The third paper describes research findings from three qualitative studies aimed at extending expertise in practice. The first study investigated early recognition of patient problems by expert intensive care nurses. The second study used a reflective practicum with novice nurses to extend their critical thinking skills in practice. The third study used a reflective practicum to teach pediatric critical care nurses the content of family sensitive care. In learning family sensitive care, the staff nurses extended their expertise to include this in their pediatric intensive care practice. These studies provide a direction for future interventions and research to extend knowledge in practice.
