Abstract [en] Background: Healthcare-associated infections remain a major patient safety concern, and hand hygiene is central to their prevention. Adherence to hand hygiene recommendations remains inconsistent and is influenced by individual and contextual factors. Aim: To investigate factors influencing hand hygiene behaviour among healthcare workers and nursing students. Methods: The thesis comprised one qualitative descriptive study and three quantitative comparative survey studies conducted at a Swedish university and university hospital. Study I involved focus group interviews with 38 healthcare workers. Studies II and III surveyed the same sample of 201 first- and final-semester nursing students and registered nurses using World Health Organization hand hygiene instruments. Study IV compared survey data from independent samples of first- and final-semester nursing students and registered nurses collected during the peak of the COVID-19 pandemic in 2020–2021 and in the post-pandemic period in 2023. Results: Healthcare workers perceived infection prevention information as accessible but reported limited direct feedback on hand hygiene performance. An electronic reminder system was generally accepted when privacy was protected and feedback was provided at group level. Hand hygiene knowledge was moderate to good, but first-semester students had lower scores than final-semester students and registered nurses, and knowledge gaps remained across all groups. Attitudes towards and perceptions of hand hygiene differed between nursing students and registered nurses. Total knowledge scores did not differ significantly between 2020 and 2023, whereas the perceived importance and prioritisation of hand hygiene were lower in 2023. Conclusion: Factors influencing hand hygiene behaviour reflect an interplay between knowledge, perceptions, experience, social influences and institutional conditions. Sustaining hand hygiene as a patient safety priority requires continuing education, constructive feedback, professional role modelling and organisational reinforcement.
