Abstract

Background: Different seasons present varied environmental factors that influence the occurrence of transfusion-driven diseases. Therefore, this study determined the patterns of blood transfusion among hospitalized patients and the effect of season on ABO/Rh phenotypes. Methods: A single-center retrospective cross-sectional study was conducted on 5089 hospitalized patients that were transfused with blood at Sunyani Municipal Hospital. Archived blood transfusion records were retrieved and analyzed using GraphPad Prism, and SPSS. The association, effect size, and yearly trends of transfusion patterns were determined. Results: The majority of the participants were females (63.0% [3208]), 36-49 years old (20.4% [1039]), O phenotype (48.1% [2447]), Rh-positive (93.1% [4737]), and transfused in the rainy season (61.0% [3103]). Patients’ ABO was weakly associated with age (r = 0.07, p≤0.001) and season (r = 0.05, p = 0.008). Eighty percent (4053/5089) of the transfusions were ABO group-specific, and 28.3% (1146/4053) of this occurred at the emergency ward. The source of transfusion request was weakly associated with season (r = 0.1, p≤0.001) and type of transfusion (r = 0.1, p = 0.002). The rainy season (slope: 142.9, p≤0.001) and ABO-specific transfusions (slope: 219.5, p≤0.001) showed consistent increasing trends over the years. Conclusion: Blood transfusion was frequent among females, adults, Rh-positive and O phenotypes, and in the rainy season. Age and season were significantly associated with ABO, but not Rh. A transfusion request was associated with the season and type of transfusion, with the majority of transfusions occurring in the rainy season and emergency ward. There was an increasing yearly trend in blood transfusions. Doi: 10.28991/SciMedJ-2023-05-02-03 Full Text: PDF

季节对输血模式的影响：一项回顾性研究

背景：不同季节的环境因素各不相同，会影响输血引起的疾病的发生。因此，本研究确定了住院患者的输血模式以及季节对 ABO/Rh 表型的影响。研究方法对桑亚尼市立医院 5089 名住院输血患者进行了单中心回顾性横断面研究。研究人员检索了存档的输血记录，并使用 GraphPad Prism 和 SPSS 进行了分析。确定了输血模式的关联性、效应大小和年度趋势。结果大多数参与者为女性（63.0% [3208]）、36-49 岁（20.4% [1039]）、O 表型（48.1% [2447]）、Rh 阳性（93.1% [4737]）、雨季输血（61.0% [3103]）。患者的 ABO 与年龄（r = 0.07，p≤0.001）和季节（r = 0.05，p = 0.008）微弱相关。80%（4053/5089）的输血是针对ABO血型的，其中28.3%（1146/4053）发生在急诊病房。输血请求的来源与季节（r = 0.1，p≤0.001）和输血类型（r = 0.1，p = 0.002）呈弱相关。雨季（斜率：142.9，p≤0.001）和 ABO 特异性输血（斜率：219.5，p≤0.001）呈逐年上升趋势。结论女性、成人、Rh 阳性和 O 型血以及在雨季输血的频率较高。年龄和季节与 ABO 明显相关，但与 Rh 无关。输血申请与季节和输血类型有关，大多数输血发生在雨季和急诊病房。输血量呈逐年上升趋势。Doi: 10.28991/SciMedJ-2023-05-02-03 全文：PDF
