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>

Protocollo operativo per la verifica della comparabilità dei risultati di laboratorio ottenuti su più procedure analitiche
Protocol to verify the comparability of quantitative laboratory results obtained with different measurementprocedures.
<p>With the growth and merging of clinical laboratories, very frequently analytical tests are performed onmultiple instruments within one or multiple locations. In these situations, there is the need of verifying thecomparability of patient results obtained with different analysers and/or different measurement procedures. Theimportance of this verification is further emphasised when considering that it is included into the ISO 15189specifications. This protocol provides step-by-step guidance on how to assess results comparability in differentscenarios. Up to four experimental designs are presented to meet laboratories&rsquo; needs, with details and examples onfrequency of testing, definition of acceptability criteria, samples selection, sample size calculation, statistical analysisand reporting.</p>

Protocollo per la comparazione di due metodi analitici di laboratorio
Protocol for the comparison of two laboratory methods
<p>Method comparison is one of the main concerns in&nbsp;Laboratory Medicine. With the introduction of new methods with potential advantages (e.g., cost reduction, improvement&nbsp;in efficiency, easier procedures and maintenance) the laboratory staff should investigate if the field method in use may&nbsp;be replaced by the new candidate method without compromising analytical quality nor resulting in a different medical&nbsp;decision or patient management. Several statistical approaches and graphical tools are available to investigate sources&nbsp;of analytical error and for decision-making. In this article, we present an operative protocol for the comparison of two&nbsp;quantitative analytical methods. All sequential steps, including experimental design, familiarization with the new method,&nbsp;quality assessment, sample selection, definition of acceptability criteria, sample measurement, data analysis and&nbsp;evaluation, final decision and reporting, are discussed and exemplified.</p>
