At the Croatian Institute of Transfusion Medicine (CITM), error management has been systematically performed since 2003.Materials and methods.Data derived from error management at the CITM during an 8-year period (2003–2010) formed the basis of this study. Throughout the study period, errors were reported to the Department of Quality Assurance. In addition to surveys and the necessary corrective activities, errors were analysed and classified according to the Medical Event Reporting System for Transfusion Medicine (MERS-TM).Results.During the study period, a total of 2,068 errors were recorded, including 1,778 (86.0%) in blood bank activities and 290 (14.0%) in blood transfusion services. As many as 1,744 (84.3%) errors were detected before issue of the product or service. Among th

The sample bottles need to be filled in faultlessly. Even if one letter in your name or details is incorrect, the lab will not test your sample. Also the sample could have clotted due to

Methaemoglobin measurement Essentially, this chapter is a short list of reasons as to why your ABG (or venous biochemistry) measurement may be wrong, i.e. not reflective of what is happening in the patient. In99% of cases, it is a problem with the collection storage and transport of the sample, because these are factors which are subject to human input and thus human error. The self-calibrating blood gas analyser is a dutiful and dependable servant; some sort of failure in its internal workings will only rarely contribute to the error (and usually it will be because some idiot human has improperly calibrated it). Lastly, a tiny fraction of errors are begot bythephysicochemical limitations of the measurement method (eg. when an absurdly high bromine concentration interferes with chloride measurement and returns a spuriously raised chloride concentration value).This whole thing enjoys a rich full discussion in the section dedicated to arterial blood gas analysis. Sources of error due to inappropriate sample collection and handling Source of error in blood gas collection and handling Sample contaminated with bubbles Published information on the errors of ABG sampling arising from the presence of air bubbles comes from Biswas et al (1982). After two minutes, the presence of air bubbles or froth in the syringe had resulted in a significant increase of PaO2 and a decrease in PaCO2. Sample contaminated with venous blood Sample clotted Sample contains too much heparin (liquid heparin dilutes the sample, and causes pH changes) Haemolysis en route to the ABG analyser Inappropriate type of syringe used (gas-tight syringes are needed, rather than evacuated tubes) The sample contains an excessive number of leukocytes, and they have consumed all the ox
