This study investigated the factors affecting the acceptance of hospital electronic health record (EHR) adoption by users based on Technology Acceptance Model3 (TAM3).
The self-administered TAM3 questionnaire was used for data gathering. Content validity and reliability of the TAM3 questionnaire were measured. The relation between dependent, independent, and mediator variables was analyzed using multiple regression analysis.
The results from 224 users indicated that subjective norm, job relevance, output quality, voluntariness, computer experience have significant impacts on perceived usefulness. Also, perceptions of external control and computer anxiety were identified as having significant impacts on perceived ease of use. Perceived usefulness did not have a mediator role between result demonstrability and behavioral intention. Perceived ease of use was not found to be a mediating factor in the relationship between computer self- efficacy and behavioral intention, as well as perceived enjoyment.
The findings of the current study, provide valuable scientific evidence for key affecting factors on hospital EHR in Iran as a developing country. Our results showed the main constructs and relationships depicted in the TAM3 were found to be applicable to assess the adoption of hospital EHR.
本研究基于技术接受模型3（TAM3）调查了影响医院用户接受电子健康记录（EHR）采用的因素。
采用自行填写的TAM3问卷收集数据。对TAM3问卷的内容效度和信度进行了测量。使用多元回归分析来分析因变量、自变量和中介变量之间的关系。
224名用户的结果表明，主观规范、工作相关性、产出质量、自愿性、计算机经验对感知有用性有显著影响。此外，外部控制感和计算机焦虑感被确定为对感知易用性有显著影响。在结果可证明性和行为意向之间，感知有用性没有起到中介作用。在计算机自我效能感与行为意向以及感知愉悦感之间的关系中，未发现感知易用性是一个中介因素。
本研究结果为伊朗作为一个发展中国家医院电子健康记录的关键影响因素提供了有价值的科学证据。我们的结果表明，TAM3中描述的主要结构和关系适用于评估医院电子健康记录的采用情况。
