Background: Numerous studies indicate that most error sources in hemostasis laboratories occur during the pre preanalytical phase through biological product sampling.
Objectives: The purpose of this study was documentation, monitoring, and reduction of preanalytical errors through operator training.
Methods: For a period of 4 months in the "St. Spiridonˮ Hospital from Iaşi, 978 specimens were identified with non-conformities, due to the following causes: insufficiently-collected, hemolyzed- and coagulated samples. Data collection was conducted in two stages: before and after training of medical staff in clinical departments, upon improving the coagulation specimen sampling practices.
Results: The study pointed out that subsequent to training, a reduction of the coagulated samples has been registered as follows: in medical departments from 33.33% to 16.78%, in surgery from 27.20% to 17.02%, ICU (intensive care units) from 10.63% to 8.74%, and slightly in EU (emergency) from 10.63% to 8.74%. Moreover, we noticed that the incidence of hemolyzed samples increased in clinical sections, as follows: EU from 4.50% to 14.89%, medical departments from 3.42% to 9.21%, surgery from 1.44% to 6.38%, and 4.50% to 14.89% for ICU. The insufficiently sampled volume persisted during the study in almost all sections: surgery from 1.80% to 4.96%, medical from 2.52% to 4.96%, EU from 1.80% to 3.78% with a slight decrease in ICU from 1.26% to 1.18%.
Conclusions: Nurses traditionally represent the core of quality medical services. Peer education is effective and implementation and compliance of sample collection procedure rules ultimately providing patient safety.
