Abstract

Purpose: This study was conducted to investigate the incidence of blood hemolysis and repeated blood sampling and to identify factors contributing to hemolysis and repeated blood sampling in the emergency department. Methods: A cross-sectional descriptive design was used. Participants were the patients who came to emergency department and are required a blood sampling for electrolyte level. All blood samples were collected by emergency department nurses and determined for hemolysis by experienced laboratory technologists. Data were analyzed using $x^2$-test, Fisher's exact test, Mann-Whitney u test and Binary Logistic Regression to determine significant differences. Results: A total of 402 valid samples were collected. Of these, 30 blood samples (7.5%) were found to be hemolyzed and 9 (2.2%) to be recollected. Statistically significant factors affecting on hemolysis and repeated blood sampling included the time of bloods sampling (night), the time of tourniquet application, and too-fast blood draw into the test tube. Conclusion: We recommend that nurses who take the blood sampling to consider the findings of the study and take the related factors into account as they set up the standardized care protocol in order for nursing quality improvement.
