Integrating UpToDate with case-based learning enhances residents' clinical decision-making and training satisfaction in critical care training.

Objective: Case-based learning (CBL) enhances medical students' clinical competence but faces limitations like reliance on outdated information and insufficient evidence-based decision-making support. UpToDate, an evidence-based, continuously updated clinical resource, provides current data, standardized pathways, and improved application skills. Integrating UpToDate into CBL offers potential for enhancing the accuracy, timeliness, and multidisciplinary nature of learning. This study developed the "UpToDate-CBL" model for critical care education and evaluated its effectiveness in clinical teaching. Methods: Sixty standardized residency trainees were randomized to a CBL group ( Results: No significant differences existed in theoretical knowledge (86.67 ± 5.02 vs. 84.53 ± 3.79, Conclusion: Compared with the CBL model, the UpToDate-CBL approach significantly enhances students' proficiency in interpreting clinical parameters and clinical decision making, while also effectively fostering their motivation for self-directed learning. This approach demonstrates distinct advantages in clinical reasoning training within the context of critical care medicine; nevertheless, it cannot achieve breakthroughs in teaching basic knowledge and clinical skills.
