Study on application of electronic tag to medical safety management system

电子标签是最新的技术之一。这项技术可以用于许多领域，这些天来，经常看到我们熟悉的场景。例如，检票口、仓库的物流管理、商店的防止入店行窃系统等。我院从2004年11月开始使用电子标签的安全管理系统。我们做了这个研究，为了证明这个系统的有效性。我们使用的系统如下。本研究所使用的电子标签的可用频率为13.56MHz，工作人员使用个人数字助理（PDA）读取电子标签上记录的身份证。电子标签贴在工作人员的名片和注射瓶上，或患者的腕带上。当工作人员为患者注射时，使用PDA读取这些ID，并将这些ID与医院信息系统进行核对。在阅读ID后，由于医院信息系统和PDA可以通过无线LAN进行通信，因此可以立即检查患者和药物的组合。当患者ID和药物ID的组合不同时，在PDA的屏幕上显示警告，因此工作人员在犯错误之前注意到。如果病人的ID和药品的ID组合正确，则注射的执行记录会被记录在医院信息系统中，使用该系统后，注射时产生的事件数明显减少，与之前相比与条形码系统相比，一次注射所需的时间也显著减少（p<0.05（p<0.05）。使用电子标签的注射安全管理系统对于防止医疗事故是有效的。并且，该系统对于减轻工作人员的劳动负荷也是有效的。

An electronic tag is one of the newest technology. This technology can be used in many fields and, these days, is often seen also in us the familiar scenes. For example, a ticket gate, the physical distribution management in a warehouse, and the shoplifting prevention system in a store.In our hospital, the safety management system using an electronic tag is used from November, 2004. We did this research, in order to prove the effectiveness of this system.The system which we are using is as follows. The available frequency of the electronic tag used for this research is 13.56MHz.And the staffs read IDs recorded on the electronic tag using the personal digital assistant (PDA). The electronic tag is attached to the staffs name card and injection bottle, or the patient's wristband. When the staff injects a patient, these IDs are read using PDA and these IDs are collated with a hospital information system. After reading ID, by which the combination of a patient and drugs is checked immediately, because a hospital information system and PDA can communicate by wireless LAN.When the combination of a patient's ID and ID of drugs differs, warning is displayed on the screen of PDA, therefore the staff notice, before committing a fault. If a patient's ID and ID of drugs are right combination, the execution record of injection is recorded on a hospital information system.After using this system, the incident number generated when injecting reduced significantly, compared with before (p<0.05).Time required for one injection also decreased significantly as compared with the bar code system (p<0.05).The safety management system for the injection using an electronic tag is effective in order to prevent a medical accident.And, this system is effective, also in order to make the staffs labor load reduce.
