Purpose: This study aimed to develop a program using the Room of Errors (ROE) technique to enhance the patient nursing student’s safety competencies and determine the effectiveness of simulation-based education. Methods: We conducted a methodological study using the ADDIE model for program development (Molenda, 2003). During the ROE activities, students identified errors that threatened patient safety. The program's effectiveness was evaluated in the implementation phase by measuring students' confidence in patient safety using a one-group pretest-posttest design. Results: Participants' satisfaction with the ROE program was 4.90 ± 0.36 on a 5-point Likert scale. The pre- and post-ROE program patient safety confidence scores (H-PEPSS) were statistically significant, increasing from 3.62 ± 0.54 to 4.19 ± 0.60. Participants' subjective evaluations were generally positive, indicating increased insight, confidence, and vigilance in error prevention. Conclusion: Based on this study’s significant findings, it would be beneficial to encourage students and healthcare providers to utilize ROE programs to enhance patient safety competencies.
