Blood transfusion is a common, essential procedure when treating many different medical and surgical conditions. Efficient utilization of blood bank facilities by frequent auditing is crucial; however, few studies have examined blood utilization in Saudi Arabia. We aimed to review the blood ordering patterns and transfusion practices, and blood bank audit effectiveness at a single center in Saudi Arabia and compare our results with those of a similar study performed in the same center 20 years ago.
This study was a retrospective descriptive chart review of all healthy blood donors and recipients from January 1, 2016, to December 31, 2020. We evaluated the crossmatching-to-transfusion ratio (C/T) as an indicator of blood bank utilization and compared the findings with those of the previous study. We also evaluated changes in blood bank utilization during the coronavirus disease 2019 pandemic.
Findings from 27,414 donors (men, 94.9%; mean age, 32.2 + 9.6 years) showed a 71% increase in blood donations compared to that of 2000. The donations gradually increased over the years, peaking just before COVID-19 pandemic started in March 2020. For 3,836 patients, 13,324 units of blood were crossmatched (average, 3.47 crossmatch/patient), with 23% of the crossmatch requests from surgical departments. The average C/T ratio, transfusion index, and transfusion probability (T%) were 1.37, 2.55, and 73.2%, respectively. The C/T ratio decreased by 54% between 2000 and 2020. During the pandemic, crossmatching decreased by 26% between 2019 and 2020, but with comparable C/T ratio in 2019 (1.45) and 2020 (1.39).
Our hospital blood bank utilization improved over the past 20 years, showing increased donations, reduced C/T ratio, and increased T%. This improvement emphasizes the importance of blood donation campaigns, blood bank auditing, restrictive transfusion guidelines, and physician education.
在治疗许多不同的医疗和外科病症时，输血是一种常见且必不可少的程序。通过频繁的审核来提高血库设施的使用效率至关重要；然而，很少有研究检查过沙特阿拉伯的血液使用情况。我们旨在审查一家沙特阿拉伯单一中心的血液订购模式和输血实践以及血库审核的有效性，并将我们的结果与 20 年前在同一中心进行的类似研究进行比较。
本研究是对 2016 年 1 月 1 日至 2020 年 12 月 31 日所有健康献血者和受血者的回顾性描述性图表审查。我们评估了交叉配血与输血比（C/T）作为血库利用的指标，并将结果与之前的研究进行了比较。我们还评估了 2019 年冠状病毒病（COVID-19）大流行期间血库利用的变化。
来自 27414 名献血者（男性占 94.9%；平均年龄 32.2+9.6 岁）的研究结果显示，与 2000 年相比，献血量增加了 71%。献血量逐年增加，在 2020 年 3 月 COVID-19 大流行开始前达到峰值。3836 名患者共交叉配血 13324 个单位（平均每个患者 3.47 个交叉配血），其中 23%的交叉配血请求来自外科部门。平均 C/T 比、输血指数和输血概率（T%）分别为 1.37、2.55 和 73.2%。2000 年至 2020 年期间，C/T 比下降了 54%。在大流行期间，2019 年至 2020 年期间交叉配血减少了 26%，但 2019 年（1.45）和 2020 年（1.39）的 C/T 比相当。
在过去的 20 年里，我们医院的血库利用得到了改善，表现为献血量增加、C/T 比值降低和 T%增加。这种改进强调了献血运动、血库审核、限制性输血指南和医生教育的重要性。
