This study investigates the prevalence and reasons for missed nursing care and examines whether nurses' work experience is associated with missed nursing care. Conducted at a public Danish university hospital, the study used the Danish version of the MISSCARE survey, which assesses nurses' perceptions of missed nursing care elements and their reasons. The survey was distributed to 1,241 nurses, with a response rate of 50.3%, and 42.6% completing the questionnaire fully. Results show that over two-thirds of nurses reported frequent missed elements such as emotional support, patient bathing, ambulation, mouth care, interdisciplinary conferences, documentation, and medication effectiveness. The primary reasons for missed nursing care were inadequate staffing, unexpected increases in patient volume, urgent patient situations, heavy admission and discharge activity, and communication breakdowns. Nurses with less than 5 years of work experience reported more missed nursing care, particularly in fundamental care elements. The study contributes to the global understanding of missed nursing care by highlighting the importance of addressing staffing levels and providing targeted interventions to improve nursing care quality and patient safety.This study investigates the prevalence and reasons for missed nursing care and examines whether nurses' work experience is associated with missed nursing care.
