Background

Wrong medication and wrong dosage are major risks in the pharmaceutical industry, as many medication errors occur when dispensing medication. The dispensing process in its current form is limited in verifying the patient's identity before dispensing the medication. Furthermore, this process does not offer a robust method for providing accurate medication intake instructions. Therefore, we have developed a framework to accurately and securely overcome issues associated with transferring patient credentials and prescription information. The long-term goal of this research is to develop a framework to mitigate medication dispensing errors. One of the framework components is the mobile application that uses near-field communication (NFC) to transfer information. Therefore, in this paper, we designed a user study to assess the proposed NFC-based mobile application in terms of usefulness and ease of use compared with the traditional method of picking up a prescribed medication.

Methods

We conducted a usability study with 21 participants to perform four tasks to simulate the process of picking up a prescribed medication using the proposed NFC application method and the traditional method of picking up medication. Then, we asked the participants to complete two post-questionnaires after using each method to evaluate the participants’ experience of the process. Next, we asked the participants to complete an additional questionnaire about the usefulness of the NFC application method. Finally, we conducted semi-structured interviews with the participants to get more evidence to back up the questionnaire answers.

Results

Our findings show that 91% of the participants believe using the NFC application method will improve patient safety during the medication pickup process. Nearly 97% of participants found the NFC application method easy to use. Our findings show that the participants scored lower when using the NFC application method compared with the traditional method when trying to identify the wrong medication after dispensing. In addition, 90% of the participants successfully identified the wrong medication when using the NFC application method, compared to only 38% when using the traditional method. Finally, the results show that the participants preferred using the NFC application method in terms of information availability, security, and privacy.

Conclusions

The study findings show that the proposed NFC application for managing patients’ prescriptions and picking up medication might improve patient safety. The results show that the participants believe the NFC application will mitigate medication dispensing errors, at least from their end. The participants believe the application will provide a fast and accurate method of verifying dispensed medication from the patient end. Moreover, the application will help the patient to track their current prescription, which also helps them remember the medication intake instructions. Finally, the study indicates that the application will provide a secure, private, and accurate method to help verify the patient's identity, thus minimizing medication errors during the medication dispensing process.

降低药物处方和配药错误风险的框架:基于 NFC 的移动应用程序的可用性研究

背景

错误用药和错误剂量是制药行业的主要风险,因为在配药时会发生许多用药错误。当前形式的配药过程仅限于在配药前验证患者的身份。此外,该过程不提供用于提供准确的药物摄入指示的可靠方法。因此,我们开发了一个框架来准确、安全地克服与传输患者凭证和处方信息相关的问题。这项研究的长期目标是开发一个框架来减少配药错误。框架组件之一是使用近场通信 (NFC) 传输信息的移动应用程序。因此,在本文中,

方法

我们对 21 名参与者进行了一项可用性研究,以执行四项任务来模拟使用建议的NFC 应用方法传统的取药方法取药的过程。然后,我们要求参与者在使用每种方法后完成两个事后问卷,以评估参与者对过程的体验。接下来,我们要求参与者完成一份关于NFC 应用方法有用性的额外问卷。最后,我们对参与者进行了半结构化访谈,以获得更多证据来支持问卷答案。

结果

我们的研究结果表明,91% 的参与者认为使用NFC 应用方法将提高患者取药过程中的安全性。近 97% 的参与者认为NFC 应用方法易于使用。我们的研究结果表明,与传统方法相比,在分配后尝试识别错误药物时,参与者在使用NFC 应用方法时得分较低。此外,90% 的参与者在使用NFC 应用方法时成功识别出错误的药物,而使用传统方法时只有 38% 。最后,结果表明参与者更喜欢使用NFC在信息可用性、安全性和隐私方面的应用方法

结论

研究结果表明,拟议的用于管理患者处方和取药的 NFC 应用程序可能会提高患者的安全性。结果表明,参与者相信 NFC 应用程序将减少药物分配错误,至少从他们的角度来看。参与者相信该应用程序将提供一种快速准确的方法来验证从患者端分配的药物。此外,该应用程序将帮助患者跟踪他们当前的处方,这也有助于他们记住药物摄入说明。最后,研究表明该应用程序将提供一种安全、私密且准确的方法来帮助验证患者的身份,从而最大限度地减少配药过程中的用药错误。
