Purpose:: This study identified the factors affecting the clinical competence of emergency unit nurses caring for foreign patients.

Methods:: This study utilized a descriptive correlation design. Participants were 112 emergency unit nurses working in different hospitals designated as the government’s emergency medical centers and agencies in 2018. The collected data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson’s correlation coefficients, and multiple linear regression analysis.

Results:: Subjects’ clinical competence showed positive relationships with cultural competency (r=.45, p<.001) and intercultural communication (r=.53, p<.001). Factors that affect the clinical competence of subjects showed intercultural communication (β=0.38, p=.001).

Conclusion:: It is necessary to develop programs to improve intercultural communication, factors that influence clinical competence of emergency unit nurses, and apply them to practical fields.
