DESCRIPTION (provided by applicant): Blood product transfusion errors continue to pose a significant risk to patients nationwide. Most blood product transfusion errors are the result of incorrect identification of the patient, blood samples for type and cross match, or blood components. To increase the safety of patients undergoing transfusions and reduce the risk of adverse events, it is necessary to ensure that patients, blood samples, and blood products are accurately identified throughout the entire transfusion process. The specific aim of this project is to track and execute identity checks when blood samples are collected, transported, and analyzed, and when blood products are released from the Blood Bank and administered to patients. These identity checks would be facilitated by providing the frontline personnel with handheld wireless barcode devices at the point of care. Barcodes attached to blood products and patients will be scanned and the resulting information will be fed automatically into a new online "check" application that will provide immediate notification of any mismatches. At each critical checkpoint in the process of blood transfusion, staff members will utilize the new application, thereby ensuring that all transactions will be electronically logged and monitored. The project will be implemented in stages, with problems being addressed in pilot tests. The efficacy of the project will be assessed by comparing the proportion of mislabeled blood specimens, mislabeled blood products, and misidentified patients before and after the implementation of the project. The chi-square test of two proportions will be used to assess whether changes in these proportions are significant. Changes in the types of transfusion errors and in the time required for each step of the transfusion process will be tracked to ensure that the intervention was successful. This project will also create the information systems technology necessary for numerous other patient safety efforts. Thus, this project will maximize the benefit from the resources invested. In addition, to date there are no studies in the literature that document the efficacy of barcoding technology for improving patient safety. This project was designed to fill that gap.

描述（由申请人提供）：血液制品输注错误继续对全国患者构成重大风险。 大多数血液制品输注错误是由于对患者、血样类型和交叉配型或血液成分的错误识别造成的。 为了提高输血患者的安全性，降低不良事件的风险，有必要确保在整个输血过程中准确识别患者、血液样本和血液制品。 该项目的具体目标是在采集、运输和分析血液样本时，以及在从血库释放血液制品并向患者提供血液制品时跟踪和执行身份检查。 通过在护理点为一线人员提供手持无线条形码设备，可以促进这些身份检查。 附在血液制品和患者身上的条形码将被扫描，所得信息将自动输入到新的在线“检查”应用程序中，该应用程序将立即通知任何不匹配情况。 在输血过程中的每个关键检查点，工作人员将使用新的应用程序，从而确保所有交易都以电子方式记录和监控。 该项目将分阶段实施，通过试点解决问题。 通过比较项目实施前后血液标本、血液制品、患者的错误识别比例来评估项目的效果。 将使用两个比例的卡方检验来评估这些比例的变化是否显着。 将跟踪输血错误类型和输血过程每个步骤所需时间的变化，以确保干预成功。 该项目还将创建许多其他患者安全工作所需的信息系统技术。 因此，该项目将从所投资的资源中获得最大的效益。 此外，迄今为止，文献中还没有研究证明条形码技术对于提高患者安全的功效。 该项目旨在填补这一空白。
