The implementation of a preanalytical quality monitoring system based on observation of evidence-based QIs and patient-centered evaluation of errors through risk analysis with regular tailored education as well as implementing process improvements can effectively reduce preanalytical errors in the emergency laboratory and improve patient safety.
provide useful information about the state of health of patients, determination of reference value is considered an intrinsic part in the development of laboratory medi cine. There are still huge differences in the analytical methods used as well as in the associated reference intervals which could consequently significantly affect the proper assessment of patient health. In a constant effort to increase the quality of patients' care, there are numerous international initiatives for standardiza tion and/or harmonization of laboratory diagnostics in order to achieve maximum comparability of laboratory test results and improve patient safety. Through the standardization and harmonization processes of analytical methods the ability to create unique reference intervals is achieved. Such reference intervals could be applied globally in all laboratories using methods traceable to the same reference measuring system and analysing the biological samples from the populations with similar sociodemographic and ethnic characteristics. In this review we outlined the results of the harmonization processes in Croatia in the field of population based reference intervals for clinically relevant blood and serum constituents which are in accordance with ongoing activity for worldwide standardization and harmonization based on traceability in laboratory medicine.

Introduction: The aim of the study was to present a protocol for laboratory information system (LIS) and hospital information system (HIS) validation at the Institute of Clinical Chemistry and Laboratory Medicine of the Merkur University Hospital, Zagreb, Croatia. Materials and methods: Validity of data traceability was checked by entering all test requests for virtual patient into HIS/LIS and printing corresponding barcoded labels that provided laboratory analyzers with the information on requested tests. The original printouts of the test results from laboratory analyzer(s) were compared with the data obtained from LIS and entered into the provided template. Transfer of data from LIS to HIS was examined by requesting all tests in HIS and creating real data in a fi nding generated in LIS. Data obtained from LIS and HIS were entered into a corresponding template. The main outcome measure was the accuracy of transfer obtained from laboratory analyzers and results transferred from LIS and HIS expressed as percentage (%). Results:The accuracy of data transfer from laboratory analyzers to LIS was 99.5% and of that from LIS to HIS 100%. Conclusion: We presented our established validation protocol for laboratory information system and demonstrated that a system meets its intended purpose.

Laboratory results infl uence 70% of medical diagnoses (1). The quality of laboratory service is the major factor that directly aff ects the quality of health care (2). Accreditation according to an internationally recognized standard such as ISO 15189 "Medical laboratories -Particular requirements for quality and competence" is a recognition of a laboratory's competence and compliance with the requirements of the standard (3). It is acknowledged as the single most eff ective route to comprehensive quality assurance (4).Improving quality of the work process is one of the main goals of accredited laboratories, and development of a laboratory information system is a precondition for quality improvement in this phase of laboratory process (5,6). software be addressed in the same way as the instruments (9). One of the newest accreditation requirements includes recommendations for the protection of LIS -Annex B. Amongst numerous demands, the laboratory management must ensure maximum security of data entry and reports (B5.) (10). To respond to the particular requirement of the accreditation standard for medical laboratories, the accuracy of the entire process of data transfer between laboratory equipment and laboratory (LIS) and hospital information (HIS) systems needs to be validated and appropriately documented.The aim of this study was to esta...
