Objectives: This study aimed to identify the factors that influence awareness and willingness to use long-term care insurance among the elderly. Methods: The participants of the study were 1,000 adults aged 19 or older. Factors were identified using descriptive statistics, chi-square analysis, and logistic regression analysis. Results: Awareness of long-term care insurance was higher in women with high monthly income, experience using long-term care insurance, easier access to medical care, and a sufficient number of long-term care facilities. In addition, factors related to the willingness to use long-term care insurance were female sex, economic activity, high monthly income, and experience using long-term care insurance. Conclusions: To efficiently utilize these services, it is necessary to have a correct awareness of long-term care services and utilize them appropriately when visiting a hospital because of a geriatric disease. This can also be used as an educational path. In addition, efforts should be made to reduce the economic burden of long-term care services, and information on costs should be provided.
