Abstract:

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.
