Purpose : The aim of this article is to describe the nursesʼ experiential learning mechanism on patient safety. Methods : To analyze nursesʼ learning experiences on patient safety cases, a focus-group interview method was used. The Kolb’s experiential learning model was used as a reference model. Findings : Without deep reflective reasoning about specific experiences, there is no creative or innovative solutions to experiment actively. Nurses are likely to be reluctant learners when there is no systemic support from formal departments which is in charge of patient safety and quality of care. Conclusion : In order to build patient safety culture in hospital, there should be efforts to make nurses as active learners on patient safety as well as to build learning environments in medical units.
