Abstract

BACKGROUND

Medication management processes in an Oncology setting are complex and difficult to examine in isolation from interrelated processes and contextual factors. This qualitative study aims to evaluate the usability of an Electronic Medication Management System (EMMS) implemented in a specialised oncology unit using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework.

METHODS

The study was conducted in a 12-bed outpatient Oncology unit of a major teaching hospital 6 months following implementation of a commercial EMMS. In-depth semi-structured interviews were conducted with doctors, nurses and pharmacists using the system to assess usability. The UTAUT framework was used to analyse the results, which facilitated evaluation of interrelated aspects and provided a structured summary of user experience and usability factors.

RESULTS

Direct cross-comparison between user groups illustrated that doctors and pharmacists were generally satisfied with the facilitating conditions (hardware and training), but had divergent perceptions of performance (automation, standardised protocols and communication and documented) and effort (mental and temporal demand) expectancy. In counterpoint, nurses were generally satisfied across all constructs. Prior experience using an alternative EMMS influenced performance and effort expectancy and was related to early dissatisfaction with the EMMS. Furthermore, whilst not originally designed for the healthcare setting, the flexibility of the UTAUT allowed for translation to the hospital environment.

CONCLUSION

Nurses demonstrated overall satisfaction with the EMMS, whilst doctors and pharmacists perceived usability problems, particularly related to restricted automaticity and system complexity, which hindered perceived EMMS success. The study demonstrates the feasibility and utility of the UTAUT framework to evaluate usability of an EMMS for multiple user groups in the Oncology setting.

摘要

背景

肿瘤学环境中的药物管理流程复杂，难以与相关流程和背景因素隔离开来进行检查。本定性研究旨在使用统一技术接受和使用理论（UTAUT）框架评估在专门肿瘤学病房中实施的电子药物管理系统（EMMS）的可用性。

方法

该研究在一家主要教学医院的 12 张门诊肿瘤病房中进行，在实施商业 EMMS 后 6 个月进行。使用该系统对医生、护士和药剂师进行深入的半结构化访谈，以评估可用性。使用 UTAUT 框架分析结果，这有助于分析相关方面，并提供用户体验和可用性因素的结构化总结。

结果

直接对用户组进行交叉比较表明，医生和药剂师普遍对便利条件（硬件和培训）感到满意，但对性能（自动化、标准化协议和沟通以及记录）和努力（心理和时间需求）期望有不同的看法。相比之下，护士普遍对所有构念感到满意。使用替代 EMMS 的先前经验影响了性能和努力期望，并与对 EMMS 的早期不满有关。此外，虽然最初不是为医疗保健环境设计的，但 UTAUT 的灵活性允许将其转化为医院环境。
