RESUMO
Background@#This study investigated the recognition of employees and blood donors regarding the spread of COVID-19 and the response of the Korean Red Cross Blood Service. @*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.
RESUMO
Background@#The purpose of this study was to prepare data for the prevention and management of iron deficiency by analyzing the effects of taking iron supplements provided by blood centers for repeat blood donors. @*Methods@#The high-risk groups with a potential iron deficiency were defined as three or more whole blood donations within the previous year and were provided with iron supplements for three months. Their hemoglobin and ferritin levels were checked up once a month for six months. The effectiveness of the iron supplements was evaluated by analyzing the changes in the initial and monthly hemoglobin and ferritin results. @*Results@#At the time of recruitments, an average 50.4% (40.8% of men and 65.3% of women, respectively) of participants had ferritin levels of less than 15 ng/mL, the World Health Organization iron deficiency standard, but after three months iron supplementation, the results decreased to 10.9% (9.0% of men and 13.8% of women). The ferritin levels increased significantly after taking iron supplements for three months and showed significant increases in both men and women, particularly after two months (P＜0.05). @*Conclusion@#The dietary iron supplements containing low-dose iron were effective in preventing iron deficiency in repeat blood donors by increasing the ferritin levels.
