This study was conducted to define the concept of social stigma related to COVID-19 and to identify attributes of nurses with experience in nursing COVID-19 confirmed patients. The study analysis method used the hybrid model of Schwartz-Barcott and Kim, and data was collected from literature related to social stigma and 7 nurses who had experience caring for confirmed COVID-19 patients. As a result of this study, the social stigma related to COVID-19 of nurses who have experience nursing confirmed patients was derived into three attributes. The three areas were derived from undervaluation, discrimination, and negative stereotypes. As a result, social rejection, social isolation, and lack of social support were found. As a primary result, cognitive response to inequality, emotional response to increased stress, increased anxiety, disappointment, alienation, and avoidance appeared. As a secondary result, negative self-concept, destruction of self-integration, self-stigmatization, and job satisfaction were shown. As a result, this study is meaningful in that it provided a practical foundation for a strategy to reduce social stigma related to COVID-19 of nurses who have cared for COVID-19 confirmed patients.
