The use of information technology in the health care sector and especially in hospitals offers great potential for improving the quality of services provided and the efficiency and effectiveness of the personnel, but also for reducing the organizational expenses. However, the main question that arises according to the literature is whether hospital personnel are willing to use state of the art information technology while performing their tasks. This study attempts to address this issue by developing and testing a modified technology acceptance model taking into consideration other relevant models found in the literature.
The original TAM has been extended to include some exogenous variables in order to examine HIS acceptance by Greek hospital personnel. Correlation, explanatory and confirmation factor analysis was performed to test the reliability and validity of the measurement model. The structural equation modeling technique has also been used to evaluate the causal model.
The results indicate that perceived usefulness, ease of use, social influence, attitude, facilitating conditions and self-efficacy significantly affect hospital personnel behavioral intention. Training has a strong indirect impact on behavioral intention through the mediators of facilitating condition and ease of use. Furthermore, the existence of significant positive effects between self-efficacy and social influence, perceived usefulness and anxiety, and facilitating conditions and social influence is also supported.
The proposed model can explain 87% of the variance of behavioral intention indicating that the core constructs of the technology acceptance models have a strong and statistically significant influence on hospital personnel usage intention.
在医疗保健部门，尤其是医院中使用信息技术，为提高所提供服务的质量、人员的效率和效能，以及降低组织成本提供了巨大潜力。然而，根据文献提出的主要问题是，医院工作人员在执行任务时是否愿意使用先进的信息技术。本研究试图通过开发和测试一个经过修改的技术接受模型来解决这个问题，该模型考虑了文献中发现的其他相关模型。
原始的技术接受模型（TAM）已得到扩展，纳入了一些外生变量，以检验希腊医院工作人员对医院信息系统（HIS）的接受情况。进行了相关性分析、解释性分析和验证性因素分析，以测试测量模型的可靠性和有效性。还使用了结构方程建模技术来评估因果模型。
结果表明，感知有用性、易用性、社会影响、态度、便利条件和自我效能感对医院工作人员的行为意向有显著影响。培训通过便利条件和易用性的中介对行为意向有强烈的间接影响。此外，自我效能感与社会影响、感知有用性与焦虑，以及便利条件与社会影响之间存在显著的正向影响也得到了支持。
所提出的模型可以解释行为意向方差的87%，这表明技术接受模型的核心构念对医院工作人员的使用意向有强烈且具有统计学意义的影响。
