To establish a national accreditation system for medical laboratories, Iran has set national standards based on the international standard ISO 15189. Central to the accreditation process are the technical assessors. Their attitude in this regard and their experiences should be identified. This study aims to explore assessors’ attitudes toward national laboratory accreditation and their experiences of assessment process in order to identify current gaps and suggest required interventions to solve them. A qualitative study using an open-ended questionnaire was employed. A total of 150 assessors working in the General Directorate of Laboratory Affairs participated in the study. While almost all Iranian laboratory accreditation assessors were generally supportive about the necessity of laboratory accreditation and cited benefits of this process, they pointed to improvement areas including developing assessor selection and appraisal criteria, continuous training, taking into consideration the heterogeneity of laboratories throughout the country, participation of professional associations and adopting measures to increase laboratories’ involvement. 相似文献

Accreditation of healthcare services is recommended to ensure operation according to the highest quality standards. Various initiatives, such as legislation or accreditation by ISO or JCI, may be active to support and improve quality. The growing trend toward JCI hospital accreditation raised the concern of redundancy between JCI requirements for the use of referral laboratories and the ISO 15189 accreditation for medical laboratories. This would result in needless administrative efforts for hospital laboratories to collect and maintain required documentation, as the JCI quality requirements would be guaranteed given that the referral laboratory is ISO 15189 accredited for those examinations. A consensus meeting was organized by the Working Group for Hospital Accreditation of the Belgian Zorgnet-Icuro network, the University Hospitals of Leuven and the Red Cross to discuss the avoidance of any redundancy between both standards and to issue best practice guidelines for referral laboratories. It was concluded that JCI measurable elements for referral laboratories are covered by the ISO 15189 accreditation scope. The article substantiates the consensus that JCI and ISO quality requirements are harmonized and that accurate knowledge and interpretation of prevailing quality standards are essential to avoid redundancy in quality measures. 相似文献

A new ISO standard (ISO/DIS 15189) on quality management in the medical laboratory is being prepared. The origins and development of this in ISO and the interaction by CEN in Europe is presented. The major comments already received are given as well as the likely progress of this ISO standard. Once published it will have implications for accreditation of medical laboratories throughout the world and particularly those in Europe. 相似文献

High-quality and reliable laboratory services are important components of effective and well-functioning health systems. Accurate, reliable and timely medical laboratory testing is crucial to patient care and disease surveillance. Unfortunately, in many sub-Saharan African countries, medical laboratory systems are adversely affected by the unavailability of medical laboratories, poor laboratory infrastructure and lack of well-trained personnel [1]. Quality in the laboratory is only achieved in a systematic way through the implementation of a quality management system. The results of the study showed that approximately 60?% of the 78 respondents were unaware of the requirements of ISO 15189:2007. A trial of proficiency testing, termed ??blind proficiency testing??, was carried out in which 19 laboratories determined the concentrations of urea and cholesterol in a proficiency testing material. Of the 19 laboratories that determined the concentration of urea, 63?% produced satisfactory results with scores between ?2 and +2. Similarly, 63?% of the participating laboratories obtained satisfactory z scores for cholesterol determination. Some of the laboratories that obtained satisfactory scores for urea determination had unsatisfactory scores for cholesterol determination and vice versa. It is recommended that the Ghanaian government pass a law and establish a standard to regulate medical laboratories in Ghana in order to improve quality in a significant way. 相似文献

The Department of Public Health Laboratories consists of five major laboratories located across the country of Israel: four
environmental laboratories performing microbiological and chemical testing of food and water products [accredited according
to International Organization for Standardization (ISO) 17025 since 1999) and a fifth laboratory that is dedicated to virology
testing (certified according to ISO 9000 since 2003). Historically, each laboratory operated independently and developed its
own quality assurance (QA). On November 2004, an important strategic decision was made: to unify all five laboratories’ QA
systems conformed to ISO 17025, ISO 15189, and ISO 9000—a transition from five laboratories operating independently in the
field of QA toward establishing a multisite laboratory. This process was considered and visualized as a major organizational
change and therefore raised some resistance among both QA managers and the professional laboratories’ management. Thus, it
was necessary to overcome the resistance and at the same time induce thoughts of ways of reshaping and formatting the new
and uniform quality manual and uniform standard operating procedures (SOPs). In September 2005, the first phase of the process
was completed, and all four environmental public health laboratories successfully passed a reaccreditation audit using a uniform
QA manual guide and partially uniform SOPs. We shall share our experience and discuss the major contributions of this process
to overall laboratory management.

Guidelines ISO 17025 and ISO 15189 aim to improve the quality-assurance scheme of laboratories. Reliable analytical results are of central importance due to the critical decisions that are taken with them. ISO 17025 and ISO 15189 therefore require that analytical methods be validated and that laboratories can routinely provide the measurement uncertainty of the results of measurements. To evaluate the fitness of purpose of analytical methods, total error is increasingly applied to assess the reliability of results generated by analytical methods. However, the ISO requirement to estimate measurement uncertainty seems opposed to the concept of total error, leading to delays in laboratories implementing ISO 17025 and ISO 15189 and confusion for the analysts. This article therefore aims to clarify the divergences between total error and measurement uncertainty, but also to discuss their main similarities and emphasize their implementation. 相似文献

ISO/IEC 17025:2005 states that its requirements are “applicable to all laboratories regardless of the number of personnel” and would therefore include single-operator laboratories. However, there are reservations as to whether these laboratories can comply with all of the requirements without jeopardizing independence of judgement and impartiality. Similarly, there are some requirements of ISO/IEC 17025:2005 including staff supervision, internal communication processes and appointment of deputies that are considered unlikely to apply to a single-operator laboratory. The ISO/IEC 17025:2005 is widely used as the international standard of quality assurance by which accreditation bodies assess the competency of testing and calibration laboratories. There does, however, appear to exist, disagreement amongst accreditation experts when considering single-operator laboratories. Some accreditation bodies accredit single-operator laboratories, whilst others require additional human resources prior to granting accreditation. This discrepancy leads to unfair competition amongst laboratories as a single-operator laboratory by definition needs less resources (both human and financial) to achieve and maintain accreditation, compared with a laboratory where additional human resources need to be sought prior to and in order to maintain accreditation. The ISO/IEC 17025:2005 is in the process of being revised, and this is an opportune moment to address the issues aforementioned with the aim of removing ambiguity and enhancing clarity. In addition, the hope is to assist the accreditation bodies themselves to adopt a consensus approach when granting accreditation towards single-operator laboratories. 相似文献

The Finnish Accreditation Service (FINAS) accredits testing laboratories in all fields including medical laboratories according
to European standard EN 45001 and ISO Guide 25. At the beginning of 1998, FINAS published a recommendation on how to apply
general standards in histo- and cytopathology. Four pathology laboratories have been accredited to date. FINAS has not included
autopsies in these accreditations. The International Academy of Pathology (IAP)-Finnish Division has recognized 21 pathology
laboratories according to standards of their own. Although accreditation by FINAS is not connected to the system of the IAP-Finnish
Division, the requirements are very similar in both. Less than half of the pathology laboratories in Finland participate in
national quality improvement programme or have been accredited by FINAS. 相似文献

Increasing demands from health care planners and industrialists conducting clinical trials, as well as general competition,
are forcing medical laboratories to seek third-party recognition of their quality management systems. There is a tendency
to move from certification of a laboratory director, via certification of the laboratory quality system (ISO 9000 family),
to accreditation needing proof of professional and technical competence in laboratory tasks. The requirements of accreditation
are presented in several national schemes and in the European Standards series (EN 45 000) and the International Organization
for Standardization's guide, ISO/IEC 25, to be amalgamated soon. The latter system provides transnational recognition through
participation of the accrediting bodies in the European co-operation for Accreditation. Necessary supplementary guidelines
exist for chemical laboratories (Eurachem) and medical laboratories CEAC/ECLM). Traceability and reliability of results are
obtained by utilizing a global reference examination system and by participating in transdisciplinary work. The costs of achieving
accreditation are considerable and mainly involve the production of quality handbooks and written work procedures by personnel.
The rewards are an open system, smoother work, emphasis on prevention of mistakes, and satisfied stakeholders.

The Catalan Association of Clinical Laboratory Sciences, with the support of its corporative members, organized the second European symposium devoted to physiological reference values, in Barcelona. The objectives were: (i) to discuss ways to develop a common strategy among clinical laboratories and the in vitro diagnostic (IVD) industry for the generation of physiological reference values related to biological quantities of medical interest; and (ii) to establish consensus between both groups regarding the interpretation of the requirements related to physiological reference values contained in the European (EU) Directive 98/79-EC and in the EN-ISO 15189:2003 standard. The symposium was divided into four parts in which different aspects of the reference values were discussed: legal and normative aspects, alternatives to the production of own reference values, methodology, and diffusion and teaching. The main conclusions were the need to clarify the requirements described by the EU Directive 98/79-EC and EN-ISO 15189:2003 regarding reference values, and the need for cooperation between industry, clinical laboratories, and health authorities to achieve common reference intervals, including multicentric reference intervals. 相似文献

This article presents an overview of the practical experience acquired in two governmental medicines control laboratories
in the Netherlands which combine the application of EN 45001 and ISO 9002 standards in the regulatory field of quality and
risk assessment, and quality control of medicines and medical devices. This practical experience also includes simultaneous
accreditation and certification. The EN 45001 standard was applied to laboratory testing activities and the ISO 9002 standard
to non-laboratory file assessment activities as these activities are not covered by the scope of EN 45001. It appears that
a combined application of these standards is practicable because they complement each other well. EN 45001 strongly emphasises
technical competence. ISO 9002, on the contrary, emphasises more strongly the efficiency of the management processes and customer
requirements.

Management reviews are key processes in many quality-management systems, including laboratory-management systems, in accordance
with ISO/IEC 17025 and ISO 15189. These reviews are fine opportunities to understand and manage all the inputs and outputs
of a quality-management system. Laboratories often meet some difficulties fully exploiting the management-review process because
either they do not realize the importance of this process or they do not have the experience to run this process in a way
producing the intended results. This work presents a management review checklist which helps laboratories carry out an effective
management review going through all the important aspects of the quality-management system. 相似文献

The Department of Clinical Chemistry and Molecular Genetics, within the Institute of Clinical Pathology and Medical Research
at Westmead Hospital, is a medical testing laboratory operating within the public sector health system of New South Wales,
Australia. It provides acute-care pathology services to Westmead Hospital (a 900-bed tertiary referral university teaching
hospital) as well as to three district hospitals and three rural hospitals. In addition to these core clinical chemistry services,
it offers approximately 150 specialised biochemistry, pharmacology, toxicology, trace metal and molecular genetics assays
as a reference laboratory service. In 1993, the Department became Australia's first medical testing laboratory to be registered
to ISO 9001-1987/AS3901-1987. In 1995, this certification was extended to AS/NZS ISO 9001-1994. We are currently preparing
for further accreditation to ISO/IEC Guide 25-1990, with additional supplementary requirements for medical testing. This paper
describes the Quality System that the Department developed and which has been successfully maintained and extended since original
certification. Important features of the Quality System are:
1. Primary design of the Quality System to meet medical and customer needs, with subsequent addition of required ISO elements.
2. Use of national Quality Award criteria to identify key business processes.
3. Development of integrated technical non-conformance, customer complaint, staff suggestion, and quality system corrective
action procedures.
4. Implementation without external resources.
Our conclusions are that ISO 9000 Quality Systems can be applied to medical testing laboratories, and can be implemented with
minimum resource costs. Improvements in technical and service quality and business performance have resulted from this process.
However, implementation of ISO 9000 at the level of individual Departments is not ideal. Greater improvements are possible
when this process is undertaken at the level of the entire organisation.

ISO/IEC guide 25 is the internationally recognised base document for the accreditation of laboratories. Laboratory accreditation
is a system of peer assessment and a formal recognition that a laboratory is competent to perform specific tests or types
of tests ISO/IEC guide 25 plays a fundamental role in the life of the analytical chemist and is pivotal to the acceptance
of the philosophy "once tested everywhere accepted" and to ensuring the mutual acceptance of test data. Within the EU, the
attainment of accreditation to ISO/IEC guide 25 has become a way of life and it is now mandatory for laboratories engaged
in certain regulatory work areas. Guide 25 is currently under revision and over the past 2 years or so it has been the subject
of much debate among the calibration and testing community and it has engendered a considerable amount of written and oral
comments. The latest revision entitled "Draft International Standard ISO/IEC DIS 17025: General Requirements for the Competence
of Testing and Calibration Laboratories" was circulated to national standard organisations for their "comment and approval"
in mid 1998. Voting on this document commenced on 9 July and terminates on 9 December 1998. It is anticipated that a final
draft could be circulated in 1999. In accordance with the Vienna agreement this is a parallel ISO/CEN enquiry. This paper
will discuss the implications of the technical requirements of the current document for analytical chemistry with particular
emphasis on, the strengths, weaknesses and deficits inherent in the draft circulated in July 1998. 相似文献
