线上医疗问诊因融合了“医疗服务”“信息服务”与“数据支持”而具有“超信息”属性。为探究这一属性下的患者信任架构，文章应用建构主义扎根理论，对40名线上问诊患者进行了半结构式访谈。研究发现，线上问诊中的患者信任生成于多维信息情境，涉及微观个体感知信息、中观平台数据信息和宏观制度信息环境三个层面。不同层面的信任相互作用，最终影响患者的信息采纳行为。研究从多维度分析了患者信任，弥补了以往研究中对平台信息生态关注的不足，为理解线上问诊中患者信任的逻辑提供了理论支持，为促进健康信息服务体系建设提供了思考。

Online Medical consultations are characterized by a "super-information" attribute that emerges from the integration of medical services, information services and data support. To examine how patients form trust under this attribute, the study employs a constructivist grounded-theory approach and conducts semi-structured interviews with 40 online-consultation patients. Findings reveal that patient trust is generated within a multidimensional information context comprising three interrelated layers: micro-level individual perceptual information, meso -level platform data information, and macro-level institutional information environment. Interactions among these layers of trust ultimately shape patients’ information-adoption behaviors. By analyzing patient trust through a multidimensional framework, this study addresses the previous neglect of the platform’s information ecology. The proposed framework provides theoretical insights into the logic of patient trust in online consultations and offers guidance for the development of health-information service systems.
