摘要目的:基于整合型信息技术接受与使用模型探讨行经皮冠状动脉介入治疗（PCI）术后患者使用移动健康管理APP的意愿及其主要影响因素。方法:采用便利抽样法，于2021年7—11月选取安徽省2所三甲医院心血管内科病房的308例PCI术后患者为研究对象，采用一般资料调查问卷、PCI术后患者移动健康管理APP使用意愿调查问卷对其进行调查。应用结构方程模型分析PCI术后患者使用意愿的影响因素及路径关系。结果:促成因素、努力期望、社会影响对PCI术后患者使用意愿有正向影响（ P<0.05），效应值分别为0.554、0.247、0.138。感知风险和努力期望对PCI术后患者绩效期望有影响（ P<0.05）。 结论:多方位增强技术支持、发挥医护人员、重要亲友和新媒体的宣传作用、提升产品的易用性，有助于提高PCI术后患者对移动健康管理APP的使用意愿。

abstractsObjective:To explore the willingness and main influencing factors of using mobile health management APP in patients after percutaneous coronary intervention (PCI) based on integrated information technology acceptance and use model.Methods:From July to November 2021, a total of 308 patients after PCI in Department of Cardiovascular Medicine of two ClassⅢ Grade A hospitals in Anhui Province were selected as the research objects by the convenient sampling method. The general information questionnaire and the questionnaire on patients' willingness to use mobile health management APP were used to investigate the patients after PCI. Structural equation model was used to analyze the influencing factors and path relationship of patients' willingness to use after PCI.Results:Contributing factors, effort expectation and social influence had positive effects on patients' willingness to use PCI ( P< 0.05) , and the effect values were 0.554, 0.247 and 0.138, respectively. Perceived risk and effort expectation had effects on performance expectation of patients after PCI ( P<0.05) . Conclusions:Enhancing technical support in various ways, giving play to the publicity role of medical staff, important relatives and friends and new media and improving the ease of use of products can help improve the willingness of patients to use mHealth APP after PCI.
