While barcode medication administration (BCMA) systems have the potential to reduce medication errors, they may introduce errors, side effects, and hazards into the medication administration process. Studies of BCMA systems should therefore consider the interrelated nature of health information technology (IT) use and sociotechnical systems. We aimed to understand how the introduction of interruptions into the BCMA process impacts nurses' visual scanning patterns, a proxy for one component of cognitive processing. We used an eye tracker to record nurses' visual scanning patterns while administering a medication using BCMA. Nurses either performed the BCMA process in a controlled setting with no interruptions (n=25) or in a real clinical setting with interruptions (n=21). By comparing the visual scanning patterns between the two groups, we found that nurses in the interruptive environment identified less task-related information in a given period of time, and engaged in more information searching than information processing.
虽然条形码给药系统（BCMA）有减少用药错误的潜力，但它们可能会在给药过程中引入错误、副作用和风险。因此，对BCMA系统的研究应考虑健康信息技术（IT）使用与社会技术系统的相互关联性质。我们旨在了解在BCMA过程中引入干扰如何影响护士的视觉扫描模式，视觉扫描模式可作为认知加工一个组成部分的代表。我们使用眼动仪记录护士在使用BCMA给药时的视觉扫描模式。护士们要么在无干扰的受控环境中执行BCMA过程（n = 25），要么在有干扰的真实临床环境中执行（n = 21）。通过比较两组的视觉扫描模式，我们发现处于干扰环境中的护士在给定时间内识别的与任务相关的信息较少，并且更多地进行信息搜索而非信息处理。
