Background and objectives

Picture Archiving and Communication System (PACS) can be considered as one of the most important information systems used in healthcare facilities and its usability problems can lead to delays in the acceptance of information systems, increased medical errors and also user dissatisfaction. The primary purpose of this study was to evaluate the usability of PACS from the perspective of its main users.

Methods

This study used a combination of qualitative and quantitative methods and was carried out in 2019 where the research community consisted of PACS in five selected companies in Iran. The statistical sample included 200 individuals using the PACS in several hospitals across the country. Moreover, the sample was selected using the multistage random method. The data were then collected using the standard Computer System Usability Questionnaire (CSUQ) consisting of 5 sections and 19 items. Finally, the data were analyzed by SPSS software, version 18 using both descriptive and inferential methods. Content analysis was done for the qualitative data sets.

Results

It was indicated that ease of use, as a category, was not significantly different from the perspective of various PACS users. However, the ANOVA test revealed that there were significant differences in terms of information quality, user interface quality, overall user satisfaction and usability of PACS from the users’ perspectives. Furthermore, content analysis of users' comments showed that speeding up the image processing and frequent system failures were amongst the most positive and negative aspects of the PACS, respectively.

Conclusions

According to the perspective of the users of the investigated PACS in Iran, the usability of these PACS had a favorable status regarding ease of use while provided lower information quality. Generally, based on the users’ viewpoints, the PACS from Company B were the most usable while the PACS provided by Company D were the least usable. It is suggested that the information quality and user interface of systems be improved by using appropriate analysis and needs assessment of the end users.

国家一级选定图片存档和通信系统的可用性评估:用户观点分析

背景和目标

图片存档和通信系统(PACS)可被认为是医疗机构中使用的最重要的信息系统之一,其可用性问题可能导致信息系统接受时间延迟,医疗错误增加以及用户不满意。这项研究的主要目的是从主要用户的角度评估PACS的可用性。

方法

这项研究结合了定性和定量方法,于2019年进行,研究社区由PACS在伊朗的五家选定公司组成。统计样本包括全国各地多家医院中使用PACS的200个人。此外,使用多阶段随机方法选择样本。然后使用标准计算机系统可用性问卷(CSUQ)收集数据,该问卷由5个部分和19个项目组成。最后,使用描述性和推断性方法,通过SPSS 18版的数据进行分析。对定性数据集进行了内容分析。

结果

据指出,从各种PACS用户的角度来看,易用性作为一个类别并没有显着差异。但是,ANOVA测试表明,从用户角度来看,PACS在信息质量,用户界面质量,总体用户满意度和可用性方面存在显着差异。此外,对用户评论的内容分析表明,加速图像处理和频繁的系统故障分别是PACS的最积极和最消极的方面。

结论

根据伊朗接受调查的PACS的用户的观点,这些PACS的可用性在易用性方面处于有利地位,同时提供的信息质量较低。通常,基于用户的观点,B公司的PACS最有用,而D公司提供的PACS最少。建议通过对最终用户进行适当的分析和需求评估来提高系统的信息质量和用户界面。
