RESUMO
BACKGROUND: Despite the increased demand for nurses worldwide, discussion of nurses' duty to care is lacking. This study aimed to examine nurses' duty to care during the coronavirus disease 2019 (COVID-19) pandemic and to identify the influencing factors. METHODS: This was a cross-sectional descriptive research study that used a structured online questionnaire. Registered Korean nurses answered a demographic questionnaire and the Nash Duty to Care Scale. RESULTS: Age and employment at tertiary hospitals increased nurses' duty to care. Male sex, a highly educated status, and employment at tertiary hospitals increased the perceived risk. Male sex and employment at tertiary or general hospitals increased confidence in the employer, while a high level of education and a longer total clinical career decreased the same. Age and a higher monthly wage increased perceived obligation. Age, lack of religious beliefs, and clinical experience of 3-7 years increased professional preparedness. CONCLUSION: Without enough nursing manpower, the disaster response system could prove to be inefficient. Considering that adequate nurse staffing is essential in disaster management, it is crucial to ensure that nurses have a will to provide care in the case of disaster. In the future, a more active discussion on nurses' duty to care and additional research on factors that may hinder and facilitate the same are needed.
