Hand Hygiene Effectiveness

This single-group quasi-experimental study will evaluate the effectiveness and durability of a fluorescent hand hygiene training program for first-year nursing students at a Polish university. Students will complete the WHO Hand Hygiene Knowledge Questionnaire and undergo Glo Germ-based fluorescent assessment of handwashing technique at baseline, immediately after the training, approximately two weeks later, at the end of the first semester, and just before their first clinical placements. The primary objective is to determine whether the training improves and sustains hand hygiene technique quality over time, while secondary objectives include changes in hand hygiene knowledge and the relationship between knowledge and technique
