Background: Pressure injuries (PIs) are preventable yet remain a major global patient safety concern and an indicator of nursing care quality. Enhancing nursing students’ knowledge and skills through simulation-based education is essential for PIs prevention. Design: Pre- and post-test, single-blind, randomised controlled trial (ClinicalTrials.gov ID: NCT06634095). Methods: This study was conducted with Nursing Department students at a university in eastern Turkey. The sample of the study was determined by power analysis method and consisted of 94 nursing students including 47 experimental and 47 control groups. The experimental group received pressure injury training based on a MSSPS. ‘Descriptive Information Form’, “Attitudes Towards Clinical Practice Scale for Nursing Students”, “Pressure Injury Management Self-Efficacy Scale for Nurses”, “Pressure Injury Knowledge Test”, “Pressure Injury Skill Evaluation Form” and “Pressure Injury Assessment Form” were used to collect the data. Results: The experimental group demonstrated significant improvements in clinical practice attitudes, self-efficacy, PIs knowledge, skill performance and wound assessment scores compared with the control group (p < 0.05). Conclusion: MSSPS effectively enhanced nursing students’ knowledge, self-efficacy, clinical attitudes and skills in PIs prevention and management. © 2025 Elsevier Ltdeninfo:eu-repo/semantics/closedAccessClinical PracticeMoulageNursing StudentsPressure InjurySelf-EfficacySimulationStandardised PatientArticle90Q1Q1
