Supported by a grant from the Agency for Healthcare Research and Quality, a University of Iowa Hospitals and Clinics interdisciplinary research team created an online data-capture-response tool utilizing wireless mobile devices and bar code technology to track and improve blood products administration process. The tool captures 1) sample collection, 2) sample arrival in the blood bank, 3) blood product dispense from blood bank, and 4) administration. At each step, the scanned patient wristband ID bar code is automatically compared to scanned identification barcode on requisition, sample, and/or product, and the system presents either a confirmation or an error message to the user. Following an eight-month, 5 unit, staged pilot, a 'big bang,' hospital-wide implementation occurred on February 7, 2005. Preliminary results from pilot data indicate that the new barcode process captures errors 3 to 10 times better than the old manual process.
在医疗保健研究与质量局的一项拨款支持下，爱荷华大学医院及诊所的一个跨学科研究团队创建了一个在线数据采集-响应工具，该工具利用无线移动设备和条形码技术来跟踪和改进血液制品的管理流程。该工具可采集：1）样本采集；2）样本抵达血库；3）从血库发放血液制品；4）血液制品输注。在每一步骤，扫描的患者腕带ID条形码会自动与申请单、样本和/或产品上扫描的识别条形码进行比对，系统会向用户显示确认信息或错误信息。经过为期八个月、分五个阶段的试点后，2005年2月7日在全院范围内进行了“大爆炸式”实施。试点数据的初步结果表明，新的条形码流程捕获错误的能力比旧的手工流程高出3至10倍。
