摘要目的:探究感知利益与感知风险对患者互联网医疗服务持续利用意愿的影响路径，以期助力互联网医疗服务可持续发展。方法:于2023年6—7月，在江苏省南部、中部、北部各选择1个代表城市，在每个抽样城市选择一、二、三级医院各1家，对门诊患者进行问卷调查，问卷内容包括个人基本信息、感知利益、感知风险、信任以及互联网医疗服务持续利用意愿。基于调查结果构建结构方程模型并检验感知利益与风险对患者持续利用意愿的影响和路径。结果:共获得741份问卷。患者对互联网医疗服务持续利用意愿较高，平均得分为5.05分(最高分为7分)。结构方程建模结果显示，感知利益( β＝0.543， P<0.01)和信任( β＝0.211， P<0.01)对患者持续利用意愿的正向影响显著，而感知风险对持续利用意愿的负向影响不显著( β＝－0.072， P＝0.053)。中介效应分析结果显示，患者信任在感知利益与持续利用意愿之间发挥部分中介作用，在感知风险与持续利用意愿之间发挥完全中介作用。 结论:感知利益影响患者互联网医疗服务持续利用意愿，患者信任起部分中介作用；感知风险通过患者信任间接影响患者持续利用意愿。

abstractsObjective:To explore the impact paths of perceived benefits and perceived risks on patients′ continuous utilization willingness of internet healthcare services, so as to support the sustainable development of internet healthcare services.Methods:Using stratified sampling, one representative city was selected from each of southern, central, and northern Jiangsu Province. A questionnaire survey was conducted among outpatients at primary, secondary, and tertiary hospitals in the sampled cities from June to July 2023. The questionnaire covered personal basic information, perceived benefits, perceived risks, patient trust, and continuous utilization willingness of internet healthcare services. A structural equation model was constructed based on the survey results to examine the influence and paths of perceived benefits and risks on patients′ willingness to continuously utilize such services.Results:A total of 741 questionnaires were ultimately included. Patients demonstrated a high willingness to continuously utilize internet healthcare services, with an average score of 5.05(the maximum score was 7 points). Structural equation modeling revealed that perceived benefits ( β=0.543, P<0.01) and trust ( β=0.211, P<0.01) had significant positive effects on patients′ continuous utilization willingness, while perceived risks showed no significant negative effect ( β=-0.072, P=0.053). Patients′ trust partially mediated the relationship between perceived benefits and continuous utilization willingness, while fully mediated the relationship between perceived risks and continuous utilization willingness. Conclusions:Perceived benefits influence patients′ willingness to continuously utilize internet medical services, with trust acting as a partial mediator. Perceived risks indirectly affect patients′ continuous utilization willingness through patient trust.
