Indagine conoscitiva congiunta SIBioC-Medicina di Laboratorio e Associazione Italiana Pneumologi Ospedalieri (AIPO) relativa alla gestione del processo diagnostico del liquido pleurico
Results of a survey produced by the Italian Society of Clinical Biochemestry (SIBioC) and the Italian Association of Hospital Pneumologists (AIPO) concerning pleural fluid analysis
<p>The aim of this paper is to present the preliminary results of a joint project by SIBioC-AIPO working group on &ldquo;Body cavities fluids&rdquo;. The main purpose of the working group is to achieve a harmonized and shared diagnostic pathway related to pleural fluid (PF) analysis. The multistep project begins with a state of the art analysis. A survey, sent to both laboratory medicine personnel and pneumologists, was conducted between October and December 2016. The questionnaire (21 questions) was made available through the web-based SurveyMonkey platform. Overall, 408 replies were collected, 40.4% from laboratory medicine specialists, 3.2% from laboratory technicians, 49.3% from pneumologists and 7.1% from professionals with non-specified qualification. Regarding the pre-analytical phase, the most critical issue resulted to be the clinical query, due to the lack of structured communication between clinicians and laboratory personnel. While over 76% of laboratory professionals stated that the working diagnosis was unavailable, 87% of pneumologists affirmed that the clinical question had been forwarded to the laboratory. An important issue was the widespread use of inappropriate containers for PF collection (60% of inappropriate tubes). Regarding the panel of tests, a satisfactory agreement was reached on the need to perform macroscopic analysis and cytometric evaluation, along with the assessment of pH, glucose, total proteins, lactate dehydrogenase and the respective ratios between PF and serum concentrations. As expected, the availability of verified or validated analytical methods, notably pH analysis, has emerged as a critical point. The layout of the laboratory report also needs improvements and better harmonization. Despite the many critical issues emerged from this survey, a positive feedback was reflected by a notable general interest on PF analysis, leading thus the way to produce a joint consensus document involving clinicians and laboratory personnel, as suggested by more than 30% of responders.</p>

La fase pre-analitica dei campioni provenienti dal Pronto Soccorso: impatto della introduzione di un impianto di posta pneumatica nel miglioramento del tempo di risposta
Improving pre-analytical laboratory turnaround time for the emergency department: outcomes of a pneumatic tube system introduction
<p>Background: the pre-analytical phase of the stat tests requested by the Emergency Department (ED) has been rarelystudied in relation to the containment of the laboratory turnaround time (TAT).<br />Methods: through a pre-analytical workflow analysis in a large ED with &quot;Lean&quot; methodology, some improvementshave been activated, including the installation of a pneumatic tube system (PTS).<br />Results: significant improvement of TATs (23 minutes at 90th percentile) and also of length of stay (LOS) of EDpatients (53 minutes at 90th percentile) has been documented. The plasma concentrations of a number of analytesmeasured in samples transported manually and by PTS were very similar (lactic dehydrogenase excluded),demonstrating that PTS does not alter the integrity of the samples.<br />Conclusions: compared to manual transportation, the use of this PTS significantly reduced transport time and alsoimproved some pre-analytical flow phases within the ED. The system is suitable for the measurement of most of theanalytes commonly requested for ED patients.</p>

Raccomandazione congiunta EFLM-COLABIOCLI per il prelievo di sangue venoso
Joint EFLM-COLABIOCLI Recommendation for venous blood sampling
<p>This document provides a joint recommendation for venous blood sampling of the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) Working Group for Preanalytical Phase (WG-PRE) and Latin American Working Group for Preanalytical Phase (WG-PRE-LATAM) of the Latin America Confederation of Clinical Biochemistry (COLABIOCLI). It offers guidance on the requirements for ensuring that blood collection is a safe and patient-centered procedure and provides practical guidance on how to successfully overcome potential barriers and obstacles to its widespread implementation. The target audience for this recommendation are healthcare staff&nbsp;members directly involved in blood collection. This recommendation applies to the use of a closed blood collection system and does not provide guidance for the blood collection with an open needle and syringe and catheter collections. Moreover, this document neither addresses patient consent, test ordering, sample handling and transport nor collection from children and unconscious patients. The recommended procedure is based on the best available evidence. Each step was graded using a system that scores the quality of the evidence and the strength of the recommendation. The process of grading was done at several face-to-face meetings involving the same mixture of stakeholders stated previously. The main parts of this recommendation are: 1) Pre-sampling procedures, 2) Sampling procedure, 3) Postsampling procedures and 4) Implementation. A first draft of the recommendation was circulated to EFLM members for public consultation. WG-PRE-LATAM was also invited to comment the document. A revised version has been sent for voting on to all EFLM and COLABIOCLI members and has been officially endorsed by 33/40 EFLM and 21/21 COLABIOCLI members. We encourage professionals throughout Europe and Latin America to adopt and implement this recommendation to improve the quality of blood collection practices and increase patient and workers safety.</p>

Adesione alle raccomandazioni dei gruppi di studio SIBioC-SIPMeL (Società Italiana di Patologia Clinica e Medicina di Laboratorio) e SID (Società Italiana di Diabetologia) sulla fase preanalitica per la determinazione della glicemia: ancora margini di miglioramento. Risultati di una indagine conoscitiva nazionale
Adherence to the recommendations of the SIBioC-SIPMeL (Società Italiana di Patologia Clinica e Medicina di Laboratorio) and SID (Società Italiana di Diabetologia) study groups on the preanalytical phase for blood glucose measurement: still room for improvement. A National Survey on the state of art.
<p>Introduction: glucose measurement is pivotal in the management of subjects with diabetes mellitus. Laboratories should provide the most useful information to the clinician in order to ensure the best patient outcome.<br />Methods: in October 2019 a survey has been conducted by SIBioC and SIPMeL Study Groups on &ldquo;Diabetes Mellitus&rdquo; and by the Italian Diabetes Society to verify if their recommendations on preanalytical phase have had an impact on Italian laboratory procedures. Fifteen questions were submitted to all SIBioC and SIPMeL members and 190 complete responses were collected, corresponding to around 5% of all Italian laboratories.<br />Results: 74% of the laboratories (n=46) are aware of the recommendations of the &ldquo;Diabetes Mellitus&rdquo; Study Groups, but only 24% apply them. 61% of the first group centrifuges the collection tubes immediately, providing a rapid plasma separation; 9% place the tubes immediately in an ice-water slurry and separate the plasma within 30 minutes. Only 14 of the responders use citrate buffer/sodium EDTA/sodium fluoride (NaF) tube in lyophilic formulation.<br />The survey allowed to determine also which kind of tube is commonly used: for outpatients, 52 (30%) laboratories use serum or heparinized tubes with separator gel, 46 (24%) of the remaining of laboratories use NaF plasma and heparinized plasma tubes. For hospitalized patients, 99 (52%) laboratories utilizes tubes with separator gel or coagulation activator, while 19 (10%) and 15 (8%) respectively use NaF plasma and heparinized plasma. To perform the Oral Glucose Tolerance Test (OGTT), 84 (43%) laboratories uses tubes without glycolysis inhibitors or separator gel, and only 12 laboratories uses tubes with acidified ternary mixture.<br />Conclusion: considering these non-completely satisfactory findings, the educational activity of SIBioC working groups on &ldquo;Diabetes Mellitus&rdquo; and &ldquo;Variability of Extra-analytical phase&rdquo; should be continued, since they appear to be essential for the improvement of the laboratory procedures.</p>
