目的 针对重症医学领域中医患沟通的核心问题，应用ICU智能导引科普系统，以提高家属认知度，助力医务人员有效沟通。方法 采用非随机对照的类实验研究，便利选取2024年1月—8月成都市某三级甲等医院收治的160例ICU患者及家属为研究对象，2024年5月—8月为试验组（n=80）接受基于智能导引科普系统的标准化、结构化宣教，2024年1月—4月为对照组（n=80）接受常规宣教（口头讲解+纸质材料）。通过标准化问卷调查评估并比较两组患者家属对ICU核心知识（环境、流程、治疗、预后等）的认知度、总体满意度、医护沟通满意度、医疗纠纷/疑虑发生率，并对沟通信息传递质量（完整性、清晰度、及时性）进行评价。结果 相较于传统宣教，接收智能导引系统的患者和家属满意度明显更高，满意度分别为98%和88%（χ²=5.710，P=0.017），相应的医护满意度也比传统宣教更高，满意度分别为98%和86%（χ²=6.920，P=0.008），纠纷发生率显著更低，分别为2.5%和15.0%（χ²=8.273，P=0.004）。在沟通效率方面，接受智能导引系统的患者及家属在完整性[分别为（4.6±0.5）分和（3.8±0.9）分，t=7.320，P<0.001]、清晰度[分别为（4.4±0.6）分和（3.6±1.0）分，t=8.040，P<0.001]、及时性[分别为（4.3±0.7）分和（3.2±1.1）分，t=8.040，P<0.001]、互动的参与感[分别为（8.5±1.2）分和（6.1±1.8）分，t=10.450，P<0.001）]方面均优于传统宣教，医护人员耐心比例显著更高（分别为87.5%和70.8%，χ²=6.670，P=0.010）。结论 ICU智能导引科普系统在改善患者及家属对ICU的认知、医患沟通和满意度方面效果显著，需要进一步开展随机对照试验进行验证。该研究为重症医学领域的科普健康教育提供了新范式，对推进智慧医疗建设具有参考价值。

Objective To address the core issues of doctor-patient communication in critical care medicine，an ICU full-cycle intelligent science popularization management system was developed to enhance family members’ cognition and facilitate effective communication by medical staff. Methods A non-randomized controlled quasi-experimental study was conducted. Convenience sampling was used to select 160 ICU patients and their families admitted to a tertiary hospital in Chengdu from January to August 2024. The control group（n=80，January-April 2024） received conventional education（verbal explanations + printed materials），while the intervention group（n=80，May-August 2024） received standardized，structured education via an intelligent guidance system. Standardized questionnaires were used to assess and compare the two groups in terms of family members’ understanding of ICU core knowledge（environment，procedures，treatment，prognosis，etc.），overall satisfaction，satisfaction with medical communication，incidence of medical disputes/concerns，and the quality of information delivery（completeness，clarity，and timeliness）. Results Compared to conventional education，the intelligent guidance system significantly improved patient and family satisfaction（98% and 88%，χ²=5.710，P=0.017），as well as medical staff satisfaction（98% and 86%，χ²=6.920，P=0.008），while reducing dispute rates（2.5% and 15.0%，χ²=8.273，P=0.004）. In communication efficiency，the intervention group outperformed the control group in completeness（4.6±0.5 and 3.8±0.9，t=7.320，P<0.001），clarity（4.4±0.6 and 3.6±1.0，t=8.040，P<0.001），timeliness（4.3±0.7 and 3.2±1.1，t=8.040，P<0.001），and engagement（8.5±1.2 and 6.1±1.8，t=10.450，P<0.001）. Medical staff demonstrated significantly higher patience levels（87.5% and 70.8%，χ²=6.670，P=0.010）. Conclusion The ICU intelligent guidance system significantly improved patients’ and families’ cognition doctor-patient communication，and satisfaction，warranting further validation via randomized controlled trials. This study provides an paradigm for health education in critical care and holds important reference value for advancing smart healthcare.
