Exploration of the relationship between the storage time of leukodepleted red blood cell and transfusion adverse reactions / 中国输血杂志

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.

Reporting System of Transfusion Adverse Reaction Using Electronic Medical Records Data / 대한수혈학회지

BACKGROUND: Rapid and sensitive detection of transfusion adverse reaction is fundamental to reducing transfusion-related morbidity and mortality. The aim of this study was to develop an effective system for reporting of transfusion adverse reaction. METHODS: Inpatient lists with transfusion adverse reaction on a nurse electronic medical records (EMR) from December 4th, 2014 to May 21st, 2015 were automatically selected and displayed to the computer screen of the blood bank data management system. After review of clinical and laboratory data of suspected patients with transfusion reaction, frequency of transfusion adverse reaction according to blood components was calculated. RESULTS: The frequency of transfusion adverse reactions according to blood components was, in decreasing order, red blood cells (RBC) 0.91% (58/6,404), frozen fresh plasma (FFP) 0.20% (5/2,549), and platelets 0.10% (6/5,728). Of 47 allergic reactions, the relative ratio by blood components was RBC 76.6%, platelets 12.8%, and FFP 10.6%. All of 22 febrile nonhemolytic transfusion reactions were RBC related reactions. CONCLUSION: The online transfusion adverse reaction reporting system based on a nurse EMR is helpful in easy and accurate estimation of transfusion adverse reaction incidence.
