To ensure an adequate and safe blood supply, it is crucial to select suitable donors according to stringent eligibility criteria. Understanding the reasons for donor deferral can help in planning more efficient recruitment strategies and evaluating donor selection criteria. This study aims to define donor pre-donation deferral rates, causes of deferral, and characteristics of deferred donors in Dubai.
This retrospective study was conducted on all donors who presented for allogeneic blood donation between January 1, 2010, until June 30, 2013, in Dubai Blood Donation Centre, accredited by the American Association of Blood Banks. The donation and deferral data were analyzed to determine the demographic characteristics of accepted and deferred donors, and frequency analyses were also conducted.
Among 142,431 individuals presenting during the study period, 114,827 (80.6%) were accepted for donation, and 27,604 (19.4%) were deferred. The overall proportion of deferrals was higher among individuals less than 21 years old (35%, <0.000), females (44% were deferred compared to 15% of males, <0.0001), and first-time donors (22% were deferred vs 14% of repeat donors, <0.0001). The main causes for a temporary deferral were low hemoglobin and high blood pressure.
The deferral rate among blood donors in Dubai is relatively high compared to the internationally reported rates. This rate was higher among first-time donors and females, with low hemoglobin as the major factor leading to a temporary deferral of donors. Strategies to mitigate deferral and improve blood donor retention are urged in Dubai to avoid additional stress on the blood supply.
为确保充足且安全的血液供应，依据严格的合格标准挑选合适的献血者至关重要。了解献血者延期献血的原因有助于规划更有效的招募策略以及评估献血者选择标准。本研究旨在确定迪拜献血者献血前延期献血率、延期原因以及延期献血者的特征。
本回顾性研究针对2010年1月1日至2013年6月30日期间在经美国血库协会认证的迪拜献血中心进行异体献血的所有献血者展开。对献血和延期献血数据进行分析，以确定被接受献血者和延期献血者的人口统计学特征，并进行频率分析。
在研究期间前来献血的142,431人中，114,827人（80.6%）被接受献血，27,604人（19.4%）被延期献血。21岁以下人群（35%，<0.000）、女性（44%被延期，而男性为15%，<0.0001）以及首次献血者（22%被延期，而复献血者为14%，<0.0001）中延期献血的总体比例更高。临时延期的主要原因是血红蛋白水平低和血压高。
与国际报道的比率相比，迪拜献血者的延期献血率相对较高。首次献血者和女性中的这一比率更高，血红蛋白水平低是导致献血者临时延期的主要因素。敦促迪拜采取策略减轻延期献血情况并提高献血者保留率，以避免给血液供应带来额外压力。
