The Colombian National Institute of Health administers the National Information System of Haemovigilance (SIHEVI-INS). Today, SIHEVI-INS constitutes a national blood donor and recipient database, which contains a national deferred donor registry (DDR), allowing blood banks to take acceptance or rejection decisions of a potential donor in real time. The study aimed to determine the rate of people who have made more than one whole blood donation monthly in Colombia, violating the national guideline of intervals between donations (three months for men and four for women), since DDR implementation.
We detected the unique personal identification number of people who, in 30 calendar days, made more than one whole blood donation at any of the 83 blood banks set up in Colombia. There were three comparison periods: 01/01/2018-08/31/2019 (launch of SIHEVI-INS and first national feedback); 09/01/2019-12/31/2020 (second feedback) and 01/01/2021-09/30/2022 (massive incorporation of web services).
For the first period, blood banks accepted 18.0 donations per 1000 people. There was a rate of 28.8 people/10,000 donations who had donated whole blood twice within 30 days. In the second period, there were 17.0 donations/1000 people and a rate of 2.1 people/10,000 donations (OR:14.0 CI95 %:12.2-16.0). For the last period, there were 18.2 donations/1000 people and a rate of 0.9 individuals/10,000 donations (OR:31.3 CI95 %:26.6-36.9, p < 0.001).
DDR reduced by 31 times the acceptance of blood donors who made more than one whole blood donation in the same month. It was necessary to provide periodic feedback and promote web service implementation to reduce this risky behavior.
哥伦比亚国家卫生研究院管理国家血液监测信息系统（SIHEVI-INS）。如今，SIHEVI-INS 构成了国家献血者和受血者数据库，其中包含国家延迟供者登记册（DDR），使血库能够实时做出潜在供者的接受或拒绝决定。本研究旨在确定自 DDR 实施以来，哥伦比亚每月有超过一人进行一次全血捐献的人数比例，违反了国家献血间隔时间指南（男性三个月，女性四个月）。
我们检测了在哥伦比亚 83 个设立的血库中，在 30 个日历日内，有超过一人进行一次全血捐献的个人的唯一身份识别号码。有三个比较期：2018 年 1 月 1 日至 2019 年 8 月 31 日（SIHEVI-INS 推出和第一次国家反馈）；2019 年 9 月 1 日至 2020 年 12 月 31 日（第二次反馈）和 2021 年 1 月 1 日至 2022 年 9 月 30 日（大规模纳入网络服务）。
第一个时期，血库每 1000 人接受 18.0 次献血。有 28.8 人/10000 人在 30 天内两次捐献全血。第二个时期，每 1000 人有 17.0 次献血，有 2.1 人/10000 人捐献（OR：14.0，95%CI95%：12.2-16.0）。最后一个时期，每 1000 人有 18.2 次献血，有 0.9 人/10000 人捐献（OR：31.3，95%CI95%：26.6-36.9，p<0.001）。
DDR 将一个月内多次捐献全血的献血者的接受率降低了 31 倍。有必要提供定期反馈并促进网络服务的实施，以减少这种危险行为。
