Preanalytical phase is the most vulnerable part of the total testing process and is considered to be among the greatest challenges to the laboratory professionals. However, preanalytical activities, management of unsuitable specimens and reporting policies are not fully standardized, nor harmonized worldwide. Several standards related to blood sampling and sample transportation and handling are available, but compliance to those guidelines is low, especially outside the laboratory and if blood sampling is done without the direct supervision of the laboratory staff. Furthermore, for some most critical procedures within the preanalytical phase, internationally accepted guidelines and recommendations as well as related quality measures are unfortunately unavailable. There is large heterogeneity in the criteria for sample rejection, the different strategies by which unacceptable samples are managed, processed and test results reported worldwide. Management of unacceptable specimens warrants therefore immediate harmonization. Alongside the challenging and long road of patient safety, preanalytical phase offers room for improvement, and Editors at Biochemia Medica Journal definitely hope to continue providing a respective mean for reporting studies on different preanalytical phase topics. With pleasure and delight we invite potential future authors to submit their articles examining the quality of various preanalytical activities to Biochemia Medica. We will keep nurturing this topic as our prominent feature and by this we hope to be able to deliver valid evidence for some future guidelines and recommendations. 相似文献

The Eigenfactor score is a journal influence metric developed at the Department of Biology of the University of Washington and recently introduced in the Science and Social Science Journal Citation Reports maintained by Thomson Reuters. It provides a compelling measure of journal status with solid mathematical background, sound axiomatic foundation, intriguing stochastic interpretation, and many interesting relationships to other ranking measures. In this short contribution, we give 10 reasons to motivate the use of the Eigenfactor method. 相似文献

Journal self-citation study for semiconductor literature: Synchronous and diachronous approach 总被引：1，自引：0，他引：1
The present study investigates the self-citations of the most productive semiconductor journals by synchronous (self-citing rate) and diachronous (self-cited rate) approaches. Journal’s productivity of 100 most productive semiconductor journals was gathered from INSPEC database, 1978–1997 through OVID. Data of citation frequency were obtained from the Science Citation Index (SCI), Journal Citation Reports (JCR) 2001 CDROM edition by the title-by-title search. The self-citing and self-cited data were drawn from the Citing Journal Listing and the Cited Journal Listing of the JCR CDROM version 1990–2001. Self-citing and self-cited rates were determined by the method suggested by the JCR. Eighty-seven journals common to INSPEC and JCR in semiconductor were selected as the object of this study and were listed for statistical tests. The results of the present study demonstrate that high self-citing journals are usually older than low self-citing journals. In contrast to the self-citing data, the journal self-cited rate is not closely related to the publication year but reflects the characteristics of various journals. Journals with a short time interval of publication are more possible with high self-citing and self-cited rates. Journals with higher self-citing rate tend to be more productive and receive more citation than journals with lower self-citing rate. The journal self-cited rate has no association with the number of articles that a journal published and the citation it received. A journal with a higher self-citing rate tends to be cited more by itself. The mean self-citing rate is 9.59% and the mean self-cited rate is 15.03%. There is a significant difference between self-citing and self-cited rates within the same set of journals. 相似文献
