【摘要】 目的 设计并开发基于微信小程序的ICU机械通气患者智能沟通模式，并评价该模式的可用性。方法 在现况调查和质性访谈的基础上，构建智能沟通模式模块内容初稿，2021年12月进行专家咨询，由多领域团队共同设计，结合微信小程序，开发智能沟通模式。2022年8月—2023年2月，使用方便抽样法选取北京市4所三级甲等医院7个ICU的103例患者和103名护士为调查对象，采用基于技术接受模型改编的调查问卷，对智能沟通模式的可用性进行评价。结果 该小程序主要包含沟通交流、微信用户、使用记录、意见反馈、设置文字大小5大模块。103例受试患者对智能沟通模式的可用性评分为（99.89±3.73）分（满分为105分）。103名受试护士对智能沟通模式的可用性评分为（169.35±4.65）分（满分为175分）。结论 基于微信小程序开发的智能沟通模式，能满足ICU护士与机械通气患者的有效沟通，可应用于临床。更多还原

【Abstract】 Objective To design and develop an intelligent communication mode for mechanically ventilated patients in Intensive Care Unit(ICU) based on WeChat applet,and evaluate its usability. Methods On the basis of the current situation investigation and qualitative interviews,the first draft of the content of the intelligent communication model module was constructed,and expert consultation was conducted in December 2021. A multifield team combined with WeChat applet to design and develop an intelligent communication model. From August2022 to February 2023,103 patients and 103 nurses from a tertiary hospital in Beijing were selected using convenience sampling method,and a questionnaire adapted from the technology acceptance model was used to evaluate the usability of the intelligent communication mode. Results The small program mainly included five modules:communication,WeChat users,usage records,feedback and text size setting. The usability score of the 103patients was(99.89±3.73) out of 105. The usability score of the 103 tested nurses was(169.35±4.65) out of 175.Conclusion The intelligent communication mode developed based on WeChat applet can meet the effective communication between ICU nurses and mechanically ventilated patients,and can be applied to clinical practice.更多还原
