Abstract

Background: Transfusion services aim to maintain sufficient blood inventory to support patients, even with challenges introduced by COVID-19.

Objectives: To review blood usage and wastage before, during, and after COVID-19 surges, and to evaluate effects on inventory.

Methods: In a retrospective review, we evaluated the association between time periods corresponding to the initial wave of COVID-19 (pre-COVID-19, quarantine, and postquarantine) and blood usage/wastage. Data were stratified by period, and χ2 testing was used to examine the association between these time periods and blood usage/wastage.

Results: In the period before COVID-19, the transfusion service used more units, and in the period after quarantine, more units went to waste. Across all time periods, the most-used product was RBCs, and the most wasted product was plasma. A statistically significant association existed between usage (χ2 [6/3209 (0.2%)]) = 24.534; P ≤.001; Cramer V = 0.62), wastage (χ2 [6/775 (0.8%)]) = 21.673; P = .001; Cramer V = 0.118), and time period. The postquarantine period displayed the highest wastage costs ($51,032.35), compared with the pre-COVID-19 period ($29,734.45).

Conclusion: Changes in blood inventory use and waste are significantly associated with the onset and continuation of COVID-19.

一家学术教学医院在 COVID-19 初潮前、隔离期间和隔离后的血液使用和浪费情况。

背景：即使 COVID-19 带来了挑战，输血服务仍要保持足够的血液库存以支持患者：即使 COVID-19 带来了挑战，输血服务也要保持足够的血液库存以支持患者：回顾 COVID-19 浪潮之前、期间和之后的血液使用和浪费情况，并评估对库存的影响：在一项回顾性研究中，我们评估了与 COVID-19 最初浪潮相对应的时间段（COVID-19 之前、隔离和隔离之后）与血液使用/浪费之间的关联。数据按时间段进行分层，并使用χ2检验来检验这些时间段与用血量/浪费率之间的关联：结果：在 COVID-19 之前，输血服务使用了更多的血液单位，而在隔离之后，浪费了更多的血液单位。在所有时间段内，使用最多的产品是红细胞，浪费最多的产品是血浆。使用量（χ2 [6/3209 (0.2%)]) = 24.534；P≤.001；Cramer V = 0.62）、浪费量（χ2 [6/775 (0.8%)]) = 21.673；P = .001；Cramer V = 0.118）和时间段之间存在统计学意义上的显著关联。与 COVID-19 前（29,734.45 美元）相比，检疫后时期的浪费成本最高（51,032.35 美元）：结论：血液库存使用和浪费的变化与 COVID-19 的开始和持续密切相关。
