Blood transfusion is an intervention used to save life particularly for those patients who survive only with receiving blood. Establishing effective diagnostic test menus concerning the screening of transfusion-transmissible infections in the blood banks play a vital role to safeguard recipients from transfusion-transmissible infections.
The aim of this study was to assess blood transfusion-transmissible malaria and its screening cost analysis in Hawassa regional blood bank, Hawassa, Sothern Ethiopia.
An institutional-based cross-sectional study was conducted from April to May 2018 among 414 voluntary blood donors. Each participant's blood sample was screened for most transfusion-transmissible infections using antigen/antibody tests, while rapid diagnostic test and microscopy were used for malaria screening and confirmation. In addition, the cost screening of transfusion-transmissible infections was calculated using activity-based costing method.
The overall seropositivity of transfusion-transmissible infections was 7.0% and the positivity rate of hepatitis B virus, syphilis, and was 5.6%, 1.0%, and 0.5%, respectively. The cost per test of each transfusion-transmissible infection was US$5.04 for human immunodeficiency virus, US$4.61 for hepatitis B virus, US$5.11 for hepatitis C virus, and US$4.75 for syphilis, while the cost per test of malaria rapid diagnostic test was US$4.74 and this is comparatively lower than the cost per test of other transfusion-transmissible infections except for hepatitis B virus. In addition, total cost of laboratory incurred for transfusion-transmissible infections screening is estimated to be US$213,634.5 per year, while it becomes US$265,537.5 if the malaria screening cost is added. This means 19.54% of the total cost of laboratory incurred per year or US$51,903.
The positivity rate of malaria parasites among voluntary blood donors was 0.5%, and it might be increased if the study was conducted in high transmission seasons. A cost of malaria screening is comparatively lower than costs of other transfusion-transmissible infections except for hepatitis B virus. Therefore, the screening of malaria parasites should be considered as one of the test menus of transfusion-transmissible infections in blood banks, especially in malaria-endemic areas.
输血是一种用于挽救生命的干预措施,尤其适用于那些只有通过输血才能存活的患者。建立有效的诊断检测项目,用于筛查血库中可通过输血传播的感染,对于保护受血者免受此类感染至关重要。
本研究旨在评估埃塞俄比亚南部哈瓦萨地区血库中输血传播性疟疾及其筛查成本分析。
2018年4月至5月,在414名自愿献血者中开展了一项基于机构的横断面研究。使用抗原/抗体检测对每位参与者的血样进行大多数可通过输血传播感染的筛查,同时使用快速诊断检测和显微镜检查进行疟疾筛查和确诊。此外,采用作业成本法计算可通过输血传播感染的筛查成本。
可通过输血传播感染的总体血清阳性率为7.0%,乙型肝炎病毒、梅毒和丙型肝炎病毒的阳性率分别为5.6%、1.0%和0.5%。人类免疫缺陷病毒每项检测成本为5.04美元,乙型肝炎病毒为4.61美元,丙型肝炎病毒为5.11美元,梅毒为4.75美元,而疟疾快速诊断检测每项检测成本为4.74美元,除乙型肝炎病毒外,这一成本相对低于其他可通过输血传播感染的每项检测成本。此外,估计每年用于可通过输血传播感染筛查的实验室总成本为213,634.5美元,若加上疟疾筛查成本则为265,537.5美元。这意味着占每年实验室总成本的19.54%,即51,903美元。
自愿献血者中疟原虫的阳性率为0.5%,如果在高传播季节开展该研究,阳性率可能会增加。除乙型肝炎病毒外,疟疾筛查成本相对低于其他可通过输血传播感染的成本。因此,疟原虫筛查应被视为血库中可通过输血传播感染检测项目之一,尤其是在疟疾流行地区。
