Quality systems can provide a means of measuring the rate of occurrence of defined incidents and non-conformities. We have
studied the application of laboratory quality systems to monitoring the implementation of laboratory information systems (LIS)
in two similar size tertiary hospital pathology laboratories in Australia. At one site, one department implemented a quality
system accredited to ISO 9001–1987 and ISO 9001–1994 while the rest of the organisation did not have a formal quality system;
this site implemented the Cerner PathNet LIS. At the other site, the organisation was in the process of implementing ISO/IEC
Guide 25–1990 and ISO/IEC 17025–1999; this site implemented the PJACC AUSLAB LIS. The rate of quality system incidents and
non-conformities was used to track the progress of implementation of the LIS. We found that different quality systems appeared
equally useful in monitoring the rate of occurrence of incidents. However, the presence of a formal quality system greatly
improved the proportion of incidents that could be investigated and resolved at root cause level. Incident monitoring, as
part of a formal quality system, proved to be a useful tool in monitoring and managing the implementation of these LIS.

ISO 11843 part 7 (ISO 11843-7) can provide a standard deviation (SD) of area measurements of a target peak through the stochastic behaviors of instrumental noises. The purpose of this study is to demonstrate that ISO 11843-7 can be applied to assess repeatability in an isocratic liquid chromatography–tandem mass spectrometry (LC–MS/MS) system without repetitive measurements. The relative standard deviation (RSD) of the peak area of ergosterol picolinyl ester, which was used as an example, on a multiple reaction monitoring (MRM) chromatogram was determined by ISO 11843-7. The RSD by ISO 11843-7 (N = 1) was within a 95% confidence band of the RSD by repetitive measurements (N = 6). Moreover, the effects of digital smoothing, such as moving average, were also examined on the repeatability assessment in LC–MS/MS by ISO 11843-7. From the results of the comparisons of the RSDs obtained by ISO 11843-7 and the repetitive measurements, it was shown that suitable RSDs of the peak area were obtained from the smoothed MRM chromatograms by the moving average for narrow data point windows (e.g., one-sixth of the peak width). In conclusion, the utility of repeatability assessment based on ISO 11843-7 has been expanded for the validation of an LC–MS/MS system. 相似文献

Management review of the quality-management system is an item in many quality standards and a requirement of the ISO 9001:2000
standard and of laboratory standards ISO 15189 and ISO 17125, and others. These reviews are conducted to ensure that the top
management is informed and involved in the quality-management system with respect to continuing adequacy and effectiveness,
and opportunities for improvement of the system. The management review is a process that should be conducted and audited utilizing
the process approach. A process approach is defined as “An activity using resources and managed in order to enable the transformation
of inputs into outputs” (ISO 9001:2000). All identified main processes in the quality system should be monitored through data
collection by appropriate methods, assuring that data are valid, representative, and adequate. For management review data
must be collected and presented in an accessible form so that processes can be evaluated according to objectives, goals, resources,
etc. On the basis of this information the laboratory management makes the necessary decisions and ensure that actions are
taken that improve the effectiveness of the quality-management system. As output from the management review process, there
should be evidence of decisions regarding: change of quality policy and objectives; plans and possible actions for improvements;
corrective actions as appropriate; increased customer satisfaction; and planning of resources needs. Identification of the
processes involved and using the process approach in the management review ensures the continual improvement of the quality
system.

As a laboratory certified to ISO 9001:2000 and accredited to ISO 17025, rtech laboratories has incorporated an overall system for technical and quality management, which results in benefits observed in daily laboratory practices. Technical requirements were updated to include the addition of formal personnel training plans and detailed records, method development and validation procedures, measurement of method uncertainty, and a defined equipment calibration and maintenance program. In addition, a stronger definition of the sample preparation process was documented to maintain consistency in sampling, and a more rigorous quality control monitoring program was implemented for chemistry and microbiology. Management quality improvements focused on document control to maintain consistent analytical processes, improved monitoring of supplier performance, a contract review process for documenting customer requirements, and a system for handling customer comments and complaints, with continuous improvement through corrective and preventive action procedures and audits. Quarterly management review of corrective actions, nonconforming testing, and proficiency testing aid in determining long-term trending. The practical benefits of these technical and management quality improvements are seen on a daily basis in the laboratory. Faster identification and resolution of issues regarding methods, personnel or equipment, improved customer satisfaction, meeting quality requirements of specialized customers, and overall increased laboratory business are all the result of implementing an effective quality system. 相似文献

The production of pharmaceuticals is one of the most highly regulated fields in terms of quality. The body of good manufacturing practice (GMP) represents the standard required by law; GMP embraces the guidelines that regulate all activities related to the production and quality control of medicinal products for human and veterinary use. This paper deals with the implementation of a quality management system (QMS) in compliance with GMP and ISO 9001 standards for the production and distribution of radiopharmaceuticals in a public research institute. The production of 2-[18F]fluoro-2-deoxy-d-glucose has been implemented according to GMP standards and has been licensed by the national Authority in 2007. In 2010, a project to orient the system??s GMP compliance to ISO 9001 standards has been approved. A QMS conforming to ISO 9001:2008 should be considered an important additional step in terms of quality, because ISO 9001 also takes into account economic and financial aspects, design and development aspects and introduces management review for measurement and analysis of the process with the aim of improving performances. The harmonization between GMP and ISO has been defined following the Pharmaceutical Quality System Q10 guideline developed by International Conference on Harmonization. 相似文献

In 1995, the Council of Europe published a guide with recommendations providing transfusion services with a set of guidelines and principles relating to the preparation, use and quality assurance of blood components. As a blood transfusion service is at the same time a supplier of blood products and a test laboratory the quality management system must include good medical practice, good manufacturing practice and good laboratory service, all of which are closely linked. We made a critical evaluation of the content of the guide and analysed requirements and recommendations in comparison with quality management systems applied by the concerned partners. As a major critic we observed that the guide does not take into account any quality system of the in vitro diagnostic (IVD) supplier and/or distributor. With the addition of some items outlined in ISO 25 and ISO 9000, the Council of Europe document can be improved so that it complies with internationally accepted quality management standard recommendations. 相似文献

If we agree that quality assurance (QA) in R&;D indeed provides added value, just how do we show the public that such a QA system is operating well? At the Belgian Nuclear Research Centre (SCKÖbullet CEN), where a QA system has been implemented by various laboratories in accordance with the EN 45001 standard within the general framework of ISO 9001 at the institutional level, several laboratories have already been accredited. At the request of one of our customers the Belgian Agency for Radioactive Waste Management (NIRAS/ONDRAF), we implemented a quality system for research projects related to the characterization, treatment and processing of radioactive wastes in view of disposal. We obtained accreditation for this research in 1999. In this paper, we discuss the implementation of our QS and important issues related to the overall management of the QA system, broken down into three parts: organizational, technical and project-specific quality elements such as the QA plan and internal communication. 相似文献
