However, in situations without time to perform sufficient testing, all or part of the pretransfusion testing may be skipped to issue blood quickly. This study evaluated the safety of red blood cell (RBC) transfusion released by an emergency blood transfusion protocol through retrospective analysis at a tertiary hospital for eight years. Methods: All RBC transfusions following the emergency blood transfusion protocol from 2011 to 2018 at Seoul National University Hospital were included in the study. Crossmatching and unexpected antibody screening test results conducted after RBC release and the occurrence of hemolytic transfusion reactions were analyzed. Results: A total of 1,541 cases (5,299 RBCs issued) of emergency blood transfusion were identified. RBCs were issued after performing the immediate spin crossmatch without an unexpected antibody screening test in most cases (1,443; 93.64%), while RBCs were issued with no pretransfusion testing in 98 cases (6.36%). Antibody screening tests performed after the issue of RBCs showed that 17 (1.1%) cases were positive. Two units of RBCs from two different cases showed positive antiglobulin crossmatch test results. However, none of them were suspected to be associated with a hemolytic transfusion reaction. Conclusion: The incidence of incompatible RBC release was very low in patients receiving RBC transfusion through the emergency blood transfusion protocol suggesting it can be used safely with minimal risk of hemolytic transfusion reactions caused by incompatible blood transfusions.

The blood screening tests for HIV, HBV, and HCV have substantially improved transfusion safety. The blood screening results of one blood center were investigated because there is little domestic data available on screening tests. Methods: The blood donation records and screening tests results of a supplying blood center were analyzed retrospectively from January 2011 to December 2020 in Korea. Annual first-time donation numbers, sex, and age distribution of donors were investigated during 10 years. The positivity of ALT, HBsAg, anti-HCV, and anti-HIV antibody testing and the positive cases of HIV, HCV, and HBV NAT were inquired. Results: For 10 years, the blood center has collected 1,896,392 units of blood, and male donation was 1,239,873 units, which was 65.38% of total blood donation. ALT abnormal blood units were 2.06% in 2011, 2.14% in 2013, and 0.81% in 2019. The donor screening test showed HBsAg 0.03%, anti-HCV 0.02%, and anti-HIV 0.06% positivity at 2020. NAT yield cases were three with HIV, two with HCV, and 260 with HBV for 10 years. Conclusion: The positivity of serology screening tests of the Hanmaeum blood center showed a decreasing trend, and the transfusion of nucleic acid positive but serologically negative blood could be prevented by performing NAT.

Therefore, this study assessed the management status of the transfusion management division at major medical institutions. Methods: From August 7th to August 18th, 2021, a survey questionnaire was given to laboratory physicians of 10 major medical institutions in Korea, and the installation and operation of the transfusion management division were surveyed. Results: The medical institutions that participated in this survey completed a transfusion management division in the first half of the year. Doctors, nurses, and medical technologists were assigned as medical personnel, and all laboratory physicians were leading the work as the head of the transfusion management division. Regarding the tasks performed at the transfusion management division, all medical institutions conducted a transfusion appropriateness assessment, education related to transfusion, and adverse transfusion reactions. Most medical institutions had difficulties because there was an insufficient basis to calculate the workforce and budget in installing and operating the transfusion management division. Conclusion: There are rarely reference materials for the practice and operation of the transfusion management division, which has no precedent in Korea, so it is often difficult for medical institutions to prepare it. This study will be a reference for medical institutions that need to install a transfusion management division in the future. Efforts should be made to legislate transfusion management fees focused on the academic community.

Methods: An online survey was conducted through internal groupware targeting employees of the Korean Red Cross Blood Center and Blood Laboratory Center. For the blood donor survey, a text message containing the survey URL was sent to 20,000 blood donors on July 31, 2020, and the responses were analyzed. Results: Of those who received text messages, 63.7% of staff and 8.6% of blood donors participated. Of the employees surveyed, the greatest urgency was the need to prepare after COVID-19; strengthening safety and protection measures of employees showed the highest result. In the concern on future blood services, the highest result was the deterioration of blood supply due to decreasing number of blood donors. In a survey of blood donors, 16.0% answered that the spread of COVID-19 had a very negative or somewhat negative effect on the recognition of blood donation, and 80.4% responded positively to sending an ‘emergency disaster message requesting blood donation’ when blood stocks dropped sharply. Conclusion: It is necessary to expand blood donation promotion and prepare systematic blood donor management measures for a stable blood supply during a pandemic, such as COVID-19. The emergency disaster message requesting blood donation helped solve the blood shortage, but it appears that an effective use plan will be needed in the future.

The medical history and laboratory results, including pretransfusion tests of ten patients treated with immune checkpoint inhibitors, were reviewed retrospectively. The median interval from the first administration of immune checkpoint inhibitors to the development of autoantibodies was 12 weeks. In eight patients, only cold autoantibodies were developed.

Of seven patients tested by a direct antiglobulin test, two were negative, and the remaining five were positive for IgG and negative for C3d.

Several factors that can affect the IA titer have been reported. This is the first study to evaluate whether there are IA titer differences between kidney transplantation (KT) and liver transplantation (LT) recipients. Methods: Thirty-eight KT and 32 LT type O recipients, who underwent ABOi KT or LT between March 2013 and March 2018, were enrolled consecutively. The IgM IA and IgG IA titers of the LT and KT recipients at different time points (initial, operation day [day-0], postoperative one week, four weeks, and one year) were evaluated. Results: The LT recipients showed higher initial IgG IA titers than the KT recipients (P=0.01). This higher titer in the LT recipients persisted during the critical phase (from before transplantation to postoperative one week). The IgG and IgM IA titers were similar in the KT and LT recipients at postoperative four weeks.
