Sažetak
BACKGROUND Analyzing inadequate samples or incorrectly identified samples can lead to fatal consequences, so it is extremely important not to accept them for laboratory testing. Egregious errors of this type can be prevented by educating medical personnel on sampling and handling of the sample prior to measurement and educating laboratory staff thereof and further about acceptance of samples. The aim of this study was to determine whether an educational lecture had any effect on the quantity of the inadequate samples submitted to the Clinical Department of Laboratory Diagnostics, University Hospital Dubrava. MATERIALS AND METHODS The collected data were divided into two groups. The first group contains data on all samples received during the 60 days prior to the training classes held, and the other group of samples during the 60 days after the lecture. The lecture was based on the instructions on the collection of primary samples for medical-biochemical laboratory and was followed by presentations of most frequent preanalytical errors and causes that lead to them. All statistical calculations were performed using Chi sqare test, MedCalc 9.2.0.0. software (Mariakerke, Belgium). RESULTS No statistically significant difference was found for hemolysed sera samples (Chi square = 0.113, P = 0.737), hemolysed coagulation samples (Chi square= 0.798, P = 0.3717), for clot in whole blood and coagulation plasma samples (Chi square = 2.293, P = 0.13) in the number of received inadequate samples before and after organized educational lectures. CONCLUSION Regardless of the educational presentation we found no significant decrease of inadequate samples submitted in Clinical Department for Laboratory Diagnostic. However, it is necessary to take into consideration the sampling of „difficult patients“ that makes certain percentage of inadequate samples inevitable.
