1. First of all, evaluate the degree of knowledge and understanding of the personnel involved in the warning education of nursing adverse events. You can understand the cognition, cause analysis and preventive measures of adverse events through questionnaire survey, knowledge test or group discussion.

2. Secondly, evaluate whether participation in education has changed the behavior and practice of participants. For example, observe whether we have taken more cautious steps in actual nursing work, followed the norms and procedures, and strengthened communication and teamwork.

3. Then, collect the feedback and reaction of the participants to understand the evaluation of the content, form and method of education. The opinions and suggestions of participants can be collected through questionnaires, interviews or group discussions to evaluate the acceptance and satisfaction of education.

4. Finally, feedback the evaluation results in time, analyze the data, find out the improvement direction and strategy, and continuously track the effect. Through long-term monitoring and feedback, we will constantly improve and perfect the content and methods of education and improve the effect of education.
