Abstract
The mission of translational research involves difficult tasks to be accomplished for its ultimate goal, i.e., the introduction of novel, effective therapeutic strategies in the clinic to diminish human suffering and cure life-threatening diseases. Translational research (also referred to as translational medicine) facilitates the translation of investment in biomedical research into successful medical treatment. This includes the transfer of diagnostic and therapeutic advances by proving their efficacy in large evidence-based trials. Through the study of humans novel insights about disease are brought back to the laboratory to identify new, observation-based strategies. This "two-way road" ("bench to bedside and bedside to bench") process includes formulating guidelines for drug development and principles for new therapeutic strategies; initiating clinical investigations that provide the biological basis for new therapies, and related clinical trials; defining therapeutic targets and clinical endpoints. It requires a systematic approach beginning with specimen sampling, patient data collection, laboratory investigations, data analysis, preclinical testing, clinical trials, treatment efficacy monitoring, and finally the evaluation of therapeutic result. The marathon well symbolizes the enormous efforts undertaken by clinicians, scientists, regulators, ethicists, patient advocates, drug developers, and others, coordinately attempting to overcome obstacles along this road toward the final "marathon goal in medicine".

Abstract
Technologic innovations have substantially improved the productivity of clinical laboratories, but the services provided by clinical laboratories are increasingly becoming commoditized. We reflect on how current developments may affect the future of laboratory medicine and how to deal with these changes. We argue that to be prepared for the future, clinical laboratories should enhance efficiency and reduce costs by forming alliances and networks; consolidating, integrating, or outsourcing; and more importantly, create additional value by providing knowledge services related to in vitro diagnostics.

Abstract
Practicing clinical chemists responded to an anonymous, open-ended questionnaire designed to define the state of clinical chemistry education in pathology training programs in the United States. Survey respondents identified many ideas for educational improvements and offered criticism regarding aspects of clinical chemistry education that are not working particularly well. Many of these findings are generalizable to other subspecialties of clinical pathology. It is hoped that this analysis will allow readers to compare their programs with national trends and identify new ways of improving clinical chemistry training at their institutions.

Abstract
Abstract
Context.—Laboratory automation proposes to improve the quality and efficiency of laboratory operations, and may provide a solution to the quality demands and staff shortages faced by today's clinical laboratories. Several vendors offer automation systems in the United States, with both subtle and obvious differences. Arriving at a decision to automate, and the ensuing evaluation of available products, can be time-consuming and challenging. Although considerable discussion concerning the decision to automate has been published, relatively little attention has been paid to the process of evaluating and selecting automation systems.
Objective.—To outline a process for evaluating and selecting automation systems as a reference for laboratories contemplating laboratory automation.
Design.—Our Clinical Chemistry Laboratory staff recently evaluated all major laboratory automation systems in the United States, with their respective chemistry and immunochemistry analyzers. Our experience is described and organized according to the selection process, the important considerations in clinical chemistry automation, decisions and implementation, and we give conclusions pertaining to this experience.
Results.—Including the formation of a committee, workflow analysis, submitting a request for proposal, site visits, and making a final decision, the process of selecting chemistry automation took approximately 14 months. We outline important considerations in automation design, preanalytical processing, analyzer selection, postanalytical storage, and data management.
Conclusions.—Selecting clinical chemistry laboratory automation is a complex, time-consuming process. Laboratories considering laboratory automation may benefit from the concise overview and narrative and tabular suggestions provided.

Abstract
This article has been written to mark the 50th anniversary of the Canadian Society of Clinical Chemists (CSCC). It is not an exhaustive history of CSCC's activities but rather a review of many of the highlights that the Society and its members have experienced since its founding in October 1956. The names of many members who made important contributions to CSCC's development (but by no means all) are mentioned in the text. The historical material is presented by the decade but with blurred boundaries, as noteworthy advances in CSCC's history have most often developed gradually over several years and the terms of office of several CSCC Councils. From a founding roster of slightly over 70 members, the membership has grown to several hundred. The two main objectives for the Society's founding were stated by one of the three Montrealers who extended the original invitation, Dr. William S. Bauld: "to raise the standards of performance, and to raise the professional standing of clinical chemists". The early reports of committees on Instrumentation, Methods and Quality Control had rapid impact on individual members' laboratory practices across the country. The struggle for recognition of clinical chemists by other health professions inside and outside the clinical laboratories has taken much longer and has consisted of a long series of incremental successes through certification by examination, training programs, continuing education and, ultimately, the formation in 1986 of the Canadian Academy of Clinical Biochemistry. The CSCC's means of intra- and inter-communication with external organizations consist of its newsletter CSCC News, its scientific journal Clinical Biochemistry (established in 1967), and its more recently created website www.cscc.ca (1997). These three mechanisms ensure exchange of information between the officers of CSCC Council and the general membership and among members as well. National and international conferences have offered the newest scientific discoveries pertinent to the profession, exhibits featuring the latest in increasingly sophisticated instrumentation and reagents, and abundant opportunity to exchange information informally with old and newly met colleagues. By their contributions to the International Federation of Clinical Chemistry and the International Union of Pure and Applied Chemistry, CSCC members continue to play important roles far beyond Canada's borders.

Abstract
The basic technologies used in preanalytic processes for chemistry tests have been mature for a long time, and improvements in preanalytic processes have lagged behind improvements in analytic and postanalytic processes. We describe our successful efforts to improve chemistry test turnaround time from a central laboratory by improving preanalytic processes, using existing resources and the principles of lean production. Our goal is to report 80% of chemistry tests in less than 1 hour and to no longer recognize a distinction between expedited and routine testing. We used principles of lean production (the Toyota Production System) to redesign preanalytic processes. The redesigned preanalytic process has fewer steps and uses 1-piece flow to move blood samples through the accessioning, centrifugation, and aliquoting processes. Median preanalytic processing time was reduced from 29 to 19 minutes, and the laboratory met the goal of reporting 80% of chemistry results in less than 1 hour for 11 consecutive months.

Abstract
Within the United Kingdom, the job functions of the technologist are carried out by Biomedical Scientists who account for the greater proportion of staff employed within clinical laboratories. Their traditional responsibilities have involved providing a quality service through their scientific, technical and clinical skills. During the 1990s, a number of factors combined, leading to a change in the way which quality was viewed within the National Health Service (NHS). This has changed the role of the technologist, encouraging them to broaden their knowledge and take on new skills and responsibility.

Abstract
The aim of the study was to discover how an implemented quality system succeeded in fulfilling the personnel and management expectations and to identify the factors that facilitate or hinder quality management implementation in clinical laboratories. The concepts assessed include leadership (commitment and change management), clear and common goals, human recourses focus, client focus, management by fact and process improvement. The quality process in the laboratories had not, even after 3-4 years, reached a level of acceptance allowing its use as a daily development tool. The factors that predict a success of the quality system include willingness to improve the laboratory services and to keep the process going and good atmosphere at work. However, the study showed that the senior managers of the laboratory should take a more visible role in leading the change, and emphasize more explicitly the long-term goals. The middle managers (physicians, biochemists and head technologists) should arrange opportunities for the staff to participate in the system and disseminate the information on, and practical applications of, the quality principles and tools. The staff should be more active in finding new information and in participating in the system.

Abstract
One of the priorities of the European Confederation of Clinical Chemistry (EC4) is the harmonisation of the clinical laboratory profession in Europe. One of the first steps is to try to harmonise the quality systems, that is, the clinical laboratory organisational structure, responsibilities, procedures, processes and resources involved in quality management. The "EC4 Essential Criteria" were published by the Working Group on Harmonisation of Quality Systems in order to facilitate the development or the update of a quality system in a clinical laboratory, and to encourage international bodies to produce specific Standards for the clinical laboratory. Furthermore, the EC4 Working Group has produced a Quality Manual Model, which includes a sample of quality policy documents and some operational directions for an imaginary laboratory. This Quality Manual Model was prepared following the "EC4 Essential Criteria." Its purpose is that any quality system developed following the Manual could be accredited or certified against any Standard. The EC4 Quality Manual Model will be available, free of charge, to clinical laboratory professionals.

Abstract
Accreditation has been a successful approach to improved quality management in laboratories and applied to a wide variety of medical laboratories. After the initial enthusiastic phase, in which quality improvement is significant, the endurance is threatened by an increasing bureaucracy of the process. A productive balance between the accreditation bodies and the profession needs to be sought. New standards have been suggested by ISO and the profession needs to take the initiative to assure that a global standard specially adopted to the requirements of medical laboratories becomes recognised and used. The new concept of uncertainty may become an important tool to further improve and describe the performance of laboratories by allowing inclusion of pre- and post-analytical sources of uncertainty as well as bias.

Abstract
An International Standard, ISO 15189, specifically for 'Quality management in the medical laboratory' for use by accrediting 'bodies that recognize the competence of medical laboratories,' is expected to be published shortly. The origins, content and limitations of the new standard are discussed and the diversity of current arrangements for accreditation is reviewed. A new International Standard is an important step towards harmonization of laboratory practice but an accreditation system is more than its standards and a harmonized approach to the treatment of noncompliances found at inspection is important. Experience gained in writing national standards can improve the approach to the drafting and improvement of International Standards. Recognition of the principle of subsidiarity aids rather than hinders progress to harmonization and empowers the 'fourth element' (the laboratories to be accredited) to be a part of the accreditation process.

Abstract
Programs for Accreditation of clinical laboratories consider participation in External Quality Assessment Schemes (EQAS) a key element in the evaluation of testing procedures and improving them. One of the main functions of EQAS is to assess whether laboratories perform tests competently. It is therefore of utmost importance for laboratories to participate in EQAS that are in line with formally recognised requirements. Specific proposals have been made on how to design and execute EQAS by International Working Groups, but there seems to be no consensus on the best strategies to use and quality specifications to set out. The Clinical Pathology Accreditation (CPA) Program for EQA Scheme Accreditation (CPA-EQA) is the only program in Europe to provide a formal recognition of the quality of EQAS activities. The present paper reports on the experience of the Centre of Biomedical Research which is following an accreditation process for their own schemes in line with the CPA-EQA program and a proposal to set requirements that Italian schemes must follow to be recognised as valid and effective.

Abstract
Manufacturers of in vitro diagnostic (IVD) medical devices and laboratory management have become integral partners in building and improving the quality of laboratory services. There is an increasing awareness that quality is inherent in the design of any reagent or analytical system. In vitro diagnostic medical devices should provide patients, users and third parties with a high level of health protection. Therefore, both manufacturers and users must work in partnership for continual improvement. For manufacturers, standards such as ISO 9000 already exist to guide applications of quality practices. In the field of laboratory medicine, the availability of a specific, universal standard (ISO/DIS 15189) for quality management in medical laboratories will represent a great opportunity for harmonising medical laboratories at an international level. In addition, accreditation of medical laboratories according to the proposed ISO 15189 standard can help develop the relationships between laboratories, and the biological follow-up of travelling patients. Manufacturers are able to help laboratory management to reach a high level of quality, not only by providing high value products, but also on the basis of their own experience of ISO 9000 certification.

Abstract
Providing interpretative comments on reports, particularly those for primary care physicians is an important part of our job. Few clinical biochemists (whether medical or scientific) receive significant training for this. Most work in isolation, and few receive feedback on the utility of their comments. Surveys show an extremely wide divergence of opinion and comment even on apparently straightforward sets of abnormal results. Some comments are regarded as highly inappropriate when assessed by peer review. There is a need for further education and training in this area, concentrating as much on 'how to comment' as on 'what to comment'. There is also a need to establish some form of quality assurance for this important part of the post-analytical phase. A pilot External Quality Assurance Scheme (EQAS) is now being established.

Abstract
Successful practice of clinical pathology depends on a wide variety of laboratory, clinical, and managerial decisions. The skills needed to make these decisions can most effectively be learned by residents and fellows in pathology using a service-oriented on-call approach. We report our experience implementing an on-call system in the clinical chemistry laboratory at the University of Louisville Hospital (Ky). We detail the guidelines used to establish this system and the elements required for its successful implementation. The system emphasizes a laboratory-initiated approach to linking laboratory results to patient care. From inception of the program during late 1990 through 1995, the number of beeper calls (including clinician contacts) steadily increased and is currently 8 to 20 per week. The on-call system is active 24 hours per day, 7 days per week, thus representing activity on all three laboratory shifts. Types of responses were separated into administrative (12%), analytical (42%), clinical (63%), quality control or quality assurance (12%), and consultation (13%) categories. We also present 6 case reports as examples demonstrating multiple elements in these categories. In 23% of the calls, clinician contact was required and achieved by the fellow or resident on call for the laboratory. The on-call reports are documented and presented informally at weekly on-call report sessions. Emphasis is placed on learning and refinement of investigative skills needed to function as an effective laboratory director. Educational emphasis for the medical staff is in establishing awareness of the presence of the laboratory as an important interactive component of patient care. In addition, we found this program to be beneficial to the hospital and to the department of pathology in fulfilling its clinical service and teaching missions. Our experience may be helpful to other institutions establishing such a program.

Abstract
To ensure freedom of movement in the European Union, a limited number of professions is regulated by a so-called Sectorial Directive; all other disciplines, including clinical chemistry, fall under a General Directive. However, clinical chemists in the EU wish their specialty to be more specifically regulated; this means that common standards of education, training, experience and compliance with continuing professional developments must be guaranteed. Therefore, the European Communities Confederation of Clinical Chemistry (EC4) is about to implement the European Register for clinical chemists, and has composed a guide to this Register. The document describes the conditions for entry to specialty training, the minimum standards for registration (university education and postgraduate vocational training with a minimum total of eight years), the competencies of those qualifying for registration, and the operation of the register. Registration guarantees professional and managerial competencies; the title conferred is "European Clinical Chemist". EC4 recognises the existing national registers as far as they are based on the minimal requirements as indicated. An EC4 Register Commission (EC4RC) will maintain and control the European Register, supported by National Clinical Chemistry Registration Committees (NCCRC). An NCCRC controls the quality of the education in each country and assesses candidates. An individual (EU citizen or non-EU citizen trained in an EU country) applies privately for the European Register to EC4RC and, where applicable, the application is accompanied by a document from the NCCRC of the country of registration, stating that the applicant has the necessary qualifications. For EU citizens trained outside the EU the final decision is with EC4RC; non-EU citizens not trained in an EU country are not eligible for registration. Registration is renewed once every five years.

Abstract
The clinical laboratory is changing from a place of activity based on sample analysis to an in vitro diagnostic network. To convince our team, partners, and administrators, we need new comprehensive tools to define a strategy with limited risk of failure or conflicts. Specific quality goals should be established before choosing automated tools for sample handling, analytical systems, laboratory information systems, communication systems, or advanced technologies. A system approach maps and simplifies the process, based more on a functional study than on classical disciplines. A customer-supplier approach establishes the requirements between partners either inside or outside the laboratory. The quality system must be a management tool, linking samples, tasks, information, and documents. Quantitative simulation modeling explores different automation alternatives and their impact on laboratory workflow. Finally, integration of results in interactive semirealistic simulation tools for laboratory design or reengineering can be used as communications tools to involve laboratory professionals in the change of their practice.

Abstract
Laboratory work flow analysis was performed in order to define guidelines for improved laboratory organisation and efficiency. All activities were monitored from the moment a laboratory test was requested until the result was reported and received. Detailed information was collected on numbers of samples and tests, work-stations and sample splitting, number of staff and laboratory costs and management. From the data thus obtained requirements for optimal reorganisation could be developed. Reduction of work-stations appeared to be of primary importance. This could be achieved by replacement of seven different work stations by instruments for multi-functional analysis (Cobas Integra) in the department of routine clinical chemistry. Effects of reorganisation were evaluated by repeated work flow analysis. The multifunctionality of the analysers (photometry, turbidimetry, ion selective electrodes and fluorescence polarisation) provides opportunities for efficient work structuring, avoiding the need for sample splitting, distribution of sub-samples and performing analyses at different work stations. Manual and clerical errors could thus be reduced. Laboratory service to clinicians was improved by reduction of turnaround times to such an extent that all test results are reported within 60 minutes (stat service) even during peak hours. Laboratory costs were reduced by decreasing the number of laboratory staff and work-stations. Both clinicians and patients expressed great satisfaction with the effects of this reorganisation, for which work flow analysis appeared to be an indispensable instrument.

Abstract
The European Community Confederation of Clinical Chemistry (EC4) formed in Nice in April 1993 has established a working group on laboratory accreditation. The aim of the group is to explore the possibilities for harmonisation of accreditation and quality systems in clinical laboratories in the European Community (EC). It is felt essential that professions should play a key role in the process, and that the principle of subsidiarity should be observed in relation to implementation and organisation in individual member states. The first task has been to collect information concerning such systems. In September 1993 a questionnaire was distributed to the twelve IFCC related societies for clinical chemistry in the EC. By December 1994 eleven societies had responded. The questionnaire related to the existence or planned introduction of quality and accreditation systems, the basis of the standards used and requirements for analytical aspects and qualifications of staff as well as professional aspects. Questions also addressed the way in which inspection were organised, the selection and training of inspectors, the organisation of systems and what interest there was in harmonisation. The results of this study are presented in this paper.

Abstract
National quality award schemes can provide a detailed self-assessment process enabling an organization to assess its current position and to highlight opportunities for further improvement along the road to implementing best practice. This article describes how the Australian Quality Awards were used to guide the intermediate stages of implementation and to integrate some advanced stages of implementation of total quality management within a clinical chemistry department.

Abstract
The aim of the Working Group was to describe guidelines for deriving desirable analytical goals in laboratory medicine. First, a literature review is given of the different approaches used until now, and some of the most important studies are presented in detail. These approaches are then discussed critically, and the analytical goals proposed by the group are outlined with respect to monitoring and diagnostic testing. The group recommends that, most realistically, analytical quality specifications be biologically based. For diagnostic testing, the aim is achievement of accuracy, allowing the use of common reference intervals when populations are homogeneous for a given quantity. For monitoring (within an individual laboratory and performed with the same instrument), analytical performance should aim at stable operation and low imprecision compared with the within-subject biological variation. Method accuracy is also very important for the comparability of results from different laboratories or instruments.

Abstract
Analysis of eleven biochemical laboratory tests was done during an International External Quality Assessment Scheme (IEQAS) in which the clinical chemistry laboratory at Kenyatta National Hospital participated. Technicon SMA II continuous flow system was used in the biochemical analyses apart from glucose which was assayed manually by the glucose oxidase method. Using the standard deviation index (SDI), twenty six percent of the results were found to be outside the two standard deviation (2SD) limit. However, when variance index score (VIS) was used, 42% of the results were found to be outliers. Overall, our laboratory performed poorly compared to other laboratories in both the IEQAS and the United Kingdom External Quality Assurance Scheme (UKEQAS). This poor performance is attributed to the use of improper equipment which is not regularly maintained, lack of diagnostic reagents, lack of quality control (QC) materials and inadequate staff training in the field of quality control.

Abstract
The Dutch Foundation for Quality Assessment in Clinical Chemistry (SKZL) is the professional organization that conducts external quality-assessment schemes in The Netherlands. However, such schemes in fact assess the performance of the internal quality-control systems of the participating laboratories. In this paper we describe a new concept, relating the data for internal control materials with those for external samples and thereby leading to a combined external/internal scheme (Combi). The statistical principles underlying the Combi scheme are discussed and examples of the graphical presentation of the results are shown. Because the laboratory data are transmitted over the public telephone system to the computers of the SKZL, we also describe the principles of the data communication. At two-month intervals a statistical presentation is sent to all participants. The central database is updated daily with the received results, making possible an on-line consultation regarding the statistics of the accumulated findings of the control materials in use.
