Since the SARS-CoV-2 pandemic has been shown to negatively affect blood donation worldwide, the purpose of this study was to assess its impact on voluntary blood donation in Greece from March 2020 to October 2021.
A cross-sectional study was conducted on 764 prospective blood donors (37.3 % men, 62.7 % women). The study utilized a specially developed questionnaire, and the results were statistically analyzed using a two-sided significance level set at 0.05.
Most donors had been informed about blood donation from family/friends (29.5 %). While 83.6 % of the respondents had given blood in the past, only 39.8 % were regular voluntary donors. During the pandemic, 52.2 % of respondents did not donate blood, while 29.3 % cited a relative/friend needing blood. Notably, 95.2 % expressed their willingness to donate if a friend/relative required blood during this period. Donors who had given blood in the past avoided donation during the pandemic (p < 0.001), but voluntary blood donors had a lower degree of re-duction in contrast to family blood donors (p < 0.001). Specifically, family blood donors, who would have donated blood before the pandemic, reduced blood donations (p = 0.027). Finally, blood donors whose lives were affected by the pandemic reported a greater degree of reduction in blood dona-tions.
The study underscores the significant impact of the SARS-CoV-2 pandemic on the frequency of blood donation. Despite a reduction in donations, the findings reveal that volunteer blood donors would positively respond to familial needs during the challenging circumstances of the pandemic.
由于严重急性呼吸综合征冠状病毒2（SARS-CoV-2）大流行已被证明对全球献血产生负面影响，本研究的目的是评估其对2020年3月至2021年10月希腊自愿献血的影响。
对764名潜在献血者（37.3%为男性，62.7%为女性）进行了一项横断面研究。该研究使用了专门设计的问卷，并使用设定为0.05的双侧显著性水平对结果进行了统计分析。
大多数献血者是从家人/朋友那里了解到献血信息的（29.5%）。虽然83.6%的受访者过去曾献过血，但只有39.8%是定期自愿献血者。在大流行期间，52.2%的受访者没有献血，而29.3%的人提到有亲属/朋友需要用血。值得注意的是，95.2%的人表示，如果在此期间朋友/亲属需要用血，他们愿意献血。过去献过血的献血者在大流行期间避免献血（p<0.001），但与家庭献血者相比，自愿献血者的减少程度较低（p<0.001）。具体而言，在大流行前会献血的家庭献血者减少了献血量（p=0.027）。最后，生活受到大流行影响的献血者报告献血量减少的程度更大。
该研究强调了SARS-CoV-2大流行对献血频率的重大影响。尽管献血量有所减少，但研究结果表明，在大流行的挑战性环境下，自愿献血者会积极响应家庭用血需求。
