laboratory

At the accredited PSI Calibration Laboratory neutron reference fields traceable to the national standards of the Physikalisch-Technische Bundesanstalt (PTB) in Germany are available for the calibration of ambient and personal dose equivalent (rate) meters and passive dosimeters. The photon contribution to the ambient dose equivalent in the neutron fields of the 252 Cf and 241 Am–Be sources was measured using various photon dose rate meters and active and passive dosimeters. Measuring photons from a neutron source usually involves considerable uncertainties due to the presence of neutron induced photons in the room, due to a non-zero neutron sensitivity of the photon detector, and last but not least due to the energy response of the photon detectors. Therefore eight independent detectors and methods were used to obtain a reliable estimate for the photon contribution of the two sources as an average of the individual methods. For the 241 Am–Be source a photon contribution of approximately 4.9% was determined and for the 252 Cf source a contribution of 3.6%.

Quality Management and Calibration

Science.gov (United States)

Merkus, Henk G.

Good specification of a product’s performance requires adequate characterization of relevant properties. Particulate products are usually characterized by some PSD, shape or porosity parameter(s). For proper characterization, adequate sampling, dispersion, and measurement procedures should be available or developed and skilful personnel should use appropriate, well-calibrated/qualified equipment. The characterization should be executed, in agreement with customers, in a wellorganized laboratory. All related aspects should be laid down in a quality handbook. The laboratory should provide proof for its capability to perform the characterization of stated products and/or reference materials within stated confidence limits. This can be done either by internal validation and audits or by external GLP accreditation.

The most common nonconformities encountered during the assessments of medical laboratories in Hong Kong using ISO 15189 as accreditation criteria.

2012-01-01

ISO 15189 was a new standard published in 2003 for accrediting medical laboratories. We believe that some requirements of the ISO 15189 standard are especially difficult to meet for majority of laboratories. The aim of this article was to present the frequency of nonconformities to requirements of the ISO 15189 accreditation standard, encountered during the assessments of medical laboratories in Hong Kong, during 2004 to 2009. Nonconformities reported in assessments based on ISO 15189 were analyzed in two periods - from 2004 to 2006 and in 2009. They are categorized according to the ISO 15189 clause numbers. The performance of 27 laboratories initially assessed between 2004 and 2006 was compared to their performance in the second reassessment in 2009. For management requirements, nonconformities were most frequently reported against quality management system, quality and technical records and document control; whereas for technical requirements, they were reported against examination procedures, equipment, and assuring quality of examination procedures. There was no major difference in types of common nonconformities reported in the two study periods. The total number of nonconformities reported in the second reassessment of 27 laboratories in 2009 was almost halved compared to their initial assessments. The number of significant nonconformities per laboratory significantly decreased (P = 0.023). Similar nonconformities were reported in the two study periods though the frequency encountered decreased. The significant decrease in number of significant nonconformities encountered in the same group of laboratories in the two periods substantiated that 15015189 contributed to quality improvement of accredited laboratories.

Roberson, P.L.; Campbell, G.W.

1984-11-01

The national laboratories are probable candidates to serve as secondary standards laboratories for the federal sector. Representatives of the major Department of Energy laboratories were polled concerning attitudes toward a secondary laboratory structure. Generally, the need for secondary laboratories was recognized and the development of such a program was encouraged. The secondary laboratories should be reviewed and inspected by the National Bureau of Standards. They should offer all of the essential, and preferably additional, calibration services in the field of radiological health protection. The selection of secondary laboratories should be based on economic and geographic criteria and/or be voluntary. 1 ref., 2 tabs

Proficiency test in the accreditation system

Legarda, F.; Herranz, M.; Idoeta, R.

2008-01-01

In the accreditation process of a radioactivity measurements laboratory, according to ISO standard 17025, proficiency tests play a fundamental role. These PTs constitute an irreplaceable tool for the validation of measuring methods. In the case of Spain, ENAC, which is the Spanish accreditation national body, requires that the laboratory has to take part in a PT for each one of the accredited measuring methods in the period of time between two reassessments of the accreditation, what happens every 4-5 years. In specific areas of determination procedures, among which radioactive measurements could be included, the number of methods which can be accredited is very large. The purpose of the present work is to establish a classification into families of the different radioactivity measurement procedures, as well as to establish complementary actions that guarantee that carrying out periodically proficiency-tests on any of the included procedures in each family, every measurement procedure include in that family is controlled, complying with the criteria established by ENAC

The Calibration Laboratory attempts to provide services that satisfy the needs and requests for a variety of customers. New needs and requests have resulted in calibration of instrumentation outside the original laboratory designs. These tasks require several changes at the laboratory and a need for new support services, especially measurement quality assurance (MQA). The MQA tests are gamma (Cs-137) below 0.5 mrem (5{mu}Sv) per hour and x-ray kVp. Modification to the current gamma (Cs-137) MQA test is recommended because lower intensity fields are commonly measured.

The Laboratory Accreditation Program of the College of American Pathologists (CAP) began in 2015 to allow accredited laboratories to devise their own strategies for quality control of laboratory testing. Participants now have the option to implement individualized quality control plans (IQCPs). Only nonwaived testing that features an internal control (built-in, electronic, or procedural) is eligible for IQCP accreditation. The accreditation checklists that detail the requirements have been peer-reviewed by content experts on CAP's scientific resource committees and by a panel of accreditation participants. Training and communication have been key to the successful introduction of the new IQCP requirements. Copyright © 2016 Elsevier Inc. All rights reserved.

The dose calculation algorithm for a symmetric four-element LiF:Mg,Ti based thermoluminescent dosimeter is presented. The algorithm is based on the parameterization of the response of the dosimeter when exposed to both pure and mixed fields of various types and compositions. The experimental results were then used to develop the algorithm as a series of empirical response functions. Experiments to determine the response of the dosimeter and to test the dose calculation algorithm were performed according to the standard established by the Department of Energy Laboratory Accreditation Program (DOELAP). The test radiation fields include: 137 Cs gamma rays, 90 Sr/ 90 Y and 204 Tl beta particles, low energy photons of 20-120 keV and moderated 252 Cf neutron fields. The accuracy of the system has been demonstrated in an official DOELAP blind test conducted at Sandia National Laboratory. The test results were well within DOELAP tolerance limits. The results of this test are presented and discussed

The Department of Clinical Laboratory, Nagoya University Hospital acquired ISO 15189 accreditation in November, 2009. The operation of our Quality Management System (QMS) was first surveyed in October, 2010. In this paper, we reported the activity for the preparation and operation of our QMS and the effects of ISO 15189 accreditation. We investigated the changes in the number and content on nonconformities, incident reports and complaints before and after accreditation as indicators to evaluate the effect of ISO 15189 accreditation. Post accreditation, the number of nonconformities and incident reports decreased, seeming to show an improvement of quality of the laboratory activity; however, the number of complaints increased. We identified the increase of complaints at the phlebotomy station. There had been some problems with blood sampling in the past, but it seemed that staff had a high level of concern regarding these problems at the phlebotomy station and took appropriate measures to resolve the complaints. We confirmed that the ISO 15189 accreditation was instrumental in the improvements of the safety and efficiency on laboratory works. However there was a problem that increase of overtime works to operate the QMS. We deal with development of a laboratory management system using IT recourses to solve the problem.

The in vivo monitoring laboratory (IVM) at Karlsruhe Institute of Technology (KIT), with one whole body counter and three partial-body counters, is an approved lab for individual monitoring according to German regulation. These approved labs are required to prove their competencies by accreditation to ISO/IEC 17025:2005. In 2007 a quality management system (QMS), which was successfully audited and granted accreditation, was set up at the IVM. The system is based on the ISO 9001 certified QMS of the central safety department of the Research Centre Karlsruhe the IVM belonged to at that time. The system itself was set up to be flexible and could be adapted to the recent organisational changes (e.g. founding of KIT and an institute for radiation research) with only minor effort.

Demand for quality of products and services by consumers throughout the world resulted in fierce competition among manufacturers and service providers. Such a competition forces NDT service providers to deliver the highest quality and most reliable results at a reasonable price to their clients. NDT beneficiaries such as oil and gas, and power generation sectors through their quality system such as ISO 9001 Version 2000 demand that the quality system adopted by organizations providing services to them must be evaluated. Such requirement leave NDT services companies with no option except to have them accredited. As for today, the most logical accreditation scheme applicable to NDT organizations is the ISO 17025. This paper reviews the current status and forecast the need for such an accreditation in Malaysia. (Author)

Nowadays, several types of infusion pump are commonly used for drug delivery, such as syringe pumps and peristaltic pumps. These instruments present different measuring features and capacities according to their use and therapeutic application. In order to ensure the metrological traceability of these flow and volume measuring equipment, it is necessary to use suitable calibration methods and standards. Two different calibration methods can be used to determine the flow error of infusion pumps. One is the gravimetric method, considered as a primary method, commonly used by National Metrology Institutes. The other calibration method, a secondary method, relies on an infusion device analyser (IDA) and is typically used by hospital maintenance offices. The suitability of the IDA calibration method was assessed by testing several infusion instruments at different flow rates using the gravimetric method. In addition, a measurement comparison between Portuguese Accredited Laboratories and hospital maintenance offices was performed under the coordination of the Portuguese Institute for Quality, the National Metrology Institute. The obtained results were directly related to the used calibration method and are presented in this paper. This work has been developed in the framework of the EURAMET projects EMRP MeDD and EMPIR 15SIP03.

The quality control section of Plutonium Fuel Development Center (PFDC) of Japan Atomic Energy Agency has been analyzing isotopic compositions by Mass Spectrometry as well as content by Isotope Dilution Mass Spectrometry (IDMS) of plutonium and uranium in nuclear materials. Along with establishing and managing the quality assurance system, ensuring the reliability of the analysis data is important. PFDC has been establishing the quality management system with ISO9001. ISO9001 consists of management requirements for quality system of organizations. While ISO/IEC 17025 consists of technical requirements for the competence of testing and calibration laboratories in addition to the management requirements. The quality control section addressed technical improvement to improve further reliability of analysis quality and we have accredited for ISO/IEC 17025 of isotopic compositions and content of plutonium and uranium in nuclear materials in March 2010. In this presentation, we report our approaches to the ISO/IEC 17025 accreditation and operation status. (author)

Individual dosimetry and calibration

International Nuclear Information System (INIS)

Otto, T.

1997-01-01

In 1996, the Dosimetry and Calibration Section was, as in previous years, mainly engaged in routine tasks: the distribution of over 6000 dosimeters (with a total of more than 10,000 films) every two months and the calibration of about 900 fixed and mobile instruments used in the radiation survey sections of RP group. These tasks were, thanks to an experienced team, well mastered. Special efforts had to be made in a number of areas to modernize the service or to keep it in line with new prescriptions. The Individual Dosimetry Service had to assure that CERN's contracting firms comply with the prescriptions in the Radiation Safety Manual (1996) that had been inspired by the Swiss Ordinance of 1994: Companies must file for authorizations with the Swiss Federal Office for Public Health requiring that in every company an 'Expert in Radiation Protection' be nominated and subsequently trained. CERN's Individual Dosimetry Service is accredited by the Swiss Federal Authorities and works closely together with other, similar services on a rigorous quality assurance programme. Within this framework, CERN was mandated to organize this year the annual Swiss 'Intercomparison of Dosimeters'. All ten accredited dosimetry services - among others those of the Paul Scherrer Institute (PSI) in Villigen and of the four Swiss nuclear power stations - sent dosimeters to CERN, where they were irradiated in CERN's calibration facility with precise photon doses. After return to their origin they were processed and evaluated. The results were communicated to CERN and were compared with the originally given doses. A report on the results was subsequently prepared and submitted to the Swiss 'Group of Experts on Personal Dosimetry'. Reference monitors for photon and neutron radiation were brought to standard laboratories to assure the traceability of CERN's calibration service to the fundamental quantities. For photon radiation, a set of ionization chambers was calibrated in the reference field

In Switzerland, the legal use of open radioactive sources in nuclear medicine and the general requirements for quality controls are defined in a federal ordinance. The metrological traceability is guaranteed through a directive of the Swiss metrological office (M.E.T.A.S.) that requires each instrument to be monitored at least once a year through either a verification or an intercomparison. The verification is performed onsite by an accredited laboratory with a set of three gamma sources (Co-57, Cs-137 and Co-60) and - if applicable - a beta source (Sr-90/Y- 90). The intercomparison is made through conventional mail. A source of I-131 or Tc- 99 m is measured both in the nuclear medicine department and in an accredited laboratory. The maximum tolerated error is 10% for gamma sources and 20% for beta sources. This methodology guarantees that the instruments have a correct response for most of the energy range used in practice. Not all nuclides are systematically probed and manufacturers are ultimately responsible for the calibration factors. The precision of the measurements performed in Switzerland is satisfactory with only about 6% of the measurements out of the tolerances. This monitoring also allowed us to improve the skills of the personnel and update the park of instruments by getting rid of dose calibrators displaying old units. (authors)

High dose calibrations at the Pacific Northwest Laboratory

McDonald, J.C.; Fox, R.A.

1988-10-01

The need is increasing for both high radiation exposures and calibration measurements that provide traceability of such exposures to national standards. The applications of high exposures include: electronic component damage studies, sterilization of medical products and food irradiation. Accurate high exposure measurements are difficult to obtain and cannot, in general, be carried out with a single dose measurement system or technique because of the wide range of doses and the variety of materials involved. This paper describes the dosimetric measurement and calibration techniques used at the Pacific Northwest Laboratory (PNL) that make use of radiochromic dye films, thermoluminescent dosimeters (TLDs), ionization chambers, and calorimetric dosimeters. The methods used to demonstrate the consistency of PNL calibrations with national standards will also be discussed. 4 refs

The Mars Science Laboratory Curiosity rover carries a basalt calibration target for monitoring the performance of the alpha particle X-ray spectrometer. The spectrum acquired on Sol 34 shows increased contributions from Mg, S, Cl and Fe relative to laboratory spectra recorded before launch. Mars Hand Lens Imager images confirm changes in the appearance of the surface. Spectra taken on Sols 179 and 411 indicate some loss of the deposited material. The observations suggest deposition of a surface film likely consisting of dust mobilized by impingement of the sky crane’s terminal descent engine plumes with surface fines during Curiosity’s landing. New APXS software has been used to model the thin film that coated the calibration target on landing. The results suggest that a film of about 100 nm thickness, and containing predominantly MgO, Fe 2 O 3 , SO 3 , Cl and Na 2 O could give rise to the observed spectral changes. If this film is also present on the alpha particle sources within the APXS, then its effect is negligible and the terrestrial calibration remains appropriate

Standardization of the calibration of brachytherapy sources at the IAEA dosimetry laboratory

International Nuclear Information System (INIS)

Shanta, A.; Andreo, P.

1996-01-01

A new service to SSDLs has been initiated at the IAEA Dosimetry Laboratory for providing calibrations of well-type ionisation chambers, used in brachytherapy applications, which are traceable to the International Measurement System. Considering that the most common radionuclide used in the developing countries is 137 Cs, two such sources of the type used for gynaecological intracavitary applications have been purchased by the Agency and calibrated at the National Institute of Standards and Technology (NIST), USA. These 137 Cs reference sources together with a well-type ionization chamber constitute the IAEA brachytherapy dosimetry standard. Based on the recommendations by a group of experts, a method has been developed for transferring calibrations to SSDLs which is described in this paper. The method is based on the acquisition by the SSDLs of sources and equipment similar to those at the IAEA. The well-type chamber is to be calibrated at the IAEA Dosimetry Laboratory, and this will be used at the SSDL to calibrate its own reference sources. These sources can in turn by used to calibrate well-type chambers from hospital users and to calibrate other type of sources by performing measurements in air. In order to standardize the procedures for the two methods and to provide guidance to the SSDLs, measurements have been carried out at the IAEA Dosimetry Laboratory. The reproducibility of the two type of measurements has been found to be better than 0.5%, and the uncertainty of calibrations estimated to be less than 1.5% (one standard deviation).

Warshawsky, I.

1982-01-01

Calibrations by four U.S. laboratories of four hot-cathode ion gauges, in the range 0.07-13 mPa, showed systematic differences among laboratories that were much larger than the expected error of any one calibration. They also suggested that any of the four gauges tested, if properly packaged and shipped, was able to serve as a transfer standard with probable error of 2%. A second comparison was made of the calibrations by two U.S. laboratories of some other gauges that had also been calibrated by the National Physical Laboratory, England. Results did not permit conclusive determination of whether differences were due to the laboratories or to changes in the gauges.

A state-of-art TLD laboratory has been commissioned in January 2000 at Radiological Safety Division of Indira Gandhi Centre for Atomic Research (IGCAR). The laboratory provides personnel monitoring service to 2000 occupational workers from Indira Gandhi Centre for Atomic Research and Bhabha Atomic Research Centre facilities. The laboratory has been accredited by the Radiation Safety Systems Division (RSSD), Bhabha Atomic Research Centre (BARC) since year 2002. The laboratory has exclusive facility for the calibration of the TLD cards. As apart of accreditation procedure and taking into account of geometry effect, the dose rate at the card position is determined by the accreditation authorities by using graphite chamber (secondary or national standard instrument) and often re estimated by a condenser R meter (M/s Victoreen, Germany) by our laboratory. As per the regulatory requirement, the exposure protocols should be automated. Towards this an automatic source movement system has been augmented in the calibration facility. By using the system, the source will be brought to the irradiation position by pneumatically and exposures will be terminated by counter, timer and triggering system. To accomplish this task a lead container has been designed, fabricated and mounted at the beneath of the calibration table for the storage of source. As per the automation process, a lead container for the source storage has been designed and installed beneath to the Calibration Table. The container was designed to hold a 3Ci 137 Cs source, but present activity of the source is 1.2Ci. Hence, the shielding integrity was tested with higher active source (1.7Ci 60 Co). The dose rate measured outside on the circumference of the container at the middle of the source is found to be the same as calculated using QAD CGGP calculations. The top plug is so designed to avoid inadvertent upward movement of the source. Though, the shielding was not adequate on top of the top plug, however it does

One of the missions of the Laboratory of Biological Dosimetry (L.D.B.) of the Institute for Radiation and Nuclear Safety (I.R.S.N.) is to assess the radiological dose after an accidental overexposure suspicion to ionising radiation, by using radio-induced changes of some biological parameters. The 'gold standard' is the yield of dicentrics observed in patients lymphocytes, and this yield is converted in dose using dose effect relationships. This method is complementary to clinical and physical dosimetry, for medical team in charge of the patients. To obtain a formal recognition of its operational activity, the laboratory decided three years ago, to require an accreditation, by following the recommendations of both 17025 General Requirements for the Competence of Testing and Calibration Laboratories and 19238 Performance criteria for service laboratories performing biological dosimetry by cyto-genetics. Diagnostics, risks analysis were realized to control the whole analysis process leading to documents writing. Purchases, personnel department, vocational training were also included in the quality system. Audits were very helpful to improve the quality system. One specificity of this technique is that it is not normalized therefore apart from quality management aspects, several technical points needed some validations. An inventory of potentially influent factors was carried out. To estimate their real effect on the yield of dicentrics, a Placket-Burman experimental design was conducted. The effect of seven parameters was tested: the BUdr (bromodeoxyuridine), PHA (phytohemagglutinin) and colcemid concentration, the culture duration, the incubator temperature, the blood volume and the medium volume. The chosen values were calculated according to the uncertainties on the way they were measured i.e. pipettes, thermometers, test tubes.

The nuclear medicine techniques efficiency and safety depends on, beside other factors, a quality control programme, mainly regards to the nuclides activimeter utilization. The Calibration Laboratory of IPEN uses as a work standard, a tertiary standard system Capintec, calibrated at the Accredited Dosimetry Calibration Laboratory of the Medical radiation Research Center - University of Wisconsin. In this work, as preliminary measurements to establish a quality control programme for the activimeter calibration procedures, initially the repeatability and reproducibility (long term stability) tests were performed using a sealed check source of 133 Ba. Later on, to complete this quality control programme other check sources ( 137 Cs, 57 Co, 60 Co) will be used to perform the same tests. A series of 80 experiments of 10 measurements each has been carried out. The reference system showed a good behaviour to the repeatability test, considering the tolerance limits of 5%. The percent deviations of all tested sources in the activity measurements were lower 1% to 133 Ba. (author)

High Performance Liquid Chromatography LC-UV and LC-MS/MS methods were developed and validated for quantitative analyses of sodium benzoate and potassium sorbate in foods and beverages. HPLC-UV and LC-MS/MS methods were compared for quantitative analyses of sodium benzoate and potassium sorbate in a representative ketchup sample. Optimisation of the methods enabled the chromatographic separation of the analytes in less than 4 min. A correlation coefficient of 0.999 was achieved over the measured calibration range for both compounds and methods (HPLC and LC-MS/MS). The uncertainty values of sodium benzoate and potassium sorbate were found as 0.199 and 0.150 mg/L by HPLC and 0.072 and 0.044 mg/L by LC-MS/MS, respectively. Proficiency testing performance of Turkish accredited laboratories between the years 2005 and 2013 was evaluated and reported herein. The aim of the proficiency testing scheme was to evaluate the performance of the laboratories, analysing benzoate and sorbate in tomato ketchup. Copyright © 2014 Elsevier Ltd. All rights reserved.

Calibration for plutonium-238 lung counting at Mound Laboratory

International Nuclear Information System (INIS)

Tomlinson, F.K.

1976-01-01

The lung counting facility at Mound Laboratory was calibrated for making plutonium-238 lung deposition assessments in the fall of 1969. Phoswich detectors have been used since that time; however, the technique of calibration has improved considerably. The current technique of calibrating the lung counter is described as well as the method of error analysis and determination of the minimum detectable activity. A Remab hybrid phantom is used along with an attenuation curve which is derived from plutonium loaded lungs and ground beef absorber measurements. The errors that are included in an analysis as well as those that are excluded are described. The method of calculating the minimum detectable activity is also included

The Department of Energy Radiological Calibration Intercomparison Program was initiated in January 1986, under the research portion of the DOE Laboratory Accreditation Program. The program operates via the exchange of transfer standards, consisting of instrument sets and standard secondary beta sources. There are two instrument sets and the scheduled use has been staggered such that one set is available for use during each month. One set of secondary standard beta sources is available for use bimonthly. During the 1986 fiscal year, five laboratories used the instrument sets and three laboratories used the beta source set. Results were reported for all the measurements. The average and one standard deviation of the ratios of participant results to Pacific Northwest Laboratory calibration values were 1.12 +- 0.17 for gamma measurements. Those ratios for the gamma measurements varied from 0.98 to 3.06. The larger differences of results from measurements performed at two facilities were directly attributable to unfamiliarity with the intercomparison instruments. The average and one standard deviation of the ratios of participant results to PNL calibration values obtained using the secondary 90 Sr beta source was 1.02 +- 0.05, which is well within measurement uncertainties. The one participant who performed measurements using 147 Pm and 204 Tl sources obtained ratios of 0.68 and 1.11, respectively. No measurements were performed using neutron or x-ray sources

This work is part of a cooperation plan between the LNMRI/IRD and the LCR/UERJ, for the a primary calibration at the IRD and a secondary laboratory at the LCR, both calibrated for mammographic beams which will be part a Calibration National Network. For the mounting of the primary laboratory, the first step was to install two additional collimators in order to guarantee that the beam area over the ionization chamber to satisfy the calibration international standards. So, the collimators were constructed obeying the geometric rules, the first being of conic format and the second of the cylindrical format, therefore avoiding the effects of the scattering radiation on the edges. By using this collimation system it was possible to verify the uniformity of the radiation field incident the ionization chamber to be over 98% of the total area, guaranteeing better precision of the measurement

1999-07-01

The use of linear accelerators in radiotherapy is of great importance in Medicine, and according to international recommendations the electron beam dosimetry has to be performed using plane-parallel ionization chambers, previously calibrated in standard gamma radiation fields at accredited laboratories. In this work, calibration methods of plane-parallel ionization chambers used in dosimetry procedures of high energy electron beams of clinical accelerators were presented, tested and intercompared. The experiments were carried out using gamma radiation beams of {sup 60} Co at the Calibration Laboratory of Clinical Dosemeters at IPEN and electron beams od 4 to 16 MeV at the Radiotherapy Department of Hospital Israelita Albert Einstein, Sao Paulo. A method was chosen to be established at IPEN. Proposals of the calibration procedure, calibration certificate and data sheets are presented. (author)

In Brazil there are over 100 high dose rate (HDR) brachytherapy facilities using well-type chambers for the determination of the air kerma rate of {sup 192}Ir sources. This paper presents the methodology developed and extensively tested by the Laboratorio de Ciencias Radiologicas (LCR) and presently in use to calibrate those types of chambers. The system was initially used to calibrate six well-type chambers of brachytherapy services, and the maximum deviation of only 1.0% was observed between the calibration coefficients obtained and the ones in the calibration certificate provided by the UWADCL. In addition to its traceability to the Brazilian National Standards, the whole system was taken to University of Wisconsin Accredited Dosimetry Calibration Laboratory (UWADCL) for a direct comparison and the same formalism to calculate the air kerma was used. The comparison results between the two laboratories show an agreement of 0.9% for the calibration coefficients. Three Brazilian well-type chambers were calibrated at the UWADCL, and by LCR, in Brazil, using the developed system and a clinical HDR machine. The results of the calibration of three well chambers have shown an agreement better than 1.0%. Uncertainty analyses involving the measurements made both at the UWADCL and LCR laboratories are discussed.

Tritium monitor calibration at Los Alamos National Laboratory

International Nuclear Information System (INIS)

Bjork, C.J.; Aikin, D.J.; Houlton, T.W.

1997-08-01

Tritium in air is monitored at Los Alamos National Laboratory (LANL) with air breathing instruments based on ionization chambers. Stack emissions are continuously monitored from sample tubes which each connect to a Tritium bubble which differentially collects HTO and HT. A set of glass vials of glycol capture the HTO. The HT is oxidized with a palladium catalyst and the resultant HTO is captured in a second set of vials of glycol. The glycol is counted with a liquid scintillation counter. All calibrations are performed with tritium containing gas. The Radiation Instrumentation and Calibration (RIC) Team has constructed and maintains two closed loop gas handling systems based on femto TECH model U24 tritium ion chamber monitors: a fixed system housed in a fume hood and a portable system mounted on two two wheeled hand trucks. The U24 monitors are calibrated against tritium in nitrogen gas standards. They are used as standard transfer instruments to calibrate other ion chamber monitors with tritium in nitrogen, diluted with air. The gas handling systems include a circulation pump which permits a closed circulation loop to be established among the U24 monitor and typically two to four other monitors of a given model during calibration. Fixed and portable monitors can be calibrated. The stack bubblers are calibrated in the field by: blending a known concentration of tritium in air within the known volume of the two portable carts, coupled into a common loop; releasing that gas mixture into a ventilation intake to the stack; collecting oxidized tritium in the bubbler; counting the glycol; and using the stack and bubbler flow rates, computing the bubbler's efficiency. Gas calibration has become a convenient and quality tool in maintaining the tritium monitors at LANL

To investigate the state of the art of intra-laboratory turnaround time (intra-TAT), provide suggestions and find out whether laboratories accredited by International Organization for Standardization (ISO) 15189 or College of American Pathologists (CAP) will show better performance on intra-TAT than non-accredited ones. 479 Chinese clinical laboratories participating in the external quality assessment programs of chemistry, blood gas, and haematology tests organized by the National Centre for Clinical Laboratories in China were included in our study. General information and the median of intra-TAT of routine and stat tests in last one week were asked in the questionnaires. The response rate of clinical biochemistry, blood gas, and haematology testing were 36% (479/1307), 38% (228/598), and 36% (449/1250), respectively. More than 50% of laboratories indicated that they had set up intra-TAT median goals and almost 60% of laboratories declared they had monitored intra-TAT generally for every analyte they performed. Among all analytes we investigated, the intra-TAT of haematology analytes was shorter than biochemistry while the intra-TAT of blood gas analytes was the shortest. There were significant differences between median intra-TAT on different days of the week for routine tests. However, there were no significant differences in median intra-TAT reported by accredited laboratories and non-accredited laboratories. Many laboratories in China are aware of intra-TAT control and are making effort to reach the target. There is still space for improvement. Accredited laboratories have better status on intra-TAT monitoring and target setting than the non-accredited, but there are no significant differences in median intra-TAT reported by them.

Optimized star sensors laboratory calibration method using a regularization neural network.

Science.gov (United States)

High-precision ground calibration is essential to ensure the performance of star sensors. However, the complex distortion and multi-error coupling have brought great difficulties to traditional calibration methods, especially for large field of view (FOV) star sensors. Although increasing the complexity of models is an effective way to improve the calibration accuracy, it significantly increases the demand for calibration data. In order to achieve high-precision calibration of star sensors with large FOV, a novel laboratory calibration method based on a regularization neural network is proposed. A multi-layer structure neural network is designed to represent the mapping of the star vector and the corresponding star point coordinate directly. To ensure the generalization performance of the network, regularization strategies are incorporated into the net structure and the training algorithm. Simulation and experiment results demonstrate that the proposed method can achieve high precision with less calibration data and without any other priori information. Compared with traditional methods, the calibration error of the star sensor decreased by about 30%. The proposed method can satisfy the precision requirement for large FOV star sensors.

Conformity Assessment Bodies (laboratories , certification and inspection bodies, etc ) assess conformity of products and services to requirements , usually relating to quality and safety. For their activities to provide due confidence both in national and international markets these bodies must demonstrate to have the relevant technical competence and to perform according to international standards. This confidence is based on the assessments conducted in different countries by the accreditation body in Spain ENAC. Using accredited conformity assessment bodies bodies: risks are minimized; customer confidence is increased; acceptance in foreign countries is enhanced; self-regulation is promoted. (Author)

Background/Objectives: The specific credentials and continuing education (CME/CE) of nuclear cardiology laboratory medical and technical staff are important factors in the delivery of quality imaging services that have not been systematically evaluated. Methods: Nuclear cardiology accreditation application data from the Intersocietal Accreditation Commission (IAC) was used to characterize facilities performing myocardial perfusion imaging by setting, size, previous accreditation and credentials of the medical and technical staff. Credentials and CME/CE were compared against initial accreditation decisions (grant or delay) using multivariable logistic regression. Results: Complete data were available for 1913 nuclear cardiology laboratories from 2011-2014. Laboratories with initial positive accreditation decisions had a greater prevalence of Certification Board in Nuclear Cardiology (CBNC) certified medical directors and specialty credentialed technical directors. Certification and credentials of the medical and technical directors, respectively, staff CME/CE compliance, and assistance of a consultant with the application were positively associated with accreditation decisions. Conclusion: Nuclear cardiology laboratories directed by CBNC-certified physicians and NCT- or PET-credentialed technologists were less likely to receive delay decisions for MPI. CME/CE compliance of both the medical and technical directors was associated with accreditation decision. Medical and technical directors' years of experience were not associated with accreditation decision. Copyright © 2017 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

Applied tests were: repeatability, reproducibility and current leakage. Thus it was possible to determine the most common defects found in these equipment and the actions that could be taken to prevent it (clinical dosimeters quality control programs). The behaviour of 167 dosimeters was analyzed and in this study, 62 of them have been tested. The main problem detected during calibration tests was current leakage, i.e. electronic noise. The tests were applied to the routine measurements at the Calibration Laboratory implementing an ideal calibration procedure. New calibration criteria were established following international recommendations. Therefore, it was made the improvement of the quality control programme of the clinical dosimeters calibration laboratory, benefiting the users of such equipment with better consistent calibration measurements.

Standards for accreditation of laboratories as in ISO 9001 in section: 4.11 require inspection, measuring and equipment testing; likewise, IEC 17025: 2005 in section: 5.5.2 requires the equipment to be calibrated or verified before being put into use. In our laboratory, quality control is often accomplished by standards set done by the laboratory scientists themselves; however, at present, Hellma secondary calibration standards (4026 - Holmium oxide - Filters: F0, F2, F3, F4 and filter didymium - F7) have been used in order to verify if errors in the laboratory have been close to the 1-2% margin. Control graphs were made by using the results of synthetically prepared standards and standardized spectral calibration certificates. The set of secondary calibration standards permits to check the accuracy of the spectrophotometers used in research for both the absorbance in the visible spectrum (at 440, 465, 546, 590 and 635 nm wavelengths) and for the wavelengths (270, 280, 300, 320 nm) of the ultraviolet light. Filters (F0, F2, F3, F4 and F7) are stable and do not suffer the influence of temperature (the influence is negligible), the F0 filter was being used as a blank. The purpose is to verify whether the spectrometer needs adjustments, an important procedure to check absorbance stability, baseline flatness, slit width accuracy and stray radiation. The calibration tests are performed annually in our laboratory and recalibration of Hellma secondary standards is recommended every two years. The results show that the Chemical Dosimetry Laboratory in CRCN has a calibrated spectrophotometer and their synthetic standards for Fricke dosimetry could be used as an alternative method for testing the proficiency and competence of calibration laboratories in accordance with the regulations and standards.

The safety aspects of lighting are self-evident in areas such as road lighting, urban lighting and also indoor lighting. The use of photometers to measure lighting levels requires traceability obtained in accredited laboratories, which must provide an associated uncertainty. It is therefore relevant to study the impact of known uncertainty sources like the vertical angular deviation of photometer calibration benches, in order to define criteria to its quality assessment

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

Full Text Available According as the international definition of Flexible Scope, a laboratory must demonstrate face with the accreditation body that it has the knowledge, experience and competence to work within the full range of its flexible scope, as well as possessing suitable laboratory environments and equipment. The laboratory must also demonstrate that it has a management system in place that can control its proposed approach while continuing to comply with the requirements of ISO 17025:2005. In case of UKAS (Unites Kingdom Accreditation Service, prior to offering accreditation for flexible scope they must have a high degree of confidence that the staff are technically competent and that the management system controlling certain key processes as development, review, validation and authorization.LATU apply these requirements since 2004 as "Unified Tests".

This was a descriptive study using non-probabilistic sampling and the criterion of a greater equipment inventory and service demand for Clinics, Aesthetic, Radiology and Dentistry Centres and Hospitals. Census; the instrument was applied to 32 health-care institutions distributed throughout the Risaralda departments 14 municipalities between September 2005 and January 2006. Hospitals was the category having a highest number of electro-medical equipment (56%). Pereira (the capital of Risaralda) had 81% of all electro-medical equipment. All the institutions lacked NTC-ISO-IEC-17025 accreditation regarding standards certified by the Superintendence of Industry and Commerce. None of the institutions externally contracted by the institutions being surveyed was accredited. There is a public health risk in the Risaralda department; all health-care institutions lacked NTC-ISO-IEC-17025 accreditation and external institutions (in turn being hired by them for calibrating their equipment) also lacked accreditation. Based on the information obtained from non-calibrated equipment having international patterns, there is a great danger that determining the quality of biomedical equipment calibration patterns may be erroneous. It also places health-care institutions at a competitive disadvantage when compared to other accredited institutions in Colombia or in other countries.

Guidelines for establishing quality systems in veterinary diagnostic testing laboratories. Report of a Joint FAO/IAEA consultants meeting/workshop. Draft

International Nuclear Information System (INIS)

2002-01-01

The purpose of this report is to assist veterinary testing laboratories to develop and implement a quality system based on the OIE Standard 'Management and Technical Requirements for Laboratories Conducting Tests for Infectious Animal Diseases'. The introduction to the OIE Standard states: This document describes the OIE Standard for management and technical competence that serves as the basis for accreditation of laboratories that conduct tests for infectious animal diseases, especially those laboratories involved in testing for international trade. It contains the specific requirements unique to laboratories conducting tests for infectious animal diseases. These specific requirements represent an interpretation of the generally stated requirements of ISO/IEC 17025:1999, General requirements for the competence of testing and calibration laboratories (as outlined in Annex B of ISO/IEC 17025). Accreditation bodies that recognize the competence of such testing laboratories may use this Standard as the basis for their accreditation. This report gives an example-oriented overview of the structure and contents of critical documents and procedures such as Quality Manual (QM), Standard Operating Procedures (SOPs), etc. inherent to a quality system and describes the different stages in the implementation of the OIE Standard. For that reason it can be used as a practical guide for the production of necessary documents but also as a help to determine the status of a laboratory during its journey towards establishing a QS

Strengthening Laboratory Management Toward Accreditation (SLMTA) is a competency-based management training programme designed to bring about immediate and measurable laboratory improvement. The aim of this study is to assess the outcome of SLMTA on laboratory quality management system in Addis Ababa, Ethiopia. The study used an Institutional based cross sectional study design that employed a secondary and primary data collection approach on the participated institution of medical laboratory in SLMTA. The study was conducted in Addis Ababa city government and the data was collected from February 'April 2014 and data was entered in to EPI-data version 3.1 and was analyzed by SPSS version 20. The assessment finding indicate that there was a significant improvement in average scores (141.4; range of 65-196, 95%CI=86.275-115.5, p=0.000) at final with 3 laboratories become 3 star, 6 laboratories were at 2 star, 11 were 1 star. Laboratory facilities respondents which thought getting adequate and timely manner mentorship were found 2.5 times more likely to get good success in the final score(AOR=2.501, 95% CI=1.109-4.602) than which did not get it. At the end of SLMTA implementation,3 laboratories score 3 star, 6 laboratories were at 2 star, 11 were at 1 star. The most important contributing factor for not scoring star in the final outcome of SLMTA were not conducting their customer satisfaction survey, poor staff motivation, and lack of regular equipment service maintenance. Mentorship, onsite and offsite coaching and training activities had shown a great improvement on laboratory quality management system in most laboratories.

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

A recent survey of laboratories in Kampala, Uganda, demonstrated that only 0.3% of laboratories (3/954) met international quality standards. To benchmark laboratory quality throughout the rest of sub-Saharan Africa (SSA), we compiled a list of SSA laboratories meeting international quality standards. Accrediting bodies were queried via online registries or direct communication in May 2013. There were 380 laboratories accredited to international standards in SSA. Ninety-one percent were in South Africa. Thirty-seven of 49 countries had no laboratories accredited to international quality standards. Accredited laboratory density (per million people) in South Africa, Namibia, and Botswana were similar to those in many European countries. Single variable linear regression showed a correlation between accredited laboratory density and health expenditures per person (adjusted R(2) = 0.81, P clinical laboratory. For those that do, there is a strong correlation between country-specific accredited laboratory density and per-capita health expenditures. Copyright© by the American Society for Clinical Pathology.

2009-11-01

The designed hyperspectral imaging system is composed of three main parts, that is, optical subsystem, electronic subsystem and capturing subsystem. And a three-dimensional "image cube" can be obtained through push-broom. The fore-optics is commercial-off-the-shelf with high speed and three continuous zoom ratios. Since the dispersive imaging part is based on Offner relay configuration with an aberration-corrected convex grating, high power of light collection and variable view field are obtained. The holographic recording parameters of the convex grating are optimized, and the aberration of the Offner configuration dispersive system is balanced. The electronic system adopts module design, which can minimize size, mass, and power consumption. Frame transfer area-array CCD is chosen as the image sensor and the spectral line can be binned to achieve better SNR and sensitivity without any deterioration in spatial resolution. The capturing system based on the computer can set the capturing parameters, calibrate the spectrometer, process and display spectral imaging data. Laboratory calibrations are prerequisite for using precise spectral data. The spatial and spectral calibration minimize smile and keystone distortion caused by optical system, assembly and so on and fix positions of spatial and spectral line on the frame area-array CCD. Gases excitation lamp is used in smile calibration and the keystone calculation is carried out by different viewing field point source created by a series of narrow slit. The laboratory and field imaging results show that this pushbroom hyperspectral imaging system can acquire high quality spectral images.

Construction and operation of an improved radiation calibration facility at Brookhaven National Laboratory. Environmental assessment

International Nuclear Information System (INIS)

1994-10-01

Calibration of instruments used to detect and measure ionizing radiation has been conducted over the last 20 years at Brookhaven National Laboratory's (BNL) Radiation Calibration Facility, Building 348. Growth of research facilities, projects in progress, and more stringent Department of Energy (DOE) orders which involve exposure to nuclear radiation have placed substantial burdens on the existing radiation calibration facility. The facility currently does not meet the requirements of DOE Order 5480.4 or American National Standards Institute (ANSI) N323-1978, which establish calibration methods for portable radiation protection instruments used in the detection and measurement of levels of ionizing radiation fields or levels of radioactive surface contaminations. Failure to comply with this standard could mean instrumentation is not being calibrated to necessary levels of sensitivity. The Laboratory has also recently obtained a new neutron source and gamma beam irradiator which can not be made operational at existing facilities because of geometry and shielding inadequacies. These sources are needed to perform routine periodic calibrations of radiation detecting instruments used by scientific and technical personnel and to meet BNL's substantial increase in demand for radiation monitoring capabilities. To place these new sources into operation, it is proposed to construct an addition to the existing radiation calibration facility that would house all calibration sources and bring BNL calibration activities into compliance with DOE and ANSI standards. The purpose of this assessment is to identify potential significant environmental impacts associated with the construction and operation of an improved radiation calibration facility at BNL

Bangi, J. O.; Maranga, S. M.; Nganga, S. P.; Mutuli, S. M.

This paper describes the facilities, instrumentation and procedures currently used in the force laboratory at the Kenya Bureau of Standards (KEBS) for force measurement services. The laboratory uses the Force Calibration Machine (FCM) to calibrate force-measuring instruments. The FCM derives its traceability via comparisons using reference transfer force transducers calibrated by the Force Standard Machines (FSM) of a National Metrology Institute (NMI). The force laboratory is accredited to ISO/IEC 17025 by the Germany Accreditation Body (DAkkS). The accredited measurement scope of the laboratory is 1 MN to calibrate force transducers in both compression and tension modes. ISO 376 procedures are used while calibrating force transducers. The KEBS reference transfer standards have capacities of 10, 50, 300 and 1000 kN to cover the full range of the FCM. The uncertainty in the forces measured by the FCM were reviewed and determined in accordance to the new EURAMET calibration guide. The relative expanded uncertainty of force W realized by FCM was evaluated in a range from 10 kN-1 MN, and was found to be 5.0 × 10-4 with the coverage factor k being equal to 2. The overall normalized error (En) of the comparison results was also found to be less than 1. The accredited Calibration and Measurement Capability (CMC) of the KEBS force laboratory was based on the results of those intercomparisons. The FCM enables KEBS to provide traceability for the calibration of class ‘1’ force instruments as per the ISO 376.

The Calibration Laboratory of Instruments of Instituto de Pesquisas Energeticas e Nucleares offers calibration services of radiation detectors used in radioprotection, diagnostic radiology and radiotherapy, for IPEN and for external facilities (public and private). One part of its facilities is located in the main building, along with other laboratories and study rooms, and another part in an isolated building called Bunker. For the optimization, modernization and specially the safety, the laboratories in the main building shall be transferred to an isolated place. In this work, a project of an integrated laboratory for calibration of instruments was developed, and it will be an expansion of the current Calibration Laboratory of Instruments of IPEN. Therefore, a series of radiometric monitoring of the chosen localization of the future laboratory was realized, and all staff needs (dimensions and disposition of the study rooms and laboratories) were defined. In this project, the laboratories with X ray equipment, alpha and beta radiation sources were located at an isolated part of the building, and the wall shielding was determined, depending on the use of each laboratory.

European Commission Regulation 882/2004/EC requires that official control laboratories for foodstuffs in the member states are certified according to UNI EN ISO/IEC 17025:2005 (general requirement for the competence of calibration and testing laboratories). This mandatory requirement has resulted in a continuous adaptation and development of analytical procedures. The aim of this study was to develop a method for semiquantitative screening of polychlorinated biphenyls in fish for human consumption. According to the Commission Decision 657/2002/CE, the detection capability, the precision, the selectivity-specificity, and applicability-ruggedness-stability were determined to validate the method. Moreover, trueness was verified. This procedure resulted in rapid execution, which allowed immediate and effective intervention by the local health authorities to protect the health of consumers. Finally, the procedure has been recognized by the Italian accrediting body, ACCREDIA.

Training and accreditation for radon professionals in Sweden

International Nuclear Information System (INIS)

Mjoenes, L.; Soederman, A.-L.

2004-01-01

Radon training courses and seminars on radon have been arranged in Sweden since the early 1980s. A commercial educational company initiated the first regular training courses in 1987. Up to 1990 about 400 persons had attended courses in radon measurement and radon mitigation methods. In 1991 the training programme was taken over by the Swedish Radiation Protection Authority, SSI. Today SSI's Radon Training Programme comprises three different two-day courses, a Basic Radon Course and two continuation courses: Radon Measurements and Radon in Water. Until 2003 SSI also arranged courses about Radon Remedial Measures and Radon Investigation and Risk Map Production. The courses are arranged twice a year. Altogether, about 750 municipal environmental health officers and technicians from private companies have been educated in the SSI training programme between 1991 and 2003. The continuation courses are completed with an examination, consisting of a theoretical test. The names of the persons who pass are being published in a list that is found on the SSI web site. Since no certification system is currently in place for radon professionals in Sweden, this list helps people who need to get in contact with radon counsellors to find one in their area and is used by authorities as well as private house-owners. Since 1991 it has been possible to obtain accreditation for measurements of indoor radon in Sweden and since 1997, also for measurements of radon in water. Although accreditation is voluntary in Sweden, accredited laboratories perform most measurements, both for indoor air and water. Passing the examination in the SSI training courses is a condition for accreditation. The Swedish Board for Accreditation and Conformity Assessment, SWEDAC, is in charge of the accreditation. So far, three major companies have obtained accreditation for measurement of indoor radon and four have been accredited for measurements of radon in water

At the Centre d'etudes nucleaires, Grenoble, the Radiation Measurement Laboratory, which forms part of the Environmental Protection and Research Department, serves the entire Centre for purposes of dosimetry and the calibration of dose meters. The needs of radiation protection are such that one must have facilities for checking periodically the calibration of radiation-monitoring instruments and developing special dosimetry techniques. It was thought a good idea to arrange for the dosimetry and radiation protection team to assist other groups working at the Centre - in particular, the staff of the biology and radiobiology laboratories - and also bodies outside the framework of the French Commissariat a l'energie atomique. Thus, technical collaboration has been established with, for example, Grenoble's Centre hospitalier universitaire (university clinic), which makes use of the facilities and skills available at the Radiation Measurement Laboratory for solving special dosimetry problems. With the Laboratory's facilities it is possible to calibrate dose meters for gamma, beta and neutron measurements

2017-08-01

This paper shows a statistical analysis on experimental calibration data for flowmeters (i.e.: electromagnetic, ultrasonic, turbine flowmeters) in pressure pipes. The experimental calibration data set consists of the whole archive of the calibration tests carried out on 246 flowmeters from January 2001 to October 2015 at Settore Portate of Laboratorio di Idraulica “G. Fantoli” of Politecnico di Milano, that is accredited as LAT 104 for a flow range between 3 l/s and 80 l/s, with a certified Calibration and Measurement Capability (CMC) - formerly known as Best Measurement Capability (BMC) - equal to 0.2%. The data set is split into three subsets, respectively consisting in: 94 electromagnetic, 83 ultrasonic and 69 turbine flowmeters; each subset is analysed separately from the others, but then a final comparison is carried out. In particular, the main focus of the statistical analysis is the correction C, that is the difference between the flow rate Q measured by the calibration facility (through the accredited procedures and the certified reference specimen) minus the flow rate QM contemporarily recorded by the flowmeter under calibration, expressed as a percentage of the same QM .

A new calibration laboratory has been developed at the INP, Cracow, Poland. The laboratory is located in a hall of dimension 9 m (length) x 4 m (wide) x 4.5 m (height). For calibration purposes the Cs-137 source of activity 185 MBq / 5 Ci / is applied, placed in the 16 cm thick lead capsule. The beam is collimated using a collimator with a constant opening of 20 o . The source is placed 2 m above the ground to avoid albedo scattering. This source covers a dose rate range from 17 mGy/h to 290 μGy/h. For low-dose calibration 0.05 Ci source is applied. The positioning of the source and opening of the collimator is pneumatically controlled. The dosimeters to be calibrated are placed onto a vehicle with DC motor positioned by PC computer. The vehicle is remotely positioned with the precision of one millimetre at the distance from the source between 1 and 7 meters. The vehicle positioning is controlled electronically and additionally checked via TV-camera. Exact dosimeter positioning is performed with a medical cross-laser and with a telescope device. The construction of the vehicle allows for performing of angular irradiations. On the axis of the vehicle 320 keV Phillips X-ray tube is installed which may be used as an irradiation source. UNIDOS dosimeter with PTW ionisation chambers is used for determination of the dose rate. This calibration stand is designed for calibration of personal dosimeters, calibration of active devices for radiation protections and for research on the newly developed thermoluminescent materials.

QUALITY MANAGEMENT SYSTEM IN CLINICAL LABORATORIES ACCORDING TO THE ISO 15189:2007 STANDARD - EVALUATION OF THE BENEFITS OF IMPLEMENTATION IN AN ASSISTED REPRODUCTION LABORATORY

Directory of Open Access Journals (Sweden)

A.D. Sialakouma

2011-03-01

Full Text Available Biomedical science is a sensitive discipline and presents unique challenges due to its social character, continuous development and competitiveness. The issue of quality management systems and accreditation is gaining increasing interest in this sector. All over Europe, Health Services Units have started to introduce quality management systems and harmonization of criteria for accreditation is of increasing importance. Moreover, clinical laboratories, like the Assisted Reproduction laboratories and biochemical laboratories are required to apply a Quality Management System in order to ensure their correct, scientific and effective operation. Ultimately, it is a moral obligation for every health care organisation to supply the best possible care for the patient. The specific features and the diversity of clinical laboratories led to the introduction (2003 and, recently to the revision (2007 of the international standard ISO 15189, which is the first international standard developed specifically to address the requirements for accreditation of this type of laboratory. The basic principles for the quality assurance in the clinical laboratories are: x Complete and unambiguous standardized operating procedures. x Complete and unambiguous directives of operation. x Obligatory detailed written documentation, i.e., how each action is done, who will do it, where will this action take place and when. x Suitable scheduling of calibration/control/preventive maintenance of laboratory equipment and recording of each activity. x Distribution of responsibilities among the staff and continuous education and briefing according to current scientific data. x Complete and informed record file keeping. x Continuous improvement which is monitored with the adoption of quantified indicators. x Internal and external audit of all activities. x Troubleshooting. All these principles should be supported by the Management in order that the necessary adaptations should be made

Training Accreditation Program

International Nuclear Information System (INIS)

1989-01-01

The Training Accreditation Program establishes the objectives and criteria against which DOE nuclear facility training is evaluated to determine its readiness for accreditation. Training programs are evaluated against the accreditation objectives and criteria by facility personnel during the initial self-evaluation process. From this self-evaluation, action plans are made by the contractor to address the scope of work necessary in order to upgrade any deficiencies noted. This scope of work must be formally documented in the Training Program Accreditation Plan. When reviewed and approved by the responsible Head of the Field Organization and cognizant Program Secretarial Office, EH-1 concurrence is obtained. This plan then becomes the document which guides accreditation efforts for the contractor

The international evaluation of the Centre for Metrology and Accreditation (MIKES) is part of the process in which all relevant industrial and technology policy measures and organizations under the auspices of the Ministry of Trade and Industry (MTI) are being evaluated with the aim of improving their effectiveness. The overall conclusion of the evaluation is that MIKES is serving the country well. An effective national measurement system (FINMET) is being maintained which provides a wide range of calibration services covering most of the nation`s needs. The accreditation service (FINAS) is now well established, is operating effectively, and has good prospects for growth. The evaluators present, however, a number of proposals (including 33 specific recommendations) where they feel that the metrology and accreditation arrangements could be better-suited to meet future national and international challenges. According to the recommendations the Finnish quality policy framework should be developed in a consistent way. There is a need of a comprehensive governmental quality policy statement upon which the inter-ministry coordination and harmonization of various conformity assessment activities can be based. MIKES should retain its current status as an agency within MTI. The national measurement system should be more centralised and a new purpose-built national standards laboratory should be procured. The responsibility for legal metrology should be transferred to MIKES. The terms of reference and membership of Advisory Committee for Metrology, as well as the Advisory Committee for Accreditation should be revised to ensure wider representation of all relevant, and especially industrial interests

The increase in disease burden has continued to weigh upon health systems in Africa. The role of the laboratory has become increasingly critical in the improvement of health for diagnosis, management and treatment of diseases. In response, the World Health Organization Regional Office for Africa (WHO AFRO) and its partners created the WHO AFRO Stepwise Laboratory (Quality) Improvement Process Towards Accreditation (SLIPTA) program. WHO AFRO defined a governance structure with roles and responsibilities for six main stakeholders. Laboratories were evaluated by auditors trained and certified by the African Society for Laboratory Medicine. Laboratory performance was measured using the WHO AFRO SLIPTA scoring checklist and recognition certificates rated with 1-5 stars were issued. By March 2015, 27 of the 47 (57%) WHO AFRO member states had appointed a SLIPTA focal point and 14 Ministers of Health had endorsed SLIPTA as the desired programme for continuous quality improvement. Ninety-eight auditors from 17 African countries, competent in the Portuguese (3), French (12) and English (83) languages, were trained and certified. The mean score for the 159 laboratories audited between May 2013 and March 2015 was 69% (median 70%; SD 11.5; interquartile range 62-77). Of these audited laboratories, 70% achieved 55% compliance or higher (2 or more stars) and 1% scored at least 95% (5 stars). The lowest scoring sections of the WHO AFRO SLIPTA checklist were sections 6 (Internal Audit) and 10 (Corrective Action), which both had mean scores below 50%. The WHO AFRO SLIPTA is a process that countries with limited resources can adopt for effective implementation of quality management systems. Political commitment, ownership and investment in continuous quality improvement are integral components of the process.

[Future roles of clinical laboratories and clinical laboratory technologists in university hospitals].

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

Laboratories working towards accreditation by the International Standards Organization (ISO) 15189 standard are required to demonstrate the validity of their analytical methods. The different guidelines set by various accreditation organizations make it difficult to provide objective evidence that an in-house method is fit for the intended purpose. Besides, the required performance characteristics tests and acceptance criteria are not always detailed. The laboratory must choose the most suitable validation protocol and set the acceptance criteria. Therefore, we propose a validation protocol to evaluate the performance of an in-house method. As an example, we validated the process for the detection and quantification of lead in whole blood by electrothermal absorption spectrometry. The fundamental parameters tested were, selectivity, calibration model, precision, accuracy (and uncertainty of measurement), contamination, stability of the sample, reference interval, and analytical interference. We have developed a protocol that has been applied successfully to quantify lead in whole blood by electrothermal atomic absorption spectrometry (ETAAS). In particular, our method is selective, linear, accurate, and precise, making it suitable for use in routine diagnostics.

In the 2000s, a number of initiatives were taken internationally to improve quality in genetic testing services. To contribute to and update the limited literature available related to this topic, we surveyed 910 human molecular genetic testing laboratories, of which 291 (32%) from 29 European countries responded. The majority of laboratories were in the public sector (81%), affiliated with a university hospital (60%). Only a minority of laboratories was accredited (23%), and 26% was certified. A total of 22% of laboratories did not participate in external quality assessment (EQA) and 28% did not use reference materials (RMs). The main motivations given for accreditation were to improve laboratory profile (85%) and national recognition (84%). Nearly all respondents (95%) would prefer working in an accredited laboratory. In accredited laboratories, participation in EQA (Pquality assurance (Pquality implementation score (QIS), we showed that accredited laboratories (average score 92) comply better than certified laboratories (average score 69, Pquality indicators. We conclude that quality practices vary widely in European genetic testing laboratories. This leads to a potentially dangerous situation in which the quality of genetic testing is not consistently assured. PMID:22739339

Ultrasound data for laboratory calibration of an analytical model to calculate crack depth on asphalt pavements

Miguel A. Franesqui

2017-08-01

Full Text Available This article outlines the ultrasound data employed to calibrate in the laboratory an analytical model that permits the calculation of the depth of partial-depth surface-initiated cracks on bituminous pavements using this non-destructive technique. This initial calibration is required so that the model provides sufficient precision during practical application. The ultrasonic pulse transit times were measured on beam samples of different asphalt mixtures (semi-dense asphalt concrete AC-S; asphalt concrete for very thin layers BBTM; and porous asphalt PA. The cracks on the laboratory samples were simulated by means of notches of variable depths. With the data of ultrasound transmission time ratios, curve-fittings were carried out on the analytical model, thus determining the regression parameters and their statistical dispersion. The calibrated models obtained from laboratory datasets were subsequently applied to auscultate the evolution of the crack depth after microwaves exposure in the research article entitled “Top-down cracking self-healing of asphalt pavements with steel filler from industrial waste applying microwaves” (Franesqui et al., 2017 [1].

Laboratory calibrations of airborne gamma-ray spectrometers. Measurements and discussions of important parameters

International Nuclear Information System (INIS)

Korsbech, U.

1994-02-01

This report is the fourth of reports from The Department of Electrophysics covering measurement and interpretation of airborne gamma-spectrometry measurements. It describes different topics concerning the construction of a suitable calibration setup in the laboratory. The goal is to build a simple and cheap laboratory setup that can produce most of the gamma-ray data needed for an interpretation of spectra measured 50 to 120 m above ground level. A simple calibration setup has been build and tested. It may produce gamma-ray spectra similar to those measured in the air - from surface contamination with artificial nuclides and from 'bulk' natural radioactivity. It is possible to investigate the influence of the air above an aircraft carrying the detector (skyshine: scattering of gamma photons in the air above the detector). In order to reduce the influence of non-detected pile-up the count rates are kept low without reaching levels where the background spectra (to be subtracted) would cause unacceptable counting statistical fluctuations. Sources selected for the calibrations are heavy minerals sand (with thorium and uranium), potassium nitrate (with 40 K). These sources are 'bulk sources' of natural radioactivity. Cesium-137 has been selected as the basic artifical surface contamination nuclide. The report also discusses methods for comparing two spectra a priori assumed equal. Finally the properties of some materials that could be used as 'air-substitutes' in the calibration setup have been tested with respect to stability against moisture sorption. (au)

The National Radiation Laboratory (NRL), serving under the Ministry of Health, provides radiation protection services to the whole of New Zealand. Consequently it performs many functions that are otherwise spread amongst several organizations in larger countries. It is the national regulatory body for radiation protection. It writes and enforces codes of safe practice, and conducts safety inspections of all workplaces using radiation. It provides a personal monitoring service for radiation workers. It also maintains the national primary standards for x-ray exposure and 60 Co air kerma. These standards are transferred to hospitals through a calibration service. The purpose of this report is to outline the primary standards facilities at NRL, and to discuss the calibration of dosemeters using these facilities. (J.P.N.)

Full text: The Nuclear Energy Peruvian Institute (IPEN) has laboratories which offer services of radiological control. Radiometric analysis in raw and processed foodstuff is requested by several enterprises of both public and private sectors which uses the results for trading purposes like exportation, importation and licitations. The service of assays and calibration with reliable results has become a need due to the external audits performed by accredited laboratories to fulfil the requirements of the Peruvian standard organism. With the support of the International Atomic Energy Agency (IAEA), the IPEN laboratory of radiometric analysis implemented its quality system in 2001 under the ISO IEC 17025 Standard 'General Requirements for the Competence of the Calibration and Testing Laboratories' with the purpose to organize the activities and offer an enhanced service to the clients. The implementation of the quality system has allowed giving a better service with enhanced efficiency to the clients, assuring the reliability of the final output, the analytical results. It had been possible since the laboratories have participated in worldwide proficiency tests sponsored by the IAEA and currently work with reference material. The quality system allows identifying potential faults in any stage of the process in order to prevent any problem in the final output, assuring the appropriate quality of the issued analytical results and to take the necessary corrective actions to avoid those events to happen again. This study has identified and assessed several difficulties and troubles which prevent to fulfil the requirements of the Quality Standard and as a consequence, disable the sustainability of the quality systems and prevent the accreditation. Several proposals and solution alternatives which involve the Executive Staff and the proactive participation of the personnel are presented. (author)

Dynamic size spectrometry of airborne microorganisms: Laboratory evaluation and calibration

Science.gov (United States)

Qian, Yinge; Willeke, Klaus; Ulevicius, Vidmantas; Grinshpun, Sergey A.; Donnelly, Jean

Bioaerosol samplers need to be calibrated for the microorganisms of interest. The Aerosizer, a relatively new aerodynamic size spectrometer, is shown to be a suitable dynamic instrument for the evaluation and calibration of such samplers in the laboratory, prior to their use in the field. It provides the necessary reference count against which the microbiological response of the sampler can be compared. It measures the health-significant aerodynamic diameters of microorganisms down to 0.5 μm, thus including most of the bacteria, fungi and pollen found in outdoor and indoor air environments. Comparison tests with a laser size spectrometer indicate that the suspension of microorganisms needs to be washed several times before aerosolization to avoid coating of the airborne microorganisms with nutrients and microbial slime from the suspension, and to reduce the residue particles to sizes below the lowest size of the aerosolized microorganisms.

Allen, W. A.; Richardson, A. J.

1971-01-01

Stacked glass plates have been used to calibrate a laboratory spectrophotometer, over the spectral range 0.5-2.5 microns, for specular light. The uncalibrated instrument was characterized by systematic errors when used to measure the reflectance and transmittance of stacked glass plates. Calibration included first, a determination of the reflectance of a standard composed of barium sulfate paint deposited on an aluminum plate; second, the approximation of the reflectance and transmittance residuals between observed and computed values by means of cubic equations; and, finally, the removal of the systematic errors by a computer. The instrument, after calibration, was accurate to 1% when used to measure the reflectance and transmittance of stacked glass plates.

to analyze the cost of a self-owned network maintained by a Brazilian health insurance provider as compared to the price charged by accredited service providers, so as to identify whether or not the self-owned network is economically advantageous. for this exploratory study, the company's management reports were reviewed. The cost associated with the self-owned network was calculated based on medical and dental office visits and diagnostic/laboratory tests performed at one of the company's most representative facilities. The costs associated with third parties were derived from price tables used by the accredited network for the same services analyzed in the self-owned network. The full-cost method was used for cost quantification. Costs are presented as absolute values (in R$) and percent comparisons between self-owned network costs versus accredited network costs. overall, the self-owned network was advantageous for medical and dental consultations as well as diagnostic and laboratory tests. Pediatric and labor medicine consultations and x-rays were less costly in the accredited network. the choice of verticalization has economic advantages for the health care insurance operator in comparison with services provided by third parties.

Electronic laboratory quality assurance program: A method of enhancing the prosthodontic curriculum and addressing accreditation standards.

Moghadam, Marjan; Jahangiri, Leila

2015-08-01

An electronic quality assurance (eQA) program was developed to replace a paper-based system and to address standards introduced by the Commission on Dental Accreditation (CODA) and to improve educational outcomes. This eQA program provides feedback to predoctoral dental students on prosthodontic laboratory steps at New York University College of Dentistry. The purpose of this study was to compare the eQA program of performing laboratory quality assurance with the former paper-based format. Fourth-year predoctoral dental students (n=334) who experienced both the paper-based and the electronic version of the quality assurance program were surveyed about their experiences. Additionally, data extracted from the eQA program were analyzed to identify areas of weakness in the curriculum. The study findings revealed that 73.8% of the students preferred the eQA program to the paper-based version. The average number of treatments that did not pass quality assurance standards was 119.5 per month. This indicated a 6.34% laboratory failure rate. Further analysis of these data revealed that 62.1% of the errors were related to fixed prosthodontic treatment, 27.9% to partial removable dental prostheses, and 10% to complete removable dental prostheses in the first 18 months of program implementation. The eQA program was favored by dental students who have experienced both electronic and paper-based versions of the system. Error type analysis can yield the ability to create customized faculty standardization sessions and refine the didactic and clinical teaching of the predoctoral students. This program was also able to link patient care activity with the student's laboratory activities, thus addressing the latest requirements of the CODA regarding the competence of graduates in evaluating laboratory work related to their patient care.

Is gerontology ready for accreditation?

Science.gov (United States)

Haley, William E; Ferraro, Kenneth F; Montgomery, Rhonda J V

2012-01-01

The authors review widely accepted criteria for program accreditation and compare gerontology with well-established accredited fields including clinical psychology and social work. At present gerontology lacks many necessary elements for credible professional accreditation, including defined scope of practice, applied curriculum, faculty with applied professional credentials, and resources necessary to support professional credentialing review. Accreditation with weak requirements will be dismissed as "vanity" accreditation, and strict requirements will be impossible for many resource-poor programs to achieve, putting unaccredited programs at increased risk for elimination. Accreditation may be appropriate in the future, but it should be limited to professional or applied gerontology, perhaps for programs conferring bachelor's or master's degrees. Options other than accreditation to enhance professional skills and employability of gerontology graduates are discussed.

In 2012, the Vietnam Ministry of Health sought to improve the quality of health laboratories by introducing international quality standards. Strengthening Laboratory Management Toward Accreditation (SLMTA), a year-long, structured, quality improvement curriculum (including projects and mentorship) was piloted in 12 laboratories. Progress was measured using a standardized audit tool (Stepwise Laboratory Quality Improvement Process Towards Accreditation). All 12 pilot laboratories (a mix of hospital and public health) demonstrated improvement; median scores rose from 44% to 78% compliance. The public health laboratory in Hai Duong Province entered the program with the lowest score of the group (28%) yet concluded with the highest score (86%). Five months after the completion of the program, without any additional external support, they were accredited. Laboratory management/staff describe factors key to their success: support from the facility senior management, how-to guidance provided by SLMTA, support from the site mentor, and strong commitment of laboratory staff. Hai Duong preventive medical center is one of only a handful of laboratories to reach accreditation after participation in SLMTA and the only laboratory to do so without additional support. Due to the success seen in Hai Duong and other pilot laboratories, Vietnam has expanded the use of SLMTA. American Society for Clinical Pathology, 2017.

2010-04-01

Full Text Available Abstract Background One way to improve quality and safety in healthcare organizations (HCOs is through accreditation. Accreditation is a rigorous external evaluation process that comprises self-assessment against a given set of standards, an on-site survey followed by a report with or without recommendations, and the award or refusal of accreditation status. This study evaluates how the accreditation process helps introduce organizational changes that enhance the quality and safety of care. Methods We used an embedded multiple case study design to explore organizational characteristics and identify changes linked to the accreditation process. We employed a theoretical framework to analyze various elements and for each case, we interviewed top managers, conducted focus groups with staff directly involved in the accreditation process, and analyzed self-assessment reports, accreditation reports and other case-related documents. Results The context in which accreditation took place, including the organizational context, influenced the type of change dynamics that occurred in HCOs. Furthermore, while accreditation itself was not necessarily the element that initiated change, the accreditation process was a highly effective tool for (i accelerating integration and stimulating a spirit of cooperation in newly merged HCOs; (ii helping to introduce continuous quality improvement programs to newly accredited or not-yet-accredited organizations; (iii creating new leadership for quality improvement initiatives; (iv increasing social capital by giving staff the opportunity to develop relationships; and (v fostering links between HCOs and other stakeholders. The study also found that HCOs' motivation to introduce accreditation-related changes dwindled over time. Conclusions We conclude that the accreditation process is an effective leitmotiv for the introduction of change but is nonetheless subject to a learning cycle and a learning curve.

Health departments have various unique needs that must be addressed in preparing for national accreditation. These needs require time and resources, shortages that many health departments face. The Accreditation Support Initiative's goal was to test the assumption that even small amounts of dedicated funding can help health departments make important progress in their readiness to apply for and achieve accreditation. Participating sites' scopes of work were unique to the needs of each site and based on the proposed activities outlined in their applications. Deliverables and various sources of data were collected from sites throughout the project period (December 2011-May 2012). Awardees included 1 tribal and 12 local health departments, as well as 5 organizations supporting the readiness of local and tribal health departments. Sites dedicated their funding toward staff time, accreditation fees, completion of documentation, and other accreditation readiness needs and produced a number of deliverables and example documents. All sites indicated that they made accreditation readiness gains that would not have occurred without this funding. Preliminary evaluation data from the first year of the Accreditation Support Initiative indicate that flexible funding arrangements may be an effective way to increase health departments' accreditation readiness.

Strengthening organizational performance through accreditation research-a framework for twelve interrelated studies: the ACCREDIT project study protocol

Full Text Available Abstract Background Service accreditation is a structured process of recognising and promoting performance and adherence to standards. Typically, accreditation agencies either receive standards from an authorized body or develop new and upgrade existing standards through research and expert views. They then apply standards, criteria and performance indicators, testing their effects, and monitoring compliance with them. The accreditation process has been widely adopted. The international investments in accreditation are considerable. However, reliable evidence of its efficiency or effectiveness in achieving organizational improvements is sparse and the value of accreditation in cost-benefit terms has yet to be demonstrated. Although some evidence suggests that accreditation promotes the improvement and standardization of care, there have been calls to strengthen its research base. In response, the ACCREDIT (Accreditation Collaborative for the Conduct of Research, Evaluation and Designated Investigations through Teamwork project has been established to evaluate the effectiveness of Australian accreditation in achieving its goals. ACCREDIT is a partnership of key researchers, policymakers and agencies. Findings We present the framework for our studies in accreditation. Four specific aims of the ACCREDIT project, which will direct our findings, are to: (i evaluate current accreditation processes; (ii analyse the costs and benefits of accreditation; (iii improve future accreditation via evidence; and (iv develop and apply new standards of consumer involvement in accreditation. These will be addressed through 12 interrelated studies designed to examine specific issues identified as a high priority. Novel techniques, a mix of qualitative and quantitative methods, and randomized designs relevant for health-care research have been developed. These methods allow us to circumvent the fragmented and incommensurate findings that can be generated in small

Service accreditation is a structured process of recognising and promoting performance and adherence to standards. Typically, accreditation agencies either receive standards from an authorized body or develop new and upgrade existing standards through research and expert views. They then apply standards, criteria and performance indicators, testing their effects, and monitoring compliance with them. The accreditation process has been widely adopted. The international investments in accreditation are considerable. However, reliable evidence of its efficiency or effectiveness in achieving organizational improvements is sparse and the value of accreditation in cost-benefit terms has yet to be demonstrated. Although some evidence suggests that accreditation promotes the improvement and standardization of care, there have been calls to strengthen its research base.In response, the ACCREDIT (Accreditation Collaborative for the Conduct of Research, Evaluation and Designated Investigations through Teamwork) project has been established to evaluate the effectiveness of Australian accreditation in achieving its goals. ACCREDIT is a partnership of key researchers, policymakers and agencies. We present the framework for our studies in accreditation. Four specific aims of the ACCREDIT project, which will direct our findings, are to: (i) evaluate current accreditation processes; (ii) analyse the costs and benefits of accreditation; (iii) improve future accreditation via evidence; and (iv) develop and apply new standards of consumer involvement in accreditation. These will be addressed through 12 interrelated studies designed to examine specific issues identified as a high priority. Novel techniques, a mix of qualitative and quantitative methods, and randomized designs relevant for health-care research have been developed. These methods allow us to circumvent the fragmented and incommensurate findings that can be generated in small-scale, project-based studies. The overall

Soderman, A. L.

2003-01-01

Radon training courses and seminars of different kinds have been arranged in Sweden since the early 1980s. A commercial educational company initiated the first regular training courses in 1987. Up to 1990 about 400 persons had attended courses in radon measurement and radon mitigation methods. In 1991 the first in a series of courses focussed on radon from the ground and production of radon risk maps organised. From 1991 it has been possible to obtain accreditation for measurements of indoor radon in Sweden and from 1997 also for measurements of radon in water. Even if accreditation s is voluntary, in Sweden accredited laboratories perform most measurements, both for indoor air and water. A condition for accreditation in to have passed the examination following the training courses at SSI, SO far, three major companies have obtained accreditation for measurement of indoor radon and four have been accredited for measurements of radon in water. Education on radon is also given at universities and institutes of technology. A two-day course is included in the education for environmental health officers. A number of training courses aimed at real state agents have been organised by SSI through the years. During the autumn of 2001 altogether 400 authorised real estate agents attended a series of regional half-day courses. In 1995 SSI arranged an international training course, Radon Indoor Risk and Remedial Actions, in Stockholm for the European commission. About 40 scientists from all over Europe attended the course, which much appreciated by the participants. Today SSI's Radon Training Programme comprises five different courses, a Basic radon Course and four continuation courses: Radon measurements, Radon remedial measures, Radon in water and Radon investigation and risk map production. The courses are arranged twice a year, in spring and autumn, except the Radon risk map production course, which is arranged about every second year. Altogether, between 1991 and 2003

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

The purpose of this paper is to describe and understand the effects of the accreditation process on organizational control and quality management practices in two Quebec primary-care health organizations. A multiple-case longitudinal study was conducted taking a mixed qualitative/quantitative approach. An analytical model was developed of the effects of the accreditation process on the type of organizational control exercised and the quality management practices implemented. The data were collected through group interviews, semi-directed interviews of key informers, non-participant observations, a review of the literature, and structured questionnaires distributed to all the employees working in both institutions. The accreditation process has fostered the implementation of consultation mechanisms in self-assessment teams. Improving assessments of client satisfaction was identified as a prime objective but, in terms of the values promoted in organizations, accreditation has little effect on the perceptions of employees not directly involved in the process. As long as not all staff members have integrated the basis for accreditation and its outcomes, the accreditation process appears to remain an external, bureaucratic control instrument. This study provides a theoretical model for understanding organizational changes brought about by accreditation of primary services. Through self-assessment of professional values and standards, accreditation may foster better quality management practices.

Calibration

1981-01-01

Procedures common to different methods of calibration of neutron moisture meters are outlined and laboratory and field calibration methods compared. Gross errors which arise from faulty calibration techniques are described. The count rate can be affected by the dry bulk density of the soil, the volumetric content of constitutional hydrogen and other chemical components of the soil and soil solution. Calibration is further complicated by the fact that the neutron meter responds more strongly to the soil properties close to the detector and source. The differences in slope of calibration curves for different soils can be as much as 40%

Clinical Psychology Training: Accreditation and Beyond.

Levenson, Robert W

2017-05-08

Beginning with efforts in the late 1940s to ensure that clinical psychologists were adequately trained to meet the mental health needs of the veterans of World War II, the accreditation of clinical psychologists has largely been the province of the Commission on Accreditation of the American Psychological Association. However, in 2008 the Psychological Clinical Science Accreditation System began accrediting doctoral programs that adhere to the clinical science training model. This review discusses the goals of accreditation and the history of the accreditation of graduate programs in clinical psychology, and provides an overview of the evaluation procedures used by these two systems. Accreditation is viewed against the backdrop of the slow rate of progress in reducing the burden of mental illness and the changes in clinical psychology training that might help improve this situation. The review concludes with a set of five recommendations for improving accreditation.

With the increased use of techniques using neutron radiation, there has been a considerable growth in the number of detectors for this kind of radiation. A neutron calibration laboratory with neutron radiation ("2"4"1AmBe) was designed. In practical situations of this type of laboratory, one of the main problems is related to the knowledge of scattered radiation. In order to evaluate this scattered radiation, simulations were carried out without the presence of structural elements and with the complete room. Fourteen measuring points were evaluated in different directions at various distances. (author)

Bogh, Søren Bie; Blom, Ane; Raben, Ditte Caroline; Braithwaite, Jeffrey; Thude, Bettina; Hollnagel, Erik; Plessen, Christian von

2018-06-11

Purpose The purpose of this paper is to understand how staff at various levels perceive and understand hospital accreditation generally and in relation to quality improvement (QI) specifically. Design/methodology/approach In a newly accredited Danish hospital, the authors conducted semi-structured interviews to capture broad ranging experiences. Medical doctors, nurses, a quality coordinator and a quality department employee participated. Interviews were audio recorded and subjected to framework analysis. Findings Staff reported that The Danish Healthcare Quality Programme affected management priorities: office time and working on documentation, which reduced time with patients and on improvement activities. Organisational structures were improved during preparation for accreditation. Staff perceived that the hospital was better prepared for new QI initiatives after accreditation; staff found disease specific requirements unnecessary. Other areas benefited from accreditation. Interviewees expected that organisational changes, owing to accreditation, would be sustained and that the QI focus would continue. Practical implications Accreditation is a critical and complete hospital review, including areas that often are neglected. Accreditation dominates hospital agendas during preparation and surveyor visits, potentially reducing patient care and other QI initiatives. Improvements are less likely to occur in areas that other QI initiatives addressed. Yet, accreditation creates organisational foundations for future QI initiatives. Originality/value The authors study contributes new insights into how hospital staff at different organisational levels perceive and understand accreditation.

Laboratory-Based BRDF Calibration of Radiometric Tarps

Georgiev, Georgi T.; Butler, James J.

2007-01-01

The current study provides the remote sensing community with important high accuracy laboratory-based BRDF calibration of radiometric tarps. The results illustrate the dependence of tarps' weft and warp threads orientation on BRDF. The study was done at incident angles of 0deg, 10deg, and 30deg; scatter zenith angles from 0deg to 60deg, and scatter azimuth angles of 0deg, 45deg, 90deg, 135deg, and 180deg. The wavelengths were 485nm, 550nm, 633nm and 800nm. The dependence is well defined at all measurement geometries and wavelengths. It can be as high as 8% at 0deg incident angle and 2% at 30deg incident angle. The fitted BRDF data show a very small discrepancy from the measured ones. New data on the forward and backscatter properties of radiometric tarps is reported. The backward scatter is well pronounced for the white samples. The black sample has well pronounced forward scatter. The BRDF characterization of radiometric tarps can be successfully extended to other structured surface fabric samples. The results are NIST traceable.

Sinaga, A. S.; Girsang, A. S.

2017-01-01

The accreditation aims assuring the quality the quality of the institution education. The institution needs the comprehensive documents for giving the information accurately before reviewed by assessor. Therefore, academic documents should be stored effectively to ease fulfilling the requirement of accreditation. However, the data are generally derived from various sources, various types, not structured and dispersed. This paper proposes designing a data warehouse to integrate all various data to prepare a good academic document for accreditation in a university. The data warehouse is built using nine steps that was introduced by Kimball. This method is applied to produce a data warehouse based on the accreditation assessment focusing in academic part. The data warehouse shows that it can analyse the data to prepare the accreditation assessment documents.

New Submersed Chamber for Calibration of Relative Humidity Instruments at HMI/FSB-LPM

Sestan, D.; Zvizdic, D.; Sariri, K.

2018-02-01

This paper gives a detailed description of a new chamber designed for calibration of relative humidity (RH) instruments at Laboratory for Process Measurement (HMI/FSB-LPM). To the present time, the calibrations of RH instruments at the HMI/FSB-LPM were done by comparison method using a climatic chamber of large volume and calibrated dew point hygrometer with an additional thermometer. Since 2010, HMI/FSB-LPM in cooperation with Centre for Metrology and Accreditation in Finland (MIKES) developed the two primary dew point generators which cover the dew point temperature range between - 70 {°}C and 60 {°}C. In order to utilize these facilities for calibrations of the RH instruments, the new chamber was designed, manufactured and installed in the existing system, aiming to extend its range and reduce the related calibration uncertainties. The chamber construction allows its use in a thermostatic bath of larger volume as well as in the climatic chambers. In the scope of this paper, performances of the new chamber were tested while it was submersed in a thermostated bath. The chamber can simultaneously accommodate up to three RH sensors. In order to keep the design of the chamber simple, only cylindrical RH sensors detachable from display units can be calibrated. Possible optimizations are also discussed, and improvements in the design proposed. By using the new chamber, HMI/FSB-LPM reduced the expanded calibration uncertainties (level of confidence 95 %, coverage factor k=2) from 0.6 %rh to 0.25 %rh at 30 %rh (23 {°}C), and from 0.8 %rh to 0.53 %rh at 70 %rh (23 {°}C).

In the beginnings of the sixty years an urgent necessity is presented mainly in the developing countries, of improving in important form the accuracy in the dosimetry of external faces in therapy of radiations (radiotherapy centers), mainly in the calibration of c linical dosemeters . In 1976 the International Atomic Energy Agency, (IAEA), and the World Health Organization, (WHO), they carried out a mutual agreement with regard to the establishment and operation of a net of Secondary Patron Laboratories of Dosimetry, (LSCD). The necessity to establish measure patterns in the field of the dosimetry of the ionizing radiations, is necessary, to have an accuracy but high in the dosimetry of the radiation beams in therapy which is highly dependent of the dose given to the tumor of those patient with cancer. Similar levels of accuracy are required in protection measures to the radiation with an acceptable smaller accuracy, however, when the personal dosemeters are used to determine the doses received by the individuals under work conditions, such mensurations in therapy of radiations and radiological protection will have traceability through a chain of comparisons to primary or national patterns. The traceability is necessary to assure the accuracy and acceptability of the dosimetric measures, as well as, the legal and economic implications. The traceability is also necessary in the dosimetry of high dose like in the sterilization of different products. The main function of the LSCD is to provide a service in metrology of ionizing radiations, maintaining the secondary or national patterns, which have a traceability to the International System of measures, which is based for if same in the comparison of patterns in the Primary Laboratories of Dosimetry (LPD) under the auspice of the International Office of Weights and Measure (BIPM). The secondary and national patterns in the LSCD constitute in Mexico, the national patterns of the magnitudes in the dosimetry of the

WellCAP is a well control accreditation program devised and implemented by the International Association of Drilling Contractors (IADC). It is a worldwide comprehensive system that defines a well control training curriculum, establishes minimum standards and recommends guidelines for course structure. The program began in mid-1993 and is viewed as a means for training institutions to demonstrate industry recognition to customers, contractors and local governments. Schools can apply to have their courses accredited. The accreditation system is administered by a review panel. The application process requires that the school perform a detailed review of its curriculum and operations and bring them in line with the WellCAP curriculum and accreditation criteria. Currently, more than 75 schools around the world have requested application materials for WellCAP. To date fifteen schools have been fully accredited

Tracking Success: Outputs Versus Outcomes-A Comparison of Accredited and Non-Accredited Public Health Agencies' Community Health Improvement Plan objectives.

Perrault, Evan K; Inderstrodt-Stephens, Jill; Hintz, Elizabeth A

2018-06-01

With funding for public health initiatives declining, creating measurable objectives that are focused on tracking and changing population outcomes (i.e., knowledge, attitudes, or behaviors), instead of those that are focused on health agencies' own outputs (e.g., promoting services, developing communication messages) have seen a renewed focus. This study analyzed 4094 objectives from the Community Health Improvement Plans (CHIPs) of 280 local PHAB-accredited and non-accredited public health agencies across the United States. Results revealed that accredited agencies were no more successful at creating outcomes-focused objectives (35% of those coded) compared to non-accredited agencies (33% of those coded; Z = 1.35, p = .18). The majority of objectives were focused on outputs (accredited: 61.2%; non-accredited: 63.3%; Z = 0.72, p = .47). Outcomes-focused objectives primarily sought to change behaviors (accredited: 85.43%; non-accredited: 80.6%), followed by changes in knowledge (accredited: 9.75%; non-accredited: 10.8%) and attitudes (accredited: 1.6%; non-accredited: 5.1%). Non-accredited agencies had more double-barreled objectives (49.9%) compared to accredited agencies (32%; Z = 11.43, p < .001). The authors recommend that accreditation procedures place a renewed focus on ensuring that public health agencies strive to achieve outcomes. It is also advocated that public health agencies work with interdisciplinary teams of Health Communicators who can help them develop procedures to effectively and efficiently measure outcomes of knowledge and attitudes that are influential drivers of behavioral changes.

This work will present the concluded stages and also the ones that are still in process to reach the full automation of the calibration system. Little by little the laboratory included in its installations the automatization of some of its operations, aiming the safety of the staff and their equipment. The automation makes the installation almost ideal for the radioprotection, that is, makes its exposure as low as possible and the routines more accurate, minimizing attributed the uncertainties and the doses received by the professionals who operated the system manually. Currently, on the operation table there is a control of the position car exists and its speed, the internal TV circuit (of the room, the position of the car and equipment that is going to be calibrated), the control of the registration is done by the Autolab program and the Irradiator Buchler OB85 control with the sources of 137Cs and 60Co.A next stage will be the implantation of the automation project of the positioning of the three used attenuators.

The biochemical estimation of age in Euphausiids: Laboratory calibration and field comparisons

Harvey, H. R.; Ju, Se-J.; Son, S.-K.; Feinberg, L. R.; Shaw, C. T.; Peterson, W. T.

Euphausiids play a key role in many marine ecosystems as a link between primary producers and top predators. Understanding their demographic (i.e. age) structure is an essential tool to assess growth and recruitment as well as to determine how changes in environmental conditions might alter their condition and distribution. Age determination of crustaceans cannot be accomplished using traditional approaches, and here we evaluate the potential for biochemical products of tissue metabolism (termed lipofuscins) to determine the demographic structure of euphausiids in field collections . Lipofuscin was extracted from krill neural tissues (eye and eye-stalk), quantified using fluorescent intensity and normalized to tissue protein content to allow comparisons across animal sizes. Multiple fluorescent components from krill were observed, with the major product having a maximum fluorescence at excitation of 355 nm and emission of 510 nm. Needed age calibration of lipofuscin accumulation in Euphausia pacifica was accomplished using known-age individuals hatched and reared in the laboratory for over one year. Lipofuscin content extracted from neural tissues of laboratory-reared animals was highly correlated with the chronological age of animals ( r=0.87). Calibrated with laboratory lipofuscin accumulation rates, field-collected sub-adult and adult E. pacifica in the Northeast Pacific were estimated to be older than 100 days and younger than 1year. Comparative data for the Antarctic krill, E. superba showed much higher lipofuscin values suggesting a much longer lifespan than the more temperate species, E. pacifica. These regional comparisons suggest that biochemical indices allow a practical approach to estimate population age structure of diverse populations, and combined with other measurements can provide estimates of vital rates (i.e. longevity, mortality, growth) for krill populations in dynamic environments.

A trend in human and veterinary medical laboratory management is to achieve accreditation based on international standards. The International Organization for Standardization (ISO) 15189 standard is the first developed especially for accreditation of medical laboratories, and emphasizes the laboratory-client interface. European veterinary laboratories seeking to train candidates for the certification examination of the European College of Veterinary Clinical Pathology (ECVCP) require approval by the ECVCP Laboratory Standards Committee, which bases its evaluation in part on adherence to quality systems described in the ISO 15189 standards. The purpose of this article was to introduce the latest ISO quality standard and describe its application to veterinary laboratories in Europe, specifically as pertains to accreditation of laboratories involved in training veterinary clinical pathologists. Between 2003 and 2006, the Laboratory Standards Committee reviewed 12 applications from laboratories (3 commercial and 9 university) involved in training veterinary clinical pathologists. Applicants were asked to provide a description of the facilities for training and testing, current methodology and technology, health and safety policy, quality assurance policy (including internal quality control and participation in an external quality assurance program), written standard operating procedures (SOPs) and policies, a description of the laboratory information system, and personnel and training. Also during this time period multiple informal and formal discussions among ECVCP diplomates took place as to current practices and perceived areas of concern with regard to laboratory accreditation requirements. Areas in which improvement most often was needed in veterinary laboratories applying for ECVCP accreditation were the written quality plan, defined quality requirements for the tests performed, written SOPs and policies, training records, ongoing audits and competency

The Clinical Laboratory Improvement Amendments of 1988 (CLIA) requires all US clinical laboratories that test "materials derived from the human body for the purpose of providing information for the diagnosis, prevention, or treatment of any disease..." to be regulated. The CLIA mandates are site neutral; based on test complexity; and focus on the three phases of the testing process (preanalytical, analytical, and postanalytical). Many testing sites choose to meet the CLIA requirements by following the testing standards of a professional accreditation organization deemed by the Centers for Medicare and Medicaid Services. The three principal organizations are The Joint Commission, the College of American Pathologists, and COLA. Copyright © 2013 Elsevier Inc. All rights reserved.

Selecting clinical quality indicators for laboratory medicine.

Barth, Julian H

2012-05-01

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

Infrared spectra of two celestial objects frequently used as flux standards are calibrated against an absolute laboratory flux standard at a spectral resolving power of 100 to 200. The spectrum of the K1.5III star, alpha Boo, is measured from 3 microns to 30 microns and that of the C-type asteroid, 1 Ceres, from 5 microns to 30 microns. While these 'standard' spectra do not have the apparent precision of those based on calculated models, they do not require the assumptions involved in theoretical models of stars and asteroids. Specifically they provide a model-independent means of calibrating celestial flux in the spectral range from 12 microns to 30 microns where accurate absolute photometry is not available. The agreement found between the spectral shapes of alpha Boo and Ceres based on laboratory standards, and those based on observed ratios to alpha CMa (Sirius) and alpha Lyr (Vega), flux calibrated by theoretical modeling of these hot stars strengthens our confidence in the applicability of the stellar models as primary irradiance standards.

Physical therapy ultrasound is widely applied to patients. However, many devices do not comply with the relevant standard stating that the actual power output shall be within ±20% of the device indication. Extreme cases have been reported: from delivering effectively no ultrasound or operating at maximum power at all powers indicated. This can potentially lead to patient injury as well as mistreatment. The present European (EC) project is an ongoing attempt to improve the quality of the treatment of patients being treated with ultrasonic physical-therapy. A Portable ultrasound Power Standard (PPS) is being developed and accurately calibrated. The PPS includes: Ultrasound transducers (including one exhibiting an unusual output) and a driver for the ultrasound transducers that has calibration and proficiency test functions. Also included with the PPS is a Cavitation Detector to determine the onset of cavitation occurring within the propagation medium. The PPS will be suitable for conducting in-the-field accreditation (proficiency testing and calibration). In order to be accredited it will be important to be able to show traceability of the calibration, the calibration process and qualification of testing staff. The clinical user will benefit from traceability because treatments will be performed more reliably

Does the accreditation of private dental practices work? Time to rethink how accreditation can improve patient safety.

Jean, Gillian

2017-10-09

Accreditation to demonstrate engagement with the National Safety and Quality Health Service Standards (Standards) is compulsory for most hospital and healthcare settings, but to date remains voluntary for private dental practices (PDPs). The regulatory framework governing the dental profession lacks a proactive element to drive improvements in quality and safety of care, and an accreditation scheme can strengthen existing regulation. The current model of accreditation operating in accordance with the Australian Health Service Safety and Quality Accreditation Scheme (Scheme) is based on the Standards, which were written for a hospital model of healthcare service. The majority of PDPs are small office-based businesses with clear leadership structure and employing six staff or fewer. The Scheme is overly bureaucratic given the simplicity of the PDP business model. This article considers whether accreditation has a proven track record of improving quality of service and offers opinions about how a more appropriate safety management program for PDPs may look. What is known about the topic? There has been minimal research about the impact of accreditation schemes in improving patient safety in PDP. What does this paper add? This paper proposes a redesign of the Scheme to make it more relevant to PDPs. The paper offers strategies to minimise duplication of purpose between accreditation and existing legislation; and to strengthen critical elements of accreditation to improve effects on patient safety. What are the implications for practitioners? A redesigned accreditation scheme will support dental practitioners to implement a quality assurance system with improved efficiency, reduced administrative burden, and optimised patient safety.

Nine simple minerals and oxides, traditionally used as laboratory reference samples in the electron probe microanalysis (EPMA) of silicate minerals, have been quantitatively evaluated. Three separate series of data, comprising the average concentration, standard deviation, relative standard deviation, confidence interval and the z-score of data quality, were calculated for 21 control samples derived from calibrations obtained from three sets of reference samples: (1) simple minerals; (2) oxides; and (3) certified glass reference materials. No systematic difference was observed between the concentrations obtained from these three calibration sets when analyzed results were compared to certified compositions. The relative standard deviations obtained for each element were smaller than target values for all determinations. The z-score values for all elements determined fell within acceptable limits (-2< z<2) for concentrations ranging from 0.1 to 100%. These experiments show that the quality of data obtained from laboratory reference calibration samples is not inferior to that from certified reference glasses. The quality of results obtained corresponds to the 'applied geochemistry' type of analysis (category 2) as defined in the GeoPT proficiency testing program. Therefore, the laboratory reference samples can be used for calibrating EPMA techniques in the analysis of silicate minerals and for controlling the quality of results

The purposes of this study were to (1) determine the proportion of plastic surgery residents pursuing subspecialty training relative to other surgical specialties, and (2) analyze trends in Accreditation Council for Graduate Medical Education accreditation of plastic surgery subspecialty fellowship programs. The American Medical Association provided data on career intentions of surgical chief residents graduating from 2014 to 2016. The percentage of residents pursuing fellowship training was compared by specialty. Trends in the proportion of accredited fellowship programs in craniofacial surgery, hand surgery, and microsurgery were analyzed. The percentage of accredited programs was compared between subspecialties with added-certification options (hand surgery) and subspecialties without added-certification options (craniofacial surgery and microsurgery). Most integrated and independent plastic surgery residents pursued fellowship training (61.8 percent versus 49.6 percent; p = 0.014). Differences existed by specialty from a high in orthopedic surgery (90.8 percent) to a low in colon and rectal surgery (3.2 percent). From 2005 to 2015, the percentage of accredited craniofacial fellowship programs increased, but was not significant (from 27.8 percent to 33.3 percent; p = 0.386). For hand surgery, the proportion of accredited programs that were plastic surgery (p = 0.755) and orthopedic surgery (p = 0.253) was stable, whereas general surgery decreased (p = 0.010). Subspecialty areas with added-certification options had more accredited fellowships than those without (100 percent versus 19.2 percent; p < 0.001). There has been slow adoption of accreditation among plastic surgery subspecialty fellowships, but added-certification options appear to be highly correlated.

Health and safety in clinical laboratories is becoming an increasingly important subject as a result of emergence of highly infectious diseases such as Hepatitis and HIV. A cross sectional study was carried out to study the safety measures being adopted in clinical laboratories of India. Heads of laboratories of teaching hospitals of India were subjected to a standardized, pretested questionnaire. Response rate was 44.8%. only 60% of laboratories had person in-charge of safety in laboratory. Seventy three percent of laboratories had safety education program regarding hazards. In 91% of laboratories staff is using protective clothing while working in laboratories. Hazardous material regulations are followed in 78% of laboratories. Regular health check ups are carried among laboratory staff in 43.4% of laboratories.Safety manual is available in 56.5% of laboratories. 73.9% of laboratories are equipped with fire extinguishers. Fume cupboards are provided in 34.7% of laboratories and they are regularly checked in 87.5% of these laboratories. In 78.26% of laboratories suitable measures are taken to minimize formation of aerosols.In 95.6% of laboratories waste is disposed off as per bio-medical waste management handling rules. Laboratory of one private medical college was accredited with NABL and safety parameters were better in that laboratory. Installing safety engineered devices apparently contributes to significant decrease in injuries in laboratories; laboratory safety has to be a part of overall quality assurance programme in hospitals. Accreditation has to be made necessary for all laboratories.

2006-01-01

In recent decades, medical imaging has experienced a technological revolution. After conducting several surveys to assess the quality and safety of diagnostic imaging services in Latin America and the Caribbean, the Pan American Health Organization (PAHO) developed a basic accreditation program that can be implemented by the ministry of health of any developing country. Patterned after the American College of Radiology's accreditation program, the PAHO program relies on a national accreditation committee to establish and maintain accreditation standards. The process involves a peer review evaluation of: (1) imaging and processing equipment, (2) physician and technologist staff qualifications, (3) quality control and quality assurance programs, and (4) image quality and, where applicable, radiation dose. Public and private conventional radiography/fluoroscopy, mammography, and ultrasound services may request accreditation. The radiography/fluoroscopy accreditation program has three modules from which to choose: chest radiography, general radiography, and fluoroscopy. The national accreditation committee verifies compliance with the standards. On behalf of the ministry of health, the accreditation committee also issues a three-year accreditation certificate. As needed, the accreditation committee consults with foreign technical and clinical experts.

Laboratory accreditation provides a level of standardization in laboratories and confidence in generated food and feed testing results. For some laboratories, ISO/IEC 17025:2005 accreditation may not be fiscally viable, or a requested test method may be out of the scope of the laboratory's accreditation. To assist laboratories for whom accreditation is not feasible, the Association of Public Health Laboratories Data Acceptance Work Group developed a white paper entitled "Best Practices for Submission of Actionable Food and Feed Testing Data Generated in State and Local Laboratories." The basic elements of a quality management system, along with other best practices that state and local food and feed testing laboratories should follow, are included in the white paper. It also covers program-specific requirements that may need to be addressed. Communication with programs and end data users is regarded as essential for establishing the reliability and accuracy of laboratory data. Following these suggested best practices can facilitate the acceptance of laboratory data, which can result in swift regulatory action and the quick removal of contaminated product from the food supply, improving public health nationally.

Background Quality indicators determine the quality of actual practice in reference to standard criteria. The Community Pharmacy Association (Thailand), with technical support from the International Pharmaceutical Federation, developed a tool for quality assessment and quality improvement at community pharmacies. This tool has passed validity and reliability tests, but has not yet had feasibility testing. Objective (1) To test whether this quality tool could be used in routine settings. (2) To compare quality scores between accredited independent and accredited chain pharmacies. Setting Accredited independent pharmacies and accredited chain pharmacies in the north eastern region of Thailand. Methods A cross sectional study was conducted in 34 accredited independent pharmacies and accredited chain pharmacies. Quality scores were assessed by observation and by interviewing the responsible pharmacists. Data were collected and analyzed by independent t-test and Mann-Whitney U test as appropriate. Results were plotted by histogram and spider chart. Main outcome measure Domain's assessable scores, possible maximum scores, mean and median of measured scores. Results Domain's assessable scores were close to domain's possible maximum scores. This meant that most indicators could be assessed in most pharmacies. The spider chart revealed that measured scores in the personnel, drug inventory and stocking, and patient satisfaction and health promotion domains of chain pharmacies were significantly higher than those of independent pharmacies (p pharmacies and chain pharmacies in the premise and facility or dispensing and patient care domains. Conclusion Quality indicators developed by the Community Pharmacy Association (Thailand) could be used to assess quality of practice in pharmacies in routine settings. It is revealed that the quality scores of chain pharmacies were higher than those of independent pharmacies.

Scoping medical tourism and international hospital accreditation growth.

Woodhead, Anthony

2013-01-01

Uwe Reinhardt stated that medical tourism can do to the US healthcare system what the Japanese automotive industry did to American carmakers after Japanese products developed a value for money and reliability reputation. Unlike cars, however, healthcare can seldom be test-driven. Quality is difficult to assess after an intervention (posteriori), therefore, it is frequently evaluated via accreditation before an intervention (a priori). This article aims to scope the growth in international accreditation and its relationship to medical tourism markets. Using self-reported data from Accreditation Canada, Joint Commission International (JCI) and Australian Council on Healthcare Standards (ACHS), this article examines how quickly international accreditation is increasing, where it is occurring and what providers have been accredited. Since January 2000, over 350 international hospitals have been accredited; the JCI's total nearly tripling between 2007-2011. Joint Commission International staff have conducted most international accreditation (over 90 per cent). Analysing which countries and regions where the most international accreditation has occurred indicates where the most active medical tourism markets are. However, providers will not solely be providing care for medical tourists. Accreditation will not mean that mistakes will never happen, but that accredited providers are more willing to learn from them, to varying degrees. If a provider has been accredited by a large international accreditor then patients should gain some reassurance that the care they receive is likely to be a good standard. The author questions whether commercializing international accreditation will improve quality, arguing that research is necessary to assess the accreditation of these growing markets.

Full Text Available Achieving accreditation in laboratories is a challenge in Nigeria like in most African countries. Nigeria adopted the World Health Organization Regional Office for Africa Stepwise Laboratory (Quality Improvement Process Towards Accreditation (WHO/AFRO- SLIPTA in 2010. We report on FHI360 effort and progress in piloting WHO-AFRO recognition and accreditation preparedness in six health facility laboratories in five different states of Nigeria.Laboratory assessments were conducted at baseline, follow up and exit using the WHO/AFRO- SLIPTA checklist. From the total percentage score obtained, the quality status of laboratories were classified using a zero to five star rating, based on the WHO/AFRO quality improvement stepwise approach. Major interventions include advocacy, capacity building, mentorship and quality improvement projects.At baseline audit, two of the laboratories attained 1- star while the remaining four were at 0- star. At follow up audit one lab was at 1- star, two at 3-star and three at 4-star. At exit audit, four labs were at 4- star, one at 3-star and one at 2-star rating. One laboratory dropped a 'star' at exit audit, while others consistently improved. The two weakest elements at baseline; internal audit (4% and occurrence/incidence management (15% improved significantly, with an exit score of 76% and 81% respectively. The elements facility and safety was the major strength across board throughout the audit exercise.This effort resulted in measurable and positive impact on the laboratories. We recommend further improvement towards a formal international accreditation status and scale up of WHO/AFRO- SLIPTA implementation in Nigeria.

Beyond accreditation: excellence in medical education.

Medical school accreditation is a relatively new phenomenon in Korea. The development of an accreditation body and standards for a two-tiered "Must" and "Should" system in 1997 eventually led to the implementation of a third "Excellence" level of attainment. These standards were conceived out of a desire to be able to first recognize and promote outstanding performance of medical schools, second to provide role models in medical education, and furthermore to preview the third level as potential components of the pre-existing second level for the next accreditation cycle. It is a quality-assurance mechanism that, while not required for accreditation itself, pushes medical schools to go beyond the traditional requirements of mere pass-or-fail accreditation adequacy, and encourages schools to deliver an unprecedented level of medical education. The Association for Medical Education in Europe developed its own third-tier system of evaluation under the ASPIRE project, with many similar goals. Due to its advanced nature and global scope, the Korean accreditation body has decided to implement the ASPIRE system in Korea as well.

Programme implementation: The SLMTA programme entailed hands-on learning, improvement projects between and after a three-workshop series, supervisory visits from an oversight team and an expert laboratory mentor to facilitate and coach the process. Audits were conducted at baseline, exit (approximately one year after baseline and follow-up (seven months after exit using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA checklist. Quality stars (zero to five were awarded based on audit scores. Results: With a dedicated staff and strong leadership from laboratory management, Amana Laboratory implemented processes, policies and procedures recommended as elements of best laboratory practices. The laboratory improved from zero stars (36% at baseline to successfully achieving three stars (81% at exit. This was the highest score achieved by the 12 laboratories in the programme (the median exit score amongst the other laboratories was 58%. Seven months after completion of the programme, the laboratory regressed to one star (62%. Discussion: As the SLMTA improvement programme progressed, Amana Laboratory’s positive attitude and hard work prevailed. With the assistance of a mentor and the support of the facility’s management a strong foundation of good practices was established. Although not all improvements were maintained after the conclusion of the programme and the laboratory dropped to a one-star rating, the laboratory remained at a higher level than most laboratories in the programme.

Quality in health care is important as it is directly linked with patient safety. Quality as we know is driven either by regulation or by market demand. Regulation in most developing countries has not been effective, as there is shortage of health care providers and governments have to be flexible. In such circumstances, quality has taken a back seat. Accreditation symbolizes the framework for quality governance of a hospital and is based on optimum standards. Not only is India establishing numerous state of the art hospitals, but they are also experiencing an increase in demand for quality as well as medical tourism. India launched its own accreditation system in 2006, conforming to standards accredited by ISQua. This article shows the journey to accreditation in India and describes the problems encountered by hospitals as well as the benefits it has generated for the industry and patients.

The employment in the Center of Radiation Protection and Hygiene (CRPH) of Cuba, of the standard 17025 for the administration of the quality of the calibration laboratories and test that offer services of radiological protection requires of a technical complement to really determine the technical competence. In the standard 17025, the specific requirements, are mentioned in the annex B (with informative character), where it points out that: {sup T}he requirements specified in the standard 17025 are established in general terms and, although they can be applied to all the test laboratories and applications, they could be necessary applications{sup .} In the CRPH these applications are translated in indispensable technical requirements to evaluate the performance of the services of radiological protection that offers, specifically those of personal monitoring, the calibration of instruments and the metrology of radionuclides. Although the standard 17025 is quite rigorous in the evaluation of technical requirements, to have specific materials not serves alone of tool to the laboratories, but also for the body of accreditation . In the CRPH the permanent employment of this tool has not constituted a practice, but had been good before our clients certain nonconformities to evaluate the performance of the laboratory and to achieve the recovery of the trust in its results. With this work we seek to expose some of these experiences. The experiences of the application of some of the technical requirements, in our case, they have been applied to the service of personal monitoring that offers the Laboratory of Personal Dosimetry. This laboratory is accredited by the National Accreditation Board of the Republic of Cuba (NABC) and besides fulfilling that settled down in 17025, the Approaches of Accreditation for test laboratories and calibration and it should also implant that settled down as specific technical requirements for the recognition of technical competence.

The UNE-EN-ISO 15189:2007 standard defines the requirements for quality and competence that must be met by medical laboratories. These laboratories should use this international standard to develop their own quality management systems and to evaluate their own competencies; in turn, this standard will be used by accreditation bodies to confirm or recognize the laboratories' competence. In clinical microbiology laboratories, application of the standard implies the implementation of the technical and specific management requirements that must be met to achieve optimal quality when carrying out microbiological tests. In Spain, accreditation is granted by the Spanish Accreditation Body (Entidad Nacional de Acreditación). This review aims to discuss the practical application of the standard's technical requirements in mycobacterial laboratory. Firstly, we define the scope of accreditation. Secondly, we specify how the items of the standard on personnel management, control of equipment, environmental facilities, method validation, internal controls and customer satisfaction surveys were developed and implemented in our laboratory.

Full Text Available According to William Edwards Deming “Good quality does not necessarily mean high quality. Instead it means a predicable degree of uniformity and dependability at low cost with a quality suited to the market.” Whereas according to famous engineer and management consultant Joseph M. Juran quality is “fitness for purpose”. It should meet the customers’ expectations and requirements, should be cost effective.ISO began in 1926 as the International Federation of the National Standardizing Associations (ISA. The name, "ISO" was derived from the Greek word "isos" meaning "equal". (The relation to standards is that if two objects meet the same standard, they should be equal. This name eliminates any confusion that could result from the translation of "International Organization for Standardization" into different languages which would lead to different acronyms.In health sector, quality plays pivotal role, as it is directly related to patient’s care. Earlier time, health service was simple, quite safe but ineffective. Now health care system is an organizational system with more complex processes to deliver care. Medical laboratory service is an integral part in patient’s management system. So, for everyone involved in the treatment of the patient, the accuracy, reliability and safety of those services must be the primary concerns. Accreditation is a significant enabler of quality, thereby delivering confidence to healthcare providers, clinicians, the medical laboratories and the patients themselves.ISO announced meeting in Philadelphia to form a technical committee to develop a new standard for medical laboratory quality. It took 7 years for the creation of a new Quality standard for medical laboratories. It was named as “ISO 15189” and was first published in 2003. The ISO has released three versions of the standard. The first two were released in 2003 and 2007. In 2012, a revised and updated version of the standard, ISO 15189

A challenging problem in designing pilot-scale carbon capture systems is to predict, with uncertainty, the adsorber performance and capture efficiency under various operating conditions where no direct experimental data exist. Motivated by this challenge, we previously proposed a hierarchical framework in which relevant parameters of physical models were sequentially calibrated from different laboratory-scale carbon capture unit (C2U) experiments. Specifically, three models of increasing complexity were identified based on the fundamental physical and chemical processes of the sorbent-based carbon capture technology. Results from the corresponding laboratory experiments were used to statistically calibrate the physical model parameters while quantifying some of their inherent uncertainty. The parameter distributions obtained from laboratory-scale C2U calibration runs are used in this study to facilitate prediction at a larger scale where no corresponding experimental results are available. In this paper, we first describe the multiphase reactive flow model for a sorbent-based 1-MW carbon capture system then analyze results from an ensemble of simulations with the upscaled model. The simulation results are used to quantify uncertainty regarding the design’s predicted efficiency in carbon capture. In particular, we determine the minimum gas flow rate necessary to achieve 90% capture efficiency with 95% confidence.

[Accreditation of Independent Ethics Committees].

Science.gov (United States)

Ramiro Avilés, Miguel A

According to Law 14/2007 and Royal Decree 1090/2015, biomedical research must be assessed by an Research Ethics Committee (REC), which must be accredited as an Research ethics committee for clinical trials involving medicinal products (RECm) if the opinion is issued for a clinical trial involving medicinal products or clinical research with medical devices. The aim of this study is to ascertain how IEC and IECm accreditation is regulated. National and regional legislation governing biomedical research was analysed. No clearly-defined IEC or IECm accreditation procedures exist in the national or regional legislation. Independent Ethics Committees are vital for the development of basic or clinical biomedical research, and they must be accredited by an external body in order to safeguard their independence, multidisciplinary composition and review procedures.

A mammography calibration facility has been established in the Medical Physics Laboratory, Malaysian Institute for Nuclear Technology Research (MINT). The calibration facility is established at the national level mainly to provide calibration services for radiation measuring test instruments or test tools used in quality assurance programme in mammography, which is being implemented in Malaysia. One of the accepted parameters that determine the quality of a radiation beam is the homogeneity coefficient. It is determined from the values of the 1 st and 2 nd Half Value Layer (HVL). In this paper, the consistency of the mammography machine beam qualities that is available in MINT, is investigated and presented. For calibration purposes, five radiation qualities namely 23, 25, 28, 30 and 35 kV, selectable from the control panel of the X-ray machine is used. Important parameters that are set for this calibration facility are exposure time, tube current, focal spot to detector distance (FDD) and beam size at specific distance. The values of homogeneity coefficient of this laboratory for the past few years tip to now be presented in this paper. Backscatter radiations are also considered in this investigation. (Author)

AUDILAB: a knowledge-based quality audit simulator for testing laboratories.

Brai, A; Garnerin, P

1997-05-01

In order to obtain an accreditation, a laboratory must be prepared to provide a point-by-point check of various activities against the chosen reference standard, both from a general point of view and in relation to details of application. This paper describes AUDILAB, a computerized simulator accessible by network, able to provide testing laboratories with realistic quality audits performed in a customized way. AUDILAB establishes a detailed list of strengths (compliance with corresponding requirements of established standards) and weaknesses (improvements needed for laboratory's accreditation). The standard used by AUDILAB is the EN 45001 "General criteria for the operation of testing laboratories". A preliminary validation has already been completed. AUDILAB became operational in September 1993.

establish a network of national veterinary diagnostic testing laboratories that are recognized for their achievements in establishing QA systems and their proficiency in the use of specific diagnostic assays. This network would facilitate the exchange of epidemiological information and, in the current atmosphere of international and regional trade agreements, provide a greater opportunity to increase the share of developing countries in the international trade of livestock and livestock products. In February 1998, a Consultants' Meeting was convened to consider the design, impact, and proposals for future implementation of the current FAO/IAEA EQAP for Animal Disease Diagnosis and make recommendations with regard to its central purposes and future direction. In addition, the Consultants considered the broader question of a generic QA 'accreditation' scheme for veterinary diagnostic testing laboratories that could be made available through international, regional, or national organizations as appropriate to the country of interest. This broader discussion was stimulated by the fact that few developed and no developing countries have nationally organized schemes to measure and recognize the QA systems and technical competence of veterinary diagnostic testing laboratories, but that such a scheme is of vital importance to the quality of policy decisions and actions taken on national animal health issues and the international trade of livestock and livestock commodities. It followed that, in the Subprogramme's role as a Collaborating Centre to the Office International Epizooties (OIE, or World Animal Health Organization), it would be appropriate to consider the FAO/IAEA EQAP within the broader scope of an international scheme for veterinary diagnostic laboratory accreditation for two reasons: 1) to use information learned through the design and implementation of the FAO/IAEA EQAP to assist in the appropriate development of an international scheme and 2) to ensure that the FAO

The concept of measurement quality assurance (MQA) as embodied in National Institute of Standards and Technology (NIST) programs is not generally used within European programs for testing or accreditation. Although the essential elements of quality control and quality assurance are in the European programs, the concept of testing the capability of the laboratory itself, in terms of its performance for the designated measurements, may not be included. Rather, the European programs use the concept of periodic calibration of laboratory reference standards against the next highest level of standards. Thus, they embody the concept of measurement traceability to appropriate primary standards. Within Europe a series of calibration accreditation programs has been established in the various countries tied together through a multilateral agreement. The radiation measurement programs are based on the International Organization for Standardization (ISO) 9000 series of standards. The purpose of this paper is to outline the overall operation of European Accreditation Programs in the radiation calibration and measurement areas. The operation of the radiation measurement programs of the National Measurement Accreditation Service (NAMAS) in the United Kingdom is described in detail along with other European programs. The manner in which these programs relate to individual dosimetry service programs is also described

Past efforts to improve laboratory quality systems and to achieve accreditation for better patient care in the Caribbean Region have been slow. To describe the impact of the Strengthening of Laboratory Management Toward Accreditation (SLMTA) training programme and mentorship amongst five clinical laboratories in the Caribbean after 18 months. Five national reference laboratories from four countries participated in the SLMTA programme that incorporated classroom teaching and implementation of improvement projects. Mentors were assigned to the laboratories to guide trainees on their improvement projects and to assist in the development of Quality Management Systems (QMS). Audits were conducted at baseline, six months, exit (at 12 months) and post-SLMTA (at 18 months) using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) checklist to measure changes in implementation of the QMS during the period. At the end of each audit, a comprehensive implementation plan was developed in order to address gaps. Baseline audit scores ranged from 19% to 52%, corresponding to 0 stars on the SLIPTA five-star scale. After 18 months, one laboratory reached four stars, two reached three stars and two reached two stars. There was a corresponding decrease in nonconformities and development of over 100 management and technical standard operating procedures in each of the five laboratories. The tremendous improvement in these five Caribbean laboratories shows that SLMTA coupled with mentorship is an effective, user-friendly, flexible and customisable approach to the implementation of laboratory QMS. It is recommended that other laboratories in the region consider using the SLMTA training programme as they engage in quality systems improvement and preparation for accreditation.

This work presents a methodology for the X radiation qualities characterization following the new recommendations of the standard 61267 of the International Electrotechnical Commission (IEC) to establish a new procedure for calibration of dosimetric systems used in the field of diagnostic radiology. The reference qualities radiation of IEC 61267: RQR 2 to RQR 10, RQA 2 to RQA 10, RQB 2 to RQB 10 and RQN 2 to RQN 10 were implanted at the calibration laboratory of IPEN (LCI). Their characteristics were analyzed through measurements of beam parameters such as: Practical peak voltage (PPV), specific additional filtrations for each qualities (high purity aluminum of about 99.9%), 1st and 2nd Half Value Layers, homogeneity coefficient. The inherent filtration of the X ray tube was also determined. With the establishment of these radiation qualities, the LCI will be ready to calibrate the measuring instruments of radiation in the new qualities, allowing an improvement in radiological services offered by IPEN.

This study aimed to explore the perceptions of medical students in a developing medical education system towards international accreditation. Applicants to an Internal Medicine residency program in an academic medical center in the United Arab Emirates (UAE) accredited by the Accreditation Council for Graduate Medical Education-International (ACGME-I) were surveyed between May and June 2014. The authors analysed responses using inductive qualitative thematic analysis to identify emergent themes. Seventy-eight of 96 applicants (81%) completed the survey. The vast majority of respondents 74 (95%) reported that ACGME-I accreditation was an important factor in selecting a residency program. Five major themes were identified, namely improving the quality of education, increasing opportunities, meeting high international standards, improving program structure, and improving patient care. Seven (10%) of respondents felt they would be in a position to pursue fellowship training or future employment in the United States upon graduation from an ACGME-I program. UAE trainees have an overwhelmingly positive perception of international accreditation, with an emphasis on improving the quality of training provided. Misperceptions, however, exist about potential opportunities available to graduates of ACGME-I programs. As more countries adopt the standards of the ACGME-I or other international accrediting bodies, it is important to recognize and foster trainee "buy-in" of educational reform initiatives.

The Instituto de Radioprotecao e Dosimetria (IRD) runs a neutron individual monitoring service with albedo type monitor and thermoluminescent detectors (TLD). Moreover the largest number of workers exposed to neutrons in Brazil is exposed to 241 Am-Be fields. Therefore a study of the response of albedo dosemeter due to neutron scattering from 241 Am-Be source is important for a proper calibration. In this work, it has been evaluated the influence of the scattering correction in two distances at the Low Scattering Laboratory of the Neutron Laboratory of the Brazilian National Laboratory (Lab. Nacional de Metrologia Brasileira de Radiacoes Ionizantes) in the calibration of that albedo dosemeter for a 241 Am-Be source. (author)

2017-12-01

In anticipation of a revision to the Standards for Accreditation, the Phyisician Assistant Education Association (PAEA) charged a small task force to develop a strategy for engaging its members in the revision process. Rather than focusing on the current Standards, the task force members recommend a backward design approach to determine the desired outcomes of a successful revision to the Standards. Ultimately, the group believes that shifting to a profession-defined, outcomes-based model for accreditation will allow for greater innovation in physician assistant education and reduce the strain on programs facing resource limitations, particularly clinical site shortages. Task force members value accreditation and urge a paradigm shift in the Standards revision process to focus on meaningful educational outcomes that lead to enhanced program quality and patient safety.

Accreditation programmes aim to improve the quality and safety of health services, and have been widely implemented. However, there is conflicting evidence regarding the outcomes of existing programmes. The Accreditation Collaborative for the Conduct of Research, Evaluation and Designated Investigations through Teamwork-Current Accreditation Processes (ACCREDIT-CAP) project is designed to address key gaps in the literature by evaluating the current processes of three accreditation programmes used across Australian acute, primary and aged care services. The project comprises three mixed-method studies involving documentary analyses, surveys, focus groups and individual interviews. Study samples will comprise stakeholders from across the Australian healthcare system: accreditation agencies; federal and state government departments; consumer advocates; professional colleges and associations; and staff of acute, primary and aged care services. Sample sizes have been determined to ensure results allow robust conclusions. Qualitative information will be thematically analysed, supported by the use of textual grouping software. Quantitative data will be subjected to a variety of analytical procedures, including descriptive and comparative statistics. The results are designed to inform health system policy and planning decisions in Australia and internationally. The project has been approved by the University of New South Wales Human Research Ethics Committee (approval number HREC 10274). Results will be reported to partner organisations, healthcare consumers and other stakeholders via peer-reviewed publications, conference and seminar presentations, and a publicly accessible website.

Antinuclear antibodies (ANA) are useful biomarkers for the diagnosis and the monitoring of rheumatic diseases. The American College of Rheumatology has stated that indirect immunofluorescence (IIF) analysis remains the gold standard for ANA screening. However, IIF is time consuming, subjective, not fully standardized and presents several issues for accreditation which is the process leading to ISO 15189 certification for medical laboratories. We propose an innovative tool for accreditation by using the quantitative evaluation of the automated image capture and analysis "ICARE" (Immunofluorescence for Computed Antinuclear antibody Rational Evaluation). We established the optimal screening dilution (1:160) and a fluorescence index (FI) cutoff for ICARE on a cohort of 91 healthy blood donors. Then, we evaluated performance of ICARE on a routine cohort of 236 patients. Precision parameters of ANA detection by IIF were evaluated according to ISO 15189. ICARE showed an excellent concordance with visual evaluation (88%, Kappa=0.76) and significantly discriminated between weak to moderate (1:160-1:320 titers) and high (>1:320 titers) ANA levels. A significant correlation was found between FI and ANA titers (Spearman's ρ=0.67; Pprocess of continuous improvement of the quality of clinical laboratories. Copyright © 2015 Elsevier B.V.

Mammography accreditation program

Energy Technology Data Exchange (ETDEWEB)

Wilcox, P.

1993-12-31

In the mid-1980`s, the movement toward the use of dedicated mammography equipment provided significant improvement in breast cancer detection. However, several studies demonstrated that this change was not sufficient to ensure optimal image quality at a low radiation dose. In particular, the 1985 Nationwide Evaluation of X-ray Trends identified the wide variations in image quality and radiation dose, even from dedicated units. During this time period, the American Cancer Society (ACS) launched its Breast Cancer Awareness Screening Campaign. However, there were concerns about the ability of radiology to respond to the increased demand for optimal screening examinations that would result from the ACS program. To respond to these concerns, the ACS and the American College of Radiology (ACR) established a joint committee on mammography screening in 1986. After much discussion, it was decided to use the ACR Diagnostic Practice Accreditation Program as a model for the development of a mammography accreditation program. However, some constraints were required in order to make the program meet the needs of the ACS. This voluntary, peer review program had to be timely and cost effective. It was determined that the best way to address these needs would be to conduct the program by mail. Finally, by placing emphasis on the educational nature of the program, it would provide an even greater opportunity for improving mammographic quality. The result of this effort was that, almost six years ago, in May 1987, the pilot study for the ACR Mammography Accreditation Program (MAP) began, and in August of that year, the first applications were received. In November 1987, the first 3-year accreditation certificates were awarded.

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.

Two laboratory methods for the calibration of GPS speed meters

International Nuclear Information System (INIS)

Bai, Yin; Sun, Qiao; Du, Lei; Yu, Mei; Bai, Jie

2015-01-01

The set-ups of two calibration systems are presented to investigate calibration methods of GPS speed meters. The GPS speed meter calibrated is a special type of high accuracy speed meter for vehicles which uses Doppler demodulation of GPS signals to calculate the measured speed of a moving target. Three experiments are performed: including simulated calibration, field-test signal replay calibration, and in-field test comparison with an optical speed meter. The experiments are conducted at specific speeds in the range of 40–180 km h −1 with the same GPS speed meter as the device under calibration. The evaluation of measurement results validates both methods for calibrating GPS speed meters. The relative deviations between the measurement results of the GPS-based high accuracy speed meter and those of the optical speed meter are analyzed, and the equivalent uncertainty of the comparison is evaluated. The comparison results justify the utilization of GPS speed meters as reference equipment if no fewer than seven satellites are available. This study contributes to the widespread use of GPS-based high accuracy speed meters as legal reference equipment in traffic speed metrology. (paper)

Field and laboratory calibration of neutron probes for soil moisture measurements on a deep loess chernozem soil

International Nuclear Information System (INIS)

Schaecke, B.; Schaecke, E.

1979-01-01

In the case of a varying profile structure it is necessary to use different calibration curves and adequate correction factors, respectively. The bulk density of the soil had the greatest influence on the calibration. An increase in bulk density by 0.2 g/cm 3 at a clay content of 18% resulted in an apparent increase in the values of moisture measurements by 1.5 to 2.0% of the volume of water. In naturally stratified soil the humus content of the chernozem horizon, being 3% higher than that of the underlying loess horizon, was found to influence the measuring results obtained by the probe. The calibration curves determined for chernozem and loess horizons in the laboratory agreed well with those obtained in the field. The measured values read from the probe and the gravimetrically determined values of the soil moisture were of great significance in all measured depths of the profile. (author)

Chronic bee paralysis virus (CBPV) is responsible for chronic bee paralysis, an infectious and contagious disease in adult honey bees (Apis mellifera L.). A real-time RT-PCR assay to quantitate the CBPV load is now available. To propose this assay as a reference method, it was characterised further in an intra-laboratory study during which the reliability and the repeatability of results and the performance of the assay were confirmed. The qPCR assay alone and the whole quantitation method (from sample RNA extraction to analysis) were both assessed following the ISO/IEC 17025 standard and the recent XP U47-600 standard issued by the French Standards Institute. The performance of the qPCR assay and of the overall CBPV quantitation method were validated over a 6 log range from 10(2) to 10(8) with a detection limit of 50 and 100 CBPV RNA copies, respectively, and the protocol of the real-time RT-qPCR assay for CBPV quantitation was approved by the French Accreditation Committee.

Gomes, Erica Cupertino

2005-03-01

The main purpose of this work is to update the PSA study of the Radiation Monitor Calibration Laboratory of the Almirante Alvaro Alberto Power Station taking into account new information. It is considered in this study an evaluation of the human reliability analysis in the calibration procedure of the radiation monitors, and for such the THERP modeling is used, as well as the use of the Bayesian approach for the calculation of the equipment failure probabilities used by the operators. Some accident scenarios of external origin were incorporated for evaluating their importance for an accident that might expose a worker to gamma radiation. A catastrophic failure is analyzed in the diesel generators 3 and 4, whose building is nearby the laboratory, as well as the route of change and the transportation of the steam generator of the nuclear power plant since the laboratory is located in the plant controlled area. Although more accidents scenarios are considered in this work, a conservative approach was not used and thus a smaller radiological risk was obtained. (author)

Does external evaluation of laboratories improve patient safety?

2007-01-01

Laboratory accreditation and External Quality Assessment (also called proficiency testing) are mainstays of laboratory quality assessment and performance. Both practices are associated with examples of improved laboratory performance. The relationship between laboratory performance and improved patient safety is more difficult to assess because of the many variables that are involved with patient outcome. Despite this difficulty, the argument to continue external evaluation of laboratories is too compelling to consider the alternative.

The discussion addresses the reasons for different types of surveys and how the surveys and the Hospital Information Form are used in evaluating a graduate residency program in radiology for accreditation. The Residency Review Committee for Radiology (RRC) and the staff of the Accreditation Council for Graduate Medical Education (ACGME) of Residencies in Radiology offer a program for program directors and other interested leaders in graduate programs in radiology. The authors explain the review and accreditation process for residencies in radiology with special emphasis on the preparation for inspection by accurate and full completion of the Hospital Information Form on which the program is judged, and the nature of the inspection procedures

Guidelines on calibration of neutron measuring devices

International Nuclear Information System (INIS)

Burger, G.

1988-01-01

The International Atomic Energy Agency and the World Health Organization have agreed to establish an IAEA/WHO Network of Secondary Standard Dosimetry Laboratories (SSDLs) in order to improve accuracy in applied radiation dosimetry throughout the world. These SSDLs must be equipped with, and maintain, secondary standard instruments, which have been calibrated against primary standards, and must be nominated by their governments for membership of the network. The majority of the existing SSDLs were established primarily to work with photon radiation (X-rays and gamma rays). Neutron sources are, however, increasingly being applied in industrial processes, research, nuclear power development and radiation biology and medicine. Thus, it is desirable that the SSDLs in countries using neutron sources on a regular basis should also fulfil the minimum requirements to calibrate neutron measuring devices. It is the primary purpose of this handbook to provide guidance on calibration of instruments for radiation protection. A calibration laboratory should also be in a position to calibrate instrumentation being used for the measurement of kerma and absorbed dose and their corresponding rates. This calibration is generally done with photons. In addition, since each neutron field is usually contaminated by photons produced in the source or by scatter in the surrounding media, neutron protection instrumentation has to be tested with respect to its intrinsic photon response. The laboratory will therefore need to possess equipment for photon calibration. This publication deals primarily with methods of applying radioactive neutron sources for calibration of instrumentation, and gives an indication of the space, manpower and facilities needed to fulfil the minimum requirements of a calibration laboratory for neutron work. It is intended to serve as a guide for centres about to start on neutron dosimetry standardization and calibration. 94 refs, 8 figs, 12 tabs

Accreditation: The US framework for colleges and professional disciplines

International Nuclear Information System (INIS)

Reyes-Guerra, D.R.

Accreditation is a system of verified quality control and recognition. When applied to education it becomes the instrument by which the quality of education is measure. For engineering, the recognized accrediting agency is the Accreditation board for Engineering and Technology (ABET). The American Nuclear Society (ANS) provides input to ABET and to the profession regarding the special educational needs of nuclear engineering or nuclear engineering technology and related fields. The accreditation process involves the determination of criteria applicable to the educational experience that will satisfy the profession and the individual discipline; the application, with judgment, of the criteria to an individual program; the visit to that program by an evaluation team; and the judgment of the program against the criteria. The accreditation process requires a comprehensive self-study of the specific program being evaluated. Results are verified on-site by the evaluation team. Programs are accredited for a limited time span: 6 yr at the maximum. Programs are reevaluated as necessary for continued accreditation

Efforts to combat the HIV/AIDS pandemic have underscored the fragile and neglected nature of some national health laboratories in Africa. In response, national and international partners and various governments have worked collaboratively over the last several years to build sustainable laboratory capacities within the continent. Key accomplishments reflecting this successful partnership include the establishment of the African-based World Health Organization Regional Office for Africa (WHO-AFRO) Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA); development of the Strengthening Laboratory Management Toward Accreditation (SLMTA) training programme; and launching of a Pan African-based institution, the African Society for Laboratory Medicine (ASLM). These platforms continue to serve as the foundations for national health laboratory infrastructure enhancement, capacity development and overall quality system improvement. Further targeted interventions should encourage countries to aim at integrated tiered referral networks, promote quality system improvement and accreditation, develop laboratory policies and strategic plans, enhance training and laboratory workforce development and a retention strategy, create career paths for laboratory professionals and establish public-private partnerships. Maintaining the gains and ensuring sustainability will require concerted action by all stakeholders with strong leadership and funding from African governments and from the African Union.

Experimental comparison between total calibration factors and components calibration factors of reference dosemeters used in secondary standard laboratory dosemeters

International Nuclear Information System (INIS)

Silva, T.A. da.

1981-06-01

A quantitative comparison of component calibration factors with the corresponding overall calibration factor was used to evaluate the adopted component calibration procedure in regard to parasitic elements. Judgement of significance is based upon the experimental uncertainty of a well established procedure for determination of the overall calibration factor. The experimental results obtained for different ionization chambers and different electrometers demonstrate that for one type of electrometer the parasitic elements have no influence on its sensitivity considering the experimental uncertainty of the calibration procedures. In this case the adopted procedure for determination of component calibration factors is considered to be equivalent to the procedure of determination of the overall calibration factor and thus might be used as a strong quality control measure in routine calibration.

Compare quality ratings of accredited and nonaccredited nursing homes using the publicly available Centers for Medicare and Medicaid Services (CMS) Nursing Home Compare data set. This cross-sectional study compared the performance of 711 Joint Commission-accredited (TJC-accredited) nursing homes (81 of which also had Post-Acute Care Certification) to 14,926 non-Joint Commission-accredited (non-TJC-accredited) facilities using the Nursing Home Compare data set (as downloaded on April 2015). Measures included the overall Five-Star Quality Rating and its 4 components (health inspection, quality measures, staffing, and RN staffing), the 18 Nursing Home Compare quality measures (5 short-stay measures, 13 long-stay measures), as well as inspection deficiencies, fines, and payment denials. t tests were used to assess differences in rates for TJC-accredited nursing homes versus non-TJC-accredited nursing homes for quality measures, ratings, and fine amounts. Analysis of variance models were used to determine differences in rates using Joint Commission accreditation status, nursing home size based on number of beds, and ownership type. An additional model with an interaction term using Joint Commission accreditation status and Joint Commission Post-Acute Care Certification status was used to determine differences in rates for Post-Acute Care Certified nursing homes. Binary variables (eg, deficiency type, fines, and payment denials) were evaluated using a logistic regression model with the same covariates. After controlling for the influences of facility size and ownership type, TJC-accredited nursing homes had significantly higher star ratings than non-TJC-accredited nursing homes on each of the star rating component subscales (P homes with Post-Acute Care Certification performed statistically better on the overall star rating, as well as 3 of the 4 subscales (P homes had statistically fewer deficiencies than non-TJC-accredited nursing homes (P payment denials (P homes

The rules of good laboratory practice have always been observed in the laboratories of National Institute of Hygiene (NIH) and the reliability of the results has been carefully cared after when performing tests for clients. In 2003 the laboratories performing analyses related to food safety were designated as the national reference laboratories. This, added to the necessity of compliance with work standards and requirements of EU legislation and to the need of confirmation of competence by an independent organisation, led to a decision to seek accreditation of Polish Centre of Accreditation (PCA). The following stages of building and implementation of management system were presented: training, modifications of Institute's organisational structure, elaboration of management system's documentation, renovation and refurbishment of laboratory facilities, implementation of measuring and test equipment's supervision, internal audits and management review. The importance of earlier experiences and achievements with regard to validation of analytical methods and guarding of the quality of the results through organisation and participation in proficiency tests was highlighted. Current status of accreditation of testing procedures used in NIH laboratories that perform analyses in the field of chemistry, microbiology, radiobiology and medical diagnostic tests was presented.

In this work, a new extended-length parallel-plate ionization chamber was tested in the standard radiation qualities for computed tomography established according to the half-value layers defined at the IEC 61267 standard, at the Calibration Laboratory of the Instituto de Pesquisas Energéticas e Nucleares (IPEN). The experimental characterization was made following the IEC 61674 standard recommendations. The experimental results obtained with the ionization chamber studied in this work were compared to those obtained with a commercial pencil ionization chamber, showing a good agreement. With the use of the PENELOPE Monte Carlo code, simulations were undertaken to evaluate the influence of the cables, insulator, PMMA body, collecting electrode, guard ring, screws, as well as different materials and geometrical arrangements, on the energy deposited on the ionization chamber sensitive volume. The maximum influence observed was 13.3% for the collecting electrode, and regarding the use of different materials and design, the substitutions showed that the original project presented the most suitable configuration. The experimental and simulated results obtained in this work show that this ionization chamber has appropriate characteristics to be used at calibration laboratories, for dosimetry in standard computed tomography and diagnostic radiology quality beams.
