Picture archiving and communication system (PACS) has allowed the medical images to be transmitted, stored, retrieved, and displayed in different locations of a hospital or health system. Using PACS in the emergency department will eventually result in improved efficiency and patient care. In spite of the abundant benefits of employing PACS, there are some challenges in implementing this technology like users' resistance to accept the technology, which has a critical role in PACS success.
In this study, we will assess and compare user acceptance of PACS in the emergency departments of three different hospitals and investigate the effect of socio-demographic factors on this acceptance.
A variant of technology acceptance model (TAM) has been used in order to measure the acceptance level of PACS in the emergency department of three educational hospitals in Iran. A previously used questionnaire was validated and utilized to collect the study data. A stepwise multiple regression model was used to predict factors influencing acceptance score as the dependent variable.
Mean age of participants was 32.9 years (standard deviation [SD] = 6.08). Participants with the specialty degree got a higher acceptance score than the three other groups (Mean ± SD = 4.17 ± 0.20). Age, gender, degree of PACS usage and participant's occupation (profession) did not influence the acceptance score. In our multiple regression model, all three variables of perceived usefulness (PU), perceived ease of use (PEU) and the effect of PACS (change) had a significant effect in the prediction of acceptance. The most influencing factor was change with the beta of 0.22 (P value < 0.001).
PACS is highly accepted in all three emergency departments especially among specialists. PU, PEU and change are factors influencing PACS acceptance. Our study can be used as an evidence of PACS acceptance in emergency wards.
图像存档与通信系统（PACS）使医学图像能够在医院或卫生系统的不同地点进行传输、存储、检索和显示。在急诊科使用PACS最终将提高效率并改善患者护理。尽管采用PACS有诸多益处，但在实施这项技术时仍存在一些挑战，比如用户对接受该技术存在抵触情绪，而这对PACS的成功起着关键作用。
在本研究中，我们将评估和比较三家不同医院急诊科对PACS的用户接受度，并调查社会人口统计学因素对这种接受度的影响。
采用技术接受模型（TAM）的一个变体来衡量伊朗三家教学医院急诊科对PACS的接受程度。对之前使用过的问卷进行了验证，并用于收集研究数据。使用逐步多元回归模型来预测作为因变量的影响接受度得分的因素。
参与者的平均年龄为32.9岁（标准差[SD]=6.08）。具有专业学位的参与者的接受度得分高于其他三组（均值±标准差=4.17±0.20）。年龄、性别、PACS使用程度和参与者职业对接受度得分没有影响。在我们的多元回归模型中，感知有用性（PU）、感知易用性（PEU）和PACS的影响（变化）这三个变量在接受度预测中均有显著影响。影响最大的因素是变化，其β值为0.22（P值<0.001）。
PACS在所有三个急诊科都得到了高度接受，尤其是在专科医生中。PU、PEU和变化是影响PACS接受度的因素。我们的研究可作为急诊科接受PACS的证据。
