PURPOSE
Information technology is used to support a wide range of highly specified healthcare tasks and services. There is, therefore, a need to understand the factors affecting the acceptance of this technology by healthcare professionals. Physicians are key providers of healthcare services and are among the principal users of hospital information systems. Their acceptance of hospital information systems is hence of great significance when evaluating the success of those systems.
METHOD
The survey methodology was employed to targeted physicians in the selected case hospital for investigating factors affecting physicians' acceptance of hospital information systems. A total of 202 questionnaires were sent out, with 124 completed copies returned, indicating a valid response rate of 61.4%. We used structural equation modeling to analyze the data.
RESULTS
The results indicated that top management support (γ=0.431, p<0.001) had a significant impact on perceived usefulness. Project team competency (γ=0.381, p<0.001) and system quality (γ=0.369, p<0.001) had a significant impact on physicians' perceived ease of use of hospital information systems. Physicians' perceptions of the usefulness (β=0.132, p<0.05, R(2)=0.296) and ease of use (β=0.952, p<0.001, R(2)=0.784) of hospital information systems had a significant impact on the acceptance of the systems, accounting for 81.4% of total explained variance.
CONCLUSIONS
Through the understanding of the identified critical factors affecting physicians' HIS acceptance, the planners and managers should ensure that hospital information systems to be introduced into a hospital are useful and ease to use. Effort should be focuses on providing sufficient top management support, selecting qualified project team members, and delivering higher system quality in addressing physicians' clinical needs. Thus, our research results can help planners and managers understand key considerations affecting HIS development and use, and may be used as a reference for system design, development and implementation.
目的
信息技术被用于支持各种高度专业化的医疗保健任务和服务。因此，有必要了解影响医疗保健专业人员接受该技术的因素。医生是医疗保健服务的主要提供者，也是医院信息系统的主要使用者之一。因此，评估这些系统的成功与否时，医生对医院信息系统的接受程度非常重要。
方法
采用调查方法，针对选定案例医院的医生进行调查，以研究影响医生接受医院信息系统的因素。共发出 202 份问卷，收回 124 份有效问卷，有效回复率为 61.4%。我们使用结构方程模型来分析数据。
结果
结果表明，高层管理支持（γ=0.431，p<0.001）对感知有用性有显著影响。项目团队能力（γ=0.381，p<0.001）和系统质量（γ=0.369，p<0.001）对医生对医院信息系统的易用性感知有显著影响。医生对医院信息系统的有用性（β=0.132，p<0.05，R²=0.296）和易用性（β=0.952，p<0.001，R²=0.784）的感知对系统的接受度有显著影响，占总解释方差的 81.4%。
结论
通过了解影响医生接受 HIS 的关键因素，可以使规划者和管理者确保将要引入医院的医院信息系统具有实用性和易用性。应重点提供足够的高层管理支持，选择合格的项目团队成员，并提供更高的系统质量，以满足医生的临床需求。因此，我们的研究结果可以帮助规划者和管理者了解影响 HIS 开发和使用的关键因素，并可作为系统设计、开发和实施的参考。
