ABSTRACT
【Objective】 To investigate the establishment of multi-center haemovigilance (HV) and the monitoring of adverse reactions to blood donation (ARBD), in order to provide basis for the management of blood donors. 【Methods】 The operation of HV was investigated by questionnaire. The total number of blood donations (including plateletpheresis) and ARBD cases occurred in each blood center from 2014 to 2018 were analyzed. 【Results】 Among the 24 blood centers in this survey, only nine got HV operated. The incidence of ARBD of 19 blood centers that fulfilled the questionnaire was in the range of (0.003~1.151) %. The change trend of number and incidence of ARBD cases were indeterminate. 【Conclusion】 Most blood centers did not got HV established. The incidence of ARBD varied greatly and was indeterminate. The application of HV should be further improved to strengthen ARBD management.
ABSTRACT
【Objective】 To construct an index framework for the evaluation of blood service system resilience under emergency support, and improve the ability of blood centers to deal with emergencies. 【Methods】 The contents of evaluation index system were preliminarily determined through the literature analysis. The Delphi method and analytic hierarchy process(AHP) were used. Experts in relevant fields were consulted to determine the resilience evaluation of indicator framework. Six experts were invited to score the weight of resilience index and finally determined the weight of the index. 【Results】 The resilience evaluation index framework of blood service was established with 5 first-level indicators and 22 second-level indicators. The weights of first-level indicators economic resilience, social resilience, infrastructure resilience, organizational resilience and process resilience were 0.140, 0.071, 0.156, 0.225 and 0.408, respectively. 【Conclusion】 The established evaluation index framework of blood service system resilience is scientific, which provides a reference basis for evaluating the resilience of blood service system.
ABSTRACT
【Objective】 To investigate the establishment of a competitive performance evaluation management program for blood centers to ensure the blood supply. 【Methods】 A competitive performance evaluation system for Blood Donor Service Department of blood centers in eastern Shenzhen was established. The data concerning blood collection after (May to October 2021, the experiment group) and before (the corresponding period in 2020, the control) the launch of evaluation system was compared, including the proportion of total/novel blood donors in fixed donation sites, the donation rate of 400 mL and pre-collection deferral rate; collected units per shift, the average collection volume of staff, and the growth rate of per capita donation; the proportion of first-time/repeated/double-dose platelet apheresis donors; the proportion of transfer-in/transfer-out of red blood cells; the ratio of group to street blood donors. 【Results】 The proportion of total/novel blood donors in fixed donation sites(81.13% vs 75.87%), the donation rate of 400 mL(58.14% vs 57.91%) and pre-collection deferral rate(76.55% vs 65.92%) in the experimental group was higher than that of the control, while the proportion of pre-collection deferral was lower(18.87% vs 24.13%) (P<0.05). Compared by the control, the units collected per shift, the average collection volume of staff and the blood donation per capita at fixed sites in the experiment group increased by 54.29%, 52.21%, and 3.36% (P<0.05). The proportion of first-time platelet donors was greater than that in the control(43.90% vs 19.61%), while the proportion of repeated platelet donors was lower (56.10% vs 80.39%). The proportion of double-dose platelet donors was lower than that in the control(12.62% vs 22.19%) (P<0.05). The amount of red blood cells transfer-in was 0%, lower than 2.38% in the control group(P<0.05), while the amount of red blood cell transfer-out was 1.86%, higher than 0% in the control group (P<0.05). The proportion of group blood donors decreased from 24% to 15.19%, while street blood donors increased from 76% to 84.81% (P<0.05). 【Conclusion】 Proper competitive performance evaluation system can effectively mobilize employee motivation, improve the efficacy of blood collection and internal management, and ensure clinical blood supply.
ABSTRACT
【Objective】 To observe the effect of hydrogen peroxide atomization sterilizer using low concentration hydrogen peroxide disinfectant on the environment and object surface of physical examination area (hereinafter referred to as " physical examination area" ) in blood centers, so as to provide a simple method which is safe, efficient, easy to operate, harmless to human body and has no corrosive effect on equipment. 【Methods】 The physical examination area was disinfected with atomized hydrogen peroxide sterilizer, and the difference of colony number between air and surface before and after disinfection was compared to evaluate the disinfection effect. 【Results】 After disinfection, the hydrogen peroxide residue was detected for 25 times at 5 points, and the results were (0.7~1)ppm, with no statistical difference (P>0.05). 25 tests were carried out at 5 points, and the quartile of the test results was (0~2)CFU/ dish, and the qualified rate was 100%. The test results of bacteria before and after disinfection were statistically significant (P<0.05), which met the requirements of Class Ⅱ environment in Hygienic Standard for Hospital Disinfection(GB15982-2012). After disinfection, the quartile of surface colony detection results of workbench, blood donor seat, screen and door handle were (0~24.1)CFU/cm2, (1.6~55.4)CFU/cm2, (0~7.2)CFU/cm2 and (0~4.8)CFU/cm2, with the qualified rate at 80%, 48%, 100% and 100%, respectively, which were in accordance with the requirements of Class Ⅲenvironment in GB15982-2012. The number of colonies after disinfection at the above detection sites decreased significantly compared with that before disinfection (P<0.05). The surface contact plate pressing method and cotton swab smearing method were used to detect the number of colonies on the surface of sterilized work tables and blood donor seats, and the detection rate of the former was higher than that of the latter, with statistical significance (P<0.05). 【Conclusion】 After disinfection by hydrogen peroxide atomization sterilizer, the hydrogen peroxide residue met the requirements specified in the manual. The terminal disinfection effect of air in the physical examination area environment can meet the Class Ⅱ environmental requirements of GB15982-2012. However, the number of microorganisms on object surface after terminal disinfection was significantly lower than that before disinfection.
ABSTRACT
BACKGROUND: An objective and standardized interview process is important when screening for healthy blood donors. Our aims were to gather opinions of the interviewing nurses at blood centers on the current donor interview and to suggest improvements to the interview. METHODS: We conducted an anonymous survey consisting of five questions regarding the donor health questionnaire, which can be found on the reverse side of the donation record card. The survey targeted the interviewing nurses with more than 1 year of experience at collection sites of the Korean Red Cross and the Hanmaum blood centers. The survey was sent out and gathered via mail, fax or email between September and October of 2010. RESULTS: The average self-deferral rate of donors prior to interview was 7.4%, and 66.7% of the interviewing nurses considered 'taking medicine' as the most common reason for donor self-deferral. The past and current history of disorders was the hardest question for nurses to determine the eligibility of the donors. Having a history of blood transfusion, surgery, tattoo or a piercing procedure, etc. within a year was the most unacceptable reason for deferred donors. The nurses strongly recommended revision of redundant questions as well as re-examining the unsolvable dilemma of questions concerning malaria. CONCLUSION: According to the survey, this study outlines the perspectives of interviewing nurses at blood centers regarding the rate and reasons for self-deferral of blood donors, the difficulties and the suggestions for improving the current donor interview. The results will be helpful in the future when proposing modifications to the donor interview.

BACKGROUND: The donor selection criteria should ensure the safety of both the donors and the recipients of blood products. However, modifications may help promote more blood donors in keeping with the rapidly aging Korean population. Our goal was to gather opinions of the medical staff at blood centers on the current donor selection criteria. METHODS: A survey was sent out via email to 55 medical staff at hospital blood banks, the Korean Red Cross and Hanmaeum blood centers. The survey included 14~16 questions regarding age, weight, donation volume, donation interval and frequency, hemoglobin, blood pressure, pulse rate, and the level of alanine aminotransferase (ALT). RESULTS: Survey responses from 38 out of 55 (69.1%) medical staff were analyzed. The donor selection criteria that showed significantly higher acceptable rates included the upper age limit (71%, P=0.009) and whole blood donation frequency and intervals (68%, P=0.023). The ALT level showed the highest unacceptable rate (84%, P<0.0001) and other criteria with significantly higher unacceptable rates included donor weight (68%, P=0.023) and donation volume (76%, P=0.001). Responses from medical staff at supply blood banks and hospital blood banks showed a significant difference regarding the use of parent/guardian consent forms in blood donors that were 16 years or younger (75% versus 41%, respectively; P=0.0368). CONCLUSION: This study outlines the perspectives of medical staff at blood centers regarding the current donor selection criteria. According to the survey, the ALT level, donor weight, and donation volume should be considered for revision. These results can be referenced in the future when proposing modifications to the donor selection criteria.

BACKGROUND: The recent trends for blood collection and the blood supply were analyzed. METHODS: Data from the annual reports of the Korean Red Cross from 2002 to 2006 were analyzed. RESULTS: The number of donors in 2002~2003 was about 2,530,000, but this decreased to 2,300,000 in the past 3 years with the population's donation rate being 4.7%. By age, those donors between 16~29 years made up 83% of all the donors. As donor verification became possible in real-time, blood collection from the registered deferral donors was decreased. Blood drawn by the KRC made up 98% of all the blood collected in Korea. Plasma collection for fractionation had recently decreased because of the blood shortage for transfusion in hospitals. The collection of single donor platelets has increased to up to 25% of all the platelets used in Korea. The supply of pre-storage leuko-reduced RBCs had increased. The inventory levels of blood components were lower than the proper levels for most of the days in 2006. The rate of discarding outdated blood components was markedly decreased due to a shortage of blood. The positive rate in screening tests for transfusion-related infection was an average of 2.4%. By nucleic acid tests,which were initiated from 2005, 14 cases during the window period (10 cases of HCV and 4 cases of HIV) were detected. CONCLUSION: For insuring a safe supply of blood, the donor information systems and up-to-date tests were deemed to become of good quality. However, the blood shortage should be resolved as soon as possible to maintain a consistent blood supply.
