Meaningful use of picture archiving and communication systems (PACS) can change the workflow for accessing digital images, lead to faster turnaround time, reduce tests and examinations, and increase patient throughput. This study was carried out to identify determinant factors that affect the adoption of PACS by physicians.
This was a cross-sectional study in which 190 physicians working in a teaching hospital affiliated with Tehran University of Medical Sciences were randomly selected. Physicians' perceptions concerning the adoption of PACS were assessed by the conceptual path model of the Unified Theory of Acceptance and Use of Technology (UTAUT). Collected data were analyzed with regression analysis. Structural equation modeling was applied to test the final model that was developed.
The results show that the UTAUT model can explain about 61 percent of the variance on in the adoption of PACS ( = 0.61). The findings also showed that performance expectancy, effort expectancy, social influences, and behavior intention have a direct and significant effect on the adoption of PACS. However, facility condition showed to have no significant effect on physicians' behavior intentions.
Implementation of new technology such as PACS in the healthcare sector is unavoidable. Our study clearly identified significant and nonsignificant factors that may affect the adoption of PACS. Also, this study acknowledged that physicians' perception is a key factor to manage the implementation of PACS optimally, and this fact should be considered by healthcare managers and policy makers.
有效使用图像存档与通信系统（PACS）可以改变获取数字图像的工作流程，缩短周转时间，减少检查和检验，并提高患者通量。本研究旨在确定影响医生采用PACS的决定性因素。
这是一项横断面研究，随机选取了190名在德黑兰医科大学附属教学医院工作的医生。采用技术接受与使用统一理论（UTAUT）的概念路径模型评估医生对采用PACS的看法。收集的数据采用回归分析进行分析。应用结构方程模型对最终构建的模型进行检验。
结果表明，UTAUT模型可以解释约61%的PACS采用差异（=0.61）。研究结果还表明，绩效期望、努力期望、社会影响和行为意向对PACS的采用有直接且显著的影响。然而，设施条件对医生的行为意向没有显著影响。
在医疗领域实施如PACS这样的新技术是不可避免的。我们的研究明确识别了可能影响PACS采用的显著和不显著因素。此外，本研究承认医生的认知是优化管理PACS实施的关键因素，医疗管理者和政策制定者应考虑这一事实。
