目的 运用技术接受理论调查工作实践中电子病历系统(electronic medical record，EMR)的用户感知，分析影响使用行为的外部因素与内在机制，为系统设计提供理论参考。方法 采用机械抽样抽取新疆地区6所医院487名EMR用户为研究对象，设计基于技术接受理论的EMR用户感知行为调查问卷，运用AMOS 16。0结构方程建模工具建立分析模型，分析感知技术、感知过程、结果间相互作用机制。结果 易用性可使用户对诊疗过程复杂性的感知产生显著的负向影响(β=-0。426，P＜0。05)，有用性可对复杂性产生显著的负向影响(β=-0。359，P＜0。05)，有用性可对刚性产生显著的负向影响(β=-0。353，P＜0。05)，复杂性可对用户行为、态度产生显著的负向影响(β=-0。307，P＜0。01)，刚性可对用户行为、态度产生显著的负向影响(β=-0。212，P＜0。05)，易用性无法对有用性感知产生显著的影响(β=0。181，P＞0。05)。结论 感知技术特性与感知过程特性决定了用户使用EMR的态度与行为;厘清影响态度与行为的因素，对持续推动EMR在医疗卫生机构的深入使用具有重要意义。
Research on User Perception Behavior of Xinjiang Electronic Medical Record System from the Perspective of Technology Acceptance Model
Objective Using technology acceptance theory to investigate the user perception of using electronic medical record system in work practice,and to analyze the external factors and internal mechanisms that affect the use behavior,so as to provide theoretical reference for system design.Methods 487 EMR users from 6 hospitals in Xinjiang were selected by systematic sampling as the research object.A questionnaire on EMR users'perception be-havior based on technology acceptance theory was designed.An analysis model was established using AMOS 16.0 structural equation modeling tool to analyze the interaction mechanism among perception technology,perception process and results.Results The ease of use of electronic medical records had a significant negative impact on users'perception of the complexity of the diagnosis and treatment process(β=-0.426,P＜0.05);usefulness had a signifi-cant negative impact on complexity(β=-0.359,P＜0.05),usefulness had a significant negative impact on rigidity(β=-0.353,P＜0.05).Complexity had a significant negative impact on user behavior and attitude(β=-0.307,P＜0.01).Rigidity had a significant negative impact on user behavior and attitude(β=-0.212,P＜0.05),ease of use didn't have any significant impact on perceived usefulness(β=0.181,P＞0.05).Conclusion The characteristics of perception technology and perception process determine the attitude and behavior of users using EMR;Clarifying the factors that affect attitudes and behaviors is of great significance to continuously promote the in-depth use of EMR in medical and health institutions.
