Objectives: This study aimed to identify factors influencing death anxiety among nurses in COVID-19 dedicated wards. Methods: A secondary data analysis was conducted using data from Jung (2022), collected between March and April 2022, involving 123 nurses working in COVID-19 dedicated wards. The effects of death attitudes toward death, self-esteem, and perceived risk of infectious respiratory diseases on death anxiety were examined for different anxiety levels. Results: Significant differences were found in death attitude and perceived risk of infectious respiratory diseases between different anxiety levels. In the low-anxiety group, attitude toward death, self-esteem, and perceived risk were significant factors, whereas in the high-anxiety group, only attitude toward death had a significant effect. Conclusion: To reduce death anxiety among COVID-19 ward nurses, it is essential to assess anxiety levels, develop targeted interventions, and evaluate their efficacy.
