背景：用药错误通常涉及混淆具有相似名称的药物。减少错误的一种可能的方法是使用“高个子”（Tall Man）字母强调名称之间的差异（例如头孢他啶与头孢脲肟）。以前的研究调查这个问题已经进行了主要是大学生，结果已经混合。目的：探讨高个子的人在其他关键参与groups.Study设计的影响，对药品名称混淆的字母。在实验I（2008年1月至2008年5月在苏格兰格拉斯哥大学进行）中，年轻人和老年人执行相同/不同的判断任务。在实验2（2008年12月和2009年2月之间在英格兰的各个站点进行），医疗从业人员进行了一项任务的基础上电子prescribing.Results：在实验1中，年轻人和老年人的名字混淆错误时，姓名包含高个子的人字母。反应时间表明，高个子的字母吸引了参与者对这些信件的注意力，但读者并不仅仅依赖于这些信件来做出回应。在实验2中，医疗从业者的名称混淆错误时，名称包含高的人letters.Conclusions：总体而言，结果表明，高的人刻字减少药物名称混淆错误的一系列实验室为基础的任务，在年轻人和老年人，和医疗从业者。因此，目前的研究结果提供了一些支持，使用高个子字母作为一个可能的系统变化，可以由药房和制造商，以减少错误造成的药物名称混淆。
Background: Medication errors commonly involve confusion between drugs with similar names. One possible method of reducing error is to emphasize differences between the names using 'Tall Man' (uppercase) letters (e.g. cef-TAZidime vs cefUROxime). Previous studies investigating this issue have been conducted mainly on university students, and results have been mixed.Objective: To investigate the influence of Tall Man lettering on drug name confusion in other key participant groups.Study Design: Two separate experiments were conducted. In Experiment I (conducted at the University of Glasgow, Scotland, between January 2008 and May 2008), younger and older adults performed a same/different judgement task. In Experiment 2 (conducted at various sites in England between December 2008 and February 2009), healthcare practitioners performed a task based on electronic prescribing.Results: In Experiment 1, both younger and older adults made fewer name confusion errors when names contained Tall Man letters. Response times suggested that Tall Man lettering drew participants' attention to those letters, but that readers did not solely rely on these letters in making their response. In Experiment 2, healthcare practitioners made fewer name confusion errors when the names contained Tall Man letters.Conclusions: Overall, results showed that Tall Man lettering reduced drug name confusion errors in a series of laboratory-based tasks, in both younger and older adults, and healthcare practitioners. Thus, the current findings offer some support for the use of Tall Man letters as a possible systems change that could be made by both pharmacies and manufacturers in an effort to reduce error caused by drug name confusion.
