ABSTRACT
【Objective】 To compare the efficacy and safety of transfusion of suspended RBCs and washed RBCs in patients with positive direct Coombs testing results. 【Methods】 A retrospective analysis was conducted on 98 patients with positive direct Coombs testing results as 2+ or less in the First Affiliated Hospital of Chongqing Medical University from January 2015 to December 2020. Among them, 31 patients, from January 2015 to December 2016, were transfused with washed RBCs and set as the control group; the other 67 patients, from January 2017 to December 2020, transfused with suspended RBCs, were enrolled as the experimental group. The changes of main laboratory indexes and the incidence of transfusion adverse reactions before and after transfusion of 2 U and 4 U RBCs were compared between the two groups to evaluate the efficacy and safety of transfusion. 【Results】 After 2 U and 4 U transfusion, Hb increased by 12±4.967 (g/L) and 23.78±12.736 (g/L) in the control group, while 12.85±7.109 (g/L) and 22.68±9.832 (g/L) in the experimental group, All transfusions of the two groups were effective, and no significant differences in Hb, TBIL, IBIL and LDH were noticed by groups (P>0.05). No significant difference in the incidence of adverse reactions to blood transfusion between the 2 groups was observed (P>0.05). 【Conclusion】 The transfusion of suspended RBCs is safe and effective in patients with positive direct Coombs testing results as 2+ or less, and the transfusion of washed RBCs was unnecessary.
ABSTRACT
【Objective】 To analyze the root causes of adverse events to insufficient plasma transfusion, so as to explore improvement measures, optimize the transfusion strategy and avoid such adverse events. 【Methods】 The root causes of insufficient plasma transfusion were analyzed by health care failure mode and effect analysis, the targeted improvement measures were formulated and the effect was evaluated. 【Results】 After the improvement, the incidence of adverse events to insufficient plasma transfusion decreased significantly.The risk priority value affecting the safety of blood transfusion decreased from 70 to 8, and the proportion of coagulation function test after blood transfusion increased from 44.61%(1 309/2 934)in 2012 to 80.55% (2 187/2 715)in 2019, and plasma transfusion volume per capital increased from 300 mL to 528 mL. PT and APTT values after plasma transfusion in 2019 significantly increased compared with those in 2012. Meanwhile, the proportion of plasma transfusion in hospitalized patients decreased from 3.16% (2 934/92 838)to 2.12%(2 715/128 352). 【Conclusion】 Risk management of quality and safety of blood transfusion by combing healthcare failure mode, effect analysis and root cause analysis(RCA) can improve the risk awareness of clinical blood transfusion, optimize the proportion of plasma transfusion, and is essential to ensure the safety and effectiveness of blood transfusion and improve the prognosis of transfused patients.
ABSTRACT
To cultivate high-quality professionals of transfusion medicine and construct a new mode of undergraduate practice of transfusion medicine. Since 2013, orientation interns in blood transfusion medicine were recruited from the undergraduate program of laboratory medicine, and a new teaching mode of orientation practice of blood transfusion medicine was established from the aspects of teaching staff, rotation of posts, practice content and comprehensive quality. Through the new training mode of orientation practice, excellent transfusion medical professionals with solid basic knowledge, strong operational skills and high comprehensive quality were cultivated. The establishment of the oriented practice mode of blood transfusion medicine is beneficial to the cultivation and output of high-quality transfusion talents and plays a positive role in promoting the development of transfusion medicine education.
