Introduction
Hemolysis can occur during sample collection, handling and transport. It is more frequent when the non-laboratory staff performs sampling. The aim of this study was to assess nurses’ knowledge on the causes of hemolysis and consequential impact on the laboratory tests results. Additionally, the differences in knowledge, related to work experience, professional degree and previous education about hemolysis were explored.Materials and methods
An anonymus survey, containing 11 questions on demographics, causes of hemolysis, its impact on biochemical parameters and nurses’ attitude towards additional education in preanalytics, was conducted in four Croatian hospitals. The answers were compared by Chi-squared and Fischer exact test.Results
In total, 562 survey results were collected. Majority of nurses declared familiarity with the term “hemolysis” (99.6%). There were 77% of correct answers regarding questions about the causes of hemolysis, but only 50% when it comes to questions about interference in biochemical tests. The percentage of correct answers about causes was significantly lower (P = 0.029) among more experienced nurses, and higher (P = 0.027) in those with higher professional degree, while influence of previous education was not significant. Also, higher percentage of correct answers about interferences was encountered in nurses with longer work experience (P = 0.039). More than 70% of nurses declared that additional education about preanalytical factors would be beneficial.Conclusion
Croatian nurses are familiar with the definition of hemolysis, but a lack of knowledge about causes and influence on laboratory test results is evident. Nurses are eager to improve their knowledge in this field of preanalytical phase.Key words: hemolysis, nurses, survey, preanalytical phase 相似文献2.

Introduction:
Alpha-1-antitrypsin deficiency (AATD), genetic risk factor for premature chronic obstructive pulmonary disease (COPD), often remains undetected. The aim of our study was to analyse the effectiveness of an integrative laboratory algorithm for AATD detection in patients diagnosed with COPD by the age of 45 years, in comparison with the screening approach based on AAT concentration measurement alone.Subjects and methods:
50 unrelated patients (28 males/22 females, age 52 (24–75 years) diagnosed with COPD before the age of 45 years were enrolled. Immunonephelometric assay for alpha-1-antitrypsin (AAT) and PCR-reverse hybridization for Z and S allele were first-line, and isoelectric focusing and DNA sequencing (ABI Prism BigDye) were reflex tests.Results:
AATD associated genotypes were detected in 7 patients (5 ZZ, 1 ZMmalton, 1 ZQ0amersfoort), 10 were heterozygous carriers (8 MZ and 2 MS genotypes) and 33 were without AATD (MM genotype). Carriers and patients without AATD had comparable AAT concentrations (P = 0.125). In majority of participants (48) first line tests were sufficient to analyze AATD presence. In two remaining cases reflex tests identified rare alleles, Mmalton and Q0amersfoort, the later one being reported for the first time in Serbian population. Detection rate did not differ between algorithm and screening both for AATD (P = 0.500) and carriers (P = 0.063).Conclusion:
There is a high prevalence of AATD affected subjects and carriers in a group of patients with premature COPD. The use of integrative laboratory algorithm does not improve the effectiveness of AATD detection in comparison with the screening based on AAT concentration alone. 相似文献3.

Introduction:
Continuing professional development (CPD) with corresponding crediting system is recognized as essential for the laboratory medicine specialists to provide optimal service for the patients. Article presents results of the survey evaluating current CPD crediting practice among members of European Federation of Clinical Chemistry and Laboratory Medicine (EFLM).Materials and methods:
A questionnaire had been forwarded to presidents/national representatives of all EFLM members, with invitation to provide information about CPD programmes and crediting policies, as well as feedback on individual CPD categories, through scoring their relevance.Results:
Complete or partial answers were received from 28 of 38 members. In 23 countries, CPD programmes exist and earn credits, with 19 of them offering access to non-medical scientists. CPD activities are evaluated in all participating countries, regardless to the existence of an official CPD programme. Among participating members with mandatory specialists’ licensing (22/28), CPD is a prerequisite for relicensing in 13 countries. Main categories recognized as CPD are: continuing education (24 countries), article/book (17/14 countries) authorship and distance learning (14 countries). The highest median score of relevance (20) is allocated to professional training, editor/authorship and official activities in professional organizations, with the first category showing the least variation among scores.Conclusions:
Majority of EFLM members have developed CPD programmes, regularly evaluated and accompanied by crediting systems. Programmes differ in accessibility for non-medical scientists and impact on relicensing eligibility. Continuing education, authorship and e-learning are mainly recognized as CPD activities, although the professional training is appreciated as the most important individual CPD category. 相似文献
