Post-traumatic Stress and Related Factors Among Hospital Nurses during the COVID-19 Outbreak in Korea

COVID-19 is an ongoing worldwide infectious disease pandemic. The purpose of this study was to investigate post-traumatic stress and related factors among hospital nurses during the COVID-19 outbreak. The subjects of this study were 300 nurses who worked in three general hospitals that operated National Designated Isolation Unit (NDIU) wards during the COVID-19 outbreak. Self-reporting questionnaires were used to collect data on post-traumatic stress, general characteristics, and work-related information. The average post-traumatic stress score was 20.68 ± 19.5 points and 36.7% of participants were at high risk of post-traumatic stress disorder (PTSD). The odds ratio (OR) for PTSD was higher for nurses who worked in the NDIU ward (OR = 16.31, 95% CI = 3.79–70.32), who responded that nurse staffing was poor (OR = 3.03, 95% CI = 1.01–9.10), and who responded that they experienced COVID-19 symptoms (OR = 3.83, 95% CI = 1.89–7.75). Total 36.7% of nurses were at risk of PTSD and the factors related to PTSD were the work department, nurse staffing, and experiencing COVID-19 symptoms. These results could be used to manage PTSD and provide psychological support of nurses during infectious disease epidemics, such as COVID-19.
