卫生专业人员和患者往往会混淆名称相似的药物，从而威胁患者的安全。在美国，四分之一的自愿报告的用药错误涉及这种类型的药物名称混淆。认知心理学提供了深入了解这些错误是如何以及为什么发生的。本研究的目的是检查正交（即，拼写）和语音（即，声音）相似性对产生识别记忆错误的概率的影响（即，虚假声明）。前瞻性，基于计算机的，再认记忆实验进行了30名药剂师和66名大学生。参与者查看了药物名称的研究列表，然后是测试列表。测试列表是两倍长的研究列表，并包含干扰词的名称在逐步增加的相似性水平的研究单词。任务是确定哪些测试名称在研究列表中，哪些是新的。主要的结果测量是产生错误识别错误的概率（即，一个新的名字出现在研究名单上）。在药剂师和大学生中，相似性对错误识别的概率有很强的影响。得出的结论是，两个正字法（即，拼写）和语音（即，声音）相似性增加了专家和新手在试图记住药物名称时犯错误识别错误的可能性。相似性是容易和廉价的测量，因此，应采取措施，以监测和减少相似性的一种手段，减少药品名称混淆的可能性。(C)2001爱思唯尔科技有限公司版权所有。
Health professionals and patients tend to confuse drugs with similar names, thereby threatening patient safety. One out of four medication errors voluntarily reported in the US involves this type of drug name confusion. Cognitive psychology offers insight into how and why these errors occur. The objective of this investigation was to examine the effect of orthographic (i.e., spelling) and phonological (i.e., sound) similarity on the probability of making recognition memory errors (i.e., false recognitions). Prospective, computer-based, recognition memory experiments on 30 pharmacists and 66 college students were conducted. Participants viewed a study list of drug names and then a test list. The test list was twice as long as the study list and contained distracter names at progressively increasing levels of similarity to the study words. The task was to identify which test names were on study list and which were new. The main outcome measure was probability of making a false recognition error (i.e., of saying a new name was on the study list). Among pharmacists and college students, there was a strong and significant effect of similarity on the probability of making a false recognition error. It was concluded that both orthographic (i.e., spelling) and phonological (i.e., sound) similarity increase the probability that experts and novices will make false recognition errors when trying to remember drug names. Similarity is easily and cheaply measured, and therefore, steps should be taken to monitor and reduce similarity as a means of reducing the likelihood of drug name confusions.
