Effect of Podcast-Based Education on Preoperative Nursing Competency and Evidence-Based Knowledge in Nursing Students

Preoperative nursing care requires structured knowledge, clinical reasoning, and competency-based training to ensure patient safety and optimal surgical outcomes. Despite advances in educational technology, limited evidence exists regarding the use of podcast-based learning specifically in preoperative nursing education. This quasi-experimental controlled study will be conducted among second-year undergraduate nursing students enrolled in the Surgical Nursing course. Participants will be randomly assigned to either a control group receiving standard face-to-face instruction or an intervention group receiving standard instruction supplemented with podcast-based educational materials. The podcast intervention will consist of short audio recordings (maximum 5 minutes each) focusing on preoperative patient preparation and assessment. The recordings will be developed by the research team based on current evidence and curriculum objectives. Students in the intervention group will have access to the podcasts for four weeks and may listen to them as frequently as desired. Outcome measures will include: Perceived Preoperative Nursing Care Competency Scale (PPreCC-NS), a validated Likert-type instrument assessing students' perceived competency. Evidence-Based Nursing Practices in Perioperative Care Knowledge Form, a structured true/false questionnaire evaluating knowledge levels. Assessments will be conducted at baseline (prior to the intervention) and four weeks after the educational exposure. Data will be analyzed using appropriate parametric or non-parametric statistical tests depending on distribution characteristics. Statistical significance will be set at p \< 0.05. This study is a minimal-risk educational intervention and does not involve pharmacological or invasive procedures.
