Background: Nursing students who participate in clinical practice in hospitals are not ready to provide quality care in maximizing patient safety. This study aims to develop a Problem Based Learning Patient Safety (PBLPS) conceptual model design that stimulates high-level thinking soft skills for students and finds PBLPS learning tools. Method: Research and Development (R&D), which is a research method that aims to produce new products through a development process. The stages of the research method consist of 3 stages, namely: the preliminary study stage; model development stage; model testing stage. The research subjects were nursing students at tertiary institutions in Samarinda city who had taken patient safety management courses, totaling 162 people. Data were analyzed using the Wilcoxon test. Results: Patient safety goals have not been implemented properly by students who practice clinical practice in hospitals. Students state that case-based learning can improve both hard skills and soft skills. The design of the integrated Problem Based Learning (PBL) learning model and the integrated PBLPS learning tools developed are RPS and integrated PBL-based modules on patient safety management. The results of the analysis of the soft skills assessment of high-level thinking students who practice in hospitals in the first year and the second-year show that there are differences in the results of the assessment of high-level thinking soft skills in the application of patient safety. Conclusion: The Problem Based Learning Patient Safety (PBLPS) conceptual model can stimulate high-order thinking soft skills for students in patient safety management practices in hospitals.
