A questionnaire survey on the personal and work factors related to work engagement among intensive care unit nurses concerning their recovery experiences and the nursing practice environment was conducted using a web‐based tool. Two individual factors (demographics and experience on recovery from job stress) and four work factors (work employment type, nursing method, COVID‐19 nursing experience, and nursing practice environment) were surveyed. Data from 244 participants were obtained, and survey items were analyzed using a multiple regression analysis with work engagement as the dependent variable. The results show that 3–5 years of nursing experience is significantly associated with lower work engagement. Conversely, certifications for higher‐level and specialized nursing, mastery experience such as learning new things, 1–9 days/month of COVID‐19 nursing experience, and suitable nursing practice environment were significantly associated with higher work engagement. These factors are considered important for improving the work engagement of intensive care unit nurses.
